A Case of Successful Endoscopic Management of Afferent Loop Leakages by Using Hemoclips and a Detachable Snare / 대한소화기내시경학회지

There are many complications following gastrectomy and one of the most frequent complications is anastomosis site leakage. Postoperative leakage is a serious complication in patients after they undergo gastric surgery. It can lead to the progressive deterioration in the patient's condition and quality of life and the mortality rate is nearly 60%. We encountered a case of a 75 year-old man who had the leakage of the jejunal end of the Roux limb after total gastrectomy. We performed treatment of the leakage endoscopic clipping and detachable snaring. Hemoclips were fixed at the margin of both sides of the lesion. A detachable snare was used to bind both hemoclips, so the interval was made narrow. After snare binding, five hemoclips were used for final closure of the small interval. After treatment, the leakage of the afferent loop end was completely stopped. He resumed an oral intake and was discharged without complications.

Obstructive Jaundice due to Biliary Cast Syndrome Followed by Orthotopic Liver Transplantation / 대한소화기학회지

Biliary complication occurs in 6-34% of all liver transplant patients. Although bile leaks and strictures are relatively common, other biliary complications such as T-tube leak, choledocholithiasis, and biliary cast syndrome can also be observed. The biliary cast syndrome describes the presence of casts causing obstruction with its resultant sequelae of biliary infection, hepatocyte damage secondary to bile stasis and ductal damage, all contributing to cholangiopathy. Because the exact timing of cast formation after orthotopic liver transplantation is not consistent, it is difficult to define the true incidence of biliary cast syndrome without long-term follow-up data. Proposed etiological mechanisms include acute cellular rejection, prolongation of cold ischemic time, infection, biliary drainage tubes, and biliary obstruction. The diagnosis of biliary cast syndrome is usually confirmed by endoscopic retrograde cholangiopancreatography. There have been few published articles about biliary casts in Korea. Herein, we report a case of biliary cast syndrome followed by orthotopic liver transplantation.

Preoperatively Diagnosed Asymptomatic Early Extrahepatic Bile Duct Cancer / 대한소화기내시경학회지

Cholangiocarcinoma is usually diagnosed at the advanced stage because early symptoms and signs are relatively infrequent. The preoperative diagnosis of early extrahepatic bile duct cancer in common bile duct is uncommon. Also, an extrahepatic bile duct cancer arising from the lower portion of the common bile duct is usually papillary and rarely nodular or sclerosing. We decribe a case, preoperatively diagnosed as early extrahepatic bile duct cancer in lower portion of common bile duct, nodular type on endoscopic retrograde cholangiography. It was incidentally detected by the slight elevation of gamma-glutamyl transpeptidase without any symptoms. An endoscopic retrograde cholangiography showed abrupt narrowing of the intrapancreatic portion of the common bile duct with irregular and nodular filling defect. The lesion was confined to mucosa on the endoscopic ultrasonography. This patient was diagnosed as early extrahepatic bile duct cancer and underwent Whipple's operation. A histopathologic examination of resected specimen revealed to be moderately differentiated adenocarcinoma at stage 1 (T1N0Mo) in the extrahepatic bile duct.
