At Asan Medical Centre, Ileoanal Anastomosis (J-Pouch) Surgery is performed using specialized colorectal surgical techniques and comprehensive preoperative evaluation. Established in 1989, this ISO accredited hospital in Seoul, South Korea has 2700 beds and offers advanced colorectal surgery, gastroenterology, minimally invasive surgery, and stoma care services.

Ileoanal Anastomosis (J-Pouch) Surgery may be considered for selected patients with conditions such as ulcerative colitis or certain inherited colorectal disorders requiring removal of the colon and rectum. The procedure is often performed in stages, particularly when the patient's health or nutritional condition requires a temporary ileostomy. During surgery, the small intestine is formed into a pouch and connected to the anal canal to restore intestinal continuity.
