Stomach of a Female Child, Gross Anatomy

Description

Centered in the upper abdomen, the pediatric stomach sits mainly in the left hypochondriac and epigastric regions, with the cardia positioned just inferior to the diaphragm and slightly left of the midline as it receives the distal esophagus. The fundus rises superiorly beneath the left hemidiaphragm, while the body tapers toward the pyloric antrum and pylorus, which course inferiorly and to the right to meet the first part of the duodenum. Along the lesser curvature, the stomach’s medial border faces the liver, and the greater curvature sweeps inferolaterally toward the spleen. Surface localization is the point. Fast. Pediatric anatomy changes the way clinicians think about gastric outlet and upper abdominal symptoms, and this view keeps attention on the two terminal regions that matter clinically: the antrum and the pylorus. Hypertrophic pyloric stenosis classically presents with nonbilious projectile vomiting in early infancy, and correlating the pylorus to the right upper quadrant helps explain why ultrasound targets the pyloric canal just to the right of midline. Even in older children, understanding how the antrum transitions to the pylorus guides endoscopy reports and operative descriptions when peptic disease, foreign body passage, or congenital anomalies are in the differential. Use this illustration for pediatric gross anatomy and GI blocks when teaching abdominal surface anatomy, regional localization of pain, and the proximal duodenum as the continuation of the pylorus. It also fits patient education materials and clinical slide decks in pediatric gastroenterology and pediatric surgery, where clear depiction of stomach position supports discussions of pyloromyotomy and upper GI imaging.
