[Peritonitis: attempt to evaluate therapeutic surgical options].

The choice of optimal concept in the therapy of severe peritonitis is essential to outcome. In approximately 10-15% of patients suffering severe peritonitis, single-stage surgery is not sufficient and additional operative therapy is required. Different therapeutic strategies such as the open-package procedure, staged abdominal repair, and on-demand relaparotomy have been developed for these situations. However, it is difficult to compare the effectiveness of each regimen because stratification tools are lacking. This paper describes advantages and disadvantages of the various therapeutic options in peritonitis and their clinical implementation.
