Text D Abdominal abscesses

Abscesses may form below the diaphragm, in the middle of the abdomen, in the pelvis, or behind the abdominal cavity. Abscesses also may form in or around any abdominal organ, such as the kidneys, spleen, pancreas, or liver, or in the prostate gland. Often, abdominal abscesses are caused by injury, infection or perforation of the intestine, or infection of another abdominal organ.

An abscess below the diaphragm may form when infected fluid, for example, from a ruptured appendix, is moved upward by the pressure of abdominal organs and by the suction created when the diaphragm moves during breathing. Symptoms may include a cough, painful breathing, and pain in one shoulder—an example of referred pain that occurs because the shoulder and the diaphragm share the same nerves and the brain incorrectlv interprets the source of the pain.

Abscess in the midabdomen may result from a ruptured appendix, a perforated large intestine, inflammatory bowel disease, or diverticular disease. The abdomen is usually painful in the area of the abscess.

Pelvic abscesses result from the same disorders that cause abscesses in the midabdomen and from gynecologic infections. Symptoms may include abdominal pain, diarrhea from intestinal irritation, and an urgent or frequent need to urinate caused by bladder irritation.

Abscesses behind the abdominal cavity lie behind the peritoneum, the membrane that lines the abdominal cavity and organs. The causes, which are similar to those of other abscesses in the abdomen, include information of the appendix and of the pancreas. Pain usually in the lower back, worsens when the person moves the leg at the hip.

Abscesses in the kidneys are caused either by bacteria from an infection traveling to the kidneys through the bloodstream or by a urinary tract infection traveling to the kidney and then spreading to the kidney tissue. Abscesses on the surface of the kidneys (perinephric abscesses) are nearly always caused by the rupture of an abscess inside the kidney, which spreads the infection to the surface and the surrounding tissue. Symptoms of a kidney abscess include a fever, chills, and pain in the lower back. Urination may be painful, and sometimes the urine is bloody.

Abscesses in the spleen are caused by an infection traveling through the bloodstream to the spleen, by an injury to the spleen, or by the spread of an infection from a nearby abscess, such as one below the diaphragm. Pain may occur in the left side of the abdomen, the back, or the left shoulder.

Abscesses inside the pancreas typically form after an attack of acute pancreatitis. Symptoms such as fever, abdominal pain, nausea, and vomiting often begin a week or more after a person recovers from pancreatitis.

Liver abscesses may be caused by bacteria or by amebas (single-celled parasites). Amebas from an intestinal infection reach the liver through the lymphatic vessels. Bacteria can reach the liver through the lymphatic vessels. Bacteria can reach the liver from an infected gallbladder; a penetrating or blunt wound; an infection in the abdomen, such as a nearby abscess; or an infection carried by the bloodstream from elsewhere in the body. Symptoms of liver abscessesinclude loss of appetite, nausea, and a fever. A person may or may not have abdominal pain.

Prostate abscesses usually result from a urinary tract infection that leads to a prostate gland infection. These abscesses most commonly occur in men between ages 40 and 60. Typically, a man with a prostate abscess experiences painful, frequent, or difficult urination. Less commonly, he feels internal pain at the base of the penis and notices pus or blood in his urine.
