title: Staged resection or primary anastomosis for obstructing lesions to the left colon.
abstract: The management of obstructing left-sided colonic and rectal lesions has traditionally been by a staged procedure. The introduction of 'on-table lavage', has made primary resection and anastomosis of the large bowel feasible for patients presenting as emergencies. We have studied the perioperative course of 28 patients who presented with left colonic obstruction to determine whether primary anastomosis conferred additional morbidity. The patients ranged in age from 29 to 89 years (mean 66 years) at presentation. The ASA status of patients was comparable in both groups (Table 1). Fourteen patients underwent resection, on-table lavage, and primary anastomosis (PA) and 14 a Hartmann's procedure (HP). The mean operative time for the PA procedure was 200 minutes compared to 110 minutes for the HP group. There was no significant difference in the postoperative complication rate nor mean hospital stay rate for the primary procedures between the two groups. There was no clinical anastomotic leak in patients undergoing primary anastomosis. However secondary surgery for patients undergoing colorectal reconnection conferred added morbidity for patients who had a HP. We conclude that resection, on-table lavage, and primary anastomosis is safe in the management of left-sided colonic obstruction and in most cases is the treatment of choice.
