[Technique of properitoneal hernioplasty. Unilateral reinforcement of the visceral sac with Mersilene giant prosthesis].

358 hernias of the groin (340 patients), predominantly recurrent and re-recurrent, were treated by this procedure, similar to bilateral hernioplasty, specifically developed for ambulatory surgery. There were 16 recurrences of which most were due to flaws in the original procedure. This was overcome by widening and extending the distal lateral corner of the mesh.
