Lesser Omentum
Lesser Omentum
A double fold of peritoneum that extends from the lesser curvature of the stomach and proximal part of the duodenum to the liver. It's a key structure in the abdominal cavity.
Omental Bursa
Omental Bursa
A potential space within the abdominal cavity situated behind the stomach and lesser omentum. It's a key landmark for understanding abdominal anatomy.
Epiploic Foramen (Winslow's Foramen)
Epiploic Foramen (Winslow's Foramen)
A small opening that connects the omental bursa to the greater sac of the peritoneal cavity. It's crucial for allowing communication between these two important spaces.

Study Notes
Anatomy of the Omentum
- The peritoneum is a thin serous membrane with parietal and visceral layers.
- It lines the abdominal and pelvic cavities, supporting viscera and providing pathways for blood vessels and lymph.
- The peritoneal cavity is divided into the greater sac and lesser sac (omental bursa).
- Peritoneal folds include omenta, mesenteries, and ligaments.
- The greater omentum is a large peritoneal fold connected to the stomach's greater curvature and extending over the intestines.
- Its boundaries include the greater curvature of the stomach and the transverse colon.
- Key contents include right and left gastroepiploic vessels, lymph nodes, and fat.
- The lesser omentum, smaller, connects the stomach's lesser curvature and the first part of the duodenum to the liver.
- It contains the hepatic artery, bile duct, portal vein, and nerves, among other structures.
- The omental bursa (lesser sac) is a pouch-like space behind the stomach and its boundaries are the posterior layers of the greater omentum, the transverse colon, the ascending portion of the transverse mesocolon, superior surface of the pancreas, the upper ends of the left kidney.
- The epiploic foramen (of Winslow) is a slit-like opening connecting the greater and lesser sacs.
- Its boundaries are the lesser omentum, the first part of the duodenum, the IVC, and the liver.
- The mesentery of the small intestine attaches the small intestine to the posterior abdominal wall.
- Ligaments, including coronary, triangular, and falciform, connect the liver to other organs.
- The mesentery supports the small intestine, while the mesocolon supports the colon.
- The nerve supply to the peritoneum is complex, with parietal peritoneum being sensitive to pain, temperature, touch, and pressure, while visceral peritoneum is only sensitive to stretch and tearing.
Clinical Points
- Peritoneal pain (peritonitis): somatic pain is usually severe and well localized.
- Visceral pain, due to stretch or tension, is usually dull, aching, and poorly localized.
- Clinical considerations relating to pain and disease conditions include ischemia and muscle spasms.
- Peritoneal dialysis is a procedure using the peritoneum as a semipermeable membrane to filter waste products from the blood.
- Medical conditions may require precise surgical interventions with particular locations in the abdomen being crucial for correct diagnosis and treatment.
Other Key Structures
- The epiploic foramen is a crucial communication point between the greater and lesser sacs, with the potential for surgical complications related to strangulated hernias.
- The various regions of the peritoneal cavity exhibit stasis, which are critical points in diagnosing and treating certain gastrointestinal pathologies.
