This technical note introduces a modified Syed-Neblett type perineal template for high-dose-rate interstitial brachytherapy of gynecologic malignancies. The template can easily be disassembled after the insertion of the central needles into the pelvis allowing the cystoscopic and rectoscopic control of the needle positions. Thus needles penetrating the bladder or the rectum are recognized and can be repositioned before reassembling the template. Elimination of hot irradiation zones in tumor-free bladder and rectum walls might lead to reduction of severe late complications without compromising the therapeutic efficacy.
本技术说明介绍了一种改良的Syed-Neblett型会阴模板，用于妇科恶性肿瘤的高剂量率组织间近距离放射治疗。在将中心针插入骨盆后，该模板可轻松拆卸，以便通过膀胱镜和直肠镜控制针的位置。这样，穿透膀胱或直肠的针就能被识别出来，并在重新组装模板之前重新定位。消除无肿瘤的膀胱和直肠壁中的热点照射区域可能会减少严重的晚期并发症，同时又不影响治疗效果。
