TME has become the "gold standard" treatment for rectal cancer Worldwide. [5] [6] The operation can be done by open surgery, laparoscopic or Robot-assisted. [7] For lower down tumours in the middle and lower third of the rectum a new procedure has been developed known as Transanal-Total Mesorectal Excision (TaTME). Instead of the dissection via ...
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.
William Ernest Miles (1869–1947), an English surgeon first performed the surgery of removing the rectum in 1907. He assumed that the rectal cancer can spread in both upwards and downward directions, thus necessitating the removal of the entire rectum together with the anal sphincters, resulting in a permanent stoma by connecting the proximal end of the descending colon to the skin.
A new treatment for locally advanced rectal cancer (LARC) reduced the existence of tumors by twice the amount as previous approaches, eliminating the need for surgery, a new study found.
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

Previously, anal cancer was treated with surgery, and in early-stage disease (i.e., localised cancer of the anus without metastasis to the inguinal lymph nodes), surgery is often curative. The difficulty with surgery has been the necessity of removing the internal and external anal sphincter, with concomitant fecal incontinence.
