Endoscopic ultrasound (EUS)-guided therapeutic procedures have become increasingly common in clinical practice. The development of EUS-guided fine needle aspiration cytology led to the concept of interventional EUS. However, it carries a considerable risk of adverse events (AEs), which occur in approximately 23% of the procedures performed for the drainage of pancreatic fluid collections and 2.5-37.0% of those performed for drainage of the biliary tract. Although the vast majority of AEs occurring after EUS-guided drainage are mild, a deep understanding of such events is necessary for their appropriate management. Because EUS-guided drainage is a novel procedure, there have been few studies of the topic. To our knowledge, this is the first narrative review that focuses on the management and resolution of AEs occurring after EUS-guided drainage of pancreatic fluid collections or the biliary tract. We also include an explanatory video.

BACKGROUND: Many studies evaluated magnification endoscopy (ME) to correlate changes on the gastric mucosal surface with Helicobacter pylori (H. pylori) infection. However, few studies validated these concepts with high-definition endoscopy without ME. AIM: To access the association between mucosal surface pattern under near focus technology and H. pylori infection status in a western population. METHODS: Cross-sectional study including all patients referred to routine upper endoscopy. Endoscopic exams were performed using standard high definition (S-HD) followed by near focus (NF-HD) examination. Presence of erythema, erosion, atrophy, and nodularity were recorded during S-HD, and surface mucosal pattern was classified using NF-HD in the gastric body. Biopsies were taken for rapid urease test and histology. RESULTS: One hundred and eighty-seven patients were analyzed from August to November 2019. Of those, 47 (25.1%) were H. pylori+, and 42 (22.5%) had a previous H. pylori treatment. In the examination with S-HD, erythema had the best sensitivity for H. pylori detection (80.9%). Exudate (99.3%), nodularity (97.1%), and atrophy (95.7%) demonstrated better specificity values, but with low sensitivity (6.4%-19.1%). On the other hand, the absence of erythema was strongly associated with H. pylori- (negative predictive value = 92%). With NF-HD, 56.2% of patients presented type 1 pattern (regular arrangement of collecting venules, RAC), and only 5.7% of RAC+ patients were H. pylori+. The loss of RAC presented 87.2% sensitivity for H. pylori detection, 70.7% specificity, 50% positive predictive value, and 94.3% negative predictive value, indicating that loss of RAC was suboptimal to confirm H. pylori infection, but when RAC was seen, H. pylori infection was unlikely. CONCLUSION: The presence of RAC at the NF-HD exam and the absence of erythema at S-HD were highly predictive of H. pylori negative status. On the other hand, the loss of RAC had a suboptimal correlation with the presence of H. pylori.
RESUMO
Acute post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is a feared and potentially fatal complication that can be as high as up to 30% in high-risk patients. Pre-examination measures, during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events. Several studies have debated on the subject, however, numerous topics remain controversial, such as the effectiveness of prophylactic medications and the amylase dosage time. This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.

BACKGROUND/AIMS: Argon plasma coagulation (APC) is the most commonly used endoscopic treatment for gastric antral vascular ectasia (GAVE). Endoscopic band ligation (EBL) has emerged as an alternative therapy. Our goal was to evaluate the feasibility, efficacy, and safety of APC and EBL for the treatment of GAVE. This is the first systematic review that included only randomized controlled trials (RCTs) on this topic. METHODS: A comprehensive search was performed using electronic databases to identify RCTs comparing APC and EBL for the treatment of GAVE following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RESULTS: Four RCTs were included, with a total of 204 patients. EBL was related to higher endoscopic eradication rates risk difference [RD], 0.29; 95% confidence interval [CI] [0.14, 0.44]; I2=0%) and less bleeding recurrence than APC (RD, 0.29; 95% CI [0.15, 0.44]; I2=0%). Patients treated with EBL required fewer blood transfusions (mean difference [MD], 1.49; 95% CI [0.28, 2.71]; I2=96%) and hospitalizations (MD, 0.29; 95% CI [0.19, 0.39]; I2=0%). The number of sessions required for the obliteration of lesions was higher with APC. There was no difference in the incidence of adverse events. CONCLUSION: EBL is superior to APC in the treatment of GAVE in terms of endoscopic eradication rates, recurrence of bleeding, and transfusion requirements.
RESUMO
Intragastric balloon (IGB) is a minimally invasive and reversible therapy for weight loss with a good efficacy and safety profile. Introduced in the 1980s, IGBs have significantly evolved in the last couple of decades. They mechanically act by decreasing the volume of the stomach and its reservoir capacity, delaying gastric emptying, and increasing satiety leading to a subsequent weight loss. Despite the low rates of complications and mortality associated with IGBs, adverse events and complications still occur and can range from mild to fatal. This review aims to provide an update on the current scientific evidence in regard to complications and adverse effects of the use of the IGB and its treatment. This is the first comprehensive narrative review in the literature dedicated to this subject.

Pancreatic fluids collections are local complications related to acute or chronic pancreatitis and may require intervention when symptomatic and/or complicated. Within the last decade, endoscopic management of these collections via endoscopic ultrasound-guided transmural drainage has become the gold standard treatment for encapsulated pancreatic collections with high clinical success and lower morbidity compared to traditional surgery and percutaneous drainage. Proper understanding of anatomic landmarks, including assessment of the main pancreatic duct and any associated lesions - such as disruptions and strictures - are key to achieving clinical success, reducing the need for reintervention or recurrence, especially in cases with suspected disconnected pancreatic duct syndrome. Additionally, proper review of imaging and anatomic landmarks, including collection location, are pivotal to determine type and size of pancreatic stenting as well as approach using long-term transmural indwelling plastic stents. Pancreatography to adequately assess the main pancreatic duct may be performed by two methods: Either non-invasively using magnetic resonance cholangiopancreatography or endoscopically via retrograde cholangiopan-creatography. Despite the critical need to understand anatomy via pancrea-tography and assess the main pancreatic duct, a standardized approach or uniform assessment strategy has not been described in the literature. Therefore, the aim of this review was to clarify the role of pancreatography in the endoscopic management of encapsulated pancreatic collections and to propose a new classification system to aid in proper assessment and endoscopic treatment.
