The average length of the adult human small intestine is approximately 600 cm, as calculated from studies performed on cadavers. According to Lennard-Jones and to Weser, this figure ranges from 260-800 cm.[1] Any disease, traumatic injury, vascular accident, or other pathology that leaves less than 200 cm of viable small bowel or results in a loss of 50% or more of the small intestine places the patient at risk for developing short-bowel syndrome.
