Sleeve And Weight Regain

Posted On : July 22, 2019 Sleeve gastrectomy has become the most frequently performed operation in the US. Sleeve as a part of the Duodenal Switch or as a stand alone operation has been offered in our practice for nearly 20 years. As a precondition to this, patients’ choosing to have the sleeve, especially with high BMI (>45) and those with metabolic conditions (diabetes, high cholesterol or triglycerides, PCOS, and others) we have always recommended Duodenal Switch as the procedure of choice instead of the Sleeve Gastrectomy due to improved and lasting co-morbid resolution  and weight loss maintenance with Duodenal Switch. It has been know for years that a sizable number of patients having the sleeve will experience weight regain requiring conversion to the duodenal switch or the RNY Gastric Bypass. Majority of the patients having gained weight after sleeve, or experiencing the return of co-morbidities after a transient resolution during the their weight loss phase, should only be revised to the Duodenal switch operation in my opinion. The alternative procedures of SIPS and SADI or similar single anastomosis operation with confusing nomenclature should be avoided, since as of the publication of this blog they are still considered investigational by the American Society for Metabolic and Bariatric Surgery (ASMBS) with no long term data.  The only plausible reason for revision of the Sleeve to the gastric bypass (RNY) would be those patients who are experiencing reflux. Felsernreich et.al. demonstrated that 10 years after sleeve gastrectomy  33% were requiring revisions of their sleeve due to weight regain or reflux. 66% needed revision for weight loss and only 34% for reflux. Those patients who have revision to gastric bypass (in their practice all being revised with two exception) had resolution of their reflux however had no sustained weight loss after the revisions. This supports our position that we have had for years that the those patient who had the sleeve and are experiencing weight regain, recurrence of comorbidities inadequate weight loss ahould all be revised to the duodenal switch operation.
