Abstract:
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.
