Project description:Background and study aims White bile is defined as a colorless fluid occasionally found in the biliary tract of patients with bile duct obstruction. Its significance is not clearly established. Our objective was to analyze the prognostic value of white bile in a series of patients with biliary obstruction due to biliary or pancreatic cancer. Patients and methods The study was conducted on a series of consecutive patients with malignant obstructive jaundice. They all underwent endoscopic retrograde cholangiopancreatography with collection of bile and biliary stent insertion. White bile was defined as bile duct fluid with bilirubin level < 20 µmol/L. Univariate and multivariate analyses were performed to identify variables associated with overall survival (OS). Results Seventy-three patients were included (32 pancreatic cancers, 41 bile duct cancers). Thirty-nine (53.4 %) had white bile. The mean bile duct bilirubin level in this group was 4.2 ± 5.9 µmol/L vs 991 ± 1039 µmol/L in patients with colored bile (P < 0.0001). In the group of 54 patients not eligible for surgery, the multivariate analysis demonstrated an association between the presence of white bile and reduced OS (HR 2.3, 95 %CI 1.1-4.7; P = 0.02). Other factors independently associated with OS were metastatic extension (HR 2.8, 95 %CI 1.4-5.7) and serum total bilirubin (HR 1.003, 95 %CI 1.001-1.006). There was a significant inverse correlation between serum and bile duct bilirubin levels (r = -0.43, P = 0.0001). Conclusion White bile in patients with inoperable malignant biliary obstruction is an independent factor of poor survival.

Project description:ObjectivesTo compare the use of an antireflux metal stent (ARMS) with that of a conventional covered self-expandable metal stent (c-CSEMS) for initial stenting of malignant distal biliary obstruction (MDBO).Materials and methodsWe retrospectively investigated 59 consecutive patients with unresectable MDBO undergoing initial endoscopic biliary drainage. ARMS was used in 32 patients and c-CSEMS in 27. Technical success, functional success, complications, causes of recurrent biliary obstruction (RBO), time to RBO (TRBO), and reintervention were compared between the groups.ResultsStent placement was technically successful in all patients. There were no significant intergroup differences in functional success (ARMS [96.9%] versus c-CSEMS [96.2%]), complications (6.2 versus 7.4%), and RBO (48.4 versus 42.3%). Food impaction was significantly less frequent for ARMS than for c-CSEMS (P = 0.037), but TRBO did not differ significantly between the groups (log-rank test, P = 0.967). The median TRBO was 180.0 [interquartile range (IQR), 114.0-349.0] days for ARMS and 137.0 [IQR, 87.0-442.0] days for c-CSEMS. In both groups, reintervention for RBO was successfully completed in all patients thus treated.ConclusionARMS offers no advantage for initial stent placement, but food impaction is significantly prevented by the antireflux valve.

Project description:BACKGROUND AND OBJECTIVES:Endoscopic retrograde cholangiopancreatography (ERCP) is the method of choice for drainage in patients with distal malignant biliary obstruction, but it fails in up to 10% of cases. Percutaneous transhepatic cholangiography (PTC) and surgical bypass are the traditional drainage alternatives. This study aimed to compare technical and clinical success, quality of life, and survival of surgical biliary bypass or hepaticojejunostomy (HJT) and endoscopic ultrasound (EUS)-guided choledochoduodenostomy (CDT) in patients with distal malignant bile duct obstruction and failed ERCP. PATIENTS AND METHODS:A prospective, randomized trial was conducted. From March 2011 to September 2013, 32 patients with malignant distal biliary obstruction and failed ERCP were studied. The HJT group consisted of 15 patients and the CDT group consisted of 14 patients. Technical and clinical success, quality of life, and survival were assessed prospectively. RESULTS:Technical success was 94% (15/16) in the HJT group and 88% (14/16) in the CDT group (P = 0.598). Clinical success occurred in 14 (93%) patients in the HJT group and in 10 (71%) patients in the CDT group (P = 0.169). During follow-up, a statistically significant difference was seen in mean functional capacity scores, physical health, pain, social functioning, and emotional and mental health aspects in both techniques (P < 0.05). The median survival time in both groups was the same (82 days). CONCLUSION:Data relating to technical and clinical success, quality of life, and survival were similar in patients who underwent HJT and CDT drainage after failed ERCP for malignant distal biliary obstruction.

Project description:Background and aimsStent migration is one of the most common complications during the placement of multiple plastic biliary stents (MPBS) under endoscopy. This study aims to evaluate the feasibility and efficiency of the fishing line assisted (FLA) method for preventing the complication.MethodsPatients with unresectable malignant hilar biliary obstruction (MHBO) who undergone endoscopic placement of MPBS using the FLA or conventional method from May 2018 to April 2021 in our center were enrolled in the study. The endpoints of this study were the stent migration rate, technical success rates, adverse events rates, times of stent migration, and the procedure time.ResultsFLA group (N = 19) and conventional group (N = 22) had similar baseline characteristics of the patients. The technical success rates (100% vs. 95.5%; P > 0.05), ERCP-related adverse events rates (5.3% vs. 4.5%; P > 0.05), and the stent-related adverse events rates (0% vs. 4.5%; P > 0.05) were no significant differences between the FLA and conventional groups. MPBS inserted using the conventional method consumed more time (median, 33.9 min vs. 15.6 min; P < 0.05) method and increased the times of stent migration (median, 3 times vs. 0 times; P < 0.05) than using the FLA method. Even if no statistical difference was detected in the stent migration rate between groups, this rate was lower in the FLA group than the conventional group (0% vs. 13.6%; P > 0.05).ConclusionsFLA method is an effective technique for MPBS implantation to prevent stent migration during endoscopic retrograde cholangiography (ERCP). The method should be applied to patients with unresectable MHBO who need to place MPBS.

Project description:BackgroundThe treatments for cancer palliation in patients with concomitant malignant biliary obstruction (MBO) and gastric outlet obstruction (MGOO) are still under investigation due to the lack of evidence available in the medical literature. We performed a systematic search and critical review to investigate efficacy and safety among patients with MBO and MGOO undergoing both endoscopic ultrasound-guided biliary drainage (EUS-BD) and MGOO endoscopic treatment.MethodsA systematic literature search was performed in PubMed, MEDLINE, EMBASE, and the Cochrane Library. EUS-BD included both transduodenal and transgastric techniques. Treatment of MGOO included duodenal stenting or EUS-GEA (gastroenteroanastomosis). Outcomes of interest were technical success, clinical success, and rate of adverse events (AEs) in patients undergoing double treatment in the same session or within one week.Results11 studies were included in the systematic review for a total number of 337 patients, 150 of whom had concurrent MBO and MGOO treatment, fulfilling the time criteria. MGOO was treated by duodenal stenting (self-expandable metal stents) in 10 studies, and in one study by EUS-GEA. EUS-BD had a mean technical success of 96.4% (CI 95%, 92.18-98.99) and a mean clinical success of 84.96% (CI 95%, 67.99-96.26). The average frequency of AEs for EUS-BD was 28.73% (CI 95%, 9.12-48.33). Clinical success for duodenal stenting was 90% vs. 100% for EUS-GEA.ConclusionsEUS-BD could become the preferred drainage in the case of double endoscopic treatment of concomitant MBO and MGOO in the near future, with the promising EUS-GEA becoming a valid option for MGOO treatment in these patients.

Project description:Background/aimsEndoscopic ultrasound (EUS)-guided hepaticogastrostomy (EUS-HGS) is useful for patients with biliary cannulation failure or inaccessible papillae. However, it can lead to serious complications such as bile peritonitis in patients with ascites; therefore, development of a safe method to perform EUS-HGS is important. Herein, we evaluated the safety of EUS-HGS with continuous ascitic fluid drainage in patients with ascites.MethodsPatients with moderate or severe ascites who underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after the procedure at our institution between April 2015 and December 2022, were included in the study. We evaluated the technical and clinical success rates, EUS-HGS-related complications, and feasibility of re-intervention.ResultsTen patients underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after completion of the procedure. Median duration of ascites drainage before and after EUS-HGS was 2 and 4 days, respectively. Technical success with EUS-HGS was achieved in all 10 patients (100%). Clinical success with EUS-HGS was achieved in 9 of the 10 patients (90 %). No endoscopic complications such as bile peritonitis were observed.ConclusionIn patients with ascites, continuous ascites drainage, which is initiated before EUS-HGS and terminated after completion of the procedure, may prevent complications and allow safe performance of EUS-HGS.
