目的观察双荷包吻合术在低位直肠癌手术中的应用价值。方法 215例低位直肠癌随机分为两组,均行手术治疗,观察组115例采用全直肠系膜切除术(TME)+双荷包吻合术,对照组100例采用TME+双吻合器吻合术,术后分别观察疗效。结果观察组吻合口瘘发生率为1.7%,低于对照组的9.0%,差异有统计学意义(χ2=5.809,P=0.016)。发生吻合口瘘的病例经积极保守治疗后均痊愈。结论双荷包吻合术能够降低低位直肠癌保肛手术术后吻合口瘘发生率。 Objective To observe the value of double blepharoplasty in low rectal cancer surgery. Methods A total of 215 patients with low rectal cancer were randomly divided into two groups. All patients underwent surgical treatment. 115 patients in the observation group were treated with total mesorectal excision (TME) and double blepharoplasty, and 100 patients in the control group were treated with TME plus double stapling anastomosis. Observe the curative effect separately. Results The incidence of anastomotic leakage was 1.7% in the observation group and 9.0% in the control group. The difference was statistically significant (χ2=5.809, P=0.016). Cases of anastomotic fistula recovered after active conservative treatment. Conclusion Double blepharoplasty can reduce the incidence of anastomotic leakage after anus-preserving operation in low rectal cancer.
