Intraoperative distinction of pituitary adenoma from normal gland is critical in maximizing tumor resection without compromising pituitary function. Contact endoscopy provides a noninvasive technique that allows for real-time in vivo visualization of differences in tissue vascularity. Two illustrative cases of endoscopic endonasal approaches (EEAs) for resection of pituitary adenoma illustrate the use of contact endoscopy in identifying tumor from gland and differentiating a thin section of normal gland draped over the underlying tumor, thereby allowing for safe extracapsular tumor resection. Contact endoscopy may be used as an adjunct for intraoperative, in vivo differentiation of pituitary gland and adenoma.

在不损害垂体功能的前提下，最大限度地切除垂体腺瘤，术中区分垂体腺瘤与正常腺体至关重要。接触式内镜提供了一种非侵入性技术，可实时在体内观察组织血管的差异。两例垂体腺瘤经鼻内镜切除术的典型病例说明了接触式内镜在识别肿瘤与腺体以及区分覆盖在肿瘤下方的正常腺体薄片方面的应用，从而实现安全的囊外肿瘤切除。接触式内镜可作为术中在体内区分垂体和腺瘤的辅助手段。视频可在此处查看：https://stream.cadmore.media/r10.3171/2021.10.FOCVID21199 。
