Bariatric Surgery – How Does Weight Loss Surgery Work? – Part II
During a typical gastric bypass, the surgeon would reconnect the duodenum along with the intestinal tract at a site nearly twenty to forty inches below the newly created stomach aperture that assists in the pancreatic juices emptying in the intestines, however they do not combine with the food as quickly as they would earlier do. There are few solely malabsorptive surgeries being carried out in bariatric surgery presently.
A gastric bypass is deemed the gold standard and causes nearly 85% excess weight loss and aids in resolution of the diabetes early on.
Biliopancreatic Diversion (BPD) and Duodenal Switch (DS) – This is one of the state-of-the-art techniques tagged as malabsorptive. BPD is ideally not suggested to those patients who find it a challenge to meet up with daily dietetic requirements of high protein and multivitamins.
The operation is much alike gastric bypass but with some major variations. Firstly, it comprises the total removal of a major portion of the stomach and not just a mere seal up of a section of it. Secondly, pancreatic juices come in near the concluding part of the small intestine near the colon (large intestines).
Combo of Restrictive and Malabsorptive Surgery – This involves a Roux-en-Y gastric bypass. During the procedure the stomach and the initial part of the intestines are bypassed by creating a small pouch with the aid of staplers and a loop of the intestine is connected to it. This leads to restraint in food consumption alongside nutrient malabsorption.
Common complications after Laparoscopic Bariatric Surgery include:
- Chances of leakage from the anastomotic location.
- Obstruction in the intestines.
- DVT or Deep Vein Thrombosis and pulmonary embolism.
- Post-surgery infections like wound infections and operative site infections like trocar-site infections.
All weight loss surgery involves the usage of general anesthesia and a short period of hospitalisation. Laparascopic technique is a minimally invasive procedure leaving lesser and smaller sized scars as compared to open surgery and has lesser noted complications and faster recuperation rate. 90% of gastric bypasses are carried out in this manner.
Following surgery, the digestive system might seem quite tender. In the initial few days after surgery, a liquid diet is given to the patient, followed gradually by thicker consistency liquids after few days. In the following 3-4 weeks, many small portion-sized foods in puree or liquid form are administered. In the second month, eating soft textured, moistened food is allowed involving chewing. In third month, one could start with a regular dietary intake, though one would not be able to eat big portion sizes any more.
