The end of the remaining sigmoid colon is brought out permanently as an opening, called a stoma , which is used by the patient in conjunction with a colostomy pouch, on ...
There are several surgical approaches to treat megacolon, such as a colectomy [2] [14] (removal of the entire colon) with ileorectal anastomosis (ligation of the remaining ileum and rectum segments), or a total proctocolectomy (removal of colon, sigmoid and rectum) followed by ileostomy or followed by ileoanal anastomosis.

Often, it is used in conjunction with chemotherapy in a neoadjuvant fashion to enable surgical resection, so that ultimately a colostomy is not required. However, it may not be possible in low lying tumors, in which case, a permanent ...
