Mesh Crural Repair of Large Paraesophageal Hiatal Hernias

Surgical repair is indicated in patients with paraesophageal hernias but is associated with a high recurrence rate. Our objective was to assess the safety and efficacy of mesh reinforcement of the crural closure in laparoscopic paraesophageal hernia repair. We conducted a 7-year retrospective review of all patients undergoing laparoscopic paraesophageal hernia repair with or without use of mesh. The main outcome measures were use of mesh, reason for use, age, sex, preoperative symptoms, length of operation, length of hospital stay, postoperative complications, and long-term follow-up conducted by physician interview. Twelve patients were repaired with mesh (Group A) and 12 without (Group B). Age, sex, operating time, length of hospital stay, and postoperative complications were similar in both groups. In Group A two patients required an interposition graft and ten required mesh reinforcement of the crural closure. One Group A patient developed an early recurrence requiring a reoperation, and one Group B patient developed a gastric leak where the fundus was sutured to the crura. The remainder of the patients experienced resolution of their symptoms at 2 weeks follow-up. Long-term follow-up (average 37 months) showed one Group B patient with a recurrence of reflux symptoms, but an upper gastrointestinal study showed no recurrence of hernia. All others remained asymptomatic. We conclude that the use of mesh in laparoscopic repair of large paraesophageal hernias appears safe and may reduce recurrence.
