## 문제

The nurse is conducting a comprehensive assessment on a patient presenting with vague abdominal symptoms and unexplained weight loss. Which assessment finding would be most indicative of advanced pancreatic adenocarcinoma?

## 보기

1. Epigastric pain that improves with eating
2. Clay-colored stools with steatorrhea
3. Painless jaundice with palpable gallbladder **✔ 정답**
4. Right upper quadrant tenderness with Murphy's sign

**정답: 3**

## 해설

Painless jaundice with palpable gallbladder (Courvoisier's sign) is a classic triad indicating advanced pancreatic adenocarcinoma, especially in head tumors causing bile duct obstruction. Other options are more typical of benign conditions like peptic ulcer disease (choice 1) or cholecystitis (choice 4).

Understanding the Clinical Presentation of Advanced Pancreatic Adenocarcinoma

The question asks you to differentiate the hallmark signs of advanced pancreatic adenocarcinoma from other hepatobiliary or gastrointestinal conditions. Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy that is frequently diagnosed at an advanced stage, often presenting with nonspecific symptoms [3][4]. The classic and most indicative finding for a tumor located in the head of the pancreas is the combination of painless jaundice and a palpable gallbladder, known as Courvoisier's sign.

Analysis of the Correct Answer (Option 3)

Painless jaundice with palpable gallbladder is correct because of the tumor's anatomical location and pathophysiology. A tumor in the head of the pancreas can compress the common bile duct, obstructing the flow of bile. This leads to a buildup of bilirubin, causing jaundice. Because the obstruction is distal to the cystic duct, bile backs up into the gallbladder, causing it to distend. In the absence of gallstone disease (which typically causes painful inflammation), this distension is painless and the gallbladder becomes palpable below the right costal margin. This specific constellation of signs is highly suggestive of a malignant obstruction, most commonly pancreatic cancer.

Analysis of Incorrect Options

- Option 1: Epigastric pain that improves with eating. This pattern is more characteristic of duodenal ulcer disease. In pancreatic cancer, pain is a common but nonspecific symptom [1]. When present, it is often described as a dull, gnawing epigastric pain that radiates to the back and may be worse when lying supine or after eating, not improved by it.

- Option 2: Clay-colored stools with steatorrhea. These are signs of biliary obstruction and pancreatic exocrine insufficiency, respectively. While they can occur in advanced pancreatic cancer, they are not the most indicative finding. Clay-colored stools result from a lack of bilirubin reaching the GI tract, and steatorrhea (fatty, foul-smelling stools) occurs when over 90% of the pancreatic exocrine function is lost. These findings suggest a chronic process but lack the specific, highly suggestive physical exam finding of a palpable, non-tender gallbladder.

- Option 4: Right upper quadrant tenderness with Murphy's sign. This is the classic physical exam finding for acute cholecystitis. Murphy's sign is elicited when the patient abruptly stops inspiration due to pain as the examiner's hand palpates the inflamed gallbladder. This indicates an inflammatory process of the gallbladder wall, almost always due to cystic duct obstruction by a gallstone, not a malignant distal obstruction.

Connecting Clinical Signs to Pathophysiology

The rationale for the correct answer is rooted in the tumor's growth pattern. As noted in the provided literature, pancreatic adenocarcinoma typically presents late with nonspecific symptoms like weight loss and abdominal pain [1]. The development of a palpable, painless gallbladder in a jaundiced patient is a late, but critically specific, physical finding that points directly to a slow-growing malignant obstruction of the common bile duct, bypassing the painful inflammatory phase seen with stone disease. This distinction is a high-yield concept for the NCLEX-RN, testing your ability to link a specific physical assessment finding to its most likely underlying pathology.References (research sources)

## 임상 시나리오

Courvoisier's Law in Clinical AssessmentDifferentiating Malignant vs. Stone Obstruction
A painless, palpable gallbladder accompanied by jaundice is highly indicative of a malignant obstruction, most commonly from a tumor in the head of the pancreas. This is known as Courvoisier's sign.

In contrast, a gallbladder obstructed by gallstones is typically non-palpable due to chronic inflammation and fibrosis. If a stone causes acute cholecystitis, the patient will present with pain and a positive Murphy's sign, not a painless mass.

CautionDo not rely solely on the absence of pain. A palpable gallbladder in a jaundiced patient is a red flag requiring urgent imaging, such as a CT scan or MRCP, to rule out malignancy.

## 핵심 개념

- **Courvoisier's sign** — A palpable, non-tender gallbladder in a jaundiced patient, suggesting malignant obstruction of the common bile duct rather than gallstone disease.
- **Steatorrhea** — Excess fat in feces, appearing pale, bulky, and foul-smelling, often due to pancreatic exocrine insufficiency preventing fat digestion.
- **Murphy's sign** — Pain and inspiratory arrest upon palpation of the right upper quadrant during inspiration, indicative of acute cholecystitis.
- **Painless jaundice** — Yellowing of the skin and sclera without biliary colic, a classic red flag symptom for periampullary tumors like pancreatic adenocarcinoma.
- **Common bile duct obstruction** — Blockage of the duct carrying bile from the liver and gallbladder to the duodenum, leading to jaundice, dark urine, and pale stools.
