Bolus exposure predicts postoperative symptom resolution better.

In a retrospective study involving 72 patients, bolus exposure emerged as a superior predictor for postoperative symptom resolution in gastroesophageal reflux disease (GERD) after laparoscopic Nissen fundoplication. It outperformed traditional parameters like acid exposure time and DeMeester score for predicting symptom relief, notably for epigastric pain and regurgitation. Notably, in patients without pathological reflux, bolus exposure retained significant diagnostic accuracy across various symptoms, suggesting its potential role in identifying candidates for antireflux surgery.
