Clinical Information for Other disorders of peritoneum (K66)

Hemoperitoneum - Accumulations of blood in the PERITONEAL CAVITY due to internal HEMORRHAGE.

Pneumoperitoneum - A condition with trapped gas or air in the PERITONEAL CAVITY, usually secondary to perforation of the internal organs such as the LUNG and the GASTROINTESTINAL TRACT, or to recent surgery. Pneumoperitoneum may be purposely introduced to aid radiological examination.

Pneumoperitoneum, Artificial - Deliberate introduction of air into the peritoneal cavity.

Mesenteric Cyst - A rare intra-abdominal tumor in the MESENTERY. Mesenteric cysts are usually benign and can be very large fluid-filled (2000 mL) lesions.

Peritoneal Fibrosis - Disorder characterized by a wide range of structural changes in PERITONEUM, resulting from fibrogenic or inflammatory processes. Peritoneal fibrosis is a common complication in patients receiving PERITONEAL DIALYSIS and contributes to its gradual decrease in efficiency.
