INTRODUCTION Management of the biliary ducts during liver resection is one of the most important challenges for hepatobiliary surgeons. Here, we report the case of a left hepatic trisectionectomy for hilar cholangiocarcinoma with a rare aberrant biliary duct of segment 5, which, to the best of our knowledge, has never been reported in previous literature. CASE PRESENTATION A 56-year-old Asian...

INTRODUCTION A single gallbladder with a double cystic duct is a very rare finding. In addition, few cases with this rare condition are preoperatively diagnosed. However, the preoperative confirmation or suspicion of this rare condition could facilitate safe laparoscopic cholecystectomy, which is a minimally invasive therapeutic modality for gallbladder disease. We herein present a case of gall...

BACKGROUNDS/AIMS In hepatocellular carcinoma (HCC), bile duct invasion occurs far more rarely than vascular invasion and is not well characterized. In addition, the pathologic finding of bile duct invasion is not considered an independent prognostic factor for HCC following surgery. In this study, we determined the characteristics of HCC with bile duct invasion, and assessed the clinical signif...

The factors influencing the migration of gall stones are ill understood. Altogether 331 patients undergoing cholecystectomy were studied prospectively. The diameters of the cystic and common bile ducts and of stones in the gall bladder and bile ducts were measured. Increasing pressure was applied to the freshly excised gall bladder in an attempt to evacuate stones through the cystic duct. Stone...

BACKGROUND Major bile duct injury is an important therapeutic problem that can be associated with simultaneous injury to the hepatic artery. Limited information exists regarding the course of patients who have combined bile duct and arterial injuries. OBJECTIVE To compare the management and outcome of isolated bile duct injuries with bile duct and hepatic artery injuries. PATIENTS AND METHO...

To learn more about the potential of neonatal porcine pancreatic duct and islet cells for xenotransplantation, the development of these cells when cultured as monolayers was evaluated. Immunostaining for islet hormones and cytokeratin-7 revealed that day eight monolayers consisted of approximately 70% duct cells and less than 10% beta cells. Using Ki-67 immunostaining as a proliferation marker,...

The bile duct system is a pathway of bile transportation from the liver to the intestine and plays a role of exocrine function of the liver. It consists of two different types of epithelial cells, hepatocytes and cholangiocytes. Anatomically as well as developmentally, the bile duct could be divided into intrahepatic bile duct (IHBD) and extrahepatic bile duct (EHBD; extrahepatic hepatic duct, ...

To describe the origin, course and termination of the thoracic duct in cats, eight adult healthy cats of both sexes and of different ages, were examined. Abdominal cavity was opened with a median incision under general anaesthesia. Then, Indian ink was injected into the lymph nodes of the abdominal cavity, and into the popliteal lymph nodes. After exsanguination by the conventional methods, the...

A 4-year-old male Japanese Shiba Inu presented with recurrent chylothorax. The thoracic duct was successfully imaged using computed tomography after the injection of an iodine contrast agent into the subcutaneous tissue surrounding the anus. The thoracic duct was successfully ligated and pericardectomy performed via an open thoracotomy. Pleural effusion improved but relapsed a week after the su...
