Combined gastrointestinal and abdominal aortic aneurysm operations

Experience with gastrointestinal surgical conditions in 154 consecutive aneurysm operations at St Vincent's Hospital, Sydney, over 5 years (1982-86) is reported. Seventeen patients (11%) had coincidental gallstones, and six patients had other gastrointestinal conditions. Postoperative gastrointestinal complications occurred in eight patients. The overall in-hospital mortality rate was 7.8%. Four of the 12 deaths were associated with gastrointestinal problems, but these complications first developed after aneurysm surgery in three patients and could not have been avoided by a concurrent operation. The management of gastrointestinal pathology in association with the treatment of abdominal aneurysm is reviewed. The coincidence of these disorders is not sufficiently frequent to allow valid comment on the probability of successful outcomes, but the risks posed by surgically untreated gastrointestinal conditions are low, so that secondary gastrointestinal procedures should be avoided in most aneurysm operations.
