Background

The peritoneum is a thin, transparent, serous membrane, being the largest and most complex arranged serous membrane in our body. It has 2 layers: the parietal and visceral peritoneum. The visceral peritoneum lines all the organs that are intraperitoneal. While the parietal peritoneum lines the majority of the walls of the abdominal cavity. The potential space created between them is called the peritoneal space.

Various terms are used to describe parts of the peritoneum that connect organs with other organs or to the abdominal wall:

  • A ligament is formed by two folds of the peritoneum, which supports a structure within the peritoneal cavity and is named according to the structures it connects (ie Gastrocolic ligament)
  • A mesentery - Connects the intestine to the posterior peritoneal cavity, and acts as a channel for neurovascular and lymphatic structures between the organ and posterior abdominal wall. They include the small intestine mesentery, the transverse mesocolon and the sigmoid mesocolon
  • The omenta or "false mesenteries" are specialized mesenteries that do not attach to the posterior peritoneal wall.
    • Greater Omentum (attaches the stomach to the transverse colon)
    • Lesser Omentum (attaches the liver to the stomach)
    • Mesoappendix (attaches the appendix to the ileum)
