| [ Summary ] |
In familial adenomatous polyposis (FAP) patients, apart from colorectal lesions, lesions outside the colon, such as desmoid tumors in the stomach, duodenum (papilla, non-papilla), and small intestine are also important. After being diagnosed with FAP, a patient should undergo not only colonoscopy but also upper gastrointestinal endoscopy, abdominal computed tomography examination, and ultrasound examination of the abdomen and neck. The Spigelman classification and Church classification are beneficial for the surveillance of non-papillary duodenal tumors and desmoid tumors, respectively. Multidisciplinary clinical decision and treatment are important for surveillance in FAP patients. |
