| Site of intestinal perforation | Subgroup | Patients (No.) | Subcategory proportion (%) | Overall proportion (%) |
|---|---|---|---|---|

| Duo | 8 | 18.2 | 13.8 | |
| Jej | 11 | 25.0 | 19.0 | |
| Ile | 20 | 45.4 | 34.5 | |
| Unknown | 5 | 11.4 | 8.6 | |
| LI | 14 | 24.1 | ||
| Cec | 3 | 21.4 | 5.2 | |
| CO (AC) | 1 | 7.1 | 1.7 | |

Subcategory proportion refers to the proportion of a specific subgroup within its immediate superior category. Overall proportion refers to the proportion of perforation in a specific intestinal segment in the overall intestinal perforations. SI, small intestine; Duo, duodenum; Jej, jejunum; Ile, ileum; LI, large intestine; App., appendix; Cec, cecum; CO, colon; AC, ascending colon; TC, transverse colon; SC, sigmoid colon.
