Table 5.
Intensity of pain experienced by 198 patients during RWC-TVS and DCBE as assessed on a 10 cm VAS
| Intensity of pain | RWC-TVS | DCBE | p value |
| Overall intensity of pain (mean±SD) | 3.9±1.8 | 4.9±2.3 | <0.001 |
| Categorical intensity of pain (n (%)) | <0.001 | ||
| Mild pain (VAS score<2) | 30 (15.2) | 9 (4.5) | |
| Moderate pain (VAS score≥2 and≤5) | 119 (60.1) | 80 (40.4) | |
| Severe pain (VAS score>5) | 49 (24.7) | 109 (55.1) |
The Mann-Whitney test was used to compare the intensity of pain. The χ2 test was used to compare the type of pain.
DCBE, double-contrast barium enema; RWC-TVS, rectal water contrast transvaginal ultrasonography; VAS, visual analogue scale.
