| Fluoroscopy-guided pneumatic enema reduction |
Air |
Higher success rate than liquid enema |
Exposure to ionizing radiation |
| Reach higher intracolonic bowel pressure |
Only demonstrate bowel lumen |
| Most widely used in current practice |
| Clearer, lower in radiation, faster, and less expensive, compared to liquid enema |
| Fluoroscopy-guided barium enema reduction |
Barium |
Easy to identify achievement of enema reduction |
Possibility of barium staining in peritoneal cavity in case of perforation |
| Exposure to ionizing radiation |
| Can be messy due to coming out of contrast from anus |
| Only demonstrate bowel lumen |
| Ultrasound-guided hydrostatic enema reduction |
Saline |
Lack of exposure to ionizing radiation |
Require an on-call operator being familiar with this technique |
| Direct real-time visualization of intussusception and monitoring reduction process |
Increased risk of spillage of fecal contents into peritoneal cavity in case of perforation |
| May detect pathologic lead point |
Questionable easiness of detecting cases complicated by perforation during reduction |
| Reported high success rate and low perforation rate similar to other methods by skilled operators |
Can be messy due to coming out of contrast from anus |
