Ostomy pouching system
（重定向自Colostomy pouch）
An ostomy pouching system or colostomy bag is a prosthetic medical device that provides a means for the collection of waste from a surgically diverted biological system (colon, ileum, bladder) and the creation of a stoma. Pouching systems are most commonly associated with colostomies, ileostomies, and urostomies.
