A Rare Pathology of Difficult Laparoscopic Cholecystectomy: Xanthogranulomatous Cholecystitis.
J Coll Physicians Surg Pak Jan ;28(4):330-1.

Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory condition of the gallbladder (GB). Preoperatively, it is a diagnostic challenge. One thousand and seventy-nine laparoscopic cholecystectomy (LC) patients from September 2012 to June 2015 were retrospectively reviewed. Fourteen patients were identified with XGC. An analysis was carried out on this group of patients looking at postoperative pathology results, preoperative radiology, operative findings and outcome. The overall frequency of XGC was 1.3%. A thick walled GB was found in 11 patients on preoperative imaging. Retrospectively suggestive feature thick gallbladder walls with low attenuation mural nodules. No suspicion of cancer was demonstrated in the final histology or preoperatively. Five cases (36%) perforated intraoperatively. Although all were surgically challenging, no conversions to open were performed. The perforation risk could be higher. A difficult cholecystectomy should alert a surgeon to consider XGC as a diagnosis. Contrary to the popular belief, XGC was found to be difficult to differentiate from infection rather than malignancy.
