Total or mostly total intestinal aganglionosis is rare and invariably fatal. All patients with aganglionosis involving more than half of the small bowel have died with persistent intestinal obstruction and secondary malnutrition and infection. Recently, we experienced two cases of total colon aganglionosis extending to the middle of the jejunum in triplet. We report the cases with brief review of literatures.

Retrograde jejuno-gastric intussusception is an unusual complication after gastroenterostomy. It is very difficult to diagnosis this illness before endoscopy or operation, so a high clinical suspicion is needed to make the diagnosis .There have been only 300 reported cases of this illness. There are four types of jejuno-gastric intussusception that are defined anatomically. Intussusception of the efferent limb of the jejunum is the most frequent type. Although the causative factors are not well known, this disease has a poor outcome unless it's treats promptly within 48 hours. We report here a case of hematemesis caused by intussusceptum from the efferent limb to the afferent limb of Braun anastomosis.

PURPOSE: We evaluated the CT criteria useful for the diagnosis of the site of bowel perforation in patients with this or mesenteric injury caused by blunt abdominal trauma. MATERIALS AND METHODS: CT findings of 26patients with blunt abdominal trauma were retrospectively analyzed by two observers who were unaware of operative findings, and the results of their analysis were compared with those findings. Twenty cases of bowel perforation found at the jejunum (8), ileum (9), and colon (3), and six cases of mesenteric injuries were confirmed byoperation. We evaluated CT findings of 1) segmental bowel wall thickening, b) focal mesenteric fat infiltration, c) loculated fluid collection and d) extraluminal air adjacent to the bowel, and in addition analyzed the locations of ascites and free air, and the associated injuries of solid organs. RESULTS: The most common finding at the site of bowel perforation was segmental bowel wall thickening (17 cases), followed by focal mesenteric fatinfiltration (12 cases), loculated fluid (12 cases) and extraluminal air ajacent to the bowel (9 cases). Segmental bowel wall thickening was present at 34 sites, and the perforations were confirmed at 17 of these(50%). Focalmesenteric fat infiltration was present at 19 sites ; the perforations were proven at 12(63%). Loculated fluid collections were confirmed at 12/20 sites(60%), and extraluminal air adjacent to the bowel at 9/12(75%). Thepositive predictive value of criteria a, b, d, c) was 100%, and the positive predictive values of a, b, c) and a,d) were 60 and 67%, respectively. We observed ascites in 16 cases and intraperitoneal free air in 8 cases, the locations of ascites and free air did not, however, significantly correlate with the perforation sites. CONCLUSION: Extraluminal air adjacent to the bowel was the most specific criterion, and segmental bowel wall thickening wasthe most sensitive criterion. of all criteria, the finding 'a, b, c, d' most accurately predicted the site ofbowel perforation.

To determine the radiosensitivity and dose-urvival characteristics of jejunal crypt cells, experimental study was done using total 40 mice. Single irradiation of 1,000rad to 1,600rad was delivered to whole bodies of mice, using a cesium 137 animal irradiator. The number of regenerating crypts per jejunal circumference was counted, by using a jejunal crypt cell assay technique, and dose response curve was measured. The average number of jejunal crypt per circumference in control group was 140+/-10. Mean lethal dose(D0) of mouse jejunal crypt cell was 135rad.

Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.

Angiodysplsia of the small bowel is uncommon, but provably remains frequently undiagnosed. In the small intestine, angiodysplasia presents a taxing surgical problem and is uauslly diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that even when identified by frequently impalpable, and invisible to the naked eye unless they are actively bleeding at the time of surgery. Ensocopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few milimeters in diameter. We described a simple intraoperative endoscopic transillumination technique used successfully to identify an angiodysplasia in the jejunum prior to the small bowel resection. This report summarized our experience and review of literature.

The occurrence of the small intestinal adenocarcinoma is infrequent and the primary adenocarcinoma of the jejunum is rare. The survival of adenocarcinoma of the small bowel does not improve over the past three decades. Although symptoms appeared to be of long duration, most patients were diagnosed with advanced disease. All reports agree that these tumors are difficult to achieve good examination of the small bowel by both clinician and radiologist, so it cause a significant delay in diagnosis. The survival of these tumors appear to correlate with stage at presentation, and therefore early and aggressive diagnostic intervention seems to improve the outlook. We report a case of primary jejunal adenocarcinoma assoeiated with iron deficiency anemia with literatures review.

BACKGROUND/AIMS: We aimed to evaluate the clinical characteristics and prognosis of Crohn's disease (CD) in patients who showed proximal small bowel involvement using a nationwide Korean CD cohort. METHODS: We reviewed the data from a cohort of patients diagnosed with CD. The clinical outcomes of patients were evaluated according to the presence of proximal small bowel involvement. RESULTS: Among 1,329 patients with CD for whom complete disease location data were available, 222 patients (16.7%) showed involvement of the proximal small bowel. Compared to patients without proximal small bowel involvement, those with small bowel involvement were more likely to display stricturing behavior (19.8% vs 12.7%, p=0.020). The surgery-free survival of patients who showed proximal small bowel involvement was inferior to that of patients without proximal small bowel involvement (10-year surgery-free survival: 58.4% vs 67.7%, respectively, p < 0.001). Additionally, upper gastrointestinal involvement was more common in patients with proximal small bowel involvement than in those without involvement (odds ratio, 1.643; 95% confidence interval, 1.008 to 2.677). CONCLUSIONS: Proximal small bowel involvement is a poor prognostic factor for the surgery-free survival of Korean patients with CD. Proximal small bowel involvement should be evaluated in patients with CD for predicting long-term clinical outcomes.
