Mesh-associated complications in minimally invasive ventral mesh rectopexy: a systematic review

Abstract

BackgroundVentral mesh rectopexy (laparoscopic and robotic) is a common and well established treatment of rectal prolapse. Although described as safe and effective, complications, especially mesh-associated ones are often mentioned. Additionally, there is no consensus regarding the mesh type and fixation method as well as the materials used for this purpose. The aim of this systematic review was to identify the total amount of complications and of those the mesh-associated ones.MethodsPubmed, Web of Science and Cochrane Central Register were screened for complications in general and in detail regarding the mesh(es) and a systematic review was performed.ResultsFollowing qualitative evaluation, 40 studies were identified for further investigation. Across 6269 patients, complications were found in 9.2% (622 patients). Mesh-related complications were described in 1.4% (88 patients) of which 64.8% were erosions, 11.4% fistulas and 13.6% mesh releases. The complication rate according to the different materials were low with 1% in biological and synthetic meshes and 1.8% in not further described or mixed mesh type. Non-absorbable material to fixate the mesh was most frequently used to fixate the mesh.ConclusionLaparoscopic ventral mesh rectopexy is a safe operation with a low-complication rate, regardless of mesh type.
