A New Laparoscopic Entry Point in Patients With Previous Laparotomy: A Prospective Comparative Study

Abstract

Introduction: Intraperitoneal access and establishing pneumoperitoneum for laparoscopy is a critical step especially in patients who underwent previous laparotomy due to the higher risk of visceral or vascular injuries. In this study, we propose a new entry point for safe laparoscopic access in cases having previous laparotomy. Materials and Methods: This is a prospective controlled randomized trial conducted between January 2016 and January 2022 in Ain Shams University Hospitals. It included 232 patients who underwent laparoscopic procedures after previous laparotomy. They were randomly divided into 2 equal groups. In group 1, laparoscopic access was carried out by an optical trocar through the new point situated in the subxiphoid region 1 cm below the costal margin and centered 2.5 cm from the midline on either side. In group 2, laparoscopic access was performed by an optical subumbilical trocar after Verres needle insufflation in Palmer point. The primary end points were success and safety of entry, measured by the number of entry attempts and the incidence of bowel and vascular injuries. The secondary end point was the entry time. Results: In group 1, safe entry into the abdomen was achieved without visceral or vascular injury. In the 3 cases, minor liver injuries occurred. In group 2, 2 major vascular injuries and 5 bowel injuries occurred. There was a significant difference in procedure time (55±7.2 s in group 1 vs. 192±11.6 s in group 2). Conclusion: The suggested entry point is fast, safe, and reliable in patients having previous laparotomy.
