A 63-year-old woman is brought to the emergency department because of severe abdominal pain and vomiting for the past 3 hours. She reports previous episodes of abdominal pain that lasted for 10–15 minutes and resolved with antacids. She lives with her daughter and grandchildren. She divorced her husband last year. She is alert and oriented. Her temperature is 37.3°C (99.1°F), the pulse is 134/min, and the blood pressure is 90/70 mm Hg. The abdomen is rigid and diffusely tender. Guarding and rebound tenderness is present. The rectal examination shows a collapsed rectum. Infusion of 0.9% saline is begun, and a CT of the abdomen shows intestinal perforation. The surgeon discusses with the patient the need for emergent exploratory laparotomy and she agrees to the surgery. Written informed consent is obtained. While in the holding area awaiting emergent transport to the operating room, she calls for the surgeon and informs him that she no longer wants the surgery. He explains to her the risks of not performing the surgery and she indicates that she understands, but is adamant about not proceeding with surgery.
