CatBoost helps physicians predict and prevent post-pancreatectomy acute pancreatitis, with strong accuracy metrics, highlighting its clinical value and the broader potential of machine learning in surgery.
A pioneering machine learning model has been developed to predict post pancreatectomy acute pancreatitis (PPAP) following the Whipple procedure, also called pancreaticoduodenectomy (PD), revolutionizing surgical precision and patient care, a study published in the “World Journal of Gastroenterology” journal expounded.
The Challenge at Hand: While the International Study Group of Pancreatic Surgery has defined and graded PPAP, no machine learning models have been designed to predict this potentially dangerous complication after PD—until now. This new predictive model intended to fill that gap, offering a proactive approach to identifying patients at risk.
The Approach that Followed: The research team analyzed clinical data from 381 patients who underwent PD between the year–2016 and 2024. The team analyzed PPAP risk factors and tested various machine learning algorithms—including logistic regression, random forest, CatBoost, etc., using recursive feature elimination to identify key variables for the most accurate predictive model.
The Outcomes: Among the patients, 88 (23.09%) developed PPAP, with these patients also showing a higher rate of postoperative pancreatic fistulas (55.68% vs 14.68%, P < 0.001) and grade C fistulas (9.09% vs 1.37%, P = 0.001). The CatBoost algorithm (gradient boosting algorithm) surpassed all others, earning an exceptional area under the receiver operating characteristic (ROC) curve of 0.859 in the training group and 0.822 in the testing group.
Key predictive variables included pancreatic texture, primary pancreatic duct diameter, BMI, calculated blood loss, and duration of surgery. The final CatBoost model, which incorporated these variables, revealed robust predictive power with ROC curves of 0.837 and 0.812 in the training and testing groups, respectively.
This AI-driven predictive model represents a major step forward in post-surgical care for pancreatic surgery.
