"The first (superior) part of the duodenum begins as a continuation of the duodenal end of the pylorus. It passes laterally to the right, superiorly and posteriorly, for approximately 5 cm, before making a sharp curve inferiorly into the superior duodenal flexure. It is intraperitoneal for the first 2-3 cm only. Relations 3:"
