Pseudoaneurysms of the cystic artery and cholecystoduodenal fistula formation are rare complications of cholecystitis and either may result from an inflammatory process in the abdomen. A 68-year-old man admitted with acute cholecystitis subsequently developed massive upper gastrointestinal (GI) bleeding. Abdominal computed tomography showed acute calculous cholecystitis and hemobilia secondary to bleeding from the cystic artery. Angiography suggested a ruptured pseudoaneurysm of the cystic artery. Upper GI endoscopy showed a deep active ulcer with an opening that was suspected to be that of a fistula at the duodenal bulb. The patient was managed successfully with multimodality treatment that included embolization followed by elective laparoscopic cholecystectomy. Presently, there is no clear consensus regarding the clinical management of this disease. We have been able to confirm various clinical features, diagnoses, and treatments of this disease through a literature review. A multidisciplinary approach through interagency/interdepartmental collaboration is necessary for better management of this disease.

OBJECTIVE: To investigate the technical safety and clinical efficacy of a double-stent system with long duodenal extension in patients with malignant extrahepatic biliary obstruction. MATERIALS AND METHODS: This prospective study enrolled 48 consecutive patients (31 men, 17 women; mean age, 61 years; age range, 31–77 years) with malignant extrahepatic biliary obstructions from May 2013 to December 2015. All patients were treated with a double-stent system with long duodenal covered extension (16 cm or 21 cm). RESULTS: The stents were successfully placed in all 48 patients. There were five (10.4%) procedure-related complications. Minor complications were self-limiting hemobilia (n = 2). Major complications included acute pancreatitis (n = 1) and acute cholecystitis (n = 2). Successful internal drainage was achieved in 42 (87.5%) patients. Median patient survival and stent patency times were 92 days (95% confidence interval [CI], 61–123 days) and 83 days (95% CI, 46–120 days), respectively. Ten (23.8%) of the 42 patients presented with stent occlusion due to food impaction with biliary sludge, and required repeat intervention. Stent occlusion was more frequent in metastatic gastric cancer patients with pervious gastrectomy, but did not reach statistical significance (p = 0.069). CONCLUSION: Percutaneous placement of a double-stent system with long duodenal extension is feasible and safe. However, this stent system does not completely prevent stent occlusion caused by food reflux.

OBJECTIVE: To investigate the outcomes of percutaneous metallic stent placements in patients with malignant biliary hilar obstruction (MBHO). MATERIALS AND METHODS: From January 2007 to December 2014, 415 patients (mean age, 65 years; 261 men [62.8%]) with MBHO were retrospectively studied. All the patients underwent unilateral or bilateral stenting in a T, Y, or crisscross configuration utilizing covered or uncovered stents. The clinical outcomes evaluated were technical and clinical success, complications, overall survival rates, and stent occlusion-free survival. RESULTS: A total of 784 stents were successfully placed in 415 patients. Fifty-five patients had complications. These complications included hemobilia (n = 19), cholangitis (n = 13), cholecystitis (n = 11), bilomas (n = 10), peritonitis (n = 1), and hepatic vein-biliary fistula (n = 1). Clinical success was achieved in 370 patients (89.1%). Ninety-seven patients were lost to follow-up. Stent dysfunction due to tumor ingrowth (n = 107), sludge incrustation (n = 44), and other causes (n = 3) occurred in 154 of 318 patients. The median overall survival and the stent occlusion-free survival were 212 days (95% confidence interval [CI], 186−237 days) and 141 days (95% CI, 126−156 days), respectively. The stent type and its configuration did not affect technical success, complications, successful internal drainage, overall survival, or stent occlusion-free survival. CONCLUSION: Percutaneous stent placement may be safe and effective for internal drainage in patients with MBHO. Furthermore, stent type and configuration may not significantly affect clinical outcomes.

A 75-year-old man with chronic cholangitis and a common bile duct stone that was not previously identified was admitted for right upper quadrant pain. Acute cholecystitis with cholangitis was suspected on abdominal computed tomography (CT); therefore, endoscopic retrograde cholangiopancreatography with endonasal biliary drainage was performed. On admission day 5, hemobilia with rupture of two intrahepatic artery pseudoaneurysms was observed on follow-up abdominal CT. Coil embolization of the pseudoaneurysms was conducted using percutaneous transhepatic biliary drainage. After several days, intrahepatic artery pseudoaneurysm rupture recurred and coil embolization through a percutaneous transhepatic biliary drainage tract was conducted after failure of embolization via the hepatic artery due to previous coiling. After the second coil embolization, a common bile duct stone was removed, and the patient presented no complications during 4 months of follow-up. We report a case of intrahepatic artery pseudoaneurysm rupture without prior history of intervention involving the hepatobiliary system that was successfully managed using coil embolization through percutaneous transhepatic biliary drainage.

SUMMARY OF EVENT: Melena with abdominal pain were developed in a patient who had undergone endoscopic retrograde cholangiopancreatography (ERCP) with common bile duct stones removal and endoscopic retrograde biliary drainage (ERBD) using a plastic biliary stent. He subsequently underwent laparoscopic cholecystectomy. For the diagnosis and treatment of hemobilia caused by a plastic biliary stent, selective angiography for gastroduodenal artery with subsequent embolization for small pseudoaneurysm of pancreaticoduodenal artery was done successfully. TEACHING POINT: A plastic biliary stent induced pseudoaneurysm can be a cause of hemobilia after ERCP with ERBD procedure. Selective angiography with embolization for bleeding pseudoaneurysm can be an effective treatment for this situation.

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential method for diagnosis and treatment of various pancreatobiliary diseases and endoscopic sphincterotomy (EST) is the gateway to complete ERCP. Although techniques and instruments for EST have improved, bleeding is still the most common complication. Treatment of immediate post-EST bleeding is important because blood can interfere with subsequent procedures. Additionally, endoscopists should be cautious about delayed bleeding may cause hemobilia, cholangitis, and hemodynamic shock. Most cases of post-EST bleedings will stop spontaneously, however, endoscopic management is necessary in case of clinically significant and persistent bleeding. Various endoscopic methods including epinephrine or fibrin glue injection, electrocoagulation, hemoclipping and band ligation et al can be used through a sideviewing or forward-viewing endoscope similar to those used in hemostasis of peptic ulcer bleeding. Endoscopists who perform ERCP should use various methods of endoscopic hemostasis strategically.

Biliary complications are the most common post-liver transplant (LT) complications with an incidence of 15%–45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT compared to a deceased-donor LT. Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%. In this regard, conventional endoscopic retrograde cholangiopancreatography remains the preferred initial treatment. However, percutaneous transhepatic cholangioscopy is now central to the management of endoscopy-resistant cases involving complex hilar or multiple strictures with associated stones. Many additional endoscopic tools and techniques—such as the rendezvous method, magnetic compression anastomosis , and peroral cholangioscopy—combined with modified biliary stents have significantly improved the success rate of endoscopic management. Here, we review the current status of endoscopic treatment of post-LT biliary complications and discuss conventional as well as the aforementioned new tools and techniques.

Hemobilia is a rare gastrointestinal bleeding, usually caused by injury to the bile duct. Hemobilia after endoscopic retrograde cholangiopancreatography (ERCP) is generally self-limiting and patients will spontaneously recover, but some severe and fatal hemorrhages have been reported. ERCP-related bowel or bile duct perforation should be managed promptly, according to the type of injury and the status of the patient. We recently experienced a case of late-onset severe hemobilia in which the patient recovered after endoscopic biliary stent insertion. The problem was attributable to ERCP-related bile duct perforation during stone removal, approximately 5 weeks prior to the hemorrhagic episode. The removal of the stent was performed 10 days before the onset of hemobilia. The bleeding was successfully treated by two sessions of transarterial coil embolization.

Anticoagulation therapy is essential after cardiac valve surgery. However, spontaneous bleeding remains a major concern during anticoagulation therapy. Spontaneous gallbladder (GB) hemorrhage (hemobilia) is a rare occurrence during standard anticoagulation therapy. This report presents a case of GB hemorrhage that occurred shortly after initiating oral anticoagulant therapy in a patient who had undergone mitral valve replacement surgery.
