Lesser Omentum Obstruction

Lesser omentum obstruction is a rare but serious medical condition involving the lesser omentum, a part of the abdominal cavity. Understanding its anatomy, causes, symptoms, and treatments is crucial for timely diagnosis and management. This guide aims to provide a clear and comprehensive overview of lesser omentum obstruction in simple language.

The lesser omentum is a double layer of peritoneum (a thin membrane) that connects the liver to the stomach and the first part of the small intestine (duodenum). It plays a role in supporting the organs within the abdomen and contains important blood vessels, nerves, and lymphatics.

Anatomy of the Lesser Omentum

Structure

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

Components

• Blood Vessels: Provide blood supply to the liver, stomach, and duodenum.
• Nerves: Facilitate communication between the brain and abdominal organs.
• Lymphatics: Drain lymph fluid from the stomach and liver.

Types of Lesser Omentum Obstruction

Lesser omentum obstruction can be categorized based on the location and cause:

1. Superior Obstruction: Near the liver and stomach.
2. Inferior Obstruction: Near the duodenum.
3. Acute Obstruction: Sudden onset, often due to trauma or acute inflammation.
4. Chronic Obstruction: Gradual development, commonly from tumors or fibrosis.

Causes of Lesser Omentum Obstruction

Here are 20 potential causes:

1. Abdominal Trauma: Injury to the abdomen can damage the lesser omentum.
