Colonoscopy can check for colorectal disease around the umbilicus because it is able to examine the anus, the colorectum, and the end of the ileum, but it cannot determine whether tissues such as the small intestine, the skin and muscles around the navel, or other organs have disease.
The scope of colonoscopy is from the rectum to the ileocecum, which is the entire extent of the colon, and colonoscopy can examine diseases of the colorectum around the umbilicus. However, diseases of the small intestine around the umbilicus cannot be clearly diagnosed by colonoscopy. If no obvious abnormality is seen by colonoscopy, further CT imaging of the small intestine, capsule endoscopy, or small bowel examination can be done.
Colonoscopy also cannot examine the skin muscles or other organs around the navel. These organs and tissues can be examined by other screening methods such as abdominal ultrasound.
A colonoscopy includes checking for malignant tumors, mucosal lesions, and benign space-occupying lesions. If you suspect that you have a disease around the navel, it is recommended that you consult a doctor in time to improve the examination of the program, according to the final examination results of targeted treatment.
