Difficulty: EasyGastrointestinal and Abdominal Surgery

Match each classic clinical presentation of an acute abdomen with its most appropriate initial management step or definitive treatment.

  • A 48-year-old male who underwent a hernia repair two years ago reports a two-day history of intermittent, crampy abdominal pain, failure to pass flatus, and recent green-tinged vomiting. Imaging shows dilated small bowel loops without pneumoperitoneum.Gastrointestinal decompression via nasogastric tube and intravenous fluid resuscitation
  • A 72-year-old female with persistent atrial fibrillation complains of abrupt, excruciating mid-abdominal pain. Her physical examination is remarkably benign, showing a soft abdomen without guarding or rebound tenderness.Computed tomography angiography (CTA) of the mesenteric vessels
  • A 65-year-old male who takes high-dose ibuprofen daily for osteoarthritis develops sudden, severe generalized abdominal pain. Examination reveals a rigid, board-like abdomen, and an upright X-ray shows subdiaphragmatic radiolucency.Immediate exploratory laparotomy with peritoneal washout
  • A 22-year-old male describes a vague ache around his umbilicus that shifted over 12 hours to become sharp and localized in the right lower quadrant, accompanied by loss of appetite and low-grade fever.Urgent laparoscopic appendectomy

Answer

The small bowel obstruction matches with nasogastric decompression. The mesenteric ischemia matches with CT angiography. The perforated viscus matches with immediate laparotomy. The acute appendicitis matches with urgent appendectomy.
Each classic acute abdomen presentation requires a tailored, evidence-based approach: conservative decompression for uncomplicated adhesive SBO, vascular imaging (CTA) for suspected mesenteric ischemia, immediate surgical exploration for a perforated viscus, and targeted surgical removal for appendicitis.

Step-by-Step Solution

1
Analyze the patient history, vital signs, and physical examination findings for each clinical vignette.
The vignettes describe distinct acute abdominal pathologies: uncomplicated SBO, acute mesenteric ischemia, perforated peptic ulcer, and acute appendicitis.
Identifying the specific etiology of an acute abdomen is critical because management pathways diverge significantly.
2
Match the recognized pathology with the accepted gold-standard initial step or definitive management.
SBO requires conservative management initially, ischemia requires CTA for diagnosis, perforation requires immediate surgical exploration, and appendicitis requires an appendectomy.
Adhering to standard algorithms prevents unnecessary surgeries in some conditions (like early SBO) while avoiding fatal delays in others (like perforation or ischemia).
