Is barium esophagram enough? Comparison of esophageal motility found on barium esophagram to high resolution manometry.

The aim of the study is to determine if barium esophagram (BE) alone is sufficient to diagnose esophageal dysmotility when compared to the gold standard, high-resolution manometry (HRM). This is a retrospective review of patients that underwent laparoscopic fundoplication by two surgeons at a single institution from 10/1/2015-6/29/2019. Patients with large paraesophageal hernias and patients without both BE and HRM were excluded. Forty-six patients met the inclusion criteria. BE was found to be concordant with HRM for esophageal motility in only 21 patients (46%). Setting HRM as the gold standard, BE had a sensitivity of 14% (95% CI: 5%-35%), specificity of 72% (95% CI: 52%-86%), PPV of 30% (95% CI: 11%-60%), and NPV of 50% (95% CI: 35%-66%). The accuracy was 46%, while a McNemar test showed p = 0.028. Traditional BE should not be used in place of HRM for assessing pre-operative motility in patients undergoing anti-reflux surgery.
