Stomach of an Obese Male, Gross Anatomy

Description

Centered in the left upper quadrant, the stomach lies inferior to the diaphragm with the gastroesophageal junction just left of the midline and the abdominal esophagus descending through the esophageal hiatus. The fundus domes superiorly beneath the left hemidiaphragm, while the body tapers along the lesser curvature to the angular notch (incisura angularis) before continuing into the antrum and pylorus on the right. A semi-transparent anterior trunk places the gastric silhouette deep to the anterior abdominal wall, with the organ’s long axis running from superolateral left (fundus) to inferomedial right (pyloric region). Orientation is clear. Obesity changes the teaching problem: surface landmarks drift, the left costal margin becomes less reliable, and the stomach’s position is often discussed relative to a fatty liver and an enlarged left upper abdominal pannus rather than a lean abdominal wall. The angular notch matters as a consistent morphological inflection on the lesser curvature, a landmark used when describing endoscopic location along the gastric body-antrum transition and when correlating with sleeve gastrectomy staple line planning that tracks the lesser curvature and incisura region where strictures can occur. An anterior, whole-body context also supports discussions of hiatal hernia and gastroesophageal reflux disease by showing the continuity of the esophagus into the cardia and fundus under the diaphragm. Use this asset for gross anatomy labs, bariatric surgery education, and GI endoscopy teaching materials where learners need organ position in a standing adult male rather than an isolated specimen. It also fits patient-facing diagrams for obesity clinics and publisher layouts covering gastric regions (fundus, body, antrum, pylorus) with the incisura angularis called out along the lesser curvature.
