If you find 2.5cm intestinal polyps, you should consult a doctor in time, follow the doctor’s instructions for colonoscopy, and carry out the corresponding surgical treatment after clarifying the location and nature of intestinal polyps. 1. Colonoscopy: colonoscopy and biopsy pathology can assess whether the polyp has undergone malignant changes, clarify the location and nature of intestinal polyps, and is the most meaningful means of examination to confirm the diagnosis of intestinal polyps. 2.Surgical treatment (1) Tip polyps: high-frequency electrocoagulation resection under enteroscopy or loop tip resection is used. (2) Wide base polyps: laparoscopic or open bowel resection. (3) Cancerous polyps: if the postoperative pathology shows that the polyp has become cancerous, radical surgery should be considered, and at the same time, the regional lymph nodes should be cleared and other comprehensive programs of treatment. In conclusion, 2.5cm intestinal polyps have a higher possibility of malignant transformation, and should be consulted in regular hospitals in a timely manner, so as to avoid delaying the condition.
