Final clinical long case 15

Created: 8/2/2006
 
A 79-year-old female presents with lower abdominal pain, nausea and vomiting of 24 hours’ standing. She is admitted onto a ward and treated with analgesics and fluids, but the pain is still present. She underwent hemithyroidectomy 2 years ago and now, on examination, a large goitre is found with inspiratory stridor, although the patient is not in acute distress. The surgeon wants to take her to theatre to see if there is a large bowel obstruction.
