Persistent port-site sinus in a patient after laparoscopic cholecystectomy:watch out for gallbladder tuberculosis

BACKGROUND:The gallbladder is rarely affected by mycobacterium tuberculosis.The diagnosis of gallbladder tuberculosis is often not suspected prior to surgery or biopsy.METHOD:A young female patient underwent laparoscopic cholecystectomy but presented with a persistently discharging sinus from the port site.RESULTS:The gallbladder biopsy revealed granulomas typical of chronic granulomatous tuberculosis.The condition of the patient was improved by antitubercular treatment.CONCLUSIONS:Presentation of gallbladder tuberculosis as a persistent discharging sinus at the port site in a patient who has undergone a laparoscopic cholecystectomy is extremely rare.The diagnosis was reached by histopathology only.The rarity of the presentation prompted us to report the case.
