CT colonography
Brief summary
The aim of this study is to evaluate a low-dose of bowel preparation for Computed Tomography Colonography (CTC) versus free laxative CTC with regard to performance, feasibility, patient tolerability and acceptance.
Detailed description
Computed Tomography Colonography (CTC) is a valid alternative to colonoscopy in the detection of cancer, polyps and other colon lesions. High volume cathartic preparations, low volume cathartic solutions with oral tagging agent and tagging agent only are the procedures available for CTC. High volume preparations are a considerable burden for patients. Low volume cathartic solutions are more accepted by the patients, reduce the amount of tagging agent and the waiting time to the exam. Tagging agent only preparations represent a risk if they are taken without medical supervision.
Interventions
the day before the CTC: * low fiber diet * at 15.00: 2 tablets of bisacodyl (5 mg) * at 17.00: 1 litre of PEG-CS * liquid diet the day of the exam: * at home: 2 tablets of bisacodyl (5 mg) * at the Hospital (3 hours after tablets intake): 90 ml of Iopamidol in 500 ml of water * at the Hospital (5 minutes after Iopamidol intake): 10 mg of Metoclopramide mono chlorohydrate monohydrate im
the day before CTC: * low fiber diet * at 15.00: 90 ml of Iopamidol in 250 ml of water * at 17.00: 90 ml of Iopamidol in 250 ml of water * at 20.00: start liquid diet

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy | 20 min | Tagging. In prone and supine position, each colon segment (caecum, ascending, transverse, descending, sigma and rectum) will be graded by using a 4 point scale (from 0= greater than 75% of residuals to 3= minor than 25% of residuals). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy | 20 minutes | Residual fluid evaluation. In prone and supine position, each colon segment (caecum, ascending, transverse, descending, sigma and rectum) will be graded by using a 4 point scale (from 1= minor than 25% of the ap axis to 4= greater than 75% of the ap axis). |
| Safety | 2 days (the day before and the day of CTC) | Recording of all Adverse Events (AEs) occurring during the 2 days of treatment |
| Acceptability | 2 days (the day before and the day of the exam) | Evaluation of the patient discomfort related to bowel preparation. A 4 point scale is used: 1=none; 2=mild distress; 3=moderate distress; 4=severe distress. |
