Laparoscopic Access: Direct Trocar Insertion Versus Open Technique.

INTRODUCTION

Creation of pneumoperitoneum and laparoscopic entry into the abdominal cavity are crucial initial steps of laparoscopic surgery and associated with bowel and major vessel injuries. Various methods have been described in literature such as Veress needle, open access technique (OAT), direct trocar insertion (DTI), and optical port. There is no consensus on the safest method of gaining access to the peritoneal cavity to create a pneumoperitoneum. DTI technique appears to be not well accepted by many due to the fear of causing injuries as it is a blind procedure.

OBJECTIVE

To compare the outcome of DTI in terms of feasibility and complications with a well-established and widely practiced OAT for a laparoscopic procedure.

MATERIALS AND METHODS

Nine hundred fifty-five participants were randomized to be in either of the two groups, that is, Group "A" for DTI and Group "B" for OAT. The primary endpoint was major complications (bowel, major vessel, and solid organ injury) and the secondary endpoint was port access time and minor complications directly related to access. Patients were assessed on the first postoperative day, at the time of discharge, 3 months, 6 months, and a year after discharge, for complications.

RESULTS

There was no statistical difference in major complications between DTI and OAT groups, however, DTI was found to be superior to OAT in terms of port access time (P = .01), umbilical port-site hernia, port-site infection, and port-site pain (P = .01).

CONCLUSION

This study further strengthens the literature on DTI being a good and safe technique of laparoscopic access. The technique of DTI is still underutilized and needs to be adopted by surgeons without fear.
