The aim of this study was to evaluate the immediate and short-terme follow-up results of one-stage subtotal or total colectorny and artastomosis for patients with malignant Left colon obstruction. The study comprised 21 patients (10 males and 11 females) with age range of 36-81 years; presented by acute large bowel obstruction with clinical and radiological evidence of obstruction. The choice of the extent of resection was determined by the extent offecal load, the presence of colonic perforation, serosal tears of the cecum and/or massive _colonic distension with concomitant ischemio.; the presence of these features in a hemodynarnically stable patient favored subtotal or total colectomy and ileo-colic or ileorectal anastomosis . The site of obstruction was at the sigmoid colon in 9 patients (42.9%), rectosigmoicl in 8 patients (38.1%), splenic flexure in 3 patients (14.3%) and descending colon in one patient (4.7%). Ileosigmoid anastomoses were done in 13 patients (61.9%) and 8 patients (38.1%) had ileorectal anastomoses. The mean operative time was 201+33.2; range: 150-270 minutes, the mean operative blood loss was 683.3+408.2; range: 250-1800 cc; 11 patients (45.8%) required blood transfusion with a mean number of blood bags used was 2.8+1.2; 1-5 bags. Oral feeding was resumed after a mean period of 4.9+0.9; range: 4- 7 days and the mean postoperative hospital stay was 10+2.2; range: 8- 18 days. Overall, after 12-months follow-up only one patient had anastomotic line recurrence with a recurrence rate of 4.75%, one patients died of acute liver failure secondary to hepatic metastasis with mortality rate of 4.75% and 19 patients had follow-up free of morbidity with no local recur-rence or metastasis and a follow-up free rate of 90.5%. Thus, it could be concluded that one-stage subtotal or total colectomy and ileo-colic or ileorectal anastomosis are safe procedure with satisfactory outcome for management of obstructing malignant lesions of the left colon.
