Differential Diagnosis for 83 YOM with Intractable Vomiting

Single Most Likely Diagnosis

  • Gastroesophageal Reflux Disease (GERD) or Gastritis: Given the patient's age and the fact that vomiting is intractable despite zofran (an antiemetic), a gastrointestinal cause such as GERD or gastritis is plausible. These conditions can cause persistent vomiting and may not respond immediately to antiemetics alone.

Other Likely Diagnoses

  • Gastroparesis: This condition, characterized by delayed stomach emptying, can cause intractable vomiting. The patient's age and the fact that metoclopramide (a prokinetic agent) is considered, suggest that gastroparesis could be a likely diagnosis.
  • Small Bowel Obstruction: Although less common, small bowel obstruction can cause intractable vomiting and should be considered, especially if there are other symptoms such as abdominal pain or distension.
  • Medication Side Effects: Certain medications can cause vomiting as a side effect. Given the patient's age, polypharmacy could be an issue, and reviewing the patient's medication list is essential.

Do Not Miss Diagnoses

  • Myocardial Infarction: Vomiting can be a presenting symptom of myocardial infarction, especially in the elderly. The patient's heart rate of 51 BPM, although not immediately concerning, in the context of intractable vomiting, warrants consideration of cardiac causes.
  • Appendicitis: Although less common in the elderly, appendicitis can present atypically with vomiting as a primary symptom. Missing this diagnosis could lead to severe consequences.
  • Increased Intracranial Pressure: Vomiting can be a sign of increased intracranial pressure, which could be due to various causes including stroke, hemorrhage, or tumor. This diagnosis is critical not to miss due to its potential for severe outcomes.

Rare Diagnoses

  • Cyclic Vomiting Syndrome: A rare condition characterized by recurrent episodes of severe vomiting, which could be considered if other diagnoses are ruled out.
  • Rapid Gastric Emptying (Dumping Syndrome): Typically seen in patients post-gastric surgery, this condition can cause vomiting after eating and might be considered in the appropriate clinical context.
  • Neurological Disorders (e.g., Vestibular Disorders): Certain neurological conditions can cause vomiting, and while rare, they should be considered if other diagnoses are excluded.
