Overview
Obesity is a major public health problem worldwide. Bariatric surgery has proved to be the most effective treatment of morbid obesity in terms of weight reduction and remission of co-morbid conditions during long-term follow-up. Sleeve Gastrectomy (SG) has become the most performed intervention either worldwide or in France, where SG represents more than 60% of bariatric interventions and 114,817 patients operated between 2013 and 2016.
Maximum Excess weight loss (%EWL) after SG is obtained at one-year post surgery. Then it has been largely reported in the literature that patients could present mild, moderate or important (notably in the super obese patients) weight regain associated with comorbidity relapse motivating redo surgery. Like in revisional surgery, operating super-obese patient (BMI ≥50 kg/m2) is a challenge. It has been shown that achieving significant weight loss was more difficult in patients with a BMI ≥ 50 compared to lower BMIs.
Description
In these 2 populations of patients, more malabsorptive procedures like long limb One Anastomosis Gastric Bypass or Bilio-Pancreatic Diversion with Duodenal Switch could be more efficient but induce technical difficulties (high complication rate) and can be responsible for malnutrition (vitamin deficiencies, hypoalbuminemia…). That's why, in case of revisional surgery or for high BMI patients,laparoscopic Roux-en-Y gastric bypass (RYGBP) is still considered as the gold standard and is the most performed intervention. To obtain better weight loss safely,Santoro et al. promoted the sleeve gastrectomy with transit bipartition (SG+TB), a new intervention coupling a SG without interrupting pathway through the duodenum and preserving the pylorus and a long biliary limb RYGBP.
Hypothesis: Because there is no duodenal and jejunal exclusion, malnutrition is expected to be less frequent after SG+TB compared to BPD/DS. Its anastomosis on the antrum makes SG+TB easier to perform in super-obese patient than standard RYGB but more efficient in term of weight loss. Compared to BPD/DS or SADI which involves dissection of the duodenum and the confection of a duodenojejunostomy, SG+TB is also expected to be easier then safer.
