Dropped gallstones due to accidental perforation of gallbladder wall during laparoscopic cholecystectomy are often encountered. However, dropped gallstones as nidus of infection with subsequent abscess formation is a rare complication of laparoscopic cholecystectomy (0.3%). Most of the reported cases of complicated dropped stones required open surgical drainage. Minimally invasive measures were less frequently employed. We report a case of dropped gallstones that were removed endoscopically through a percutaneous drainage tract.
