**Question:** An infected pancreatic necrosis is treated with

A. antibiotics
B. necrosectomy
C. drainage alone
D. supportive care only

**Correct Answer:** B. necrosectomy

**Core Concept:**
An infected pancreatic necrosis is a life-threatening complication of acute pancreatitis, characterized by inflammation and necrosis of pancreatic tissue. Treatment options depend on the extent and severity of necrosis, as well as the presence of infection.

**Why the Correct Answer is Right:**
Necrosectomy is the surgical intervention that involves the removal of necrotic tissue (dead tissue) from the pancreas. In the context of an infected pancreatic necrosis, necrosectomy helps to eliminate the source of infection, reduce ongoing inflammation, and prevent further complications. Antibiotics are essential as part of the treatment plan, but they alone are not sufficient to address the necrotic tissue and infection.

**Why Each Wrong Option is Incorrect:**

A. Antibiotics (Option A): While antibiotics are crucial in treating the infection, they cannot address the necrotic tissue itself. Necrosectomy remains essential to remove the source of infection and prevent further complications.

B. Drainage alone (Option C): Drainage may help relieve pressure and drain infected fluid, but it does not remove the necrotic tissue and the infection source. This option is insufficient for treating infected pancreatic necrosis.

D. Supportive care only (Option D): Supportive care is essential in the management of acute pancreatitis and its complications. However, removing the necrotic tissue and addressing the infection source are crucial components of treatment that supportive care alone cannot provide.

**Clinical Pearl:**
Infected pancreatic necrosis is a severe complication of acute pancreatitis, often requiring a combination of surgical intervention (necrosectomy) and antibiotics for optimal treatment outcomes. Aggressive management and a multidisciplinary approach are essential in managing this life-threatening condition.
