高剂量率组织间近距离放射治疗（HDR-ISBT）广泛用于盆腔肿瘤的治疗。然而，有一些关于HDR-ISBT中施用器植入并发症的报道。我们描述了一个82岁的男性患者，在接受HDR-ISBT治疗的骨盆肿瘤复发后，植入施源器导致小肠穿孔的病例。最终，患者接受了剖腹手术和部分肠切除术。我们识别出施用器插入粘膜表面肿瘤部分的部位。病理检查证实肿瘤已直接浸润小肠，浸润部分已达粘膜下层，这是第一次发表的关于施放器植入引起小肠穿孔的报道。在怀疑肿瘤肠道浸润的情况下，应最大限度地谨慎进行HDR-ISBT。
High-dose-rate interstitial brachytherapy (HDR-ISBT) is widely used for the treatment of pelvic tumors. However, there are a few reports on complications of applicator implantation in HDR-ISBT. We describe a case of small bowel perforation caused by applicator implantation in an 82-year-old male patient with recurrence tumor in the pelvis treated with HDR-ISBT. Eventually, the patient underwent laparotomy and partial intestinal resection. We recognized the site where the applicator was inserted into a part of the tumor on the mucosal surface. Pathological examination confirmed that the tumor had infiltrated the small intestine directly and that the infiltrated part had reached the submucosa.This is the first published report about small bowel perforation caused by applicator implantation. In cases where intestinal infiltration of the tumor is suspected, HDR-ISBT should be performed with maximum caution.
