【摘要】 目的：探讨在（疾病）诊断相关分类（diagnosis related groups,DRGs）形势下，腹腔镜结直肠癌经自然腔道取标本（NOSES）手术方式改进及其可行性。方法：回顾性分析安阳市肿瘤医院2019年2月至2021年2月实施DRGs的42例改进后的腹腔镜结直肠癌NOSES术，并与同期进行常规腹腔镜结直肠癌手术的238例患者在费用、治疗结果、并发症等方面相比较。结果：NOSES改进组42例患者DRGs控费成功率为95.2%(40/42)，与常规腹腔镜组在DRGs费用及近期并发症发生率方面无显著性差异（P>0.05）。结论：腹腔镜结直肠癌NOSES改进手术可以达到DRGs费用标准，手术安全可靠，应用双7号丝线代替部分直线切割闭合器是可行的。更多还原

【Abstract】 Objective: To investigate the improvements and feasibility associated with advances in natural orifice specimen extraction surgery(NOSES) for colorectal cancer under diagnosis related groups(DRGs). Methods: A retrospective analysis of 42 patients with modified laparoscopic colorectal cancer NOSES who underwent DRGs at Anyang Tumor Hospital from February 2019 to February 2021 was carried out. The results were compared with those of 238 patients who underwent routine laparoscopic colorectal cancer surgery at the same time in terms of cost, treatment outcome and complications. Results: The success rate of DRGs in the improved group was 95.2%(40/42). There was no significant difference in DRGs cost and short-term complication rate between the two groups(P>0.05) Conclusions: The improved laparoscopic operation for the NOSES of colorectal cancer can meet the cost standard of DRGs, and the operation is safe and reliable. It is feasible to use double no. 7 silk thread instead of partial linear cutting closers.更多还原
