Evaluate the following patients presenting to the emergency department with severe abdominal symptoms. Match each patient's clinical presentation with the most appropriate initial operative or non-operative management strategy.
- A 72-year-old male with a history of atrial fibrillation presents with acute-onset, agonizing abdominal pain that is out of proportion to his benign physical examination. Serum lactate is 4.5 mmol/L.Emergent CT angiography followed by revascularization or resection
- A 55-year-old female with a previous appendectomy presents with crampy abdominal pain, bilious emesis, and obstipation. Her abdomen is distended but non-tender. CT shows dilated small bowel loops with a clear transition point, without free fluid or pneumatosis.Fluid resuscitation, nasogastric tube decompression, and observation
- A 60-year-old male with a history of exploratory laparotomy presents with obstipation, vomiting, and a rigid, peritonitic right lower quadrant. His temperature is 38.8°C (101.8°F) and heart rate is 115/min. White blood cell count is 18,000/mm³.Urgent surgical exploration for suspected bowel strangulation
- A 45-year-old male with chronic osteoarthritis managed with daily ibuprofen presents with sudden-onset, board-like abdominal rigidity. An upright chest radiograph reveals free air under the right hemidiaphragm.Emergent laparotomy with omental patch repair
Cevap
Acute mesenteric ischemia requires emergent CT angiography. Uncomplicated small bowel obstruction requires fluid resuscitation and nasogastric decompression. Complicated (strangulated) small bowel obstruction requires urgent surgical exploration. A perforated peptic ulcer requires emergent laparotomy with omental patch repair.
Each clinical presentation represents a distinct abdominal emergency requiring a specific triage decision. Uncomplicated small bowel obstruction is safely managed conservatively, whereas signs of strangulation mandate urgent surgery. Acute mesenteric ischemia requires vascular evaluation, and a perforated viscus demands emergent primary repair.

Differentiating surgical acute abdomen pathologies is critical to dictate management, which ranges from conservative nasogastric decompression for uncomplicated obstruction to emergent surgical exploration for strangulation or perforation.
