Lower pre-operative DeMeester scores in morbidly-obese patients predict reflux resolution after sleeve gastrectomy (SG). This suggests SG can be effective for managing reflux, but other factors also play a role.
Area of Science:
- Gastroenterology
- Bariatric Surgery
- Obesity Medicine
Background:
- Gastroesophageal reflux disease (GERD) is a common comorbidity in morbidly obese patients.
- Sleeve gastrectomy (SG) is a bariatric procedure that can impact GERD.
- Reflux resolution varies among patients post-SG.
Purpose of the Study:
- To identify factors associated with the resolution of reflux after sleeve gastrectomy in morbidly obese patients.
- To evaluate the predictive value of pre-operative parameters on post-operative reflux status.
Main Methods:
- A cohort of 70 morbidly obese patients undergoing SG for reflux were evaluated.
- Baseline weight, body mass index (BMI), and DeMeester score (DMS) were assessed pre-operatively.
- Resolution of reflux post-operatively was the primary outcome measure.
Main Results:
- 47.1% of patients experienced reflux resolution (RR group), while 52.9% did not (NR group).
- Pre-operative weight, BMI, percent excess BMI loss, and presence of a small hiatal hernia (≤2 cm) were similar between groups.
- Male gender and lower pre-operative DeMeester scores were significantly associated with reflux resolution (p=0.03).
Conclusions:
- A lower pre-operative DeMeester score may indicate a higher likelihood of reflux resolution following sleeve gastrectomy.
- Sleeve gastrectomy may be a viable option for morbidly obese patients with reflux, even with a small hiatal hernia.
- The DeMeester score alone is insufficient to predict reflux resolution; other factors should be considered.
