Long-term results of hiatal hernia mesh repair and antireflux laparoscopic surgery

Background

Laparoscopic antireflux surgery (LARS) represents the gold standard in the treatment of gastroesophageal reflux disease with or without hiatal hernia. It offers excellent long-term results and high patient satisfaction. Nevertheless, several studies have reported a high rate of intrathoracic wrap migration or paraesophageal hernia recurrence. To reduce the incidence of this complication, the use of prosthetic meshes has been advocated. This study retrospectively evaluated the long-term results of LARS with or without the use of a mesh in a series of patients treated from 1992 to 2007.

Methods

From November 1992 to May 2007, 297 patients underwent laparoscopic antireflux surgery in the authors’ department. Crural closure was performed by means of two or three interrupted nonabsorbable sutures for 93 patients (group A), by tailored 3 × 4-cm polypropylene mesh placement for 113 patients (group B), and by nonabsorbable suture plus superimposed tailored mesh for 91 patients (group C).

Results

The mean follow-up period for the entire group was 95.1 ± 38.7 months, specifically 95.2 ± 49 months for group A, 117.6 ± 18 months for group B, and 69.3 ±.17.6 months for group C. Intrathoracic Nissen wrap migration or hiatal hernia recurrence occurred for nine patients (9.6%) in group A, two patients (1.8%) in group B, and only one patient (1.1%) in group C. Esophageal erosion occurred in only one case (0.49%). Functional results and the long-term quality-of-life evaluation after surgery showed a significant and durable improvement with no significant differences related to the type of hiatoplasty.

Conclusion

Over a long-term follow-up period, the use of a prosthetic polypropylene mesh in the crura for hiatal hernia proved to be effective in reducing the rate of postoperative intrathoracic wrap migration or hernia recurrence, with a very low incidence of mesh-related complications.
