INTRODUCTION
Percutaneous cryoablation is an emerging treatment option for the small renal mass. It poses a risk of thermal injury to adjacent tissues, limiting its application. We describe pneumodissection, a novel technique for preventing thermal injury during percutaneous cryoablation.
MATERIALS AND METHODS
The cases of 4 patients who underwent percutaneous renal cryoablation and pneumodissection were retrospectively reviewed.
RESULTS
Pneumodissection mechanically separated four tumors from overlying bowel segments (mean distance 1.2 ± 0.4 cm), permitting successful cryoablation. There were no complications or recurrences with 7.5 months of follow-up.
CONCLUSIONS
Pneumodissection is a feasible displacement technique that facilitates percutaneous cryoablation in at-risk patients. Further study is warranted.
引言
经皮冷冻消融术是治疗小肾肿瘤的一种新兴治疗方法。它存在对邻近组织造成热损伤的风险，限制了其应用。我们描述了一种气腔分离术，这是一种在经皮冷冻消融术中预防热损伤的新技术。
材料与方法
回顾性分析4例行经皮肾冷冻消融和气腔分离术患者的病例。
结果
气腔分离术通过机械方式将4个肿瘤与覆盖其上的肠段分离（平均距离1.2±0.4厘米），从而使冷冻消融术得以成功实施。随访7.5个月期间无并发症或复发情况。
结论
气腔分离术是一种可行的移位技术，有助于对有风险的患者实施经皮冷冻消融术。有必要进行进一步研究。
