Abstract
Background
Gastroesophageal reflux disease (GERD) is a possible side effect of sleeve gastrectomy (SG). However, procedure selection for patients with GERD and risk factors for morbidity after bypass surgeries is complex. For patients with a preoperative GERD diagnosis, literature related to worsening postoperative symptoms is discordant.
Objective
This study evaluated the effects of SG on patients with pre-operative GERD confirmed through pH testing.
Setting
University Hospital, United States.
Methods
This was a single-center case-series. SG patients with preoperative pH testing were compared based on DeMeester scoring. Preoperative demographics, endoscopy results, need for conversion surgery, and changes in gastrointestinal quality of life (GIQLI) scores were compared. Two-sample independent t-tests assuming unequal variances were used for statistical analysis.
Results
Twenty SG patients had preoperative pH testing. Nine patients were GERD positive; median DeMeester score 26.7 (22.1–31.15). Eleven patients were GERD negative, with a median DeMeester score of 9.0 (4.5–13.1). The two groups had similar median BMI, preoperative endoscopic findings and use of GERD medications. Concurrent hiatal hernia repair was performed in 22% of GERD positive vs. 36% of GERD negative patients, (p = 0.512). Two patients in the GERD positive cohort required conversion to gastric bypass (22%), while none in the GERD negative cohort did. No significant postoperative differences were noted in GIQLI, heartburn, or regurgitation symptoms.
Conclusion
Objective pH testing may allow the differentiation of patients who would be higher risk for need for conversion to gastric bypass. For patients with mild symptoms, but negative pH testing, SG may represent a durable option.
