A prosthesis was designed to protect the intestinal loop from external beam radiation therapy when post-operative radiation is indicated. It is a silicone inflatable balloon, which, when implanted displaces the intestinal loops out of the pelvic irradiation field. The prosthesis can be deflated between each course of irradiation, without surgery. The device has been used in 8 patients: 6 patients with recurrent pelvic tumor (2 rectal cancers, 1 anal cancer, 1 cancer of the endometrium, 1 cervical carcinoma, 1 ovarian carcinoma), 2 patients with primary tumor (1 malignant paraganglioma, 1 cervical carcinoma). Radiotherapy was administered by means of high power appliances. After radiotherapy, the prosthesis was deflated, then removed through a 3 cm incision under local or peridural anesthesia. The tolerance of the small intestine to the radiation therapy has been satisfactory in each case with no bowel injury due to radiation. Therefore, this simple device might be useful to prevent bowel injury during postoperative radiation in the treatment of abdominal and retroperitoneal tumor masses.
设计了一种假体，用于在术后需要进行外照射放疗时保护肠袢。它是一个硅树脂可充气气球，植入后可将肠袢移出盆腔照射野。该假体在每个放疗疗程之间可以放气，无需手术。该装置已用于8例患者：6例盆腔肿瘤复发患者（2例直肠癌、1例肛管癌、1例子宫内膜癌、1例宫颈癌、1例卵巢癌），2例原发性肿瘤患者（1例恶性副神经节瘤、1例宫颈癌）。放疗通过高功率设备进行。放疗后，将假体放气，然后在局部或硬膜外麻醉下通过3厘米的切口取出。在每种情况下，小肠对放疗的耐受性都令人满意，没有因放疗导致的肠损伤。因此，这种简单的装置可能有助于在腹部和腹膜后肿瘤肿块治疗的术后放疗期间预防肠损伤。
