Bowel injuries during laparoscopy. Gross anatomy and histology

Abstract

Bowel injuries during laparoscopy can result from either electrical damage or direct trauma. When electrocoagulation is used with laparoscopy, it is frequently assumed that any bowel injury is from that source. That assumption might not be accurate. In animal studies we evaluated the histologic characteristics of both electrical and traumatic bowel injuries. A consistent difference in injury pattern, both gross and microscopic, was noted. With a high degree of accuracy, those histologic and gross characteristics can be used to distinguish traumatic from electrical injuries following operative laparoscopy.
