ABSCESS FORMATION DUE TO DROPPED GALLSTONE AFTER LAPAROSCOPIC CHOLECYSTECTOMY

Laparoscopic cholecystectomy is a popular treatment modality of sympto matic gallstones with decreased major complications and shortened hosp ital stay. Complications following laparoscopic cholecystectomy, most of them involving strictures of biliary tract have been well described in recent reports. However, there are only a few reported cases about dropped gallstones after the procedure, all of which were opaque and easily demonstrated with multiple imaging modalities. An unusual compl ication of laparoscopic cholecystectomy; abscess formation due to a dr opped non-opaque gallstone is described in which diagnosis was suggest ed with the combination of ultrasound and computed tomography findings and confirmed by surgery.
