Peritoneal Studding

Peritoneal Studding And What It Is

Certain types of abdominal cancer, for example carcinomatosis, which is growth of tumors along the peritoneum, can manifest in cancerous nodules which are known as peritoneal studding.

The cavity of the abdomen, also called the coelom, which is the space surrounded by the abdominal muscles, diaphragm, vertebrae, and pelvic floor, is lined with a membrane which is properly called the peritoneum. This is a serous membrane, also known as a serosa, and covers the coelomic, or intra-abdominal, organs which are also called the viscera.

Carcinomatosis, or tumor growth on the peritoneum, can range from being one tiny nodule located along the peritoneum, only millimeters in diameter, to manifesting as a lot of tiny nodules, which is referred to as peritoneal studding, to large tumors, the size of golf balls or even soft balls, scattered all over the abdomen.

This tumor growth is usually not curable, because the existence of the nodules means the disease is elsewhere as well.

Peritoneal mesothelioma also affects this area and is fairly rare. Primary mesothelioma of the peritoneum accounts for ten to twenty percent of all mesotheliomas. It seems this type may have something to do with asbestos. There is no specific list or collection of symptoms, however most patients complain of pain in the abdomen, distension of the abdomen, and weight loss. Onset is usually between the ages of forty five and sixty five years, with a period of latency between twenty and forty five years.

Diagnosis is normally done via biopsy as well as CT and MRI scanning. The imaging can show peritoneal studding and mesenteric thickening. There is no standard, specific treatment for this disease. Various types of treatment have been tried both alone and in different combinations. These include radiation therapy, chemotherapy, and surgical resection. All have been met with little success, and survival is typically less than one year.
