Electrosurgical Injuries in Gynecologic Laparoscopy

We reviewed the 396 operative laparoscopies performed from March 1994 to March 1996 to determine the numbers and causes of electrical injuries. Electrical injuries were reported in four (1.01%) patients. Capacitive coupling induced by a laparoscope inserted through a conductive cannula sleeve with a nonconductive collar caused two bowel injuries that required laparotomy. Insulation failure of an electric cable resulted in a skin burn. A small surface contact area of a cannula sleeve being pulled out of the abdominal wall led to a surface burn in the abdominal wall. Lack of knowledge and insufficient attention on the part of laparoscopic surgeons and operating room personnel may result in electrosurgical accidents.
