NCT04884074

Brief Summary

The purpose of the study is to evaluate the superiority of anterior crural repair during sleeve gastrectomy over no repair in decreasing the incidence of gastroesophageal reflux disease.

    Defined by GerdQ score \> 7

    1 year

Study Arms (2)

The study group

EXPERIMENTAL

The procedure done to this group is Sleeve Gastrectomy with Anterior Crural Repair (ACR)

Procedure: Standard Sleeve Gastrectomy plus Anterior Crural Repair

The control group

OTHER

The procedure done to this group is the Standard Sleeve Gastrectomy (SSG)

Procedure: Standard sleeve gastrectomy (SSG, the control group)

Interventions

The procedure is performed in a similar fashion as standard sleeve gastrectomy. After gastric mobilization is completed as standard sleeve gastrectomy, the anterior phrenoesophageal ligament is divided and distal 3cm esophagus is mobilized. A Mid-Sleeve tube (40Fr) is inserted per-orally by the anesthetist and the hiatus opening is closed with 2/0 non-absorbable suture over the bougie anterior to the esophagus. The hiatus repair was sized by comfortably placement a dissection forceps adjacent to the esophagus without tension. Sleeve gastrectomy is then performed as the standard technique.

The study group

The procedure is performed in French position with a standard 5-port approach and a pneumoperitoneum not exceeding 15mmHg. The greater omentum is then completely detached from the greater curvature of stomach using either ultrasonic or bipolar shear device. All adhesion between posterior gastric wall and pancreatic capsule is freed and the cardia is completely free with left crura completely exposed. A Mid-Sleeve tube (40Fr) is inserted per-orally by the anesthetist with its balloon tip reaching the gastric antrum and insufflated with 50cc of air. Sleeve gastrectomy is then performed using laparoscopic linear staplers, starting from a point 5-6cm proximal to the pylorus up cardia at about 1cm lateral to the angle of His, along the Mid-sleeve tube which is lying against the lesser curve of stomach. The staple line is reinforced with absorbable sutures. Distal stomach is anchored at retroperitoneum with non-absorbable stitch.

Masking Details
The randomization is done by telephone call to the randomization centre where a dedicated research assistant without detailed knowledge of the recruited patient's background will open a sealed envelope containing a computer-generated random number which indicates the mode of intervention. Both the patients and clinical assessors (independent of the operating surgeons) are blind to the mode of intervention in the first one year of enrollment.
