摘要

背景:在腹腔镜结直肠手术中,肿瘤的准确定位对于确保足够的消融边缘至关重要。因此,我们开发了一种新方法,即近红外腹腔镜结合术中结肠镜,从肠外观察盲肠肿瘤的轮廓。该方法是在使用硅胶管的模型上验证后使用的:患者是一名 77 岁的男性,其盲肠肿瘤靠近阑尾口。使用腹腔镜钳夹回肠末端,然后将结肠镜通过肛门插入盲肠。正常光线模式下的腹腔镜无法识别盲肠肿瘤。然而,近红外线模式的腹腔镜可以从肠道外清楚地看到盲肠肿瘤的轮廓,并可以用订书机安全地切除肿瘤。切除标本的组织病理学诊断为腺癌,浸润深度为 M,阴性边缘清晰:这是首次报道从肠外通过腹腔镜检测盲肠肿瘤的轮廓。这项技术对腹腔镜结直肠手术中的肿瘤轮廓检测既实用又安全,可用于各种内镜和腹腔镜联合手术。

Visualization of cecal tumor by near-infrared laparoscopy and intraoperative colonoscopy.

Background: In laparoscopic colorectal surgery, accurate localization of a tumor is essential for ensuring an adequate ablative margin. Therefore, a new method, near-infrared laparoscopy combined with intraoperative colonoscopy, was developed for visualizing the contour of a cecal tumor from outside of the bowel. The method was used after it was verified on a model that employed a silicone tube.

Case presentation: The patient was a 77-year-old man with a cecal tumor near the appendiceal orifice. Laparoscopy was used to clamp of the terminal ileum, and a colonoscope was then inserted through the anus to the cecum. The laparoscope in the normal light mode could not be used to identify the cecal tumor. However, a laparoscope in the near-infrared ray mode could clearly visualize the contour of the cecal tumor from outside of the bowel, and the tumor could be safely resected by a stapler. The histopathological diagnosis of the resected specimen was adenocarcinoma with an invasion depth of M and a clear negative margin.

Conclusions: This is the first report of the laparoscopic detection of the contour of a cecal tumor from outside the bowel. This technique is useful and safe for contouring tumors in laparoscopic colorectal surgery and can be used in various surgeries that combine endoscopy and laparoscopy.
