For pediatric patients see Abdominal pain (peds). See also abdominal pain (geriatrics) and Abdominal pain in pregnancy.

Background

  • Patients with immunosuppression often have delayed or atypical presentations
  • Fever is not a reliable marker for surgical disease
  • Abdominal pain may be particularly misleading in elderly or diabetics
  • Consider pain in any abdominal or pelvic region in a female of child-bearing age, including pre-teens, is an ectopic pregnancy until proven otherwise

Clinical Features

  • Abdominal pain (see workup by location)
  • May be associated with nausea, vomiting or diarrhea
  • Fever may be present in pain from infectious etiology

Management

  • Treat underlying cause
  • Multiple studies show pain medicine should not be withheld for fear of masking symptoms

Disposition

  • Depends on etiology
  • The two most notoriously missed conditions are appendicitis and small bowel obstruction.[2]. When discharging patients with abdominal pain, clear instructions should be given for return if there are red flags.
