Comparison of Harmonic Scalpel and Ligasure Devices in Laparoscopic Morbid Obesity Surgery
Comparison of harmonic scalpel and ligasure devices in laparoscopic morbid obesity surgery
 especially in gastric bypass surgery patients.
The investigators' department performs 150 gastric bypass surgeries annually. Surgeons use
