Clinical Information

• Chylous Ascites-. presence of milky lymph (chyle) in the peritoneal cavity, with or without infection.
• Coronavirus, Feline-. a species of coronavirus infecting cats of all ages and commonly found in catteries and zoos. cats are often found carrying the virus but only a small proportion develop disease. feline coronavirus and feline infectious peritonitis virus (fipv) are virtually the same virus in genetic and antigenetic terms, and are morphologically indistinguishable. since they only differ in their disease potential (with fipv causing a more serious illness), they are considered biotypes of each other.
• Familial Mediterranean Fever-. a group of hereditary autoinflammation diseases, characterized by recurrent fever, abdominal pain, headache, rash, pleurisy; and arthritis. orchitis; benign meningitis; and amyloidosis may also occur. homozygous or compound heterozygous mutations in marenostrin gene encoding pyrin result in autosomal recessive transmission; simple heterozygous, autosomal dominant form of the disease also exists with mutations in the same gene.
• Feline Infectious Peritonitis-. common coronavirus infection of cats caused by the feline infectious peritonitis virus (coronavirus, feline). the disease is characterized by a long incubation period, fever, depression, loss of appetite, wasting, and progressive abdominal enlargement. infection of cells of the monocyte-macrophage lineage appears to be essential in fip pathogenesis.
• Peritonitis-. inflammation of the peritoneum lining the abdominal cavity as the result of infectious, autoimmune, or chemical processes. primary peritonitis is due to infection of the peritoneal cavity via hematogenous or lymphatic spread and without intra-abdominal source. secondary peritonitis arises from the abdominal cavity itself through rupture or abscess of intra-abdominal organs.
• Peritonitis, Tuberculous-. a form of peritonitis seen in patients with tuberculosis, characterized by lesion either as a miliary form or as a pelvic mass on the peritoneal surfaces. most patients have ascites, abdominal swelling, abdominal pain, and other systemic symptoms such as fever; weight loss; and anemia.
• Serositis-. inflammation of a serous membrane.
• Typhlitis-. necrotizing inflammation of the cecum ("typhlon" in greek), sometimes spreading to the appendix and/or the ileum. symptoms include abdominal pain and diarrhea. its pathogenesis is multifactorial. typhlitis is often associated with neutropenia and chemotherapy in immunocompromised individuals (immunocompromised host).
• Ovarian Luteinized Thecoma Associated with Sclerosing Peritonitis-. a rare usually bilateral luteinized thecoma that arises from the ovary and is associated with sclerosing peritonitis. it occurs mostly in premenopausal women. the ovarian tumor is benign but patients may develop intestinal obstruction due to the sclerosing peritonitis.
• Sclerosing Peritonitis-. a rare peritoneal cavity disorder that is characterized by the development of dense fibrous tissue in the peritoneum and the creation of severe adhesions in the abdomen that result in partial or complete small bowel obstruction. it may be idiopathic or develop in patients who receive peritoneal dialysis treatment. patients present with abdominal distention and pain.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Peritoneal Disorders

Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.

Disorders of the peritoneum are not common. They include:

• Peritonitis - an inflammation of the peritoneum
• Cancer
• Complications from peritoneal dialysis

Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
