Id: 3524447 variability in endoscopic assessment of nissen fundoplication wrap integrity and hiatus herniation: a multi-center study

Upper endoscopy (EGD) is frequently performed in patients with esophageal complaints following anti-reflux surgery. However, the evaluation of fundoplication wrap integrity in this setting may be challenging and associated with disagreement among providers. We therefore performed a multi-center study to evaluate the accuracy and confidence of assessing Nissen fundoplication integrity and hiatus herniation among endoscopists.
