Bolus exposure as a novel predictor of postoperative symptom resolution after laparoscopic nissen fundoplication: A two-institutional retrospective cohort study

Even in the absence of definite evidence of pathological acid reflux, antireflux surgery (ARS) can still effectively improve gastroesophageal reflux symptoms. Nonetheless, predicting postoperative reflux symptom improvement has been primarily dependent on acid-based parameters. No objective index reflecting both acid and non-acid reflux was identified to select ARS candidates.
