A 72-year-old lady appears at the emergency department with acute right lower abdominal and rectal discomfort that has been present for the previous week. She has a history of narcotic bowel syndrome and many prior abdominal surgeries. She claims no fevers, chills, nausea, vomiting, diarrhoea, bleeding or melena, hematuria, dysuria, or other symptoms. A big faeces ball is discovered during a rectal examination. Initial diagnostic testing includes blood tests and an abdominal computed tomography scan (Figure).
