[Small bowel obstruction at the site of introduction of the trocar: an unusual complication of laparoscopy].

A 65 year old healthy female developed a small bowel obstruction after laparoscopic unroofing of a large, symptomatic, right renal cyst. After failure of conservative management, exploratory laparotomy revealed a very localized herniation of small intestine at a trocar site as suggested by CT scan. The hernia was reduced at the time of laparotomy and no bowel resection was necessary. The patient had an uneventful recovery. Although uncommon, bowel herniation at the site of trocar insertion should be recognized as part of the possible morbidity of laparoscopic surgery. The mechanism of development of such a complication and possible preventive measures are reviewed. A "preventive" fascial closure technique is suggested.
