许多研究者已经报道了灌注对结直肠吻合口愈合的影响，以及缺血在吻合口裂开中的作用，但事实证明，确定一种可以实时评估灌注并从而指导术中管理的方式是难以捉摸的。本研究描述了我们使用经肛门近红外 (NIR) 成像评估结直肠吻合术后吻合口灌注的初步经验。本研究纳入了接受结肠切除术且吻合口距离肛缘 25 厘米以内的患者。使用经肛门近红外系统来评估吻合水平的粘膜灌注。在直视下很容易导航直肠，并且吻合钉线可见。所有受试者均获得了高质量的近红外粘膜血管造影，证实经肛门近红外血管造影是可行且易于实施的。尽管近红外粘膜血管造影是一种有前途的方法，但仍需要进一步研究将该技术与临床结果相关联。
The influence of perfusion on colorectal anastomotic healing and, conversely, the role of ischemia in anastomotic dehiscence have been reported by many investigators, and yet identifying a modality that can evaluate perfusion in real time and thus guide intraoperative management has proven elusive. This study describes our initial experience using transanal near-infrared (NIR) imaging to evaluate anastomotic perfusion after colorectal anastomoses. Patients undergoing colectomy with an anastomosis within 25cm of the anal verge were included in this study. A transanal NIR system was used to assess mucosal perfusion at the level of the anastomoses. The rectum was easily navigated under direct vision and the anastomotic staple line visualized. High-quality NIR mucosal angiography was obtained in all subjects, confirming that transanal NIR angiography is feasible and simple to perform. Although NIR mucosal angiography is a promising modality, further study is needed to correlate this technique to the clinical outcome.
