| Variable | Non-surgical enema reduction (air or barium enema) | Surgery | Total intussusception cases | p-value | ||
|---|---|---|---|---|---|---|
| Total surgical cases | Surgery after enema failure | Primary surgery | ||||
| Total | 31,207 (90.0) | 3,481 (10.0) | 835 (2.4) | 2,646 (7.6) | 34,688 (100.0) | <0.001* |
| Boys | 20,104 (89.4) | 2,396 (10.6) | 566 (2.5) | 1,830 (8.1) | 22,500 (100.0) | <0.001† |
| Girls | 11,103 (91.1) | 1,085 (8.9) | 269 (2.2) | 816 (6.7) | 12,188 (100.0) | |
| Age (mo) | 19.6 (11.3–30.8) | 17.4 (8.6–35.0) | 18.2 (9–31.8) | 17.2 (8.6–36.5) | 19.4 (10.9–31.1) | <0.001‡ |
Values are presented as number (%) or median (interquartile range).
*The p-value between non-surgical enema reduction treatment and surgical treatment was calculated using the chi-square test. †The difference of non-surgical treatment and surgical treatment between boys and girls was calculated using the chi-square test. ‡The age difference (19.6 vs. 17.4 months) between the non-surgical enema reduction group and the surgical treatment group was calculated using the Mann-Whitney U-test.
