There are several options for Obesity Surgery, but basically, there are three available procedures:
• Restrictive Procedures: it consists in promoting only a restriction in the alimentary volume ingestion by a surgical confection of a new gastric reservoir, in general, with a capacity of 50ml. Ex: Sleeve Gastrectomy and Adjustable Gastric Band.
• Malabsorption Procedures: it consists of the surgical exclusion of a segment of the intestine from the alimentary path. The stomach may or may not be kept intact. Ex: Duodenal Switch.
• Mixed procedures: are considered gold standard in the treatment of obesity, since these surgeries associate restriction and malabsorption procedures simultaneously. Ex: Chapel Surgery or Bypass Y of Roux.
For any surgical procedure, there are two main access routes to be defined by the surgeon:
• Open surgery:
An open procedure consists in performing a long incision in the abdomen allowing the surgeon to have access to the surgical site. Open procedures for the Surgery of Obesity use the same principles of Laparoscopic Surgery. Therefore, they produce similar weight loss. This approach is indicated by our staff only in very adverse clinical situations, such as in the presence of an extremely fatty and enlarged liver, giant incisional hernias, and others.
• Video-laparoscopic approach:
In this approach the surgeon inserts a small camera into the abdomen through small holes in the abdominal wall, allowing the surgeon to conduct and watch the surgery through a video monitor. Laparoscopic Procedures for the Surgery of Obesity use the same principles of Open Surgery approach. Therefore, they produce similar weight loss. It is the access route used in 99% of the surgeries performed by our team.
In comparison with Open Surgery, some benefits of Laparoscopic Surgery include:
• Less post-operative pain;
• Less wound infection (incisions);
• Minor occurrence of incisional hernias;
• Rapid recovery and return to activity.
