目的

比较在直肠癌侧方淋巴结清扫中采用两种解剖入路的清扫效果。

方法

回顾性收集2019年1月至2022年1月接受全直肠系膜切除术并完成3年随访的123例直肠癌患者临床资料,根据侧方淋巴结清扫解剖入路不同分为筋膜组60例(筋膜导向解剖入路)与血管组63例(血管导向解剖入路)。采用SPSS25.0软件处理数据,手术相关指标、侧方淋巴结检出数等计量资料以(±s)表示,行独立样本t检验;阳性淋巴结检出率、术后并发症发生率等计数资料行χ2检验;生存分析采用Kaplan-Meier法并行Log-Rank检验。P<0.05为差异有统计学意义。

结果

两组患者术中出血量、手术时间、住院时间比较,差异无统计学意义(P>0.05);筋膜组侧方淋巴结检出数量多于血管组(P<0.05),两组阳性淋巴结检出率比较,差异无统计学意义(P>0.05);筋膜组患者术后排尿功能障碍、性功能障碍发生率低于血管组(P<0.05);Log-Rank检验结果表明,两组患者随访期间无进展生存率比较,差异无统计学意义(P>0.05)。

结论

筋膜导向入路与血管导向入路行直肠癌侧方淋巴结清扫的阳性淋巴结检出率、无进展生存率相当,但采用筋膜导向入路可检获更多侧方淋巴结,可减少患者术后排尿功能障碍及性功能障碍的发生。

Objective

To compare the effect of two anatomical approaches in lateral lymph node dissection of rectal cancer.

Methods

Clinical data of 123 patients with rectal cancer who underwent total mesorectal resection from January 2019 to January 2022 and completed 3-year follow-up were retrospectively collected.According to different anatomical approaches of lateral lymph node dissection, 60 patients were divided into fascia group (fascia-oriented anatomical approach) and 63 patients were divided into vascular group(vaso-oriented anatomical approach).SPSS25.0 software was used to process the data.Surgical indicators, the number of lateral lymph nodes detected and other measurement data were expressed as (x± s), and independent sample t test was performed.The positive lymph node detection rate and postoperative complication rate were analyzed by χ2 test.Kaplan-Meier method and Log-Rank test were used for survival analysis, and P<0.05 was considered statistically significant.

Results

There was no significant difference in intraoperative blood loss,operation time and hospital stay between the two groups (P>0.05).The number of lymph nodes detected in fascia group was higher than that in blood vessel group (P<0.05), and there was no significant difference in the positive lymph node detection rate between the two groups (P>0.05).The incidence of postoperative urinary dysfunction and sexual dysfunction in fascia group was lower than that in vascular group (P<0.05).Log-Rank test results showed that there was no significant difference in progression-free survival between the two groups during follow-up (P>0.05).

Conclusion

The positive lymph node detection rate and progression-free survival rate were similar between fascia-guided approach and vaso-guided approach in rectal cancer lateral lymph node dissection, but more lateral lymph nodes could be detected by fascia-guided approach, which could reduce the occurrence of postoperative urinary dysfunction and sexual dysfunction.
