Frequently asked questions
How long does a gastric sleeve revision procedure take?
The procedure itself takes approximately 30 to 45 minutes. However, you should plan on spending about half a day with us including preparation and recovery.
What is recovery like after a gastric sleeve revision procedure?
Patients go home on the same day. Most take a few days off to recover at home before returning to work. After the procedure, patients follow a full liquid meal plan, which includes protein shakes and similar products, then transition to a soft diet, which includes easy-to-eat foods such as oatmeal and bananas, and then return to regular eating.
How common are gastric sleeve revisions?
About 5-12% of people who had a sleeve gastrectomy underwent a revision, and 87% of those revisions were due to ongoing obesity.4 Those with a previous gastric band were more likely to need a revision. Most people opted for gastric bypass or resleeve, but since the introduction of the sleeve-in-sleeve procedure in 2018, an increasing number are choosing endoscopic revisions for safety.
How does an endoscopic gastric sleeve revision compare to a revisional surgery?
Endoscopic revision is safer, done through the mouth with a 1% complication rate, and offers quick recovery. Surgical revisions, such as recreating a smaller sleeve or converting sleeve gastrectomy to a gastric bypass or duodenal switch, are riskier with an average complication rate of 29%.3
What are the risks of the gastric sleeve revision procedure?
Discomfort, nausea, chest pressure, or spasms may occur. The major complication rate, including infection or bleeding, is less than 1%.
Is gastric sleeve revision covered by insurance?
Unfortunately, insurance does not cover endoscopic sleeve revision procedures yet. However, we offer several financing options. Learn more about our pricing and financing options.
