Abstract:
Objective:To examine the safety and feasibility of using fusion indocyanine green fluorescence imaging (FIGFI) technique for intraoperative evaluation of colorectal perfusion in the totally laparoscopic left colectomy.Methods:A retrospective cohort study was conducted to collect the clinical data of 58 patients with left colon cancer who underwent totally laparoscopic surgery at the Colorectal Surgery Department, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to December 2019. There were 39 males and 19 females, aging (57.0±10.1)years(range:28 to 75 years). According to whether the FIGFI was used during the operation, they were divided into 36 cases in the study group and 22 cases in the control group. The clinical pathological characteristics, operative and postoperative recovery of the two groups were compared by t test, χ 2 test, and Fisher exact test. Results:All the 58 patients underwent R0 resection with totally laparoscopic surgery. In the study group, due to poor bowel blood flow after cutting the mesentery (Sherwinter score = 1), 1 patient had to be expanded the resection range until the blood flow was rich(Sherwinter score≥3), and 1 patient in the control group had the complication of postoperative anastomotic leakage of grade A. Compared with the control group, the operation time in the study group was shorter ((156.3±43.5) minutes vs. (180.4±41.3) minutes, t=-2.083, P=0.042). However, there were no significant differences in the amount of blood loss, postoperative hospital stay, postoperative time of anal exhaust, length of bowel resection, number of lymph nodes dissected, and in the incidence of postoperative complications between the two groups. Median follow-up period was 23 months (range: 18 to 37 months). There were no long-term postoperative complications such as ischemic enteritis and anastomotic stenosis in both groups. Conclusions:The FIGFI is safe and feasible to assess the blood supply of intestinal segment and anastomosis during totally laparoscopic left hemicolectomy, and is easy to operate. It is expected to reduce the incidence of anastomotic leakage.
