Laparoscopic surgery has been widely accepted as a feasible and safe treatment modality in many cancers of the gastrointestinal tract. However, most guidelines on gallbladder cancer (GBC) regard laparoscopic surgery as a contraindication, even for early GBC. This study aims to evaluate and compare recent surgical outcomes of laparoscopic and open surgery(More)
Bronchobiliary fistula (BBF) is a rare complication of radiofrequency ablation (RFA), in which there is abnormal communications between the biliary tract and the bronchial trees. Surgery should only be considered for BBF when non-invasive interventions have failed. In this report, we describe the surgical management for BBF when complicated by an abscess(More)
PURPOSE Metastasis to the pancreas is rare, and the benefit of resection for pancreatic metastasis is poorly defined. The aim of this study was to review our experiences of the operative management of metastasis to the pancreas. METHODS Between 1995 and 2009, 11 patients (8 men and 3 women; median age, 54 years) were admitted to our institution with a(More)
PURPOSE Attempt to identify the beneficial effects associated with surgical procedures on survival outcome of patients with recurrent cholangiocarcinoma. METHODS 921 patients diagnosed with cholangiocarcinoma underwent surgical resection with curative intent in a single institute during the last 15 years. Patients with recurrent disease were divided into(More)
Prediction of malignancy or invasiveness of branch duct type intraductal papillary mucinous neoplasm (Br-IPMN) is difficult, and proper treatment strategy has not been well established. The authors investigated the characteristics of Br-IPMN and explored its malignancy or invasiveness predicting factors to suggest a scoring formula for predicting pathologic(More)
BACKGROUND Biliary tract cancers (BTCs) are rare and heterogeneous group of tumors classified anatomically into intrahepatic and extrahepatic bile ducts and gallbladder adenocarcinomas. Patient-derived tumor cell (PDC) models with genome analysis can be a valuable platform to develop a method to overcome the clinical barrier on BTCs. MATERIAL AND METHODS(More)
We conducted a prospective genomic screening trial with high throughput sequencing and copy number variation (CNV) assay, and immunohistochemistry array in metastatic solid cancer patients. We used Ion AmpliSeq Cancer Hotspot Panel v2 and nCounter Copy Number Variation Assay (21 genes) to identify molecular targets for potential matched therapy. Metastatic(More)
PURPOSE Prognostic factors for distal bile duct cancer are contentious. This study was conducted to analyze the prognostic factors of distal bile duct cancer after surgery with the aim of identifying those associated with diminished survival. METHODS Two hundred forty-one patients who underwent pylorus-preserving pancreaticoduodenectomy (PPPD) or Whipple(More)
PURPOSE Some patients who undergo surgical resection of pancreatic cancer survive longer than other patients. The purpose of this study was to identify the factors that affect long-term survival after resection of histopathologically confirmed pancreatic ductal adenocarcinoma. METHODS A single-center, retrospective study was conducted among 164 patients(More)
