Side-to-end coloanal anastomosis

Side-to-end coloanal anastomosis is a surgical procedure used in the treatment of rectal cancer. It involves the reconnection of the colon to the anus after the removal of the rectum. This procedure is often performed as part of a low anterior resection (LAR) or an abdominoperineal resection (APR).

Procedure

The procedure begins with the surgical removal of the rectum, which is affected by cancer. The colon is then reshaped into a pouch, known as a J-pouch, to act as a new rectum. The pouch is then connected to the anus, allowing for the normal passage of stool.

The side-to-end coloanal anastomosis procedure is often performed laparoscopically, which involves making small incisions in the abdomen and using a camera to guide the surgery. This minimally invasive approach can result in less postoperative pain, a shorter hospital stay, and a quicker return to normal activities.

Benefits

The main benefit of a side-to-end coloanal anastomosis is that it allows the patient to maintain normal bowel function after the removal of the rectum. This can significantly improve the patient's quality of life compared to other surgical options that may require a permanent colostomy.

Risks and Complications

As with any surgical procedure, side-to-end coloanal anastomosis carries some risks. These can include infection, bleeding, and damage to surrounding organs. There is also a risk of anastomotic leak, which is when the connection between the colon and the anus leaks, leading to infection.
