Failure-to-rescue rate | Mortality among patients with morbidity |
Causal complication | Complication that led to subsequent complication (e.g., anastomosis leakage and intraabdominal abscess) |
Index complication | Complications that had the most significant influence on the patient’s postoperative course |
