Spontaneous cystic biloma after laparoscopic cholecystectomy treated conservatively: A case report

Introduction: Biloma forms due to common bile duct (CBD) injury as a laparoscopic cholecystectomy complication. Spontaneous localized biloma forming cysts in the biliary duct is rare. Presentation of case: We report a 47-year-old male with complaint of a painful lump in the upper abdomen two months after laparoscopic cholecystectomy. Magnetic resonance cholangiopancreatography (MRCP) found a large epigastric cyst mass, without any signs of CBD injury. Patient was managed with percutaneous drainage in the outpatient clinic and kept the contents of the drainage bag for evaluation. After two months follow-up the outcome was favorable. Discussion: Biloma forming cysts is a very rare complication post laparoscopic cholecystectomy. Biloma most common occurs as free fluid in the abdominal cavity. Clinical diagnostics, intraoperative historical evaluation and support with MRCP may determine the treatment options. Decision to manage with non-operative procedures by percutaneous drainage and evaluations of the patient in the outpatient clinic had a favorable outcome. Conclusion: Post laparoscopic biloma cysts are a very rare case. Management with percutaneous drainage in an outpatient clinic and ambulatory drainage is an effective and safe procedure. © 2021
