Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

optical trocar to create the pneumoperitoneum for bariatric surgery

The technique involves the use of 4 12 mm trocars. Pneumoperitoneum is induced by a 0° optical trocar and maintained at 15 mmHg. The first trocar is usually inserted along the left mid-clavicular line approximately 2 fingers from the costal arch, another trocar along the left axillary line, a third trocar 1 cm to the right of the midline, and the fourth trocar along the right mid-clavicular line. A 10 mm, 30 ° laparoscope is used.
