This study compared differences in weight loss, comorbidity resolution and complications and reoperations between a recently established sleeve gastrectomy (SG) and prior laparoscopic Rox-en-Y gastric bypass (RYGB).
This retrospective study with prospectively collected registry data presents results from establishment of SG as standard procedure for morbid obesity. Our first 368 patients operated with a SG were compared to 647 patients previously operated with a (RYGB. Perioperative data and results up to 2 years postoperatively regarding weight control, metabolic control as well as complications/reoperations necessary were registered.
In summary, a RYGB was associated with a longer operation time and higher rates of late complications and reoperations. Diabetes resolution was similar in both groups but patients with a RYGB had greater weight loss and significant improvement in hypertension and dyslipidemias.
