Biliopancreatic diversion[ edit ] This operation is termed biliopancreatic diversion BPD or the Scopinaro procedure. The original form of this procedure is now rarely performed because of problems with.
Part of the stomach is resected, creating a smaller stomach however the patient can eat a free diet as there is no restrictive component. The distal part of the small intestine is then connected to the pouch, bypassing the duodenum and jejunum.
The malabsorptive effect of BPD is so potent that, as in most restrictive procedures, those who undergo the procedure must take vitamin and dietary minerals above and beyond that of the normal population.
Without these supplements, there is risk of serious deficiency diseases such as anemia and osteoporosis. Others prefer to prescribe medications to reduce the risk of post-operative gallstones. Far fewer surgeons perform BPD compared to other weight loss surgeries, in part because of the need for long-term nutritional follow-up and monitoring of BPD patients.
Jejunoileal bypass This procedure is no longer performed. Endoluminal sleeve[ edit ] A study on humans was done in Chile using the same technique  however the results were not conclusive and the device had issues with migration and slipping.
A study recently done in the Netherlands found a decrease of 5. Vertical banded gastroplasty[ edit ] In the vertical banded gastroplastyalso called the Mason procedure or stomach stapling, a part of the stomach is permanently stapled to create a smaller pre-stomach pouch, which serves as the new stomach.
Adjustable gastric band The restriction of the stomach also can be created using a silicone band, which can be adjusted by addition or removal of saline through a port placed just under the skin.
This operation can be performed laparoscopically, and is commonly referred to as a "lap band". Weight loss is predominantly due to the restriction of nutrient intake that is created by the small gastric pouch and the narrow outlet.
Sleeve gastrectomy Sleeve Gastrectomy. The open edges are then attached together typically with surgical staplessutures, or both to leave the stomach shaped more like a tube, or a sleeve, with a banana shape. The procedure permanently reduces the size of the stomach. The procedure is performed laparoscopically and is not reversible.
It has been found to be comparable in effectiveness to Roux-en-Y gastric bypass. Intragastric balloon Intragastric balloon involves placing a deflated balloon into the stomach, and then filling it to decrease the amount of gastric space. The balloon can be left in the stomach for a maximum of 6 months and results in an average weight loss of 5—9 BMI over half a year.
Quoted costs for the intragastric balloon are surgeon-specific and vary by region. Average quoted costs by region are as follows provided in United States Dollars for comparison: Gastric plication significantly reduces the volume of the patient's stomach, so smaller amounts of food provide a feeling of satiety.
Mean patient age was 34, with a mean BMI of Follow-up visits for the assessment of safety and weight loss were scheduled at regular intervals in the postoperative period.
No major complications were reported among the 66 patients.
Weight loss outcomes are comparable to gastric bypass. The study describes gastric sleeve plication also referred to as gastric imbrication or laparoscopic greater curvature plication as a restrictive technique that eliminates the complications associated with adjustable gastric banding and vertical sleeve gastrectomy —it does this by creating restriction without the use of implants and without gastric resection cutting and staples.
Mixed procedures apply block and restrict at the same time. Gastric bypass surgery A common form of gastric bypass surgery is the Roux-en-Y gastric bypass, designed to reduce the amount of food a person is able to eat by cutting away a part of the stomach.
Gastric bypass is a permanent procedure that helps patients by changing how the stomach and small intestine handle the food that is eaten to achieve and maintain weight loss goals. A patient will feel full with less food. The gastric bypass had been the most commonly performed operation for weight loss in the United States, and approximatelygastric bypass procedures were performed in There are certain patients who cannot tolerate the malabsorption and dumping syndrome associated with gastric bypass.
In such patients, although earlier considered to be an irreversible procedure, there are instances where gastric bypass procedure can be partially reversed. Diagram of a sleeve gastrectomy with duodenal switch. Sleeve gastrectomy with duodenal switch[ edit ] A variation of the biliopancreatic diversion includes a duodenal switch.
The part of the stomach along its greater curve is resected. The stomach is "tubulized" with a residual volume of about ml.
This volume reduction provides the food intake restriction component of this operation.
This type of gastric resection is anatomically and functionally irreversible. The stomach is then disconnected from the duodenum and connected to the distal part of the small intestine.
Electrical stimulation is thought to modify the activity of the enteric nervous system of the stomach, which is interpreted by the brain to give a sense of satiety, or fullness.Remember this statement.
