Proposal and Validation of New Diagnostic Criteria for Diagnostic Weights of Endoultrasonographic Findings for Early Chronic Pancreatitis. J Clin Med 2023; 12:5320. [PMID: 37629362 PMCID: PMC10455995 DOI: 10.3390/jcm12165320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 07/30/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
[Background and study aim] A commonly applied method for diagnosing chronic pancreatitis (CP) uses endoscopic ultrasonography (EUS), assigning weights to each EUS diagnostic finding. It is the Rosemont classification (RC). In 2019, to improve EUS diagnostic specificity, Japanese diagnostic criteria for early chronic pancreatitis (ECP) were revised. Nevertheless, the criteria use no weighting of EUS diagnostic findings, as the RC does. This study was undertaken to propose diagnostic criteria that would weight each EUS finding of ECP and that would be more specific than the RC. [Methods] By EUS of the pancreas, 773 patients underwent detailed observation from January 2018 to March 2019 at our institution. An expert finalized all cases when patients were diagnosed. Using data from the medical records, 97 consecutive patients with EUS diagnostic findings of ECP based on the Japanese diagnostic criteria of ECP2009 (JDCECP2009) were selected. The definition under the RC of "Indeterminate for CP" was equivalent to ECP. Each case was diagnosed using (1) JDCECP2009 and (2) the Japanese diagnostic criteria of ECP2019 (JDCECP2019). Moreover, the four diagnostic EUS findings in JDCECP2019 were applied to the RC, weighted (modified-JDCECP2019), and subsequently compared with the earlier diagnostic criteria. As Modified-JDCECP2019, we suggested (3) RC-A-the current four items scored related to the RC, and (4) RC-B-the five items scored by dividing lobularity with and without honeycombing. [Results] Diagnoses produced based on each criterion were normal: ECP = (1) 20:77, (2) 46:51, (3) 52:42, and (4) 60:35. [Conclusions] Modified-JDCECP2019 may provide EUS diagnoses for ECP with higher specificity.

Abstract
The study aimed to demonstrate rapid and effective molecular testing on liquid-based cytology (LBC) samples for EGFR, KRAS and BRAF mutations using the Biocartis Idylla™. Rapid on-site evaluation (ROSE) LBC samples for patients with non-small cell lung carcinoma (NSCLC) or pancreatic ductal adenocarcinoma (PDAC) were tested for EGFR, KRAS and BRAF mutations based on the relevance to tumour subtype. The quantification values (Cq values) and mutation detection status were compared between LBC samples and routine formalin-fixed paraffin-embedded (FFPE) clot samples. ROSE LBC samples (n = 54) showed a higher yield of well-preserved tumour and wild type (WT) DNA, demonstrated by lower quantification cycles, no false positives or false negatives, and a higher sensitivity for low allele frequency mutations when compared with FFPE clot samples. The Biocartis Idylla™ provides highly sensitive, reliable and rapid testing for LBC samples for the detection of EFGR and KRAS mutations. BRAF mutations were not detected in the participant cohort; however, all LBC WT BRAF results correlated with the results from the FFPE clot samples. Access to rapid molecular testing using LBC samples can detect the most frequent driver mutations closer to the time of diagnosis, enabling the selection of the most effective first-line targeted therapy sooner, reducing delays or side effects from suboptimal treatments, patient anxiety and costs to healthcare systems, whilst improving patient outcomes.

Abstract
Background Over the past 40 years, endoscopic ultrasound (EUS) has become a safe and effective tool for both diagnostic and therapeutic applications. A growing number of articles have been published annually. We aimed to explore global scientific outputs and hotspots of EUS published by different countries, organizations, and authors. Methods The global literature regarding EUS during the 1900–2020 period was identified from the Web of Science (WOS) Core database. “Bibliometrix” and software VOSviewer were applied to perform bibliometric analysis. Results The annual growth rate of publications from 1980 to 2020 was around 16% and the number of EUS-related articles had experienced a sudden increase in the last decade. Bhutani MS was the most productive author over the past years, with 94 publications. Hawes RH had the highest number of citations, with 6,034 citations. The United States and institutions from United States dominated the EUS research. Among the journals, GASTROINTESTINAL ENDOSCOPY published the highest number of articles, followed by ENDOSCOPY. The majority of top 10 frequently cited references were cited more than 200 times. Carcinoma, diagnosis, fine-needle-aspiration, cytology, and pancreatitis were the important keywords in co-occurrence analysis of keywords. Recent studies focused more on tissue acquisition, size of the needle, lumen-apposing metal stent, and fine-needle- biopsy. Conclusion Research on EUS has significantly increased in the last decade globally and it will continue to increase. Active collaboration among different authors and countries was observed in the EUS field. Tissue acquisition, size of the needle, apposing metal stent, and fine-needle-biopsy might be the latest research frontiers and should receive more attention.

Endoscopic Ultrasound in the Diagnosis of Pancreatoduodenal Groove Pathology: Report of Three Cases and Brief Review of the Literature. Clin Endosc 2018; 52:196-200. [PMID: 30408946 PMCID: PMC6453847 DOI: 10.5946/ce.2018.097] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Accepted: 08/31/2018] [Indexed: 12/15/2022] Open
Abstract
The pancreatoduodenal groove is a small area where pathologic processes involving the distal bile duct, duodenum, pancreatic head, ampulla of Vater, and retroperitoneum converge. Despite great advances in imaging techniques, a definitive preoperative diagnosis is challenging because of the complex anatomy of this area. Therefore, surgical intervention is frequently required because of the inability to completely exclude malignancy. We report 3 cases of patients with different groove pathologies but similar clinical and imaging presentation, and show the essential role of endoscopic ultrasound (EUS) in making a specific preoperative diagnosis, excluding malignancy in the first case, changing diagnosis in the second case, and confirming malignancy in the third case. EUS was a fundamental tool in this cohort of patients, not only because of its ability to provide superior visualization of a difficult anatomical region, but because of the ability to guide precise, real-time procedures, such as fine-needle aspiration.

Abstract
Upper abdominal pain, icterus and cholestasis are the main symptoms leading to evaluation of the biliary tract. Since the advent of contrast-enhanced ultrasound techniques the accuracy of bile duct imaging has significantly improved. This is also true for computed tomography using isotropic secondary reconstructions as well as magnetic resonance imaging (MRI) including MR cholangiography (MRC), classically and after iv injection of hepatobiliary contrast agent. Diffusion-weighted imaging sequences have a recently proven ability for improving biliary tract imaging. These technical improvements provide the depiction of the non-dilated biliary tract system in diagnostic quality. Therefore, normal variants and congenital disorders of biliary tract anatomy are delineated as well as insights into the postoperative situs and complications related to surgery. Cholelithiasis is the most frequent disease of the gall bladder and biliary tract. Together with related complications, in the majority of cases it is also the reason for bile duct inflammation. Due to the immediate need for treatment special care has to be taken for hydrops of the gall bladder.

Abstract
PURPOSE To investigate (1) diagnostic performance of transabdominal color doppler ultrasound (US) and endoscopic ultrasound (EUS) for detection and sub-classification of common bile duct varices (CBDV) in patients with portal vein thrombosis (PVT), and (2) clinical significance and natural history of CBDV subtypes. PATIENTS AND METHODS During a 4-year period, 56 patients with PVT underwent US and EUS for the presence and subtypes of CBDV. Natural history was analyzed for patients who attended control visits. RESULTS CBDV were diagnosed in 57 and 59 % of patients with US and EUS, respectively. In 19 % of patients, EUS revealed different CBDV subtypes than previously seen by US. The most common were paracholedochal (PCV), while the least common were epicholedochal (ECV) and Submucosal varices (SMV). Nine patients had obstructive jaundice and underwent ERCP which was complicated by hemobilia in two patients with SMV. Among eight patients who underwent control EUS (median follow-up 60 months), the form of CBDV remained unchanged. Two patients bled from esophageal varices, both with ECV. CONCLUSION While abdominal US and EUS are equally sensitive for detection of CBDV, EUS allows more precise determination of CBDV subtype. Patients with SMV might be at increased risk of bleeding upon ERCP.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound has become an invaluable tool in the investigation of patients with suspected pancreatobiliary disease. We set out to determine whether a "direct-to-test" endoscopic ultrasound procedure could be offered to selected patients with suspected choledocholithiasis. METHODS AND RESULTS We included patients referred to our general gastroenterology service with clinical history, symptomatology and/or laboratory results compatible with choledocholithiais. Almost all patients had already had a transabdominal ultrasound performed at the request of their general practitioner. All patients underwent direct-to-test day-case endoscopic ultrasound under conscious sedation. Procedures were performed by a single practitioner using an oblique-viewing radial echoendoscope. The diagnostic yield and frequencies of discharge, onward referral and follow-up were determined. Overall diagnostic yield of direct-to-test endoscopic ultrasound was 61%. The most common diagnoses were cholelithiasis (18%) and choledocholithiasis (11%); one periampullary cancer was also detected. A definitive outcome (discharge or referral for a therapeutic procedure) occurred in 14 of 28 patients (50%). The remaining 14 patients underwent further out-patient evaluation. Eventual diagnoses in this group included autoimmune hepatitis, primary biliary cirrhosis and drug-induced hepatitis. CONCLUSIONS For patients with suspected biliary disease, direct-to-test endoscopic ultrasound has a high diagnostic yield, and may be an appropriate mode of investigation.

Abstract
Since its advent in 1980, the scope of endoscopic ultrasound (EUS) has grown to include a wide range of indications, and it is now being incorporated as an integral part of everyday practice in the field of gastroenterology. Its use is extending from an adjuvant imaging aid to utilization as a therapeutic tool for various gastrointestinal disorders. EUS was first used to visualize remote organs, such as the pancreas and abdominal lymph nodes. When fine needle aspiration was introduced, the indications for EUS expanded to include tissue sampling for diagnostic purposes. At the same time, the needle can be used to convey a potential therapy to the internal organs, allowing access to remote sites. In this review, we aim to highlight the expanding spectrum of EUS indications and uses in the field of gastroenterology.
