Background: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The investigators' preliminary study suggests that the incidence of postoperative GERD and EE appears to be correlated with the preoperative presence of a lax gastroesophageal flap valve and hiatal hernia. Hypothesis/ Aim: To investigate the impact of a concomitant hiatal hernia repair with LSG on the incidence of postoperative EE. Significance: For patients with pre-existing EE, most surgeons will recommend a laparoscopic Roux-en-Y gastric bypass (LRYGB) as their primary bariatric procedure. However, compared to LSG, LRYGB is a technically more demanding procedure with increased morbidity and long term nutritional deficiencies. For asymptomatic patients at risk of postoperative EE due to presence of a hiatal hernia, there is still no consensus on the most appropriate bariatric surgical option. A LSG with a concomitant hiatal hernia repair, if shown to reduce EE postoperatively, may help to expand the pool of patients suitable for LSG in the future. Methods: A two center, double-blinded, randomized controlled trial of all patients, undergoing LSG with a preoperative diagnosis of a Hill's grade III gastroesophageal junction, will be randomized to having a concomitant hiatal hernia repair (experimental arm) versus just LSG alone (control arm). Primary outcome measures include 1-year postoperative EE on endoscopy. Secondary outcome measures include postoperative morbidity, blood loss, quality of life and GERD symptoms at 1-year postoperatively.

Primary | Degree of Post-operative erosive esophagitis | Grading of erosive esophagitis on endoscopy, noted as absent, or grade A, B, C or D (based on the Los Angeles classification) | 1-year | |
Secondary | General Quality of Life Scores | 36-item Short Form Survey. It is a commonly employed questionnaire to assess overall quality of life. It comprises 36 short questions, which directly translates into a 0-100 scoring system. The higher the scores, the better the quality of life. | 3-month, 6-month, 9-month, 1-year | |
Secondary | Gastroesophageal reflux disease symptoms | Gastrointestinal Symptom Rating Scale. It is a questionnaire assessing 5 different symptom clusters of gastrointestinal symptoms, namely Reflux, Abdominal pain, Indigestion, Diarrhea and Constipation. Each domain has a 7-point graded scale, where 1 represents no symptoms and 7 represents very troublesome symptoms. Hence, the higher the scores in a particular domain, the more troublesome the symptoms. In assessing the endpoint of gastroesophageal reflux disease symptoms, the domain of reflux in the GSRS questionnaire will be evaluated. | 3-month, 6-month, 9-month, 1-year | |
Secondary | Dysphagia symptoms | Gastrointestinal Symptom Rating Scale. It is a questionnaire assessing 5 different symptom clusters of gastrointestinal symptoms, namely Reflux, Abdominal pain, Indigestion, Diarrhea and Constipation. Each domain has a 7-point graded scale, where 1 represents no symptoms and 7 represents very troublesome symptoms. Hence, the higher the scores in a particular domain, the more troublesome the symptoms. In assessing the endpoint of dysphagia symptoms as the secondary outcome, the domain of indigestion in the GSRS questionnaire will be evaluated. | 3-month, 6-month, 9-month, 1-year | |
Secondary | Gastrointestinal reflux disease specific quality of life scores | Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD). The QOLRAD (reflux version) is a 25-item questionnaire specifically focusing on gastroesophageal reflux symptoms. It can be scored based on frequencies, from none of the time to all of the time, for each question. The higher the frequency, the more prevalent the symptoms. | 3-month, 6-month, 9-month, 1-year |
