Abstract:
Objective:To explore the application effect of nano-carbon in single port laparo-scopic transanal total mesorectal resection in the treatment of low rectal cancer.Methods:A total of 96 patients underwent single-port laparoscopic transanal mesorectal resection were selected and randomly divided into observation group(preoperative nano-carbon suspension injection)and control group,48 cases in each group based on the random number table method.After the operation,the number of lymph nodes dissected was recorded,and the number of dark-stained lymph nodes was detected,and pathological examination was performed to confirm the metastasis of each lymph node.Results:The average number of lymph nodes detected in the observation group(18.46±3.52 vs 10.63±1.95)was significantly higher than that in the control group,and the difference was statis-tically significant(P＜0.05).The rate of lymph node metastasis detected in the observation group(12.19％)was higher than that in the control group(9.41％),but the difference between the two groups was not statistically significant(P＞0.05).The metastasis rate of black-stained lymph nodes(88/611,14.40％)was significantly higher than that of non-stained lymph nodes(20/275,6.18％)and the control group(48/510,9.41％),and the difference was statistically significant(x2=9.007,6.495,P=0.003,0.011).Conclusion:Preoperative application of nano-activated carbon suspension injec-tion can increase the number of lymph nodes and the detection rate of lymph node metastasis in pa-tients undergoing single-port laparoscopic transanal mesorectal resection,which can ensure the ac-curacy of pathological staging.It can be used in clinical rectal cancer.The treatment is of guiding sig-nificance.
