The Effect of Laparoscopic Sleeve Gastrectomy on Gastroesophageal Reflux Disease

Flavia Carvalho Silveira et al. Obes Surg. 2021 Mar.

Abstract

Background: The laparoscopic sleeve gastrectomy (LSG) has become one of the most popular surgical weight loss options. Since its inception as a procedure intended to promote durable weight loss, the association between LSG and gastroesophageal reflux disease (GERD) has been a point of debate. First and foremost, it is known that GERD occurs more frequently in the obese population. With the sleeve gastrectomy growing to be the predominant primary bariatric operation in the United States, it is imperative that we understand the impact of LSG on GERD.

Objective: To examine the effects of LSG on GERD symptoms.

Methods: One hundred and ninety-one bariatric surgery candidates completed a Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) questionnaire before and after undergoing elective LSG (mean follow-up time of 20.4 ± 2.7 months). Values were stratified by the presence or absence of preoperative GERD, GERD medications, age, gender, crural repair, patient satisfaction with present condition, and percent total weight loss (%TWL).

Results: For the entire group, mean weight loss, %TWL, and reduction in BMI were 79 pounds, 28.1%, and 12.7 kg/m2 respectively. Within the overall cohort, there was no significant change in GERD symptoms from before to after surgery (mean GERD-HRQL scores were 6.1 before and after surgery, p = 0.981). However, in a subgroup analysis, patients without GERD preoperatively demonstrated a worsening in mean GERD-HRQL scores after surgery (from 2.4 to 4.5, p = 0.0020). The percentage of change in the usage of medications to treat GERD was not statistically significant (from 37 to 32%, p = 0.233). The percent of patients satisfied with their condition postoperatively was significantly increased in those with preoperative GERD, older age, crural repair intraoperatively, and in those with the highest %TWL.

Conclusion: These results suggest that while overall LSG does not significantly affect GERD symptoms, patients without GERD preoperatively may be at risk for developing new or worsening GERD symptoms after surgery. It is important to remark that this is a review of the patient's clinical symptoms of GERD, not related to any endoscopic, pathological, or manometry studies. Such studies are necessary to fully establish the effect of LSG on esophageal health.
