Objective To investigate the application value of indocyanine green fluorescent laparoscopic technique in rectal cancer surgery.Methods A prospective study was conducted on 80 patients with rectal cancer who underwent concurrent surgical treatment at Kaifeng 155 Hospital from March 2021 to November 2023.According to whether indocyanine green fluorescence laparoscopy was applied,the enrolled patients were randomly divided into the study group(indocyanine green fluorescence laparoscopy,40 cases)and the control group(traditional laparoscopy,40 cases).The clinical features,operative and postoperative data of the two groups were compared and analyzed.Results There was no statistically significant difference between the study group and the control group in terms of gender,body mass index(BMI),smoking history,history of underlying diseases,ASA grading,tumor T staging,postoperative pathological staging,and distance from the tumor to the anal margin(P＞0.05).The intraoperative blood loss in the study group was(80.68±18.46)ml,which was less than(94.65±17.68)ml in the control group with significant difference(P=0.001).Indocyanine green fluorescence indicated poor blood flow and unsatisfactory anastomosis in the study group,4 cases were reconstructed during the operation,and no anastomosis was reconstructed during the operation in the control group,the difference between the two groups was statistically significant(P=0.034).There was no significant difference in operation time between the two groups(P＞0.05).The number of lymph nodes in the study group was higher than that in the control group(18.43±3.59 vs.14.02±3.10,P＜0.001),but there was no significant difference in the number of positive lymph nodes between the two groups(P＞0.05).There were no significant differences in the first time of getting out of bed,the first time of exhaust gas,the first time of eating and the time of hospitalization between the two groups(P＞0.05).There was no significant difference in the total incidence of postoperative complications between the two groups(P＞0.05),but the incidence of anastomotic fistula in the control group was significantly higher than that in the study group,with statistical significance(P=0.034).Conclusion The application of indocyanine green fluorescence laparoscopic technique in rectal cancer surgery can improve the accuracy of lymph node dissection,evaluate the satisfaction of anastomosis in real time,and reduce the incidence of anastomotic fistula.
