Which description matches a J-pouch procedure?

• A. Remains the colon and attaches the ileum to the rectum
• B. Removes the colon and attaches the ileum to the rectum
• C. Creates a urethral diversion
• D. Removes only the rectum

Answer: (B)

The main idea is that a J-pouch (ileal pouch-anal anastomosis) is created after removing the colon to restore the storage and continence function of the bowel. The ileum is reshaped into a J-shaped reservoir and then connected to the rectum/anal canal, so stool is stored in the ileal pouch rather than passing directly from the ileum to the outside. This procedure is used after proctocolectomy to avoid a permanent ileostomy and to maintain continence.

That’s why the description fits best: the colon is removed and the ileum is attached to the rectum, forming the reservoir that stores stool. The other options describe scenarios that don’t involve creating an ileal pouch connected to the rectum, such as preserving the colon, creating a urinary diversion, or removing only the rectum, which would not yield a J-pouch.
