Preoperative High-Resolution Manometry Criteria are Associated with Dysphagia After Nissen Fundoplication.

HRM criteria could not predict the development of postoperative dysphagia. However, in those with preoperative dysphagia and strong manometry criteria, dysphagia is more likely to resolve after Nissen fundoplication. Meanwhile, in those with preoperative dysphagia and weak manometry, dysphagia may persist and these patients may be better served with a partial fundoplication.
