Definitive one-stage emergency large bowel surgery.

During a 30-month period, 126 operations for emergency large bowel conditions were performed: 57 were for colonic carcinoma, 26 for acute diverticulitis, 14 for colonic ischaemia, 13 for complications of inflammatory bowel disease, and 16 for other conditions. Sixty-eight patients had peritonitis. One hundred and ten patients (87.3 per cent) underwent immediate resection. Of these, 83 (65.9 per cent of the overall group) had colonic resection with primary anastomosis but without a colostomy, 56 of which were left-sided colonic resections. Excluding 9 of the 68 patients with peritonitis, who had a total colectomy, 66 per cent also underwent resection, anastomosis and no colostomy. Total group mortality was 14.3 per cent: 12.7 per cent in the immediate resection group, 9.6 per cent in those with primary anastomosis and no colostomy, 5.2 per cent in the group with peritonitis undergoing resection and anastomosis, and 25 per cent in those having non-resectional surgery. Complications included an overall wound infection rate of 10.3 per cent and a clinical anastomotic leak rate of 7.2 per cent in those who had anastomosis without colostomy. Our results suggest that resection and primary anastomosis can be performed with acceptable morbidity and mortality in a high proportion of cases of emergency large bowel conditions, irrespective of underlying pathology, site of disease or the presence of peritonitis.
