The problem of mesh shrinkage in laparoscopic incisional hernia repair

摘要: Introduction Mesh shrinkage is one of the unsolved problems laparoscopic hernia repair. Methods A literature search via online database DIMDI and Pubmed with key words "ventral hernia, incisional repair, mesh shrinkage" was carried out. Surface volume changes caused by insufflation abdomen were estimated a simplified hemisphere model. Results Eleven experimental 3 clinical studies published data referring to intraperitoneally placed meshes. Polypropylene meshes showed in order 3.6-25.4 %, PTFE 4.0-51.0 coated polypropylene polyester 6.1-33.6 %. Three confirmed these (5-57 %). Since gas essential for surface abdominal wall are intraoperatively significantly increased. An additional l increases about 80 This more than rates can compensate. Consequences The surgeon has anticipate significant measurement proper dimensions consider insufflated expected shrinkage.
