Preliminary Results of a Study Comparing Pre-sleeve Endoscopic Fundoplication to Gastric Bypass on Gastroesophageal Reflux Disease Outcomes.

Abstract

Gastroesophageal reflux disease (GERD) is a significant complication of sleeve gastrectomy (SG). Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is considered the primary treatmentfor bariatric surgery candidates with GERD. Post-operative options for GERD management are limited. This study compares the effect of transoral fundoplication (TF) prior to SG vs LRYGB in patients with GERD . Of 30 consecutive bariatric surgery patients with GERD between 3/22/2018 and 6/23/2020, 15 patients underwent TF prior to SG (TF/SG) and 15 patients underwent LRYGB. Subjective and objective criteria, including the GERD Health-Related Quality of Life (HRQL) and Reflux Symptom Index (RSI) survey, were used to assess symptoms. Surveys were collected pre-operatively, post-TF/pre-SG, 4-6 and 12-15months post bariatric procedure. Preoperative mean scores were as follows: HRQL 32.53, RSI 21.7, 93% proton pump inhibitor (PPI) usage, 6.5% satisfaction rate. Mean BMI: 45.99 (TF/SG), 42.27 (LRYGB). At 12-15months postoperatively: mean HRQL scores were 5.53 (TF/SG) and 6.67 (LRYGB). Both groups had a statistically significant improvement in HRQL-RSI postoperatively. PPI usage was 13% (TF/SG) and 34% (LRYGB). BMI decrease was 24% (TF/SG) and 31% (LRYGB). TF/SG is at least equivalent to LRYGB in resolution or reduction of reflux symptoms at 12-15months.
