[Histologic studies in the course of programmed peritoneal lavage].

A programmed peritoneal lavage was done in 20 patients. During this lavage, tissue samples were withdrawn for histological control. During the therapeutical lavage, the morphological signs of inflammation decreased. For the sanitation of peritonitis, the cause of the disease must be eliminated. The morphological signs of healing start during the first three days postoperatively. Peritoneal repair prevails after the second or third postoperative day. Peritonitis will be lethal without focus sanitation and with microorganisms resisting any therapy, although lavage having been done.
