  • “Gallstone ileus (GI) represents a small percentage (0.4–5%) of a range of causes of mechanical intestinal bowel obstruction. It predominantly affects the elderly patient population; 25% are adults over 65 years old. It affects more commonly in the elderly female with an average age of 65–75 years and female–male ratio of 4–7:1. Cases of GI have been reported in as young as 13 years old up to the oldest of 91 years old. Despite the rare incidence, it carries a mortality and morbidity rate of around 7–30%. This is mainly due to the patient’s demographics and delayed diagnosis or misdiagnosis.”

  • “Our Emergency physicians do not see that oral contrast administration for CT hampers operational efficiency; in fact, they have expressed gratitude to our department for care in diagnosis. They have stated that delays in patient turnaround are more frequently related to overall demand on the scanner and not to the oral contrast consumption period. They are all acutely aware of the serious consequences of missed or incorrect diagnoses (either leading to inappropriate hospital admission or discharge), and will always choose good medical care over time slashing, corner cutting methods that impress the dashboard monitors perhaps at the expense of excellence in patient care.”
