Restorative rectal resection: an audit of 220 cases.

Two hundred and twenty consecutive, unselected cases of restorative rectal resection are reported. The operative mortality was 8.3 per cent; 3.5 per cent in patients less than 70 years old and 13 per cent over that age. Leakage at the colorectal suture line was an intractable problem, uninfluenced by anastomotic technique, but the introduction of antimicrobial prophylaxis as a routine was followed by a statistically significant reduction in the leak rate. Postoperative rectal function was satisfactory but temporary stenosis at the suture line was not uncommon. In only one case was it permanent, requiring regular dilatation. Recurrence of malignant disease occurred in 50 per cent of cases followed for at least 2 years; 35 per cent general disease, 15 per cent localized to the pelvis. These figures do not differ significantly from those following total rectal excision, which is now necessary in only 1 in 10 cases where the growth lies within 10 cm of the anus.
