Brief Summary
The major long term complication of abdominal wall closure after a median laparotomy is the development of an incisional hernia. Several suture technique and suture material have been used but the incidence of this complication still lies between 9 -20%. Synthetic suture material which have become available over the last decades have the advantage that they are degraded by the body system and fully absorbed within 70-180 days; however they loss 50% of their initial strength already after 14-30 days and may not be the optimal suture material for abdominal wall closure. A new suture material (Monomax®) was developed with an extra-long absorption profile, high elasticity and with a superior initial strength. Therefore, the ESTOIH-Study was designed to investigate the influence of the stitch length on the occurrence of incisional hernia using the extra-long term absorbable, elastic, monofilament suture (Monomax®).
