Abstract：Objective To investigate the application of endoscopically injected carbon nanoparticles combined with titanium clips in laparoscopic radical resection of colorectal cancer.Methods 100 patients who underwent laparoscopic radical resection of colorectal cancer admitted to Pingxiang Second People's Hospital from January 2023 to June 2024 were included.The patients were divided into an experimental group and a control group using random number table method,with 50 patients in each group.Colonoscopy was performed before operation in both groups,and endoscopic injection of nano-carbon combined with a titanium clip was used before the operation in the experimental group.The localization effect,the total time of operation,the time of probing the lesion during operation,the amount of blood loss,the number of days in the hospital,the incidence of postoperative complications,and the lymph nodes were compared between the two groups.Results The coincidence rates of the ascending colon,hepatic flexion,transverse colon,splenic flexion,descending colon,sigmoid colon,and rectum in experimental group were higher than those in the control group,and the difference was statistically significant(P<0.05).The total operation time,intraoperative lesion exploration time,operative blood loss,and hospitalization days of the experimental group were lower than those of the control group,and the differences were statistically significant(P<0.05).The average number of lymph nodes detected in the experimental group and the average number of tiny lymph nodes detected were higher than those in the control group,and the difference was statistically significant(P<0.05).Conclusion In laparoscopic radical resection of colorectal cancer,nano-carbon combined with titanium clips can accurately locate colorectal cancer,shorten the total time of surgery and intraoperative lesion exploration time,reduce the amount of surgical bleeding,shorten the length of hospital stay,guide the selection of surgical incision,increase the number of lymph nodes detected during surgery,reduce the residue of cancer cells,and facilitate the prognosis of patients,with high clinical value.
