吻合器经肛门行直肠黏膜选择性切除钉合术治疗低位直肠良性肿瘤疗效分析

Application of tissue-selecting therapy stapler in local excision of rectal benign tumors

目的研究低位直肠良性肿瘤应用吻合器经肛门行直肠黏膜选择性切除钉合术(TST)的安全性和长期疗效。方法收集162例低位直肠良性肿瘤的患者,其中90例行TST治疗(TST组),72例行传统经肛门肿物切除术(对照组),就两组切除肿瘤的完整程度,术中、术后并发症和复发率进行对比统计分析。结果 TST组均顺利切除肿瘤,手术时间、术中出血量、住院时间显著低于对照组(P<0.05),切除组织的完整程度显著高于对照组(P<0.05),复发率显著低于对照组(P<0.05),术后并发症差异无显著性意义(P>0.05)。结论应用TST治疗低位直肠良性肿瘤具有较好的疗效和较低的复发率。

Objective To assess the safety and long - term effectiveness of tissue - selecting therapy （TST） for benign tumor in anorectum, in comparison with mass resection therapy. Methods 162 Patients with benign tumor of anorectum were divided into the therapy group and the control group. 90 patients were treated with TST, while 72 patients had anal mass resection therapy. Tumor integrity, intraoperative and postoperative complications, and recurrence rate were compared between the two groups. Results All tumors in the treatment group were completely resected. The operation time, intraoperative bleeding, hospital stay and the recurrence rate were significantly lower than the control group （P 〈 0.05）. The tumor integrity was higher than the control group （P 〈 0.05）. There was no significant difference in the postoperative complications between the two groups （ P 〉 0.05 ）. Conclusion TST has better efficacy and lower recurrence rate in the treatment of benign anorectal tumors.
