About

This study aims to investigate the patterns of reflux symptoms after laparoscopic sleeve gastrectomy based on the presence or absence of preoperative gastroesophageal reflux symptoms.

Full description

Obesity is a well-known risk factor for gastroesophageal reflux disease (GERD), and laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric/metabolic surgery. However, patients often experience reflux symptoms after LSG, and those with severe reflux symptoms or severe erosive esophagitis have been excluded from candidates for LSG. This study aims to analyze the patterns of postoperative reflux symptoms based on the presence of preoperative reflux symptoms.

Prospectively established databases of patients assessed for reflux symptoms at a single institution will be retrospectively reviewed. A total of 64 patients who underwent LSG between April 2020 and March 2023 will be included in this study. The modified GERD-HRQL (GERD- health-related quality of life) questionnaire was used to evaluate gastroesophageal reflux symptoms before LSG and at 1, 3, 6, 9, and 12 months after surgery. Reflux symptoms will be categorized into heartburn and regurgitation, and the patterns of heartburn and regurgitation scores included in the modified GERD-HRQL questionnaire will be analyzed. The patients will be classified based on the presence or absence of preoperative reflux symptoms, and the patterns of symptom scores within each group will be analyzed. We will also measure the correlation between whether hiatal hernia repair was performed with laparoscopic sleeve gastrectomy and adiposity-related parameters, including preoperative and postoperative body mass index (BMI), preoperative and postoperative waist circumference (WC), the percentage of total weight loss (%TWL), and the percentage of WC reduction, and changes in postoperative symptom scores.

Enrollment: 64 patients

Sex: All

Ages: 20+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. patients with age greater than 19 years
2. patients who underwent laparoscopic sleeve gastrectomy from March 2019 to March 2023
3. patients with postoperative follow-up longer than one month after LSG
4. patients who answered preoperative and postoperative GERD questionnaire (Korean translated version of modified GERD-HRQL)

Exclusion criteria

1) patients with missing or incomplete postoperative GERD questionnaires

Trial design

64 participants in 2 patient groups

Preoperative symptom presence group

Description:

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.

Treatment:

Procedure: Laparoscopic sleeve gastrectomy

Preoperative symptom absence group

Description:

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.

Treatment:

Procedure: Laparoscopic sleeve gastrectomy
