Intraoperative identification of these nerves is particularly challenging following neoadjuvant chemoradiotherapy. This study evaluated the feasibility of indocyanine green (ICG)-guided fluorescence imaging for the selective visualisation of pelvic autonomic nerves during minimally invasive TME.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and Methods:<\/jats:title>\n                    <jats:p>In this prospective pilot feasibility study, 24 patients undergoing minimally invasive TME for rectal adenocarcinoma were included. Twelve patients underwent conventional nerve-preserving TME guided by anatomical landmarks, whereas twelve received intravenous ICG (0.5 mg\/kg) 12 h preoperatively. Near-infrared imaging was used intraoperatively. Short-term post-operative outcomes assessed included the day of urinary catheter removal, need for recatheterisation and incidence of urinary tract infection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The median age was 57 years, and baseline characteristics were comparable between groups. In the fluorescence-guided group, autonomic nerves appeared as distinct non-fluorescent structures against a fluorescent background. Earlier catheter removal was observed in the ICG group (predominantly post-operative day 2 vs. day 3). Recatheterisation was required in one patient in the fluorescence-guided group compared with three in the conventional group. One UTI occurred in the conventional group, whereas none were observed in the fluorescence-guided group. No adverse reactions to ICG were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Pre-operative low-dose ICG administration is feasible and safe for real-time intraoperative visualisation of pelvic autonomic nerves during minimally invasive TME and may improve early post-operative urinary outcomes.
