Indocyanine green (ICG) real-time blood perfusion fluorescence angiography in laparoscopic radical resection of rectal cancer has great potential clinical value and can visually judge intestinal tract blood supply to improve the surgery safety, reduce postoperative complications, and ensure the recovery of patients after surgery. Objective: To explore the efficacy of the intraoperative use of indocyanine-green fluorescence angiography in laparoscopic rectal resections in patients with rectal cancer. Methods: In the present study, 109 rectal cancer patients were included and assigned to different surgical groups [ICG and control groups] for analysis. Statistical analysis was carried out for various common postoperative complications in the two groups. Finally, the patients in the ICG fluorescence imaging group had a timely adjustment of the proximal resection of the intestinal tube before the proximal bowel of the lesion was cut off when the intestinal blood supply was insufficiently assessed by fluorescence imaging. Two subgroups, the adjustment and the non-adjustment groups, were analyzed. Results: Compared with the control group, the postoperative anal ventilation time in the ICG group was shorter than that in the control group (P 0.05). In addition, the postoperative complications were lower than those in the control group, and the differences were statistically significant (P 0.05). However, the distance between the tumor from the anal verge in the adjustment group was smaller than that in the non-adjustment group, and the difference was statistically significant (P 0.01). Conclusion: Compared with conventional laparoscopic radical resection of rectal cancer, ICG real-time indocyanine green fluore- scence angiography was safe and feasible. This technique is a promising intraoperative tool for the assessment of bowel perfusion especially suitable for patients with lower rectal cancer.展开更多

Methods: The data of 78 patients who underwent laparoscopic radical resection of right-sided colon cancer between January 2018 and August 2019 were retrospectively analysed. The surgical method was selected by the patients. The patients were divided into two groups according to the surgeons’ positioning habits and trocar placements. The group with the lead surgeon standing between the patient’s legs had 35 patients, and the group with the lead surgeon standing at the left side of the patient had 43 patients. The operation time, intraoperative blood loss, postoperative anal gas evacuation time, postoperative urinary catheter indwelling time, postoperative hospital stay, C-reactive protein (CRP) level on the first day after surgery, and postoperative pathological data and complications were compared between the two groups. Results: All patients underwent the laparoscopic radical resection of right-sided colon cancer, none converting to laparotomy. No significant difference (P > 0.05) in intraoperative blood loss (57.6 ± 21.3 ml vs 60.2 ± 35.3 ml), postoperative anal gas evacuation time (3.5 ± 1.1 d vs 3.8 ± 1.3 d), postoperative urinary catheter indwelling time (2.6 ± 1.3 d vs 2.4 ± 1.2 d), postoperative hospital stay (7.1 ± 1.8 d vs 7.5 ± 2.1 d), or CRP level on the first day after surgery (54.7 ± 9.6 mg/L vs 53.9 ± 8.2 mg/L) was detected between the two groups. The operation time was shorter in the group with the lead surgeon standing between the patient’s legs (185.2 ± 25.6 min vs 196.2 ±19.7 min) (P < 0.05). The two groups did not differ significantly in the tumour length (4.2 ± 1.3 cm vs 3.9 ± 1.5 cm), number of dissected lymph nodes (27.5 ± 11.6 vs 25.1 ± 15.4), pathological type, or postoperative pathological tumour-node-metastasis stage (P > 0.05). No patients died or had anastomotic fistula during their postoperative hospital stay, and the incidence of postoperative complications did not differ between the two groups (22.9% (8/35) vs 23.3% (10/42);P > 0.05). Conclusion: Under the principle of radical resection, the surgeon should adopt the most suitable standing position and trocar placement according to the specific situation. If the surgeon stands between the patient’s legs, this might shorten the operation time and promote a smoother surgery.展开更多
