Precision prevention of colorectal neoplasia in patients undergoing hemorrhoid surgery: an explainable machine learning model for identifying the risk of precancerous neoplastic polyps (opens in new tab)

BackgroundHemorrhoids are common and frequently present with hematochezia. However, these symptoms can overlap with manifestations of precancerous neoplastic polyps (PNP) and early colorectal cancer. Although colonoscopy is recommended for patients with hematochezia, it is often not completed in routine practice for various reasons, which may lead to missed diagnoses in some patients. We built and validated a machine learning–based model to identify patients undergoing surgery for severe hemo...
