Summary

The study aims to clarify if GERD, defined by results of 24 hours potential of hydrogen (pH) monitoring and abnormal DeMeester Score (DMS), in obese patients could worsen after Sleeve Gastrectomy (SG) more than after RYGBP. To demonstrate this hypothesis, the investigators will study the obese population suspected for GERD with 24 hours monitoring and High-Resolution Esophageal Manometry (HRM). DMS is calculated pre-operatively and, once GERD is confirmed, the patients are enrolled for randomization to SG or RYGBP. The suspicion of GERD is investigated with the GERDQ score and EGDS, that all obese patients have pre-operatory.

Conditions

  • Gastroesophageal Reflux Disease
  • Obesity

Interventions

PROCEDURE

Roux-en-Y-Gastric bypass, Sleeve gastrectomy

RYGBP consists in creating a small gastric pouch along the little curvature of the stomach, followed by the section of the small bowel. The restoration of the gastro-intestinal tract is achieved by performing a gastro-jejunal and a jejuno-jejunal anastomosis, giving this procedure the characteristic aspect of a Y. Also, for RYGBP the laparoscopic approach requires the placement of 5 trocars in the upper part of the abdomen.

PROCEDURE

SG

SG consists in removing the fundus and the body of the stomach, along the greater curvature. To perform it with a laparoscopic approach, we create the pneumoperitoneum with Veress needle and place 5 trocars in the upper part of the abdomen. The first step is the dissection of the greater curvature of the stomach, that starts at 6 centimetres from pylorus and it's conducted up to the angle of His, freeing the fundus and exposing the left pillar. A 38 Fr bougie is placed inside the stomach to calibrate its section. After it is carried out, the specimen is removed from the greater trocar site.
