Biliary ascites due to spontaneous biliary duct perforation is a rare case presentation usually seen in the paediatric age group of 6-36 months. We are presenting the case of a 14-month-old baby with abdominal distention associated with abdominal pain, vomiting, fever, and a history of no passage of stools. Upon examination, the abdomen was tense and tender. On radiological investigations, gross free fluid was present in the abdominal cavity along with bowel obstruction and partial situs inversus of the spleen and stomach. The bowel obstruction was relieved by rectal stimulation, after which oral feeds were well tolerated. Bilious fluid was found on diagnostic paracentesis, confirming the diagnosis. The patient was managed further by broad-spectrum antibiotics and drainage of the free fluid. The management ranges from conservative treatment to Roux-en-Y anastomosis. A non-surgical diagnosis is uncommonly seen and helps improve the patient\'s prognosis if detected early. This case report highlights the importance of early diagnosis and non-surgical treatment modality in critical patients.

Biliary atresia is one of the most challenging conditions in pediatric surgery even when it is the only finding. Here we present a rare case of biliary atresia complicated with biliary ascites due to ductal perforation identified on a hepatobiliary iminodiacetic acid (HIDA) scan.

\"Biloma\" is a collection of bile outside of the biliary tree that could occur postoperatively in patients who undergo laparoscopic cholecystectomy or in patients with blunt trauma to the liver. Spontaneous or impulsive bilomas with no identifiable cause occur rarely. We report a case of a 60-year-old woman with no history of hepatobiliary surgery or trauma, who was admitted for right upper quadrant pain. An abdominal examination revealed tenderness in the right upper quadrant (RUQ). Her alkaline phosphatase level was 2,343 IU/L. Computed tomography of the abdomen and pelvis with contrast showed perihepatic, periduodenal, and right paracolic gutter ascites. The image-guided aspiration of the peritoneal cavity yielded greenish fluid that was determined to be bile. The cytological studies were negative for malignancy and microorganisms. The ultrasound images of the RUQ were negative for cholecystitis and gallstones, and the results of the hepatobiliary nuclear scan study (HIDA) were unremarkable. Magnetic resonance cholangiopancreatography (MRCP) revealed an intact intrahepatic and extrahepatic biliary tree and confirmed the presence of multiple lakes of bile ascites. During the entire hospital stay, the patient remained stable without any unifying diagnosis and she was discharged with a pigtail catheter. A follow-up abdominal CT scan revealed a complete resolution of the bilomas. We consider this as a spontaneous extra- and intrahepatic biloma of unknown etiology and should be in our differentials when a patient presents with right upper quadrant abdominal pain.

Ultrasonography enables the examiner to detect very small amounts of fluid in the peritoneal cavity and to determine its location, amount, and sonographic features. The pathologic process responsible for the ascites, for example, ileus, hepatic fibrosis, thrombosis of the caudal vena cava, or traumatic reticuloperitonitis, often can be identified. Abdominocentesis and analysis of the aspirated fluid allow differentiation of inflammatory and noninflammatory ascites as well as the diagnosis of uroperitoneum, hemoperitoneum, chylous ascites, and bile peritonitis.

Spontaneous or idiopathic biliary perforations are an infrequently encountered but an important cause of surgical jaundice in paediatric patients and one of the most common causes of surgical jaundice in infancy. A pre-operative diagnosis with a clinical history and physical findings may not be possible in most of the cases. The exact cause of the perforation remains unclear and the diagnosis is made at the time of laparotomy for an acute abdomen. An early, efficient and an effective surgical management is associated with a good prognosis; however, a delay in the correct diagnosis or an inappropriate management may result in bacterial contamination of the biliary ascites, with an unfavourable outcome. The relative rarity of this condition is reflected by the very few case reports, limited case studies and scarcity of published literature.
