Abstract：
Aims: Computed tomography colonography (CTC) is seen as a more tolerable alternative to colonoscopy, but patients struggle with the steps required for optimal diagnostic imaging. This prospective study aims to understand the experience of patients undergoing CTC. Methods: A survey was completed by a convenience sample of patients before and after CTC over 7 months. The 13-item questionnaire covered pre-test information, overall and specific experience of the test. The responses were tabulated and analyzed using descriptive statistics. Qualitative free-text responses were coded for content and thematic analysis. Results: At a response rate of 51%, surveys were received from 41 patients. Overall, most patients (54%) found the investigation better than expected. However, 18% stated they were not informed of potential side effects. Side effects were experienced by 49% of patients, including diarrhea (34%) and abdominal pain (24%). About 59% experienced discomfort with gas insufflation, and 86% found turning during the investigation difficult. Conclusion: A significant proportion of patients undergoing CTC experience side effects and difficulties completing the investigation. Patient information is important to improve patient experience of CTC.
摘要：
目的：计算机断层扫描结肠成像（CTC）被视为结肠镜检查的更可耐受的替代方法，但是患者在最佳诊断成像所需的步骤上挣扎。这项前瞻性研究旨在了解接受CTC的患者的经历。方法：对CTC前后超过7个月的患者进行方便抽样调查。13项问卷涵盖了测试前的信息，测试的总体和具体经验。使用描述性统计对答复进行列表和分析。对定性自由文本响应进行了编码，以进行内容和主题分析。结果：在51%的应答率下，接受了41例患者的调查。总的来说,大多数患者（54％）发现调查比预期的要好。然而,18%的人表示他们没有被告知潜在的副作用。49％的患者经历了副作用，包括腹泻（34%）和腹痛（24%）。大约59%的人对气体吹入感到不适，86%的人在调查过程中发现转弯困难。结论：接受CTC的患者中有很大比例的副作用和难以完成调查。患者信息对于改善CTC的患者体验非常重要。
