P6 HIATAL HERNIA REPAIR BY TENSION-FREE MESH CLOSURE OR SIMPLE SUTURING OF THE DIAPHRAGMATIC HIATUS
Abstract Aim To assess the anatomical and functional results of the use of a mesh for the repairing of hiatal hernia in patients with gastro-esophageal reflux disease (GERD) Background & Methods In hiatal hernia repair during antireflux surgery, less focus has traditionally been directed towards the restoration of the diaphragmatic hiatus. In other types of hernia repair, the use of a mesh-reinforced, tension-free technique has been shown to be associated with reduced recurrence rates. Patients (n=159) undergoing Nissen fundoplication for gastro-esophageal reflux disease were randomized to closure of the diaphragmatic hiatus with either crural sutures alone (n=77) or tension-free closure with a non-absorbable mesh (Crurasoft®, n=82). Primary outcome was radiologically verified recurrent hiatal hernia. Secondary outcomes were intra-and postoperative complications and courses, symptomatic recurrence, use of PPI, postoperative oesophageal acid exposure and Quality of Life. Results At 3 years recurrence rates were 12 % and 9 % in the mesh and suture groups respectively (p=0,61). Control of GERD symptoms, use of PPI and oesophageal acid exposure did not differ between groups. At the same time obstructive eating complaints were reduced in both groups compared to the preoperative setting (p<0.05) but more patients scored dysphagia for solid food after mesh closure (p=0,027). Quality of life scores were significantly improved throughout the follow up without differences between groups. Conclusion Tension-free crural repair with non-absorbable mesh does not reduce the incidence of recurrent hiatal hernia compared to crural sutures alone in GERD patients undergoing total fundoplication. This, together with the finding of increased dysphagia at 3 years postoperatively, suggests that mesh closure cannot be recommended for routine use in laparoscopic hiatal hernia repair for GERD.
