Introduction: Transjugular intrahepatic portosystemic shunt (TIPS) is a minimally invasive procedure and an effective therapeutic option for managing portal hypertension complications. Biliary complications after TIPS are uncommon. Here we present a case of recurrent perihepatic biloma in a woman who underwent TIPS.
Case Description/Methods: A 40-year-old woman was admitted for epigastric abdominal pain for five days. She reported taking oral contraceptive pills (OCPs) for one month before presentation. She had epigastric tenderness on examination and normocytic anemia (Hgb 10 g/L) on admission labs. CT scan of the abdomen showed a large thrombus in the main portal vein extending into the right and left portal venous branches. The patient was started on heparin drip and underwent TIPS with thrombectomy. Hypercoagulability workup was unremarkable. The post-procedure course was complicated by elevation of alkaline phosphatase (552 U/L), AST (293 U/L), and ALT (324 U/L). Abdomen MRI showed patent TIPS and persistent complete thrombosis of all intrahepatic portal venous branches. She underwent repeat thrombolysis. However, liver enzymes continued to rise, and a repeat MRI showed intrahepatic biloma at the mid aspect of TIPS (Figure 1A, B). IR-guided drainage of the biloma was performed. The hospital course was complicated by fever and leukocytosis. A follow-up CT scan showed a 13 cm complex fluid collection at the dome of the liver (Figure 2A). She underwent drainage of the new collection and received IV Cefoxotin with an interval decrease in the collection size (Figure 2B). Fever resolved, and liver enzymes normalized.
Discussion: Bilomas are either intra- or extrahepatic collections of bile that can occur spontaneously, or as a result of trauma to the biliary tree, including iatrogenic injury. Bilomas are usually asymptomatic but may present with abdominal pain due to symptomatic bile peritonitis or secondary bacterial infection leading to abscess formation and sepsis. A biloma may wall off or may continue to have active bile leakage. CT intravenous cholangiography, MRI with gadolinium, and Tc99 scintigraphy can identify bile leak. Differential diagnoses include hepatic cyst and hematoma, liver abscess, loculated ascites, and postoperative fluid collections, including seroma and lymphocele. Treatment options include endoscopic drainage, IR guided, or surgical drainage with bile leak repair.
