[Problems with definitive abdominal closure using "zipper" and after "left open abdomen"].

There are many problems associated with definitive closure of "left open abdomen" and abdominal zip. If the assumption can be made that after an operation multiple lavages will be necessary, we recommend a transverse laparotomy because there is much less retraction of the abdominal wall than with longitudinal laparotomy. Definitive closure with split-skin is inadequate as the missing elasticity especially with underlying small intestine loops leads to tearing, besides the mechanical properties of a thiersch as replacement for the abdominal wall is bad. Should the intra-abdominal infection have affected the abdominal wall itself, the implantation of an abdominal zip is useless as it tears away in a short time. Primary laparostoma is then the therapy of choice. The earlier definitive closure is planned, the easier this can be done. Prognosis does not depend on the way of temporary closure but on underlying pathology and on the possibility of resolving problems in adequate time.
