The authors describe an interesting complication after laparoscopic cholecystectomy. During a complicated operation perforation of a gallbladder, severely altered by inflammation, occurred and part of the concrements escaped into the peritoneal cavity. Several concrements were left in the abdominal cavity. After several weeks of a complicated postoperative development the concrements penetrated into the subcutaneous layer in the lumbar region and finally they were eliminated spontaneously. In the discussion the authors deal with complications of laparoscopic cholecystectomy.
