Morbidity and mortality of various surgical therapy protocols for larg
e bowel carcinoma were analysed in 1270 patients and compared to data
from other working groups. We found a decline of mortality rates, espe
cially after abdomino-perineal rectum extirpation. The infection rate
of the sacral wound is. however, still as high as it used to be. The a
nastomotic insufficiency rate after anterior rectum resection is depen
ding on location of the anastomoses, amounting to about 7-8 % after ma
nual suture as well as after stapled anastomosis. In colon surgery gen
eral complications are more frequent than surgical ones.
