Clinical information

An abdominal abscess is a pocket of infected fluid and pus located inside the belly area (abdominal cavity). Let's examine some detailed clinical information about this condition:

An abdominal abscess may occur after surgery or injury, or it could be an infection or illness complication.
This abscess is commonly caused by appendicitis, diverticulitis, Crohn's disease, pancreatitis, pelvic inflammatory disease, or a perforated bowel.
Symptoms can include pain or discomfort in the abdomen/digestive system, loss of appetite, nausea, vomiting, and fever.
Diagnosis often involves imaging tests like ultrasound, CT scan, or MRI. Sometimes, an abscess is found during surgery for another condition.
Treatment typically involves antibiotics and drainage of the abscess, usually performed using a long needle under imaging guidance or during surgery.

Synonyms include

Commonly asked questions

An abdominal abscess often arises due to an infection or inflammation within an organ in the abdomen. These can be caused by appendicitis, diverticulitis, or Crohn's disease. Abdominal surgery can also sometimes lead to abscess formation.

Treatment for an abdominal abscess primarily involves drainage of the abscess and antibiotics. The drainage can be done using a long needle and syringe, usually guided by ultrasound or CT scan, or during surgery in some instances.

If left untreated, an abdominal abscess can lead to severe complications, including sepsis, a life-threatening infection that can spread through your body. Hence, seeking medical attention promptly is essential if an abscess is suspected.
