Abstract
BACKGROUND Endoscopic papillectomy (EP) is less invasive than surgery but procedure-related adverse events (AEs) still frequently occur. This study compared the benefits of EP using a new optimal endoCUT setting on the VIO (Erbe) electrosurgical unit (VIO-EP) with those using the conventional electrosurgical unit setting (ICC-EP, Erbe). METHODS This multicenter, retrospective, comparative cohort study included 57 patients who underwent VIO-EP and 91 who underwent ICC-EP. The primary outcome was occurrence of EP-related AEs. Secondary outcomes were pathological findings (the resection margins, the R0 resection, and residual lesions). RESULTS Pancreatitis tended to be less common in the VIO-EP group (5.3% vs. 9.9%, p = .248). Evaluation of computed tomography images showed that pancreatitis was confined to the pancreatic head in 77.8% of cases in the ICC-EP group and in 33.3% of those in the VIO-EP group. After exclusion of cases of delayed bleeding, pancreatitis tended to be less common in the VIO-EP group; this finding was not statistically significant (2.3% vs. 8.2%, p = .184). In pathological findings, residual lesions were significantly less common in the VIO-EP group. CONCLUSIONS The risks of pancreatitis and residual lesions after EP may be lower when the VIO electrosurgical unit is used with the optimal setting.

Abstract
Objective Few reports have explored the application of urinary trypsinogen-2 measurement in the early diagnosis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, and none have demonstrated the benefits of noninvasive testing. This study aimed to evaluate the clinical application of the rapid urinary trypsinogen-2 dipstick test (Nipro, Japan) compared with serum amylase and lipase levels for the early diagnosis of post-ERCP pancreatitis (PEP). Methods A total of 100 consecutive patients (54 men and 46 women) who were admitted and underwent ERCP at Tokyo Medical University Hospital from August 2021 to December 2021 were recruited. All patients underwent rapid urinary trypsinogen-2 measurement using the dipstick test before and after ERCP. Measurements were taken 24 h before ERCP for pre-ERCP and 1-4 h after ERCP for post-ERCP. Additionally, serum amylase and lipase levels were measured at 8:00 a.m. of the day after ERCP (at least 8 h after ERCP), and their diagnostic abilities for PEP were compared and evaluated. Results PEP occurred in 5/100 patients (5%). The sensitivity, specificity, positive predictive value, and negative predictive value of the dipstick test for diagnosing PEP were 100%, 83.2%, 23.8%, and 100%, respectively. These results were comparable to the diagnostic performance of serum amylase and lipase levels at 8:00 a.m. on the day after ERCP (at least 8 h after ERCP). However, false positives must be considered. Conclusion The dipstick test may be useful in clinical practice as a noninvasive screening test for the early prediction of PEP.

Abstract
BACKGROUND Endoscopic ultrasound-guided tissue acquisition is vital for diagnosing pancreatic and peridigestive tract lesions. A new three-prong asymmetry tip needle has been developed for this procedure. In this study, we retrospectively assessed the diagnostic ability, tissue collection volume, and procedural adverse events of the three-prong asymmetry tip needle for solid pancreatic, subepithelial, and other organ lesions. METHODS We analyzed the data of 58 consecutive patients who underwent endoscopic ultrasound-guided tissue acquisition using a three-prong asymmetry tip needle between August 2022 and April 2023 at a single care center. RESULTS The tissue collection rate was 91.4% with 89.7% accuracy, 89.3% sensitivity, 100% specificity, 100% positive predictive value, and 25% negative predictive value. No significant differences in collection rates or diagnostic performance were observed based on the target organ, puncture route, or lesion size. Using our original assessment method, the average histological core tissue score was 3.1 ± 0.8, whereas the blood contamination volume was 2.5 ± 0.8. Only one of 58 patients (1.7%) developed a pancreatic fistula of moderate severity as an adverse event. CONCLUSIONS The three-prong asymmetry tip needle demonstrated good diagnostic capability and adequate sample volume with safety for pancreatic, subepithelial, and other organ lesions.

Abstract
Objectives Endoscopic transpapillary gallbladder drainage (ETGBD) is a highly technical procedure, but few studies have evaluated factors that predict its technical success. Therefore, in this study, we sought to identify predictors of technically successful ETGBD. Methods One hundred and eighty-two patients who underwent ETGBD for acute cholecystitis at our hospital were retrospectively investigated. Factors associated with technical failure were identified by focusing on clinical characteristics, anatomical features (direction of the cystic duct branch and course of the cystic duct), and procedural factors (cystic duct and gallbladder with or without contrast and cystic duct injury). Results The technical success rate was 84.6% (154/182) and the clinical success rate was 96.1% (148/154). The adverse event rate was 11.0% (20/182; cystic duct injury in 13 patients, pancreatitis in six, and liver abscess in one. Univariate and multivariate analyses identified the right cranial direction and spiral-type course of the cystic duct to be significant anatomical features and cystic duct injury to be a significant procedural feature contributing to the technical failure of ETGBD. Conclusions ETGBD is a highly practical procedure for patients with acute cholecystitis. However, difficulty is encountered in some cases because of anatomical and procedural factors. Our results suggest that ETGBD may be difficult and thus should not be performed in cases with the right cranial direction or spiral-type course of the cystic duct or those with cystic duct injury.

Abstract
BACKGROUNDS Few data are available for surveillance decisions focusing on factors related to mortality, as the primary outcome, in intraductal papillary mucinous neoplasm (IPMN) patients. AIMS We aimed to identify imaging features and patient backgrounds associated with mortality risks by comparing pancreatic cancer (PC) and comorbidities. METHODS We retrospectively conducted a multicenter long-term follow-up of 1864 IPMN patients. Competing risk analysis was performed for PC- and comorbidity-related mortality. RESULTS During the median follow-up period of 5.5 years, 14.0% (261/1864) of patients died. Main pancreatic duct ≥5 mm and mural nodules were significantly related to all-cause and PC-related mortality, whereas cyst ≥30 mm did not relate. In 1730 patients without high-risk imaging features, 48 and 180 patients died of PC and comorbidity. In the derivation cohort, a prediction model for comorbidity-related mortality was created, comprising age, cancer history, diabetes mellitus complications, chronic heart failure, stroke, paralysis, peripheral artery disease, liver cirrhosis, and collagen disease in multivariate analysis. If a patient had a 5 score, 5- and 10-year comorbidity-related mortality is estimated at 18.9% and 50.2%, respectively, more than 7 times higher than PC-related mortality. The model score was also significantly associated with comorbidity-related mortality in a validation cohort. CONCLUSIONS This study demonstrates main pancreatic duct dilation and mural nodules indicate risk of PC-related mortality, identifying patients who need periodic examination. A comorbidity-related mortality prediction model based on the patient's age and comorbidities can stratify patients who do not require regular tests, especially beyond 5 years, among IPMN patients without high-risk features.

Abstract
BACKGROUND/PURPOSE Afferent loop syndrome (ALS) is a rare adverse event after gastrointestinal surgery requiring appropriate early decompression treatment. Several endoscopic interventions have been attempted for treatment, including endoscopic enteral metal stent placement (EMSP), endoscopic ultrasound (EUS)-guided entero-enterostomy (EUS-EE), and EUS-guided hepaticogastrostomy (EUS-HGS). However, there are limited data on outcomes, including duration of stent patency. In this study, we evaluated the usefulness of each endoscopic intervention for malignant ALS. METHODS We retrospectively investigated nine patients with malignant ALS who underwent EMSP, EUS-EE, or EUS-HGS. Information on technical success, clinical efficacy, adverse events, stent dysfunction, and overall survival was collected and analyzed. RESULTS The most common symptoms were abdominal pain and cholangitis. ALS was treated by EMSP in three patients, EUS-EE in three patients, and EUS-HGS in three patients. Stent placement was successful and clinically effective in all patients with no adverse events. During follow-up, stent dysfunction occurred in two patients treated by EUS-HGS. Eight patients died of primary disease during a median follow-up of 157 days. CONCLUSIONS Each of the available endoscopic interventions for malignant ALS can be expected to produce similar outcomes, including duration of stent patency. The choice of endoscopic intervention should be made based on the characteristics of each treatment.

Abstract
BACKGROUND/PURPOSE The aim of this study was to clarify the clinical characteristics of acute cholangitis (AC) after bilioenteric anastomosis and stent-related AC in a multi-institutional retrospective study, and validate the TG18 diagnostic performance for various type of cholangitis. METHODS We retrospectively reviewed 1079 AC patients during 2020, at 16 Tokyo Guidelines 18 (TG 18) Core Meeting institutions. Of these, the post-biliary reconstruction associated AC (PBR-AC), stent-associated AC (S-AC) and common AC (C-AC) were 228, 307, and 544, respectively. The characteristics of each AC were compared, and the TG18 diagnostic performance of each was evaluated. RESULTS The PBR-AC group showed significantly milder biliary stasis compared to the C-AC group. Using TG18 criteria, definitive diagnosis rate in the PBR-AC group was significantly lower than that in the C-AC group (59.6% vs. 79.6%, p < .001) because of significantly lower prevalence of TG 18 imaging findings and milder bile stasis. In the S-AC group, the bile stasis was also milder, but definitive-diagnostic rate was significantly higher (95.1%) compared to the C-AC group. The incidence of transient hepatic attenuation difference (THAD) and pneumobilia were more frequent in PBR-AC than that in C-AC. The definitive-diagnostic rate of PBR-AC (59.6%-78.1%) and total cohort (79.6%-85.3%) were significantly improved when newly adding these items to TG18 diagnostic imaging findings. CONCLUSIONS The diagnostic rate of PBR-AC using TG18 is low, but adding THAD and pneumobilia to TG imaging criteria may improve TG diagnostic performance.

Abstract
BACKGROUND AND AIMS Bilioenteric anastomotic stricture (BES) is a well-known adverse event after bilioenterostomy. Recently, EUS-guided antegrade intervention (EUS-AI) has been developed for cases that are difficult to treat by balloon enteroscopy-assisted ERCP. However, no data are available on the long-term outcomes after EUS-AI. The main goal of the present study was to clarify the long-term outcomes of EUS-AI in such patients. METHODS Between November 2013 and November 2021, 34 patients who were followed for more than 1 year after EUS-AI for BES were identified. The primary endpoint was the rate of stricture resolution. Secondary endpoints were factors associated with stricture resolution, rate of BES recurrence, rate of conversion to surgery, and rate of hepatic fibrosis progression during follow-up. RESULTS The median follow-up period was 56.7 months. Stricture resolution was achieved in 17 of 34 patients (50%). A multivariate analysis confirmed that the presence of bile duct stones (odds ratio, 9.473; 95% confidence interval, 1.66-53.98; P = .01) was significantly associated with stricture resolution. The stricture recurrence rate was 33%, and the median time from stent removal to recurrence was 31.2 months. Four patients underwent surgery because of recurrent cholangitis. During the median follow-up period of 56.7 months, 25% progressed to hepatic fibrosis based on the Fibrosis-4 index grade. Interestingly, patients without cholangitis during follow-up did not show progression of hepatic fibrosis. CONCLUSIONS EUS-AI has achieved acceptable long-term clinical outcomes. EUS-AI can be a viable alternative treatment of choice before surgical treatment in patients who are difficult to treat by conventional approaches.

Abstract
INTRODUCTION Endoscopic transpapillary approach by endoscopic retrograde cholangiopancreatography (ERCP) is the established technique for preoperative biliary drainage (PBD). Recently, endoscopic ultrasound-guided biliary drainage (EUS-BD) has been reported to be a useful alternative technique after ERCP fail. However, the optimal strategy remain controversial. AREA COVERED This review summarizes the literature on EUS-BD techniques for PBD with a literature search using PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials database between 2000 and 2023 using keywords for 'preoperative biliary drainage' and all types of EUS-BD techniques. EXPERT OPINION As there is no consensus on the optimal EUS-BD technique for PBD, selection of the EUS-BD approach depends on the patient's condition, the biliary obstruction site, the anastomosis after surgical intervention, and the preference of the endoscopist. However, we consider that EUS-HGS using a dedicated plastic stent may have some advantages in the adverse impact of surgical procedure because the location where the fistula is created by EUS-HGS is away from the site of the surgical procedure. Although there remain many issues that require further investigation, EUS-BD can be a feasible and safe alternative method of PBD for malignant biliary obstruction after ERCP fail.

Abstract
OBJECTIVES To clarify the clinical utility of measuring serum pancreatic enzymes after endoscopic retrograde cholangiopancreatography (ERCP) for the purpose of predicting post-ERCP pancreatitis (PEP) by a meta-analysis of diagnostic test accuracy studies. METHODS Studies on the prediction accuracy of PEP by serum amylase or lipase measured 2, 3, and 4 hours after ERCP were collected. A literature search was performed in PubMed and the Cochrane Library database for studies published between January 1980 and March 2023. The quality of individual studies was evaluated using Quality Assessment of Diagnostic Accuracy Studies-2. Data were analyzed using Meta-DiSc 2.0 software. RESULTS We searched databases and identified 20 observational studies (12,313 participants). PEPs were defined according to criteria by Cotton or modified Cotton, revised Atlanta criteria, or the Japanese criteria. Meta-analysis of 8 studies (4,389 participants) showed pooled sensitivity of 71.1% (95% confidence interval (CI): 56.1-82.5) and pooled specificity of 91.2% (95% CI: 85.9-94.6) for serum amylase cutoff value at 3 times the upper limit of normal (ULN). Another meta-analysis of 5 studies (1,970 participants) showed pooled sensitivity of 85.8% (95% CI: 61.9-95.7) and pooled specificity of 85.3% (95% CI: 81.9-88.1) for serum lipase cutoff value at 3 times ULN. DISCUSSION Despite a high risk of bias due to various reference standards, this updated meta-analysis and the utility assessment by a decision tree showed utility of serum amylase or lipase levels more than 3 times ULN measured 2 to 4 hours after ERCP for predicting PEP.

Abstract
INTRODUCTION In median arcuate ligament syndrome (MALS), the celiac artery is compressed, causing an arcade to develop in the pancreatic head, leading to ischemic symptoms and aneurysms. PATIENT CONCERNS The patient was diagnosed with borderline resectable pancreatic cancer (PC) and MALS. Endoscopic biliary drainage with a covered metal stent (CMS) was performed for the obstructive jaundice. After the jaundice improved, a modified FOLFIRINOX regimen was initiated. Several days later, cardiopulmonary arrest occurred after hematemesis occurred. Cardiopulmonary resuscitation was performed, his blood pressure stabilized, and emergent upper endoscopy was performed. The CMS was dislodged and active bleeding was observed in the papillae. The CMS was replaced, and temporary hemostasis was achieved. Contrast-enhanced computed tomography revealed a diagnosis of extravasation from the posterior superior pancreaticoduodenal artery (PSPDA) into the biliary tract. Transcatheter arterial embolization was performed. However, the patient was subsequently diagnosed with hypoxic encephalopathy and died on day 14 of hospitalization. DIAGNOSIS Biliary hemorrhage due to invasion of pancreatic cancer from the PSPDA associated with MALS. INTERVENTION None. OUTCOMES Biliary hemorrhage from the PSPDA was fatal in the patient with invasive PC with MALS. LESSONS Since MALS associated with PC is not a rare disease, the purpose of this study was to keep in mind the possibility of fatal biliary hemorrhage.

Abstract
This paper discusses a novel tube placement technique; the "spinning lasso method", in EUS-guided drainage for small pancreatic pseudocysts (PC) with video. In general, the placement of a drainage tube can be difficult in a small PC and the tube often deviates during attempted insertions into the cavity. The technique helps to mitigate this problem.

Abstract
BACKGROUND/PURPOSE A peroral cholangioscope (POCS) can allow direct visualization of the biliary mucosa and its use is becoming more widespread due to improvements in functionality, image quality, and operability, as well as the development of related devices. Recently, a novel mother-baby peroral cholangioscope (nMB-POCS) with a large (2-mm) accessory channel has been developed. In this study, we evaluated the feasibility of this novel POCS in a dry simulation and animal model. METHODS We evaluated the ease of insertion and maneuverability of the nMB-POCS, the image quality, and the passage of the devices into the accessory channel and into the common bile duct in a dry and live porcine model. RESULTS In both models, the nMB-POCS could be easily inserted into the duodenoscope and into the distal bile duct and hilum. The image quality was good, and it was possible to observe the surface structure and the vascular network of the bile duct mucosa in detail. CONCLUSIONS The nMB-POCS with its larger accessory channel is expected to improve the efficiency of diagnosis and treatment, and reduce the procedure time. Clinical studies in patients are warranted.

Abstract
Background and Objectives EUS-guided tissue acquisition is routinely performed for the diagnosis of gastrointestinal tract and adjacent organ lesions. Recently, various types of needles have been developed. However, how the shape of the needle tip and echoendoscope tip angle affect puncturability, has not been clarified. The aim of this experimental study was to compare the puncturability of several 22-gauge EUS-FNA and EUS-guided fine-needle biopsy (EUS-FNB) needles, and to evaluate the effects of the needle tip shape and echoendoscope tip angle on tissue puncturability. Materials and Methods The following six major FNA and FNB needles were evaluated: SonoTip® ProControl, EZ Shot 3 Plus, Expect™ Standard Handle, SonoTip® TopGain, Acquire™, and SharkCore™. The mean maximum resistance force against needle advancement was evaluated and compared under several conditions using an echoendoscope. Results The mean maximum resistance force of the needle alone was higher for the FNB needles than for the FNA needles. The mean maximum resistance force of the needle in the echoendoscope with free angle demonstrated that the resistance forces were between 2.10 and 2.34 Newton (N). The mean maximum resistance force increased upon increases in angle of the tip of echoendoscope, particularly in the FNA needles. Among the FNB needles, SharkCore™ had the lowest resistance force (2.23 N). The mean maximum resistance force of the needle alone, the needle in the echoendoscope with free angle, and the needle in the echoendoscope with full-up angle for SonoTip® TopGain were all similar to that of Acquire™. Conclusion SonoTip® TopGain had similar puncturability to Acquire™ in all tested situations. Regarding the puncturability, SharkCore™ is most suitable for insertion into target lesions, when tight echoendoscope tip angle is necessary.

Abstract
Urgent or emergency endoscopic retrograde cholangiopancreatography (ERCP) is indicated for gallstone-induced acute cholangitis and pancreatitis. The technique and optimal timing of ERCP depend on the disease state, its severity, anatomy, patient background, and the institutional situation. Endoscopic transpapillary biliary drainage within 24 h is recommended for moderate to severe acute cholangitis. The clinical outcomes of biliary drainage with nasobiliary drainage tube placement and plastic stent placement are comparable, and the choice is made on a case-by-case basis considering the advantages and disadvantages of each. The addition of endoscopic sphincterotomy (EST) is basically not necessary when performing drainage alone, but single-session stone removal following EST is acceptable in mild to moderate cholangitis cases without antithrombotic therapy or coagulopathy. For gallstone pancreatitis, early ERCP/EST are recommended in cases with impacted gallstones in the papilla. In some cases of gallstone pancreatitis, a gallstone impacted in the papilla has already spontaneously passed into the duodenum, and early ERCP/EST lacks efficacy in such cases, with unfavorable findings of cholangitis or cholestasis. If it is difficult to diagnose the presence of gallstones impacted in the papilla on imaging, endoscopic ultrasonography can be useful in determining the indication for ERCP.

Abstract
BACKGROUND/PURPOSE EUS-guided biliary drainage (EUS-BD) has recently been reported to be a useful salvage technique after ERCP fail. However, data on EUS-BD used for preoperative biliary drainage (PBD) are limited. The aim of this study was to verify the clinical feasibility of EUS-BD for PBD. METHODS PBD was performed for malignant biliary obstruction in 318 patients at our institution between July 2014 and April 2022. Fifteen (4.7%) of these patients underwent surgical resection after preoperative EUS-BD (HGS 13; HDS 1; AGS with HGS 1) and were retrospectively analyzed. RESULTS The stent was successfully placed in all 15 cases with a median procedure time of 15 min (technical success rate 100%). The median total bilirubin value decreased significantly from 3.7 before drainage to 0.9 after surgery (p < .001) and cholangitis was well managed (clinical success rate 100%). Surgery was performed at a median of 22 days after drainage, and there were no stent-related adverse events or recurrences of biliary obstruction. Severe surgery-related adverse events occurred in three cases, but none were associated with EUS-BD. The stent was removed during surgery in 12 cases. CONCLUSIONS EUS-BD can be a feasible and safe alternative method of PBD for malignant biliary obstruction after ERCP fail.

Abstract
Abstract
Backgrounds
Heart failure (HF) is a risk factor for new onset atrial fibrillation (AF), and the new onset AF is associated with a worse prognosis in HF patients. It has been reported that renin-angiotensin system inhibitor (RASi), β-blocker and mineral-corticoid receptor antagonist (MRA) prevent the new onset AF in HF patients. However, the effect of combined pharmacotherapy including angiotensin receptor neprilysin inhibitor (ARNI) and sodium glucose co-transporter 2 inhibitor (SGLT2i) on AF is unknown. We investigated the impact of contemporary regimen of combined pharmacotherapy for HF (RASi/ARNI+β-blocker+MRA+SGLT2i) on new onset AF.
Methods and results
We retrospectively studied rEF and mrEF patients without AF admitted to our hospital due to decompensated HF between 2015 and 2021 (n=366). Long-term (The mean follow-up was 635±421 days) incidence of new onset AF was investigated with regard to medical therapies. Patients were divided into 2 groups; patients with ≤2 HF drugs (n=181) and patients with ≥3 HF drugs (n=185). Patients with ≤2 HF drugs group were older (77.3 vs 67.0 years old, P<0.001), had a poorer renal function (Cre: 1.66 vs 1.09 mg/dl, P<0.001), and had a higher rate of ischemic heart disease (52 vs 38%, P=0.009), whereas left ventricular systolic function was better (EF: 31.9 vs 27.3%, P<0.001). There were 19 (10.5%) new onsets AF in the ≤2 HF drugs group, whereas only 7 (3.8%) had new onsets AF in the ≥3 HF drugs group (HR 0.36, 95% CI 0.15–0.85, P=0.01). All-cause death and hospitalization for HF were fewer in the ≥3 HF drugs group. A multivariate analysis revealed that ≥3 HF drugs use was an independent negative predictor of new onset AF (HR 0.37, 95% CI 0.15–0.93, P=0.03). Even after a propensity score matching of the clinical variables, the incidence of new onset AF was consistently fewer in the ≥3 HF drugs group (HR 0.36, 95% CI 0.13–0.99, P=0.04). Finally, patients with new onset AF had a higher rate of hospitalization for HF in the studied population (HR 9.68, 95% CI 5.67–16.5, P<0.01).
Conclusion
Aggressive combined pharmacotherapy for HF may be associated with fewer new onset AF in patients with HF.

Abstract
We herein report two cases of hemorrhagic ampullary lesions in which endoscopic papillotomy was performed to control bleeding and resulted in successful treatment. Both patients were pathologically diagnosed with an underlying pathology characterized by inflammatory cell infiltration and capillary proliferation. They also had disposing factors for bleeding, such as antithrombotic therapy and idiopathic thrombocytopenic purpura. Endoscopic treatment was selected because the risk of surgical resection was high due to the patients' hemorrhagic condition. Both patients were successfully treated without any serious adverse events and had an uneventful postoperative course with no relapse of bleeding.

Abstract
Pancreatic cancer (PC) has one of the poorest prognoses among solid cancers, and its incidence has increased recently. Satisfactory outcomes are not achieved with current therapies; thus, novel treatments are urgently needed. High-intensity focused ultrasound (HIFU) is a novel therapy for ablating tissue from the outside of the body by focusing ultrasonic waves from multiple sources on the tumor. In this therapy, only the focal area is heated to 80-100 ºC, which causes coagulative necrosis of the tissue, with hardly any impact on the tissue outside the focal area. Although HIFU is a minimally invasive treatment and is expected to be useful, it is not yet generally known. Here, we discuss the usefulness of HIFU treatment for un-resectable advanced PC using the results of previous research, meta-analyses, and systematic reviews on its efficacy and safety. HIFU therapy for un-resectable PC is useful for its anti-tumor effect and pain relief, and is expected to prolong survival time and improve quality of life. Although HIFU for PC has several limitations and further study is needed, this technique can be safely performed on un-resectable advanced PC. In future, HIFU could be utilized as a minimally invasive treatment strategy for PC patients with a poor prognosis.

Abstract
BACKGROUND In preparing the Japanese (JPN) guidelines for the management of acute pancreatitis 2021, the committee focused the issues raised by the results of nationwide epidemiological survey in 2016 in Japan METHOD: In addition to a systematic search using the previous JPN guidelines, papers published from January 2014 to September 2019 were searched for the contents to be covered by the guidelines based on the concept of GRADE system. RESULTS Thirty-six clinical questions (CQ) were prepared in 15 subject areas. Base on the facts that patients diagnosed with severe disease by both Japanese prognostic factor score and contrast-enhanced CT grade had a high fatality rate and that little prognosis improvement after 2 weeks of disease onset was not obtained, we emphasized the importance of Pancreatitis Bundles, which was shown to be effective in improving prognosis, and the CQ sections for local pancreatic complications had been expanded to ensure adoption of a step-up approach. Furthermore, on the facts that enteral nutrition for severe acute pancreatitis was not started early within 48 hours of admission and that unnecessary prophylactic antibiotics was used in almost all cases, we emphasized early enteral nutrition in small amounts even if gastric feeding is used and no prophylactic antibiotics in mild pancreatitis. CONCLUSION All the members of the committee have put a lot of effort into preparing the extensively revised guidelines in the hope that more people will have a common understanding and that better medical care will be spread.

Abstract
BACKGROUND AND AIMS The optimal electrosurgical unit (ESU) settings for endoscopic papillectomy (EP) have not been investigated. We conducted animal experiments to determine the optimal endoCUT settings with VIO (Erbe, Tübingen, Germany) ESUs and then conducted a small clinical study. METHODS Dedicated animal experimental models were created. To investigate the incision force, chicken meat was resected with a snare whose handle was a hung weight. To investigate the coagulation effect, a surgical needle electrode was inserted into a pig liver and energized, and to determine changes over time in the coagulation status, simulated EP was performed using a living pig. These experiments were performed using the knife-setting or snare-setting endoCUT modes and various effect, duration, and interval settings and compared with results for ICC (Erbe) ESUs. Based on the results, we performed EP in a small number of patients. RESULTS The main factor affecting the incision force was duration. The coagulation effect was related to not only effect but also duration. In the endoCUT mode, knife-setting produced a higher incision force and lower coagulation effect. The nondischarge coagulation effect may cause deep ulceration. Based on the animal experiments, we concluded the ideal ESU setting for EP, "VIO EP mode," is knife-setting with high duration, lowest effect, and low interval settings. In the clinical study, there were no significant adverse events such as bleeding, pancreatitis, or perforation. CONCLUSIONS "VIO EP mode" seems to afford optimal papillectomy. Larger scale clinical studies are needed to accumulate further data and make clinical comparisons with the ICC ESU.

Abstract
BACKGROUND/PURPOSE Although the lumen-apposing metal stent (LAMS) is useful for interventional endoscopic ultrasound (EUS) procedures, there has been some concern about the potential for stent-induced adverse events because of the high lumen-apposing force. A newly designed LAMS with less lumen-apposing force has been developed for use with a physician-controlled electrocautery-enhanced delivery system. The aim of this animal study was to evaluate the feasibility of performing interventional EUS using this newly designed LAMS system. METHODS EUS-guided cystogastrostomy was performed using the novel LAMS 3 times in a wet simulation model. EUS-guided gastroenterostomy and EUS-guided gallbladder drainage were then performed using the system in 4 pigs. RESULTS The LAMS was successfully placed in all 3 EUS-guided cystogastrostomy procedures using the wet simulation model and in all 4 EUS-guided gastroenterostomy and gallbladder drainage procedures in the animal model. In the 3 weeks following the procedure, eating behavior was normal in all animals and there were no adverse events. The stents remained patent during this time and were removed without difficulty. The fistula was mature in all cases and a standard upper gastrointestinal endoscope was easily advanced via the fistula to observe the afferent and efferent loops or the lumen of the gallbladder. Necropsy confirmed complete adhesion between the stomach and the wall of the jejunum or gallbladder. CONCLUSIONS Our study findings demonstrate the feasibility of this new LAMS system and its potential clinical value for interventional EUS.

Abstract
Background and Objectives: Several studies have demonstrated that EUS-guided fine-needle biopsy (EUS-FNB) is useful for diagnosing gastrointestinal subepithelial lesions (GI SELs). However, there is limited evidence regarding the use of Franseen needles during EUS-FNB for patients with GI SELs. In addition, the optimal approach for diagnosing small SELs is unclear. This study aimed to evaluate whether EUS-FNB using a Franseen needle was effective for diagnosing GI SELs, including small lesions. Methods: Between January 2013 and January 2020, 150 consecutive patients with GI SELs underwent EUS-FNA/FNB to achieve a histological diagnosis. Eighty-six consecutive patients who underwent EUS-FNB using a Franseen needle were compared to 64 patients who underwent EUS-FNA using a conventional needle. Results: The diagnostic yield was significantly higher using a Franseen needle than using a conventional needle (85% vs. 75%, P = 0.006). Furthermore, in cases with SELs that were <20 mm, the diagnostic yield was significantly higher using a Franseen needle than using a conventional needle (81% vs. 45%; P = 0.003). Multivariate analysis revealed that obtaining a sufficient diagnostic sample was independently predicted by Franseen needle use (adjusted odds ratio: 2.8, 95% confidence interval: 1.2–6.3; P = 0.01) and tumor size of >20 mm (adjusted odds ratio: 3.4, 95% confidence interval: 1.4–8.2; P = 0.006). Conclusion: Even when attempting to diagnose small GI SELs, EUS-FNB using a Franseen needle appears to provide a more efficient acquisition of true histological core tissue than using a conventional needle.

Abstract
Campylobacter jejuni is common cause of enteritis, but biliary infection rarely reported. An 82-year-old woman with pancreatic head cancer underwent endoscopic biliary drainage for malignant biliary obstruction. She was subsequently admitted for management of diarrhea. C. jejuni was identified in stool culture. Her symptoms resolved temporarily without antibiotics but flared up with a fever a few days later. She was diagnosed with acute cholangitis and bacteremia with C. jejuni. Endoscopic biliary drainage and antimicrobial administration improved her symptoms. As complications of C. jejuni diarrhea are rare, antibiotics are not necessarily indicated but sometimes are needed to prevent complications.

Abstract
BACKGROUND/PURPOSE Various tumors of the minor duodenal papilla have been reported, most of which are treated by laparotomy. Although early-stage tumors of the major papilla are increasingly being treated by endoscopic resection with relative ease and low invasiveness, there are only a few reports on endoscopic resection of tumors in the minor papilla. METHODS Six patients with tumors in the minor papilla were treated by endoscopic papillectomy (EP), and their clinical and histopathological data were analyzed retrospectively. RESULTS The final pathological diagnoses were carcinoma in adenoma in two patients and adenoma, neuroendocrine neoplasm (G1), hyperplastic lesion, and no neoplastic lesion (disappearance of adenoma after biopsy) in one patient each. En bloc resection was performed in five patients and piecemeal resection in one patient. There were no procedure-related adverse events, such as bleeding, pancreatitis, or perforation. There was one case with a residual lesion, which was treated by ablation therapy, and no recurrences during a mean follow-up of 12 ± 10.33 months (maximum, 28 months) from the date of EP. CONCLUSIONS Endoscopic papillectomy appears to be an effective minimally invasive treatment for ampullary tumors of the minor duodenal papilla.

Abstract
High-intensity focused ultrasound (HIFU) is a novel advanced therapy for unresectable pancreatic cancer (PC). HIFU therapy with chemotherapy is being promoted as a novel method to control local advancement by tumor ablation. We evaluated the therapeutic effects of HIFU therapy in locally advanced and metastatic PC. PC patients were treated with HIFU as an optional local therapy and systemic chemotherapy. The FEP-BY02 (Yuande Bio-Medical Engineering) HIFU device was used under ultrasound guidance. Of 176 PC patients, 89 cases were Stage III and 87 were Stage IV. The rate of complete tumor ablation was 90.3%, while that of symptom relief was 66.7%. The effectiveness on the primary lesions were as follows: complete response (CR): n = 0, partial response (PR): n = 21, stable disease (SD): n = 106, and progressive disease (PD): n = 49; the primary disease control rate was 72.2%. Eight patients underwent surgery. The median survival time (MST) after diagnosis for HIFU with chemotherapy compared to chemotherapy alone (100 patients in our hospital) was 648 vs. 288 days (p < 0.001). Compared with chemotherapy alone, the combination of HIFU therapy and chemotherapy demonstrated significant prolongation of prognosis. This study suggests that HIFU therapy has the potential to be a novel combination therapy for unresectable PC.
