Optical Trocar to Create the Pneumoperitoneum in Bariatric Patients

Optical Trocar to Facilitate the Pneumoperitoneum Creation in Bariatric Patients: Our Experience and Systematic Review

Laparoscopic bariatric surgery are becoming the most used procedure to treat the obesity. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at the left hypocondrium. The aim of this study is to systematically evaluate all published data existing in the literature to analyze the safety of optical trocars in patients undergoing bariatric surgery and to compare these data with our experiences.

In this study we analyze data existing in the literature about the use of the optical trocars in patients undergoing bariatric surgery and we compare these data with our experiences.

Establishing pneumoperitoneum is classically performed using a Veress needle or the open Hasson technique, but obesity presents its own challenges when using these techniques, including thickened abdominal wall, variable anatomical landmarks, difficult and time-consuming dissection, air leak, inadequate pneumoperitoneum, subcutaneous emphysema, and difficulty with fascial closure
