Conditions
Brief summary
Small bowel distension is mandatory for the assessment of the bowel wall in CT enterography, but some patients were sufferring inadequate small bowel distension. So, it is important to prescribe personalized regimen according to patient's personal characteristics.
Detailed description
CT enterography has become an important tool in the evaluation of small bowel diseases, especially in patients with inflammatory bowel diseases. Small bowel distension is mandatory for the assessment of the bowel wall. So, it is important to find clinical risk factors for inadequate small bowel distension and prescribe personalized regimen according to patient's personal characteristics to reduce patient acceptance.
Interventions
different volume of 2.5% mannitol based on BMI was used in active comparator group
1500ml of 2.5% mannitol was used in experimental group

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical risk factors for inadequate small bowel distention | 2 month | Number of clinical risk factors for inadequate small bowel distention |
| Adequate small bowel distention | 4 month | The assessment system includes four parts 1. Whether the contrast reached the caecum is evaluate and recorded as yes or no 2. The overall presence of inhomogeneous contrast is evaluated and recorded as yes or no 3. The maximum dimension of a single loop in each quadrant was recorded. 4. The scale of loops of small bowel distended are evaluated and recorded as 0%-25%,26%-50%,51%-75%,75%-100% |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Side effects | 4 month | Side effects in 2 groups The degree of nausea, emesis, diarrhea, abdominal distension and cramp following ingestion are scored on a scale ranging from 0 to 4, in which a higher score represents a higher level of these targets. |
