Abstract

In this technical report, patient with total pharyngolaryngectomy and jejunum interposition experienced lymph node metastasis in the reconstructed mesenteric lymph nodes. Because this patient received 45 Gy of whole neck radiation therapy 24 years ago and small bowel's tolerance dose of the reconstructed jejunum was considered to be low, spacer gel injection was applied during image-guided interstitial brachytherapy to decrease doses to the reconstructed jejunum and previously irradiated carotid artery.

摘要

在本技术报告中，行全喉咽切除术并空肠代食管术的患者在重建的肠系膜淋巴结发生了转移。由于该患者24年前接受了45 Gy的全颈部放射治疗，且重建空肠的小肠耐受剂量被认为较低，因此在图像引导下组织间近距离放射治疗期间应用了间隔凝胶注射，以减少对重建空肠和先前接受过照射的颈动脉的剂量。
