Experience with the optical access trocar for safe and rapid entry in the performance of laparoscopic gastric bypass



In laparoscopic surgery, serious complications caused by the blind insertion of trocars are well known. The open technique is compromised by the leakage of carbon dioxide and can also be time consuming, especially in morbidly obese patients. Our aim was to determine whether the optical access trocar can be used to establish a safe and rapid entry during laparoscopic gastric bypass.


The data on a single surgeon’s experience with 370 laparoscopic gastric bypass procedures during a 4-year period were reviewed. The Optiview trocar was used for all except the initial 21 patients. The entry time for the optical trocar was measured in 10 patients.


Of the 370 patients undergoing laparoscopic gastric bypass from November 2000 to September 2004, the initial 21 were treated using the standard Veress needle to create the pneumoperitoneum. The next 22 were treated using the Veress needle to create the pneumoperitoneum, followed by insertion of the optical access trocar in the left upper quadrant as the initial trocar. From this point to the present, the optical access trocar has been inserted without the use of a Veress needle. There have been no trocar-related bowel or vascular injuries in the entire series. The mean optical trocar insertion time was 28 ± 1.2 s.


This is the first laparoscopic gastric bypass series to report the results of its experience with the optical access trocar. This device provides a safe and rapid technique for placement of the initial trocar for laparoscopic gastric bypass. Insertion of the optical trocar with a 10-mm laparoscope into the left upper quadrant is our procedure of choice for obtaining the pneumoperitoneum in this patient population.
