Background/Aims:Endoscopic retrieval of large common bile duct (CBD) stones is often difficult in patients who have undergone Billroth II gastrectomy, as anatomic alterations may present technical barriers to successful cannulation and increase procedure-related complications. Endoscopic papillary large balloon dilation (EPLBD) can be an alternative technique for the removal of difficult stones. Accordingly, the aim of this study was to evaluate the safety and effectiveness of EPLBD for CBD stone extraction in patients with Billroth II gastrectomy.Materials and Methods:From July 2006 to November 2011, 30 patients who underwent EPLBD with limited endoscopic sphincterotomy (EPLBD + ES) or EPLBD alone for the treatment of large CBD stones (≥10 mm) after Billroth II gastrectomy were retrospectively reviewed. A large balloon dilator (12-18 mm) was used to dilate the ampullary orifice.Results:Selective cannulation was successful in 25 patients (83.3%) with a standard catheter. Of the 30 subjects, EPLBD + ES was performed in 19 and EPLBD alone in 11. The mean bile duct diameter was 17.7 ± 4.3 mm (range, 11-31 mm), and mean size of balloon dilation was 14.5 ± 2.6 mm (range, 12-18 mm). Stone removal was successfully completed in 29 patients (96.7%). Successful stone retrieval during the first session was achieved in 27 patients (90.0%). Two cases (6.7%) of mild pancreatitis responded to conservative treatment, and no perforation or mortality was encountered.Conclusions:EPLBD with or without needle knife (NK) sphincterotomy seems to be a safe and feasible modality for CBD stone retrieval in patients with prior Billroth II gastrectomy.
The use of non-absorbable suture materials for cystic duct ligation after cholecystectomy can expose patients to the risk of recurrent stone formation in the common bile duct (CBD). However, in Korea suture materials have rarely been found to act as a nidus for common bile duct calculus formation. Recently, we experienced a case in which suture material, that had migrated from a previous cholecystectomy site into the CBD, probably served as a nidus for common bile duct stone formation. The stone was confirmed by endoscopic retrograde cholangiopancreatography (ERCP) and removed successfully using a basket. The authors report a case of surgical suture migration and discuss its subsequent role as a stone forming nucleus within the CBD in a patient who underwent open cholecystectomy; and include a review of the literature.
The incidence of hepatocellular carcinoma presenting as obstructive jaundice is 0.7∼9%. The mechanisms of obstructive jaundice include bile duct invasion by tumor, tumor thrombi, blood clots, direct bile duct compression by tumor, and intraductal tumor growth. We report a rare case of hepatocellular carcinoma with intraductal growth. A 46-year-old woman was admitted due to colicky right upper abdominal pain and jaundice for 4 days. Computed tomography showed dilatation of the left intrahepatic duct, and endoscopic retrograde cholangiography showed a filling defect in the left main intrahepatic duct. We performed a left lobectomy with a Roux-en-Y hepaticojejunostomy. The tumor was diagnosed as a hepatocellular carcinoma with intraductal growth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
