Endoscopic Ultrasound-Guided Biliary Drainage of First Intent With a Lumen-Apposing Metal Stent vs Endoscopic Retrograde Cholangiopancreatography in Malignant Distal Biliary Obstruction: A Multicenter Randomized Controlled Study (ELEMENT Trial). Gastroenterology 2023; 165:1249-1261.e5. [PMID: 37549753 DOI: 10.1053/j.gastro.2023.07.024] [Citation(s) in RCA: 16] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 07/21/2023] [Accepted: 07/29/2023] [Indexed: 08/09/2023]
Abstract
BACKGROUND & AIMS Endoscopic ultrasound-guided choledochoduodenostomy with a lumen-apposing metal stent (EUS-CDS) is a promising modality for management of malignant distal biliary obstruction (MDBO) with potential for better stent patency. We compared its outcomes with endoscopic retrograde cholangiopancreatography with metal stenting (ERCP-M). METHODS In this multicenter randomized controlled trial, we recruited patients with MDBO secondary to borderline resectable, locally advanced, or unresectable peri-ampullary cancers across 10 Canadian institutions and 1 French institution. This was a superiority trial with a noninferiority assessment of technical success. Patients were randomized to EUS-CDS or ERCP-M. The primary end point was the rate of stent dysfunction at 1 year, considering competing risks of death, clinical failure, and surgical resection. Analyses were performed according to intention-to-treat principles. RESULTS From February 2019 to February 2022, 144 patients were recruited; 73 were randomized to EUS-CDS and 71 were randomized to ERCP-M. The mean (SD) procedure time was 14.0 (11.4) minutes for EUS-CDS and 23.1 (15.6) minutes for ERCP-M (P < .01); 40% of the former was performed without fluoroscopy. Technical success was achieved in 90.4% (95% CI, 81.5% to 95.3%) of EUS-CDS and 83.1% (95% CI, 72.7% to 90.1%) of ERCP-M with a risk difference of 7.3% (95% CI, -4.0% to 18.8%) indicating noninferiority. Stent dysfunction occurred in 9.6% vs 9.9% of EUS-CDS and ERCP-M cases, respectively (P = .96). No differences in adverse events, pancreaticoduodenectomy and oncologic outcomes, or quality of life were noted. CONCLUSIONS Although not superior in stent function, EUS-CDS is an efficient and safe alternative to ERCP-M in patients with MDBO. These findings provide evidence for greater adoption of EUS-CDS in clinical practice as a complementary and exchangeable first-line modality to ERCP in patients with MDBO.

EUS-guided biliary drainage in malignant distal biliary obstruction: An international survey to identify barriers of technology implementation. Endosc Ultrasound 2023; 12:104-110. [PMID: 36861509 PMCID: PMC10134941 DOI: 10.4103/eus-d-21-00137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 04/24/2022] [Indexed: 03/03/2023] Open
Abstract
Background and Objectives EUS-guided biliary drainage (EUS-BD) is a promising alternative to ERCP in malignant distal biliary obstruction (MDBO). Despite accumulating data, however, its application in clinical practice has been impeded by undefined barriers. This study aims to evaluate the practice of EUS-BD and its barriers. Methods An online survey was generated using Google Forms. Six gastroenterology/endoscopy associations were contacted between July 2019 and November 2019. Survey questions measured participant characteristics, EUS-BD in different clinical scenarios, and potential barriers. The primary outcome was the uptake of EUS-BD as a first-line modality, without previous ERCP attempts, in patients with MDBO. Results Overall, 115 respondents completed the survey (2.9% response rate). Respondents were from North America (39.2%), Asia (28.6%), Europe (20%), and other jurisdictions (12.2%). Regarding the uptake of EUS-BD as first-line treatment for MDBO, only 10.5% of respondents would consider EUS-BD as a first-line modality regularly. The main concerns were the lack of high-quality data, fear of adverse events, and limited access to EUS-BD dedicated devices. On multivariable analysis, lack of access to EUS-BD expertise was an independent predictor against the use of EUS-BD, odds ratio 0.16 (95% confidence interval, 0.04-0.65). In salvage situations following failed ERCP, most favored EUS-BD (40.9%) over percutaneous drainage (21.7%) in unresectable cancer. In borderline resectable or locally advanced disease, however, most favored the percutaneous approach due to fear of EUS-BD complicating future surgery. Conclusions EUS-BD has not reached widespread clinical adoption. Identified barriers include lack of high-quality data, fear of adverse events, and lack of access to EUS-BD dedicated devices. Fear of complicating future surgery was also identified as a barrier in potentially resectable disease.

Benign biliary strictures associated with acute biliary pancreatitis. Surg Endosc 2022; 37:2587-2594. [PMID: 36348167 DOI: 10.1007/s00464-022-09753-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 10/29/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND AND AIMS There are limited data about the benign biliary strictures (BBS) which can develop during the clinical course of acute biliary pancreatitis (ABP) due to compression of the common bile duct (CBD) by edematous and inflamed pancreatic tissue. We aimed to determine the incidence of BBS due to ABP and its clinical course after endoscopic management. METHODS The study was retrospectively conducted among patients with ABP who were admitted to a single tertiary reference center during 3 years. BBS-ABP was defined as distal narrowing of the CBD with proximal dilatation and delayed drainage of the contrast into the duodenum. Endoscopic treatment was performed by inserting a single 7F or 10F plastic stent which was exchanged every 3 months until stricture resolution. Patients were followed for 1 year after stricture resolution. RESULTS Seven hundred and twenty-one patients had ABP during the study period. Among them, 257 (35.6%) patients underwent ERCP and 26 patients (3.6%) had CBD stricture due to ABP. A 7 Fr plastic stent was inserted in 18 patients and 10 Fr in 8 patients. The stricture was completely resolved at 3 months in 66.7%, at 6 months 23.8% and at 9 months (9.5%) of the patients. There was no procedure-related complications other than asymptomatic stent migration in 4 (19%) patients. None of the patients had recurrent biliary stricture during the 1 year stent-free follow-up period. CONCLUSION BBS-ABP is a frequently seen clinical entity. In most patients, the stricture improves within 3 months and temporary endoscopic stenting prevents the patients from the consequences of the obstruction during this period.

Front Med (Lausanne) 2022; 9:969225. [PMID: 36186815 PMCID: PMC9515354 DOI: 10.3389/fmed.2022.969225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 08/23/2022] [Indexed: 11/13/2022] Open
Abstract
PurposeBiliary drainage is an important modality for extrahepatic obstructive jaundice both in patients with palliative and resectable. Currently, endoscopic biliary drainage is preferred in clinical practice, including endoscopic nasobiliary drainage (ENBD) and endoscopic biliary stenting (EBS), both of which have their own advantages and disadvantages. The purpose of our study was to compare the safety and efficacy of endoscopic biliary stenting (EBS) only vs. EBS plus nasobiliary drain for obstructive jaundice.MethodsWe consecutively reviewed patients with endoscopic biliary drainage in our institution from November 2014 to March 2021. Combined (ENBD plus stent) and single approach (EBS only) were defined as combined approach and single modality, respectively, and all eligible patients were divided into a combined approach group and a single modality group. We compared combined vs. single modality approaches to investigate whether there were statistical differences in liver chemistries, postoperative adverse events, and stent patency time.ResultsIn 271 patients, a total of 356 times endoscopic biliary drainages were performed. All eligible patients were divided into the combined approach group (n = 74) and the single modality group (n = 271). The combined approach was associated with a lower incidence of postoperative cholangitis and bleeding and greater improvement in liver chemistries, although it was not statistically significant. However, it was superior to the single modality group in terms of hospital stay (12.7 ± 5.2 vs. 14.5 ± 7.9 days, p = 0.020 < 0.05) and stent patency time (8.1 ± 3.9 vs. 4.3±2.7 months, p = 0.001 < 0.05).ConclusionEndoscopic combined (ENBD plus stent) drainage is a more advantageous biliary drainage method that is characterized by more adequate biliary drainage, a lower incidence of postoperative adverse events, and longer effective biliary drainage time.

Abstract
Introduction Stent insertion is the most frequently used option to treat malignant biliary obstruction (MBO) patients. Hilar cholangiocarcinoma (HCCA) is the most common disease that causes hilar MBO. Aim To assess the clinical efficacy and long-term outcomes of I-125 seed-loaded stent (ISS) insertion for HCCA patients. Material and methods Consecutive patients with HCCA underwent either normal stent (NS) or ISS insertion between January 2017 and December 2019. The baseline and treatment data of these two groups were compared. Results During the period, a total of 93 patients with inoperable HCCA were divided into either NS (n = 48) or ISS (n = 45) insertion groups at our centre. Technical success rates of the NS and ISS insertion were 91.7% and 95.6%, respectively (p = 0.733). Clinical success rates were 93.2% and 100% in the NS and ISS groups, respectively (p = 0.24). Stent dysfunction was observed in 11 and 8 patients in the NS and ISS groups, respectively (p = 0.47). The median stent patency was 143 days and 208 days in the NS and ISS groups, respectively (p < 0.001). All patients died in the follow-up period, with median survival duration of 178 days and 220 days in the NS and ISS groups, respectively (p < 0.001). ISS insertion was the only predictor of longer patency (p = 0.002) and survival (p = 0.01). Conclusions ISS insertion might achieve longer patency and overall survival in patients with inoperable HCCA as compared with NS insertion.

Use of stents in patients undergoing chemotherapy for borderline resectable pancreatic cancer-causing biliary obstruction while awaiting surgery: A cost-effectiveness analysis. Endosc Int Open 2021; 9:E1413-E1420.

Abstract
Background and study aims Biliary stenting is indicated to relieve obstruction from borderline resectable pancreatic cancer while patients receive preoperative neoadjuvant therapy. We compared the cost-effectiveness of plastic versus metal biliary stenting in this setting. Methods A decision tree analysis compares two competing types of biliary stents (initially metal vs. initially plastic) to treat malignant distal biliary obstruction while receiving neoadjuvant therapy with different scenarios including possible complications as bridge till the patient undergoes curative surgical attempt. Using published information, effectiveness was chosen as the probability of successfully reaching a state of being ready for surgery once chemotherapy was completed. Costs (2018 US$) were based on national data. A third-party payer perspective was adopted, and sensitivity analyses were performed over a time-horizon of one year. Results Initially inserting a metal versus a plastic biliary stent was more efficacious with a higher probability of reaching the readiness for surgery endpoint (96 % vs. 85 %), on average 18 days earlier while also being less expensive (US$ 9,304 vs. US$ 11,538). Sensitivity analyses confirmed robustness of these results across varying probability assumptions of plausible ranges and remained a dominant strategy even when lowering the willingness-to-pay threshold to US$ 1,000. Conclusions Initial metal stenting to relieve malignant biliary obstruction from borderline resectable pancreatic cancer in patients undergoing neoadjuvant therapy prior to surgery is a dominant intervention in economic terms, when compared to initially inserting a plastic biliary stent as it results in a greater proportion of patients being fit for surgery earlier and at a lower cost.

Best period to replace or change plastic stents with self-expandable metallic stents using multivariate competing risk regression analysis. Sci Rep 2020; 10:13080. [PMID: 32753642 PMCID: PMC7403588 DOI: 10.1038/s41598-020-70081-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Accepted: 07/23/2020] [Indexed: 12/18/2022] Open
Abstract
In endoscopic biliary drainage (EBD) for various benign and malignant biliary disorders, the appropriate timing to replace or change a plastic stent (PS) with a self-expandable metallic stent (SEMS) remains unclear. This study aimed to define the best period to replace or change a PS with a SEMS. Between January 1, 2012, and December 31, 2018, 1,887 consecutive EBD procedures, including 170 SEMS placements, were retrospectively identified. The period to recurrent biliary obstruction (PRBO) was estimated and compared between the malignant and benign groups and according to each disease using time to event analysis and competing risk analysis. Compared with the benign group, the malignant group had significantly shorter median PRBO with interquartile range (IQR) after PS placement [108 (39 – 270) vs. 613 (191 – 1,329) days, P < 0.001], even on multivariate analysis, with a subdistribution hazard ratio (SHR) of 3.58 (P < 0.001). The shortest PRBO distribution from the first quartile of the non-RBO period was seen in Mirizzi syndrome cases (25 days, P = 0.030, SHR = 3.32) in the benign group and in cases of pancreatic cancer (32 days, P = 0.041, SHR = 2.06); perihilar bile duct cancer (27 days, P = 0.006, SHR = 2.69); and ampullary cancer (22 days, P = 0.001, SHR = 3.78) in the malignant group. Our study supports that stent replacement for the benign group is feasible after 6 months, and the best period to replace or change a PS with a SEMS should be decided on the basis of the underlying disease to prevent RBO.

Abstract
OBJECTIVE To evaluate whether patients with malignant biliary obstruction (MBO) benefit from balloon dilation before the placement of a self-expanding metal stent (SEMS) for palliative biliary drainage. METHODS Consecutive patients who underwent endoscopic retrograde cholangiopancreatography with SEMS placement for palliative management of MBO were retrospectively included. Comparative analyses of serum bilirubin levels, post-procedural adverse events, stent patency time, stent dysfunction, and patient survival were performed between the dilation and non-dilation groups. RESULTS A total of 221 patients underwent palliative endoscopic SEMS implantation for MBO from January 2014 to June 2018. Dilation significantly improved the percentage of serum bilirubin improvement (37.0% vs 14.3%, P = 0.001), with a decreasing trend in the incidence of post-procedural cholangitis (2.5% vs 7.8%, P = 0.075), while the rates of other complications such as pancreatitis and bleeding were not increased. The patency time of SEMS and patient survival did not significantly differ between patients with and without dilation. Patients had endoscopic nasobiliary drainage (ENBD) but not dilation showed similar short-term outcomes as patients underwent dilation but without ENBD. CONCLUSIONS Dilation with a small-caliber balloon catheter before the placement of SEMS is a safe and effective approach for MBO. Balloon dilation may improve the short-term efficacy of SEMS placement, while long-term outcomes are not obviously affected. The short-term effect of stricture dilation may be achieved by ENBD. Further studies are needed to confirm our results.

Abstract
Biliary tract cancer, or cholangiocarcinoma, comprises a heterogeneous group of malignant tumors that can emerge at any part of the biliary tree. This group is the second most common type of primary liver cancer. Diagnosis is usually based on symptoms, which may be heterogeneous, and nonspecific biomarkers in serum and biopsy specimens, as well as on imaging techniques. Endoscopy-based diagnosis is essential, since it enables biopsy specimens to be taken. In addition, it can help with locoregional staging of distal tumors. Endoscopic retrograde cholangiopancreatography is a key technique for the evaluation and treatment of malignant biliary tumors. Correct staging of cholangiocarcinoma is essential in order to be able to determine the degree of resectability and assess the results of treatment. The tumor is staged based on the TNM classification of the American Joint Committee on Cancer. The approach will depend on the classification of the tumor. Thus, some patients with early-stage disease could benefit from surgery; complete surgical resection is the cornerstone of cure. However, only a minority of patients are diagnosed in the early stages and are suitable candidates for resection. In the subset of patients diagnosed with locally advanced or metastatic disease, chemotherapy has been used to improve outcome and to delay tumor progression. The approach to biliary tract tumors should be multidisciplinary, involving experienced endoscopists, oncologists, radiologists, and surgeons.

Abstract
PURPOSE To establish a new rat model, the pathogenesis of which is closer to the clinical occurrence of chronic obstructive jaundice with liver fibrosis. METHODS 90 SD rats were randomly divided into 3 groups. Group A common bile duct ligation, group B common bile duct injection compont and group C injection saline. The serum of three groups was extracted, and the liver function was detected by ELISA. HE staining, Masson staining and immunohistochemistry were used to detect liver pathology. RESULTS Group B showed a fluctuant development of jaundice, obstructive degree reached a peak at 2 weeks, and decreased from 3 weeks. HA, LA and PCIII were significantly higher than control group. 3 weeks after surgery, liver tissue fibrosis occurred in group B, and a wide range of fiber spacing was formed at 5 weeks. Immunohistochemistry showed that hepatic stellate cells were more active than the control group. CONCLUSION Intra-biliary injection of Compont gel is different from the classic obstructive jaundice animal model caused by classic bile duct ligation, which can provide an ideal rat model of chronic obstructive jaundice with liver fibrosis.

Abstract
Benign and malignant biliary strictures are common indications for endoscopic retrograde cholangiopancreatography. Diagnosis involves high-quality cross-sectional imaging and cholangiography with various endoscopic sampling techniques. Treatment options include placement of plastic biliary stents and self-expanding metal stents, which differ in patency duration and cost effectiveness. Whether the etiology is benign or malignant, a multidisciplinary strategy should be implemented. This article will discuss general principles of biliary stenting in both benign and malignant conditions.

Abstract
BACKGROUND Management of the primary and secondary tumors of the bile ducts still remains as a major clinical challenge. Radiofrequency (RF) ablation (RFA) of these tumors is feasible but the effect of RF energy on the human common bile duct (CBD) and surrounding tissues has not been investigated. This pilot study aimed to determine the relationship between RF energy and the depth of ablation in the normal human CBD. METHODS The study was performed on fresh ex vivo human biliary-pancreatic tissue which had been resected for a pancreatic cyst or mass. The study was conducted within 15 min after resection. A bipolar Habib RFA catheter was placed into the middle of the intact CBD, and three different (5, 7, 10 W) power settings were applied over a 90-s period by an RF generator. Gross and histological examinations were performed. The depth of coagulation necrosis in CBD and the effect of RFA on CBD wall and surrounding pancreas tissue were determined by microscopic examination. RESULTS The study included eight tissue samples. 5 W power was applied to three sites and RFA caused only focal epithelial necrosis limited to the CBD mucosa. 7 and 10 W were applied to five sites and coagulation necrosis occurred in all cases. Microscopically, necrosis was transmural, involved accessory bile duct glands, and extended to the surrounding pancreatic tissue in four of these cases. Macroscopically, RFA resulted in circumferential white-yellowish color change extending approximately 2 cm of the CBD. CONCLUSION Bipolar RF energy application with 5 W resulted in limited ablation on CBD wall. However, 7 and 10 W generated tissue necrosis which extended through the CBD wall and into surrounding pancreas tissue. Endoscopic biliary RFA is an effective technique for local biliary tissue ablation but the use of high energy may injure surrounding tissue.

Abstract
BACKGROUND AND STUDY AIM Endoscopic biliary drainage for malignant distal biliary obstruction (MDBO) is a common practice. Controversy persists with regard to its role in resectable MDBO, the optimal technical method and type of stent. The aim of this study was to evaluate practice patterns in the treatment of MDBO among endoscopists with varying levels of experience and practice backgrounds. METHODS Electronic survey distributed to members of the American Society for Gastrointestinal Endoscopy (ASGE). The main outcome measures included practice setting (academic vs. community), volume of endoscopic retrograde cholangiopancreatographies (ERCPs), reasons for endoscopic drainage in MDBO, and technical approach. RESULTS A total of 335 subjects (54 % community-based endoscopists) completed the survey. Most academic physicians (69 %) reported performing ≥ 150 ERCPs annually compared to 18.8 % of community physicians ( P < 0.001). In aggregate, 13.1 % of respondents performed ERCP in resectable MDBO because of surgeon preference or as the standard of care at their institution. The use of metal vs. plastic stents in MDBO varied based on practice setting. Routine sphincterotomy for MDBO was more common among community (78 %) vs academic endoscopists (61.1 %) ( P < 0.001). Over half (58 %) of the subjects avoided covering the cystic duct take-off during stenting MDBO if there was a gallbladder in situ. CONCLUSION There is significant variability in practice patterns for the treatment of MDBO. In spite of the recent ASGE guideline recommendations, some patients with resectable MDBO still undergo preoperative ERCP. Current clinical practices are not clearly supported by available data and underscore the need to increase adherence to gastrointestinal societal recommendations and an evidence-based approach to standardized patient care.

Abstract
OBJECTIVES Self-expandable metal stents (SEMS) are thought to have an advantage over plastic stents in achieving biliary drainage. METHODS We performed a systematic search of MEDLINE, EMBASE, Scopus, CENTRAL, and ISI Web of knowledge databases, from January 1980 to September 2015, for randomized-controlled trials (RCTs) comparing SEMS vs. plastic stents in the palliation of malignant biliary obstruction. Primary outcomes were durations of stent patency, patient survival, and 30-day mortality. Numerous secondary outcomes were assessed, and extensive sensitivity and subgroup analyses were performed. RESULTS In all, 20 RCTs totaling 1,713 patients yielded a weighted mean difference (WMD) in time to stent patency (4 studies) of 4.45 months (95% confidence interval (CI), 0.31, 8.59; GRADE=moderate) favoring SEMS. There were no differences in overall patient survival (5 studies) WMD=0.67 months (95% CI, -0.66, 1.99; GRADE=moderate), or 30-day mortality (8 studies) odds ratio (OR)=0.80 (95% CI, 0.52, 1.24; GRADE=moderate) but there was a higher symptom-free survival at 6 months (4 studies) OR=5.96 (95% CI, 1.71, 20.81; GRADE=moderate). SEMS use resulted in lower rates of late complications (11 studies) OR=0.43 (95% CI, 0.26, 0.71; GRADE=moderate), sepsis or cholangitis (14 studies) OR=0.53 (95% CI, 0.37, 0.77; GRADE=high), blocking from sludge (8 studies) OR=0.11(95% CI, 0.07, 0.17; GRADE=moderate), and mean number of re-interventions (8 studies) WMD=-0.83 interventions (95% CI, -1.64, -0.02; GRADE=moderate). There was a longer patency of SEMS for those without a prior drainage attempt (2 studies) WMD 7.70 months (95% CI, 7.14, 8.25; GRADE=high). Although a survival advantage was found when an uncovered SEMS was used (3 studies) WMD 1.31 months (95% CI, 0.30, 2.32; GRADE=high), but not partially or fully covered SEMS (2 studies) WMD -0.66 months (95% CI, -1.02, -0.30; GRADE=high) vs. plastic stents, and for SEMS in the setting of pre- or post-procedural antibiotic administration (2 studies) WMD 1.49 months (95% CI, 0.27, 2.70; GRADE=high), and performance of a sphincterotomy (2 studies) WMD 1.63 months (95% CI, 0.42, 2.84; GRADE=high). CONCLUSIONS Keeping in mind the noted risk of bias in source data, the use of SEMS compared with plastic stents, in the palliation of patients with malignant biliary obstruction results in longer stent patency, lower complications rates, and fewer re-interventions, whereas exhibiting survival benefits in selected subgroups of patients.

Abstract
Endoscopic ultrasound-guided biliary drainage (EUS-BD) is an attractive option for patients who cannot undergo conventional endoscopic retrograde cholangiopancreatography (ERCP) and do not want surgery or percutaneous drainage procedures. We present the use of EUS-antegrade (EUS-AG) insertion of a self-expandable metal stent (SEMS) in a patient with a common hepatic duct cholangiocarcinoma, as well as a huge gastric lipoma, after recurrent biliary obstruction of a prior SEMS inserted via ERCP in the same session as a duodenal stent insertion for gastric outlet obstruction.
