## **Core Concept**
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by diffuse inflammation of the colonic mucosa. Surgical intervention is considered in specific scenarios where medical management fails or in cases of complications. The primary surgical goal is to remove the diseased portion of the colon.

## **Why the Correct Answer is Right**
The correct approach involves understanding that surgical treatment for ulcerative colitis is not limited to late cases or emergency situations but is also considered when medical treatment fails. This includes:
- **Failed medical management:** When patients do not respond to or are dependent on corticosteroids.
- **Pouch surgery:** A procedure often performed for ulcerative colitis, especially when colectomy is indicated. It involves creating a pouch from the small intestine to serve as a reservoir for stool, aiming to preserve bowel continuity.
- **Restorative proctocolectomy:** This is a type of surgery where the entire colon is removed, and a pouch is created from the small intestine to store stool, which is then passed through the anus. It's a definitive surgical treatment but typically not an emergency procedure.

## **Why Each Wrong Option is Incorrect**
- **Option A:** "Done in late cases only" - This statement is too narrow. Surgical intervention can be considered at any stage if there's a compelling reason, such as failure of medical management or complications.
- **Option D:** "Restorative proctocolectomy done in emergency cases" - While emergency colectomy might be necessary in cases of toxic megacolon or severe hemorrhage, restorative proctocolectomy with pouch creation is usually performed in a staged manner and not as an emergency procedure.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that surgical intervention in ulcerative colitis is considered for:
- Failure of medical management
- Complications like toxic megacolon
- High-grade dysplasia or cancer
- Quality of life issues

## **Correct Answer:** B.
