Juxtapyloric

Juxtapyloric: The prefix "juxta-" comes from the Latin preposition meaning near, nearby, close. Juxtapyloric thus means near the pylorus (the muscular area at the junction of the stomach and the first part of the small intestine, the duodenum).

To speak of a juxtapyloric ulcer is to put the location of the ulcer near the pylorus.
