RESUMO
A geriatric female giant panda developed grave signs of illness and was diagnosed with suspected hepatobiliary tract obstruction or other severe hepatic disease such as advanced cholangiohepatitis. The giant panda was euthanized and post mortem computed tomography was performed prior to necropsy. Common bile duct obstruction at the major duodenal papilla by a mineral attenuating calculus causing dilatation of common bile and gallbladder with concurrent multiple areas of liver abscess were detected by postmortem computed tomography. These were confirmed with gross necropsy. This is the first case report of common bile duct obstruction by mineral calculus with concurrent severe cholangiohepatitis in a giant panda.

BACKGROUND AND STUDY AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for the treatment of biliary obstruction of any etiology. However, cannulation failure of the common bile duct (CBD) by ERCP occurs in 5-10%. Alternatives after a failed ERCP are re-ERCP by an expert endoscopist, percutaneous transhepatic cholangio drainage (PTCD), (balloon) enteroscopy-assisted ERCP, or surgery. Endoscopic ultrasonography-guided drainage of the bile ducts (EUS-BD) is becoming the standard of care in tertiary referral centers for cases of failed ERCP in patients with malignant obstruction of the CBD. In expert hands, EUS-guided biliary drainage has excellent technical/clinical success rates and lower complication rates compared to PTCD. Despite the successful performance of EUS-BD in malignant cases, its use in benign cases is limited. The aim of this study (design, systematic prospective clinical observational study on quality assurance in daily clinical practice) was to evaluate the efficacy and safety of EUS-BD in benign indications. PATIENTS AND METHODS: Patients with cholestasis and failed ERCP were recruited from a prospective EUS-BD registry (2004-2020). One hundred and three patients with EUS-BD and benign cholestasis were extracted from the registry (nTotal = 474). Indications of EUS-BDs included surgically altered anatomy (n = 65), atypical bile duct percutaneous transhepatic cholangio orifice at the duodenal junction from the longitudinal to the horizontal segment (n = 1), papilla of Vater not reached due to the gastric outlet/duodenal stenoses (n = 6), papilla that cannot be catheterized (n = 24), and proximal bile duct stenosis (n = 7). The primary endpoint was technical and clinical success. Secondary endpoints were procedure-related complications during the hospital stay. RESULTS: 103 patients with EUS-BD and benign cholestasis were extracted from the registry (nTotal=474). Different transluminal access routes were used to reach the bile ducts: transgastric (n = 72/103); -duodenal (n = 16/103); -jejunal (n = 14/103); combined -duodenal and -gastric (n = 1/103). The technical success rate was 96 % (n = 99) for cholangiography. Drainage was not required in 2 patients; balloon dilatation including stone extraction was sufficient in 17 cases (16.5 %; no additional or prophylactic insertion of a drain). Transluminal drainage was achieved in n = 68/103 (66 %; even higher in patients with drain indication only) by placement of a plastic stent (n = 29), conventional biliary metal stents (n = 24), HotAXIOS stents (n = 5; Boston Scientific, Ratingen, Germany), Hanaro stents (n = 6; Olympus, Hamburg, Germany), HotAXIOS stents and plastic stents (n = 1), HotAXIOS stents and metal stents (n = 1) and metal stents and plastic stents (n = 2). Techniques for stone extraction alone (nSuccessful=17) or stent insertion (nTotal = 85; nSuccessful=85 - rate, 100 %) and final EUS-BD access pathway included: Rendezvous technique (n = 14/85; 16.5 %), antegrade internal drainage (n = 20/85; 23.5 %), choledochointestinostomy (n = 7/85; 8.2 %), antegrade internal and hepaticointestinostomy (n = 22/85; 25.9 %), hepaticointestinostomy (n = 21/85; 24.7 %), choledochointestinostomy and hepaticointestinostomy (n = 1/85; 1.2 %).The complication rate was 25 % (n = 26) - the spectrum comprised stent dislocation (n = 11), perforation (n = 1), pain (n = 2), hemorrhage (n = 6), biliary ascites/leakage (n = 3) and bilioma/liver abscess (n = 3; major complication rate, n = 12/68 - 17.6 %). Re-interventions were required in 19 patients (24 interventions in total). DISCUSSION: EUS-BD can be considered an elegant and safe alternative to PTCD or reoperation for failed ERCP to achieve the necessary drainage of the biliary system even in underlying benign diseases. An interventional EUS-based internal procedure can resolve cholestasis, avoid PTCD or reoperation, and thus improve quality of life. Due to the often complex (pathological and/or postoperative) anatomy, EUS-BD should only be performed in centers with interventional endoscopy/EUS experience including adequate abdominal surgery and interventional radiology expertise in the background. This enables adequately adapted therapeutic management in the event of challenging complications. It seems appropriate to conduct further studies with larger numbers of cases to systematize the approach and peri-interventional management and to successively develop specific equipment.

PURPOSE: We evaluated the safety and efficacy of transhepatic tract embolisation after a biliary intervention using n-butyl cyanoacrylate (NBCA) and autologous blood. MATERIALS AND METHODS: Between January 2017 and December 2018, 42 consecutive patients (mean age: 71 ± 15 years, 24 men) with malignant (n = 26) or benign (n = 16) biliary obstructions underwent percutaneous biliary intervention followed by tract embolisation within 2 weeks. Forty-six transhepatic tracts (4 bilateral) in 42 patients were embolised using a NBCA and lipiodol mixtures (1:1-1:2 ratios) after intraductal infusion of peripherally obtained autologous blood. The indwelling catheter diameters were 8.5-14 Fr. The median interval between percutaneous biliary drainage and tract embolisation was 10 days (range 3-14 days). Glue-cast formation via fluoroscopy and immediate complications were reviewed retrospectively in medical records. Follow-up data (median: 135, range 11-720 days) including computed tomography (CT) images (n = 17) were evaluated for delayed complications and glue-cast formation. RESULTS: Successful glue-cast formations were achieved in all 46 tracts. No patients experienced haemorrhage, and only one patient had external bile leakage. Eight patients complained of abdominal pain (numerical scale ≤ 5) immediately after embolisation, which was controlled by analgesics. Two patients had transient fever. Segmental (n = 11) or sub-segmental (n = 6) glue-cast patterns were identified along the transhepatic tract by follow-up CT. No biliary obstructions were caused by inadvertent glue spread. Fragmented glue was detected outside the stent in one patient. CONCLUSION: Transhepatic parenchymal tract embolisation with NBCA and autologous blood is a safe and feasible method for preventing bile leakage. LEVEL OF EVIDENCE: Level 4, Case Series.

BACKGROUND: The use of prophylactic antibiotics before endoscopic retrograde cholangiopancreatography (ERCP) is recommended by all major international gastroenterological societies, especially in the presence of an obstructed biliary system. This study compared the occurrence rate of post-procedural complications, including cholangitis and septicemia, between prophylactic intravenous moxifloxacin and ceftriaxone in patients with bile duct obstruction scheduled for therapeutic ERCP. METHODS: From November 2013 to July 2015, 86 consecutive patients with biliary obstruction with one or more factors predicting benefits of antibiotic prophylaxis prior to ERCP were included in the current randomized open-label non-inferiority trial (ClinicalTrial.gov identifier NCT02098486). Intravenous moxifloxacin (400 mg/day) or ceftriaxone (2 g/day) were given 90 minutes before ERCP, and were administered for more than 3 days if the patient developed symptoms and signs of cholangitis or septicemia. Recalcitrant cholangitis was defined as persistence of cholangitis for more than 5 days after ERCP or recurrence of cholangitis within 30 days after ERCP. RESULTS: Recalcitrant cholangitis occurred in 1 (2.3%) and 2 (4.8%) patients receiving intravenous moxifloxacin and ceftriaxone group, respectively (P=0.612). Septicemia was noted in 1 (2.3%) and 1 (2.4%) patient in intravenous moxifloxacin and ceftriaxone group, respectively (P=1.0). The mean hospital stay was also not significantly different between the moxifloxacin and ceftriaxone groups (8.8±7.2 vs 9.1±9.4 days, P=0.867). Antibiotic resistance of the isolated pathogens by in vitro activity assay was noted in 1 (2.3%) and 2 (4.8%) patients in the moxifloxacin and ceftriaxone group, respectively (P=0.612). CONCLUSION: Intravenous moxifloxacin is not inferior to intravenous ceftriaxone for the prophylactic treatment of post-ERCP cholangitis and cholangitis-associated morbidity.

BACKGROUND: Patients with failed endoscopic retrograde cholangiopancreatography (ERCP) are conventionally offered percutaneous transhepatic biliary drainage (PTBD). While PTBD is effective, it is associated with catheter-related complications, pain, and poor quality of life. Endoscopic ultrasound-guided biliary drainage (EUS-BD) is a minimally invasive endoscopic option increasingly offered as an alternative to PTBD. We compare outcomes of EUS-BD and PTBD in patients with biliary obstruction at a single tertiary care center. METHODS: A retrospective review was performed in patients with biliary obstruction who underwent EUS-BD or PTBD after failed ERCP from June 2010 through December 2014 at a single tertiary care center. Patient demographics, procedural data, and clinical outcomes were documented for each group. The aim was to compare efficacy and safety of EUS-BD and PTBD and evaluate predictors of success. RESULTS: A total of 60 patients were included (mean age 67.5 years, 65 % male). Forty-seven underwent EUS-BD, and thirteen underwent PTBD. Technical success rates of PTBD and EUS-BD were similar (91.6 vs. 93.3 %, p = 1.0). PTBD patients underwent significantly more re-interventions than EUS-BD patients (mean 4.9 versus 1.3, p < 0.0001), had more late (>24-h) adverse events (53.8 % vs. 6.6 %, p = 0.001) and experienced more pain (4.1 vs. 1.9, p = 0.016) post-procedure. In univariate analysis, clinical success was lower in the PTBD group (25 vs. 62.2 %, p = 0.03). In multivariable logistic regression analysis, EUS-BD was the sole predictor of clinical success and long-term resolution (OR 21.8, p = 0.009). CONCLUSION: Despite similar technical success rates compared to PTBD, EUS-BD results in a lower need for re-intervention, decreased rate of late adverse events, and lower pain scores, and is the sole predictor for clinical success and long-term resolution. EUS-BD should be the treatment of choice after a failed ERCP.

BACKGROUND: EUS-guided biliary drainage (EUS-BD) may be a feasible and useful alternative in patients with malignant biliary obstruction after failed ERCP. One of the main limitations of EUS-BD is the lack of devices specifically tailored to this technique. OBJECTIVE: To evaluate a newly developed hybrid metal stent customized for EUS-BD. DESIGN: A prospective, observational study. SETTING: A tertiary academic referral center. PATIENTS: A total of 27 consecutive patients with malignant biliary obstruction who were candidates for alternative techniques for biliary drainage because of failed ERCP were enrolled. INTERVENTIONS: EUS-BD with a newly developed hybrid metal stent. MAIN OUTCOME MEASUREMENTS: The technical and clinical success rates and adverse events, including proximal or distal stent migration and cholangitis. RESULTS: EUS-guided hepaticogastrostomy was performed in 10 patients, and EUS-guided choledochoduodenostomy was performed in 17 patients. The technical success rate of EUS-BD with the hybrid metal stent was 100% (27/27), and clinical success was achieved in 96.3% (26/27) of the cases. Adverse events developed in 5 patients (5/27, 18.5%), including a self-limited pneumoperitoneum in 3 patients, minor bleeding in 1 patient, and abdominal pain in 1 patient. During the follow-up period (median 134 days), proximal or distal stent migration was not observed. LIMITATIONS: This study was performed at a single center by a single experienced operator with a relatively small number of patients. CONCLUSION: EUS-BD with a hybrid metal stent is technically feasible and can be an effective treatment for malignant biliary obstruction after failed ERCP. Hybrid metal stents may be used safely in EUS-BD, and they can prevent stent-related adverse events.

OBJECTIVE: Parenteral nutrition-associated cholestasis (PNAC) occurs in up to 60% of surgical neonates with intestinal failure, and 10% will develop end-stage liver failure. Our aim was to evaluate the effectiveness of percutaneous transhepatic transcholecystic cholangiography (PTTC) in the treatment of PNAC in surgical neonates. METHODS: A retrospective double cohort study of surgical neonates with PNAC was conducted. Patients with PNAC who received PTTC were compared to controls matched by gestational age, birth weight, sex, and parenteral nutrition duration. Percutaneous transhepatic transcholecystic cholangiography was performed under general anesthesia with ultrasound guidance. Analysis was performed using paired Student's t test and McNemar chi2 test. RESULTS: Nine PTTC patients and 9 controls were similar in mean age (35.5 +/- 3.1 vs 35.6 +/- 4.2 weeks, P = .85), birth weight (2531 +/- 879 vs 2692 +/- 1052 g, P = .28), sex (all males), and parenteral nutrition duration (51.2 +/- 29.8 vs 53.3 +/- 33.3 days, P = .74). Percutaneous transhepatic transcholecystic cholangiography was performed in 9 patients at mean corrected age of 5.5 +/- 3.4 weeks and weight of 3621 +/- 546 g. All control patients and 8 (88.9%) of 9 PTTC patients had eventual resolution of hyperbilirubinemia. Percutaneous transhepatic transcholecystic cholangiography patients experienced a more rapid rate of resolution of their cholestasis, and the mean time to resolution of conjugated bilirubin was less in the PTTC group (8.5 +/- 3.2 vs 18.5 +/- 7.6 weeks, P = .02). CONCLUSION: Therapeutic PTTC results in a 50% reduction in the time to PNAC resolution. Percutaneous transhepatic transcholecystic cholangiography may have a role as active therapy to slow progression of PNAC in surgical neonates with intestinal failure.

Cholescintigraphy after food stimulation was carried out in 40 patients (13 patients with biliary enteric bypass, 14 patients with bile duct stenosis, demonstrated by ERC, 5 patients with endoprothesis and 8 patients with clinically suspected post-cholecystectomy syndrome. Biliary-bowel transit time of one hour or less was considered to be normal. In patients with biliary enteric bypass 11 had a normal transit time; however, one with a concomitant anastomotic leakage, and 2 patients had prolonged transit time and a significant obstruction by the anastomosis. All 14 patients with demonstrated biliary stricture had normal transit time. In 5 patients with endoprothesis, 2 had prolonged transit time in spite of patent endoprothesis. Finally, in the 8 patients with suspected post-cholecystectomy syndrome, 4 had normal sphincter of Oddi manometry and normal transit time, and 4 had abnormal sphincter of Oddi manometry, but only one with prolonged transit time. It is concluded that in patients with biliary enteric bypass (hepatico-jejunostomia) or biliary strictures a biliary-bowel transit time of one hour will be discriminatory between normal and abnormal conditions. This is in contrast to patients with endoprothesis and suspected sphincter of Oddi dysmotility, where a transit time of one hour only will have limited predictive value.

The utility of 99mTc-IDA imaging in the differential diagnosis of jaundice was assessed. Although overall accuracy was 84%, this method is still inferior to the reported efficiency of ultrasonography and CT in making the correct diagnosis. Radionuclide imaging is a good alternative when these other modalities are not available and it functions well in an adjuvant capacity. The diagnostic limitations of 99mTc-dimethyl IDA imaging in cases of moderate to severe jaundice are largely overcome by the use of 99mTc-p-butyl IDA.
