Abstract
Background and study aims Endobiliary radiofrequency ablation (RFA) can be an effective palliative treatment, but few studies have evaluated its outcomes for malignant obstruction in the hilar bile duct, which has a thin wall and complex duct-vascular contacts. We evaluated the efficacy and safety of temperature-controlled endobiliary RFA, which can reduce the risk of unintentional thermal injury by maintaining the temperature of the ablation segment, in the treatment of inoperable hilar cholangiocarcinoma (CCA). Patients and methods After propensity score matching, 64 patients with inoperable hilar CCA were categorized to the RFA + stent group (endobiliary RFA with stenting; n=32) or stent-only group (stenting only; n=32). The evaluated outcomes were the median time to recurrent biliary obstruction (RBO), overall survival (OS), and adverse events (AEs). Results Technical success was achieved in all patients. The clinical success rate was 93.8% in the RFA + stent group and 87.5% in the stent-only group ( P =0.672). The median time to RBO was 242 days in the RFA + stent group and 168 days in the stent-only group ( P =0.031). The median OS showed a non-significant tendency to be higher in the RFA + stent group (337 versus 296 days; P =0.260). Overall AE rates were comparable between the two groups (12.5% vs 9.4%, P =1.000). Conclusions Temperature-controlled endobiliary RFA resulted in favorable stent patency without increasing the rate of AEs but it did not significantly increase OS in patients with inoperable hilar CCA (Clinical trial registration number: KCT0008576).

Abstract
INTRODUCTION Endoscopic ultrasound (EUS)-guided drainage of symptomatic pancreatic fluid collections (PFCs) using the Hot-Axios device has recently been associated with a significant risk of bleeding. This adverse event (AE) seems to occur less frequently with the use of a different device, the Spaxus stent. The aim of the current study was to compare the rates of bleeding between the two stents. METHODS Patients admitted for treatment of PFCs by EUS plus lumen-apposing metal stent in 18 endoscopy referral centers between 10 July 2019 and 28 February 2022 were identified and their outcomes compared using a propensity-matching analysis. RESULTS 363 patients were evaluated. After a 1-to-1 propensity score match, 264 patients were selected (132 per group). The technical and clinical success rates were comparable between the two groups. Significantly more bleeding requiring transfusion and/or intervention occurred in the Hot-Axios group than in the Spaxus group (6.8% vs. 1.5%; P = 0.03); stent type was a significant predictor of bleeding in both univariate and multivariate regression analyses (P = 0.03 and 0.04, respectively). Bleeding necessitating arterial embolization did not however differ significantly between the two groups (3.0% vs. 0%; P = 0.12). In addition, the Hot-Axios was associated with a significantly higher rate of overall AEs compared with the Spaxus stent (9.8% vs. 3.0%; P = 0.04). CONCLUSION Our study showed that, in patients with PFCs, bleeding requiring transfusion and/or intervention occurred significantly more frequently with use of the Hot-Axios stent than with the Spaxus stent, although this was not the case for bleeding requiring embolization.

Abstract
Background/Aims : Peroral cholangioscopy (POC) has been used to assess intrahepatic duct (IHD) lesions but with a limited role. A new multibending (MB) ultraslim endoscope has been designed to improve POC performance. We evaluated the usefulness of POC using the MB ultraslim endoscope for the management of IHD lesions. Methods : Between March 2017 and March 2020, 22 patients underwent direct POC using the MB ultraslim endoscope for IHD lesions documented by previous imaging or cholangiopancreatography. The primary outcome was technical success of POC, and secondary outcomes were technical success of POC-guided interventions, median procedure time, and POC-related adverse events. Results : The technical success rate for POC using the MB ultraslim endoscope for IHD lesions was 95.5% (21/22). Free-hand insertion was successful in 95.2% (20/21). The overall technical success rate for POC-guided intervention was 100% (21/21), including nine diagnostic and 12 therapeutic procedures (eight direct stone removal and four intraductal lithotripsies). The median procedure time was 29 minutes (range, 9 to 79 minutes). There were no procedure-related adverse events. Conclusions : Direct POC using the MB ultraslim endoscope allows direct visualization of IHD lesions and may be useful for diagnosis and therapeutic management in selected patients.

Abstract
OBJECTIVES Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in patients with distal malignant biliary obstruction (DMBO). Biliary drainage using electrocautery lumen apposing metal stent (EC-LAMS) is currently a well-established procedure when ERCP fails. In a palliative setting the endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) could represent an easy and valid option. We performed a prospective study with a new EC-LAMS with the primary aim to assess the clinical success rate of EUS-GBD as a first-line approach to the palliation of DMBO. METHODS In all, 37 consecutive patients undergoing EUS-GBD with a new EC-LAMS were prospectively enrolled. Clinical success was defined as bilirubin level decrease >15% within 24 h and >50% within 14 days after EC-LAMS placement. RESULTS The mean age was 73.5 ± 10.8 years; there were 17 male patients (45.9%). EC-LAMS placement was technically feasible in all patients (100%) and the clinical success rate was 100%. Four patients (10.8%) experienced adverse events, one bleeding, one food impaction, and two cystic duct obstructions because of disease progression. No stent-related deaths were observed. The mean hospitalization was 7.7 ± 3.4 days. Median overall survival was 4 months (95% confidence interval 1-8). CONCLUSION Endoscopic ultrasound-guided gallbladder drainage with the new EC-LAMS is a valid option in palliative endoscopic biliary drainage as a first-step approach in low survival patients with malignant jaundice unfit for surgery. A smaller diameter EC-LAMS should be preferred, particularly if the drainage is performed through the stomach, to avoid potential food impaction, which could result in stent dysfunction.

Abstract
BACKGROUND AND AIMS EUS-guided hepaticogastrostomy (EUS-HPG) has a risk of serious procedural adverse events (AEs), but few dedicated devices for EUS-HPG are available. We evaluated the feasibility of a new partially covered self-expandable metal stent (PCSEMS) with an anchoring flange for EUS-HPG. METHODS The feasibility of a stent featuring a proximal radiopaque uncovered portion 1.5 cm in length and a distal anchoring flange 20 mm in diameter was evaluated in consecutive patients undergoing EUS-HPG for unresectable malignant biliary obstruction. Primary outcomes were the technical and clinical success of EUS-HPG, and secondary outcomes were AEs, recurrent biliary obstruction (RBO), reintervention for RBO, and the technical feasibility of peroral cholangioscopy (POC) through the stent in situ. RESULTS EUS-HPG was performed in 24 patients with unresectable malignant biliary obstruction. The technical and clinical success rates of EUS-HPG were 100% (24/24) and 91.7% (22/24), respectively. AEs developed after EUS-HPG in 8.3% of patients (2/24, cholangitis). RBO developed in 29.2% of patients (7/24), with a median cumulative time to RBO of 6.7 months. The causes of RBO were sludge formation (n = 4), hyperplasia at an uncovered portion (n = 2), and nonocclusive cholangitis (n = 1). Reintervention for RBO had a 100% success rate (7/7), and POC through the stent in situ was technically feasible in 7 of 8 patients with a stent diameter of 10 mm. CONCLUSIONS EUS-HPG with a new PCSEMS can alleviate malignant biliary obstruction after failed ERCP. The novel stent evaluated in this study may prevent stent-related AEs, including stent migration, and allow advanced endoscopic interventions through the HPG route.

Abstract
Aims: Lumen-apposing metal stents (LAMSs) in ultrasonography-guided gallbladder drainage (EUS-GBD) have become increasingly important for high-risk surgical patients. Our study aims to evaluate the technical and clinical success, safety, and feasibility of endoscopic ultrasonography-guided gallbladder drainage using a new dedicated LAMS. Methods: This is a retrospective multicenter study that included all consecutive patients not suitable for surgery who were referred to a tertiary center for EUS-GBD using a new dedicated electrocautery LAMS for acute cholecystitis at eight different centers. Results: Our study included 54 patients with a mean age of 76.48 years (standard deviation: 12.6 years). Out of the 54 endoscopic gallbladder drainages performed, 24 (44.4%) were cholecysto-gastrostomy, and 30 (55.4%) were cholecysto-duodenostomy. The technical success of LAMS placement was 100%, and clinical success was achieved in 23 out of 30 patients (76.67%). Adverse events were observed in two patients (5.6%). Patients were discharged after a median of 5 days post-stenting. Conclusions: EUS-GBD represents a valuable option for high-surgical-risk patients with acute cholecystitis. This new dedicated LAMS has demonstrated a high rate of technical and clinical success, along with a high level of safety.

Abstract
BACKGROUND An electrocautery-enhanced delivery system with a lumen-apposing metal stent (LAMS) is available for one-step endoscopic ultrasound-guided transmural drainage (EUS-TD). Bipolar electrosurgery has several potential clinical advantages, including reduced collateral thermal damage, enhanced hemostasis, and no requirement for a return electrode plate. In this study, we compared the technical feasibility and safety of a newly developed bipolar electrocautery-enhanced delivery system with a conventional delivery system for EUS-TD using a LAMS in a porcine model. METHOD Ten days before the study, 12 mini pigs underwent common bile duct ligation for EUS-guided gallbladder drainage. Transenteric puncture was performed, followed by placement of a guidewire. In six pigs, a bipolar electrocautery-enhanced delivery system with LAMS (Hot SPAXUS) was inserted over the guidewire and advanced into the gallbladder, without prior dilation of the tract, by applying a bipolar cut current. In the remaining six pigs, a conventional delivery system with LAMS (Cold SPAXUS) was inserted after tract dilatation using a cystotome. The stent was removed after 4 weeks. RESULTS In all pigs, the stent was successfully inserted and deployed in the gallbladder without adverse events. The mean procedure time of EUS-TD was significantly lower in the Hot SPAXUS group than that of the Cold SPAXUS group (mean ± standard deviation: 188.7 ± 5.2 vs 449.5 ± 97.5 s, P = .0019). Stent migration was not observed, and all stents were removed successfully. CONCLUSIONS Endoscopic ultrasound-guided transmural drainage using a bipolar electrocautery-enhanced LAMS is feasible for reducing the procedure time while maintaining the high success rate and safety of conventional LAMS.

Abstract
BACKGROUND/PURPOSE Compared with currently available duodenoscopy-assisted systems, direct peroral cholangioscopy (DPOC) using an ultra-slim endoscope is limited by technical difficulties. The multibending (MB) ultra-slim endoscope was introduced as a dedicated cholangioscope for DPOC to challenge the technical problem. We retrospectively analyzed the clinical utility of DPOC using an MB endoscope with free-hand insertion into the bile duct in patients with biliary diseases. METHODS A total of 145 patients who underwent DPOC using an MB endoscope were analyzed. The primary outcome was the technical success rate of DPOC using the free-hand insertion of the MB endoscope. The secondary outcomes were the technical success rates of DPOC-guided diagnostic and therapeutic interventions, the diagnostic accuracy of DPOC-guided target biopsy, and adverse events related to DPOC. RESULTS Free-hand biliary insertion of a MB endoscope for DPOC was technically successful in 133 patients (91.7%). DPOC-guided target biopsy was successful in 36 of 38 patients (94.7%) and had a diagnostic accuracy of 91.7% (95% confidence interval, 82.6-100). Sixty-nine therapeutic interventions were performed; technical success was achieved in 65 (94.2%). No severe adverse events were observed. CONCLUSIONS The MB ultra-slim endoscope was technically effective to perform a DPOC including various diagnosis and therapeutic interventions without device assistance. MB endoscope is considered to contribute to expanding a role of DPOC in diagnosis and treatment of diverse biliary tract diseases.

Abstract
BACKGROUND AND AIMS Direct peroral cholangioscopy (POC) can be useful when combined with narrow-band imaging (NBI) to explore the etiologies of indeterminate biliary strictures. We evaluated the efficacy of NBI compared with that of conventional white-light imaging (WLI) during POC diagnosis of indeterminate biliary strictures. METHODS Consecutive patients with indeterminate biliary strictures were enrolled from 2016 to 2019. The primary outcome was diagnostic accuracy, and secondary outcomes were technical success, adverse events, and visualization quality when predicting malignancy. RESULTS Seventy-one patients underwent direct POC under NBI during targeted biopsy sampling. The strictures were successfully explored and adequate biopsy samples obtained in 67 of 71 patients (94.4%). In terms of visual impression, WLI and NBI afforded 75.0% and 87.5% sensitivity, 82.9 and 91.4% specificity, and 82.8 and 91.3% accuracy, respectively. The areas under the WLI and NBI receiver-operating characteristic curves were .80 and .96 (P = .01). Under NBI, the visualization quality of surface structures, microvessels, and lesional margins was higher than that under conventional WLI (P < .05). CONCLUSIONS Direct POC under NBI effectively and accurately predicts malignancies of indeterminate biliary strictures. NBI effectively illuminated surface structures, microvessels, and lesional margins.

Abstract
Background and study aims Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in malignant biliary obstruction (MBO) patients. Biliary drainage using electrocautery lumen apposing metal stent (EC-LAMS) is currently a well-established procedure when ERCP fails. We aimed to assess the technical and clinical success of a new EC-LAMS as the first approach to the palliation of malignant jaundice due to MBO in patients unfit for surgery. Patients and methods Twenty-five consecutive patients undergoing endoscopic-guided biliary drainage with the new EC-LAMS were prospectively enrolled. Clinical success was defined as bilirubin level decrease > 15 % 24 hours after EC-LAMS placement. Results Mean age was 76.6 ± 11.56 years, and male patients were 10 (40 %). EC-LAMS placement was technically feasible in 24 patients (96 %) and clinical success rate was 100 %. Only one patient (4 %) experienced a misplacement rescued by an immediate second EC-LAMS placement. The mean duration of hospital stay was 4.66 ± 4.22 days. The median overall survival was 7 months (95 % CI 1-7). Conclusions In this preliminary study, the new EC-LAMS seems to allow a single-step palliative endoscopic therapy in patients affected by jaundice due to MBO, with high technical and clinical success and low adverse events. Further large prospective studies are warranted to validate these results.

Abstract
Malignant hilar biliary obstruction (MHO), an aggressive perihilar biliary obstruction caused by cholangiocarcinoma, gallbladder cancer, or other metastatic malignancies, has a poor prognosis. Surgical resection is the only curative treatment method for biliary malignancies. However, most of the patients with MHO cannot undergo surgeries on presentation because of an advanced inoperable state or a poor performance state due to old age or comorbid diseases. Therefore, palliative biliary drainage is mandatory to improve symptomatic jaundice and quality of life. Among drainage methods, endoscopic biliary drainage is the current standard for the palliation of unresectable advanced MHO. The development of stents and various accessories and advances in endoscopic techniques including endoscopic ultrasonography have facilitated primary endoscopic intervention in difficult high-grade hilar strictures. However, some issues are still under debate, such as palliation methods, appropriate stents, the number of stents, deployment methods, and additional local ablation therapies. Therefore, this review presents currently optimal endoscopic palliation methods for advanced MHO based on the reported literature.

Abstract
BACKGROUND AND AIM The detection of residual or fragmented common bile duct (CBD) stones after lithotripsy can be improved by the high-resolution imaging quality of digital, single-operator cholangioscopy (SOC). However, therapeutic interventions for the removal of residual CBD stones are limited by the lack of appropriate tools. We retrospectively evaluated the role of SOC and the newly developed Dormia basket for the evaluation and removal of stones remaining after lithotripsy. METHODS Thirty-four patients who had undergone lithotripsy for retained CBD stones with no evidence of filling defects in occluded balloon cholangiography from March 2017 to October 2018 were included in the study. After balloon cholangiography, the bile duct was evaluated by SOC for complete evacuation of the stones. The detected residual CBD stones were directly retrieved by inserting the newly developed Dormia basket into the working channel of the SOC. The incidence of residual stones detected by SOC and the success rate of residual stone retrieval by SOC were investigated. RESULTS Digital SOC was successfully performed in all patients. Of these, 11 patients (32.4%) had residual CBD stones. The residual stones were successfully removed in 10 patients (90.9%) by SOC using the Dormia basket, except in one case of residual stones left in the hepatic duct. There were no adverse events associated with the SOC procedures or direct stone removal. CONCLUSIONS Digital SOC combined with the newly developed Dormia basket was useful for the detection and extraction of residual CBD stones under direct visualization after lithotripsy.

Abstract
BACKGROUND Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using a lumen-apposing metal stent (LAMS) has rendered endoscopic gallbladder assessment through a stent possible, but an appropriate endoscope is required. We assessed the feasibility of peroral cholecystoscopy (POCC) using a multibending ultraslim endoscope passed through a LAMS after EUS-GBD. METHODS 14 patients with a LAMS for EUS-GBD who consecutively underwent POCC were included. POCC was performed using a multibending endoscope inserted through the LAMS. The primary outcome was the technical success rate, defined as complete endoscopic examination of the gallbladder from the orifice of the cystic duct to the fundus. The types of intervention and adverse events were recorded. RESULTS 17 POCCs were performed in 14 patients. Of the 17 POCCs, 15 (88.2 %) were technically successful. Narrow-band imaging endoscopy was performed in 12 procedures (70.6 %), and cholecystoscopy-guided target biopsies were obtained in six. Gallstone extraction was performed in two patients. After POCC, all LAMSs remained stable and no adverse events were observed. CONCLUSIONS POCC using a multibending ultraslim endoscope can be effectively and safely performed through a LAMS after EUS-GBD.

Abstract
BACKGROUND AND AIM There is no clear data to compare the effectiveness and safety of bilateral stent-in-stent (SIS) or stent-by-stent (SBS) deployment for advanced malignant hilar obstruction (MHO). This meta-analysis was done to investigate clinical outcomes of these deployment methods. METHODS We did a literature search to identify studies that reported the clinical outcomes of bilateral metal stents in patients with advanced MHO. Weighed pooled rates (WPR) along with 95% confidence interval (95% CI) were calculated in order to compare outcomes including technical and clinical success, adverse events, and stent occlusion between the two groups. We conducted a meta-analysis using a random-effects model. RESULTS Five comparative studies with 250 patients, and 20 single-arm studies for the SIS or SBS method were eligible for the meta-analysis and systematic review. The bilateral SIS deployment had a significantly higher technical success rate than did SBS deployment (OR 6.43; 95% CI 1.08-38.09). There was no difference in the clinical success (OR 1.23; 95% CI 0.45-3.38), overall adverse events rates (OR 0.42; 95% CI 0.15-1.18), or overall occlusion rate (OR 1.55; 95% CI 0.89-2.70). As a single-armed group, WPR of technical success of the SIS and SBS groups was 96.4% and 89.6%, respectively. Clinical success was 97.5% and 98.3%. Overall, adverse events were 35.9% and 22.6%. Occlusion rates were 27.7% and 37.7%. CONCLUSIONS Although there was a lack of quality data and heterogeneity, bilateral SIS deployment had a higher technical feasibility than did the SBS method in patients with advanced MHO, without differences in terms of clinical success, adverse events, or occlusion rates.

Abstract
Background/Aims Treatment options for difficult bile duct stones are limited. Direct peroral cholangioscopy (POC)-guided lithotripsy may be an option. A newly developed multibending (MB) ultraslim endoscope has several structural features optimized for direct POC. We evaluated the utility of direct POC using an MB ultraslim endoscope for lithotripsy in patients with difficult bile duct stones. Methods Twenty patients with difficult bile duct stones, in whom stone removal using conventional endoscopic methods, including mechanical lithotripsy, had failed were enrolled from March 2018 to August 2019. Direct POC-guided lithotripsy was performed by electrohydraulic lithotripsy or laser lithotripsy. The primary outcome was complete ductal clearance, defined as the retrieval of all bile duct stones after lithotripsy confirmed by balloon-occluded cholangiography and/or direct POC. Results The technical success rate of direct POC was 100% (20/20), and the free-hand insertion rate was 95% (19/20). Direct POC-guided lithotripsy, attempted by electrohydraulic lithotripsy in nine patients (45%) and laser lithotripsy in 11 patients (55%), was successful in 95% (19/20) of the patients. Complete ductal clearance after direct POC-guided lithotripsy was achieved in 95% (19/20) of patients. Patients required a median of 2 (range, 1-3) endoscopic retrograde cholangiopancreatography sessions for complete stone removal. Adverse event was observed in one patient (5%) with hemobilia and was treated conservatively. Conclusions Direct POC using an MB ultraslim endoscope was safe and effective for lithotripsy in patients with difficult bile duct stones.

Abstract
BACKGROUND AND AIM Durable biliary drainage is essential in patients with pancreatic cancer in the era of effective neoadjuvant chemotherapy (NACT). Plastic stent (PS) tends to occlude easily, and current metal stents are designed for nonresectable cancer. We evaluated the efficacy of a modified non-flared fully covered self-expandable metal stent (M-FCSEMS) during the perioperative period in patients with resectable or borderline resectable pancreatic cancer. METHODS Consecutive patients with resectable or borderline resectable pancreatic ductal adenocarcinoma had a 12-mm M-FCSEMS (M-FCSEMS group) or 7-Fr PS (PS group) placed for biliary decompression before NACT or curative-intent surgery. The primary outcome was the re-intervention rate, and secondary outcomes were technical success, stent patency, and adverse events (AEs). RESULTS Endoscopic stent placement was technically successful in all 60 patients. Twenty-three patients underwent surgery and 37 NACT before surgery. Re-intervention was performed in 10.0% (3/30) of patients in the M-FCSEMS group and 36.7% (11/30) of patients in the PS group (P = 0.030). The stent patency at 180 days was 89.8% (95% confidence interval, 77.3-100.0%) in the M-FCSEMS group and 30.2% (95% confidence interval, 11.4-80.0%) in the PS group (P < 0.0001). Stent-related AEs occurred in 10.0% (3/30) in the M-FCSEMS group and 40.0% (12/30) in the PS group (P = 0.015). Surgery-related AEs occurred in 10.5% (2/19) and 14.3% (3/21) in the M-FCSEMS and PS groups (P = 0.549). CONCLUSIONS Modified non-flared fully covered self-expandable metal stents are effective and safe for durable biliary drainage in patients with resectable or borderline resectable pancreatic cancer during the perioperative period.

Abstract
BACKGROUND Long-term placement of lumen apposing metal stents (LAMS) with high lumen apposing force may result in adverse events. The aim of the current study was to assess the long-term efficacy and safety of a self-approximating LAMS with lower lumen apposing force for endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) and -gallbladder drainage (EUS-GBD). METHODS Five Asian institutions participated in this study. Consecutive patients suffering from obstructive jaundice with failed ERCP or acute cholecystitis that were at high risk for cholecystectomy were recruited. We evaluated the technical and clinical success rates, adverse events rates, types of interventions through the stent and the patency profile. RESULTS From June 2017 to Oct 2018, a total of 53 patients received EUS-CDS (26) and EUS-GBD (27). The technical and clinical success rates were similar between the two groups (88.5% vs 88.9%, P = 1 and 88.5% vs 88.9%, P = 1 respectively). The differences in 30-day mortality rates [2 (7.7%) vs 2 (7.7%), P = 1] and adverse events [3 (11.5%) vs 3 (11.5%), P = 1] did not reach significance. Regarding long-term outcomes, two patients in each group suffered from adverse events (P = 1). One patient in the EUS-GBD group who was on direct oral anticoagulant suffered from stent induced bleeding. CONCLUSION The self-approximating LAMS with lower lumen apposing force was effective and safe with a low risk of buried stent syndrome and bleeding in the longer term. The ClinicalTrials.gov Identifier was NCT03002051.

Abstract
The therapeutic utility of peroral cholangioscopy (POC) is limited. Direct POC using an ultra‑slim upper endoscope expands the therapeutic indications because of its larger working channel, of up to 2.2 mm. We evaluated the feasibility of selective biliary drainage using a plastic stent under direct POC. From April 2015 to March 2019, biliary drainage under endoscopic visualization was performed in the same endoscopic session as direct POC without exchanging the duodenoscope. After guidewire insertion through the stricture or stone, a 5 Fr plastic stent and/or nasobiliary drainage catheter was used for biliary drainage. Selective biliary drainage under direct POC was performed in 32 patients, including 17 with difficult bile duct stones. Biliary drainage was performed with a plastic stent in 29 patients, nasobiliary drainage in one, and combined drainage in two patients. The technical success rate for biliary drainage placement under direct POC was 100 % (32/32). No significant procedure-related complications occurred. In conclusion, biliary drainage with a plastic stent or catheter under direct POC using an ultra-slim upper endoscope is feasible and may be useful for lesions obstructing the bile duct.

Abstract
BACKGROUND The use of a lumen-apposing metal stent (LAMS) capable of one-step endoscopic ultrasound-guided transmural drainage (EUS-TD) can increase the effectiveness of the procedure. We evaluated the newly developed electrocautery-enhanced (EC) delivery system with a LAMS for one-step EUS-guided gallbladder drainage (EUS-GBD) or choledochoduodenostomy (EUS-CDS). METHODS In the animal experiment, an EC-LAMS was advanced into the gallbladder without prior tract dilation in four pigs. A conventional LAMS was inserted in another four pigs as a control group. After the animal experiment, 17 patients underwent EUS-TD using the EC-LAMS (EUS-GBD in 10 patients, EUS-CDS in 7). The primary outcome was the technical success rate. RESULTS In the animal study, the mean procedure time was significantly shorter in the EC-LAMS group than in the conventional LAMS group. In the human study, the overall technical success rate was 94.1 %, with one EUS-GBD failure. The clinical success rate was 100 %. The overall adverse event rate was 17.6 %. CONCLUSIONS One-step EUS-GBD or EUS-CDS using the novel EC-LAMS is a feasible approach that achieves a high success rate and maintains safety.

Abstract
Malignant hilar obstruction (MHO) is considered an aggressive perihilar obstruction caused by cholangiocarcinoma, gallbladder cancer, or metastatic malignancies and has a poor prognosis. Although surgical resection is the only curative treatment method, the majority of patients with MHO do not undergo surgery due to an advanced inoperable state at presentation. Currently, effective biliary drainage provides the necessary palliation for symptomatic improvement. Among the drainage methods, percutaneous access may be preferred, especially for advanced MHO because of the technical difficulty involved with other techniques. Recently, primary endoscopic palliation using plastic or metal stents has been shown to have higher technical feasibility and clinical success without increasing adverse events even in patients with high-degree MHO. The development of various accessories, endoscopic ultrasonography, and advances in techniques have facilitated primary endoscopic intervention. However, some aspects continue to be debated such as the palliation methods, appropriate stents, the number of stents, the deployment methods, and additional local ablation therapies. Therefore, this review discusses the current optimal endoscopic treatment methods for advanced MHO based on reported literature.

Abstract
PURPOSE Erlotinib has been the only targeted agent to show significantly improved outcomes in pancreatic adenocarcinoma when combined with gemcitabine. We aimed to evaluate whether the addition of oxaliplatin to a combination gemcitabine/erlotinib treatment conferred a clinical benefit in patients with locally advanced unresectable or metastatic pancreatic cancer. MATERIALS AND METHODS Chemotherapy-naïve patients with locally advanced or metastatic pancreatic cancer were randomly assigned to receive GEMOX-T [gemcitabine 1000 mg/m² and oxaliplatin 50 mg/m² on day 1 (D1) and D8 plus erlotinib 100 mg daily for 3 weeks] or GT (gemcitabine 1000 mg/m² on D1 and D8 plus erlotinib 100 mg daily for 3 weeks). The primary endpoint was the overall response rate (ORR). RESULTS Between 2013 and 2016, 65 patients were assigned to a treatment group (33 in the GEMOX-T arm, 32 in the GT arm). The ORR was 18.2% [95% confidence interval (CI), 8.82-27.58] in the GEMOX-T arm and 6.2% (95% CI, 0.34-12.06) in the GT arm (p=0.051). The disease control rate was significantly superior in the GEMOX-T arm compared to the GT arm (72.7% vs. 43.8%, p=0.019). After a median follow-up of 19.7 months, the median progression-free survival (PFS) was 3.9 months for the GEMOX-T arm and 1.4 months for the GT arm (p=0.033). However, this did not translate to an improvement in overall survival. The most common grade 3 or higher hematologic adverse events were neutropenia (16.9%) and anemia (13.8%). CONCLUSION The addition of oxaliplatin to a first-line gemcitabine/erlotinib regimen demonstrated higher response rates and significantly improved PFS in patients with locally advanced or metastatic pancreatic cancer.

Abstract
The purpose of this study was to determine the glucose metabolism at delay phase measured by pretreatment dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/ computed tomography (CT) provides prognostic information independent of well-known prognostic factors in patients with intrahepatic or perihilar cholangiocarcinoma (ICC or PCC).From July 2012 to December 2017, 55 patients (men 27, women 28, mean age 68 ± 11 years) with pathologically proven ICC or PCC were enrolled in this retrospective study. The dual-time-point 18F-FDG PET/CT as part of a staging workup was performed in all patients. The patient's data includes age, sex, serum CA19-9, presence of LN or distant metastasis, early SUVmax (early maximum standardized uptake value [eSUV]), delay SUVmax (delay maximum standardized uptake value [dSUV]), retention index of SUVmax (percent change of maximum standardized uptake values [ΔSUV]), neutrophil to lymphocyte ratio (NLR) and histopathology including pCEA, p53, Ki-67 index. The analysis of the relationship between metabolic parameters and survival was done using the Kaplan-Meier curve and Cox proportional hazards regression model.Median survival for all patients was 357 days. Median early and delay SUVmax was 5.2 (range: 2.0-21.4) and 6.5 (range 2.7-24.5), respectively. The overall survival was found to be significantly related to eSUV, dSUV, ΔSUV, age, serum CA19-9 and NLR in univariate analysis. In multivariate analysis, dSUV (P = .014, 95%CI; 1.30-10.7, HR 3.74) and ΔSUVmax (P = .037, 95%CI; 1.05-6.12, HR 2.5) were independent factors of overall survival. Kaplan-Meier curve analysis clearly showed the significant difference of overall survival between 2 groups (high eSUV, low eSUV + high ΔSUV vs low eSUV and ΔSUV, P < .001) among the comparisons of the SUV parameters on FDG PET. In the receiver operating characteristic analysis using combinations of the SUV parameters, the 2 groups [eSUV + ΔSUV (P = .0001, area under the curve [AUC] 0.68) and dSUV + ΔSUV (P = .0002, AUC 0.71)] showed significantly larger AUC than the other groups applying eSUV or dSUV alone (AUC 0.61 and AUC 0.68).dSUV and ΔSUV on pretreatment dual-time-point 18F-FDG PET/CT can be useful parameters in the prediction of survival in patients with ICC or PCC.

Abstract
BACKGROUND AND AIM Endoscopic management of a benign biliary stricture (BBS) on the hilum is complicated and challenging. Although the placement of a fully covered self-expandable metal stent (FCSEMS) is possible to increase effectiveness, stent migration and stent-induced adverse events are problematic. We aimed to evaluate the usefulness of a modified short FCSEMS with a long lasso in patients with a difficult perihilar BBS. METHODS Patients with perihilar BBS within 2 cm from the hilar confluence that failed initially with plastic stents were enrolled. A modified short FCSEMS was deployed and then removed 5-6 months later. The primary outcome was clinical success. Other technical success, adverse events, endoscopic success of stent removal, and recurrence of stricture during the follow-up period were measured. RESULTS Endoscopic intraductal placement was technically successful in all patients (n = 19). Combined contralateral plastic stent placement was performed in 13 patients (68.4%). The median duration of stent placement was 163 days (range, 138-196 days). Endoscopic stent removal was successful in all patients except one spontaneous distal migration. Stricture resolution without de novo focal stricture occurrence was 100%. Endoscopic stone removal after stricture improvement was successful in all 13 patients with bile duct stones above the stricture. During a follow-up period (median 635 days) after stent removal, only one recurrence developed. CONCLUSIONS Temporary placement of a modified intraductal short FCSEMS with or without a contralateral plastic stent improved perihilar BBS in patients that primarily failed by plastic stents. Combined biliary stones were also successfully removed after stricture resolution.

Abstract
BACKGROUND AND AIM Endoscopic post-papillectomy bleeding occurs in 3% to 20% of the cases, and delayed bleeding is also problematic. However, there is no consensus on how to reduce delayed post-papillectomy bleeding. The aim of this study was to evaluate the efficacy of prophylactic argon plasma coagulation (APC) to minimize delayed bleeding and reduce the persistence of residual tumors after endoscopic papillectomy. METHODS In a prospective pilot study of patients with benign ampullary tumors, the prophylactic APC group underwent APC at the resection margin following a conventional snaring papillectomy. Then, 24 h later after the papillectomy, all patients underwent a follow-up duodenoscopy to identify post-papillectomy bleeding and were followed up until 12 months. The main outcomes were the delayed (≥24 h) post-papillectomy bleeding rate and the tumor persistence rate. RESULTS The delayed post-papillectomy bleeding rate was 30.8% (8/26) in the prophylactic APC group and 21.4% (6/28) in the non-APC group (P = 0.434). The post-procedure pancreatitis rates were 23.1% (6/26) and 35.7% (10/28), respectively (P = 0.310). The rate of tumor persistence did not differ between the two groups at 1 month (12.5% vs 7.4%, P = 0.656), 3 months (4.2% vs 3.7%, P = 1.00), 6 months (8.3% vs 3.7%, P = 0.595), and 12 months (0% vs 3.7%, P = 1.00). There were no procedure-related mortalities or serious complications. CONCLUSION Prophylactic APC may not be effective in reducing delayed post-papillectomy bleeding or remnant tumor ablation immediately after conventional papillectomy (Clinical trial registration-cris.nih.go.kr; KCT0001955).

Abstract
BACKGROUNDS AND AIM Multiple insertions of self-expandable metal stents (SEMS) for advanced malignant hilar obstruction (MHO) are now considered to be an effective palliative method for adequate drainage of liver volume. However, the efficacy of endoscopic reintervention in technically and clinically successful bilateral SEMS is limited. This study investigated the endoscopic revision efficacy in patients who underwent bilateral SEMS in MHO. METHODS Primary endoscopic revision using plastic or metal stents or an alternative percutaneous approach followed by secondary endoscopic revision was performed in patients who underwent clinically successful deployment of bilateral SEMS. The primary outcome was a technical success. Secondary outcomes were clinical success, adverse events, and patency duration after reintervention. RESULTS A total of 55 patients (83.3%) out of 66 enrolled patients underwent reintervention: primary endoscopic reintervention (n = 47) and secondary endoscopic revision following percutaneous drainage (n = 8). Intended technical success rates of primary and secondary endoscopic reintervention were 93.6% (44/47) and 87.5% (7/8), respectively (P = 0.47). Clinical success rates were 72.3% and 50%, respectively (P = 0.23). Stent malfunction rate after reintervention was 48.9% (23/47) and 37.5% (3/8) (P = 0.70) during follow up, and median cumulative stent patency duration was 119 and 55 days, respectively (log-rank P = 0.68). Stent patent rate after reintervention was not different according to the time interval. In univariate and multivariate analysis for stent patency duration-related factors after reintervention, there were no meaningful factors. CONCLUSION Primary endoscopic reintervention for bilateral SEMS in MHO was feasible technically and clinically. However, there were no statistically meaningful factors for stent patency duration after reintervention.

Abstract
BACKGROUND Peroral cholangioscopy (POCS) of indeterminate biliary strictures aims to achieve a diagnosis through visual examination and/or by obtaining targeted biopsies under direct visualization. In this large, prospective, multinational, real-life experience of POCS-guided evaluation of indeterminate biliary strictures, we evaluated the performance of POCS in this difficult-to-manage patient population. METHODS This prospective registry enrolled patients, with indeterminate biliary strictures across 20 centers in Asia, the Middle East, and Africa. The primary end points were the ability to visualize the lesion, obtain histological sampling when intended, and an assessment of the diagnostic accuracy of POCS for malignant strictures. Patients were followed for 6 months after POCS or until a definitive malignant diagnosis was made, whichever occurred first. RESULTS 289 patients underwent 290 POCS procedures with intent to biopsy in 182 cases. The stricture/filling defect was successfully visualized in 286/290 (98.6 %), providing a visual diagnostic impression in 253/290 (87.2 %) and obtaining adequate biopsies in 169/182 (92.9 %). Procedure-related adverse events occurred in 5/289 patients (1.7 %). POCS influenced patient management principally by elucidating filling defects or the causes of bile duct stricture or dilation. The visual impression of malignancy showed 86.7 % sensitivity, 71.2 % specificity, 65.8 % positive and 89.4 % negative predictive value, and 77.2 % overall accuracy compared with final diagnosis. Histological POCS-guided samples showed 75.3 % sensitivity, 100 % specificity, 100 % positive and 77.1 % negative predictive value, and 86.5 % overall accuracy. CONCLUSION In this large, real-life, prospective series, POCS was demonstrated to be an effective and safe intervention guiding the management of patients with indeterminate biliary strictures.

Abstract
Distal biliary strictures (DBS) are common and may be caused by both malignant and benign pathologies. While endoscopic procedures play a major role in their management, a comprehensive review of the subject is still lacking. Our consensus statements were formulated by a group of expert Asian pancreatico-biliary interventional endoscopists, following a proposal from the Digestive Endoscopy Society of Taiwan, the Thai Association for Gastrointestinal Endoscopy, and the Tokyo Conference of Asian Pancreato-biliary Interventional Endoscopy. Based on a literature review utilizing Medline, Cochrane library, and Embase databases, a total of 19 consensus statements on DBS were made on diagnosis, endoscopic drainage, benign biliary stricture, malignant biliary stricture, and management of recurrent biliary obstruction and other complications. Our consensus statements provide comprehensive guidance for the endoscopic management of DBS.

Abstract
AIM To assess the predictive value of preoperative residual mammographic microcalcifications for residual tumours after neoadjuvant chemotherapy (NAC) for breast cancer. MATERIALS AND METHODS This single-centre retrospective study included breast cancer patients who underwent NAC and demonstrated suspicious microcalcifications within or near the tumour bed on mammography from June 2015 to August 2018. The residual microcalcifications and remnant lesion on magnetic resonance imaging (MRI) were correlated with histopathological findings of residual tumours and immunohistochemical markers. RESULTS A total of 96 patients were included. Ten patients achieved pathological complete response (pCR) and previous suspicious microcalcifications were associated with benign pathology in 10.4% (10/96) of the patients. In the remaining 86 patients who did not achieve pCR, 61.5% (59/96) of the residual microcalcifications were associated with invasive or in situ carcinoma and 28.1% (27/96) with benign pathology. Hormone receptor-positive (HR+) patients had the highest proportion of residual malignant microcalcifications compared to HR- patients (48.9% versus 13.5%, respectively; p=0.019). MRI correlated better than residual microcalcifications on mammography in predicting residual tumour extent in all subtypes (ICC=0.709 versus 0.365). MRI also showed higher correlation with residual tumour size for the HR-/HER2+ and HR-/HER2- subtype (ICC=0.925 and 0.876, respectively). CONCLUSION The extent of microcalcifications on mammography after NAC did not correlate with the extent of residual cancer in 38.5% of women. Regardless of the extent of microcalcifications, residual tumour extent on MRI after NAC and molecular subtype could be an accurate tool in evaluating residual cancer after NAC.

Abstract
BACKGROUND AND AIMS Fully covered self-expanding metal stents (FCSEMSs) are considered to be more effective than plastic stents for the treatment of main pancreatic duct (MPD) strictures associated with chronic pancreatitis (CP) because of their larger diameter and exertion of a radial expansion force. However, the current FCSEMSs have several limitations. To overcome these, a novel modified nonflared FCSEMS was developed. In this study we conducted a prospective long-term follow-up evaluation of the efficacy of the novel FCSEMS for the treatment of refractory benign PD strictures in patients with CP. METHODS Consecutive patients with symptomatic CP associated with refractory MPD strictures were enrolled prospectively in this single-arm study. The nonflared FCSEMS was placed intraductally or transpapillary according to the location and length of the stricture. Stent removal was performed at 3 months after placement. The primary outcome was the resolution of the pancreatic ductal stricture. RESULTS Endoscopic placement of modified nonflared FCSEMSs was technically successful in all 25 patients. Intraductal FCSEMS placement was performed in 14 patients (56.0%). Stents of diameter 8 mm were used in 17 patients (68.0%). Stents of lengths 3 and 5 cm were inserted in 22 (88.0%) and 3 (12.0%) patients, respectively. In 1 patient (4.0%), stent migration developed. All other stents were removed successfully. After stent removal, resolution of the MPD stricture was confirmed in all patients, and no FCSEMS-related de novo stricture was observed. During the follow-up period (median, 34 months; interquartile range, 25-56) after the stents had been removed from the 25 patients, reintervention for recurrence of MPD stricture with abdominal pain was performed in 2 patients (8.0%). CONCLUSIONS Endoscopic placement of a novel modified nonflared FCSEMS resulted in long-term stricture resolution with pain relief and reduced the rate of stent-related adverse events, particularly stent migration and stent-induced de novo MPD stricture.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using an anti-migrating tubular self-expandable metal stent (ATSEMS) is performed in high surgical risk patients with acute cholecystitis. The newly introduced lumen-apposing metal stent (LAMS) is expected to reduce the risk of tubular self-expandable metal stent-related adverse events such as stent migration, but no comparative studies have been carried out between LAMSs and ATSEMSs for EUS-GBD. METHODS We reviewed the prospectively collected EUS-GBD database at Asan Medical Center and Bucheon Soonchunhyang hospital to analyze consecutive patients with acute cholecystitis who underwent EUS-GBD with LAMSs or ATSEMSs between January 2015 and December 2017. Technical success, clinical success, adverse events, and recurrence of cholecystitis were evaluated. RESULTS A total of 71 patients (36 with LAMSs, 35 with ATSEMSs) were analyzed. The LAMS group had longer median procedure time (15.5 minutes) than the ATSEMS group (11 minutes; P = .017). The 2 groups did not show significant differences in terms of technical success (LAMS, 94% vs ATSEMS, 100%; P = .49), clinical success (94% vs 100%; P = .49), procedure-related adverse events (0% vs 2.9%; P = .99), and stent-related late adverse events (11.8% vs 5.8%; P = .43). During follow-up, the 2 groups had similar rates of cholecystitis recurrence at 6 months (LAMS, 3.4% vs ATSEMS, 3.1%, P = .99) and 12 months (8.3% vs 3.1%, P = .56). CONCLUSIONS In high surgical risk patients with acute cholecystitis, LAMSs and ATSEMSs for EUS-GBD showed similar rates of technical success, clinical success, procedure-related adverse events, stent-related late adverse events, and recurrence of cholecystitis.

Abstract
BACKGROUND AND AIM Fully covered self-expandable metallic stent (FCSEMS) may be an effective modality for managing anastomotic biliary stricture (ABS) after liver transplantation. However, stent migration and stent-induced ductal injury are the main limitations. The objective of this study was to evaluate the usefulness of an unflared, intraductal FCSEMS that was designed to minimize migration and ductal injury for refractory ABS after living donor liver transplantation (LDLT). METHODS A total of 32 consecutive patients with symptomatic ABS after LDLT unresolved by plastic stents with or without balloon dilation at four tertiary medical centers were prospectively enrolled. A short (3 or 5 cm) FCSEMS having long lasso (10 cm) used in this study had unflared convex ends to minimize tissue hyperplasia and smaller center portion to prevent migration. The FCSEMS was placed above the papilla and removed at 3-4 months after stenting. RESULTS Technical and clinical success rates of intraductal placement with FCSEMS were 100% (32/32) and 81.2% (26/32), respectively. Early stent migration was observed in five (15.6%) patients. However, three patients with early stent migration had stricture resolution without needing additional intervention. Intended stent removal was successful in 27 (100%) patients (median, 101 days; range, 23-118 days). No stent-induced ductal change was observed in all patients. Stricture recurrence was observed in 11.5% (3/26) of patients during 639 days of median duration of follow-up (range, 366-2079 days). CONCLUSIONS Intraductal placement of an unflared short FCSEMS may be a promising option for refractory ABS after LDLT with minimal stent-induced ductal injury and stent migration.

Abstract
BACKGROUND A novel self-approximating lumen-apposing metallic stent (LAMS; Niti-S Spaxus, Taewoong Medical, Gyeonggi-do, Korea) has recently become available. The aim of the present study was to evaluate the outcomes for drainage of pancreatic fluid collections (PFC). METHODS This was a prospective international multicentered study conducted in six high-volume institutions across Asia. Consecutive patients suffering from pancreatic pseudocyst or walled-off pancreatic necrosis (WOPN) requiring endoscopic ultrasonography-guided drainage were recruited. Outcomes included technical and clinical success, adverse events, procedural events, interventions through the stent and recurrence rates. RESULTS Between August 2016 and November 2017, 59 patients were recruited to this study. Thirty-nine patients (66.1%) had WOPN and mean (SD) size of PFC was 11.5 (5.1) cm. Technical and clinical success rates were 100%. Mean (SD) procedural time was 35.0 (17.2) minutes. Sixteen-millimeter stents were used in 66.1% of the patients. Fifty-four sessions of necrosectomy were carried out with the stent in situ in 17 patients. Stent-related adverse event (AE) rate was 6.8%. Three patients (5.1%) suffered from bleeding after stenting and one required angiographic embolization. Two patients (3.4%) suffered from recurrence during a mean (SD) follow-up time of 325.6 (355.5) days. There were no differences in outcomes between those with pseudocysts or WOPN except for the duration of hospital stay (P = 0.012). CONCLUSION Use of a self-approximating LAMS for drainage of PFC was safe and effective. Endoscopic necrosectomy could be carried out through the stent with ease. The device was associated with a low rate of stent-related AE.

Abstract
BACKGROUND AND AIMS Currently available peroral cholangioscopy (POC) is a duodenoscopy-assisted procedure that does not involve directly inserting an endoscope into the biliary tree. A prototype multibending (MB) ultra-slim endoscope has been developed as a dedicated cholangioscope to overcome the technical difficulties of direct POC. In this study, we evaluated the efficacy of the new MB ultra-slim endoscope compared with a conventional ultra-slim endoscope for free-hand insertion of an endoscope into the bile duct for direct POC without the assistance of accessories. METHODS Ninety-two patients with biliary disease requiring diagnostic and/or therapeutic direct POC were assigned randomly to groups examined using an MB ultra-slim endoscope (MB group, n=46) versus a conventional ultra-slim endoscope (conventional group, n=46). The primary outcome was the technical success of free-hand insertion of the endoscope during direct POC, defined as successful insertion of the endoscope through the ampulla of Vater and advancement of the endoscope up to the bifurcation or to the obstructed segment of the biliary tree without any accessories within 15 minutes. RESULTS Free-hand biliary insertion of the endoscope for direct POC was technically successful in 41 patients (89.1%) in the MB group, which was significantly higher than the rate (14 patients, 30.4%) in the conventional group (P < .001). The procedure time (mean ± standard deviation) of direct POC using free-hand biliary insertion of the endoscope was significantly shorter in the MB group than in the conventional group (3.2 ± 1.8 vs 6.0 ± 3.0 minutes, P = .004). Adverse events were observed in 3 patients (6.5%) in the MB group and 2 patients (4.3%) in the conventional group (P = .500), all of whom were treated conservatively. The technical success rates of the diagnostic or therapeutic intervention were not significantly different between the 2 groups in patients undergoing successful direct POC. CONCLUSIONS Free-hand biliary insertion of the MB ultra-slim endoscope showed a high technical success rate without severe adverse events and effectively decreased procedure time compared with a conventional ultra-slim endoscope. Direct POC using the MB ultra-slim endoscope can be used for novel diagnostic and therapeutic procedures of the biliary tree without the assistance of another endoscope or accessory.

Abstract
Although endoscopic intervention is the mainstay for palliation of malignant biliary obstruction, a percutaneous approach has been preferred, particularly in patients with advanced high-grade hilar malignant biliary obstruction, because of the technical difficulty and risk of complications. However, recently, primary endoscopic palliation using plastic or metal stents has had higher technical and clinical success with fewer adverse events than the percutaneous approach. Endoscopic interventions are being done more and more frequently because of advances in metal stents, accessories, and techniques. However, several concerns, such as optimal stent type, number, and deployment method, remain to be resolved. Therefore, we reviewed the literature in order to identify the optimal biliary stenting strategy for patients with hilar malignant biliary obstruction, focusing on stent type (plastic vs metal), number (unilateral [single] vs bilateral [multiple]), and deployment method (stent-in-stent vs stent-by-stent).

Abstract
Nasopharyngeal carcinoma (NPC) is a rare form of the head and neck cancer of the epithelial lining of the nasopharynx and exhibits the highest metastatic rate among head and neck cancers. Underlying mechanisms of metastasis remain largely unknown. Here, we explored whether Notch1 affects the invasion and metastasis of NPC cells. In vitro migration and invasion capacities were evaluated after the knockdown of Notch1 expression in NPC cells. To investigate the role of Notch1 in in vivo metastasis, we examined the metastatic ability to the lungs following administration of cancer cells via mouse tail vein. The expression of epithelial-mesenchymal transition (EMT) markers associated with Notch1-mediated metastasis was investigated, and their roles in metastasis and relationship with Notch1 expression were investigated. Suppression of Notch1 expression increased the ability of NPC cells to invade Matrigel in vitro. Knockdown of Notch1 expression in NPC cells resulted in extensive lung metastasis in a mouse model and increased the mRNA expression of Slug in NPC cells. Slug-specific RNA interference resulted in the loss of the metastatic and invasion capacities in Notch1-suppressed NPC cells. These findings show that Notch1 has a significant suppressive role in the regulation of metastasis in NPCs, suggestive of its prudent use in clinical trials.

Abstract
BACKGROUND Peroral cholangioscopy (POCS) can be useful for difficult bile duct stone clearance. Large prospective multinational data on POCS-guided lithotripsy for clearing difficult bile duct stones in a single session of endoscopic retrograde cholangiopancreatography (ERCP) are missing. METHODS Patients with difficult bile duct stones (defined as one or more of: largest stone diameter ≥ 15 mm, failed prior attempt at stone clearance, impacted, multiple, hepatic duct location, or located above a stricture) were enrolled at 17 centers in 10 countries. The principal endpoint was stone clearance in a single ERCP procedure using POCS. RESULTS : 156 patients underwent 174 sessions of POCS-guided electrohydraulic or laser lithotripsy. Stone clearance had failed in a previous ERCP using traditional techniques in 124/156 patients (80 %), while 32 /156 patients (21 %) were referred directly to POCS-guided therapy based on preprocedural assessment of the difficulty of stone clearance. In 101/156 patients (65 %), there were impacted stones. POCS-guided stone clearance was achieved in a single POCS procedure in 125 /156 patients (80 %, 95 % confidence interval [CI] 73 % - 86 %), and was significantly more likely for stones ≤ 30 mm compared with > 30 mm (odds ratio 7.9, 95 %CI 2.4 - 26.2; P = 0.002). Serious adverse events occurred in 3/156 patients (1.9 %, 95 %CI 0.4 % - 5.5 %), and included pancreatitis, perforation due to laser lithotripsy, and cholangitis (n = 1 each), all resolved within 1 week. CONCLUSION POCS-guided lithotripsy is highly effective for clearance of difficult bile duct stones in a single procedure and successfully salvages most prior treatment failures. It may also be considered first-line therapy for patients with difficult choledocholithiasis to avoid serial procedures.

Abstract
AbstractPeroral cholangioscopy (POC) provides direct visualization of the bile duct and facilitates diagnostic or therapeutic intervention. The currently available single-operator POC systems are “Mother-baby” scope system, SpyGlass direct visualization system, and direct POC using a regular ultra-slim upper endoscope. Direct POC using an ultra-slim upper endoscope having a larger 2-mm working channel can provide a valuable and economic solution for evaluating bile-duct lesions. Main diagnostic procedures under direct POC are visual characterization and optically guided target biopsy for the indeterminate bile duct lesion. Image-enhanced endoscopy such as narrow-band imaging has shown promise for more detailed evaluation of mucosal abnormality and can be performed under direct POC. Intracorporeal lithotripsy such as electrohydraulic lithotripsy or laser lithotripsy is a main therapeutic intervention of direct POC for patients with bile duct stones that are resistant to conventional endoscopic stone-removal procedures. Besides, tumor ablation therapy, such as photodynamic therapy and argon plasma coagulation may be also performed using direct POC. Further developments of the endoscope and specialized accessories or devices are expected to facilitate diagnostic and therapeutic role of this cholangioscopic procedure.

Abstract
Cholangioscopy provides an opportunity to directly visualize the bile duct for diagnosing biliary lesions and for therapeutic interventions. Although there are different cholangioscopy techniques available, single-operator cholangioscopy has gained widespread acceptance as the standard technique for interventions in the biliary system because of its ease of use and widespread availability. Single-operator cholangioscopy can be used for both diagnostic and therapeutic indications in the biliary tract. Diagnostic cholangioscopy is used for direct evaluation of indeterminate bile duct strictures with biopsies, diagnosing filling defects in the bile ducts observed during endoscopic retrograde cholangiography (ERC) imaging, preoperative mapping of the precise location and extension of tumors of the biliary tract, and diagnosis of intraductal neoplasms. Therapeutic cholangioscopy is used for visually guided treatment of biliary stones that have failed extraction with conventional ERC techniques, residual or impacted stones by using intraductal lithotripsy, ablation of biliary tumors and for facilitation of guidewire advancement into selective intrahepatic ducts for adequate biliary drainage. In this review, we will focus on advances in the single-operator cholangioscopy techniques in the diagnosis and management of biliary disorders.

Abstract
BACKGROUND AND AIMS Recently, a newly designed lumen-apposing metal stent (LAMS) with a conventional delivery system was developed. The purpose of this study was to evaluate the effectiveness and safety of a newly designed LAMS for EUS-guided drainage to treat symptomatic pancreatic pseudocysts. METHODS This prospective multicenter cohort study included 34 patients with symptomatic pancreatic pseudocysts from 2016 to 2017. The patients underwent EUS-guided drainage with the newly designed LAMS (Niti-S SPAXUS; Taewoong Medical Co, Ltd, Ilsan, South Korea). Effectiveness outcome measurements included technical success rate, clinical success rate, successful stent removal rate, and procedural time. Safety outcome measurements included procedure and/or stent-related adverse events (AEs) and overall AEs. Patients were prospectively followed, and consecutive data were collected at discharge, at stent removal, and 20 days after stent removal. RESULTS Thirty-four patients (mean age 51.7 ± 13.3 years, 26 men) were enrolled. The mean pseudocyst size was 9.23 ± 3.54 cm. The technical success rate was 97.1% (33/34). The clinical success rate was 94.1% (32/34). All stents were successfully removed. The mean procedural time from needle puncture to stent deployment was 10.3 ± 5.7 minutes. Four patients (11.8%) experienced procedure and/or stent-related AEs, including stent maldeployment (n = 1) and pseudocyst infection (n = 3). All patients completely recovered from the AEs. Bleeding caused by the stent or buried LAMS syndrome was not observed. No unplanned endoscopic procedures were required. CONCLUSIONS This study showed that EUS-guided drainage using the newly designed LAMS is technically feasible and effective for the treatment of symptomatic pancreatic pseudocysts. (Clinical trial registration number: NCT02730663.).

Abstract
BACKGROUND AND AIM Fully covered self-expandable metal stents (FCSEMS) may be better than plastic stents (PS) for preoperative biliary drainage (PBD) to relieve cholangitis or jaundice for resectable malignant biliary obstruction (MBO). However, modification of current FCSEMS designed originally for nonresectable MBO is needed to be a proper stent for PBD. The aim of this study was to evaluate the possible superiority of non-flared modified FCSEMS (M-FCSEMS) with 12-mm diameter and waist of central portion over PS in patients with resectable MBO. METHODS Eighty-five consecutive patients underwent PBD followed by operation from August 2015 to December 2017. In each M-FCSEMS and PS group, 29 patients were matched for age, sex, body mass index, and preoperative albumin and bilirubin levels. RESULTS The overall technical success rates of PBD using M-FCSEMS and PS were 100%. The time to operation was similar between groups (18.6 ± 10.8 vs 19.3 ± 11.6 days, respectively; P = 0.843). The prevalence of PBD-related adverse events (AEs) was 6.9% (2/29) in the M-FCSEMS group versus 27.6% (8/29) in the PS group (P = 0.037). Re-intervention before operation was required in 20.7% (6/29) of patients in the PS group but no patients in the M-FCSEMS group (P = 0.023). No differences were found between perioperative AEs in the M-FCSEMS and PS groups (27.5% vs 31.0%, respectively; P = 0.773). CONCLUSION Modified FCSEMS led to lower PBD-related AEs, re-intervention rate, and comparable perioperative AEs compared with PS. M-FCSEMS may be a potential novel stent for PBD in patients with resectable MBO.
