AI Article Synopsis
- Hemobilia, which can occur after laparoscopic cholecystectomy (LC), presents diagnostic and treatment challenges, and this study evaluates the role of CT imaging and transcatheter arterial embolization (TAE) in such cases.
- Fourteen patients with hemobilia were studied, with diagnoses made via endoscopy for 3 patients and contrast-enhanced CT for 11; TAE involved precisely targeting and occluding the bleeding vessel.
- CT findings included indicators like hematomas and blood clots, and TAE had a 100% success rate without rebleeding, though some patients experienced complications linked to age and timing of the procedures.*
Article Abstract
Background: Hemobilia following laparoscopic cholecystectomy (LC) can occur in the early or late postoperative course and poses a diagnostic and therapeutic challenge.
Purpose: To assess computed tomography (CT) findings and clinical outcomes after transcatheter arterial embolization (TAE) in patients presenting with hemobilia following LC.
Material And Methods: Fourteen patients treated for hemobilia following LC were included in the study. Three patients were diagnosed by endoscopy and 11 by abdominal contrast-enhanced CT. Coils or microcoils were superselectively deployed to occlude the bleeding vessel during TAE. Abdominal CT findings of hemobilia, and the success rate and complication of TAE were observed.
Results: Abdominal CT provided the following signs of hemobilia: hematoma within the abdominal cavity and gallbladder fossa, blood clots containing high attenuation within the bile duct, biliary dilatation, pseudoaneurysm of the right hepatic artery, contrast extravasation, enhancement of the bile duct wall, and hypoperfusion of the right lobe. The success rate of TAE was 100% and rebleeding did not occur in any patient. Post-embolization syndrome and hepatic ischemia occurred in nine patients, which was associated with age and the time interval between the LC and TAE.
Conclusion: Abdominal CT provided direct signs that can aid in the diagnosis of hemobilia after LC. TAE allowed for successful treatment of hemobilia with minor complications.

Hemobilia is a relatively uncommon but important cause of gastrointestinal bleeding. It occurs due to abnormal communications between the biliary system and surrounding vasculature, often caused by surgical interventions, trauma, infections, or malignancies. The rise of advanced hepato-pancreato-biliary techniques, including radiofrequency ablation and transjugular intrahepatic portosystemic shunt (TIPS) placement, necessitates careful evaluation for the potential presence of hemobilia during the post-procedural period of these patients.

Recent clinical outcomes of multi-regimen chemotherapy in patients with cholangiocarcinoma (CCC) have shown benefits in terms of overall survival. However, repeated endoscopic biliary drainage (EBD) and serious adverse events negatively affect prolongation of the survival period. The aim of this study was to investigate the prevalence of massive hemobilia and the outcomes of its management with fully covered self-expandable metal stents (FC-SEMSs) in patients with hilum-involving CCC receiving multi-regimen chemotherapy.

Hemorrhagic cholecystitis (HC) is a rare complication that can become rapidly fatal. Patients may present with hematemesis or melena, in addition to other common symptoms of acute cholecystitis. Delay in diagnosing HC postpones early intervention, and patients can quickly decompensate.

- * A 64-year-old woman was treated for CAP after presenting with abdominal pain and gastrointestinal bleeding, with imaging confirming the diagnosis.
- * Successful management involved angioembolization followed by cholecystectomy, highlighting the need for early detection and intervention in cases of CAP associated with acute cholecystitis.

Objective: To evaluate and compare the efficacy and safety of Endoscopic Nasobiliary Drainage (ENBD) and Percutaneous Transhepatic Cholangiography Drainage (PTCD) in patients with advanced Hilar Cholangiocarcinoma (HCCA) through a meta-analysis of clinical studies.
Methods: We searched Chinese and English databases, including China National Knowledge Infrastructure (CNKI), Wanfang database, PubMed, Embase, Scopus, and Web of Science, for relevant literatures on PTCD and ENBD for advanced HCCA clinical trials. Two investigators independently screened the literatures, and the quality of the included studies was evaluated using the Newcastle-Ottawa Scale (NOS).
