This page is dedicated to organizing various examples of standardized exam questions whose answer is sigmoid volvulus. While this may seem a odd practice, it is useful to see multiple examples of how sigmoid volvulus will be characterized on standardized exams (namely the boards and the shelf exams). This page is not meant to be used as a traditional question bank (as all of the answers will be the same), however seeing the classic “test” characterization for a disease is quite valuable.
Question # 1
A 85 year old male presents with nausea, vomiting, and abdominal pain. He has not passed any gas or stool for the past 24 hours. A physical exam reveals abdominal distention, a tympanic abdomen, and hyperactive bowel sounds. A KUB study shows distended loops of small and large bowel, and a very large gas shadow int he right upper quadrant that tapers toward the left lower quadrant. This gas patter appears to mimc the shape of a parrot’s beak.
