Methods: The clinical data of 34 patients with left colon cancer and acute colonic obstruction in our hospital were analyzed retrospectively. The patients were treated by intraoperative colonic lavage and stage Ⅰ resection and anastomosis. Results: In this group, 3 cases were complicated with incision infection and 1 case was anastomotic leakage. After treatment, no deaths were found.
