Canters Behavior Essay Example for Free

Canters style EssayDylan is a five year old boy that from the very counterbalance showed disruptive behavior frequently passim the classroom. Dylans teacher has well- documented his actions and she has asked the administrators of the school for support, plus she has also referred Dylan to conduct a behavioral evaluation. The teacher has utter with Dylans p atomic number 18nts on many occasions and they say his behavior was the same at home. Dylans parents also stated that his disruptive behavior was his way of pursuit attention. During this m Dylans behavior is generally getting more and more disruptive and aggressive. With the teachers observation logs, Dylans is having a rough time playing along with opposite baby birdren and is having a difficult time following restrainions. Just about every day Dylan is hitting, yelling, or is taking things away from the other childrens hands to get the teacher to come over and see what is wrong. Many of the children have made the decision to ignore him or to just act as in another direction away from him.With his academic skills he is far more behind than the other students in class. Dylan has the knowledge to finish the activities, but he is rarely in the mood to do so. Sometimes the issues begin when the teacher break throughs giving everyone there assignment and is working quietly, thats when Dylans behavior sincerely goes through the roof, and when he is told what to do about his behavior. While the disruptive behavior remains the teachers patience with Dylan starts to run very thin and begins to female genitaliacel out to every unacceptable behavior that he shows.These actions start to have a negative influence on the attitudes of the remaining students. Most of students start to copy Dylans actions while the others students are not finishing their work. This can result in the teacher needing to spend a lot of time having to deal with Dylans behavior and not having enough time with to teach. Teach ers have many avenues to teach students successfully and professionally take care of unacceptable behaviors. One step would be to use the Canters Behavior Management Cycle, into effect (Canters 2006).Canter has three steps first, effectively communicating explicit directions, second, using behavior reading and third, taking corrective action. When starting to use Canters cycle teachers will need to take the time to use two very important methods at the start of the school year this is going to help minimize disruptive behaviors. One, creates lessons on appropriate behavior for specific parts of the school day, activities, and transitions (Canters p. 31) and second creates a, Responsible Behavior Curriculum, for the first two weeks of the school year (Canters chap. ).This curriculum will set the tone of the class for introducing what is acceptable with appropriate behaviors, and that they are expected to follow the rules from students throughout the school day. Teachers should start with Canters behavioral cycle Dylans teacher needs to start with the first step. The first step will need to that the teacher to turn over clear, specific and detailed directions. The directions are being given to Dylan and he is to follow them precise. When giving directions they need to be quite clear and on point at all costs.The teacher needs to always evade being unclear to the students, if they know what is expected of them they will follow. The teachers directions should contain precisely how the students are to conduct themselves in the classroom. Explicit directions should include the, expectations for student verbal behavior, physical movement, and participation (Canters p. 53). The teacher needs to never make the mistakes of assuming what the students know, what the expectations of their behavior is, and the teacher should always recall the students on a daily basis what is expected of them.The teacher has to have a firm grip on effective intercourse while having detai led directions, she can continue on to the next important step. This step involves using Behavioral Narration (Chapter 9), which is how the teacher will positively set off Dylan to follow directions. One way of achieving this is to give Dylan and the class as a whole effective positive feedback (Canters p. 58). When giving detailed directions, the teacher should look to take note which student within seconds of giving the directions to see who is really following the directions that were given.The teacher needs to point out who is sense of hearing to the directions and how the students are following the directions. At the importation when Dylan is being difficult the teacher does not need to focus on giving Dylan more attention, but try to focus on the students who are listening and making good choices. When trying to change the un requireed behavior the teacher needs to try to use the behavioral narration, which will allow the teacher to geminate the rules and define the accep table behavior of students who are making good choices.This will show the students their teacher is mindful of the actions that are taking place and is more than alert to fix any problems that may arise. When the teacher acknowledges the acceptable behaviors and recaps the directions it sets a wonderful start and a positive atmosphere in the room. The class will be regularly recalled on what is expected from their behavior, students are expected to follow the rules, students who were not able to receive or finish their assignment will have time to finish and catch up with the rest of the class.Students will be given a chance to have time to catch up when needing be. With this step it can go the extra mile by setting up an award-system in place. For example, when the directions are given the teacher notices Dylan is sitting where his seat is and he is working on the assignment that was given to him, wherefore the teacher would say to his friends, Look at Dylan he is sitting at his seat and is working on his assignment so nicely I am going to have to give Dylan his extra class point that he earned in class.Ultimately this will inhale Dylan to have more acceptable behaviors and the other students to strive for the goals that are set up for the students to obtain. The last action of the cycle is corrective action taken (Chap. 10). When the direct instructions have been given out, looking to observe the group for ten seconds, reports were made on students that are on the right track, and when Dylan is not following directions then you must use the corrective action. This is done by directive verbal statements or disciplinary consequences (Canters p. 9).The teacher needs to peacefully reaffirm the instructions and send word the students of their penalties and what their actions have caused. This can also let Dylan and the entire class knows and understands that you are very serious about bringing an end to unacceptable behavior. Students need to know, understand , and be aware of the effects for disrupting the class and just making unacceptable choices. When the unacceptable behavior remains untouched the procedure needs to be shadowed with the same reaction.Every time a student shows a disruptive behavior it should be dealt with immediately and that the penalties produced is entirely from the students actions. In order for students to call for the rules must be enforced. Students have to have structure so they can flourish, they need to know what is expected of them on day one. Once a child knows that they cannot get away with disruptive behavior they will tend to not want to misbehave. If there is a reward system they will definitely want to have a reward at the end of the day or week. Consistency is the key to keeping students where they need to be in order to have peace in the room.

Effects of Emotion in Eyewitness Recall and Recognition

Effects of Emotion in Eyewitness Recall and RecognitionAaron GlogowskiHouston, K. A., et al. (2013). The ablaze Eyewitness The Effectsof Emotion on Specific Aspects of Eyewitness Recall and Recognition Performance. Emotion, 13(1), 118-128. doi 10.1037/a0029220In the world of criminal science, there argon several factors that can interfere with the accuracy of eyewitness reports. This article, by Kate Houston and her team, delves into the effects of emotion on eyewitness encounters. The main argument that they are looking at focuses on ostracise emotion enhancing central memory while impairing the skirting(prenominal) memory, where central memories are the main details that occurred, likely relating specifically to the action of the offensive activity, and peripheral memories are the smaller details that were happening around the crime.Houston nones that in spite of all of the writings on eyewitness memory, very few studies attempt to instal a correlation between it and memory. She goes on to hypothesize that negative correlations will indeed enhance the central memory of the event, further exploring details like the crime itself. In her observations of otherwise studies however, she does note that high stress scenarios tended to cause subjects to forget details almost the perpetrator of the situation, at least in the case of a previous study on soldiers interrogations. In order to stress their hypotheses, Houston and her team set up two different experiments designed to test recall memory performance, as well as the participants ability to identify the perpetrator of the crime, both associated with negative horny response.In their prototypic-year experiment, the team hypothesized that a negative delirious response would allow the participants to more easily describe details about the perpetrator. They gathered a participation throng of 101 students from the University of Aberdeen (30 males 71 females) to engage in the study. They divided the conv ocation into two sub throngs. The aggroup of 51 was shown a video that was meant to induce an stimulated response, and the group of 50 was shown a video intended to illicit a neutral response from the participants. Both videos used the same actors and scenarios up to the point in which the story deviates to the emotional induction.Once the participants had watched their respective videos, they were asked to answer a brief survey about how the video made them feel. They were given several different emotions, as well as a neutral I feel nothing option, and were asked to rank all of these emotions on a scale of 0-3 (0 cosmos not at all, and 3 being very much). After they rated what they were feeling, the results were collected and the participants were given a 20 minute wait period in which they had to fill out a questionnaire on likes and dislikes, though this questionnaire was truly only present to provide a distraction for the next part of the experiment. The participants were t hen asked to write down as many details about the video that they could remember.In the results of the experiment, Houstons team discovered that the emotion-inducing video tended to cause much higher responses to negative emotions than the neutral video did. They also noticed that the group viewing the emotional video recalled the events of the emotional moment in much more clarity and complete detail than the neutral video control group, however, they could not recall details about the perpetrator as well. Their data also shows that there is not a fundamental correlation between the negative emotional responses and the amount of information given about the perpetrator and the small moment. This data concludes that those experiencing negative emotions tended to focus their attention directly on the perpetrator, however, there was no significant difference in their ability to describe the perpetrator when compared to the results from the neutral video control group. While the idea that focus is altered in a critical moment coincided with the evidence, the data could not identify any significant difference in memory and recall.The second experiment was designed to test whether or not negative emotions and stress impair the individuals ability to identify a perpetrator when they are presented with a series of options (in this case, a word picture line-up). Houstons team used two separate moving-picture show line-ups for the experiment angiotensin-converting enzyme in which the perpetrators photo was present, and another where the perpetrators photo had been replaced by one that looked very corresponding to them. The team made sure to select alternates for the replacement photo based on resemblance to the perpetrator jibe to a method recommended by the Police and Criminal Evidence Act used to identify criminals in the United Kingdom.They split up a group of 233 participants into relatively even subgroups at the beginning of the study. They began the study i n the same way as the first experiment two separate videos were shown, one emotional, one neutral, then the participants were asked about their emotional responses to the videos, and given time after the emotional response portion. Once the period after the emotional response survey had passed, the participants complete a recall survey about the videos, then they divided the groups again into two separate subgroups. One subgroup was shown the picture line-up containing the perpetrators image, while the other was shown the line-up with the face doubles image.The results of the second experiment confirmed the teams previous theories that the video was successful in eliciting an emotional response, and that emotional responses were similar to the previous experiment, based on their initial observations.The second set of findings turned out to be in accordance with the initial hypothesis of the second experiment. Participants who watched the emotional video were much more likely than th ose who watched the neutral video to incorrectly identify an innocent target as the perpetrator. Around 25% of the time, participants in the group in which the perpetrators photo was included would claim that the perpetrators picture was not among those in the line-up. Those who saw the neutral video were much more likely to identify the real perpetrator (40.4% as opposed to 27.1% from the emotional video group). In the group in which the perpetrators photo was absent however, there appeared to be no significant correlation between emotional response and the answers given. The recall results for this experiment were very similar to the recall results for the first experiment.In collecting their results from the second experiment, Houstons team arrived at several conclusions based on the data that had been collected. Their data further supported the idea that deal exposed to negative emotional experiences focused more on the perpetrator, but less on the rest of the situation, but th ey no longer had any virtuoso of improved environmental detail. They both however showed the same level of accuracy in describing the target. The photo line-up tests show very different results however, showing that those exposed to negative emotional experiences would more likely identify the wrong target when the targets picture appears along with others similar in appearance and features to them. When the target was not shown however, the emotional video groups tended to have similar results to those in the neutral video group.In the teams conclusion to their article, they discussed the probable reasoning behind the discrepancies in their experimental results. They note that the environmental results differ between the experiments, showing that it may be unreliable. The data as a whole shows that negative emotional responses may have different results on eyewitness testimony, depending on the situation.

Disadvantages of Physical Education

Disadvantages of forcible EducationMandatory bodily pedagogy for students in childlike through game croping is designed with the best intentions like promoting a wellnessier lifestyle, and aiding students in uncovering their potential talent. But as good as these intentions whitethorn seem they each(prenominal) f each swindle of its intents due(p) to restricting students freedom of choice, a mounting work out deficit, and constant browbeat. in all these countless shortfalls campaign a string of out of the blue(predicate) problems such as impairing donnish success, vast emotional damage, immense psychological disparage, and painful sensible damage. Although umteen p arnts consider physiologic cultureal activity as an important part of the public genteelness system, children should non put on to participate in personal learning if they do not necessity to. Physical Education should not be authorization in public informational activity for students in e asy through high school since it impairs learning, emotional, and physical harm to students causing immense damage that be not beneficial to students.I am troubled about mandatory physical education for students in elementary through high school. Physical education went through a long journey to mystify what it is today. It all started in 776 B.C. where Greeks held the first Olympiad. subsequently on in 1814 Demark establishes the Bill of 1814 the first ever compulsory physical education bill. In 1825 Charles Beck aims the first teacher to teach physical education. In 1866, calcium passed the physical education legislation, becoming the first state to ever do so. Afterwards in 1896 A sos, Greece held the first modern Olympic game (Zeigler). Throughout all these years, physical education maintained its core values, fostering an environment for students to improve their comprehension, skill sets, capacities, and principles (Kelso). Problem starts when physical education becomes ma ndatory especially in schools where all these values begin to shift for the worst part. Students lose their freedom of choice, being forced into a highly competitive instauration of sports where injuries, psychological drama, and fear of losing become a overabundant possibility (FLEMING). Whether physical education should be made mandatory in public education for students in elementary through high school is a highly controversial topic since physical education comes with a heavy price by stripping students of their freedom of choice, and a raise education due to lack of funding.Making physical education mandatory in public education for students in elementary through high school intensifies an ongoing budget crisis. In just the state of California alone there is already an 11.2 billion dollar deficit. Across the United States, state levy revenues are brush up because of the worldwide economic slump. Each year schools receive solely limited amounts of state and federal funding, funds depend on commonwealth and student academic performance (BBC). According to the Los Angeles Times galore(postnominal) schools are already struggling with increased furloughs, and widespread teacher layoffs(Mehta). If physical education were to become mandatory then funds would be stretched even more sparsely. For example making physical education compulsory in elementary and high schools nationwide would be establishing an only if new department just for physical education, and building new gyms and football fields.

I cannot argue the fact that physical education allows students to try out diverse sports and experience a variety of sports. Nevertheless students can uncover their talents outside of school sidestepping the bullying and physiological damage that usually occurs with physical education. According to a nationwide poll in 2004 done by Southwest Wisconsin Youth Survey 19% of all teens responded to more or less or quite a bit when asked how much do you worry about being picked on or physically evil by another(prenominal) teen? (SWYS). Also, 19% is an enormous number that means that two out of every ten students are being bullied. Besides 19% is an understatement since most students that are bulled are too ashamed, scared, or hurt to admit it. There are countless more students that are being bullied but are not documented. Students have a hard time learning when they are constantly being bullied and put down by fellow classmates. Being roaring in sports only occurs when both talent and interest are mixed in.

Imaging Techniques for Intestinal Obstruction

Imaging Techniques for Intestinal stopThe keen gut is the only part of the gastro enteral package that is essential for life. It serves a neuroendocrine function, a digestive function (propulsion, mixing and absorption of food), and a secretory function. The liver, gallbladder and pancreas atomic number 18 accessory organs of the digestive clay that is closely associated with the junior-grade catgut. The villous surface improves absorption by increasing the overall surface ara. In addition to absorption nutrients, it is responsible for most body of water reabsorption in the GI tract (Edward, 1998).The miserable intestine is made up of three segments, which bring a stretchage from stomach (the opening amid stomach and small intestine is called the pylorus) to extended intestine. It is duodenum, jejunum and ileum. The duodenum is this short section is the part of the small intestine that takes in semi digested from stomach through the pylorus and continues the digestion p rocess. The duodenum also uses rancor from the gallbladder, liver and pancreas to help digest food. The jejunum is the middle section of the small intestine carries food through rapidly, with wave-like muscle contractions, towards the ileum. The last segment is ileum. The ileum is the longest part of small intestine. It is where most of the nutrients from food are absorbed before emptying into the great intestine (UPMC, 2010).By the time food reaches small intestine, it has already been broken up and mashed into liquid by stomach. Each day, small intestine receives between bingle and three gallons (or six to twelve liters) of this liquid. The small intestine carries out most of the digestive process, absorbing almost all of the nutrients get from foods into pitchstream. The sm opposites of the small intestine make digestive juices or enzymes that work together with enzymes from the liver and pancreas to do this. Although the small intestine is narrower than the large intestine, it is actually the longest section of the digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of body (UPMC, 2010).1.2 overlarge IntestineThe large intestine is larger in diameter than the small intestine. It begins at the ileocecal junction, where the ileum enters the large intestine and ends at the anus. The large intestine consists of the colon, rectum and anal erectal. Its direct function is to secrete mucin and form stool for excretion. It reabsorbs water and electrolytes but to a much lesser extent than the small intestine. It does not realise sodium cotransport system (Edward, 1998). Unlike small intestine, the large intestine levys no digestive enzymes.The debate of the large intestine has the same types of tissue that are found in otherwise parts of the digestive tract but there are some distinguishing characteristics. The mucosa has a large number of goblet cells but does not have any villi. The longitudinal mu scle layer, although present, is incomplete. The longitudinal muscle is limited to three district bands, called teniae coli that run the entire length of the colon (National malignant neoplastic disease Institute, 2012).The rectum continues from the sigmoid colon to the anal canal and has a thick muscular layer. It follows the curvature of the sacrum and is firmly attached to it by connective tissue. The rectum and ends about 5 cm below the pitch of the coccyx at the beginning of the anal canal. The last 2 to 3 cm of the digestive tract is the anal canal, which continues from the rectum and opens to the outside at the anus. The mucosa of the rectum is folded to form longitudinal anal columns. The smooth muscle layer is thick and forms the internal anal sphincter at the superior end of the anal canal (National Cancer Institute, 2012).1.3 Intestinal ObstructionIntestinal parapet, also called ileus (from the Greek eilo, meaning to roll up) (Ivan, 1996). Intestinal barrier is refers to a lack of movement of the intestinal content through the intestine. Because of its smaller lumen, bulwarks are more common and occur more rapidly in small intestine, but they can occur in large intestine as well. Depending on the cause and place, obstruction whitethorn manifest as an acute problem or a gradually developing situation. For example, offer of the intestine could cause sudden total obstruction, whereas a tumor leads to progressive obstruction (Barbara, 2002).Obstruction of the intestine causes the bowel to become vulnerable to ischemia. The intestinal mucosal barrier can be damaged, allowing intestinal bacteria to invade the intestinal wall and causing fluid exudation, which leads to hypovolemic and dehydration. About 7L of fluid per day is secreted into the small intestine and stomach and usually reabsorbed. During obstruction, fluid accumulates, causing abdominal distention and pressure on the mucosal wall, which can lead to peritonitis and perforation (Unbound Medicine, 2011).Intestinal obstruction is most common on elderly individuals, due to the laid-backer incidence of neoplasm and other causative diseases in this population. In neonates, intestinal obstruction may be caused by imperforate anus or other anatomic ab naturalities. Obstruction may also be secondary to meconium ileus. In paediatric population, Hirschsprung disease can resemble intestinal obstruction (Christy, 2011).Intestinal obstruction occurs in two forms. Mechanical obstructions are those resulting from tumor, adhesions, hernias or other tangible obstructions. Functional, or adynamic, obstructions result from neurologic imp circularizement, such as spinal cord injury or lack of propulsion in the intestine and are often referred to as paralytic ileus. as indeedic or paralytic ileus usually related to inflammation or the disruption of innervation (Barbara, 2002).2 CAUSES OF DISEASEIntestinal obstruction can be caused by many different things. It occurs in two basic t ypes which is mechanical obstruction and paralytic ileus. Functional obstruction or paralytic ileus is one of the major causes of the intestinal obstruction in infants and children. It is common in the following situationsafter abdominal surgery, in which the effects of the anesthetic combined with inflammation or ischemia in the operative area interfere with conduction of nerve impulsesin the initial stage of spinal cord injuries (spinal shock)with inflammation related to intense ischemiain pancreatitis, peritonitis, or infection in the abdominal cavitywith hypokalemia, mesenteric thrombosis or toxaemiakidney or lung diseaseMechanical obstruction may result from the followingScar tissue in the belly, often called adhesions. This tissue can wrap around a piece of bowel. The contents of the bowel are prevented from moving normally through the intestineBowel that twits on itself or develops a bad kink. This is called volvulusFecal impaction or hard stool that cannot pass through the bowelCancer such as colon cancer or cancer of the pancreasHernias is protrusion of the abdominal contents through the abdominal wall(Barbara, 2002)3 PATHOPHYSIOLOGYWhen mechanical obstruction of the flow of intestinal contents occurs, a sequence of events develops as follows. First, intestinal obstruction occurs when gases and fluids accumulate in the area proximal to the blockage, distending the intestine. Gases arise primarily from swallowed air but also from bacterial activity in the intestine. Second, increasingly strong contractions of the proximal intestine occur in an driving force to move the contents onward. The increasing pressure in the lumen leads to more secretions entering the intestine and also compresses the veins in the wall, preventing absorption, as the intestinal wall becomes edematous. The intestinal distention leads to persistent vomiting with additional loss of fluid and electrolytes. With small intestinal obstruction, there is no opportunity to reabsorb flui d and electrolytes, and hypovolemia right away results (Barbara, 2002).If the obstruction is not removed, the intestinal wall becomes ischemic and necrotic as the arterial blood supply to the tissue is reduced by the pressure. If twisting of the intestine (e.g. volvulus) has occurred or if immediate compression of arteries (e.g. intussusception or strangulated hernia) results from the primary cause of obstruction, the intestinal wall becomes rapidly necrotic and gangrenous. Ischemia and necrosis of the intestinal wall eventually lead to decreased innervation and cessation of vermiculation. A decrease in bowel sounds indicates this change.Usually, the obstruction promotes rapid reproduction of intestinal bacteria, some of which produce endotoxins. As the affected intestinal wall becomes necrotic and more permeable, intestinal bacteria or toxins can leak into peritoneal cavity (peritonitis) or into the blood supply (bacteremia and septicemia). In time, perforation of the necrotic se gment may occur, leading to generalized peritonitis (Barbara, 2002).For functional obstruction or paralytic ileus usually results from neurologic impairment. Peristalsis ceases and distention of the intestine occurs as fluids and electrolytes accumulate in the intestine. In this type of obstruction, reflex spasms of the intestinal muscle do not occur, but the dispute of the process is similar to that of mechanical obstruction (Barbara, 2002).4SIGN AND SYMPTOMSWith mechanical obstruction of the small intestine, severe colicky abdominal pain develops as peristalsis increase initially, nausea and constipation characterizing small bowel obstruction. It may also cause drowsiness intense thirst, malaise and aching may dry up oral mucous membranes and the tongue. Borborygmi are audible rumbling sounds caused by movement of gas in the intestine and intestinal rushes can be heard as the intestinal muscle forcefully contracts in an attempt to propel the contents forward. These are loud enoug h to be heard without stethoscope. Palpation elicits abdominal nitty-gritty with moderate distention rebound tenderness occurs when obstruction has caused strangulation with ischemia.The signs of paralytic ileus differ significantly in that bowel sounds decrease or are absent and pain is steady. Vomiting and abdominal distension occur quickly with obstruction of the small intestine. Vomiting is recurrent and consists first gastric contents and then bile-stained duodenal contents. No stool or gas is passed. Restlessness and diaphoresis with tachycardia is present initial. As hypovolemia and electrolyte imbalance progress, signs of dehydration, weakness, confusion and shock are unpatterned (Barbara, 2002).Signs and symptoms of large bowel obstruction develop more slowly because the colon can absorb fluid from its contents and distend well beyond its normal size. Constipation may be only clinical effect for days. Colicky abdominal pain may then appear suddenly, producing spasms that last less than 1 minute each and recur every few minutes. Continuous hypogastric pain and nausea may develop, but vomiting is usually absent at first. sizable bowel obstruction can cause dramatic abdominal distention loops of the large bowel may become visible on the abdomen. Eventually, complete large bowel obstruction may cause fecal vomiting, continuous pain or localized peritonitis. Patients with partial obstruction may display any of the in a risqueer place signs and symptoms in a milder form. However, leakage of liquid stool around the obstruction is common in partial obstruction (Lippincott Williams Wilkins, 2007).5IMAGING MODALITIES5.1 Laboratory experimentLaboratory evaluation of unhurrieds with pretend obstruction should accept a complete blood count and metabolic panel. Hypokalemic, hypochlomeric metabolic alkalosis may be noted in patients with severe emesis. Elevated blood urea nitrogen levels are consistent with dehydration, and haemoglobin and hemotocrit level s may be increased. The white blood cell count may be elevated if intestinal bacteria translocate into the bloodstream. It can cause the systemic inflammatory response syndrome or sepsis. The development of metabolic acidosis especially in a patient with an increasing serum lactate level, may signal bowel ischemia (Patrick G. Jackson Manish Raiji, 2011).5.2 Plain RadiographyThe initial imaging take away of choice for confirming bowel obstruction with clinical signs and symptoms of intestinal obstruction should include pain upright abdominal radiography. This radiography can quickly define if intestinal perforation has occurred. The free air can be seen above the liver in upright films or left lateral decubitus films. Radiography is 60-70% sensitivity for perception of small bowel obstruction and it performs better in high-grade obstruction. Radiography can be find the diagnosis of small bowel obstruction include distended loops of small bowel, collapsed colon, the string of pear ls sign resulting from small amount of residual air compared with the large amount of retained fluid and pseudotumour related to distended fluid filled loops.In large bowel obstruction, it is important to note the degree of caecal distension on the plain abdominal films, since marked distension will point to the posit for urgent decompression to prevent caecal perforation. In patients with small bowel obstruction, supine views show dilation of multiple loops of small bowel with a paucity of air in the large bowel (Figure 4). Those with large bowel obstruction may have dilation of the colon with decompressed small bowel in the scenery of the competent ileocecal valve. Upright or lateral decubitus films may show laddering air fluid level (Figure 5). These findings show in conjunction with a lack of air and stool in the distal colon and rectum are highly suggestive of mechanical intestinal obstruction (Patrick G. Jackson Manish Raiji, 2011).LimitationsFails to diagnose the cause of obstruction in most casesIn obstruction of ileocaecal region, it may be difficult to determine whether the level in the proximal large bowel or distal ileumCannot faithfully detect the presence of ischaemic complication5.3 Computed Tomography5.3.1 Small bowel obstructionGenerally, it is considered the imaging modality of choice when plain abdominal radiography and the clinical features suggest an acute small bowel obstruction. CT is sensitive for detection of high-grade obstruction (90-96%). Although CT is highly sensitive and specific for high-grade obstruction, its cheer diminishes in patients with partial obstruction. In these patients, oral assembly line material may be seen traversing the length of the intestine to the rectum with no discrete area of transition. It useful inConfirming or excluding small bowel obstruction (versus pseudo-obstruction)Defining the degree and site of obstructionIdentifying the cause of small bowel obstruction (73-95% sensitivity)Confirming or ex cluding the diagnosis of ischaemia (90% sensitivity and specificity)The advantages areSuperior to enteroclysis in showing extraluminal masses, revealing abscesses, malignancy, anterior adhesions as well as features of strangulation.It is ability to depict other causes of an acute abdomenThe limitationsLower sensitivity (approximately 50%) for the detection and location of low-grade small bowel obstruction(Diagnostic Imaging Pathways, 2009)5.3.2 Large Bowel ObstructionIt indicated as an alternative to contrast enema in evaluation of large bowel obstruction, particularly with elderly and immobile patients. CT findings in patients with intestinal obstruction include dilated loops of bowel proximal to the site of obstruction with distally decompressed bowel. The presence of discrete transition point helps guide operative planning (Figure 6). Absence of contrast material in the rectum is also an important sign of complete obstruction. For this reason, rectal administration of contrast ma terial should be avoided (Patrick G. Jackson Manish Raiji, 2011). The advantages areDoes not quest insertion of rectal tube and contrast and is therefore better tolerated than a contrast enemaIn one study, successfully diagnosed colonic obstruction in 96% of patients and pseudo-obstruction in 93% of patientsThe limitations for this are false negative and false positive results and limited diagnostic with partly obstructing lesions (Diagnostic Imaging Pathways, 2009).Figure 6 axial computed tomography scan showing dilated, contrast- filled loops of bowel on the patients left (yellow arrows), with decompressed distal small bowel on the patients right (red arrows). The cause of obstruction, an increased umbilical hernia, can also be seen (green arrows), with proximally dilated bowel entering the hernia and decompressed bowel exiting the hernia (Patrick G. Jackson Manish Raiji, 2011).5.4 distinguish FluoroscopyContrast studies, such as small bowel fulfil, can be helpful in the dia gnosis of a partial intestinal obstruction in patients with high clinical suspicion and in clinically stable patients in whom initial conservative management was not effective. The use of water-soluble contrast material is not only diagnostic, but may be can use for therapeutic in patients with partial small-bowel obstruction. Contrast fluoroscopy may also be useful in determining the area of intestine that need for surgery (Patrick G. Jackson Manish Raiji, 2011).There are several variations of contrast fluoroscopy. In the small bowel follow-through study, the patient drinks contrast material, then serial abdominal radiographs are taken to visualize the passage of contrast through the intestinal tract. The advantage of small bowel follow-through is does not require nasointestinal intubation, and compared to enteroclysis, it is easier to perform and does not require additional expertise. The limitations for this procedure are they take time for contrast to reach the obstruction and barium is dilute because of excess residual intraluminal fluid resulting in non-uniform small bowel filling (Diagnostic Imaging Pathways, 2009).Enteroclysis involves naso- or aro-duodenal intubation, followed by the instillation of contrast material directly into the small bowel. Although this study has superior sensitivity compared with small bowel follow through, it is more labor-intensive and is rarely performed. The advantage enteroclysis are it has ability to gauge the severity of obstruction objectively. The limitations are it need for nasoenteric intubation and demonstration of extrinsic causes is sometimes difficult. Rectal fluoroscopy can be helpful in determining the site of a suspected large bowel obstruction (Patrick G. Jackson Manish Raiji, 2011)5.5 Magnetic Resonance Imaging (MRI)Magnetic resonance imaging (MRI) may be more sensitive than CT in the evaluation of intestinal obstruction. MRI enteroclysis, which involves intubation of the duodenum and infusion of contras t material directly into small bowel. It can more reliably determine the location and cause of obstruction. However, MRI is not universally available and very expensive (Patrick G. Jackson Manish Raiji, 2011).5.6 ultrasoundIn patients with high-grade obstruction, ultrasound evaluation of the abdomen has high sensitivity for intestinal obstruction, approaching 85 percent. However, because of the wide availability of CT, it has largely replaced ultrasonography as the first-line investigation in stable patients with suspected intestinal obstruction. Ultrasonography remains a valuable investigation for unstable patients with an ambiguous diagnosis and in patients that contraindication with radiation exposure, such as pregnant women (Patrick G. Jackson Manish Raiji, 2011).
