Li Chujun from the Digestive Endoscopy Center of the Sixth Affiliated Hospital of Sun Yat-sen University analyzed the data provided and found that the diagnosis was consistent with ulcerative colitis (it would be more reliable if terminal ileal lesions could be excluded), which was a total colon type. After the disease relapses, polypoid hyperplasia has already occurred and is still in the active stage. It is a chronic persistent type or a chronic relapsing type. The limited information provided makes it impossible to assess the severity of the disease. From a purely endoscopic perspective, it is a relatively serious situation. If you need standardized and active treatment, please go to the gastroenterology department of a nearby large hospital for further diagnosis and treatment. Generally speaking, if the treatment effect is satisfactory, it needs to be continued for more than 2 years. For those who are ineffective in standard medical treatment, surgical treatment—total large bowel resection—can be considered. As for the so-called lesions you mentioned, do you mean cancer? Long-term, recurring ulcerative colitis may lead to cancer in some cases. Judgment of the severity of the condition: Mild: diarrhea lt; 4 times/day, light or no blood in the stool, no fever and pulse rate, no or light anemia, and normal erythrocyte sedimentation rate. Moderate: Between mild and severe. Severe: frequent diarrhea with obvious mucus, pus and bloody stools, systemic symptoms such as fever and pulse rate, anemia, and accelerated erythrocyte sedimentation rate.
