Adverse effects of polyvinylidene fluoride-coated polypropylene mesh used for laparoscopic intraperitoneal onlay repair of incisional hernia

Abstract

Abstract Background Polyvinylidene fluoride-coated polypropylene meshes have been developed specifically for intraperitoneal onlay mesh repair. They combine a macroporous design with biomechanical characteristics compatible with the abdominal wall and are reported to have favourable antiadhesive properties. This retrospective study reports complications related to one of these materials, DynaMesh®. Methods Twenty-nine patients underwent intraperitoneal onlay mesh repair with DynaMesh® at one of two hospitals. Patients characteristics, surgical procedures and postoperative analgesia were comparable at both sites. Results Six patients developed DynaMesh®-related complications that required surgical reintervention by laparotomy within 1 year of operation. Surgical reintervention was for adhesions in five patients and the mesh had to be explanted in three. One mesh was explanted because of early infection. Adhesions to DynaMesh® were found in two patients who had surgery for unrelated reasons. Conclusion Laparoscopic intraperitoneal onlay DynaMesh® repair was associated with a high rate of complications.
