Approximately 2 years after a sleeve gastrectomy or gastric sleeve, the volume of the stomach can expand. As the stomach expands, some patients begin to eat more. These patients may benefit from a bariatric revision surgery.
There are various surgical options that a patient may have at their disposal when experiencing weight regains after a sleeve gastrectomy. Options include conversion to a bypass, conversion to a duodenal switch or re-sleeving. In addition, these same surgical options may even correct issues or side effects (such as acid reflux) that are no longer responsive to medical therapy. With the expertise of one of Texas’s top bariatric surgeons, Dr. Bonnor, you can ensure that you will get the best possible results to aid you in your weight loss goals.

Am I a Candidate for Gastric Sleeve Revision Surgery?
Before proceeding with a revision operation, it is imperative to perform an adequate evaluation of the existing anatomy. To determine this, an upper endoscopy and an upper gastrointestinal study (where the patient drinks a contrast liquid) is typically required. Taking into consideration the anatomic findings as well as your current symptoms will almost invariably determine what type of revision operation is best for you. For example, a conversion of a sleeve gastrectomy to a gastric bypass is particularly effective for those who also have an element of reflux as the bypass would treat both the reflux and help with weight loss.
Other Surgery Revision Options
A sleeve gastrectomy can also be revised to a duodenal switch procedure. The duodenal switch is a combination of a gastric sleeve and an intestinal bypass. Years ago the duodenal switch was routinely performed for patients with a high BMI. The sleeve gastrectomy was done first, and then after initial weight loss, the surgeon completed the intestinal bypass.
Many patients had such good results with a sleeve gastrectomy alone and therefore did not need a second step.
Now, in a patient with a previous sleeve gastrectomy that requires more weight loss, surgeons can perform a completion or so-called second stage duodenal switch. Overall, the duodenal switch has demonstrated the best weight loss results. Therefore, a patient who does not experience adequate weight loss results with the primary sleeve gastrectomy may be a good candidate for revising to a duodenal switch.
Consideration Post Gastric Sleeve Revision Surgery
Because of the number of intestines bypassed, there is a greater risk of vitamin deficiency with the duodenal switch compared to a primary sleeve gastrectomy. Like the gastric bypass operation, patients need to take vitamin supplementation regularly. In a few cases, we may also consider re-sleeving—trimming a portion for the stomach that has re-expanded to create a smaller tube or sleeve. Here at Texas Endosurgery, we are Houston’s leading provider of bariatric surgery with an emphasis on patient safety and satisfaction.
