Abstract: Abstract
An unusual anamoly of the extrahepatic bitiary system is reported in which the common hepatic duct was found to enter the gallbladder, whereas the cystic duct drained the entire biliarysystem into the duodenum. Excision of the gallbladder and cystic duct and a roux-en-Y hepaticojejunostomy was performed. Identification and treatment options of this rare anomaly are briefly discussed.
Abstract: Post-endoscopic retrograde cholangiopancreatography (ERCP) perforation usually resolves conservatively; however, intervention is sometimes needed, and there is a paucity of literature regarding the best management approach. We evaluated our experience of managing post-ERCP perforations to help define the role of surgery with percutaneous drainage (PCD).
Abstract: Varices of the colon are a rare cause of lower gastrointestinal bleeding, usually associated with portal hypertension due to liver cirrhosis or other causes of portal venous obstruction. Idiopathic colonic varices are extremely rare. Recognition of this condition is important as idiopathic colonic varices may be a cause of recurrent lower gastrointestinal bleeding.

Introduction: In an attempt to further enhance the benefits of cosmesis and reduced morbidity of minimally invasive surgery, single-port (incision) laparoscopic surgery (SPS) has emerged as a bridge between conventional laparoscopy and natural orifice transluminal endoscopic surgery. As the expertise and instrumentation required are an extension of standard laparoscopic techniques, SPS has been adapted for a variety of procedures and specialties in a short span of time.
Discussion: In this article, we discuss the various SPS techniques, as well as the new devices and instrumentation available for facilitating SPS. We also review current applications reported for SPS in various surgical specialties. We present a comprehensive review of the potential benefits, limitations and risks of these novel techniques.
Conclusion: Initial reports have demonstrated the technical feasibility and safety of SPS for a wide range of surgical applications. With specialized instrumentation and refinement of technique, its role will increase in coming years. Future work is necessary to improve existing instrumentation, to increase clinical experience and to assess the benefits of this surgical approach.
Abstract: Xanthogranulomatous cholecystitis (XGC) is a benign, invasive variant of chronic cholecystitis. Invasion of common bile duct (CBD), termed as xanthogranulomatous choledochitis, may mimic malignancy. We describe clinico-pathological features and management of xanthogranulomatous inflammatory biliary strictures.
Abstract: This paper highlights the etiology, diagnosis, management and outcome in nine unusual cases of extrahepatic biliary obstruction in children. Extrahepatic biliary atresia and choledochal cyst constituted 127 out of 136 (93%) cases of all pediatric surgical biliary disorders managed between March 2000 and February 2007 at the reporting centre. However, nine children (aged 1.5-15 years) presented with uncommon causes like (1) idiopathic benign non-traumatic inflammatory stricture (n = 3), (2) idiopathic fibrosing chronic pancreatitis (n = 2), (3) post-cholecystectomy type 4 benign biliary stricture (n = 1), (4) post-acute pancreatitis pseudo-cyst of pancreas (n = 1), (5) non-Hodgkin's lymphoma (NHL) with extramural common bile duct compression and gall bladder perforation (n = 1), and (6) Langerhan cell histiocytosis (LCH, n = 1). The clinical features and the diagnostic work up of each group are discussed. A preoperative endoscopic/percutaneous biliary drainage was required in four children because of cholangitis at presentation. A biliary-enteric anastomosis was performed for all seven children in groups (1)-(4). The patients with NHL and LCH were referred for chemotherapy after establishing tissue diagnosis at laparotomy. With a follow-up period of 3 months to 7 years, seven children (with the exception of patients with NHL and LCH) are currently anicteric. This paper draws attention to some infrequently discussed causes of extrahepatic biliary obstruction in children. The management entails a carefully planned combination of endoscopic interventions, interventional radiology and surgery. The outcome in benign cases is usually satisfactory.
Abstract: The purpose of this study is to classify biliary atresia (BA) with a "cyst at porta" according to the cholangiographic anatomy and to define management strategy and outcome in each group. A cyst at porta was identified in 13 of 58 babies (22.4%) with BA at first presentation. The cholangiographic anatomy was classified as; Group A (n = 7), type III BA with extrahepatic cyst; Group B (n = 2), type I or II BA with extrahepatic biliary cyst; and Group C (n = 4), type I or II BA with both extrahepatic and intrahepatic biliary cysts. The remaining 45 patients were comprised of type III BA without a cyst. A Kasai's portoenterostomy (PE) was performed for all Group A patients. Groups B and C were treated by hepaticojejunostomy (n = 5) or portoenterostomy (n = 1). All 45 patients with type III BA without a cyst were treated by a Kasai's PE. The median age at surgery was 92 days (ranges 28-342 days). There were three early post-operative deaths, all in patients with type III BA without cyst. Overall 18/55 (32.7%) patients achieved a jaundice free state. In Group A, 5/7 (71.4%) patients had bile flow, 2/7 (28.6%) are anicteric and 2/7(28.6%) had 1-2 episodes of post-operative cholangitis. In Group B, both patients are anicteric and none had post-operative cholangitis. In Group C, all four babies had bile flow but, significant morbidity because of recurrent severe cholangitis. Only one patient reached a jaundice free state. Of the remaining 42 patients with type III BA without a cyst, 27 (64.3%) had bile flow, 13 (31%) became jaundice free and 14 (33.3%) have had 1-2 episodes of post-operative cholangitis. In conclusion, thirteen of 58 (22.4%) babies with BA had a "cyst at porta" at first presentation in this series. The outcome was most satisfactory in type I BA without intrahepatic cystic dilatation (Group B) in terms of achieving a jaundice free state and freedom from recurrent cholangitis. However, intrahepatic biliary cysts (Group C) were associated with recurrent severe cholangitis and a poor eventual outcome despite a good initial bile flow. The outcome in type III BA with extrahepatic cyst was comparable to type III BA without cyst.
