Yang, Eun, Lee, Chang, Park, and Namgung: A Case of Congenital Gastric Outlet Obstruction with Serosal Fibrous Band in Prematurity

Abstract

Most of the gastric outlet obstruction symptoms like vomiting and abdominal distension were caused by congenital anatomical abnormality in a neonate. Abnormal structures associated with congenital gastric outlet obstruction have been categorized by its site and extent of obstruction. We report one case of persisting vomiting in a premature infant caused by serosal fibrous band in gastric outlet lesion, excluded from the category of congenital gastric outlet obstruction.
