Laparoscopic sleeve gastrectomy can reduce morbidity and mortality in patients with morbid obesity, but it can cause complications such as a gastrointestinal leak. A 30-year-old morbidly obese female who had type 2 diabetes mellitus and hypertension with estimated body mass index of 40.2 kg/m2 was admitted. Laparoscopic sleeve gastrectomy was performed. On postoperative day 19, a leak was suspicious on physical examination and radiologic findings. Conservative management was performed, but the patient was hemodynamically unstable and imminently septic. After laparoscopic drainage procedure, esophagogastroduodenoscopy was performed and revealed the fistula opening at staple line just below gastroesophageal junction. Fibrin tissue adhesive was injected around the fistula and the esophageal covered stent was inserted to cover the leak. At 14th days after stent insertion, the barium study confirmed no more leak. In this case, we experienced that the esophageal stent insertion with fibrin tissue adhesive injection may reduce recovery time of the fistula developed after laparoscopic sleeve gastrectomy.

Bechet's disease(BD) is a chronic inflammatoroy condition involving several organs including gastrointestinal tract. Gastrointestinal tracts involvement in BD has been identified throughout the entire alimentary tract and commonly accompanies ulcerative lesions in the small and large bowel. It is debatable whether BD could be included among seronegative spondyloarthropathy (SPA).SPA usually occurs without overt sign of intestinal inflammation, but significant number of patients have asymptomatic intestinal inflammation, usually affecting ileum. Since most patients with SPA including BD are treated with NSAIDS. However, NSAID may play a role in aggravation or provocation of intestinal inflammation. Special attention to asymptomatic intestinal inflammation is needed, especially when NSAIDs are used for management of arthritic symptom in SpA. We experienced a case of BD which was complicated by a massive small bowel bleeding precipitated by NSAID use.

Magnetic resonance cholangiography(MRC) has emerged as an accurate and noninvasive modality for the evaluation of the biliary diseases. We performed this study to access the accuracy and efficacy of MRC for the diagnosis of obstructive biliary diseases. From March 1999 to September 2000, 87 patients with obstructive biliary diseases(24 malignant cancers, 55 cholelithiasis, 8 other obstructive biliary diseases) underwent MRC. MRC correctly revealed the obstructing biliary lesions and the cause of obstructions in 100% and 92% of the cases of malignancy respectively. The sensitivity and specificity of MRC were 94%, and 82% for extrahepatic bile duct stones, 94%, 100% for intrahepatic bile duct stones, and 84%, 100% for gallbladder stones retrospectively. In the other cause of biliary obstructions(3 benign biliary stricture, 2 acalculous cholecystitis, 2 xanthogranulomatous cho-lecystitis, and 1 extrinsic compression due to lymphadenopathy), MRC correctly showed the level of obstructions in all patients. But, MRC could not diagnose accurate causes of the obstruction except 3 patients(1 acalculous cholecystitis, 1 xanthogranulomatous cholecystitis, and 1 extrinsic compression due to lymphadenopathy). This study demonstrated that MRC was able to accurately identify the level and the cause of biliary obstructions in both malignancy and cholelithiasis. MRC was easily performed for a short duration and was a noninvasive diagnostic modality for assessing the biliary tree. Therefore, MRC was very efficacious clinically for the diagnosis of obstructive biliary diseases.

The aim of this study was to evaluate the clinicopathologic characteristics of the colorectal polyps in people under 50 years old. From January to August 2001, the colonoscopic finding and pathologic reports of 527 patients under 50 years old who underwent colonoscopy were reviewed retrospectively. The advanced polyp was defined as an adenoma more than 10mm in diameter or with the histology of villous or high grade dysplasia. Total 94 colonic polyps(17.8%) were analyzed. On age distribution, 65 cases(69.1%) were in forth decade, 25 cases(26.6%) in third decade. Abdominal pain(29.8%) was the most common cause of taking the colonoscopic examination followed by rectal bleeding(18.1%), asymptomatic screening(12.7%). Rectosigmoid area was the most common site of polyps in 63.8%. On the pathologic review, adenoma was found 55.1%, inflammatory polyp 38.5% and hyperplastic polyp 6.4%. Advanced adenomas were 17.9%(17/156) and adenomas with focal carcinomatous changes were 1.9%(3/156). Patients who had symptoms of abdominal pain or rectal bleeding, multiple polyps or familial history of colorectal cancer had a higher prevalence of advanced adenoma than that of non-advanced adenoma( This study showed that major symptoms of patients with advanced polyps under 50 years old were abdominal pain and rectal bleeding. The symptoms, multiplicity of polyp and family history were important indicator of advanced polyps. Further study was needed for reasonable indication and cost effectiveness for colonoscopic examination in young age people.

The aim of this study was to investigate the characteristics of colonic mucosal lesions by colonoscopy and for assessment of clinical features in patients with acute diarrhea. From March 2000 to August 2001, one hundred and ten patients with watery or bloody diarrhea lasting less than 14 days. The colonoscopic finding was assessed to extent of lesion(rectum, left, right and total colon) and severity of inflammation(mild ; erythema and edema, moderate ; exudates and blood coagula, severe ; hemorrhage and ulcer). Male was 60(54.5%) and median age was 43 years(range ; 15-84 years). The day of colonoscopy from symptom onset was 5 days(range 1-14 days). The causative food was flesh and meat, sea food and fish, and vegetable in order. Eight patient have history of travel including oversea. Pancolitis was the most common finding(46/110, 41.8%) and the normal colonoscopic finding was noted in eighteen cases(16.4%). The mild inflammation was 40(43.5%), moderate was 26(28.3%) and severe was 26(28.3%). The severity of inflammation was significantly correlated to the extent of lesion(p<0.05, r=0,655). The colonoscopy in acute infectious colitis was a useful to evaluate the extent of lesion and the severity of disease.

A case of massive intestinal bleeding from jejunal diverticulum is describe. A 62-year-old man was refered to our hospital because of melena and anemia. After admission, he showed massive hematochezia with unstable vital sign. Esophagogastroduodenocopy and colonoscopy, selective abdominal angiography, and RBC bleeding scanning were performed to seek the cause of the intestinal bleeding, but none of these studies revealed the source of bleeding. The examination of small bowel with methylcellulose showed multiple small jejunal diverticuli and a large diverticulum. Resection of the involved portion of jejunum was performed. On pathological examination, two mucosal loss lesions were detected, but ulcer or arteriovenous malformation were not seen in the resected jejunal diverticulum. The patient showed no more intestinal bleeding after operation. Although jejunal diverticuli are rare, the careful search for this complication in a patient with intestinal bleding is important.

Patients undergoing maintenance hemodialysis(HD) potentially have an increased risk of exposure to viral hepatitis. The reported prevalence of antiHCV in hemodialysis patients varied widely form 7.6-54% according to dialysis center and there were there were many reports that showed the correlation between the prevalence of antiHCV and duration of HD or transfusion amount. Fifty-four patients on regular hemodialysis at our hospital were evaluated for the presence of hepatitic C antibody(antiHCV) with the comparison of various parameters such as duration of HD, amount of transfusion, past history of hepatitis, serologic markers of hepatitis B and current liver function. AntiHCV using second-generation enzyme linked immunosorbant assay were found in six of 54HD patients(11.1%). Among six antiHCV(+) percent four patients were found to have HCV-RNA in their plasma detected by PCR. The percent of male patients were significantly higher in antiHCV(+) group(66.7 vs 31.3%, p<0.05). The positivity of antiHCV did not correlated with the duration of HD and amount of transfusion(p>0.05), but prevalence increased over 2 years (5.9% in 1991, 11.1% in 1993) and HBsAg prevalence remained unchanged(9.8% in 1991, 9.3% in 1993). Therefore, regular follow-up of liver function test and use of separate machine for antiHCV positive patients may be needed to prevent the transmission of the hepatitis C virus during the hemodialysis process itself.
