The Effect of Laparoscopic Sleeve Gastrectomy on Symptoms of Gastroesophageal Reflux Disease.

Abstract

Background Laparoscopic sleeve gastrectomy (LSG) is a common bariatric procedure for weight loss. LSG is becoming prevalent worldwide because it is a relatively simple procedure with high efficacy. Reduced intraabdominal pressure may improve gastroesophageal reflux disease (GERD) symptoms and reduce the GERD medication needed following LSG. However, the main long-term drawback of LSG is the development of de novo GERD. Therefore, we conducted this study to determine the relationship between GERD symptoms and LSG. Methods We conducted a retrospective chart review involving 390 patients who underwent LSG. Study participants were evaluated for GERD symptoms six months before and three, six, and nine months after the procedure, and proton-pump inhibitors (PPIs) were used to control the symptoms. Participants were distributed into two groups: one group for patients with GERD symptoms (36.1%) and one group for asymptomatic patients (62.8%). We collected demographic data and assessed PPI use in both groups after three, six, and nine months postoperatively. Data were collected using Microsoft Excel (Microsoft Corporation, Redmond, WA) and analyzed using IBM SPSS Statistics for Windows, Version 20.0(Armonk, NY: IBM Corp.). We compared data using the student's t-test for independent groups. The quantitative data were summarized using mean and standard deviation (SD), and p < 0.05 was considered statistically significant. Results Of the 390 participants who underwent LSG, 83.8% were women (n=327)and 16.2% were men (n=63), with a median age of 42 ± 11.9 years. PPI use was statistically significantly greater after LSG (34.1%) than before LSG (24.6%, p=0.019). The difference in PPI use between symptomatic and asymptomatic groups was not statistically significant three months after LSG. Conclusions Our study focuses on using PPI after LSG due to GERD symptoms. We found GERD symptoms improved three months following LSG, but de novo GERD symptoms occurred nine months after the surgery. Health providers need to discuss with their patients the potential outcomes of the surgery and manage patient expectations. Physicians should work with their patients to assess whether the benefits of bariatric surgery in controlling overweight-associated conditions, such as blood pressure, diabetes,sleep apnea, and weight loss, outweigh the risk of GERD symptoms and PPI use.
