Partial or complete absence of the abdominal muscles so that the outlines of the intestines are visible through the thin, lax, protruding abdominal wall. Also called the “prune belly syndrome.” The full syndrome probably occurs only in males. In addition to the abdominal muscle deficiency, there are genital and urinary abnormalities including dilation (widening) of the urinary…

Surgical removal of the uterus (a hysterectomy) done through an incision made in the abdominal wall. This may also be done by laparoscopy. As opposed to a vaginal hysterectomy, in which the incision is made within the vagina.

Tensing of the abdominal wall muscles to guard inflamed organs within the abdomen from the pain of pressure upon them. Abdominal guarding is detected when the abdomen is pressed and is an indication that inflammation of the inner abdominal (peritoneal) surface may be present due, for example, to appendicitis or diverticulitis. The tensed muscles of the abdominal wall automatically go…

The cavity within the abdomen, the space between the abdominal wall and the spine. The abdominal cavity is hardly an empty space. It contains a number of crucial organs including the lower part of the esophagus, the stomach, small intestine, colon, rectum, liver, gallbladder, pancreas, spleen, kidneys, and bladder.

A balloon-like swelling in the wall of the aorta within the abdomen. This swelling weakens the aorta’s wall and, because of the great volume of blood flowing under high pressure in the aorta, it can rupture. An abdominal aortic aneurysm is monitored by ultrasound. Surgery is often recommended if the aneurysm is more than 5.5 centimeters (2.2 inches) in diameter or if…

The abdominal aorta is the final section of the aorta, the largest artery in the body. It is a continuation of the thoracic aorta. It begins at the diaphragm, and runs down to the point where it ends (by splitting in two to form the common iliac arteries). The abdominal aorta supplies oxygenated blood to all…

An aneurysm situated within the abdomen (belly). An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture. The word “aneurysm” comes from the Greek “aneurysma” meaning “a widening.” An aneurysm may involve the aorta, the largest…

Relating to the abdomen, the belly, that part of the body that contains all of the structures between the chest and the pelvis. The abdomen is separated anatomically from the chest by the diaphragm, the powerful muscle spanning the body cavity below the lungs. The abdomen includes a host of organs including the stomach, small intestine, colon, rectum, liver, spleen,…

Medical shorthand for the acute onset of abdominal pain. A potential medical emergency, an acute abdomen may reflect a major problem with one of the organs in the abdomen, such as appendicitis (inflamed appendix), cholecystitis (inflamed gallbladder), a perforated ulcer in the intestine, or a ruptured spleen.
