Lesser Omentum Diseases

Anatomy of the Lesser Omentum

The lesser omentum is a double-layered fold of the peritoneum? (the lining of the abdominal cavity?) that connects the liver? to the stomach and the first part of the small intestine? (duodenum?). It plays a vital role in supporting these organs and contains important blood vessels, nerves, and lymphatics.

Key Structures:

• Hepatogastric Ligament?: Connects the liver to the stomach.
• Hepatoduodenal Ligament: Connects the liver to the duodenum and contains the portal vein?, hepatic artery?, and common bile duct?.
