目的探讨结肠顺行灌洗在左半结肠癌合并急性梗阻采用一期吻合的效果。方法分析我科34例左半结肠癌并急性肠梗阻患者术中采用结肠顺行灌洗后行一期切除吻合资料。结果34例患者均治愈出院,切口感染5例,2例肺部感染,无一例出现吻合口漏。结论掌握手术适应症,术中正确使用结肠顺行灌洗法,左半结肠癌并急性肠梗阻行一期切除吻合是可行的。 Objective To investigate the effect of anastomosis of colonic cisplatin in the first half of colon cancer with acute obstruction. Methods A total of 34 cases of left colon cancer with acute intestinal obstruction in our department were treated with colonic lavage followed by one-stage resection and anastomosis. Results All 34 patients were cured, 5 were incisional wound infection and 2 were pulmonary infection. None of them had anastomotic leakage. Conclusions It is feasible to master the indications for surgery, correct laparoscopic colonic irrigation in operation, and primary resection and anastomosis of left colon cancer with acute intestinal obstruction.
