Abstract
Background and aims Endoscopic ultrasonography (EUS) is commonly utilized in the diagnosis of pancreatic tumors, although as this modality relies primarily on the practitioner's visual judgment, it is prone to result in a missed diagnosis or misdiagnosis due to inexperience, fatigue, or distraction. Deep learning (DL) techniques, which can be used to automatically extract detailed imaging features from images, have been increasingly beneficial in the field of medical image-based assisted diagnosis. The present systematic review included a meta-analysis aimed at evaluating the accuracy of DL-assisted EUS for the diagnosis of pancreatic tumors diagnosis. Methods We performed a comprehensive search for all studies relevant to EUS and DL in the following four databases, from their inception through February 2023: PubMed, Embase, Web of Science, and the Cochrane Library. Target studies were strictly screened based on specific inclusion and exclusion criteria, after which we performed a meta-analysis using Stata 16.0 to assess the diagnostic ability of DL and compare it with that of EUS practitioners. Any sources of heterogeneity were explored using subgroup and meta-regression analyses. Results A total of 10 studies, involving 3,529 patients and 34,773 training images, were included in the present meta-analysis. The pooled sensitivity was 93% (95% confidence interval [CI], 87-96%), the pooled specificity was 95% (95% CI, 89-98%), and the area under the summary receiver operating characteristic curve (AUC) was 0.98 (95% CI, 0.96-0.99). Conclusion DL-assisted EUS has a high accuracy and clinical applicability for diagnosing pancreatic tumors.

Abstract
BACKGROUND Endoscopic ultrasonography is a safe and accurate modality for evaluating and managing hepatobiliary and gastrointestinal conditions (malignant and nonmalignant); its use is increasing. The aim of this study was to describe regional trends in the use of endoscopic ultrasonography in Ontario. METHODS We conducted a population-based retrospective cohort study using health administrative databases. We identified all patients who underwent an endoscopic ultrasound procedure in Ontario from 2003 to 2011 using physician billing data. Patient, physician and institution characteristics were examined. The primary outcome was use of endoscopic ultrasonography. RESULTS We identified 9076 endoscopic ultrasound procedures performed in 8001 patients (3858 women [48.2%]; median patient age at first procedure 59 years). A total of 3066 procedures (33.8%) involved fine-needle aspiration. Use of endoscopic ultrasonography increased 17-fold over the study period. In 2011, people living in the health region with the highest rate of use of endoscopic ultrasonography were more than 4 times more likely to undergo the procedure than people living in the health region with the lowest rate of use (standardized rate 61.6 v. 12.9 per 100 000). About 7 in 10 endoscopic ultrasound procedures were performed in an academic institution or regional cancer centre. All 17 endoscopists performing endoscopic ultrasonography during the study period practised in urban areas. INTERPRETATION Although the use of endoscopic ultrasonography increased over time in Ontario, there were marked regional differences in use. Provincial needs- and evidence-based initiatives may be needed to narrow the regional gaps in provision of endoscopic ultrasound services in the province.

Diagnostic and Therapeutic Roles of Endoscopic Ultrasound in Pediatric Pancreaticobiliary Disorders. J Pediatr Gastroenterol Nutr 2015; 61:238-47. [PMID: 25564818 DOI: 10.1097/mpg.0000000000000692] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
OBJECTIVES The diagnostic role of endoscopic ultrasound (EUS) in children has only recently been demonstrated, and that also to a lesser extent than in adults. Data on the technique's therapeutic indications remain scarce. We therefore sought to evaluate diagnostic and interventional EUS indications, safety, and impact in children with pancreaticobiliary disorders. METHODS We retrospectively reviewed our single pediatric center records, covering a 14-year period. RESULTS From January 2000 to January 2014, 52 EUS procedures were performed in 48 children (mean age: 12 years; range: 2-17 years) with pancreaticobiliary disorders for the following indications: suspected biliary obstruction (n = 20/52), acute/chronic pancreatitis (n = 20), pancreatic mass (n = 3), pancreatic trauma (n = 7), and ampullary adenoma (n = 2). EUS was found to have a positive impact in 51 of 52 procedures, enabling us to avoid endoscopic retrograde cholangiopancreatography (ERCP) (n = 13 biliary; n = 6 pancreatic), focusing instead on endotherapy (n = 7 biliary; n = 14 pancreatic) or reorienting therapy toward surgery (n = 7). EUS-guided fine-needle aspiration was carried out on 12 patients for pancreatic tumor (n = 4), pancreatic cyst fluid analysis (n = 4), autoimmune pancreatitis (n = 2), and suspicion of biliary tumor (n = 2). A total of 13 therapeutic EUS procedures (11 children) were conducted, including 9 combined EUS-ERCP procedures (7 children, mean age: 8 years, range: 4-11 years), 3 EUS-guided pseudocyst drainage (2 children), and 1 EUS-guided transgastric biliary drainage. CONCLUSIONS Our study reports on a large pediatric EUS series for diagnostic and therapeutic pancreaticobiliary disorders, demonstrating the impact of diagnostic EUS and affording insights into novel EUS and combined EUS-ERCP therapeutic applications. We suggest considering EUS as a diagnostic and therapeutic tool in the management of pediatric pancreaticobiliary diseases.
