Difficulty: EasyGastrointestinal and Abdominal Surgery

Match each classic clinical presentation of an acute surgical abdomen to the most likely diagnosis.

  • A 42-year-old woman presents with steady right upper quadrant pain, fever, and leukocytosis. Examination reveals inspiratory arrest upon deep palpation of the right subcostal area.Acute cholecystitis
  • A 22-year-old man presents with anorexia and vague periumbilical pain that later localizes to the right lower quadrant with guarding and rebound tenderness.Acute appendicitis
  • A 68-year-old man with chronic osteoarthritis presents with sudden-onset, severe, diffuse abdominal pain. Examination shows board-like rigidity, and an upright chest x-ray reveals pneumoperitoneum.Perforated peptic ulcer
  • A 55-year-old woman with a history of an open appendectomy presents with crampy abdominal pain, bilious vomiting, and high-pitched 'tinkling' bowel sounds on auscultation.Small bowel obstruction

Answer

1 matches with Acute cholecystitis, 2 matches with Acute appendicitis, 3 matches with Perforated peptic ulcer, and 4 matches with Small bowel obstruction.
Each clinical scenario provides classic, pathognomonic historical and physical examination findings that directly correlate to a specific acute surgical abdomen diagnosis. Recognizing these foundational patterns allows for accurate and rapid clinical triage.

Step-by-Step Solution

1
Analyze the first clinical vignette.
The patient has right upper quadrant pain, fever, and a positive Murphy sign.
These findings are highly specific for gallbladder inflammation and cystic duct obstruction.
2
Analyze the second clinical vignette.
The patient demonstrates the classic migratory pain pattern from the periumbilical region to the right lower quadrant, accompanied by anorexia and rebound tenderness.
This progression of symptoms points to early visceral pain from luminal obstruction followed by somatic pain from localized parietal peritoneal inflammation.
3
Analyze the third clinical vignette.
The patient has acute diffuse peritonitis and pneumoperitoneum in the setting of chronic NSAID use.
Free air indicates a hollow viscus perforation, typically a duodenal or gastric ulcer in a patient with risk factors like osteoarthritis requiring NSAIDs.
4
Analyze the fourth clinical vignette.
The patient exhibits obstructive symptoms with high-pitched bowel sounds and a surgical history.
Prior abdominal surgery predisposes to intra-abdominal adhesions, which are the most common cause of mechanical small bowel obstruction.

Key Concept

Identifying classic clinical presentations of common surgical emergencies based on history and physical examination is essential for prompt diagnosis and appropriate intervention.
