Abstract
Background and study aims Digital single-operator cholangioscopy (DSOC) allows the diagnosis of biliary duct disorders and treatment for complicated stones. However, these technologies have limitations such as the size of the probe and working channel, excessive cost, and low image resolution. Recently, a novel DSOC system (eyeMAX, Micro-Tech, Nanjing, China) was developed to address these limitations. We aimed to evaluate the usefulness and safety of a novel 9F and 11F DSOC system in terms of neoplastic diagnostic accuracy based on visual examination, ability to evaluate tumor extension and to achieve complete biliary stone clearance, and procedure-related adverse events (AEs). Patients and methods Data from ≥ 18-year-old patients who underwent DSOC from July 2021 to April 2022 were retrospectively recovered and divided into a diagnostic and a therapeutic cohort. Results A total of 80 patients were included. In the diagnostic cohort (n = 49/80), neovascularity was identified in 26 of 49 patients (46.9%). Biopsy was performed in 65.3% patients with adequate tissue sample obtained in 96.8% of cases. Biopsy confirmed neoplasia in 23 of 32 cases. DSOC visual impression achieved 91.6% sensitivity and 87.5% specificity in diagnosing neoplasms. In the therapeutic cohort (n = 43/80), 26 of 43 patients required lithotripsy alone. Total stone removal was achieved in 71% patients in the first session. Neither early nor late AEs were documented in either the diagnostic or therapeutic cohort. Conclusions The novel DSOC device has excellent diagnostic accuracy in distinguishing neoplastic biliary lesions as well as therapeutic benefits in the context of total stone removal, with no documented AEs.

Abstract
INTRODUCTION The study aimed to develop international consensus recommendations on the safe use of lumen-apposing metal stents (LAMSs) for on- and off-label indications. METHODS Based on the available literature, statements were formulated and grouped into the following categories: general safety measures, peripancreatic fluid collections, endoscopic ultrasound (EUS)-biliary drainage, EUS-gallbladder drainage, EUS-gastroenterostomy, and gastric access temporary for endoscopy. The evidence level of each statement was determined using the Grading of Recommendations Assessment, Development, and Evaluation methodology.International LAMS experts were invited to participate in a modified Delphi process. When no 80% consensus was reached, the statement was modified based on expert feedback. Statements were rejected if no consensus was reached after the third Delphi round. RESULTS Fifty-six (93.3%) of 60 formulated statements were accepted, of which 35 (58.3%) in the first round. Consensus was reached on the optimal learning path, preprocedural imaging, the need for airway protection and essential safety measures during the procedure, such as the use of Doppler, and measurement of the distance between the gastrointestinal lumen and the target structure. Specific consensus recommendations were generated for the different LAMS indications, covering, among others, careful patient selection, the preferred size of the LAMS, the need for antibiotics, the preferred anatomic location of the LAMS, the need for coaxial pigtail placement, and the appropriate management of LAMS-related adverse events. DISCUSSION Through a modified international Delphi process, we developed general and indication-specific experience- and evidence-based recommendations on the safe use of LAMS.

Abstract
1: ESGE recommends a prolonged course of a prophylactic broad-spectrum antibiotic in patients with ascites who are undergoing therapeutic endoscopic ultrasound (EUS) procedures.Strong recommendation, low quality evidence. 2: ESGE recommends placement of partially or fully covered self-expandable metal stents during EUS-guided hepaticogastrostomy for biliary drainage in malignant disease.Strong recommendation, moderate quality evidence. 3: ESGE recommends EUS-guided pancreatic duct (PD) drainage should only be performed in high volume expert centers, owing to the complexity of this technique and the high risk of adverse events.Strong recommendation, low quality evidence. 4: ESGE recommends a stepwise approach to EUS-guided PD drainage in patients with favorable anatomy, starting with rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), followed by antegrade or transmural drainage only when RV-ERP fails or is not feasible.Strong recommendation, low quality evidence. 5: ESGE suggests performing transduodenal EUS-guided gallbladder drainage with a lumen-apposing metal stent (LAMS), rather than using the transgastric route, as this may reduce the risk of stent dysfunction.Weak recommendation, low quality evidence. 6: ESGE recommends using saline instillation for small-bowel distension during EUS-guided gastroenterostomy.Strong recommendation, low quality evidence. 7: ESGE recommends the use of saline instillation with a 19G needle and an electrocautery-enhanced LAMS for EUS-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) procedures.Strong recommendation, low quality evidence. 8: ESGE recommends the use of either 15- or 20-mm LAMSs for EDGE, with a preference for 20-mm LAMSs when considering a same-session ERCP.Strong recommendation, low quality evidence.

Abstract
1: ESGE recommends the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) over percutaneous transhepatic biliary drainage (PTBD) after failed endoscopic retrograde cholangiopancreatography (ERCP) in malignant distal biliary obstruction when local expertise is available.Strong recommendation, moderate quality evidence. 2: ESGE suggests EUS-BD with hepaticogastrostomy only for malignant inoperable hilar biliary obstruction with a dilated left hepatic duct when inadequately drained by ERCP and/or PTBD in high volume expert centers.Weak recommendation, moderate quality evidence. 3: ESGE recommends that EUS-guided pancreatic duct (PD) drainage should only be considered in symptomatic patients with an obstructed PD when retrograde endoscopic intervention fails or is not possible.Strong recommendation, low quality evidence. 4: ESGE recommends rendezvous EUS techniques over transmural PD drainage in patients with favorable anatomy owing to its lower rate of adverse events.Strong recommendation, low quality evidence. 5: ESGE recommends that, in patients at high surgical risk, EUS-guided gallbladder drainage (GBD) should be favored over percutaneous gallbladder drainage where both techniques are available, owing to the lower rates of adverse events and need for re-interventions in EUS-GBD.Strong recommendation, high quality of evidence. 6: ESGE recommends EUS-guided gastroenterostomy (EUS-GE), in an expert setting, for malignant gastric outlet obstruction, as an alternative to enteral stenting or surgery.Strong recommendation, low quality evidence. 7: ESGE recommends that EUS-GE may be considered in the management of afferent loop syndrome, especially in the setting of malignancy or in poor surgical candidates. Strong recommendation, low quality evidence. 8: ESGE suggests that endoscopic ultrasound-directed transgastric ERCP (EDGE) can be offered, in expert centers, to patients with a Roux-en-Y gastric bypass following multidisciplinary decision-making, with the aim of overcoming the invasiveness of laparoscopy-assisted ERCP and the limitations of enteroscopy-assisted ERCP.Weak recommendation, low quality evidence.

Abstract
BACKGROUND : This study evaluated an oroenteric catheter (OEC)-assisted technique to distend the enteric loop for endoscopic ultrasound-guided gastroenterostomy (EUS-GE) in patients with gastric outlet obstruction (GOO). METHODS : Patient outcomes were reviewed. Proximal enteric loops were filled with water via an OEC (7 Fr or 8 Fr), providing a target for EUS-GE using a lumen-apposing metal stent (15-mm caliber). Clinical success was defined as toleration of a non-liquid diet by Day 3. RESULTS : 42 patients (mean age 73.1 [SEM 2.8] years; 23 male) underwent EUS-GE for malignant (n = 37) and benign (n = 5) duodenal strictures. EUS-GE creation was successful in 41/42 (98 %), with mean procedure time of 36 (SEM 3) minutes and no serious complications. Clinical success was achieved in 39/42 (93 %) at 5.7 (SEM 2.6) months' follow-up. Of 14 patients who died, 13 (93 %) maintained oral intake until death. EUS-GE provided good symptom relief in all 28 surviving patients until follow-up. CONCLUSIONS : OEC-assisted EUS-GE provided satisfactory relief of GOO symptoms, with high technical success (98 %) and no serious complications.

Abstract
BACKGROUND AND AIMS Since 2008, a plethora of research studies has compared the efficacy of water-assisted (aided) colonoscopy (WAC) and underwater resection (UWR) of colorectal lesions with standard colonoscopy. We reviewed and graded the research evidence with potential clinical application. We conducted a modified Delphi consensus among experienced colonoscopists on definitions and practice of water immersion (WI), water exchange (WE), and UWR. METHODS Major databases were searched to obtain research reports that could potentially shape clinical practice related to WAC and UWR. Pertinent references were graded (Grading of Recommendations, Assessment, Development and Evaluation). Extracted data supporting evidence-based statements were tabulated and provided to respondents. We received responses from 55 (85% surveyed) experienced colonoscopists (37 experts and 18 nonexperts in WAC) from 16 countries in 3 rounds. Voting was conducted anonymously in the second and third round, with ≥80% agreement defined as consensus. We aimed to obtain consensus in all statements. RESULTS In the first and the second modified Delphi rounds, 20 proposed statements were decreased to 14 and then 11 statements. After the third round, the combined responses from all respondents depicted the consensus in 11 statements (S): definitions of WI (S1) and WE (S2), procedural features (S3-S5), impact on bowel cleanliness (S6), adenoma detection (S7), pain score (S8), and UWR (S9-S11). CONCLUSIONS The most important consensus statements are that WI and WE are not the same in implementation and outcomes. Because studies that could potentially shape clinical practice of WAC and UWR were chosen for review, this modified Delphi consensus supports recommendations for the use of WAC in clinical practice.

Abstract
Background Recently, underwater endoscopic mucosal resection (UEMR) has shown promising results in the management of colorectal polyps. Some studies have shown better outcomes compared to conventional endoscopic mucosal resection (EMR). We conducted this systematic review and meta-analysis to compare UEMR and EMR in the management of colorectal polyps. Methods We searched several databases from inception to November 2019 to identify studies comparing UEMR and EMR. Outcomes assessed included rates of en bloc resection, complete macroscopic resection, recurrent/residual polyps on follow-up colonoscopy, complete resection confirmed by histology and adverse events. Pooled risk ratios (RR) with 95 % confidence interval were calculated using a fixed effect model. Heterogeneity was assessed by I 2 statistic. Funnel plots and Egger's test were used to assess publication bias. We used the Newcastle-Ottawa scale (NOS) for assessment of quality of observational studies, and the Cochrane tool for assessing risk of bias for RCTs Results Seven studies with 1291 patients were included; two were randomized controlled trials and five were observational. UEMR demonstrated statistically significantly better efficacy in rates of en bloc resection, pooled RR 1.16 (1.08, 1.26), complete macroscopic resection, pooled RR 1.28 (1.18, 1.39), recurrent/residual polyps; pooled RR 0.26 (0.12, 0.56) and complete resection confirmed by histology; pooled RR 0.75 (0.57, 0.98). There was no significant difference in adverse events (AEs); pooled RR 0.68 (0.44, 1.05). Conclusions This meta-analysis found statistically significantly better rates of en bloc resection, complete macroscopic resection, and lower risk of recurrent/residual polyps with UEMR compared to EMR. We found no significant difference in AEs between the two techniques.

Abstract
Background and aim As the post-peak phase of the epidemic is approaching, there is an urgent need of an action plan to help resume endoscopy activity. To manage the Covid-19 pandemic-imposed backlog of postponed colonoscopy examinations, an efficient approach is needed. The practice of on-demand sedation with benzodiazepines and/or opiates will allow most patients to complete a water-aided examination with minimal or no sedation. Other methods reported to minimize patient discomfort during colonoscopy can be used, in addition to water-aided techniques. Unsedated or minimally sedated patients who do not require recovery or require a shorter one allow rapid turnaround. The practice obviates the need for assistance with deep sedation from anesthesiologists, who may be in short supply. Trainee education in water-aided colonoscopy has been demonstrated to confer benefits. This review provides some insights into the impact of Covid-19 on endoscopy services, challenges ahead, and possible solutions to help recovery of colonoscopy work and training.

Abstract
BACKGROUND AND AIMS EUS-guided biliary drainage has emerged as a technique to enable endobiliary drainage in failed ERCP. A newer model, lumen-apposing metal stents (LAMS), with a cautery-enhanced delivery system became available in the USA in late 2015. This cautery-tipped version may facilitate EUS-guided choledochoduodenostomy (EUS-CD), but data using this model are lacking. METHODS We reviewed outcomes of attempted EUS-CD using cautery-enhanced LAMS from 6, US centers. The following data were collected: patient and procedure details, technical success, adverse events, clinical success (resolution of jaundice or improvement in bilirubin > 50%), and biliary re-interventions. RESULTS EUS-CD was attempted in 67 patients (mean age 68.8) with malignant obstruction after failed ERCP between September 2015 and April 2018. EUS-CD was technically successful in 64 (95.5%). A plastic or metal stent was inserted through the lumen of the deployed LAMS in 50 of 64 (78.1%) patients to maintain a non-perpendicular LAMS axis into the bile duct. Adverse events occurred in 4 (6.3%) and included: abdominal pain (n = 2), peritonitis that responded to antibiotics (n = 1), and bleeding requiring transfusion (n = 1). Among 40 patients with follow-up of > 4 weeks, clinical success was achieved in 100%. Biliary re-interventions for obstruction were needed in 7(17.5%), in 3 of 6 (50.0%) that underwent EUS-CD with LAMS alone versus 4 of 34 (5%) with LAMS plus an axis-orienting stent (p = 0.02). CONCLUSION EUS-CD using LAMS with cautery-enhanced delivery systems has high technical and clinical success rates, with a low rate of adverse events. Inserting an axis-orienting stent through the lumen of the LAMS may reduce the need for biliary re-interventions.

Abstract
Gastrointestinal bleeding as a sequela of portal hypertension can be catastrophic and fatal. Endoscopic and endosonographic therapy play a critical role in management of such bleeding- both for hemostasis of active bleeding and bleeding prophylaxis. Variceal band ligation is established as the standard intervention for esophageal varices. For other sources of portal hypertension-related bleeding, or for salvage therapy for esophageal varices, a variety of endoscopic techniques are available. Endoscopic ultrasound may be used to enhance endoscopic management, particularly for gastric and ectopic varices.

Abstract
Background and Objectives EUS-guided drainage, and direct endoscopic necrosectomy (DEN) of walled-off necrosis (WON) using a lumen-apposing metal stent (LAMS) is safe and effective. Early debridement of WON may improve overall clinical outcomes. The aim of this study is to perform a multicenter retrospective study to compare the clinical outcomes and predictors of success for endoscopic drainage of WON with LAMS followed by immediate or delayed DEN performed at standard intervals. Methods Patients with WON managed by EUS-guided drainage with LAMS were divided into 2 groups: (1) those that underwent immediate DEN at the time of stent placement and (2) those that underwent delayed DEN 1 week after stent placement. DEN was subsequently performed every 1-2 week (s). Technical success (successful placement of LAMS), adverse events (AEs), and clinical success (complete resolution of the WON) were evaluated. Results Totally, 271 patients underwent WON drainage with LAMS: 69 who underwent immediate DEN and 202 who underwent delayed DEN. The technical success for LAMS placement was 100% in both groups. There was no significant difference in the overall procedural AEs between the immediate and delayed DEN groups (P = 7.2% vs. 9.4%; P = 0.81). Stent dislodgement during index endoscopy occurred in three patients in the immediate DEN group compared to zero in the delayed DEN group (P = 0.016); all three dislodgements occurred during necrosectomy. Clinical success for WON resolution in the immediate DEN group was 91.3% compared to 86.1% in the delayed DEN group (P = 0.3). The mean number of necrosectomy sessions for WON resolution was significantly lower in the immediate DEN group compared to the delayed DEN group (3.1 vs. 3.9, P < 0.001). Performing DEN at the time of stent placement was an independent predictor for resolution of WON with lesser number of DEN sessions (odds ratio 2.3; P = 0.004). Conclusions DEN at the time of initial stent placement reduces the number of necrosectomy sessions required for successful clinical resolution of WON.

Abstract
The lumen-apposing metal stent is the first stent specifically designed for endoscopic ultrasound-guided transluminal drainage of extraintestinal fluid collections. With the "hot" electrocautery-enhanced delivery system, this platform marks the most recent evolutionary stage of endoscopic therapy of pancreatic fluid collections. The lumen-apposing metal stent platform has made endoscopic drainage of pancreatic fluid collections easier and safer, while serving as a port for safe entry into the cyst cavity to extend the reach of endoscopic diagnosis and therapy. Tools conceived for endoscopic ultrasound-guided transluminal intervention have emerged and are opening the door to new frontiers of endoscopic transluminal therapy.

Abstract
Background and aims Precut papillotomy is widely used after failed biliary cannulation. Endoscopic ultrasound (EUS)-guided biliary access techniques are newer methods to facilitate access and therapy in failed cannulation. We evaluated the impact of EUS-guided biliary access on endoscopic retrograde cholangiopancreatography (ERCP) success and compared these techniques to precut papillotomy. Patients and methods We retrospectively compared two ERCP cohorts. One cohort consisted of biliary ERCPs (n = 1053) attempted in patients with native papillae and surgically unaltered anatomy in whom precut papillotomy and/or EUS-guided biliary access were routinely performed immediately after failed cannulation. This cohort was compared with a similar ERCP cohort (n = 1062) in which only precut papillotomy was available for failed cannulation. The following outcomes were compared: conventional cannulation success, rates of attempted advanced access techniques (precut or EUS), precut success, EUS-guided biliary access success, and ERCP failure rates. Results Although conventional cannulation success, rates of attempted advanced access technique (precut or EUS), and precut success were similar, the ERCP failure rate was lower when both EUS-guided biliary access and precut were available (1.0 % [95 % confidence interval (CI) 0.4 - 1.6]), compared with when only precut was possible for failed access (3.6 % [95 %CI 2.5 - 4.7]; P < 0.001). Success for EUS-guided biliary access (95.1 % [95 %CI 89.7 - 100]) was significantly higher than for precut (75.3 % [95 %CI 68.2 - 82.4]; P < 0.001), and mainly due to superiority in malignant obstruction (93.5 % vs. 64 %; P < 0.001). Conclusions EUS-guided biliary access decreases the rate of therapeutic biliary ERCP failure. Our results support the use of EUS-guided biliary access to optimize single-session ERCP success. In experienced hands, these techniques appear as effective, if not more so, than precut papillotomy.

Abstract
BACKGROUND AND AIMS ERCP inherently involves radiation exposure. Nonradiation ERCP has been described in pregnancy. Theoretically, the same techniques could be applied to the general population. We prospectively assessed the feasibility of nonradiation, EUS-based ERCP in nonpregnant patients with choledocholithiasis. METHODS Consecutive patients referred for ERCP for choledocholithiasis were recruited over a 1-year period. Patients providing study consent underwent the following procedural protocol. First, EUS was performed to verify the presence, size, and number of stones. Second, biliary cannulation was attempted without fluoroscopy for a maximum of 10 minutes. Selective cannulation was based on deep insertion with visible bile in the catheter on aspiration. Third, for stone removal, sphincterotomy was performed and stones were removed using a basket or balloon. The number of stones exiting the papilla was matched to the number seen on EUS. Finally, once the duct was deemed clear by the endoscopist, a final occlusion cholangiogram and ductal sweep served as the reference standard for confirmation of stone clearance. RESULTS Nonradiation ERCP was attempted in 31 patients. Cannulation without fluoroscopy was successful in 26 patients (84%). Complete stone removal without fluoroscopy was achieved in all 26 of these cases. The 5 patients with failed nonfluoroscopic cannulation required double guidewire (n = 2) or precut papillotomy (n = 3) for deep biliary access and subsequent stone clearance. One patient who required precut papillotomy for access developed moderate post-ERCP pancreatitis (3%). CONCLUSIONS Nonradiation, EUS-based ERCP for uncomplicated choledocholithiasis appears to be successful and safe. (Clinical trial registration number: NCT01678391.).

Abstract
BACKGROUND AND AIMS EMR of adenomas involving the appendiceal orifice (AO) is controversial because of a high risk of perforation and incomplete resection. We evaluated the feasibility, safety, and outcomes of underwater EMR (UEMR) without submucosal injection for the treatment of adenomas involving the AO. METHODS This was a prospective, observational study of a standardized UEMR technique without submucosal injection for adenomas involving the AO in 27 consecutive patients meeting inclusion and exclusion criteria. Surveillance colonoscopy included biopsy sampling of the EMR site and base of the AO. Main outcome measurements include technical success, histology, resection time, adverse events, and follow-up data. RESULTS Over 42 months, UEMR of adenomas involving the AO (rim, 5 patients; inside, 22 patients) was attempted in 27 consecutive patients. Median adenoma size was 15 mm (range, 8 to 50). UEMR was successful in 24 patients (89%). Four patients were referred to surgery, 3 with UEMR failure because of an inability to exclude the adenoma extending into the appendix at the index procedure and 1 with invasive adenocarcinoma in the UEMR specimen. The median resection time was 3 minutes (range, 1 to 75). Adverse events consisted of postpolypectomy syndrome in 2 patients (7%). There was no perforation, bleeding requiring transfusion, or appendicitis. Final histology was tubular adenoma (7), tubulovillous adenoma (4), sessile serrated adenoma (15), and invasive adenocarcinoma (1). Twenty-one of 23 patients (91%), not referred to surgery, had follow-up colonoscopy with biopsy sampling of the resection site after a median of 29 weeks (range, 12 to 139) after resection. Residual adenoma was found in 2 of 21 patients (10%). CONCLUSION On an intention-to-treat basis, UEMR without submucosal injection enabled safe and complete endoscopic resection of AO lesions. Close surveillance for residual or recurrence is warranted. ( CLINICAL TRIALS REGISTRATION NUMBER NCT01750619.).

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the primary approach to drain an obstructed pancreatic or biliary duct. Failed biliary drainage is traditionally referred for percutaneous transhepatic biliary drainage or surgical bypass, which carry significantly higher morbidity and mortality rates compared with ERCP and transpapillary drainage. Endoscopic ultrasound provides a real-time imaging platform to access and deliver therapy to organs and tissues outside of the bowel lumen. The bile and pancreatic ducts can be directly accessed from the stomach and duodenum, offering an alternative to ERCP when this fails or is not feasible.

Abstract
Expert knowledge of endoscopic management of gastric varices is essential, as these occur in 20% of patients with portal hypertension. Bleeding is relatively uncommon, but carries significant mortality when this occurs. Inability to directly target intravascular injections and the potential complication related to glue embolization has resulted in the development of novel techniques. Direct visualization of the varix lumen using endoscopic ultrasound (EUS) allows targeted therapy of feeder vessels with real-time imaging. EUS-guided combination therapy with endovascular coiling and cyanoacrylate injections promise to provide reduced complication rates, increased obliteration of varices, and reduced long-term rebleeding rates.

Abstract
The gastrointestinal tract provides a unique "window" to access vascular structures in the mediastinum and abdomen. The advent of interventional endoscopic ultrasound (EUS) has enabled access to these structures with a standard fine-needle aspiration (FNA) needle. Sclerosants, cyanoacrylate, and coils can be delivered through the lumen of the FNA needle. EUS-guided treatment of gastric varices has theoretical advantages over conventional endoscopy-guided treatment. Controlled studies are needed to determine the role of EUS-guided treatment for primary and secondary prevention of variceal bleeding. There is a growing list of novel indications for EUS-guided vascular therapy that include portal vein angiography and pressure measurements, intrahepatic portosystemic shunt placement, and micro coil embolization of vascular structures. Additionally, access and therapy of the heart and surrounding structures appears feasible.

Abstract
BACKGROUND Both EUS and ERCP sampling techniques may provide tissue diagnoses in suspected malignant biliary obstruction. However, there are scant data comparing these 2 methods. OBJECTIVE To compare EUS-guided FNA (EUS-FNA) and ERCP tissue sampling for the diagnosis of malignant biliary obstruction. DESIGN Prospective, comparative, single-blind study. SETTING Tertiary center. PATIENTS Fifty-one patients undergoing same-session EUS and ERCP for the evaluation of malignant biliary obstruction over a 1-year period. INTERVENTIONS EUS-FNA and ERCP tissue sampling with biliary brush cytology and intraductal forceps biopsies. MAIN OUTCOME MEASUREMENTS Diagnostic sensitivity and accuracy of each sampling method compared with final diagnoses. RESULTS EUS-FNA was more sensitive and accurate than ERCP tissue sampling (P < .0001) in 51 patients with pancreatic cancers (n = 34), bile duct cancers (n = 14), and benign biliary strictures (n = 3). The overall sensitivity and accuracy were 94% and 94% for EUS-FNA, and 50% and 53% for ERCP sampling, respectively. EUS-FNA was superior to ERCP tissue sampling for pancreatic masses (sensitivity, 100% vs 38%; P < .0001) and seemed comparable for biliary masses (79% sensitivity for both) and indeterminate strictures (sensitivity, 80% vs 67%). LIMITATIONS Single-center study. CONCLUSION EUS-FNA is superior to ERCP tissue sampling in evaluating suspected malignant biliary obstruction, particularly for pancreatic masses. EUS-FNA appears similar to ERCP sampling for biliary tumors and indeterminate strictures. Given the superior performance characteristics of EUS-FNA and the higher incidence of pancreatic cancer compared with cholangiocarcinoma, EUS-FNA should be performed before ERCP in all patients with suspected malignant biliary obstruction.

Abstract
OBJECTIVE Transluminal pseudocyst drainage with currently available tools remains technically challenging, time consuming and limited to fluid collections adherent to the GI tract. Multiple tools and steps are still required to achieve pseudocyst drainage. We evaluated a novel kit to facilitate endoscopic ultrasonography (EUS)-guided access, drainage and rapid decompression in a porcine model. METHODS The kit consists of the NAVIX access device and the AXIOS stent delivery system. The NAVIX contains an inner trocar for puncture and an outer dual balloon catheter for anchorage and dilation. The AXIOS stent is a fully covered dual flanged stent. Both are inserted through the working channel of a curved linear array echoendoscope. In a porcine model, a gallbladder was used as a proxy for a pseudocyst. RESULTS Six Yorkshire pigs underwent this procedure successfully without complication and 3 of them were kept alive. After a 4-week implantation period, the AXIOS stents were removed easily using a snare and the 3 animals were observed for an additional 4 weeks. The stents were well-tolerated by the stomach and gallbladder tissues, as confirmed by weekly endoscopic inspection, gross necropsy and histopathology. CONCLUSION EUS-guided transluminal access and drainage of the porcine gallbladder was technical feasible using a novel kit. This kit has the potential to simplify, streamline, and improve the safety of pancreatic pseudocyst drainage.

Abstract
BACKGROUND EMR for the treatment of duodenal adenomas is challenging due to a thin wall and rich vascularity. OBJECTIVE To evaluate a novel technique of "underwater" EMR without prior submucosal injection for the removal of large (≥2 cm) laterally spreading nonampullary duodenal adenomas. DESIGN Prospective, observational study. SETTING Tertiary academic referral center. PATIENTS Twelve patients (median age, 60 years) meeting the inclusion criteria. INTERVENTIONS Piecemeal EMR technique after sterile water submersion when using a double-channel endoscope. MAIN OUTCOME MEASUREMENTS Technical success, adverse events, completeness of resection on follow-up endoscopy. RESULTS Median adenoma size was 35 mm (25% greater than one-half circumference, 50% equal to one-third to one-half circumference, and 25% less than one-third circumference). Median procedure time was 65 minutes (range, 32-151). Final histology was tubular adenoma (7), tubulovillous adenoma (1), villous adenoma (3), and high-grade dysplasia (1). Eleven patients (92%) met the primary endpoint (technical success) and all patients met the secondary endpoint (completeness of resection). Median interval until follow-up endoscopy was 16 weeks (range, 11-56). Adverse events were as follows: delayed bleeding (3 patients, of whom 2 required transfusions), water intoxication syndrome manifested by altered mental status and hyponatremia (1), and stricture formation (1) that responded to balloon dilation. No perforation or postresection abdominal pain was found. LIMITATIONS Single operator, single center, small sample size, limited follow-up. CONCLUSION Underwater EMR for large sessile duodenal adenomas has high success rates for complete removal. The risk of delayed bleeding is significant, and precautions are needed when infusing a large volume of fluid into the GI tract.

Abstract
Barrett's esophagus with dysplasia is commonly treated with radiofrequency ablation (RFA). Despite its effectiveness, a concern of any ablative technique is the development of subsquamous intestinal metaplasia, which could have potential for future neoplastic progression. To date, 34 cases of subsquamous neoplasia have been described in the literature after various ablation therapies. However, only three cases of subsquamous neoplasia have been reported after successful RFA treatment of dysplastic Barrett's esophagus. In this case series, we report on four additional cases of subsquamous neoplasia detected after successful endoscopic resection and RFA for neoplastic and dysplastic Barrett's esophagus. All four patients were treated successfully with endoscopic resection of their recurrent subsquamous neoplastic and dysplastic lesions. This case series highlights the need for continued surveillance following successful treatment of dysplastic Barrett's esophagus with RFA.

Abstract
PURPOSE Same session endosonography (EUS) immediately prior to scheduled endoscopic retrograde cholangiopancreatography (ERCP) may eliminate the need for ERCP and its associated risks in pregnant patients with no evidence of choledocholithiasis on EUS. In patients with choledocholithiasis, EUS provides information regarding the location, size and number of stones present, which helps guide biliary interventions and confirm stone clearance without the use of fluoroscopy. METHODS We retrospectively identified 10 pregnant patients referred to our tertiary endoscopy center for suspected choledocholithiasis between June 2008 and January 2012. All patients underwent same-session EUS-based ERCP. RESULTS Of 10 pregnant patients managed with EUS-guided ERCP, six were found to have common bile duct stones and went on to ERCP. Four patients with no evidence of choledocholithiasis on EUS did not undergo ERCP. Patients with confirmed choledocholithiasis underwent ERCP without the use of fluoroscopy using the additional information provided by EUS. CONCLUSIONS Same-session EUS immediately prior to scheduled ERCP may eliminate the need for ERCP and its risks in pregnant patients with no evidence of choledocholithiasis on EUS. In patients with confirmed choledocholithiasis, EUS provided additional information regarding the location, number and size of bile duct stones, which enabled the successful clearance of the bile duct without the use of fluoroscopy.

Abstract
BACKGROUND We report a novel technique of retract-ligate-unroof-biopsy (RLUB) for the diagnosis and treatment of large nonpedunculated upper GI stromal tumors originating from the muscularis propria. OBJECTIVE Proof-of-concept evaluation of the RLUB technique. DESIGN Pilot and feasibility study. SETTING Tertiary care center. PATIENTS Sixteen patients (median age 71 years) fulfilling the following inclusion criteria: poor surgical candidates with lesions that are broad based with a benign appearance, originating from the muscularis propria, size 2 cm or larger. INTERVENTIONS A double-channel endoscope was used to simultaneously retract the stromal tumor while advancing an endoloop beyond the tumor for ligation. The overlying tissue was incised ("unroofed") to expose and partially enucleate the tumor, and multiple biopsy samples were obtained. After unroofing, an additional endoloop was placed below the previous one by using the loop-over-loop technique to reinforce enucleation and ischemic ablation. MAIN OUTCOME MEASUREMENTS Successful ligation, immunohistochemistry and mitotic index yield, therapeutic ablation, adverse events. RESULTS Technical success was achieved in 13 of 16 patients (81%). Immunohistology of biopsy specimens: GI stromal tumor (n = 10), leiomyoma (n = 3). Twelve of 13 patients (92%) with follow-up (median 22 weeks, range 1-82.5 weeks) had confirmed tumor ablation by endoscopy and EUS. One patient with partial resolution was re-treated, but was subsequently lost to follow-up. Delayed bleeding occurred in 2 patients that required hospitalization and blood transfusions, both successfully controlled with repeat endolooping. One patient reported transient pain. LIMITATIONS Single center, single operator, small sample size. CONCLUSIONS The RLUB technique is feasible as a platform for full-thickness treatment of stromal tumors. Limitations encountered included technical challenges and delayed bleeding. Further developmental work is needed.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) has become the preferred procedure for biliary or pancreatic drainage in various pancreatico-biliary disorders. With a success rate of more than 90%, ERCP may not achieve biliary or pancreatic drainage in cases with altered anatomy or with tumors obstructing access to the duodenum. In the past those failures were typically managed exclusively by percutaneous approaches by interventional radiologists or surgical intervention. The morbidity associated was significant especially in those patients with advanced malignancy, seeking minimally invasive interventions and improved quality of life. With the advent of biliary drainage via endoscopic ultrasound (EUS) guidance, EUS guided biliary drainage has been used more frequently within the last decade in different countries. As with any novel advanced endoscopic procedure that encompasses various approaches, advanced endoscopists all over the world have innovated and adopted diverse EUS guided biliary and pancreatic drainage techniques. This diversity has resulted in variations and improvements in EUS Guided biliary and pancreatic drainage; and over the years has led to an extensive nomenclature. The diversity of techniques, nomenclature and recent progress in our intrumentation has led to a dedicated meeting on May 7th, 2011 during Digestive Disease Week 2011. More than 40 advanced endoscopists from United States, Brazil, Mexico, Venezuela, Colombia, Italy, France, Austria, Germany, Spain, Japan, China, South Korea and India attended this pivotal meeting. The meeting covered improved EUS guided biliary access and drainage procedures, terminology, nomenclature, training and credentialing; as well as emerging devices for EUS guided biliary drainage. This paper summarizes the meeting’s agenda and the conclusions generated by the creation of this consortium group.

Abstract
BACKGROUND Endosonography (EUS)-guided transmural pseudocyst drainage is a multistep procedure currently performed with different "off-the-shelf" accessories developed for other applications. Multiple device exchanges over-the-wire is time consuming and risks loss of wire access. This report describes the technical feasibility and outcomes for EUS-guided drainage of pancreatic fluid collections using a novel exchange-free device developed for translumenal therapy. METHODS Between April and November 2010, 14 patients (9 men; mean age, 49.9 years) with pancreatic fluid collection (mean size, 102 mm) underwent 16 EUS-guided drainage procedures using the exchange-free access device at a single tertiary care center. The trocar of the exchange-free device was used to gain pseudocyst access. The dual-balloon catheter then was advanced over the trocar, followed by inflation of the (first) anchor balloon. Cyst contents were sampled, and contrast was injected to define the pseudocyst anatomy. The first guidewire was inserted into the cyst cavity. The cystenterostomy tract was dilated to 10 mm with the (second) dilation balloon, followed by a second guidewire insertion. The exchange-free access device was removed, leaving the two guidewires in place for two double-pigtail stents. RESULTS The procedure was technically successful for all the patients. No acute procedure-related complications occurred. Late complications included a symptomatic leak in a patient who underwent drainage of a pancreatic uncinate pseudocyst from the second duodenum, a self-limited transfusion-dependent bleed after transbulbar drainage, and symptomatic pseudocyst infection. CONCLUSION Pseudocyst access, cystenterostomy tract dilation, and placement of two guidewires for dual stent drainage are technically feasible using an exchange-free access device. The device has the potential to standardize, simplify, and streamline EUS-guided pseudocyst drainage with a single instrument. Comparative studies with alternative tools and methods for pseudocyst drainage are warranted.
