Abstract

Background

The aim of this population-based study was to analyse risk factors for death within 30 days after anterior resection of the rectum.

Methods

Between 1987 and 1995 a total of 6833 patients underwent elective anterior resection of the rectum in Sweden. One hundred and forty of these patients died within 30 days or during the initial hospital stay. These patients were compared with a randomly chosen cohort of 423 patients who underwent the same operation during the same interval, and were alive after 30 days and discharged from hospital. The association between death and 12 putative risk factors was studied.

Results

The mortality rate after elective anterior resection was 2·1 per cent (140 of 6833). The incidence of clinical anastomotic leakage was 42·1 per cent (59 of 140) among those who died and 10·9 per cent (46 of 423) in the cohort group. Multivariate regression analysis identified clinical leakage, increased age, male sex, Dukes' ‘D’ stage and intraoperative adverse events as independent risk factors for death within 30 days.

Conclusion

Clinical anastomotic leakage was a major cause of postoperative death after anterior resection.
