A vertical or transverse umbilical incision was appropriately widened enough (1.0-1.5 cm) for the trocar to be inserted without undue resistance from the skin so that the trocar passed through the fascia and the peritoneum with ease.

Cosmetic outcomes of infraumbilical, supraumbilical, and transumbilical entry routes in laparoscopic surgery

Laparoscopic abdominal surgery requires the implementation of successful pneumoperitoneum.1 In vast majority of patients, more than half of all complications happen at the time of entry and a great majority of these occur during the insertion of the primary umbilical trocar.2 To address this issue, various techniques have evolved to gain access to the peritoneal cavity.

The percutaneous system has an outer diameter of 2.3 mm, integrated needle tips that facilitate insertion without a trocar, and a selection of integrated graspers (e.g., a miniature clutch or alligator) that open up to 12.5 mm and can be advanced and retracted through the cannula.

While Lap surgery itself is minimally invasive, "herniation", or protrusion of abdominal tissue through the port site after closure (commonly referred to as "trocar site hernia", or "TSH", among doctors), can lead to morbidity due to small bowel strangulation, for example, or nerve and vessel entrapment, resulting in infection, bleeding and pain.
