Peritonitis

 


Risk factors for Peritonitis

Digestion  

Gastric/Peptic Ulcers

Sometimes an ulcer eats a hole in the wall of the stomach or duodenum. Bacteria and partially digested food can spill through the opening into the sterile abdominal cavity, called the peritoneum. This causes peritonitis, an inflammation of the abdominal cavity and wall. A perforated ulcer usually requires immediate hospitalization and surgery.

Glossary

Ulcer

Lesion on the skin or mucous membrane.

Stomach

A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach’s mucous lining must constantly regenerate itself.

Duodenum

First portion of the small intestine between the pylorus and jejunum.

Bacteria

Microscopic germs. Some bacteria are "harmful" and can cause disease, while other "friendly" bacteria protect the body from harmful invading organisms.

Peritoneum

Serous sac lining the abdominal cavity and covering most of the organs inside it.
