15％以上的结肠癌并发穿孔或梗阻，由此而实行的急症手术具有高的并发症发病串、死亡率和低的治愈率。出于安全性考虑，手术程序总体上最小化即传统的三期手术（给肠造口术→癌切除术→造口关闭术），然而它已被二期（Hartmann’s）或一期切除术逐渐取代。为了研究手术方式变更 More than 15% of colon cancers are associated with perforation or obstruction. The emergency operations performed thereby have high incidence of complications, mortality, and low cure rate. For safety reasons, the surgical procedure is generally minimized, ie the traditional three-stage operation (gimmostomy → cancer resection → ostomy closure), but it has been gradually improved by the second phase (Hartmann’s) or primary resection. replace.
