Abstract: Objective To analyzethe surgical outcomes of laparoscopic distal gastrectomy plus No. 8p lymphadenectomy. Methods 182 patients who underwent laparoscopic distal gastric cancer surgery in our department from July 2019 to March 2021 were selected and randomly divided into No. 8p group （89 cases） and conventional group （93 cases）. The differences in operation time, blood loss, number of lymph nodes detected and recent surgical complications between the two groups were compared, and the relationship between the number of lymph nodes detected in No. 8p group and other regions was further analyzed. Results There was no significant difference in operation time, blood loss and recent complications between the two groups （P>0.05）, but more operation time and lymph nodes were detected in the dissection group （P<0.05）. In the 89 patients in the No. 8p group, only 5 cases （5.6%） had lymph node metastasis. Further analysis of the relationship with the number of lymph nodes detected in other regions showed that there was a significant difference in the number of lymph nodes detected in No.12a groups （P<0.05）. Conclusion For laparoscopic distal radical gastrectomy, lymph node dissection in Group No. 8p is safe and feasible, and can improve the quality of lymph node dissection in groups No. 12a.

摘要： 目的 探讨腹腔镜下清扫No. 8p组淋巴结对远端胃癌根治手术进程的影响。方法 选取2019年7月至2021年3月在我科接受腹腔镜远端胃癌手术的患者182例,随机分为清扫No. 8p组89例,常规组93例,对比两组在手术时间、出血量、淋巴结检出数量、近期手术并发症、术后住院天数、术后淋巴结检出数量等方面差异,进一步分析清扫No. 8p组淋巴结与其他各组淋巴结检出数量的关系。结果 两组在出血量、近期手术并发症、术后住院天数方面差异无统计学意义（P>0.05）,清扫组所需手术时间较长（P<0.05）且有更多的术后淋巴结检出数量（P<0.05）。清扫组89例患者中No. 8p组淋巴结转移者仅5例（5.6%）,进一步分析与其他各淋巴结检出数量的关系显示No. 12a组淋巴结检出数量有统计学差异（P<0.05）。结论 对于腹腔镜远端胃癌根治术中清扫No. 8p组淋巴结安全可行,并可提高No.12a组淋巴结清扫质量。
