Hemosuccus Pancreaticus in the Era of Capsule Endoscopy and Double Balloon Enteroscopy Complicated by Multifocal Mycobacterium chelonae/abscessus Infection

Hemosuccus pancreaticus is a rare etiology of obscure gastrointestinal bleeding characterized by bleeding into the pancreatic duct. The diagnosis may be delayed for months to years, due to the episodic nature of bleeding and failure to consider the diagnosis. Patients often undergo multiple endoscopies and radiologic evaluations prior to diagnosis. Incidental gastrointestinal findings may lead to unnecessary endoscopic and surgical interventions. This report describes a patient with hemosuccus pancreaticus diagnosed in the era of video capsule endoscopy and double balloon enteroscopy, whose management was complicated by multifocal Mycobacteria chelonae/abscessus infection

Flowcharts for the diagnosis and treatment of acute cholangitis and cholecystitis: Tokyo Guidelines

Diagnostic and therapeutic strategies for acute biliary inflammation/ infection (acute cholangitis and acute cholecystitis), according to severity grade, have not yet been established in the world. Therefore we formulated flowcharts for the management of acute biliary inflammation/ infection in accordance with severity grade. For mild (grade I) acute cholangitis, medical treatment may be sufficient/appropriate. For moderate (grade II) acute cholangitis, early biliary drainage should be performed. For severe (grade III) acute cholangitis, appropriate organ support such as ventilatory/circulatory management is required. After hemodynamic stabilization is achieved, urgent endoscopic or percutaneous transhepatic biliary drainage should be performed. For patients with acute cholangitis of any grade of severity, treatment for the underlying etiology, including endoscopic, percutaneous, or surgical treatment should be performed after the patient's general condition has improved. For patients with mild (grade I) cholecystitis, early laparoscopic cholecystectomy is the preferred treatment. For patients with moderate (grade II) acute cholecystitis, early laparoscopic or open cholecystectomy is preferred. In patients with extensive local inflammation, elective cholecystectomy is recommended after initial management with percutaneous gallbladder drainage and/or cholecystostomy. For the patient with severe (grade III) acute cholecystitis, multiorgan support is a critical part of management. Biliary peritonitis due to perforation of the gallbladder is an indication for urgent cholecystectomy and/or drainage. Delayed elective cholecystectomy may be performed after initial treatment with gallbladder drainage and improvement of the patient's general medical condition. © Springer-Verlag Tokyo 2007.published_or_final_versio

An Experimental-Model for Laparoscopic Common Bile-Duct Exploration

The development of an effective and reliable technique for laparoscopic common bile duct exploration has been limited by the technical difficulty of the procedure and the lack of a suitable animal model with a bile duct diameter large enough to accommodate the fiberoptic choledochoscope and other instruments used for stone extraction. Short-term bile duct ligation in the dog provides a simple and reproducible animal model that enables the surgeon to gain experience with laparoscopic common bile duct exploration in a laboratory setting. This model will enable the surgeon to develop the technical skills necessary to perform laparoscopic common bile duct exploration. In addition, the model may facilitate the development and refinement of new techniques and instruments that will facilitate laparoscopic common bile duct exploration in the clinical setting
