Endoscopic hemoclipping has been shown to be effective in the treatment of gastrointestinal bleeding. Here we describe a novel clinical application for endoscopic application of metal clips.
A middle-aged man with inoperable squamous cell cancer of the esophagus underwent per protocol a barium esophagogram to document tumor margins prior to radiation therapy. This study failed to localize the full extent of the tumor. At endoscopy, the tumor margins were clearly visible. To delineate the proximal and distal margins, detachable metallic clips were passed through the accessory channel of a standard endoscope and using a clip fixing device the clips were placed at each level. Subsequently, a chest x-ray was obtained.
Placement of mucosal clips facilitated radiotherapy.
Endoscopic mucosal clipping may serve as a useful technique for localizing or marking gastrointestinal lesions, especially for demarcating a precise radiation field when conventional techniques fail.
内镜下止血夹已被证明在治疗胃肠道出血方面有效。在此，我们描述一种内镜应用金属夹的新临床应用。
一名患有无法手术切除的食管鳞状细胞癌的中年男性按照方案在放疗前接受了食管钡餐造影以记录肿瘤边界。该研究未能确定肿瘤的全部范围。在内镜检查时，肿瘤边界清晰可见。为了确定近端和远端边界，将可拆卸金属夹通过标准内镜的附件通道，使用夹固定装置在每个层面放置夹子。随后，进行了胸部X光检查。
黏膜夹的放置有助于放疗。
内镜黏膜夹闭术可能是定位或标记胃肠道病变的有用技术，特别是在传统技术失败时用于划定精确的放疗区域。
