结肠肿瘤并发急性肠梗阻是外科常见急腹症之一 ,约占肠梗阻发生率的 7%～ 2 9% [1] ,尤其是低位大肠梗阻约 30 %～ 70 %是大肠癌所致[2 ] 。在治疗上对右半结肠肿瘤致梗阻行Ⅰ期切除吻合已取得一致意见 ,而对左半结肠肿瘤致梗阻术式的选择至今仍有争论 ,多数学者主张分期手术。 Colonic neoplasms complicated by acute intestinal obstruction is one of the common surgical acute abdomen, accounting for about 7% to 29% of the incidence of intestinal obstruction [1], especially low colon obstruction of about 30% to 70% due to colorectal cancer [2 ]. In the treatment of right hemicoid tumor caused by obstruction line I resection and anastomosis have reached consensus, and the choice of obstruction caused by left colon cancer is still controversial, most scholars advocate staging surgery.
