MALIGNAT COLORECTAL OBSTRUCTION: PALLIATIVE ENDOSCOPIC TREATMENT WITH SELF-EXSPANDING METALLIC STENTS

Gallbladder carcinoma late metastases and incisional hernia at umbilical port site after laparoscopic cholecystectomy.

A potentially serious complication of laparoscopic cholecystectomy is the inadvertent dissemination of unsuspected gallbladder carcinoma. There are increasing reports of seeding of tumor at the trocar sites following laparoscopic cholecystectomy in patients with unexpected or inapparent gallbladder carcinoma. Although the mechanism of the abdominal wall recurrence is still unclear, laparoscopic handling of the tumor, perforation of the gallbladder, and extraction of the specimen without an endobag may be risk factors for the spreading of malignant cells. The Authors report the case of late development of umbilical metastasis after laparoscopic cholecystectomy; the presence of an incisional …

Xanthogranulomatous Cholecystitis

Summary Xanthogranulomatous cholecystitis (XC) is a chronic inflammatory lesion of the gallbladder histologically characterized by the presence of varying amounts of foamy histiocytes in the inflammatory infiltrate. In this study a review of 63 cases selected from 1207 surgically removed gallbladders is presented; the percentage found (5.2%) is slightly higher than that of previous reports showing that XC is less uncommon than generally believed. A detailed microscopic study is performed: the authors observed according to the histological features particularly the different patterns of distribution of the inflammatory infiltrate and postulate the existence of three subtypes of XC: multinodu…
