The Walls of the Stomach and Duodenum

  • Albertus D. Keet


At upper abdominal operations, with the organs in situ, a slight groove may be seen in the glistening serosal surface at the gastroduodenal junction. In the groove a small, superficial subserosal vein, lying vertically across the front of the gut, may be evident; this is the prepyloric vein, draining into the right gastric vein (Chap. 7). The groove and the prepyloric vein indicate the position of the pyloric ring. At palpation a sudden transition is felt at the ring between the thick walls of the pyloric region and the thin walls of the duodenum.
