Gallbladder perforation with formation of hepatic subcapsular biloma, treated with endoscopic nasobiliary drainage

Large biloma as the initial presentation of gallbladder perforation: a case report and literature review

Biloma is an encapsulated intra or extra-hepatic collection of bile after biliary tree trauma. Post-procedural and traumatic biliary damage are the most common etiologic causes. Gallbladder perforation due to acute cholecystitis rarely presents with biloma occurrence. We present a case of large extrahepatic biloma formation as a consequence of a perforated gallbladder.

Massive hemoperitoneum and upper gastrointestinal hemorrhage following liver rupture secondary to gallbladder perforation: A case report and literature review

RATIONALE

Available literature states that the common reasons for non-traumatic spontaneous liver rupture are hepatocellular carcinoma, macronodular cirrhosis, hemangioma, and other tumors; gallbladder perforation is not cited as a cause.

PATIENT CONCERNS

The patient presented with sudden-onset right upper quadrant pain with tarry stool for 3 days after eating with dysphoria and increasing thirst; gradually, hemorrhagic shock developed. He had no history of trauma, no background of chronic hepatitis, and no cirrhosis.

DIAGNOSIS

Hemorrhage secondary to spontaneous rupture of intrahepatic cholangiocarcinoma.

INTERVENTIONS

Left hemihepatectomy, cholecystectomy, and common bile duct exploration were performed.

OUTCOMES

The patient was diagnosed with massive hemoperitoneum accompanying upper gastrointestinal hemorrhage following liver rupture secondary to gallbladder perforation. The postoperative course was uneventful and the patient was discharged after 10 days of hospitalization.

LESSONS

If patients present with non-traumatic spontaneous liver rapture accompanying cholelithiasis and gallbladder hematoma, gallbladder perforation should be considered as a differential diagnosis. Misdiagnosis can lead to incorrect treatment.

A giant and insidious subphrenic biloma formation due to gallbladder perforation mimicking biliary cystic tumor: A case report

Gallbladder perforation (GBP) represents a rare, but potentially life-threatening, complication of acute cholecystitis. GBP is subdivided into three categories whereas the development of biloma is extremely rare. The present case study reports on a 40-year-old man with a 10-year history of calculus cholecystitis, who was referred to The First Affiliated Hospital of Nanjing Medical University (Nanjing, China) for the surgical treatment of an emerging massive hepatic entity with insidious symptoms and normal laboratory tests. A preoperative imaging study demonstrated the collection with internal septations and mural nodules, but no visible communication with the biliary system. Given the suspected biliary cystic tumor, a laparotomy was performed and the lumen was scattered with papillae. An intraoperative frozen section examination illustrated a simple hepatic cyst. Biochemical analysis of the collection and histopathology of the gallbladder and capsule substantiated the diagnosis of biloma formation due to GBP. The purpose of the present case report was to demonstrate how a pinhole-sized perforation with extravasation of unconcentrated bile from the gallbladder may result in insidious clinical presentation and an undetected leak site. According to the clinicopathological characteristics and composition, formation of biloma should be classified as type IV GBP. To differentiate bilomas with intracystic septations and mural nodules from BCTs is difficult via a preoperative examination, and the definitive diagnosis should be based on a histological examination. Laparotomy with frozen section examination may be the optimal approach in such a case.

Nasoenteric Tube Complications

The use of nasoenteric tubes (NETs) is ubiquitous, and clinicians often take their placement, function, and maintenance for granted. NETs are used for gastrointestinal decompression, enteral feeding, medication administration, naso-biliary drainage, and specialized indications such as upper gastrointestinal bleeding. Morbidity associated with NETETs is common, but frequently subtle, mandating high index of suspicion, clinical vigilance, and patient safety protocols. Common complications include sinusitis, sore throat and epistaxis. More serious complications include luminal perforation, pulmonary injury, aspiration, and intracranial placement. Frequent monitoring and continual re-review of the indications for continued use of any NETET is prudent, including consideration of changing goals of care. This manuscript reviews NET-related complications and associated topics.
