目的总结老年人大肠癌并发急性肠梗阻的I期切除吻合手术治疗方法及临床疗效。方法根据手术方法不同将我院收治的90例老年大肠癌并急性肠梗阻患者的临床资料分为对照组和观察组。其中对照组38例行Miles手术;观察组52例行I期肠切除吻合术,观察两组患者治疗效果及并发症发生率。结果观察组并发症发生率明显低于对照组,差异有统计学意义;术后观察组随访42例,对照组随访33例,观察组术后半年、1年生存率高于对照组,差异有统计学意义。结论对老年大肠癌并发急性肠梗阻患者施行I期肿瘤切除吻合术,与Miles手术相比,疗效和安全性较好,确切效果值得进一步研究。 Objective To summarize the surgical treatment of I-phase resection and anastomosis of colorectal cancer complicated with acute intestinal obstruction in the elderly and its clinical effect. Methods The clinical data of 90 elderly patients with colorectal cancer and acute intestinal obstruction admitted to our hospital were divided into control group and observation group according to different surgical methods. Among them, 38 patients in control group underwent Miles operation; 52 patients in observation group underwent I-phase intestinal resection and anastomosis. The therapeutic effect and complication rate were observed in both groups. Results The incidence of complications in the observation group was significantly lower than that in the control group, the difference was statistically significant; 42 cases were followed up in the observation group and 33 cases were followed up in the control group. The 6-year and 1-year survival rates in the observation group were higher than those in the control group Statistical significance. Conclusions The I-stage tumor resection and anastomosis in elderly patients with colorectal cancer complicated with acute intestinal obstruction, compared with the Miles operation, the efficacy and safety is good, the exact effect deserves further study.
