During minimally invasive (or laparoscopic) surgery, a small camera is inserted into the abdomen, and the surgeon views the procedure on a separate video monitor. This approach is considered less invasive because it replaces the need for one incision to open the abdomen.
Some studies suggest that patients having had laparoscopic weight loss surgery experienced less pain after surgery, resulting in easier breathing and lung function and higher overall oxygen levels. Other realized benefits included fewer wound complications such as infection or hernia, and patients returning more quickly to pre-surgical levels of activity. Minimally invasive surgery should only be performed by a specially-trained surgeon.
In some cases, minimally invasive surgery is not appropriate. Your surgeon will advise you as to which approach is best for you.
