In the context of GI disorders, what does "peritonitis" refer to?

Peritonitis refers specifically to the inflammation of the peritoneum, which is the serous membrane lining the abdominal cavity and covering the abdominal organs. This condition can result from various causes, including infection, perforation of abdominal organs, or inflammatory diseases. The inflammation can lead to significant abdominal pain, tenderness, and potentially severe complications if not treated promptly, such as sepsis or organ failure. Understanding this definition is crucial for recognizing the symptoms and required urgent intervention in patients presenting with signs of peritonitis. The other terms relate to different aspects of gastrointestinal disorders, such as dilation or absence of bowel sounds, but do not encompass the specific definition of peritonitis.
