Ileoanal anastomosis surgery (also known as J-pocket surgery, Ileostomy or colorectal surgery) naturally removes waste after removing the entire large intestine (colon and rectum).
J-sinus surgery is also known as anal ileoanal pouch anastomosis (IPAA). They aim to avoid the need for a permanent opening in the abdomen (stoma) for the passage of stool.
An ostomy may be performed in certain cases of:
- Small intestine cancer
- Colorectal cancer
- In other cases of cancer when they have invaded the colon or rectum (this may, for example, be the case with ovarian cancer)
- Inflammation of the stoma site
- Death of the tissue surrounding the stoma
- Laceration of the stoma
- Shrinkage of the skin around the stoma
- The ileostomy surgery takes about two hours under general anesthesia
- After 3 months
