Overview
Pancreatic abscess is an unusual and rare, but life threatening complication of acute pancreatitis.
Definition
Historical Perspective
Causes
Common Causes
Common organisms causing pancreatic abscess are as follows:[1]
Aerobic bacteria
- Enterococcus
- Escherichia coli
- Klebsiella pneumoniae
- Pseudomonas aeruginosa
- Staphylococcus aureus
Anaerobic bacteria
- Bacteriodes fragilis
- Clostridium perfringens
Differentiating Pancreatic Abscess from other Diseases
Pancreatic abscess should be diagnosed early and treat promptly not only to reduce morbidity and mortality, but also it is important to differentiate from other pancreatic disesases such recurrent pancreatitis, pancreatic psuedocysts etc. as the undrained abscess carreies high risk of mortality.[2]
- Recurrent pancreatitis
Natural History, Complications and Prognosis
Complications
- Intra abdominal sepsis
Gastric complications
- GI bleeding
- Gastric outlet obstruction
Colon complications
Diagnosis
History and Symptoms
Common Symptoms
Presenting symptoms of pancreatic abscess are vague and variable, but common symptoms include:[1]
Less common symptoms
Vital signs
- High grade fever (greater than 37.8°C)
- Upper abdominal pain
- Failure to thrive
Physical Examination Findings
- Abdominal tenderness[1]
- Abdominal mass
- Abdominal distention
Lab Findings
- Leukocytosis (range between 10,500 to 35,00O/mm3)
Imaging
Imaging studies are crucial in the diagnosis and treatment of pancreatic abscess.
X-ray
- Shows extraluminal gas bubbles suggesting abscess
Ultrasound
- Shows fluid filled sac suggesting abscess
