|---|---|---|---|---|---|---|---|---|---|
| 1a | 1b | 2 | 3 | 4 | 5 | 6 | 7 | 8 | |

CDC = Clavien–Dindo classification of 30-day morbidity; CDC 1 = normal course; CDC 2 = need of medication, parenteral feeding, or transfusion therapy; CDC 3 = need of further interventions; CDC 4 = need of therapy on ICU with single or multiorgan failure; CDC 5 = dead 30 days after diagnosis. Categories of small bowel perforations: 1a = directly diagnosed and treated iatrogenic perforation; 1b = iatrogenic perforation with delayed diagnosis and treatment; 2 = ischemic perforation; 3 = malignant perforation; 4 = inflammatory perforation; 5 = diverticula-associated perforation; 6 = traumatic perforation; 7 = foreign-body-associated perforation; 8 = unknown cause of perforation.
