Tubular adenomas of the sigmoid colon require treatment tailored to each condition. The main treatment options include endoscopic mucosal resection, endoscopic mucosal dissection and laparoscopy for localized intestinal resection. 1. Endoscopic mucosal resection: for relatively small and small lesions, the lesion can be completely dissected by endoscopic mucosal resection alone. 2. Endoscopic mucosal dissection: for relatively large lesions where simple mucosal resection is not effective, the lesion can be separated through endoscopy and then completely resected. 3. Laparoscopic local mesenteric resection: some suspected malignant tubular adenomas with relatively large reaction and wide base can be directly performed laparoscopic local mesenteric resection. After the operation of sigmoid tubular adenoma, routine pathological examination is needed to exclude malignancy; the recovery of the operation area and the status of defecation should also be observed. If there is obvious blood in the stool and abdominal pain, it is necessary to consult a doctor in time for observation and standardized treatment under the guidance of the clinician, so as not to be negligent to avoid delaying the condition.
