Core Tip

Core Tip: The prospective observational study evaluated the accuracy of the pancreatic computed tomography indices in predicting clinically relevant pancreatic fistula after pancreaticoduodenectomy. Though the predictive accuracy of pancreatic attenuation index (PAI) was low, pancreatic enhancement ratio (PER) exhibited good accuracy in predicting the development of clinically relevant postoperative pancreatic fistula (CR-POPF). Also, PER showed a statistically significant weak negative correlation with PAI and moderately positive correlation with fibrosis scores suggesting that PER may be an objective preoperative surrogate for assessing pancreatic texture. Preoperative quantification of PER can improve the risk stratification and management of patients at high risk of CR-POPF.
