J-pouch coloanal anastomosis
J-pouch coloanal anastomosis is a surgical procedure that is performed to restore bowel continuity after the removal of the entire colon and rectum. The procedure involves the creation of a pouch from the end of the small intestine, which is then connected to the anus. This allows the patient to have normal bowel movements, despite the absence of the colon and rectum.
Procedure[edit | edit source]
The J-pouch coloanal anastomosis procedure is typically performed in two stages. The first stage involves the removal of the entire colon and rectum, a procedure known as a total proctocolectomy. The end of the small intestine, known as the ileum, is then shaped into a pouch, which is commonly referred to as a J-pouch due to its shape. The J-pouch is then connected to the anus, allowing for the passage of stool.
In the second stage of the procedure, the J-pouch is allowed to heal and adapt to its new role. This is typically achieved through a temporary ileostomy, which diverts the flow of stool away from the J-pouch and out of the body through a small opening in the abdomen. Once the J-pouch has healed, the ileostomy is reversed, and the patient is able to have normal bowel movements.
Indications[edit | edit source]
The J-pouch coloanal anastomosis procedure is typically indicated for patients with ulcerative colitis or familial adenomatous polyposis who require the removal of their entire colon and rectum. The procedure may also be performed in patients with certain types of colorectal cancer.
Risks and complications[edit | edit source]
As with any surgical procedure, the J-pouch coloanal anastomosis procedure carries risks and potential complications. These may include infection, bleeding, and complications related to anesthesia. Specific to the procedure, complications may include pouchitis, an inflammation of the J-pouch, and sexual dysfunction due to nerve damage during surgery.
