Abstract
Background
The ICARUS guidelines are a systematic review and Delphi process that provide recommendations in the treatment and management of patients with gastroesophageal reflux disease (GERD). Many of the recommendations were supported by randomized trials; some were not. This study assesses guidelines with limited evidence and weak endorsement.
Methods
Four ICARUS guidelines were chosen: the role of fundoplication for patients with BMI > 35, regurgitation, chest pain, and extra-esophageal symptoms. A multicenter database of patients undergoing fundoplication surgery for GERD between 2015 and 2020 was used. Outcomes assessed were anatomic failure and symptom recurrence. Multivariable regression was performed.
Results
Five institutions performed a fundoplication on 461 patients for GERD with a median of follow-up of 14.7 months (IQR 14.2). On multivariate analysis, patients with the chosen pre-operative comorbidities achieved comparable post-operative benefits. Patients with a BMI > 35 were not more likely to experience anatomic failure. Patients with pre-operative regurgitation had similar symptom recurrence rates to those without. Patients with non-cardiac chest pain had comparable rates of symptom recurrence to those without. Reporting a pre-operative chronic cough attributable to reflux was not associated with higher rates of post-operative symptom recurrence.
Discussion
Among the ICARUS guidelines and recommendations, a small proportion was lacking evidence at low risk for bias and endorsement. The results of this multicenter study evaluated outcomes of patients with various pre-operative conditions: BMI > 35, chest pain attributable to reflux, extra-esophageal symptoms attributable to reflux, and regurgitation. Our findings endorse patients with these characteristics as candidates for anti-reflux surgery.
