Objective  To analyze the feasibility of stage Ⅰ resection and anastomosis for left colon cancer with acute intestinal obstruction.

  Methods  The clinical data of 46 patients with left colon cancer complicated with acute intestinal obstruction were retrospectively analyzed, among whom 23 treated by staged operation were as control group, and the rest 23 patients treated by stage Ⅰ resection and anastomosis were as experimental group. The therapeutic effect was recorded.

  Results  The operation time, time to recovery of gastrointestinal function and hospitalization time in the experimental group were shorter than that in the control group (P < 0.05). There were no significant differences in the number of lymph node clearance, the incidence of complications such as abdominal infection and anastomotic leakage between the two groups (P>0.05). Significant differences in incision infection and total incidence of complications between the two groups were observed(P < 0.05).

  Conclusion  Stage Ⅰ resection and anastomosis is safe and feasible in the treatment of left colon cancer complicated with acute intestinal obstruction, which can relieve the pain of patients, shorten the hospitalization time and improve the quality of life.
