@kaljean my wife has similar size Biloma on her liver. Fistula or drain created from the biloma fortunately created a drainage path right into her bowel. A good thing as infection from the biloma draining elsewhere will certainly be a problem. Long term strong antibiotic therapy and a drain placed near the biloma has helped. Shrunk to 1.1 cm and recently no fluid from the drain indicating it might be stopped finally. Interventional radiology also placed a stent to help with drainage as we also had a small tear in rebuilt bile ducts. The goal with biloma is to shrink it and eliminate it with antibiotics or ant fungal medication and make sure that the fistula or drainage path from it is managed so you are not putting infection back into your body. Sepsis issue tough to deal with and happens fast. Monitor for fever and blood pressure. If either becomes a concern get to the ER fast. Best to you.
