Propensity score matching analysis for clinical impact of braided-type versus laser-cut-type covered self-expandable metal stents for endoscopic ultrasound-guided hepaticogastrostomy

Background:To prevent stent migration during endoscopic ultrasound-guided hepaticogastrostomy(EUS-HGS),intra-scope channel release technique is important,but is unfamiliar to non-expert hands.The self-expandable metal stent(SEMS)is an additional factor to prevent stent migration.However,no compara-tive studies of laser-cut-type and braided-type during EUS-HGS have been reported.The aim of this study was to compare the distance between the intrahepatic bile duct and stomach wall after EUS-HGS among laser-cut-type and braided-type SEMS.Methods:To evaluate stent anchoring function,we measured the distance between the hepatic parenchyma and stomach wall before EUS-HGS,one day after EUS-HGS,and 7 days after EUS-HGS.Also,propensity score matching was performed to create a propensity score for using laser-cut-type group and braided-type group.Results:A total of 142 patients were enrolled in this study.Among them,24 patients underwent EUS-HGS using a laser-cut-type SEMS,and 118 patients underwent EUS-HGS using a braided-type SEMS.EUS-HGS using the laser-cut-type SEMS was mainly performed by non-expert endoscopists(n=21);EUS-HGS using braided-type SEMS was mainly performed by expert endoscopists(n=98).The distance after 1 day was significantly shorter in the laser-cut-type group than that in the braided-type group[2.00(1.70-3.75)vs.6.90(3.72-11.70)mm,P<0.001].In addition,this distance remained significantly shorter in the laser-cut-type group after 7 days.Although these results were similar after propensity score matching analysis,the distance between hepatic parenchyma and stomach after 7 days was increased by 4 mm compared with the distance after 1 day in the braided-type group.On the other hand,in the laser-cut-type group,the distance after 1 day and 7 days was almost the same.Conclusions:EUS-HGS using a laser-cut-type SEMS may be safe to prevent stent migration,even in non-expert hands.

Endoscopic band ligation or endoscopic tissue adhesive injection in the treatment of gastric varices:Which is better?

The combination of endoscopic ultrasound with endoscopic treatment of type 1 gastric variceal hemorrhage may improve the robustness and generalizability of the findings in future studies.Moreover,the esophageal varices should also be included in the evaluation of treatment efficacy in subsequent studies to reach a more convincing conclusion.

Effect of endoscopic sphincterotomy and endoscopic papillary balloon dilation endoscopic retrograde cholangiopancreatographies on the sphincter of Oddi

BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP),with its clinical ad-vantages of less trauma and faster recovery,has become the primary treatment for choledocholithiasis.AIM To investigate the effects of different ERCP procedures on the sphincter of Oddi.METHODS The clinical data of 91 patients who underwent ERCP at Yixing Hospital of Traditional Chinese Medicine between February 2018 and February 2021 were analyzed retrospectively.The patients were divided into endoscopic sphinc-terotomy(EST,n=24)and endoscopic papillary balloon dilation(EPBD,n=67)groups.The duration of operation,pancreatic development,pancreatic sphinc-terotomy,intubation difficulties,stone recurrence,and incidence of reflux cho-langitis and cholecystitis were statistically analyzed in patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction in the EST and EPBD groups.RESULTS Differences in hypertension,diabetes,increased bilirubin,small diameter of the common bile duct,or ampullary diverticulum between the two groups were not significant.Statistically significant differences were observed between the two groups concerning sex and age(<60 years).Patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction were higher in the EST group than in the EPBD group.The number of cases of pancreatic development,pancreatic duct sphincterotomy,and difficult intubation were higher in the EST group than in the EPBD group.The number of Oddi’s sphincter manometries,ERCP surgical outcomes,and guidewires entering the pancreatic duct several times in EST group were lower than those in the EPBD group.The numbers of stone recurrences,reflux cholangitis,and cholecystitis were higher in the EST group than in the EPBD group.CONCLUSION In summary,common bile duct stones,pancreatitis history,and multiple guided wire introductions into the pancreatic duct are independent risk factors for EST and EPBD.Based on this evidence,this study can provide actionable insights for clinicians and researchers.

Early endoscopic management of an infected acute necrotic collection misdiagnosed as a pancreatic pseudocyst: A case report

BACKGROUND Infected acute necrotic collection(ANC)is a fatal complication of acute pancre-atitis with substantial morbidity and mortality.Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis;however,there is great controversy about the optimal drainage time,and better treatment should be explored.CASE SUMMARY We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancre-atitis;conservative treatment was ineffective,and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography(CT).Endoscopic ultra-sonography(EUS)suggested hyperechoic necrotic tissue within the cyst cavity.The wall was not completely mature,and the culture of the puncture fluid was positive for A-haemolytic Streptococcus.Thus,the final diagnosis of ANC in-fection was made.The necrotic collection was not walled off and contained many solid components;therefore,the patient underwent EUS-guided aspiration and lavage.Two weeks after the collection was completely encapsulated,pancreatic duct stent drainage via endoscopic retrograde cholangiopancreatography(ERCP)was performed,and the patient was subsequently successfully discharged.On repeat CT,the pancreatic cysts had almost disappeared during the 6-month fo-llow-up period after surgery.CONCLUSION Early EUS-guided aspiration and lavage combined with late ERCP catheter drainage may be effective methods for intervention in infected ANCs.

Practical approach to linear endoscopic ultrasound examination of the gallbladder

The gallbladder(GB)is a susceptible organ,prone to various pathologies that can be identified using different imaging techniques.Transabdominal ultrasound(TUS)is typically the initial diagnostic method due to its numerous well-established advantages.However,in cases of uncertainty or when a definitive diagnosis cannot be established,computed tomography(CT)or magnetic resonance imaging may be employed to provide more detailed information.Nevertheless,CT scans may sometimes offer inadequate spatial resolution,which can limit the differentiation of GB lesions,particularly when smaller yet clinically relevant abnormalities are involved.Conversely,endoscopic ultrasound(EUS)provides higher frequency compared to TUS,superior spatial resolution,and the option for contrast-enhanced harmonic imaging,enabling a more comprehensive examination.Thus,EUS can serve as a supplementary tool when conventional imaging methods are insufficient.This review will describe the standard EUS examination of the GB,focusing on its endosonographic characteristics in various GB path-ologies.

Editorial article to:Animal experimental study on magnetic anchor technique-assisted endoscopic submucosal dissection of early gastric cancer

In this editorial we comment on the article published in the recent issue of the World Journal of Gastrointestinal Endoscopy 2023;15(11):634-680.Gastric cancer(GC)remains the fifth most common malignancy and the fourth leading cause of cancer-related death worldwide.The overall prevalence of GC has declined,although that of proximal GC has increased over time.Thus,a significant proportion of GC cases and deaths can be avoided if preventive interventions are taken.Early GC(EGC)is defined as GC confined to the mucosa or submucosa.Endoscopic resection is considered the most appropriate treatment for precancerous gastrointestinal lesions improving patient quality of life,with reduced rates of complications,shorter hospitalization period,and lower costs when compared to surgical resection.Endoscopic mucosal resection(EMR)and endoscopic sub-mucosal dissection(ESD)are representative endoscopic treatments for EGC and precancerous gastric lesions.Standard EMR implies injection of a saline solution into the sub-mucosal space,followed by excision of the lesion using a snare.Complete resection rates vary depending on the size and severity of the lesion.When using conventional EMR methods for lesions less than 1 cm in size,the complete resection rate is approximately 60%,whereas for lesions larger than 2 cm,the complete resection rate is low(20%-30%).ESD can be used to remove tumors exceeding 2 cm in diameter and lesions associated with ulcers or submucosal fibrosis.Compared with EMR,ESD has higher en bloc resection rates(90.2%vs 51.7%),higher complete resection rates(82.1 vs 42.2%),and lower recurrence rates(0.65%vs 6.05%).Thus,innovative techniques have been introduced.

Endoscopic-ultrasound-guided biliary drainage with placement of electrocautery-enhanced lumen-apposing metal stent for palliation of malignant biliary obstruction:Updated meta-analysis

BACKGROUND Endoscopic ultrasound-guided biliary drainage using electrocautery-enhanced(ECE)delivery of lumen-apposing metal stent(LAMS)is gradually being re-cognized as a viable palliative technique for malignant biliary obstruction after endoscopic retrograde cholangiopancreatography(ERCP)failure.However,most of the studies that have assessed its efficacy and safety were small and hetero-geneous.Prior meta-analyses of six or fewer studies that were published 2 years ago were therefore underpowered to yield convincing evidence.AIM To update the efficacy and safety of ECE-LAMS for treatment of biliary ob-struction after ERCP failure.METHODS We searched PubMed,EMBASE,and Scopus databases from the inception of the ECE technique to May 13,2022.Primary outcome measure was pooled technical success rate,and secondary outcomes were pooled rates of clinical success,re-intervention,and adverse events.Meta-analysis was performed using a random-effects model following Freeman-Tukey double-arcsine transformation in R soft-ware(version 4.1.3).RESULTS Fourteen eligible studies involving 620 participants were ultimately included.The pooled rate of technical success was 96.7%,and clinical success was 91.0%.Adverse events were reported in 17.5%of patients.Overall reinter-vention rate was 7.3%.Subgroup analyses showed results were generally consistent.CONCLUSION ECE-LAMS has favorable success with acceptable adverse events in relieving biliary obstruction when ERCP is impossible.The consistency of results across most subgroups suggested that this is a generalizable approach.

Endoscopic features and treatments of gastric cystica profunda

BACKGROUND Gastric cystica profunda(GCP)represents a rare condition characterized by cystic dilation of gastric glands within the mucosal and/or submucosal layers.GCP is often linked to,or may progress into,early gastric cancer(EGC).AIM To provide a comprehensive evaluation of the endoscopic features of GCP while assessing the efficacy of endoscopic treatment,thereby offering guidance for diagnosis and treatment.METHODS This retrospective study involved 104 patients with GCP who underwent endoscopic resection.Alongside demographic and clinical data,regular patient followups were conducted to assess local recurrence.RESULTS Among the 104 patients diagnosed with GCP who underwent endoscopic resection,12.5%had a history of previous gastric procedures.The primary site predominantly affected was the cardia(38.5%,n=40).GCP commonly exhibited intraluminal growth(99%),regular presentation(74.0%),and ulcerative mucosa(61.5%).The leading endoscopic feature was the mucosal lesion type(59.6%,n=62).The average maximum diameter was 20.9±15.3 mm,with mucosal involvement in 60.6%(n=63).Procedures lasted 73.9±57.5 min,achieving complete resection in 91.3%(n=95).Recurrence(4.8%)was managed via either surgical intervention(n=1)or through endoscopic resection(n=4).Final pathology confirmed that 59.6%of GCP cases were associated with EGC.Univariate analysis indicated that elderly males were more susceptible to GCP associated with EGC.Conversely,multivariate analysis identified lesion morphology and endoscopic features as significant risk factors.Survival analysis demonstrated no statistically significant difference in recurrence between GCP with and without EGC(P=0.72).CONCLUSION The findings suggested that endoscopic resection might serve as an effective and minimally invasive treatment for GCP with or without EGC.

Efficacy and safety of endoscopic submucosal dissection for early gastric cancer and precancerous lesions in elderly patients

BACKGROUND With advancements in the development of endoscopic technologies,the endo-scopic submucosal dissection(ESD)has been one of the gold-standard therapies for early gastric cancer.AIM To investigate the efficacy and safety ESD in the treatment of early gastric cancer and precancerous lesions in the elderly patients.METHODS Seventy-eight elderly patients with early gastric cancer and precancerous lesions admitted to the Third Affiliated Hospital of Qiqihar Medical University were se-lected and classified into two groups according to the different surgical therapies they received between January 2021 and June 2022.Among them,39 patients treated with ESD were included in an experimental group,and 39 patients treated with endoscopic mucosal resection(EMR)were included in a control group.We compared the basic intraoperative conditions,postoperative short-term recovery,long-term recovery effects and functional status of gastric mucosa between the two groups;the basic intraoperative conditions included lesion resection,intra-operative bleeding and operation time;the postoperative short-term recovery assessment indexes were length of hospital stay and incidence of surgical complic-ations;and the long-term recovery assessment indexes were the recurrence rate at 1 year postoperatively and the survival situation at 1 year and 3 years postoper-atively;and we compared the preoperative and predischarge serum pepsinogen I(PG I)and PG II levels and PG I/PG II ratio in the two groups before surgery and discharge.RESULTS The curative resection rate and the rate of en bloc resection were higher in the experimental group than in the control group.The intraoperative bleeding volume was higher in the experimental group than in the control group.The operation time was longer in the experimental group than that in the control group,and the rate for base residual focus was lower in the experimental group than that of the control group,and the differences were all statistically significant(all P<0.05).The length of hospital stay was longer in the experi-mental group than in the control group,and the incidence of surgical complications,1-year postoperative recu-rrence rate and 3-year postoperative survival rate were lower in the experimental group than in the control group,and the differences were statistically significant(all P<0.05).However,the difference in the 1-year postoperative survival rate was not statistically significant between the two groups(P>0.05).Before discharge,PG I and PG I/PG II ratio were elevated in both groups compared with the preoperative period,and the above indexes were higher in the experimental group than those in the control group,and the differences were statistically significant(both P<0.05).Moreover,before discharge,PG II level was lower in both groups compared with the preoperative period,and the level was lower in the experimental group than in the control group,and the differences were all statistically significant(all P<0.05).CONCLUSION Compared with EMR,ESD surgery is more thorough.It reduces the rate of base residual focus,recurrence rate,surgical complications,and promotes the recovery of gastric cells and glandular function.It is safe and suitable for clinical application.

Use of endoscopic ultrasound-guided gallbladder drainage as a rescue approach in cases of unsuccessful biliary drainage

This narrative review provides an overview of the utilization of endoscopic ultrasound-guided gallbladder drainage(EUS-GBD)as a salvage approach in cases of unsuccessful conventional management.EUS-GBD is a minimally invasive and effective technique for drainage in patients with acute cholecystitis with high risk of surgery.The procedure has demonstrated impressive technical and clinical success rates with low rates of adverse events,making it a safe and effective option for appropriate candidates.Furthermore,EUS-GBD can also serve as a rescue option for patients who have failed endoscopic retrograde cholangiopancreatography or EUS biliary drainage for relief of jaundice in malignant biliary stricture.However,patient selection is critical for the success of EUS-GBD,and proper patient selection and risk assessment are important to ensure the safety and efficacy of the procedure.As the field continues to evolve and mature,ongoing research will further refine our understanding of the benefits and limitations of EUS-GBD,ultimately leading to improved outcomes for patients.

Exploring non-curative endoscopic submucosal dissection:Current treatment optimization and future indication expansion

The increasing popularity of endoscopic submucosal dissection(ESD)as a treatment for early gastric cancer has highlighted the importance of quality assessment in achieving curative resections.This article emphasizes the significance of evaluating ESD quality,not only for curative cases but also for non-curative ones.Postoperative assessment relies on the endoscopic curability(eCura)classification,but management strategies for eCuraC-1 tumour with a positive horizontal margin are unclear.Current research primarily focuses on comparing additional surgical procedures in high-risk patients,while studies specifically targeting eCuraC-1 patients are limited.Exploring management strategies and follow-up outcomes for such cases could provide valuable insights.Furthermore,the application of molecular imaging using near-infrared fluorescent tracers holds promise for precise tumour diagnosis and navigation,potentially impacting the management of early-stage gastric cancer patients.Advancing research in these areas is essential for improving the overall efficacy of endoscopic techniques and refining treatment indications.

Gastroesophageal reflux after per-oral endoscopic myotomy:Management literature

In this editorial,we respond to a review article by Nabi et al,in which the authors discussed gastroesophageal reflux(GER)following peroral endoscopic myotomy(POEM).POEM is presently the primary therapeutic option for achalasia,which is both safe and effective.A few adverse effects were documented after POEM,including GER.The diagnostic criteria were not clear enough because approximately 60%of patients have a long acid exposure time,while only 10%experience reflux symptoms.Multiple predictors of high disease incidence have been identified,including old age,female sex,obesity,and a baseline lower esophageal sphincter pressure of less than 45 mmHg.Some technical steps during the procedure,such as a lengthy or full-thickness myotomy,may further enhance the risk.Proton pump inhibitors are currently the first line of treatment.Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method,such as peroral endoscopic fundoplication or transoral incisionless fundoplication.However,more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.

Endoscopic submucosal dissection and endoscopic mucosal resection for esophageal and gastric lesions:A comparison of procedures

Objective Esophageal and gastric lesions are effectively managed with minimally invasive upper endoscopic procedures such as endoscopic mucosa resection(EMR)and endoscopic submucosal dissection(ESD),offering patients alternatives to invasive interventions.While ESD is well established in Eastern Asia,its adoption in Denmark for superficial esophageal cancer is recent.This study presents real-world data on the feasibility,safety,and hospitalization duration associated with ESD and EMR for esophageal and gastric lesions.Methods A retrospective analysis was conducted on patients who underwent ESD or EMR at a specialized center in Denmark from October 2016 to June 2022.Data on treatment,indication,lesion location,hospitalization duration,procedure duration,specimen size,complications,recurrence,and one-year overall survival were collected.Statistical comparisons utilized the Mann-Whitney U test,independent sample median test,and chi-squared test.Results The study included 130 patients(144 procedures):72 underwent ESD and 58 underwent EMR.Compared with EMR,ESD resulted in greater percentages of en bloc and R0 resections(98.8%vs.64.1%,p<0.001;and 83.9%vs.23.8%,p<0.001),greater complication rates(28.7%vs.3.1%,p<0.001)and longer procedure times(119.5 min vs.37.0 min,p<0.001).The ESD procedure time significantly decreased over time(p=0.01).The local recurrence rates were 14.5%for ESD and 23.8%for EMR(p=0.767).The one-year overall survival rates were similar between the groups(95.8%vs.94.8%,p=0.553).Conclusion Both ESD and EMR are safe and viable for treating esophageal and gastric lesions.ESD offers advantages but requires more time and skill.These findings support the literature,emphasizing the importance of considering patient-specific factors and surgeon proficiency in selecting the appropriate procedure.

Endoscopic submucosal dissection vs transanal endoscopic surgery for rectal tumors: A systematic review and meta-analysis

BACKGROUND Endoscopic submucosal dissection(ESD)and transanal endoscopic submucosal dissection(TES)are widely employed surgical techniques.However,the comparative efficacy and safety of both remain inconclusive.AIM To comprehensively analyze and discern differences in surgical outcomes between ESD and TES.METHODS We conducted a systematic search of the electronic databases PubMed,Embase,Cochrane Central Register of Controlled Trials,Scopus,and CINAHL from inception till August 2023.We analyzed outcomes including recurrence rate,en bloc resection,R0 resection rate,perforation rate,procedure length,and hospital stay length applying a random-effects inverse-variance model.We assessed publication bias by conducting an Egger’s regression test and sensitivity analyses.RESULTS We pooled data from 11 studies involving 1013 participants.We found similar recurrence rates,with a pooled odds ratio of 0.545(95%CI:0.176-1.687).En bloc resection,R0 resection,and perforation rate values were also similar for both ESD and TES.The pooled analysis for procedure length indicated a mean difference of-4.19 min(95%CI:-22.73 to 14.35),and the hospital stay was on average shorter for ESDs by about 0.789 days(95%CI:-1.671 to 0.093).CONCLUSION Both ESD and TES displayed similar efficacy and safety profiles across multiple outcomes.Our findings show that individualized patient and surgeon preferences,alongside specific clinical contexts,can be considered when selecting between these two techniques.

Endoscopic ultrasound-guided biliary drainage using electrocauteryenhanced lumen-apposing metal stent for malignant biliary obstruction:A promising procedure

In this editorial,we comment on the article by Peng et al.Palliative drainage for biliary obstruction resulting from unresectable malignant lesions includes internal and external drainage.The procedures of biliary drainage are usually guided by fluoroscopy or transcutaneous ultrasound,endoscopic ultrasound(EUS),or both.Endoscopic retrograde cholangiopancreatography(ERCP)has been primarily recommended for the management of biliary obstruction,while EUS-guided biliary drainage and percutaneous transhepatic biliary drainage(PTBD)are alternative choices for cases where ERCP has failed or is impossible.PTBD is limited by shortcomings of a higher rate of adverse events,more reinterventions,and severe complications.EUS-guided biliary drainage has a lower rate of adverse events than PTBD.EUS-guided biliary drainage with electrocautery-enhanced lumen-apposing metal stent(ECE-LAMS)enables EUS-guided biliaryenteric anastomosis to be performed in a single step and does not require prior bile duct puncture or a guidewire.The present meta-analysis showed that ECELAMS has a high efficacy and safety in relieving biliary obstruction in general,although the results of LAMS depending on the site of biliary obstruction.This study has highlighted the latest advances with a larger sample-based comprehensive analysis.

Endoscopic ultrasound-guided biliary drainage after failed endoscopic retrograde cholangiopancreatography: The road is open for almighty biliopancreatic endoscopists!

Commentary on the article written and published by Peng et al,investigating the role of endoscopic ultrasound(EUS)-guided biliary drainage for palliation of malignant biliary obstruction after failed endoscopic retrograde cholangiopan-creatography(ERCP).For 40 years endoscopic biliary drainage was synonymous with ERCP,and EUS was used mainly for diagnostic purposes.The advent of therapeutic EUS has revolutionized the field,especially with the development of a novel device such as electrocautery-enhanced lumen-apposing metal stents.Complete biliopancreatic endoscopists with both skills in ERCP and in interven-tional EUS,would be ideally suited to ensure patients the best drainage technique according to each individual situation.

Role of endoscopic ultrasound-guided biliary drainage for palliation of malignant biliary obstruction

Endoscopic ultrasound-guided biliary drainage(EUS-BD)directs bile flow into the digestive tract and has been mostly used in patients with malignant biliary obstruction(MBO)where endoscopic retrograde cholangiopancreatography-guided biliary drainage was unsuccessful or was not feasible.Lumen apposing metal stents(LAMS)are deployed during EUS-BD,with the newer electrocautery-enhanced LAMS reducing procedure time and complication rates due to the inbuilt cautery at the catheter tip.EUS-BD with electrocautery-enhanced LAMS has high technical and clinical success rates for palliation of MBO,with bleeding,cholangitis,and stent occlusion being the most common adverse events.Recent studies have even suggested comparable efficacy between EUS-BD and endosc-opic retrograde cholangiopancreatography as the primary approach for distal MBO.In this editorial,we commented on the article by Peng et al published in the recent issue of the World Journal of Gastrointestinal Surgery in 2024.

Effect of endoscopic submucosal dissection on gastrointestinal function and nutritional status in patients with early gastric cancer

BACKGROUND Gastric cancer(GC)endangers the survival and prognosis of patients worldwide.Improving the prognosis of patients with early GC(EGC)is crucial to prolong their survival time.AIM To analyze the effects of endoscopic submucosal dissection(ESD)on gastrointestinal function and nutritional status in patients with EGC.METHODS Eighty patients with EGC between January 2021 and January 2024 were divided according to different surgical protocol into following two groups:42 patients who underwent ESD in the ESD group and 38 patients treated with endoscopic mucosal resection(EMR)in the EMR group.Two groups were compared in the operative indices,lesion resection rate,postoperative recovery of gastrointestinal function,nutritional status,and incidence of surgical complications.RESULTS The overall resection rate of the lesion in the ESD group was higher.The operative bleeding volume and operation time were higher and gastrointestinal ventilation time was shorter in the ESD group than those in the EMR group(P<0.05).The nutritional statuses of the two groups decreased after operation;however,the levels of albumin,prealbumin,hemoglobin,and transferrin were higher in the ESD group than in the EMR group(P<0.05).The post-operative pepsinogen(PG)I level in the ESD group was higher than that in the EMR group,and the PG II level was lower than that in the EMR group(P<0.05).The incidence of postoperative complications was compared between the two groups(P>0.05).CONCLUSION ESD can promote the immediate recovery of patient’s postoperative gastrointestinal function,improve their nutritional level,and signifies its application in patients with EGC.

Revolutionizing palliative care:Electrocautery-enhanced lumenapposing metal stents in endoscopic-ultrasound-guided biliary drainage for malignant obstructions

Patients with malignant biliary obstruction,following endoscopic retrograde cholangiopancreatography(ERCP)failure could be referred for endoscopicultrasound-guided biliary drainage through electrocautery-enhanced(ECE)lumen-apposing metal stent(LAMS)placement.However,the efficacy and safety of ECE-LAMS in this scenario have remained debatable due to minimal scientific evidence.The current confirmed 91.0%clinical success,96.7%technical success,7.3%reintervention rate,and 17.5%adverse events,following the treatment of malignant biliary obstruction with ECE-LAMS delivery.Finally,ECE-LAMS proved to be a generalizable strategy for managing biliary obstruction for patients who were excluded from ERCP.
