Abstract

Background/aim: Transanal total mesorectal excision is a useful technique while performing lower rectal cancer and deep pelvic surgery. However, it is a relatively difficult procedure, and unique complications such as urethral injury have been reported. Although there have been a few reports on urethral visualization, we investigated whether it is possible to visualize the urethra using a fluorescent urethral catheter.

Patients and methods: We retrospectively examined the background and short-term surgical outcomes in 17 patients who, between April 2022 and December 2023, underwent transanal total mesorectal excision and transperineal total mesorectal excision with fluorescent ureteral catheters in place due to high risk of urethral injury.

Results: The urethra was recognized in one out of 11 patients (9.1%) in laparoscopic abdominoperineal resection and all three patients (100%) in laparoscopic total pelvic extenteration. No urethral injury was observed.

Conclusion: Visualization of the urethra by inserting a fluorescent ureteral catheter may prevent urethral injury in patients undergoing transanal/transperineal total mesorectal excision who are at high risk of urethral injury.

经肛门/会阴全肠系膜切除术中近红外光观察尿道可视化。

背景/目的：经肛门全肠系膜切除是低位直肠癌和深盆腔手术的有效技术。然而，这是一个相对困难的过程，并且有独特的并发症，如尿道损伤的报道。虽然有一些关于尿道可视化的报道，但我们研究了使用荧光导尿管是否有可能可视化尿道。患者和方法：我们回顾性分析了17例患者的背景和短期手术结果，这些患者于2022年4月至2023年12月期间因尿道损伤的高风险而接受经肛门全肠系膜切除术和经会阴全肠系膜切除术，并放置荧光输尿管导管。结果：腹腔镜腹会阴切除术11例患者中有1例（9.1%）能识别出尿道，腹腔镜全盆腔伸展术3例患者均能识别出尿道（100%）。未见尿道损伤。结论：在尿道损伤高危患者行经肛门/经会阴全肠系膜切除术时，应用输尿管荧光导尿管观察尿道可预防尿道损伤。

期刊介绍： ANTICANCER RESEARCH is an independent international peer-reviewed journal devoted to the rapid publication of high quality original articles and reviews on all aspects of experimental and clinical oncology. Prompt evaluation of all submitted articles in confidence and rapid publication within 1-2 months of acceptance are guaranteed. ANTICANCER RESEARCH was established in 1981 and is published monthly (bimonthly until the end of 2008). Each annual volume contains twelve issues and index. Each issue may be divided into three parts (A: Reviews, B: Experimental studies, and C: Clinical and Epidemiological studies). Special issues, presenting the proceedings of meetings or groups of papers on topics of significant progress, will also be included in each volume. There is no limitation to the number of pages per issue.
