目的：通过对比分析国产与进口内镜吻合器在腹腔镜辅助直肠癌根治（Dixon）术中的应用效果，探讨国产内镜吻合器的安全性及可行性。方法收集2012年2月~2013年12月期间在本院确诊为直肠癌需行腹腔镜辅助直肠癌根治的病例64例，随机分为研究组35例和对照组29例。术中研究组使用瑞奇外科器械（北京）有限公司生产的ENDO RLC通用内镜直线切割吻合器及一次性钉匣和一次性使用RCS系列端端吻合器，对照组使用强生医疗器材有限公司已广泛应用于临床的对应产品。对比分析两组病例术中及术后情况。结果所有病例均取得了满意的治疗效果。两组间的手术时间、术中吻合成功率、术后并发症（吻合口出血、吻合口瘘、吻合口狭窄）发生率无统计学差异（P>0.05），而研究组术中所用内镜吻合器的平均费用低于对照组（6604.31±699.95 vs 7822.28±576.98），有明显统计学差异（P<0.05）。结论瑞奇外科器械（北京）有限公司生产的国产内镜吻合器应用于腹腔镜辅助直肠癌根治手术中是安全、有效的，并且还可相对降低手术费用，值得临床推广应用。%Objective To investigate the safety and feasibility of domestically made endoscopic stapling instrument in laparoscopic assisted rectal cancer resection (Dixon). Methods Sixty-four patients with rectal cancer were randomly divided into the research group (35 cases) to receive laparoscopic assisted rectal cancer resection using ENDO RLC general endoscopic linear cutter and single-use loading unit and circular staplers with staples (from REACH medical equipment co.LTD) and the control group (29 cases) to receive surgery with the corresponding products widely used (fom Johnson & Johnson Mdical Euipment C.Ltd). The clinical data of the two groups were compared. Results Satisfactory therapeutic effects were obtained in all the cases. The two groups showed no significant differences in the operative time, intraoperative anastomosis success rate, or postoperative complications (anastomotic bleeding, leakage, or stricture) between the two groups (P>0.05), but the average cost of endoscopic stapling instrument was significantly lower in the research group (6604.31 ± 699.95 vs 7822.28 ± 576.98 RMB Yuan, P<0.05). Conclusion The domestic endoscopic stapling instrument is safe, effective and less costly for laparoscopic assisted rectal cancer resection.
