The authors evaluate two groups of patients after laparotomy where during the postoperative period complete dehiscence of the laparotomic wound occurred. In the first group A the laparotomies were closed in anatomical layers by individual silon stitches, in group B for closure a single layer continuous PDS loop suture was used. After introduction of this technique the percentage of dehiscent laparotomies declined from 2,2% to 1,2%.
