Safety of primary anastomosis in emergency colo-rectal surgery.
BACKGROUND
The surgical management of left-sided large bowel emergency patients remains controversial. There has been an increasing trend towards primary reconstructive surgery. The main dilemma remains appropriate patient selection for primary anastomosis.


METHODS
The records of 323 patients who presented as acute emergencies and underwent surgery between January 1990 and December 2000 for left-sided colorectal cancer and diverticular disease were reviewed, to compare the outcome of resection and primary anastomosis with Hartmann's procedure. Patients were stratified into 3 groups according to whether the presentation was with localized or generalized peritonitis, or with obstruction.


RESULTS
Resection and anastomosis was carried out in 176 (55.7%) patients with a 30-day mortality of 5.7%. Anastomotic dehiscence occurred in 9 (5.1%) patients, with no difference between the three groups. Wound sepsis occurred in 8 (4.5%) patients, and the median hospital stay was 13 days. Hartmann's resection was associated with a higher incidence of systemic and surgical morbidity (39.5% and 24.3%, respectively). The mortality rates in those selected for primary anastomosis (5.7%) compared favourably with those undergoing Hartmann's resections (20.4%) (P < 0.001).


CONCLUSIONS
Emergency primary anastomosis in left-sided disease can be performed with a low morbidity and mortality in selected patients, even in the presence of a free perforation with diffuse peritonitis. Patients selected for staged resection, were those with major comorbid disease.
