Background:
Morbidly-obese patients with reflux who are undergoing sleeve gastrectomy (SG) may experience resolution, or persistent reflux. We studied factors associated with reflux resolution after SG.
Method:
We evaluated baseline weight, body mass index, and DeMeester score (DMS) in patients with reflux undergoing SG. Outcome measure was resolution of reflux post-operatively.
Results:
Study group included 70 patients; 33 (47.1%) patients reported resolution of reflux (RR group) after surgery; 37 (52.9%) patients didn't have resolution (NR group). Pre-operative weight, body mass index, percent excess BMI loss and presence of ≤2 cm hiatal hernia (HH) were similar between the two groups. Males and lower pre-operative DMS were associated with resolution of reflux (18.4 ± 13 vs. 29.1 ± 26, p = 0.03).
Conclusion:
Lower pre-SG DeMeester score tend to imply ability to resolve reflux in morbidly-obese patients thus, SG may still be offered, without repair of ≤2 cm HH if present. Unfortunately, it can't be used as the only factor.
