Abstract
Background: The aim of this population-based study was to analyse the relationship between intraoperative adverse events and outcome after anterior resection. Methods: All 140 patients who underwent elective anterior resection in Sweden between 1987 and 1995, and who died within 30 days, were compared with a group of 423 randomly selected patients who underwent the same procedure during the same interval but survived the operation. Intraoperative adverse events and intraoperative measures taken were analysed in relation to outcome of surgery. Results: Of those who died, 45·7 per cent had intraoperative adverse events compared with 30·3 per cent in the cohort group. Major bleeding, gross spillage of faeces, and two or more intraoperative adverse events were more common among those who died. When the anastomosis was considered unsatisfactory, it was more frequently reconstructed (restapled or completely resutured), with or without a temporary stoma, in those who survived. The use of a temporary stoma was comparable in the two groups when adverse events were present. Conclusion: Intraoperative adverse events were important contributors to morbidity and mortality. Complete reconstruction of an unsatisfactory anastomosis, with or without addition of a temporary stoma, was more frequently performed in the survivors, and may have diminished the risk of postoperative death.
