Recurrent abdominal pain post appendectomy--a rare case.

Right iliac fossa pain in young adults who have previously had an appendicectomy represents a diagnostic challenge. In such cases it is important to review the histology of the appendix and the previous operation notes. The appendix stump, if left long following an appendectomy, can result in chronic appendicitis of the stump, or it can rarely develop into a mucocele. This case report describes a patient with an appendix stump mucocele who presented with chronic pain under the right iliac fossa incision and was successfully treated by laparoscopic resection.
