In a male after laparoscopic cholecystectomy, the specimen is sent for histopathology which shows carcinoma gallbladder stage T1a. What is the most appropriate management in this patient?

With the finding of carcinoma following cholecystectomy, subsequent treatment depends on the depth of penetration of the gallbladder wall and surgical margins.With T1a lesions, in which the carcinoma penetrates the lamina propria but does not invade the muscle layer, simple cholecystectomy should suffice for therapy.
