The Swedish Patient Registry provides data about diagnoses and surgical procedures for research purposes. There are, however, almost no validation studies of the data on surgical procedures, and none of oesophageal cancer surgery.
This was a validation study of the accuracy of codes representing oesophageal cancer resection, surgical approach and oesophageal substitute in the Swedish Patient Registry during the period 1987-2005. The registered data were compared with a thorough review of the corresponding operation charts collected from medical records.
Among 1358 patients with a code representing oesophageal resection in the Patient Registry, the positive predictive value was 99.6%. The dominant surgical procedures in terms of surgical approach (transthoracic) and type of oesophageal substitute (gastric conduit) had positive predictive values of 99.8% and 99.4%, respectively. The more rare procedures with regards to approach (transhiatal) and substitute (bowel) had lower positive predictive values of 68.8% and 68.5%, respectively.
The high accuracy of the data regarding oesophageal cancer resection in the Swedish Patient Registry stresses its appropriateness for research purposes.
瑞典患者注册中心提供了有关诊断和手术程序的数据，用于研究目的。然而，几乎没有关于手术程序数据的验证研究，也没有关于食管癌手术的验证研究。
这是一项关于瑞典患者注册中心在 1987 年至 2005 年期间的食管癌切除术、手术入路和食管替代物代码准确性的验证研究。将登记数据与从病历中收集的相应手术图表进行详细审查进行比较。
在患者注册中心中，有 1358 例代码代表食管切除术的患者中，阳性预测值为 99.6%。在手术入路（经胸）和食管替代物（胃管）方面，主要的手术方法的阳性预测值分别为 99.8%和 99.4%。在入路（经食管裂孔）和替代物（肠道）方面，较为罕见的手术方法的阳性预测值分别为 68.8%和 68.5%。
瑞典患者注册中心中食管癌切除术数据的高度准确性强调了其在研究中的适当性。
