Nomogram effectively predicts anastomotic leakage in elderly patients.

A LASSO-based nomogram has been developed to predict anastomotic leakage (AL) in elderly patients undergoing laparoscopic gastrectomy. An analysis of 884 patients identified significant predictors, including age, ASA score, diabetes, intraoperative blood loss, and prognostic nutritional index. The nomogram demonstrated high predictive accuracy, achieving AUC values of 0.870 and 0.890 in training and validation cohorts, respectively. This tool allows for early identification of AL risk, potentially guiding preventive measures in surgical practice.
