Prosthetic reinforcement of posterior cruroplasty during laparoscopic hiatal herniorrhaphy.

Symptomatic gastroesophageal reflux after Nissen fundoplication may occur if the wrap herniates into the thorax. In an attempt to prevent recurrent hiatal hernia we employed polytetrafluoroethylene (PTFE) mesh reinforcement of posterior cruroplasty during laparoscopic Nissen fundoplication and hiatal herniorrhaphy. Three patients with symptomatic gastroesophageal reflux and a large (>==8 cm) hiatal defect underwent laparoscopic posterior cruroplasty and Nissen fundoplication. The cruroplasty was reinforced with a PTFE onlay. No perioperative complications occurred, and in follow-up (<==11 months) the patients are doing well. When repairing a large defect of the esophageal hiatus during fundoplication, the surgeon may consider reinforcement of the repair with PTFE mesh.
