Comparison of Various Endoscopic Injection Therapy and Hemoclipping for Bleeding Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND/AIMS: Widely practiced endoscopic methods for hemastasis of bleeding peptic ulcer include thermal application (laser, heater probe) and local injection (epi- nephrine, fibrine-glue or various sclerosing agents). Studies evaluating these modalities have presented high success rates for achieving initial hemostasis. Recently, endoscopic hemoclipping is considered to be a safe and effective hemostatic method for upper gas- trointestinal bleeding. The aim of this study was to compare various hemostatic modalities for bleeding peptic ulcer. METHODS: Over a three year period between June 1994 and October 1997, a total of 133 patients with bleeding peptic ulcer were included in this study, We have conducted clinical trials and a retrospective analysis. All of the patients we selected had either active bleeding or a nonbleeding visible vessel on endoscopy. Endoscopy was performed on an emergency basis within 12 hours of hospital arrival.

Two Cases of Villous Adenoma of the Common Bile Duct: Endoscopic Diagnosis and Treatment / 대한소화기내시경학회지

Villous adenomas of the common bile duct are rare and accordingly it is difficult to render a firm preoperative diagnosis. They are the unusual cause of bile duct obstruction and can mimic malignant extrahepatic biliary tumors or stones. Until recently, only a few cases had been reported in the medical literature. Although some authors advocate open surgical excision, especially with recurrence or carcinomatous change, an endoscopic resection of a distal common bile duct adenoma is a viable alternative for those patients considered poor surgical risks. We present two cases of villous adenoma of the common bile duct diagnosed by an endoscopic biopsy and endoscopically resected, with review of the relevant literature on the subject.
