RESUMEN

BACKGROUND AND AIMS: We compared ERCP using a balloon-assisted endoscope (BE-ERCP) with EUS-guided antegrade treatment (EUS-AG) for removal of common bile duct (CBD) stones in patients with Roux-en-Y (R-Y) gastrectomy. METHODS: Consecutive patients who had previous R-Y gastrectomy undergoing BE-ERCP or EUS-AG for CBD stones in 16 centers were retrospectively analyzed. RESULTS: BE-ERCP and EUS-AG were performed in 588 and 59 patients, respectively. Baseline characteristics were similar, except for CBD diameter and angle. The technical success rate was 83.7% versus 83.1% (P = .956), complete stone removal rate was 78.1% versus 67.8% (P = .102), and early adverse event rate was 10.2% versus 18.6% (P = .076) in BE-ERCP and EUS-AG, respectively. The mean number of endoscopic sessions was smaller in BE-ERCP (1.5 ± .8 vs 1.9 ± 1.0 sessions, P = .01), whereas the median total treatment time was longer (90 vs 61.5 minutes, P = .001). Among patients with biliary access, the complete stone removal rate was significantly higher in BE-ERCP (93.3% vs 81.6%, P = .009). Negative predictive factors were CBD diameter ≥15 mm (odds ratio [OR], .41) and an angle of CBD <90 degrees (OR, .39) in BE-ERCP and a stone size ≥10 mm (OR, .07) and an angle of CBD <90 degrees (OR, .07) in EUS-AG. The 1-year recurrence rate was 8.3% in both groups. CONCLUSIONS: Effectiveness and safety of BE-ERCP and EUS-AG were comparable in CBD stone removal for patients after R-Y gastrectomy, but complete stone removal after technical success was superior in BE-ERCP.

RESUMEN

The progress of endoscopic diagnosis and treatment for inflammatory diseases of the biliary tract and pancreas have been remarkable. Endoscopic ultrasonography (EUS) and EUS-elastography are used for the diagnosis of early chronic pancreatitis and evaluation of endocrine and exocrine function in chronic pancreatitis. Notably, extracorporeal shock wave lithotripsy and electrohydraulic shock wave lithotripsy have improved the endoscopic stone removal rate in patients for whom pancreatic stone removal is difficult. Studies have reported the use of self-expanding metal stents for stent placement for pancreatic duct stenosis and EUS-guided pancreatic drainage for refractory pancreatic duct strictures. Furthermore, EUS-guided drainage using a double-pigtailed plastic stent has been performed for the management of symptomatic pancreatic fluid collection after acute pancreatitis. Recently, lumen-apposing metal stents have led to advances in the treatment of walled-off necrosis after acute pancreatitis. EUS-guided biliary drainage is an alternative to refractory endoscopic biliary drainage and percutaneous transhepatic biliary drainage for the treatment of acute cholangitis. The placement of an inside stent followed by switching to uncovered self-expanding metal stents in difficult-to-treat cases has been proposed for acute cholangitis by malignant biliary obstruction. Endoscopic transpapillary gallbladder drainage is an alternative to percutaneous transhepatic gallbladder drainage for severe and some cases of moderate acute cholecystitis. EUS-guided gallbladder drainage has been reported as an alternative to percutaneous transhepatic gallbladder drainage and endoscopic transpapillary gallbladder drainage. However, it is important to understand the advantages and disadvantages of each drainage method and select the optimal drainage method for each case.

RESUMEN

The consensus-based TOKYO criteria were proposed as a standardized reporting system for endoscopic transpapillary biliary drainage. The primary objective was to address issues arising from the inconsistent reporting of stent outcomes across studies, which has complicated the comparability and interpretation of study results. However, the original TOKYO criteria were not readily applicable to recent modalities of endoscopic biliary drainage such as biliary drainage based on endoscopic ultrasound or device-assisted endoscopy. There are increasing opportunities for managing hilar biliary obstruction and benign biliary strictures through endoscopic drainage. Biliary ablation has been introduced to manage benign and malignant biliary strictures. In addition, the prolonged survival times of cancer patients have increased the importance of evaluating overall outcomes during the period requiring endoscopic biliary drainage rather than solely focusing on the patency of the initial stent. Recognizing these unmet needs, a committee has been established within the Japan Gastroenterological Endoscopy Society to revise the TOKYO criteria for current clinical practice. The revised criteria propose not only common reporting items for endoscopic biliary drainage overall, but also items specific to various conditions and interventions. The term "stent-demanding time" has been defined to encompass the entire duration of endoscopic biliary drainage, during which the overall stent-related outcomes are evaluated. The revised TOKYO criteria 2024 are expected to facilitate the design and reporting of clinical studies, providing a goal-oriented approach to the evaluation of endoscopic biliary drainage.

RESUMEN

This study investigated the trends in idiopathic peptic ulcers, examined the characteristics of refractory idiopathic peptic ulcer, and identified the optimal treatment. The characteristics of 309 patients with idiopathic peptic ulcer were examined. We allocated idiopathic peptic ulcers that did not heal after 8 weeks' treatment (6 weeks for duodenal ulcers) to the refractory group and those that healed within this period to the healed group. The typical risk factors for idiopathic peptic ulcer (atherosclerosis-related underlying disease or liver cirrhosis complications) were absent in 46.6% of patients. Absence of gastric mucosal atrophy (refractory group: 51.4%, healed group: 28.4%; p = 0.016), and gastric fundic gland polyps (refractory group: 17.6%, healed group: 5.9%; p = 0.045) were significantly more common in the refractory group compared to the healed group. A history of H. pylori eradication (refractory group: 85.3%, healed group: 66.0%; p = 0.016), previous H. pylori infection (i.e., gastric mucosal atrophy or history of H. pylori eradication) (refractory group: 48.5%, healed group: 80.0%; p = 0.001), and potassium-competitive acid blocker treatment (refractory group: 28.6%, healed group, 64.1%; p = 0.001) were significantly more frequent in the healed group compared to the refractory group. Thus, acid hypersecretion may be a major factor underlying the refractoriness of idiopathic peptic ulcer.

RESUMEN

BACKGROUND AND AIM: Small gastric subepithelial lesions (SELs) are sometimes encountered in daily esophagogastroduodenoscopy (EGD) practice, but whether once-annual or twice-annual endoscopy can provide sufficient follow-up remains unclear. Because follow-up based on small-SEL characteristics is important, this study clarified the natural history of gastric SELs less than 20 mm. METHODS: This retrospective multicenter observation study conducted at 24 Japanese hospitals during April 2000 to March 2020 examined small gastric SELs of ≤20 mm diameter. The primary outcome was the rate of size increase of those SELs detected using EGD, with growth times assessed irrespective of SEL pathological diagnoses. RESULTS: We examined 824 cases with tumors of 1-5 mm diameter in 298 (36.2%) cases, 6-10 mm in 344 (41.7%) cases, 11-15 mm in 112 (13.6%) cases, and 16-20 mm in 70 (8.50%) cases. An increase of small gastric SELs was observed in 70/824 patients (8.5%). The SELs larger than 6 mm increased, even after 10 years. No-change and increasing groups had no significantly different malignant findings at diagnosis. In cases of gastrointestinal stromal tumors (GISTs), internal cystic change in endoscopic ultrasound (EUS) is a risk factor for an increased tumor size. The predictive tumor growth cutoff size at initial diagnosis was 13.5 mm. CONCLUSIONS: Small gastric SELs less than 20 mm have an approximately 8.5% chance of increase. Predictive markers for GIST growth are tumor size ≥13.5 mm and internal cystic change in EUS.

RESUMEN

OBJECTIVES: We aimed 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 at 2, 3, and 4 h 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 the Quality Assessment of Diagnostic Accuracy Studies-2. Data were analyzed using Meta-DiSc 2.0 software. RESULTS: We searched the 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 eight studies (4389 participants) showed a 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 the serum amylase cut-off value at 3 times the upper limit of normal (ULN). Another meta-analysis of five studies (1970 participants) showed a pooled sensitivity of 85.8% (95% CI 61.9-95.7) and pooled specificity of 85.3% (95% CI 81.9-88.1) for the serum lipase cut-off value at 3 times ULN. CONCLUSION: Despite a high risk of bias due to various reference standards, this updated meta-analysis and the utility assessment by a decision tree showed the utility of serum amylase or lipase levels more than 3 times ULN measured 2-4 h after ERCP for predicting PEP.

RESUMEN

BACKGROUND AND AIMS: Although single-balloon enteroscopy (SBE)-assisted or short-type SBE (short SBE)-assisted ERCP has been reported as useful in patients with surgically altered anatomy, most studies had small sample sizes or single-center designs. This study aimed to evaluate the efficacy and factors affecting the procedure results of short SBE-assisted ERCP in patients with surgically altered anatomy. METHODS: This multicenter, retrospective study was conducted at 8 tertiary referral care centers in Japan. The data of patients who underwent ERCP-related procedures using short SBE between September 2011 and August 2019 at each facility were analyzed. RESULTS: Overall, 1318 patients were included in this analysis. The enteroscopy (reaching the target site), cannulation, and total procedural success rates were 87.9% (95% confidence interval [CI], 86.1%-89.6%), 87.0% (95% CI, 84.9%-88.8%), and 74.9% (95% CI, 72.5%-77.2%), respectively. Adverse events occurred in 7.7% of patients (95% CI, 6.4%-9.3%). Multiple logistic regression analysis indicated that age (≥75 years), Roux-en-Y reconstruction, pancreatic indication, and malignancy were factors affecting the total procedural failure. CONCLUSIONS: This large-scale study proved that short SBE-assisted ERCP in patients with surgically altered anatomy was effective. Moreover, it clarified factors affecting procedure results. Proficiency with alternative treatment techniques is required in difficult cases. (Clinical trial registration number: UMIN00004045.).

RESUMEN

AIM: The purpose of this study was to examine the effect of pemafibrate (PEM) in primary biliary cholangitis (PBC) patients with dyslipidemia. METHODS: Patients who were diagnosed with PBC between June 2018 and December 31, 2020 were included in the study if they also had dyslipidemia and their alkaline phosphatase (ALP) or gamma-glutamyl transferase (GGT) levels remained above the normal range despite taking 600 mg/day ursodeoxycholic acid (UDCA) for at least 6 months. Patients who were treated with UDCA alone were administered PEM as an add-on (PEM-add group), and patients who were treated with UDCA and bezafibrate (BEZ) for at least 6 months were given PEM instead of BEZ (PEM-switch group). Clinical parameters were compared in all patients, and the levels of ALP, GGT, the estimated glomerular filtration rate (eGFR), and creatinine (Cr) were compared between the PEM-add and PEM-switch groups. Improvement in cholangitis was also evaluated. RESULTS: In the PEM-add group, both ALP and GGT improved in 40 of 46 patients (87.0%). In the PEM-switch group, both ALP and GGT improved in 15 of 29 patients (51.7%). In the PEM-switch group, however, significant improvement was seen in eGFR and Cr. CONCLUSIONS: Administration of PEM is effective in PBC patients with dyslipidemia who are refractory to UDCA monotherapy. In patients using both UDCA and BEZ, there was an advantage in switching to PEM if they had renal damage; however, improvement of ALP and GGT occurred in about 50%.

RESUMEN

INTRODUCTION: Hematochezia is observed frequently in daily practice. However, natural hemostasis often prevents identification of the bleeding source during observations. This study was conducted to clarify risk factors related to rebleeding in hematochezia patients without an identified cause of bleeding. METHODS: We analyzed patients who were admitted to Dokkyo Medical University Hospital during April 1, 2009, through March 31, 2015, with the chief complaint of hematochezia. Main outcome measures included the rebleeding rate and the period until rebleeding in hematochezia patients without an identified bleeding source. RESULTS: We selected 159 patients for analyses. Rebleeding was observed in 46 (28.9%) of 159 patients. The median period until first rebleeding was 166 days (2-3,046 days). Univariate analysis indicated that risk factors for rebleeding were male gender (p = 0.029), higher age (p = 0.023), antithrombotic medicines (p = 0.047), lower hemoglobin on admission (p = 0.024), and the presence of diverticula (p = 0.002). Multivariate analysis indicated the presence of diverticula (p = 0.023) and male gender (p = 0.043) as rebleeding risk factors. DISCUSSION/CONCLUSION: In patients with hematochezia of unknown origin, risk factors for rebleeding indicated in this study, especially the presence of diverticula and male gender, should be given particular attention by physicians.

RESUMEN

OBJECTIVES: Ultrasound speed (USS) correction improves image quality by estimating the optimal USS correcting the deviation from a predetermined USS. This study assessed USS differences between chronic pancreatitis (CP), early CP (ECP), and normal pancreas when using endoscopic ultrasound (EUS). The usefulness of measuring optimal USS was evaluated for patients with CP, including early stage patients. METHODS: This study enrolled 116 consecutive patients for whom USS was measured using an EUS system. The USS correction principle is generation of a B-mode image by changing the USS in all ranges while correcting the delay in the received data. Final diagnoses were made according to the Japanese diagnostic criteria for CP in 2019. They were classified as CP, ECP, or normal. We compared USS applied for these three groups. RESULTS: The medians and ranges of USS values for patients in the normal, ECP, and CP groups were 1506.0 (1407-1600) m/s, 1580.0 (1520-1630) m/s, and 1574.0 (1537-1610) m/s, respectively. The USS values of the ECP and CP groups were significantly higher than those of the normal group (P < 0.001). Analyses of the receiver operating characteristic curve in the normal pancreas, ECP, and CP revealed the area as 0.957, with specificity and sensitivity of 95.9% and 87.5%, respectively, using the USS of 1535 m/s as a cut-off. CONCLUSION: Measurement of USS might be particularly useful for distinguishing between normal and ECP imaging.

RESUMEN

A 41-year-old man was treated with prednisolone (PSL) and multimatrix (MMX) mesalamine for remission induction therapy of ulcerative colitis. PSL was tapered due to successful remission induction treatment. During the treatment course, ocular foreign body sensation, eyelid swelling, ocular conjunctiva hyperemia, facial redness and swelling, watery nasal discharge, stomatitis, anal pain, and reddish puffiness on the bilateral dorsum of the hands appeared, and he was diagnosed with Stevens-Johnson syndrome (SJS). SJS was improved by PSL treatment and intravenous immunoglobulin. MMX mesalamine was the causative agent by drug-induced lymphocyte stimulation test. This is the first reported case of SJS with MMX mesalamine.

RESUMEN

A 60-year-old woman was diagnosed with nonfunctional pancreatic neuroendocrine neoplasm with multiple liver metastases and was administered everolimus. Due to persistent epigastric pain and diarrhea, a colonoscopy was performed on the 14th day after the start of everolimus administration, which revealed small bleeding ulcers in the ileocecal region, transverse colon, and rectum. These adverse effects were attributed to the everolimus; it was immediately discontinued, and the patient's clinical symptoms and imaging findings improved. We concurred that the administration of calcium channel blockers resulted in the inhibition of everolimus metabolism and the disease onset. The everolimus was discontinued. There was no subsequent recurrence of hemorrhagic colitis.

RESUMEN

BACKGROUND: The diagnosis of chronic pancreatitis (CP) using endoscopic ultrasound (EUS) criteria, referred to as the Rosemont classification (RC), has been widely performed. However, the validity of the RC, which was based on expert opinion, is still controversial. If EUS findings are associated with CP, then they should be associated with risk factors for CP. In this study, to verify the appropriateness of the RC and each EUS finding, we performed a retrospective analysis from the viewpoint of risk factors for CP. SUMMARY: Three hundred and forty-four patients were enrolled in this study. Clinical background characteristics that associate with CP were alcohol intake, smoking, history of acute pancreatitis (AP), and age. The correlation between EUS criteria for CP and clinical background was investigated. All EUS findings except the presence of cysts showed significant correlations with one or 2 of the 3 following factors: ethanol (EtOH) intake, smoking status, and history of AP. Results of the univariate and multivariate analyses showed that 3 factors (EtOH intake, smoking, and history of AP) other than age were positively correlated with the RC. Moreover, the risk of progression from normal to consistent CP to indeterminate and suggestive CP was found to increase with increasing EtOH intake. Key Messages: The RC and each EUS finding was validated from the viewpoint of risk factors for CP.

RESUMEN

INTRODUCTION: A few reports stating that differences in the various types of contrast media injected into the pancreatic duct are related to the onset of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) have been published, and it was indicated that iodixanol which is a nonionic iodide radiographic contrast medium with a dimeric (2 dimers) structure may reduce the incidence of PEP. The aim of this retrospective study is to evaluate the usefulness of iodaxanol for prevention PEP in comparison with megulamine amidototrizoate. METHODS: Two hundred and ninety-one patients were enrolled and divided into the 2 groups according to the contrast medium used. One hundred and fifty-five patients underwent ERCP with meglumine amidotrizoate, and 136 patients underwent ERCP with iodaxanol. The primary outcome of this study was the incidence of PEP associated with the use of each contrast medium. RESULTS: In this study, comparison of the meglumine amidotrizoate treatment and iodaxanol treatment groups showed no significant difference with respect to the incidence of PEP. In addition, there was also no difference between the groups with respect to PEP severity. CONCLUSION: Our study suggested that iodaxanol does not necessarily contribute to the prevention of PEP in comparison with meglumine amidotrizoate.

RESUMEN

Sedation in gastroenterological endoscopy has become an important medical option in routine clinical care. Here, the Japan Gastroenterological Endoscopy Society and the Japanese Society of Anesthesiologists together provide the revised "Guidelines for sedation in gastroenterological endoscopy" as a second edition to address on-site clinical questions and issues raised for safe examination and treatment using sedated endoscopy. Twenty clinical questions were determined and the strength of recommendation and evidence quality (strength) were expressed according to the "MINDS Manual for Guideline Development 2017." We were able to release up-to-date statements related to clinical questions and current issues relevant to sedation in gastroenterological endoscopy (henceforth, "endoscopy"). There are few reports from Japan in this field (e.g., meta-analyses), and many aspects have been based only on a specialist consensus. In the current scenario, benzodiazepine drugs primarily used for sedation during gastroenterological endoscopy are not approved by national health insurance in Japan, and investigations regarding expense-related disadvantages have not been conducted. Furthermore, including the perspective of beneficiaries (i.e., patients and citizens) during the creation of clinical guidelines should be considered. These guidelines are standardized based on up-to-date evidence quality (strength) and supports on-site clinical decision-making by patients and medical staff. Therefore, these guidelines need to be flexible with regard to the wishes, age, complications, and social conditions of the patient, as well as the conditions of the facility and discretion of the physician.

RESUMEN

BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is used for the histopathological diagnosis of any type of gastrointestinal disease. Few adverse events are experienced with this procedure; however, the actual rate of adverse events remains unclear. This study aimed to clarify the current status of cases that experienced adverse events related to the EUS-FNA procedure used for histopathologic diagnoses. METHODS: A retrospective analysis of cases with EUS-FNA-related adverse events in Japanese tertiary centers was conducted by assessing the following clinical data: basic case information, FNA technique, type of procedural adverse events, and prognosis. RESULTS: Of the 13,566 EUS-FNA cases overall, the total number of cases in which adverse events related to EUS-FNA occurred was 234. The incidence of EUS-FNA-related adverse events was ~1.7%. Bleeding and pancreatitis cases accounted for ~49.1% and 26.5% of all adverse events, respectively. Bleeding was the most common adverse event with only seven cases requiring blood transfusion. In cases with neuroendocrine tumors, pancreatitis was the most frequent adverse event. Needle tract seeding because of EUS-FNA was observed during the follow-up period in only ~0.1% of cases with pancreatic cancer. There was no mortality because of adverse events caused by EUS-FNA. CONCLUSIONS: This study revealed that the adverse events-related EUS-FNA for histopathologic diagnoses were not severe conditions, and had low incidence.

RESUMEN

BACKGROUND: Chronic pancreatitis (CP) is a complex inflammatory disease with variable presentations and outcomes. This statement is part of the international consensus guidelines on CP, specifically on the diagnostic role of endoscopic ultrasound (EUS). METHODS: An international working group with experts on the role of diagnostic EUS in the management of CP from the major pancreas societies (IAP, APA, JPS, and EPC) evaluated two key statements generated from evidence on two questions deemed to be the most clinically relevant. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to evaluate the level of evidence available for each statement. To determine the level of agreement, the working group voted on each statement for strength of agreement, using a nine-point Likert scale in order to calculate Cronbach's alpha reliability coefficient. RESULTS: Strong consensus was obtained for both of the following statements [1]. The ideal threshold number of EUS criteria necessary to diagnose CP has not been firmly established, but the presence of 5 or more and 2 or less strongly suggests or refutes the diagnosis, respectively. The Rosemont scoring system standardizes the reporting of EUS signs indicative of chronic pancreatitis, but further studies are needed to demonstrate an overall improvement of its diagnostic accuracy over conventional scoring [2]. Specificity, inter- and intra-observer variability and pre-test probability limit the reliability and utility of EUS to help diagnose CP especially early stages of the disease. CONCLUSIONS: The presence of 5 or more and 2 or less EUS criteria strongly suggests or refutes the diagnosis of CP, respectively. Intra-observer variability still limits the role of EUS in diagnosing CP especially early stage disease.

RESUMEN

BACKGROUND/OBJECTIVES: This paper is part of the international consensus guidelines on chronic pancreatitis, presenting for interventional endoscopy. METHODS: An international working group with experts on interventional endoscopy evaluated 26 statements generated from evidence on 9 clinically relevant questions. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to evaluate the level of evidence. To determine the level of agreement, a nine-point Likert scale was used for voting on the statements. RESULTS: Strong consensus was obtained for 15 statements relating to nine questions including the recommendation that endoscopic intervention should be offered to patients with persistent severe pain but not to those without pain. Endoscopic decompression of the pancreatic duct could be used for immediate pain relief, and then offered surgery if this fails or needs repeated endoscopy. Endoscopic drainage is preferred for portal-splenic vein thrombosis and pancreatic fistula. A plastic stent should be placed and replaced 2-3 months later after insertion. Endoscopic extraction is indicated for stone fragments remaining after ESWL. Interventional treatment should be performed for symptomatic/complicated pancreatic pseudocysts. Endoscopic treatment is recommended for bile duct obstruction and afterwards surgery if this fails or needs repeated endoscopy. Surgery may be offered if there is significant calcification and/or mass of the pancreatic head. Percutaneous endovascular treatment is preferred for hemosuccus pancreaticus. Surgical treatment is recommended for duodenal stenosis due to chronic pancreatitis. CONCLUSIONS: This international expert consensus guideline provides evidenced-based statements concerning indications and key aspects for interventional endoscopy in the management of patients with chronic pancreatitis.

RESUMEN

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

RESUMEN

The development of endoscopic treatment for pancreatobiliary diseases in recent years is remarkable. In addition to conventional transpapillary treatments under endoscopic retrograde cholangiopancreatography (ERCP), new endoscopic ultrasound-guided therapy is being developed and implemented. On the other hand, due to the development/improvement of various devices such as new metal stents, a new therapeutic strategy under ERCP is also advocated. The present review focuses on recent advances in the endoscopic treatment of pancreatic pseudocysts, walled-off necrosis, malignant biliary strictures, and benign biliary/pancreatic duct strictures.
