抄録 <p> Endoscopic biopsy is an important tool for histological diagnosis of lesions residing in gastrointestinal tracts. However, it is less useful in submucosal lesions due to the existence of normal overlying mucosa. We developed a new and safe technique for the diagnosis of submucosal tumor using Stiegmann-Goff endoscopic ligator. After removing surface mucosa to expose submucosal tissue by this method, conventional secured histological diagnosis could be performed. To determine definitive histological diagnosis, this technique is useful as well as Endoscopic Ultrasound (EUS) with fine needle aspiration biopsy and other modalities.</p>

抄録 <p>A 54-year-old woman presented a massive hematochezia 7 days after sigmoidectomy. Repeated colonoscopy and angiography failed to locate the site of bleeding and Hartman's operation was performed. Rebleeding from the rectum on the day of operation occurred and pulsate arterial bleeding with minimal surrounding ulcer 1 cm above the pectinate line was observed. Screlotherapy with ethanol and electro coagulation was successfully performed to achieve permanent hemostasis. The importance of detailed rectal examination and an awareness of this clinical entity in life-threatening lower intestinal bleeding is discussed.</p>

抄録 <p>Bile duct injury can occur more frequently during laparoscopic cholecystectomy than in open cholecystectomy. Three cases of common bile or hepatic duct injuries occurred in a series of eighty laparoscopic cholecystectomies; In case 1, the common bile duct was misidentified as the cystic duct. In case 2, bile peritonitis occurred on the fourth postoperative day caused by necrosis of the common hepatic duct involving the cautery surrounding it. In case 3, a bile leak occurred due to an incision at the confluence of the cystic and common duct. Dissection of the cystic duct at the infundibulum of the gallbladder, blunt dissection of the Calot's triangle, the handling of clips with special attention for safety were thought to be necessary in order to lower the risk of bile duct injury. Preoperative endoscopic retrograde cholangiography (ERCP) is recommended to avoid bile duct injury.</p>

抄録 <p>We report a method of endoscopic retrograde sphincterotomy in patients in whom the optimal viewing of the papilla of Vater is hardly obtained. Percutaneous transhepatic cholangiodrainage (PTCD)-tube is placed under ultrasonographic guidance. PTCD-tube coming out of the papilla of Vater is observed by the endoscope and the guide wire inside the shpincterotome is inserted into the PTCD-tube. Sphincterotome is advanced into the common bile duct by the guidance of the guide wire and PTCD-tube. Sphincterotomy is performed in a usual fashion. Two patients with previous history of gastrectomy underwent this procedure with successful results. This method should be tried when usual method of EST is difficult and unsuccessful.</p>

抄録 <p>We experienced a patient with traumatic neuroma of the gallbladder with no history of gallbladder surgery or cholelithiasis. A 74-year-old man was referred to our department after a gallbladder tumor was incidentally discovered during a preoperative screening examination for prostate hypertrophy. Ultrasonography, MRI, CT and endoscopic retrograde cholangiography revealed a protuberant lesion of the gallbladder. Laparoscopic cholecystectomy was attempted but adhesion between the liver and duodenum forced us to convert to open laparotomy. Cholecystectomy and adjacent liver tissue resection was performed. Diagnosis was made by frozen histology during operation. It revealed no malignancy. Postoperative pathological examination revealed traumatic neuroma associated with inflammation. To our knowledge, this is the first reported case of gallbladder neuroma without a history of gallstones or surgery in the English and Japanese literature since 1980. This traumatic neuroma should be considered in a differential diagnosis in treating gallbladder neoplasm, even in the absence of an operative history or cholelithiasis.</p>
