Description
FuCheng Bian and three co-authors build a prediction chart for delayed bleeding after a colon tumor procedure, in a 2024 study. The procedure, endoscopic submucosal dissection, peels tumors off the bowel wall from inside. Bleeding that starts days later is its feared complication.
The team reviewed 587 patients treated over about two and a half years and split them into training and test sets. In training, delayed bleeding struck about nine percent. Three factors independently predicted it: a lesion in the rectum, a large lesion, and a long operation. The resulting nomogram, a visual scoring chart, discriminated well, with a C-index of 0.89, and its predictions matched actual outcomes closely on validation checks. The authors say estimating risk before surgery can target prevention and spare resources.
