Abstract:
Tension-free hernioptasty is a major method for treating inguinal hernia, characterizing by less wound, tension-free incision, sample processing, less dissection and separation, mild pain, rapid recovery, and short length of stay. In particular, transabdominal preperitoneal inguinal hernioplasty is considered as the most ideal method at physiologicoanatomical level. However, the effect of patch materials on postoperative recovery is generally ignored for a long time. Recent studies demonstrate that patch weight and mesh diameter are important factors for abdominal wall repairing and reconstruction. Polypropylene patch, characterizing by strong stability, high intensity, great unreactiveness, and sample processing, has become a major material for hernioptasty. However, there are still some problems of clinical application, including that polypropylene patch may induce intensive foreign body reaction and chronic inflammation as well as compliance decreasing of abdominal wall. Therefore, polypropylene patch should be chosen according to patient requirement, i.e., light, soft, and wide-aperture patch, so as to reduce onset of complication. Nerve and ligament tissues could be clearly observed from light and soft patch, and this might and prevent hurt by mistake, improve repairing operability, enhance correct putting of patch, and decrease incidence of pain. Furthermore, the structure was beneficial for in-growth of fiber tissue, longitudinal and transversal movement induced by body position alternation and muscle contraction, and reduction of discomfortableness.
