The direct trocar technique: an alternative approach to abdominal entry for laparoscopy

The direct trocar technique is an alternative to Veress needle insertion and open laparoscopy for accessing the abdominal cavity for operative laparoscopy. We review our approach to abdominal entry in 1385 laparoscopies performed between September 1993 and June 2000 by our group at Stanford University Hospital, a tertiary Medical Center.

We performed a retrospective chart review of 1385 patients who underwent operative laparoscopy during the study years. The mode of abdominal entry, patient demographics, and complications were reviewed.

The transumbilical direct trocar entry method was used in 1223 patients. In 133 patients, the Veress needle insertion technique was used. Open laparoscopy was used in 22 patients. Three (0.21%) major complicadons occurred: 1 enterotomy, 1 omental herniation, and 1 bowel hemiation. One complication was related to primary access (0.072%) in a patient who had an open laparoscopy. She sustained an enterotomy during placement of the primary trocar. The bowel was repaired laparoscopically. No trocar-related injuries occurred among the 1223 patients in whom the direct trocar entry technique was used. One patient had an omental herniation and required a repeat laparoscopy on postoperative day 2. The second patient had a repeat laparoscopy on the 12th postoperative day to repair a bowel herniation. None of our patients required a laparotomy. No vascular injuries occurred.

Based on our experience, the direct trocar technique is a safe approach to abdominal entry for laparoscopic surgery.
