Comparison of the Sleeve Gastrectomy Technique With a Nissen Fundoplication Added to the Conventional Sleeve Gastrectomy Technique in Morbidly Obese Patients

University Hospital, Montpellier2 enrolled

Overview

The purpose of this study is to evaluate the impact of the procedure (sleeve gastrectomy technique with a Nissen fundoplication (N-Sleeve) vs conventional sleeve gastrectomy technique

Bariatric surgery is recognized as the only effective therapeutic weapon for morbidly obese patients. Gastro-Oesophageal Reflux Disease is very common (30-45% of cases) with serious consequences on the oesophageal mucosa. It could be an exacerbation of preoperative GERD symptoms or a "de novo" postoperative GERD. Medical treatment is usually effective but reoperation may be required to treat refractory GERD.GERD can lead to serious consequences on the oesophageal mucosa (esophagitis, Barrett's oesophagus, cancer). The conventional surgical treatment of GERD is fundoplication, which can be partial or total. The gastric fundus is wrapped around the oesophagus to strengthen the tone of the oesophageal sphincter. We hypothesize that the creation of a total anti-reflux fundoplication before performing LSG (Nissen + Sleeve = N-sleeve) could significantly reduce the postoperative GERD complication as compared with the standard LSG. To evaluate the impact of the procedure N-Sleeve vs conventional sleeve gastrectomy technique on the rate of patient with GERD at 1, 6 and 12 months postoperatively. To evaluate the impact of the procedure (sleeve gastrectomy technique with a Nissen fundoplication (N-Sleeve) vs conventional sleeve gastrectomy technique during all the follow-up on the gastric fistula on the staple line, on the postoperative morbidity and mortality , on the evolution of weight loss, the excess weight loss, the BMI and the excess BMI loss during the follow-up. Evaluate the impact of these procedures on the quality of life of patients at baseline and 1, 6 and 12 months postoperatively. Evaluate the safety during all the follow-up. •Methods: Monocentric, randomized, single-blind controlled trial, with 2 parallel arms. 144 patients. The target population is all adult patients with severe or morbid obesity, who underwent multidisciplinary care and having the criteria of 2009 HAS recommendations for bariatric surgery. Presence of gastro-oesophageal reflux will be assessed by a composite criteria: consumption of Proton Pump Inhibitor and gastroscopy at baseline and 12-month. The N-SLEEVE technique consists of creating a gastric total fundoplication before to perform the removal of 2/3 of the stomach. This study may really lead to a change in terms of choice of first intention bariatric procedures.

Outcomes

Primary Outcomes

Presence of gastroesophageal reflux disease

Gastroscopy is a standard endoscopic examination that examines the lining of the oesophagus and stomach. It can detect Helicobacter pylori and highlight the presence of: * Gastro-Oesophageal Reflux Disease * Gastritis * Esophagitis * Barrett's oesophagus * Hiatal hernia * Gastric tumor * Bile reflux * Incompetent cardia

Time frame: 12 months

Consumption of Proton Pump Inhibitor

The consumption of PPI, revealing the presence of GERD symptoms, will be recorded at each visit thanks a diary card.

Time frame: 12 months

Secondary Outcomes

type of fistula Month 1

The diagnosis is confirmed by conducting a CT with contrast medium opacification. 4 stages are defined I, II, III and IV. TDM will be realized only in case of suspicion of fistulas (fever, pain in the left shoulder, vomiting). The type, the severity and the time between the date of occurrence of fistula and the date of the surgery will be recorded at each visit.

Time frame: Month 1

severity of fistula Month 1

The severity of fistula is classified depending on the classification of Montpellier 2013 (Nedelcu)

Time frame: Month 1

type of fistula Month 6

Time frame: Month 6

severity of fistula Month 6
