Outcome Measures

Primary Outcomes (1)

  • Symptom scores from the modified GERD-HRQL

    The modified GERD-HRQL consists of 15 questions with a 6-point Likert scale ranging from 0 to 5. Among these, six questions are related to heartburn, while another six focus on regurgitation. Symptom scores including heartburn and regurgitation scores were defined as the sum of the six questions related to each symptom.

    before laparoscopic sleeve gastrectomy and at 1, 3, 6, 9, 12 months after surgery

Secondary Outcomes (2)

  • Hiatal hernia repair with laparoscopic sleeve gastrectomy (performed or not)

    during laparoscopic sleeve gastrectomy

  • Adiposity-related parameters

    before laparoscopic sleeve gastrectomy and at 1, 3, 6, 9, 12 months after surgery (WC: before laparoscopic sleeve gastrectomy and at 3, 6, 9, 12 months after surgery)

Study Arms (2)

Preoperative symptom presence group

Patients whose preoperative symptom score from the modified GERD-HRQL questionnaire is not zero. For analyses of each symptom (heartburn and regurgitation), patients will be grouped based on the presence of the respective symptom: the heartburn symptom presence group for heartburn analysis and the regurgitation symptom presence group for regurgitation analysis.

Procedure: Laparoscopic sleeve gastrectomy

Preoperative symptom absence group

Patients whose preoperative symptom score is zero, as assessed by the modified GERD-HRQL questionnaire. For each symptom analysis (heartburn and regurgitation), patients will be grouped based on the presence of the respective symptom: the heartburn symptom absence group for heartburn analysis and the regurgitation symptom absence group for regurgitation analysis.

Procedure: Laparoscopic sleeve gastrectomy

Interventions

Laparoscopic sleeve gastrectomy (LSG) is most commonly performed bariatric/metabolic surgery. LSG is performed in patients with obesity and/or obesity-related comorbidities. During LSG, the stomach was resected from 5 cm proximal to the pylorus to the angle of His, guided by a 36-French bougie. In patients with hiatal hernia, concomitant HHR was also performed with LSG using non-absorbable sutures. Routine oral potassium-competitive acid blocker (PCAB) was prescribed for 3 months after surgery and the discontinuation of PCAB was determined based on GERD symptoms at the 3-month visit.
