Abstract
BACKGROUND AND AIMS Endoscopic ultrasound (EUS)-guided transmural drainage using a covered biflanged metal stent (CBFMS) and a conventional tubular biliary covered self-expandable metal stent (CSEMS) has recently been performed by EUS experts. However, appropriate traction force of the sheath to prevent the migration during stent deployment is well unknown. Herein, we assessed the anchoring force (AF) of the distal flange in CBFMSs and CSEMSs. METHODS The AFs of four CBFMSs (Stents AX, NG, PL, and SX) and six CSEMSs (Stents BF, BP, EG, HN, SP, and WF) were compared in an ex vivo setting. We assessed the AF produced by each stent using an EUS-guided transmural drainage model and an EUS-guided hepaticogastrostomy model consisting of sheet-shaped specimens of the stomach, gelatin gel, and gelatin tubes. RESULTS For CBFMSs, the maximum AF of Stent AX was significantly higher than those of Stents PL and SX (P < 0.05) in the porcine model. In the gelatin series, all stents except Stent NG showed a nearly similar AF. For CSEMSs, Stents HN, EG, BF, and WF showed gradual AF elevation in the porcine stomach. Stents SP and BP showed a lower AF than the other four stents. For the gelatin setting, the maximum AF of Stents HN, EG, and WF was higher than those of the other stents regardless of the type of specimens. CONCLUSIONS The significance of the AF and traction distance according to the property of various CBFMSs and CSEMSs could be elucidated using ex vivo models.

Abstract
Background and Objectives: Currently, pancreatic cystic lesions (PCLs) are recognized with increasing frequency and have become a more common finding in clinical practice. EUS is challenging in the diagnosis of PCLs and evidence-based decisions are lacking in its application. This study aimed to develop strong recommendations for the use of EUS in the diagnosis of PCLs, based on the experience of experts in the field. Methods: A survey regarding the practice of EUS in the evaluation of PCLs was drafted by the committee member of the International Society of EUS Task Force (ISEUS-TF). It was disseminated to experts of EUS who were also members of the ISEUS-TF. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized. Results: Fifteen questions were extracted and disseminated among 60 experts for the survey. Fifty-three experts completed the survey within the specified time frame. The average volume of EUS cases at the experts' institutions is 988.5 cases per year. Conclusion: Despite the limitations of EUS alone in the morphologic diagnosis of PCLs, the results of the survey indicate that EUS-guided fine-needle aspiration is widely expected to become a more valuable method.

Abstract
Background and Objectives: Recently, a 22G Franseen needle for EUS-guided fine-needle biopsy (EUS-FNB) with three novel symmetric heels has been developed to adequately obtain a core tissue. Methods: All 38 consecutive patients with pancreatic masses who underwent EUS-FNB using a Franseen needle were investigated retrospectively to assess the efficacy and safety of EUS-FNB using the Franseen needle. Then, the EUS-FNB outcomes and histological assessments of the tissue obtained by EUS-FNB using the Franseen needle and EUS-FNA using the conventional end-cut type needle for each of the 30 pancreatic ductal adenocarcinoma cases were compared. Results: An accurate histological diagnosis of the Franseen needle was achieved with a mean of 2 passes in 97.4% of patients. Although the accurate histological diagnosis rate of pancreatic ductal adenocarcinoma was not significantly different (96.7% vs. 93.3%, P = 0.55), the mean number of passes in the Franseen needle was significantly less than that in the conventional needle (2.1 ± 0.4 vs. 3.2 ± 0.8, P < 0.001). The presence of desmoplastic fibrosis with neoplastic cellular elements and venous invasion were significantly higher (96.7% vs. 40.0%, P < 0.001 and 23.3% vs. 0%, P < 0.01, respectively) and the amount of obtained tissue was significantly larger with the Franseen needle (2.13 mm2vs. 0.45 mm2, P < 0.001). Conclusions: EUS-FNB using the Franseen needle enables the acquisition of a larger amount of tissue sample and achieves an accurate histological diagnosis with a smaller number of passes than the conventional end-cut type needle.

Abstract
Objective Autoimmune pancreatitis (AIP) has been recognized as a benign disease, which that shows a prompt response to corticosteroid treatment (CST). It was previously believed to not be associated with cyst formation; however, a few cases of AIP-associated pancreatic cyst (PC) have been reported. Some cases were reported to have been effectively treated by CST, while others were refractory to CST. Many of the patients received interventional treatment. Until now, there has been no consensus on the therapeutic strategies for AIP-associated PC. The aim of the present study is to describe a therapeutic strategy for this condition. Methods We conducted a retrospective study of 5 cases of AIP-associated PC that were treated by endoscopic ultrasonography-guided pancreatic fluid collection drainage (ESPD) or CST at Tokyo Medical University Hospital between March 2012 and October 2016, analyzed the therapeutic outcomes, and performed a literature review. Results The initial treatments included CST (n=2) and ESPD (n=3). All of the PCs disappeared after treatment In 1 of the patients who received CST case and 3 of the patients who received ESPD; however, the PC did not disappear in one of the patients who received CST (corticosteroid maintenance therapy), even after the dose of corticosteroids was increased; ESPD was eventually performed and the PC disappeared. There were no procedure-related complaints. Conclusion We propose that CST be administered as the first-line treatment for AIP-associated PC, particularly in cases of PC without a history of CST. However, ESPD can be applied to treat cases of corticosteroid refractory PC.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasonography-guided pancreatic duct drainage (EUS-PD) has been reported as an alternative for failed conventional endoscopic retrograde cholangiopancreatography (ERCP). However, there are few dedicated devices for EUS-PD. Recently, we have developed a new plastic stent dedicated to EUS-PD and have conducted a feasibility study to evaluate its efficacy. In the current study, we evaluated the long-term efficacy of this new plastic stent. PATIENTS AND METHODS Thirty patients (61 ± 14.3 years old, 14 men) with acute recurrent pancreatitis caused by a stricture in the main pancreatic duct (MPD) or stenotic pancreatoenterostomy were treated at our institution using our recently developed 7Fr plastic stent between August 2013 and April 2017. RESULTS The stent was placed successfully in all patients (30/30) and early clinical success was achieved in all of them. Early adverse events (AEs) occurred in seven patients (23.3 %), namely, self-limited abdominal pain (n = 5), mild pancreatitis (n = 1), and bleeding which required transcatheter arterial embolization (n = 1). Two patients died of primary disease and three were lost to follow-up. The remaining 25 patients were followed up after initial EUS-PD for a median of 23 months (range, 6 - 44 months). Twenty patients required regular stent exchange (3 times; range, 1 - 12 times). Spontaneous stent dislodgement was observed in six patients. Four patients wanted their stents removed 1 year after the initial intervention. Twelve patients (48 %) had regular stent exchange 1 year after the initial intervention. Three patients converted to standard transpapillary pancreatic duct stenting by conventional ERCP. Finally, nine patients (36 %) had complete stent removal either intentionally or by spontaneous dislodgement without any symptoms. CONCLUSION The new plastic stent for EUS-PD was associated with not only short-term technical success but also long-term clinical success in the majority of patients evaluated in this study.

Abstract
BACKGROUND AND AIM Several experts of direct peroral videocholangioscopy (D-PVCS) using a conventional ultraslim endoscope have reported its usefulness for the diagnosis and therapy of biliary tract diseases. We have additionally developed a dedicated double-bending D-PVCS technique for freehand scope insertion. In this study, we developed an ex vivo training model for the freehand double-bending D-PVCS technique and compared it with the technique using a conventional ultraslim endoscope. METHODS The ex vivo model was made for training using a U-shape insertion pattern. A third prototype endoscope and an ultraslim upper gastrointestinal endoscope were used. Two experts and nine non-experts performed D-PVCS using the freehand technique. RESULTS The two experts could not advance the tip of the endoscope to the hilar portion using the freehand technique, but they could achieve technical successful insertion to the hilar portion with the third prototype cholangioscope using the freehand technique alone. The non-experts could not advance the tip of the endoscope to the bile duct using the freehand technique. On the other hand, two (22.2%) non-experts could advance the tip of the third prototype cholangioscope using the freehand technique before the training conducted by the experts. After the training, all the non-experts could advance the tip of the third prototype cholangioscope to the hilar portion. CONCLUSIONS The novel ex vivo model using a third prototype cholangioscope was useful for training in the use of the freehand D-PVCS technique.

Abstract
Antimicrobial therapy is a mainstay of the management for patients with acute cholangitis and/or cholecystitis. The Tokyo Guidelines 2018 (TG18) provides recommendations for the appropriate use of antimicrobials for community-acquired and healthcare-associated infections. The listed agents are for empirical therapy provided before the infecting isolates are identified. Antimicrobial agents are listed by class-definitions and TG18 severity grade I, II, and III subcategorized by clinical settings. In the era of emerging and increasing antimicrobial resistance, monitoring and updating local antibiograms is underscored. Prudent antimicrobial usage and early de-escalation or termination of antimicrobial therapy are now important parts of decision-making. What is new in TG18 is that the duration of antimicrobial therapy for both acute cholangitis and cholecystitis is systematically reviewed. Prophylactic antimicrobial usage for elective endoscopic retrograde cholangiopancreatography is no longer recommended and the section was deleted in TG18. Free full articles and mobile app of TG18 are available at: http://www.jshbps.jp/modules/en/index.php?content_id=47. Related clinical questions and references are also included.

Abstract
Although the diagnostic and severity grading criteria on the 2013 Tokyo Guidelines (TG13) are used worldwide as the primary standard for management of acute cholangitis (AC), they need to be validated through implementation and assessment in actual clinical practice. Here, we conduct a systematic review of the literature to validate the TG13 diagnostic and severity grading criteria for AC and propose TG18 criteria. While there is little evidence evaluating the TG13 criteria, they were validated through a large-scale case series study in Japan and Taiwan. Analyzing big data from this study confirmed that the diagnostic rate of AC based on the TG13 diagnostic criteria was higher than that based on the TG07 criteria, and that 30-day mortality in patients with a higher severity based on the TG13 severity grading criteria was significantly higher. Furthermore, a comparison of patients treated with early or urgent biliary drainage versus patients not treated this way showed no difference in 30-day mortality among patients with Grade I or Grade III AC, but significantly lower 30-day mortality in patients with Grade II AC who were treated with early or urgent biliary drainage. This suggests that the TG13 severity grading criteria can be used to identify Grade II patients whose prognoses may be improved through biliary drainage. The TG13 severity grading criteria may therefore be useful as an indicator for biliary drainage as well as a predictive factor when assessing the patient's prognosis. The TG13 diagnostic and severity grading criteria for AC can provide results quickly, are minimally invasive for the patients, and are inexpensive. We recommend that the TG13 criteria be adopted in the TG18 guidelines and used as standard practice in the clinical setting.

Abstract
Background and Objectives: Acquisition of core tissue on endoscopic ultrasound (EUS)-guided fine-needle aspiration has been regarded as important for establishing an accurate histological diagnosis. Recently, a new 20-gauge histology needle with reverse bevel (ProCore needle) and a 22-gauge needle with 3 novel symmetric heels (Acquire needle) have been developed. The aims of this animal experimental study were to assess the core tissue acquisition (TA) abilities of these new histology needles by comparing them with those of conventional 22-gauge needles and to evaluate the efficacy of suction for these needles. Materials and Methods: Three experienced echoendoscopists performed EUS-guided TA with and without suction using 43 types of needles. The amount of obtained tissue specimens and blood contamination was assessed using a scoring system, and the weight of the obtained tissue specimens was measured using an electronic balance. Results: The mean amount of core tissue score of the Acquire 22-gauge needle or ProCore 20-gauge needle was significantly higher than that of the conventional 22-gauge needles (Acquire 22-gauge needle vs. conventional 22-gauge needles: P = 0.024; ProCore 20-gauge needle vs. conventional 22-gauge needles: P = 0.001). There was no significant difference in the mean amount of core tissue score between the Acquire 22-gauge needle and the ProCore 20-gauge needle (P = 0.296). In the Acquire 22-gauge needle and ProCore 20-gauge needle, there was no significant difference between the mean amount of core tissue score with suction and that without suction (3.7 ± 0.4 vs. 3.5 ± 0.4, P = 0.734) although blood contamination increased (2.3 ± 0.7 vs. 1.6 ± 0.3, P = 0.061). Conclusion: The TA abilities of the ProCore 20-gauge needle and Acquire 22-gauge needle were better than those of the conventional 22-gauge needles. The efficacy of suction for the ProCore 20-gauge needle and Acquire 22-gauge needle was limited.

Abstract
Background and Objectives: EUS-guided biliary drainage (EUS-BD) was shown to be useful for malignant biliary obstruction (MBO). However, there is lack of consensus on how EUS-BD should be performed. Methods: This was a worldwide multi-institutional survey among members of the International Society of EUS conducted in February 2018. The survey consisted of 10 questions related to the practice of EUS-BD. Results: Forty-six endoscopists of them completed the survey. The majority of endoscopists felt that EUS-BD could replace percutaneous transhepatic biliary drainage after failure of ERCP. Among all EUS-BD methods, the rendezvous stenting technique should be the First choice. Self-expandable metal stents (SEMSs) were recommended by most endoscopists. For EUS-guided hepaticogastrostomy (HGS), superiority of partially-covered SEMS over fully-covered SEMS was not in agreement. 6-Fr cystotomes were recommended for fistula creation. During the HGS approach, longer SEMS (8 or 10 cm) was recommended. During the choledochoduodenostomy approach, 6-cm SEMS was recommended. During the intrahepatic (IH) approach, the IH segment 3 was recommended. Conclusion: This is the first worldwide survey on the practice of EUS-BD for MBO. There were wide variations in practice, and randomized studies are urgently needed to establish the best approach for the management of this condition.

Abstract
Background and Objectives Successful tract dilation is one of the most important steps to accomplish EUS-guided drainage. Although mechanical dilation is safer than electrocautery dilation, no dedicated mechanical dilator (MD) is currently available. Thus, we developed a new ultra-tapered MD for EUS-guided drainage. This study aimed to evaluate the safety and usefulness of this novel MD. Patients and Methods Consecutive patients who underwent EUS-guided hepaticogastrostomy (EUS-HGS) or EUS-guided pancreatic duct drainage (EUS-PD) at two centers were included in the study. Dilation of the needle tract was initially performed with a diathermic sheath or the ultra-tapered MD. Technical success and adverse events were assessed. Results Sixty-four patients (mean age = 68.9 ± 13.8 years, 35 men) underwent EUS-HGS (49 patients) and EUS-PD (15 patients). Thirty-three patients were included in the cautery dilator (CD) group and 31 in the ultra-tapered MD group. Initial dilation of the puncture site was achieved in 95.3% (61/64): 97% (32/33) of the patients in the CD group and 93.3% (29/31) of the patients in the MD group (P < 0.05). Adverse events were observed in 14 patients: abdominal pain in 8 patients and bleeding in 6 patients at the puncture site. All bleedings occurred in the CD group and there was no patient in whom bleeding occurred after EUS intervention in the MD group (P = 0.04). Conclusion The novel ultra-tapered MD designed for interventional EUS appears to be safe and useful as it reduced postprocedure bleeding with a high technical success rate compared with the conventional electrocautery dilator.

Abstract
Background and Objectives: Recently, a novel EUS-guided biliary drainage (EUS-BD) technique consisting of EUS-guided antegrade stenting and EUS-guided hepaticoenterostomy (EUS-AS+HES) using two conventional metal stents (MS) has been reported to decrease adverse events and maintain longer stent patency for malignant biliary obstruction (MBO). However, only a few limited reports have evaluated this technique. Finally, dedicated plastic stents (PSs) have been developed to perform EUS-HES safely. The aim of the present study was to evaluate the outcome in EUS-AS+HES for MBO using the dedicated HES PSs. Methods: The results of a total of 23 patients who underwent EUS-AS+HES (18 simultaneous cases and 5 sequential cases) for MBO from October 2014 to July 2017 were retrospectively reviewed. Results: Technical and clinical success rates were 100% (23/23). Adverse events were seen in 8.7% (2/23); 2 cases of mild biliary peritonitis, which were successfully managed conservatively. Overall survival was 96 days and the median duration of stent patency, including stent dysfunction, patient death, and last follow-up, was 66.0 days (53 days in simultaneous cases and 78 days in sequential cases). Stent dysfunction was seen in 13.0% (3/23) of patients in 267, 263, and 135 days after the procedure. Conclusions: The novel EUS-BD technique, EUS-AS using MS plus HES employing a dedicated PS, was shown to be a feasible procedure for MBO and should yield longer duration of stent patency. Furthermore, sequential antegrade stenting in cases of occluded HES seems to be one other option instead of HES stent exchange. Further large-scale comparison studies with EUS-HES or EUS-AS are required to confirm its clinical efficacy.

Abstract
Management bundles that define items or procedures strongly recommended in clinical practice have been used in many guidelines in recent years. Application of these bundles facilitates the adaptation of guidelines and helps improve the prognosis of target diseases. In Tokyo Guidelines 2013 (TG13), we proposed management bundles for acute cholangitis and cholecystitis. Here, in Tokyo Guidelines 2018 (TG18), we redefine the management bundles for acute cholangitis and cholecystitis. Critical parts of the bundles in TG18 include the diagnostic process, severity assessment, transfer of patients if necessary, and therapeutic approach at each time point. Observance of these items and procedures should improve the prognosis of acute cholangitis and cholecystitis. Studies are now needed to evaluate the dissemination of these TG18 bundles and their effectiveness. Free full articles and mobile app of TG18 are available at: http://www.jshbps.jp/modules/en/index.php?content_id=47. Related clinical questions and references are also included.

Abstract
AIM To evaluate the feasibility and reliability of endoscopic transpapillary bile duct biopsy for the diagnosis of biliary strictures.
METHODS A total of 360 patients (241 men) who underwent endoscopic retrograde cholangiopancreatography for biliary strictures with biopsy from April 2012 to March 2016 at Tokyo Medical University Hospital were retrospectively reviewed. This study was approved by our Institutional Review Board (No. 3516). Informed consent was obtained from all individual participants included in this study. The biopsy specimens were obtained using a novel slim biopsy forceps (Radial Jaw 4P, Boston Scientific, Boston, MA, United States).
RESULTS The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 69.6%, 100%, 100%, 59.1%, and 78.8%, respectively. The sensitivity was 75.6% in bile duct cancer, 64% in pancreatic cancer, 61.1% in gallbladder cancer, and 57.1% in metastasis. In bile duct cancer, a lower sensitivity was observed for perihilar bile duct stricture (68.7%) than for distal bile duct stricture (83.1%). In terms of the stricture lengths of pancreatic cancer, gallbladder cancer, and metastasis, a longer stenosis resulted in a better sensitivity. In particular, there was a significant difference between pancreatic cancer and gallbladder cancer (P < 0.05). One major complication was perforation of the extrahepatic bile duct with bile leakage.
CONCLUSION Endoscopic transpapillary biopsy alone using novel slim biopsy forceps is feasible and reliable, but restrictive. Biopsy should be performed in consideration of the stricture level, stricture length, and cancer type.

Abstract
BACKGROUND AND AIMS EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) by using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs. METHODS From July 2015 to July 2016, EUS-TD by using the new BFMS was performed in 12 patients for PFCs (4 patients with pancreatic pseudocysts, 8 patients with walled-off necrosis). When clinical resolution could not be achieved, DEN was performed the following day. RESULTS The stent was deployed successfully with a median procedure time of 16 minutes (range 11-24 minutes) and with no procedure-related adverse events in any patients (12/12, 100%). DEN via the stent was achieved in all patients in whom they were attempted (4/4,100%). Spontaneous stent migration or stent dislocation during DEN was not observed in any patients. Two WON patients died from spontaneous pseudoaneurysm rupture and multiple organ failure. The PFCs in the other 10 patients completely resolved, and later the stent was removed with no difficulty in 9 patients after a median time of 48 days (range 30-180 days). CONCLUSIONS The new BFMS is technically feasible and safe for the treatment of PFCs. (Clinical trial registration number: UMIN000021347.).

Abstract
The Tokyo Guidelines 2013 (TG13) recommend that endoscopic drainage should be the first-choice treatment for biliary decompression in patients with acute cholangitis. Timing of biliary drainage for acute cholangitis should be based on the severity of the disease. For patients with severe acute cholangitis, appropriate organ support and urgent biliary drainage are needed. For patients with moderate acute cholangitis, early biliary drainage is needed. For patients with mild acute cholangitis, biliary drainage is needed when initial treatment such as antimicrobial therapy is ineffective. There are three methods of biliary drainage: endoscopic drainage, percutaneous transhepatic drainage, and surgical drainage. Endoscopic drainage is less invasive than the other two drainage methods. The drainage method (endoscopic nasobiliary drainage and stenting) depends on the endoscopist's preference but endoscopic sphincterotomy should be selected rather than endoscopic papillary balloon dilation from the aspect of procedure-related complications. In the TG13, balloon enteroscopy-assisted and endoscopic ultrasound-guided biliary drainages have been newly added as specific drainage methods. Recent studies have demonstrated their usefulness and safety. These drainage methods will become more widespread in the future.

Abstract
Objectives: The objective of guideline was to provide clear and relevant consensus statements to form a practical guideline for clinicians on the indications, optimal technique, safety and efficacy of endoscopic ultrasound guided celiac plexus neurolysis (EUS-CPN). Methods: Six important clinical questions were determined regarding EUS-CPN. Following a detailed literature review, 6 statements were proposed attempting to answer those questions. A group of expert endosonographers convened in Chicago, United States (May 2016), where the statements were presented and feedback provided. Subsequently a consensus group of 35 expert endosonographers voted based on their individual level of agreement. A strong recommendation required 80% voter agreement. The modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria were used to rate the strength of recommendations and the quality of evidence. Results: Eighty percent agreement was reached on 5 of 6 consensus statements, 79.4% agreement was reached on the remaining one. Conclusions: EUS-CPN is efficacious, should be integrated into the management of pancreas cancer pain, and can be considered early at the time of diagnosis of inoperable disease. Techniques may still vary based on operator experience. Serious complications exist, but are rare.

Abstract
There is a lack of consensus on how endoscopic ultrasound (EUS)-guided pseudocyst drainage and endoscopic necrosectomy should be performed. This survey was carried out amongst members of the EUS Journal Editorial Board to describe their practices in performing this procedure. This was a worldwide multi-institutional survey amongst members of the EUS Journal Editorial Board in May 2017. The responses to a 22-question survey with respect to the practice of EUS-guided pseudocyst drainage and endoscopic necrosectomy were obtained. Twenty-two endoscopists responded to the questionnaire as follows: 72.7% (16/22) were of the opinion that lumen-apposing metal stents (LAMS) should be the standard of care for the creation of an endoscopic cystenterostomy in patients with pancreatic walled-off necrosis (WON); 95.5% (21/22) recommended large diameter (d=15 mm) LAMS for drainage in patients with WON; 54.5% (12/22) would not dilate LAMS after placement into the WOPN; 86.4% (19/22) would not perform endoscopic necrosectomy during the same procedure as the creation of the cystenterostomy; 45.5% (10/22) recommend that agents, such as diluted hydrogen peroxide, should be used to lavage the peri-pancreatic fluid collection (PFC) cavity in patients with WON; and 45.5% (10/22) considered a naso-cystic or other tube to be necessary for lavage of WON after initial drainage. The mean optimal interval recommended for endoscopic necrosectomy procedures after EUS-guided drainage was 6.23 days. The mean optimal interval recommended for repeat imaging in patients undergoing endoscopic necrosectomy was 12.32 days. The mean time recommended for LAMS removal was 4.59 weeks. This is the first worldwide survey on the practice of EUS-guided pseudocyst drainage and endoscopic necrosectomy. There were wide variations in practice and randomized studies are urgently needed to establish the best approach for management of this condition. There is also a pressing need to establish a best practice consensus.
