Rectal mass removal is relatively simple, but it is important to note that you need to take good care of the aftercare. Rectal mass removal involves removing the mass for pathologic examination through endoscopic anal surgery or transanal mass removal. There is usually no large traumatic opening. The steps of rectal mass excision are: good imaging before surgery, anesthesia during surgery, then local sectioning, and finally finding the mass for excision. After surgery, patients should pay attention to adjusting their diet, such as: consume less high-fat food, because high-fat diet will increase the secretion of bile acid, which has potential irritation and damage to the intestinal mucosa, and may induce the production of tumor cells; drink more skimmed milk; eat more vitamin-rich vegetables, such as leeks, celery, radish, etc., which can promote intestinal peristalsis, so as to promote bowel movement and make promote the smooth bowel movement. In addition, postoperative patients should also be appropriate physical exercise to improve their immunity.
