Right lumbar abscess containing a gallstone-an unexpected late complication of laparoscopic cholecystectomy.

During laparoscopic cholecystectomy, gallbladder perforation may occur leading to gallstone spillage and despite being rare, early or late complications may therefore develop. We report a case of a 79-year-old female, with a past medical history of a laparoscopic cholecystectomy 3 years earlier for symptomatic gallstones, admitted in the emergency department with a subcutaneous right lumbar abscess confirmed by computed tomography. Emergent abscess surgical drainage was performed and a gallstone was identified during saline lavage. Postoperative evolution was unremarkable and follow-up within a year was uneventful. Split gallstones due to gallbladder perforation during laparoscopic cholecystectomy should be retrieved in order to reduce future complications.
