摘要

目的：术中锥形束计算机断层扫描（CT）可以为逆行放射插入式胃造口术（RIG）提供解剖学评价。本研究探讨了锥束ct辅助RIG的技术和辐射剂量影响，并将其与仅使用透视的传统RIG技术进行了比较。材料与方法我们分析了107例逆行RIG手术，其中48例使用锥束CT辅助，59例仅使用常规透视。结果48例锥形束ct辅助RIG手术中46例（95.8%）成功，59例常规RIG手术中47例（79.6%）成功。传统的RIG技术遇到了一个并发症（管移位）。锥束ct辅助RIG的平均剂量面积积（DAP）显著高于8.5 Gy。常规技术DAP为3.4 Gy.cm2。锥束ct辅助RIG的平均程序和透视筛查时间明显较低。结论锥形束ct辅助RIG是一种安全有效的技术。虽然患者的辐射剂量增加了，但明确的解剖评估、更高的成功率和减少介入人员透视筛查暴露的主要并发症的缺乏抵消了这一影响。

Cone beam computed tomography (CT)–assisted radiologically inserted gastrostomy. Technical considerations and impact on radiation dose

AIM

Intraprocedural cone beam computed tomography (CT) can provide anatomic evaluation during retrograde radiologically inserted gastrostomy (RIG). This study explores the technical and radiation dose implications of cone beam CT-assisted RIG, compared with conventional RIG technique using fluoroscopy alone.

MATERIALS AND METHODS

One hundred seven retrograde RIG procedures were included in the analysis, 48 of which were performed with cone beam CT assistance and 59 using conventional fluoroscopy alone.

RESULTS

Forty six of the 48 (95.8%) cone beam CT-assisted RIG procedures and 47 of the 59 (79.6%) procedures using conventional RIG technique were successful. One complication (tube malplacement) was encountered with the conventional RIG technique. Cone beam CT-assisted RIG was associated with significantly higher average dose area product (DAP) of 8.5 Gy.cm² compared with conventional technique’s DAP of 3.4 Gy.cm². The average procedure and fluoroscopic screening time for cone beam CT-assisted RIG was significantly lower.

CONCLUSION

Cone beam CT-assisted RIG is a safe and effective technique. Whilst there is an increase in radiation dose for the patient, it is counter balanced by definitive anatomical evaluation, higher success rates and lack of major complication with reduced fluoroscopic screening exposure for interventional staff.
