Many weight loss surgeons prefer to perform laparoscopic procedures rather than open procedures. Laparoscopic gastric bypass procedures involve making five or six small incisions on the abdomen and inserting cameras into the body to view the internal tissues. Surgeons use thin instruments to perform the surgery.
Laparoscopic procedures are so popular because they carry less risk of complication during and after surgery. Open procedures involve cutting the abdomen open and operating directly on the tissues, exposing the internal tissues to open air. Patients undergoing laparoscopic procedures are less likely to experience hemorrhaging, and have less pain and shorter recovery periods after surgery.
