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.\n\nObjective:\n\nTo 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).', 'detailedDescription': 'Patients and methods:\n\nA total of 70 patients will be recruited and randomized to two groups with a 1:1 allocation ratio. Patients in the control group receive LSG alone and in the experimental group receive LSG with HHR. All subjects should provide basic clinical and demographic information, be evaluated for GER symptoms using GerdQ score, sign informed consent, and complete preoperative abdominal computed tomography (CT) scan, esophagogastroduodenoscopy (EGD), and HRIM. Outpatient follow-up would be arranged 1 weeks after discharge, then 1 month, 3 months, 6 months, and 12 months after surgery. Weight change and GER symptoms will be evaluated at every outpatient visit. Abdominal CT scan, EGD, and HRIM will be performed 12 months after surgery.\n\nExpected results:\n\nLess reflux esophagitis, less impedance reflux episodes, lower incidence of hiatal hernia, higher EGJ resting pressure, and longer LES length should be observed in morbidly obese patients receiving LSG with HHR at 12-month follow-up, using EGD and HRIM as evaluation tools. Furthermore, lower GerdQ score should be observed in these patients.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with:\n\n 1.
