An intra-abdominal abscess is an infected pocket of fluid and pus located inside the belly area (abdominal cavity). There may be more than one abscess.
Alternative Names:
Abscess - intra-abdominal
Causes, incidence, and risk factors:
An intra-abdominal abscess can be caused by a ruptured appendix, ruptured diverticula, intestinal parasitism (Entamoeba histolytica), or other condition.
Risk factors for intra-abdominal abscess include a history of appendicitis, diverticulitis, perforated ulcer disease, or any surgery that may have infected the abdominal cavity.
Symptoms:
Depending on the location, symptoms may include:
Fever
Chills
Abdominal pain and distention
Weakness
Lack of appetite
Nausea
Vomiting
Rectal tenderness and fullness
Diarrhea
Signs and tests:
The white blood cell count may be elevated on a complete blood count test. A CT scan of the abdomen will usually reveal an intra-abdominal abscess. In addition, after a CT scan, a needle may be placed through the skin into the abscess cavity to confirm diagnosis and treat the abscess. Liver function tests, abdominal x-ray, and sonogram may also be helpful in diagnosing abscess.
Sometimes laparotomy (opening of the abdomen, which is done under general anesthesia) may be necessary for diagnosis.
