Robotic Fundoplication for Gastroesophageal Reflux Disease and Hiatal Hernia: Initial Experience and Outcome.

Gastroesophageal reflux disease, associated with sliding or large paraesophageal hiatal hernia, represents a common clinical presentation. The repair of large paraesophageal hiatal hernias is still a challenge in minimally invasive surgery. Between March 2014 and August 2016, 50 patients (18 males and 32 females) underwent robotic fundoplication (17 sliding and 33 paraesophageal hernias). The mean age of the patients was 58 years. Biosynthetic mesh was used in 28 patients with paraesophageal hernia. The mean operative time was 115 minutes (90-132) in the sliding hiatal hernia group, whereas it was 200 minutes (180-210) in the paraesophageal hiatal hernia group. The mean hospital stay was 36 hours (24-96). Eight patients experienced mild dysphagia which resolved after four weeks. No postoperative dysphagia was recorded at 30-month median follow-up. We experienced one recurrence in the sliding hernia group and two recurrences in the paraesophageal hernia group, with two patients treated robotically. Robotic fundoplication in treating sliding hiatal hernia is feasible and safe but is more challenging in the large paraesophageal group. Improved patient outcomes hinge on the operative technique used and increasing surgeon experience. The increased dexterity that robotic surgery affords enables the esophageal surgeon to more adeptly apply the traditional principles of laparoscopic fundoplication.
