This is the first component of a BPD-DS where the stomach is reduced in size by removing the lateral 2/3rds leaving the stomach in the shape of a tube.
Sometimes, it is offered to patients as part of a two-stage Bypass operation, particularly if they are super obese ( BMI>60), because it allows good weight loss until the patient gets down to a safe weight. The more radical bypass can then be offered laparoscopically when they are at a safer weight.
The residual stomach capacity is about 200mls so a generous entree
should be possible.
Sleeve Gastrectomy Disadvantages
- Stomach tube may stretch up over time leading to late weight regain. The extent of this is currently unknown
- The amount of weight reduction is in the region of 40-60% of excess wt lost over the first 1-2 years
- It is a good option for people living in remote areas because it is a “set and forget” operation which requires little post op follow up or nutritional supplements
- There is no malabsorbtion to nutrients
- If weight is regained the second stage of the BPD the intestinal bypass can be added
