Official Title: The Effect in Wedge Resection and IVb/V Resection of the Liver for Gallbladder Cancer Operation: Prospective Randomized Controlled Trial
Brief Summary: The extent of hepatic resection for gallbladder cancer can be done from a wedge resection to 4b/5 bisegmentectomy. This study aims to compare the recurrence rates and survival rates between wedge resection group and bisegmentectomy group. Patients with T2 or T3 gallbladder cancer on preoperative CT exam or patients who were pathologically diagnosed as T2 or T3 gallbladder cancer after initial simple cholecystectomy were enrolled. All patients are randomly assigned to wedge resection or bisegmentectomy group. Number of patients in each group is 44. Primary endpoint is recurrence-free-survival rates and overall survival rates.
