BACKGROUND
The aim of this study was to determine intra- and interobserver reliability in 3D intrastomal ultrasound imaging of parastomal hernia and protrusion.
METHOD
A total of 40 patients were investigated. Two or three physicians evaluated the images twice, 1 month apart.
RESULTS
Inter-observer agreement was 72 % with a kappa value 0.59. For the last 10 patients there was an agreement of 80 % with a kappa value of 0.70. Intraobserver agreement was 80 % for one observer and 95 % for the other. The learning curve levelled out at around 30 patients.
CONCLUSION
Considering the learning curve of 30 patients, 3D intrastomal ultrasound is a reliable investigation method. 3D intrastomal ultrasonography has the potential to be the investigation of choice to differentiate between a bulge, a hernia, or a protrusion.
背景
本研究旨在确定 3D 经皮穿刺腔内超声成像在造口旁疝和突出物中的观察者内和观察者间的可靠性。
方法
共对 40 名患者进行了研究。两位或三位医生分别在 1 个月后两次评估图像。
结果
观察者间的一致性为 72%，kappa 值为 0.59。对于最后 10 名患者，一致性为 80%，kappa 值为 0.70。一位观察者的观察者内一致性为 80%，另一位为 95%。学习曲线在大约 30 名患者处趋于平稳。
结论
考虑到 30 名患者的学习曲线，3D 经皮穿刺腔内超声是一种可靠的检查方法。3D 经皮穿刺腔内超声成像有可能成为区分隆起、疝或突出物的首选检查方法。
