We describe a training programme designed to instruct radiographers how to perform the double contrast barium enema (DCBE). The programme was assessed by comparing the first 50 unsupervised examinations with studies performed by senior registrars in radiology. Comparison was made by marking each study blind in terms of barium coating, colonic distension and visualisation of the colon in double contrast. A note was also made of the number of exposures, screening time, examination time and complications. No difference was found in any of these parameters when comparing the two groups. A further 50 patients were assessed at one year and this showed that standards had been maintained in terms of the above criteria. Follow-up at 3 years in the initial group has shown no missed pathology. We believe that delegation of the performance of the DCBE to radiographers is both acceptable to the patient and safe.
我们描述了一个旨在指导放射技师如何进行双重对比钡灌肠（DCBE）的培训项目。通过将前50例无监督检查与放射科高级住院医师进行的检查进行比较，对该项目进行了评估。通过对每项检查在钡剂涂布、结肠扩张和双重对比下结肠显影方面进行盲法评分来进行比较。还记录了曝光次数、透视时间、检查时间和并发症。比较两组时，在任何这些参数上均未发现差异。一年后对另外50例患者进行了评估，结果表明上述标准得到了维持。对初始组3年的随访显示没有漏诊病变。我们认为将DCBE的操作委托给放射技师对患者来说是可接受的且是安全的。
