Pain Characteristics in Perforated Peptic Ulcer

Primary Pain Characteristics

The World Journal of Emergency Surgery reports that sudden onset of severe upper abdominal pain, typically accompanied by tachycardia and abdominal rigidity, is the hallmark pain presentation of perforated peptic ulcer 1
Sudden onset of abdominal pain is the typical presenting feature of gastroduodenal perforation, according to the World Journal of Emergency Surgery 1, 2

Physical examination findings may be equivocal, and peritonitis may be present in only two-thirds of patients with perforated peptic ulcer, as noted by the World Journal of Emergency Surgery 1, 2
Peritonitis may be minimal or absent, particularly in patients with contained or sealed perforations, according to the World Journal of Emergency Surgery 1, 2
Localized or generalized peritonitis is typical but not universal, as reported by the World Journal of Emergency Surgery and Praxis Medical Insights 1, 3

The World Journal of Emergency Surgery and Praxis Medical Insights strongly recommend CT scan as the first-line imaging when a patient presents with suspected perforated peptic ulcer based on pain characteristics (Strong recommendation, 1C) 1, 2, 3
Chest/abdominal X-ray should be performed initially only when CT is not promptly available, as recommended by the World Journal of Emergency Surgery and Praxis Medical Insights (Strong recommendation, 1C) 1, 2, 3
Routine laboratory studies and arterial blood gas analysis are strongly recommended, though findings are non-specific, according to the World Journal of Emergency Surgery and Praxis Medical Insights 1, 2, 3
Leukocytosis, metabolic acidosis, and elevated serum amylase are commonly associated but non-specific findings, as reported by the World Journal of Emergency Surgery and Praxis Medical Insights 1, 4
