title: Superficial elevated-type early gallbladder carcinoma treated by laparoscopic cholecystectomy.
abstract: A 60-year-old woman was admitted to our department for detailed examination of a polypoid lesions of the gallbladder detected at the time of a mass survey by ultrasound. Endoscopic ultrasonography (EUS) demonstrated a broad-based mass lesion, about 10 mm in size, with an irregular surface, at the peritoneal side of the body of the gallbladder. The layer structure of the gallbladder wall had not been destroyed by the mass. Computed tomography showed no direct invasion of the liver or other evidence of metastasis. Type-IIa (superficial elevated-type) early gallbladder cancer was suspected and laparoscopic cholecystectomy was performed. Histologically, the tumor proved to be a papillo-tubular adenocarcinoma, 9 x 8 mm in size, confined to the mucosa and without lymphatic permeation, vascular involvement, perineural invasion, or other signs of metastasis. Laparoscopic cholecystectomy for gallbladder cancer can be indicated only when a lesion is a pedunculated protruded-type (type-Ip) cancer, or a broad-based cancer 10 mm or less in size located on the peritoneal side with no destruction of the layer structure of the wall demonstrated by EUS. This strategy is justified only with precise evaluation of the lesion by EUS.
