About

Comparison of harmonic scalpel and ligasure devices in laparoscopic morbid obesity surgery especially in gastric bypass surgery patients.

Full description

The investigators' department performs 150 gastric bypass surgeries annually. Surgeons use both harmonic scalpel and ligasure sealing device in cases. Aim is to compare both of these devices over coming each other. Benefits ease of these devices are compared.
