What is the meaning of peritoneal spill?

Peritoneal spill refers to the presence of fluid or substances within the peritoneal cavity, which is the space within the abdomen that houses various organs. This phenomenon can be observed during medical imaging or surgical procedures, often indicating the presence of conditions such as infection, inflammation, or malignancy. In some cases, a peritoneal spill can also occur during procedures like laparoscopy, where fluid is intentionally introduced for examination. Overall, it serves as a diagnostic indicator of underlying abdominal issues.
