The results of colonic resections were investigated in 356 patients in
a retrospective analysis. Special attention was directed to the effec
tiveness of a transrectal tube, leading to decompression of the anasto
mosis for the first five days. Under elective conditions, the overall
complication-rate was 12.7%. In emergency cases, these complications w
ere 51.5% (one third of these cases had a decompression-tube). The cli
nical relevant leakage-rate under elective conditions ranged to 1.7%.
Postoperative mortality related to surgical complications turned out t
o be 1.5% under elective conditions. The emergency operations had a hi
gh mortality which ranged to approximately 15.2%. No patient with leak
age of a colorectal anastomosis died when the transrectal decompressio
n-tube was applied. Such a safety in anastomotic healing of colon and
rectum anastomoses can otherwise only be achieved by using the protect
ion of a diverting colostomy or ileostomy. The use of the transrectal
decompression-tube also avoids stomal complications and the second ope
ration. There is no indication for the decompression-tube in emergency
operations with purulent or faecal peritonitis. In these cases a fund
amentally different treatment is mandatory.
