The therapeutic concept of programmed lavage has been established in t
he treatment of severe diffuse peritonitis. This treatment was given t
o 30 patients from January 1995 to February 1997. The total lethality
rate was 30% (11/30 patients). Ten patients had organ failure of three
or four organ systems at the time of first laparotomy. In this group
the lethality rate was 50%. On average 9.2 programmed relaparotomys we
re performed per patient. As early complications, small bowel fistulas
were observed in three patients, bleeding in three patients and probl
ems due to the laparostomy in four patients.
