Brief Summary

Background: Obesity and hiatal hernia are both risk factors of gastroesophageal reflux disease (GERD), and the incidence of hiatal hernia is much higher in morbidly obese patients. Many believe that higher intra-abdominal pressure with higher esophagogastric junction (EGJ) pressure gradient in morbidly obese patients is the main mechanism accounting for the occurrence of GERD. Hiatal hernia, on the other hand, is associated with structure abnormality of EGJ. Sleeve gastrectomy (SG) has been becoming a standalone bariatric surgery for decades, and it has been proved to effectively induce long-term weight loss in morbidly obese patients. Some studies found morbidly obese patients benefited from resolution of GERD after SG, however, other studies had the opposite findings. Some morbidly obese patients had aggravating GERD or de novo GERD after SG. The mechanism is still unclear now. It might result from removal of fundus and sling muscular fibers of EGJ, increased intra-gastric pressure (IIGP), and hiatal hernia after surgery. High resolution impedance manometry (HRIM) is used to access esophageal and EGJ function objectively. Impedance reflux was more frequently observed in patients having gastroesophageal reflux (GER) symptoms after SG. In addition, previous studies also found decreased EGJ resting pressure, decreased length of lower esophageal sphincter (LES), and presence of hiatal hernia were associated with more GERD after SG. Objective: To evaluate the long-term EGJ function and GERD in morbidly obese patients with hiatal hernia receiving laparoscopic sleeve gastrectomy (LSG) with or without hiatal hernia repair (HHR).

Study Arms (2)

LSG alone

ACTIVE COMPARATOR

Intervention: laparoscopic sleeve gastrectomy alone. LSG will be performed laparoscopically via a 5-port technique. The greater omentum is dissected by using the 5-mm laparoscopic LigaSure or Harmonic from 4 cm proximal to the pyloric ring to the angle of His. Sleeve calibration is done by a 36-French bougie inserted along the lesser curvature. Then the stomach is transected with sequential firings of linear green, gold, and blue 60 mm staplers starting about 4 cm proximal to the pylorus and ending approximately 2 cm distal to the left of the esophagus. The staple-line of the remnant gastric tube is oversewn with 3-0 V-Loc to prevent leakage and hemorrhage.

Procedure: Laparoscopic sleeve gastrectomy alone

LSG + HHR

EXPERIMENTAL

Intervention: concomitant laparoscopic sleeve gastrectomy + hiatal hernia repair. The surgical detail of LSG is the same as described in "LSG alone" arm, and the surgical detail of HHR is described as below. The hiatus is approached from the right side of the EGJ, through the lesser omentum. The hiatal defect is repaired by 1-0 Surgilon interruptedly, and then a commercialized "U-shaped" Biodesign Hiatal Hernia Graft is placed to the EGJ to cover the posterior side but spare the anterior side of the hiatus. Care must be taken to avoid direct contact of mesh to the esophagus to avoid any unnecessary complication. After the mesh is appropriately placed and oriented, 2 ml of TISSEEL solution for sealant is applied all over the mesh for fixation.

Procedure: Laparoscopic sleeve gastrectomy + Hiatal hernia repair

Interventions

To evaluate the role of concomitant hiatal hernia repair in laparoscopic sleeve gastrectomy for morbidly obese patients.

LSG + HHR

Current mainstay and standard surgical treatment for morbidly obese patients.

LSG alone
