What does pneumobilia indicate?
Pneumobilia, or air within the biliary tree of the liver, suggests an abnormal communication between the biliary tract and the intestines, or infection by gas-forming bacteria.
What is the treatment for pneumobilia?
If an infection is the cause of pneumobilia (e.g., emphysematous cholecystitis), broad-spectrum antibiotics (e.g., metronidazole, clindamycin) are suggested as first line treatment.
Is pneumobilia normal?
Pneumobilia is defined as air within the biliary system. It is usually caused by an abnormal connection between the biliary gastrointestinal tracts. Persistent asymptomatic pneumobilia is a rare occurrence and is generally considered a benign finding on imaging.
Is pneumobilia serious?
Pneumobilia, gas within the biliary tract, is due to an abnormal connection between the gastrointestinal tract and the biliary tract and is considered a serious pathology usually requiring surgical intervention.
What is a common cause of pneumobilia?
DISCUSSION. Pneumobilia is a rare condition indicating a passage between the gastrointestinal and biliary systems. This is often perceived as a serious intra-abdominal pathology that requires laparotomy. The most common causes are gallstone disease and consequent biliary-enteric fistula, and biliary tract surgery.
How long does pneumobilia last after ERCP?
After ERCP the presence of air in the biliary tree is an expected, common finding. Intra- and extrahepatic pneumobilia is visible in the majority of patients studied with CT within a few weeks from the procedure and may persist for months or years in patients who underwent sphincterotomy (Fig. 2).
Does pneumobilia need to be treated?
They managed the third patient conservatively, and reached the conclusion that isolated pneumobilia can be treated conservatively. Bautista et al. (4) have found that pneumobilia due to high proximal small bowel obstruction regresses spontaneously with non-operative management by nasogastric decompression.
What causes gas in bile duct?
Gas in the biliary tree is most frequently iatrogenic in nature. In our hospital-based practice, the most common cause of air in the biliary tree is prior sphincterotomy for treatment of common duct stones or stent placement for pancreatic carcinoma.
What causes gas in the bile duct?
Gas in the biliary tract may occur because of a sphincterotomy, or Roux loop procedure, allowing reflux of intestinal gas into the biliary tree. It can be identified by the linear distribution radiating from the hilum and gravity dependence with air predominantly in the non-dependent parts of the biliary tree.
