Should the extrahepatic bile duct be resected or preserved in R0 radical surgery for advanced gallbladder carcinoma? Results of a Japanese Society of Biliary Surgery Survey: a multicenter study.

Purpose: We assessed the significance of an extra bile duct resection by comparing the survival of patients with advanced gallbladder carcinoma who had resected bile ducts with those who had preserved bile ducts. A radical cholecystectomy that includes extra bile duct resections has been performed without any clear evidence of whether an extra bile duct resection is preventive or curative.

Methods: We conducted a questionnaire survey among clinicians who belonged to the 114 member institutions of the Japanese Society of Biliary Surgery.

Hepatic resection in 485 R0 pT2 and pT3 cases of advanced carcinoma of the gallbladder: results of a Japanese Society of Biliary Surgery survey--a multicenter study.

Purpose: We conducted this study to evaluate the optimal hepatic resection for pT2 and pT3 advanced carcinoma of the gallbladder without invasion of the hepatoduodenal ligament.

Methods: We conducted a questionnaire survey regarding 4,243 cases of carcinoma of the gallbladder treated during the recent 10-year period at 112 institutions belonging to the Japanese Society of Biliary Surgery. The questionnaires included questions on preoperative-diagnosis, complications, treatment, and surgical treatment, procedures of resection, surgical result, path histological findings, mode, and site of recurrence, additional post-operative treatment.
