Intraoperative indocyanine green near-infrared fluorescence guidance is an emerging optical imaging technology to facilitate better understanding of surgical landmarks. Herein, this technique was applied during the surgery for urachal carcinoma. A 50-year-old man with urachal carcinoma underwent laparoscopic partial cystectomy and pelvic lymph node dissection (PLND). Before the laparoscopic surgery, indocyanine green was injected cystoscopically around the tumor at the submucosa level. The tumor location and lymph drainage were clearly viewed. The lymphatic flow was along the superior vesical artery and the umbilical ligament. The obturator and external lymph nodes were not fluoresced. Template PLND was performed. Partial cystectomy was completed with cystoscopic monitoring of the margin and with endoscopic stapler to avoid tumor spillage. Intraoperative indocyanine green fluorescence views lymph drainage and tumor location and is useful to improve the quality of PLND and partial cystectomy.
术中吲哚菁绿近红外荧光引导是一种新兴的光学成像技术，有助于更好地识别手术标志。在此，该技术应用于脐尿管癌手术。一名50岁脐尿管癌男性患者接受了腹腔镜部分膀胱切除术和盆腔淋巴结清扫术（PLND）。在腹腔镜手术前，通过膀胱镜在肿瘤黏膜下层周围注射吲哚菁绿。肿瘤位置和淋巴引流清晰可见。淋巴液沿膀胱上动脉和脐韧带流动。闭孔淋巴结和腹股沟淋巴结未显荧光。进行了标准的PLND。在膀胱镜监测切缘的情况下，使用内镜吻合器完成部分膀胱切除术，以避免肿瘤播散。术中吲哚菁绿荧光可观察淋巴引流和肿瘤位置，有助于提高PLND和部分膀胱切除术的质量。
