Objective: The aim of the present study was to review our experience in the surgical management of patients with obstructing colorectal cancers over an 11‐year period, 1987–1997. Patients and methods: Retrospective review of case records of 275 patients (male: 177; female 98) who had undergone emergency surgery for obstructing colorectal cancers was performed. Tumours proximal to splenic flexure were defined as proximal tumours while those at or below the splenic flexure were defined as distal tumours. Results: The obstruction was caused by proximal tumours in 88 (32%) patients. The resection rate and the primary anastomotic rate were higher for proximal tumours compared with distal tumours (95.5% vs 85.6%, P = 0.014; 92% vs 30.5%, P < 0.001). For distal tumours, stoma rate was found to be influenced by the following factors: preoperative albumin level, duration of observation after admission, operating surgeons’ years of experience, bowel perforation and site of the obstructing tumour. Multivariate analysis disclosed that surgeons’ experience was the only independent factor predicting stoma formation. The in‐hospital mortality and the anastomotic leakage rates were 15.3% and 5.6%, respectively. Tumour stage was the only prognostic factor affecting the disease‐free survival after curative resection. The 5‐year disease‐free survival rates for Dukes’ B and C disease were 66% and 37.2%, respectively. Conclusions: Tumour stage was a significant prognostic factor for patients with obstructing colorectal cancers. Emergency surgery for distal tumours should preferentially be performed by more experienced surgeons in order to achieve a higher anastomotic rate.
