Large Hiatal Hernia

The purpose of the study is to evaluate the success of hiatal hernia repairs in patients with large (\>5cm) or paraesophageal hernias when Ovitex LPR mesh used during the repair.

The large hiatal hernia (LHH) now represents approximately 50% of laparoscopic antireflux surgical practice. In a non-comparative retrospective study of 399 patients operated for LHH with onlay patch of a bioprosthetic absorbable (Gore® Bio-A® HH0710) mesh with a mean follow-up of 44 months, 16% had a symptomatic recurrence with 7,9% requiring reoperation, one patient had oesophageal stenosis. No comparative effectiveness data exist to date. Hypothesis: the incidence of postoperative hiatus hernia would be reduced by the addition of biosynthetic absorbable mesh reinforcement to a standardized suture repair technique, as compared to laparoscopic repair without mesh, without increasing the risk of complications. The main objective is to compare the radiologic recurrence rate at 2 years between standardized herniorrhaphy with onlay biosynthetic absorbable mesh repair versus standardized herniorrhaphy with no mesh in symptomatic LHH.
