Gastric Sleeve Surgery (Sleeve Gastrectomy) in Louisiana and Mississippi
The Gastric Sleeve is a restrictive procedure, meaning patients lose weight by limiting the amount of food they take in. There is no re-routing of the intestines and no change in the ability to absorb calories and nutrients such as iron, vitamin B-12, and calcium. Patients report a drastic decrease in hunger and an early feeling of “fullness” when they eat. The mechanism for weight loss is a decrease in calorie intake.
The Gastric Sleeve is performed laparoscopically, using special instruments that allow the surgeon to operate through 6-8 very small abdominal incisions. In this procedure a large portion of the stomach is removed, leaving a small tube shaped pouch. The capacity of the new stomach pouch is 3 to 4 ounces – larger than the stomach pouch created during Roux-en-Y gastric bypass and about the size of a banana.
Gastric Sleeve Surgery Results
Current evidence shows that the excess body weight loss at 12 months is 45% to 64%, with significant resolution of obesity related illnesses. Long term data (5 years or more) is not yet available, and there is still much research to be done.
Co-morbid condition resolution 12 to 24 months after sleeve gastrectomy has been reported in 345 patients. Sleeve gastrectomy patients experienced resolution rates for type 2 diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea that were similar to resolution rates for other restrictive procedures such as adjustable gastric banding.*

Potential Gastric Sleeve Patient Concerns
- The operative complication rates are comparable to that of laparoscopic gastric bypass and include gastric leak, bleeding, infection, and blood clots that can lead to pulmonary embolism.
- Long term complications that may require reoperation are less frequent than those for RYGB and adjustable gastric band
- Risks of nutritional deficiency are very low.
- Because there is no implant, as with the adjustable gastric band, there is no risk of mechanical failure, and the need for frequent follow-up adjustment visits is eliminated.
