Which option correctly describes a J-pouch?

• 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)

A J-pouch is an ileal reservoir created from the end of the ileum and connected to the rectum (or anal canal) after removal of the colon to restore storage and continence. This procedure, often part of an ileal pouch-anal anastomosis, uses the ileum folded into a J-shape to hold stool so it can be evacuated through the anus, avoiding a permanent ostomy. Therefore, removing the colon and attaching the ileum to the rectum describes how the J-pouch functions. The other options don’t reflect creating a reservoir from the ileum to replace the colon/rectum’s storage function, nor do they describe an ileal pouch-anal setup.
