Crura augmentation with Bio-A ® mesh for laparoscopic repair of hiatal hernia: single-institution experience with 100 consecutive patients

Abstract

Background

The potential utility of both non-absorbable and absorbable meshes to reinforce the esophageal hiatus and prevent recurrent hernia has been investigated in observational studies and a few randomized clinical trials. Use of absorbable mesh has been associated with lesser side-effects, but the long-term safety and effectiveness are still debated. This rather scanty clinical evidence is due to heterogeneity and bias regarding the type of mesh and operation used, the modalities of follow-up, and the reporting of objective results.

Objectives

The aim of the study was to assess safety, quality of life, and recurrence-free probability after laparoscopic repair of hiatal hernia reinforced with a synthetic absorbable mesh.

Methods

Observational, retrospective, single-center cohort study. All patients with hiatal hernia who underwent laparoscopic crura repair using a biosynthetic mesh (Gore Bio A^® tissue reinforcement, Flagstaff, AZ) were included. Pre- and post-operative symptoms were assessed with the GERD-HRQL questionnaire. Objective follow-up consisted of upper gastrointestinal endoscopy and barium swallow study.

Results

From September 2011 to March 2016, a total of 100 patients underwent hiatal hernia repair using a Bio-A^® mesh. All surgical procedures were completed laparoscopically. Postoperative morbidity rate was 10%. All patients had a minimum follow-up of 6 months, and the median follow-up was 30 (IQR = 22) months. No mesh-related complications occurred. The incidence of recurrent hernia ≥2 cm was 9%, and eight of the nine patients had a preoperative type III hernia. The median GERD-HRQL score was significantly reduced after operation (p < 0.001). The recurrence-free probability at 1 and 5 years was, respectively, 0.99 (CI 0.97–1.00) and 0.84 (CI 0.74–0.97), and no reoperation was required. No association was found between age, BMI, hernia size, previously failed surgical repairs and hernia recurrence.

Conclusions

The use of a synthetic absorbable mesh to reinforce the esophageal hiatus is safe and appears to be effective and durable over a medium-term follow-up.
