Glossary of Key Terms

Medical terms explained in plain language.

Surgery & Anatomy

• <strong>IPAA (Ileal Pouch-Anal Anastomosis)</strong> — The medical name for J-pouch surgery. The ileum (end of the small intestine) is shaped into a pouch and connected to the anus.
• <strong>J-Pouch</strong> — The internal reservoir made from your small intestine. Called “J-pouch” because of its J-shape.
• <strong>Ileostomy</strong> — A temporary opening in the abdomen where stool exits into an external bag. Used while the pouch heals.
• <strong>Takedown</strong> — The surgery to reverse the temporary ileostomy and activate the pouch.
• <strong>Stoma</strong> — The small, round opening on the abdomen where the intestine comes through during an ileostomy.
• <strong>Anastomosis</strong> — A surgical connection between two parts of the intestine.

Conditions

• <strong>Ulcerative Colitis (UC)</strong> — A type of inflammatory bowel disease (IBD) that causes inflammation and ulcers in the colon and rectum.
• <strong>FAP (Familial Adenomatous Polyposis)</strong> — A genetic condition causing hundreds of polyps in the colon that can become cancerous.
• <strong>Pouchitis</strong> — Inflammation of the J-pouch lining. The most common pouch complication, usually treated with antibiotics.
• <strong>Cuffitis</strong> — Inflammation of the small strip of rectal tissue left behind during surgery. Similar to a mild flare of colitis.
• <strong>Stricture</strong> — Narrowing at the connection point between the pouch and anus. May cause difficulty passing stool.

Tests & Treatments

• <strong>Pouchoscopy</strong> — An endoscopy (camera exam) specifically to look inside the J-pouch. Used to diagnose pouchitis and other issues.
• <strong>Biologics</strong> — Medications made from living cells that target specific parts of the immune system. Used for stubborn inflammation.
• <strong>Probiotics</strong> — Beneficial bacteria supplements. Specific formulations studied for pouchitis prevention may help — ask your gastroenterologist.
• <strong>Bowel Obstruction</strong> — A blockage that prevents stool from passing through the intestine. Can be caused by scar tissue or food.
