## 문제

A nurse is assessing a patient with suspected acute pancreatitis. Which assessment finding would be most indicative of severe acute pancreatitis requiring immediate intervention?

A 45-year-old patient presents to the emergency department with severe epigastric pain radiating to the back, nausea, and vomiting that started 6 hours ago after consuming a large, fatty meal.

## 보기

1. Serum amylase level of 400 U/L (normal: 30-110 U/L)
2. Grey Turner's sign and abdominal stiffness **✔ 정답**
3. Temperature of 101.2°F (38.4°C) with mild tachycardia
4. Serum lipase level of 500 U/L (normal: 10-140 U/L)

**정답: 2**

## 해설

Grey Turner's sign indicates retroperitoneal hemorrhage from severe acute pancreatitis, requiring immediate intervention. Elevated enzyme levels confirm pancreatitis but not severity, while fever and tachycardia are less specific.

Clinical Context

This patient presents with classic symptoms of acute pancreatitis: severe epigastric pain radiating to the back, nausea, and vomiting following a fatty meal. While laboratory values and vital sign changes are important, the question asks for the finding most indicative of severe acute pancreatitis requiring immediate intervention. This distinction is critical because it separates uncomplicated pancreatitis from a life-threatening, necrotizing process.

Analysis of the Correct Answer

Grey Turner's sign (ecchymosis of the flanks) and abdominal stiffness (suggesting peritoneal irritation or retroperitoneal hemorrhage) are clinical manifestations of severe intra-abdominal pathology. In the context of pancreatitis, Grey Turner's sign is a classic indicator of severe acute necrotizing pancreatitis with retroperitoneal hemorrhage [1][2]. The presence of this sign signals a high mortality risk and the need for urgent, aggressive management, including fluid resuscitation, pain control, and potentially ICU admission [2][3]. Abdominal stiffness further supports the presence of significant peritoneal inflammation or hemorrhage, distinguishing this from simple pain-related guarding.

Analysis of Incorrect Options

- Option 1 & 4 (Elevated Amylase and Lipase): While a serum amylase of 400 U/L and lipase of 500 U/L are diagnostic for acute pancreatitis, the absolute height of the elevation does not correlate with disease severity. A patient can have severe necrotizing pancreatitis with only mildly elevated enzymes, or very high enzymes with a mild, edematous form. These values confirm the diagnosis but do not indicate severity or the need for immediate intervention beyond standard care.

- Option 3 (Fever and Mild Tachycardia): A temperature of 101.2°F (38.4°C) and mild tachycardia are expected systemic inflammatory response syndrome (SIRS) criteria that frequently accompany acute pancreatitis. They indicate a systemic reaction but are not specific markers of a severe, hemorrhagic, or necrotizing process. These findings warrant monitoring but do not, by themselves, signal the same level of immediate danger as a hemorrhagic sign.

Pathophysiology and Clinical Significance

Grey Turner's sign occurs when retroperitoneal bleeding tracks from the pancreas along fascial planes to the subcutaneous tissue of the flanks, causing visible ecchymosis [2]. This process indicates enzymatic destruction of pancreatic and peripancreatic vasculature, a hallmark of severe necrotizing disease. The sign is rare, observed in

## 임상 시나리오

Severe Pancreatitis AssessmentRecognizing Hemorrhagic vs. Edematous Pancreatitis
Differentiating severe acute pancreatitis from mild edematous pancreatitis relies on clinical signs of retroperitoneal hemorrhage and end-organ failure, not on the magnitude of pancreatic enzyme elevation.

Grey Turner's sign (flank ecchymosis) and Cullen's sign (periumbilical ecchymosis) appear 24-48 hours after onset and indicate severe necrotizing pancreatitis with a high mortality risk.

CautionDo not rely on amylase or lipase levels to determine severity. A patient with necrotizing pancreatitis may have normal or decreasing enzyme levels due to gland destruction. Abdominal rigidity suggests peritoneal involvement and requires urgent surgical evaluation.

## 핵심 개념

- **Grey Turner's sign** — Ecchymosis of the flanks indicating retroperitoneal hemorrhage, a late and severe sign in acute pancreatitis.
- **Acute Necrotizing Pancreatitis** — A severe form of pancreatitis where pancreatic tissue dies, often leading to hemorrhage, infection, and multi-organ failure.
- **Retroperitoneal Hemorrhage** — Bleeding into the retroperitoneal space, which can track to the flanks (Grey Turner's sign) or periumbilical area (Cullen's sign).
- **Serum Lipase** — A pancreatic enzyme more specific than amylase for diagnosing pancreatitis, but its peak level does not indicate disease severity.
- **Peritoneal Irritation** — Inflammation of the peritoneum causing abdominal rigidity or stiffness, often assessed as involuntary guarding.
