[PMID: 37490244 DOI: 10.1007/s10396-023-01342-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 06/15/2023] [Indexed: 07/26/2023]
Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the first-choice procedure for obtaining pathological tissue samples from gastrointestinal (GI) subepithelial lesions (SELs). However, its diagnostic accuracy is lower than that for pancreatic masses owing to puncture difficulty and the need for immunostaining for definitive diagnosis. The advent of fine-needle biopsy needles, which have become well known in recent years, improves the diagnostic accuracy of EUS-FNA for GI SELs. The forward-viewing echoendoscope and rapid on-site evaluation (ROSE) have also helped to improve diagnostic accuracy. Furthermore, in facilities where ROSE is not available, endosonographers perform a macroscopic on-site evaluation. With these procedural innovations, EUS-FNA is now performed aggressively even for SELs smaller than 20 mm. The incidence of procedure-related adverse events such as bleeding and infection is low, and thus, EUS-FNA can be safely performed to diagnose SELs.

Macroscopic on‑site quality evaluation of biopsy specimens to improve the diagnostic accuracy of endoscopic ultrasound‑guided fine needle aspiration using a 22‑gauge needle for solid lesions: A single‑center retrospective study. Exp Ther Med 2023; 26:338. [PMID: 37383379 PMCID: PMC10294598 DOI: 10.3892/etm.2023.12037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 05/03/2023] [Indexed: 06/30/2023] Open
Abstract
The present study aimed to evaluate the clinical value of macroscopic on-site evaluation (MOSE) of solid masses by endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) using a standard 22-gauge needle and to explore the cut-off length of macroscopic visible core (MVC) required to obtain an accurate histopathological diagnosis. In total, 119 patients who satisfied the inclusion and exclusion criteria and underwent EUS-FNA were divided into conventional FNA and FNA combined with MOSE groups. In the MOSE group, the presence of MVC was examined and its total length measured, after which the pathological results of FNA were compared with the final diagnosis. The diagnostic sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of FNA in the two groups were calculated and the effect of MOSE on the FNA result was analyzed. The MOSE group had a higher diagnostic sensitivity (75.0% vs. 89.8%; P=0.038) and accuracy (74.5% vs. 90.6%; P=0.026). MVC was observed in 98.4% (63/64) of patients in the MOSE group. The median length of MVC was 15 mm. The optimal cut-off length of MVC for obtaining an accurate histological diagnosis was 13 mm, with a sensitivity of 90.2%. No statistically significant significance was observed in the specificity, PPV and NPV between the groups. Thus, MOSE helps to improve the diagnostic ability of FNA for solid masses and may be a useful alternative to assess the adequacy of puncture specimens in units where rapid on-site evaluation cannot be performed.

Application of artificial intelligence to digital-rapid on-site cytopathology evaluation during endoscopic ultrasound-guided fine needle aspiration: A proof-of-concept study. J Gastroenterol Hepatol 2023; 38:883-887. [PMID: 36409289 DOI: 10.1111/jgh.16073] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 11/06/2022] [Accepted: 11/16/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND During endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), cytopathology with rapid on-site evaluation (ROSE) can improve diagnostic yield and accuracy. However, ROSE is unavailable in most Asian and European institutions because of the shortage of cytopathologists. Therefore, developing computer-assisted diagnostic tools to replace manual ROSE is crucial. Herein, we reported the validation of an artificial intelligence (AI)-based model (ROSE-AI model) to substitute manual ROSE during EUS-FNA. METHODS A total of 467 digitized images from Diff-Quik (D&F)-stained EUS-FNA slides were divided into training (3642 tiles from 367 images) and internal validation (916 tiles from 100 images) datasets. The ROSE-AI model was trained and validated using training and internal validation datasets, respectively. The specificity was emphasized while developing the model. Then, we evaluated the AI model on a 693-image external dataset. We assessed the performance of the AI model to detect cancer cells (CCs) regarding the accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS The ROSE-AI model achieved an accuracy of 83.4% in the internal validation dataset and 88.7% in the external test dataset. The sensitivity and PPV were 79.1% and 71.7% in internal validation dataset and 78.0% and 60.7% in external test dataset, respectively. CONCLUSION We provided a proof of concept that AI can be used to replace manual ROSE during EUS-FNA. The ROSE-AI model can address the shortage of cytopathologists and make ROSE available in more institutes.

Diagnostic value of endoscopic ultrasound-guided fine needle aspiration with rapid on-site evaluation performed by endoscopists in solid pancreatic lesions: A prospective, randomized controlled trial. J Gastroenterol Hepatol 2022; 37:1975-1982. [PMID: 35614028 DOI: 10.1111/jgh.15897] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 03/18/2022] [Accepted: 05/14/2022] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIM Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the most established diagnostic method for pancreatic tissue. Rapid on-site evaluation by a trained endoscopist (self-ROSE) can improve the diagnostic accuracy. This research is aimed to analyze the application value of self-ROSE for EUS-FNA in solid pancreatic lesions. METHODS A total of 194 consecutive patients with solid pancreatic lesions in Nanjing Drum Tower Hospital were randomized in a 1:1 ratio to EUS-FNA with or without self-ROSE in this single-center randomized controlled trial. Before initiating self-ROSE, the endoscopist underwent training for pancreatic cytologic sample adequacy assessment and cytopathological diagnosis of EUS-FNA in pathology department for 1 month. Some parts of the slides of EUS-FNA were air dried, stained on-site with BASO Liu's reagent, and on-site evaluated in self-ROSE group. Between the two groups, the diagnostic performance of EUS-FNA was analyzed, including sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, with a comparison of the number of needle passes and the complication rates. RESULTS The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were 94.8%, 94.4%, 100%, 100%, and 58.3% in the self-ROSE group, respectively, and 70.1%, 65.1%, 100%, 100%, and 32.6% in the non-self-ROSE group. The diagnostic accuracy (P < 0.001) and sensitivity (P < 0.001) were both significantly increased during EUS-FNA in the self-ROSE group compared to the non-self-ROSE group. The rate of cytologic sample adequacy was 100% in self-ROSE group and 80.4% in non-self-ROSE group. The number of passes were 3.38 ± 1.00 in self-ROSE group and 3.22 ± 0.89 in non-self-ROSE group (P = 0.228). No complications were found in both. There was acceptable consistency between endoscopist and pathologist in the cytopathological diagnosis (kappa = 0.666, P < 0.05) and in the sample adequacy rate (kappa = 1.000, P < 0.001). CONCLUSION Our results demonstrated that self-ROSE is valuable for EUS-FNA in the diagnosis of solid pancreatic lesions and is an important choice to routinely increase the accuracy of EUS-FNA in centers without ROSE assessment.

Abstract
Background We aimed to develop a deep learning-based segmentation system for rapid on-site cytopathology evaluation (ROSE) to improve the diagnostic efficiency of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy. Methods A retrospective, multicenter, diagnostic study was conducted using 5345 cytopathological slide images from 194 patients who underwent EUS-FNA. These patients were from Nanjing Drum Tower Hospital (109 patients), Wuxi People's Hospital (30 patients), Wuxi Second People's Hospital (25 patients), and The Second Affiliated Hospital of Soochow University (30 patients). A deep convolutional neural network (DCNN) system was developed to segment cell clusters and identify cancer cell clusters with cytopathological slide images. Internal testing, external testing, subgroup analysis, and human–machine competition were used to evaluate the performance of the system. Findings The DCNN system segmented stained cells from the background in cytopathological slides with an F1-score of 0·929 and 0·899–0·938 in internal and external testing, respectively. For cancer identification, the DCNN system identified images containing cancer clusters with AUCs of 0·958 and 0·948–0·976 in internal and external testing, respectively. The generalizable and robust performance of the DCNN system was validated in sensitivity analysis (AUC > 0·900) and was superior to that of trained endoscopists and comparable to cytopathologists on our testing datasets. Interpretation The DCNN system is feasible and robust for identifying sample adequacy and pancreatic cancer cell clusters. Prospective studies are warranted to evaluate the clinical significance of the system.

Abstract
Objectives: This study aimed to examine the effects of a training program combining formal cytological curriculum and practical assessments on endosonographers and to determine how many operations were needed for training through learning curves. Methods: A formal cytological curriculum was implemented in November 2019 for four endosonographers. The competency of endosonographers before and after the curriculum was judged by quantitative scores. From December 2019 to October 2020, trainees independently examined the adequacy and atypia grade of pancreatic specimens acquired by EUS-guided-fine-needle biopsy based on specific atypical grading criteria. The accuracy of the adequacy and atypia assessment of each trainee was calculated, and learning curves were drawn to evaluate the improvement. Results: The median posttraining score improved by 87% from 49 to 91.5 out of 100. Ninety patients were enrolled in the practical assessments. The accuracy for specimen adequacy and atypia assessment of each trainee was 91.7%, 92.8%, 91.0%, and 89.3% and 80.0%, 82.1%, 81.0%, and 78.9%. The learning curves of each trainee showed a steady and significant improvement, and ninety cases were sufficient for satisfactory adequacy assessment. Conclusions: Basic knowledge of on-site cytopathologic evaluation can be gained through standardized and systematic training. Practical assessments showed that, at the completion of ninety cases, trained endosonographers reached a satisfactory level of recognizing specimen adequacy, but continue practice was needed for atypia assessment.

Optimal Techniques for EUS-Guided Fine-Needle Aspiration of Pancreatic Solid Masses at Facilities without On-Site Cytopathology: Results from Two Prospective Randomised Trials. J Clin Med 2021; 10:jcm10204662. [PMID: 34682785 PMCID: PMC8540534 DOI: 10.3390/jcm10204662] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 09/17/2021] [Accepted: 10/08/2021] [Indexed: 12/26/2022] Open
Abstract
Background: EUS-guided fine-needle aspiration (EUS-FNA) has emerged as the primary modality for the cytologic diagnosis of pancreatic solid masses. The aim of this study is to determine whether technical factors including suction (S), non-suction (NS), capillary sampling with stylet slow-pull (CSSS), and the number of needle actuations (to-and-fro needle movements) may affect the accuracy of EUS-FNA for pancreatic solid masses at facilities without on-site cytopathology. Methods: The diagnostic yield of malignancy, blood contamination and cellularity at each sample acquired from EUS-FNA with or without S and different numbers of actuation (10, 15 and 20) were measured (study I). The optimal actuation number was determined and a head-to-head comparison trial between S and CSSS was performed (study II). Results: In study I, significant blood contamination was seen using S with 20 compared with 15 actuations (p = 0.002). Diagnostic yield of malignancy was not significantly different between 10, 15, and 20 actuations with S, whereas it was statistically higher for 15 actuations compared with 10 actuations with NS (p = 0.001). In study II, no difference was noted in diagnostic yield with 15 actuations between S and CSSS (88% vs. 90%, p = 0.74). Conclusions: Increasing actuation in NS resulted in a better diagnostic yield for EUS-FNA without significant blood contamination, whereas increasing actuation in S did not change the diagnostic yield of EUS-FNA while causing significant blood contamination. With 15 actuations, the diagnostic yield was comparable between S and CSSS.

Abstract
OBJECTIVES Rapid on-site evaluation (ROSE) by cytopathologists during endoscopic ultrasound-fine-needle aspiration (EUS-FNA) of solid pancreatic lesions (SPLs) improves adequacy and diagnostic accuracy while reducing the number of needle passes. We evaluated the usefulness of ROSE performed by the endosonographer. METHODS Patients with an SPL were randomly assigned to EUS-FNA with ROSE or non-ROSE. Procedure duration, number of needle passes, specimen adequacy, and adverse event rates were compared. RESULTS Sixty-five patients were enrolled (33 in the ROSE vs 32 in the non-ROSE group). Both groups were similar in terms of age, sex, size, and location of the lesion. Specimen adequacy rates were high and similar between groups. Mean (standard deviation) procedure duration was shorter in the ROSE versus non-ROSE group (30.0 [11.3] vs 37.0 [7.2] minutes, P < 0.005), as well as the mean (standard deviation) number of needle passes (2.6 [0.8] vs 3.5 [0.8], P < 0.005). Accuracy parameters as sensitivity and accuracy of ROSE by the endosonographer for malignancy were 93% and 88%, respectively. CONCLUSIONS After specific training, the endosonographer can accurately evaluate samples during EUS-FNA of SPL, allowing for a shorter procedure duration and a lower number of needle passes.

Abstract
BACKGROUND In the absence of rapid on-side pathological evaluation, endoscopy staff generally "smears" endoscopic ultrasound guided fine needle aspiration (EUS-FNA) specimens on a glass slide. As this technique is vulnerable to preparation artifacts, we assessed if its quality could be improved through a smear-preparation-training for endoscopy staff. METHODS In this prospective pilot study, 10 endosonographers and 12 endoscopy nurses from seven regional EUS-centers in the Netherlands were invited to participate in a EUS-FNA smear-preparation-training. Subsequently, post training slides derived from solid pancreatic lesions were compared to pre-training "control" slides. Primary outcome was to assess if the training positively affects smear quality and, consequently, diagnostic accuracy of EUS-FNA of solid pancreatic lesions. RESULTS Participants collected and prepared 71 cases, mostly pancreatic head lesions (48%). Sixty-eight controls were selected from the pretraining period. The presence of artifacts was comparable for smears performed before and after training (76% vs 82%, P = .36). Likewise, smear cellularity (≥50% target cells) before and after training did not differ (44% (30/68) vs 49% (35/71), P = .48). Similar, no difference in diagnostic accuracy for malignancy was detected (P = .10). CONCLUSION In this pilot EUS-FNA smear-preparation-training for endoscopy personnel, smear quality and diagnostic accuracy were not improved after the training. Based on these results, we plan to further study other training programs and possibilities.

Abstract
BACKGROUND The use of macroscopic on-site evaluation (MOSE) to estimate the adequacy of a specimen for histological diagnosis during endoscopic ultrasound (EUS)-guided fine-needle tissue acquisition (FNTA) has recently been advocated. This study aimed to evaluate the diagnostic yield of MOSE compared with conventional EUS-FNTA without rapid on-site evaluation (ROSE). METHODS This was an international, multicenter, prospective, randomized controlled study. After providing informed consent, consecutive adult patients referred for EUS-FNTA for solid lesions larger than 2 cm were randomized to a MOSE arm or to a conventional arm without ROSE. A designated cytopathologist from each center performed all cytopathological examinations for that center and was blinded to the randomization results. The primary outcome measure was the diagnostic yield, and the secondary outcomes included sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy, and the rate of procedure-related complications. RESULTS 244 patients (122 conventional, 122 MOSE) were enrolled during the study period. No significant differences between the two arms were found in procedure time or rate of procedure-related adverse events. The diagnostic yield for the MOSE technique (92.6 %) was similar to that for the conventional technique (89.3 %; P = 0.37), with significantly fewer passes made (median: conventional 3, MOSE 2; P < 0.001). CONCLUSIONS EUS-FNTA with the MOSE technique provided a similar diagnostic yield to conventional EUS-FNTA technique in the absence of ROSE but with fewer passes. This technique can be used when ROSE is not available.

Abstract
For a definitive diagnosis of fine-needle aspiration (FNA)/biopsy, one of the reliable techniques to determine the adequacy and accuracy rapid on-site evaluation (ROSE) of cytological samples is preferable. Because of the lack of trained pathologists, alternatives have to be explored. This study is primarily conducted to determine the diagnostic sensitivity and specificity of full-field optical coherence tomography (FF-OCT) and secondarily to evaluate the possibility of FF-OCT differentiating different types of pancreatic diseases. The diagnostic coherence of FF-OCT by a trained assistant (endoscopist) and trained pathologist is also compared. This is a single-center, prospective, observation trial. Eighty patients would be enrolled in the study. The tissue samples acquired by endoscopic ultrasound fine-needle biopsy (EUS-FNB) would be imaged by the FF-OCT system, interpreted by a trained endoscopist and a pathologist. The results of the image interpretation would be verified with histological findings. This study determines the diagnostic capability of FF-OCT as a ROSE technique while performing EUS-FNB, and whether endoscopists can implement the assessment.

Abstract
Background/Aims To compare the diagnostic yield of 20-gauge forward-bevel core biopsy needle (CBN) and 22-gauge needle for endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) of solid pancreatic masses. Methods The use of 20-gauge CBN was prospectively evaluated for 50 patients who underwent EUS-FNA from June 2016 to December 2016. Data were compared with those obtained by a retrospective study of 50 consecutive patients who underwent EUS-FNA using standard 22-gauge needles between December 2016 and April 2017. At least two punctures were performed for each patient; the sample from the first pass was used for cytology with or without histology and that from the second pass was used for histology. Sample quantity was evaluated using the sample obtained from the second pass. Results There was no significant difference in the diagnostic accuracy rate between the first and second passes (20-gauge CBN: 96% [48/50]; standard 22-gauge needle: 88% [44/50]). Samples >10× power fields in length were obtained from 90% (43/48) and 60% (30/50) of patients using the 20-gauge CBN and standard 22-gauge needle, respectively (p=0.01). Technical failure occurred for two patients with the 20-gauge CBN. Conclusions Diagnostic accuracy of the 20-gauge CBN was comparable to that of the 22-gauge needle. However, two passes with the 20-gauge CBN yielded a correct diagnosis for 100% of patients when technically feasible. Moreover, the 20-gauge CBN yielded core tissue for 90% patients, which was a performance superior to that of the 22-gauge needle.

Abstract
BACKGROUND AND AIMS Although rapid on-site cytologic evaluation (ROSE) during EUS-guided FNA biopsy (EUS-FNAB) sampling may improve accuracy of pathologic analyses, cytopathologists are not widely available. We calculated the cutoff lengths required for accurate pathologic diagnoses from stereomicroscopically visible white cores (SVWCs) sampled using 22-gauge needles. METHODS Overall, 118 patients with mediastinal or upper abdominal solid masses requiring pathologic diagnoses were included. EUS-FNAB sampling was performed using 22-gauge needles. SVWCs were isolated and measured using stereomicroscopy, and the utility of calculated cutoff lengths in diagnosis was investigated. RESULTS The procedure success and SVWC sampling rates were both 100%, and the median SVWC length was 10 mm. Pathologic examination identified 75, 31, and 12 patients with pancreatic neoplasms (PNs), subepithelial lesions (SELs), and other lesions, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for diagnosing malignancy using EUS-FNAB sampling were 93.1%, 100%, 100%, 69.6%, and 94%, respectively. The final diagnostic accuracy in the entire cohort, PNs, and SELs was 92.4%, 90.7%, and 93.5%, respectively. Receiver operating characteristic curves demonstrated the overall SVWC cutoff length to be 11 mm (11 mm for PNs, 3.5 mm for SELs). The overall sensitivity according to SVWC cutoff length was 91.4% (87.6% for PNs, 98.8% for SELs). Compared with cutoff length, multivariate analysis confirmed SVWC length to be a stronger independent factor for tissue diagnosis in both groups. CONCLUSIONS Diagnosis improved significantly with SVWC cutoff lengths ≥11 mm. This may be a useful index for endoscopists, particularly where ROSE is unavailable.

Abstract
Background and study aims Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) represents a standard method for tissue acquisition of lesions adjacent to the gastrointestinal wall. Needles of 19 gauge acquire more tissue than needles with a smaller diameter, but are often unable to penetrate solid, rigid masses. In this study we evaluated a novel prototype that links forward movement of the needle to rotation of the needle tip. Materials and methods Two needle-models that generate either a regular axial movement or a combination of axial movement with rotation of the needle tip were compared ex vivo for measurement of pressure needed to penetrate artificial tissue. Furthermore, a standard 19-gauge EUS-FNB needle was compared to a modified model ("Twist Needle") in an ex vivo model to measure the amount of tissue obtained. Results Pressure measurements using the rotating needle revealed that significantly less pressure is needed for penetration compared to the regular axial movement (mean ± SEM; 3.7 ± 0.3 N vs. 5.5 ± 0.3 N). Using the modified 19-gauge "Twist Needle" did not diminish tissue acquisition measured by surface amount compared to a standard needle (37 ± 5 mm² vs. 35 ± 6 mm²). Conclusion The method of rotation of an EUS-FNB needle tip upon forward movement requires less pressure for penetration but does not diminish tissue acquisition. Hence, the concept of our "Twist Needle" may potentially reduce some of the current limitations of standard EUS-FNB.

Abstract
Background and study aims Telecytopathology (TCP) may allow proper and timely evaluation of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) specimens. The aim of this study was to evaluate the feasibility of TC through a multiplatform instant messenger smartphone application to evaluate specimens of EUS-FNA of pancreatic solid lesions. Patients and methods Twenty-three patients (14 male/9 female; median age: 56 yr.; age range: 33 - 86) with a solid pancreatic lesion were included. Exclusion criteria were as follows: age < 18 yr and predominantly cystic lesions. During each EUS-FNA, after each pass, the aspirated material was spread over a glass slide and was stained by the endoscopist. The glass slide was then reviewed on a microscope with a smartphone fitted in, and the most representative fields were captured and sent to the cytopathologist using WhatsApp Messenger. Results In initial evaluation using TCP rapid on-site evaluation (ROSE), adequate cellularity of the glass slide was detected in 16 of 23 patients (69.6 %). An initial diagnosis of malignancy (positive or suspicious) was possible in 14 of 23 patients (60.8 %). Conclusion The current study demonstrated the feasibility of a low-cost, Internet-based, telecytopathology system using WhatsApp Messenger to provide ROSE of EUS-FNA slides in patients with solid pancreatic lesions.

Abstract
Background/Aims We applied a back light system (BLS) with a magnifying glass to improve the ability to assess the adequacy of specimen sampling using endosonography. We conducted this study to evaluate the efficacy of the BLS in sampling of specimens by endoscopic ultrasound-guided fine needle aspiration of solid pancreatic masses.
Methods This was a prospective, randomized, crossover, single-center clinical trial. An endosonographer evaluated adequacy on gross visual inspection and identified whitish specimen sampling sites with and without the BLS according to a randomization sequence in the first and second passes with a 25-G needle. On cytological evaluation, the presence of well-defined pancreatic ductal epithelium was evaluated by a cytopathologist who was blinded to any clinical information.
Results A total of 80 consecutive patients were eligible during the study period. Adequacy was observed for 52 specimens (65%) with the BLS and 54 (68%) without the BLS (p=0.88). In assessment of specimen adequacy on gross examination, only fair agreement was observed both with and without BLS (kappa score 0.40 and 0.29, respectively).
Conclusions The BLS did not influence the ability to identify specimen sampling sites or reliable assessment of specimen site adequacy using gross visual inspection.

Abstract
Liquid-based cytology (LBC) is a thin-layer slide preparation procedure that was developed to overcome the cell crowding and contamination associated with smear cytology (SC). The present study compared diagnostic efficacy between SC alone and SC combined with LBC (SLBC) using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) samples of pancreatic lesions.We retrospectively analyzed data derived from 311 consecutive patients. Specimens obtained via EUS-FNA from 179 patients between December 2011 and May 2016 were analyzed by SC, and those obtained from 132 patients between June 2016 and October 2017 were analyzed by SLBC. The 2 groups were compared in terms of adequate sample rate, diagnostic accuracy, sensitivity, and specificity using propensity score matching.SC and SLBC were compared using propensity score-matching in 204 patients (n = 102 per group). The adequate sample rate did not differ significantly between SLBC (100%) and SC (99.0%, P = 1). Diagnostic sensitivity, negative predictive value and accuracy were better for SLBC than for SC in terms of cytological (93.2% vs 67.4%, 68.4% vs 23.1%, and 94.1% vs 69.6%, P < .01 each, respectively) and cytohistological (95.5% vs 81.5%, 76.5% vs 34.6%, and 96.1% vs 82.4%, P < .01, P = .02, and P < .01, respectively) analyses.SLBC improves the diagnostic efficacy of EUS-FNA for pancreatic lesions compared to LBC.

A Trained Pulmonologist Can Reliably Assess Endosonography-Derived Lymph Node Samples during Rapid On-Site Evaluation. Respiration 2019; 97:540-547. [PMID: 30982053 DOI: 10.1159/000496549] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Accepted: 12/31/2018] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The widespread use of rapid on-site evaluation is hampered by constraints related to time and resources, inadequate reimbursement, and evidence from randomized trials that show a lack of increase in diagnostic yield and specimen adequacy associated with its usage. OBJECTIVE We aimed to verify whether a pulmonologist can assess endosonography-derived lymph node samples after a comprehensive and reproducible training provided by a specialist pathologist. METHODS Prospective, observational trial structured in three phases. In the first (training) phase, a pathologist critically evaluated the smears from 150 archival endosonography cases with a pulmonologist. In the second (test) phase, the pulmonologist was asked to assess 50 archival endosonography-derived samples. In the last (real-life) phase, the pulmonologist classified the samples from 200 patients during the endosonography. The overall agreement between pulmonologist and pathologist (gold standard), assessed through κ-statistics, was the primary outcome. The agreement for the identification of specific cytological categories was the secondary outcome. RESULTS The overallagreement between pulmonologist and pathologist was 84% (κ0.765, 95% CI 0.732-0.826) in the test phase and 89.7% (κ 0.844, 95% CI 0.799-0.881) in the real-life phase. The agreement for specific cytological categories was 92.7% (95% CI 0.824-0.980) for inadequate samples, 90.3% (95% CI 84.5-94.5%) for reactive lymphadenopathies, 90.5% (95% CI 0.845-0.946) for malignancy, and 73% (95% CI 0.515-0.897) for granulomatous samples. CONCLUSIONS A trained pulmonologist can reliably assess adequacy and malignancy for endosonography-derived samples, which could be useful in institutions where a cytopathologist/cytotechnician is not available regularly.

Abstract
BACKGROUND AND AIM Few studies compared endoscopic ultrasound (EUS)-guided fine needle aspiration (EUS-FNA) with endoscopic retrograde cholangiopancreatography (ERCP)-based tissue sampling in terms of diagnostic accuracy in suspected malignant biliary obstruction. We evaluated and compared the diagnostic performance of EUS-FNA and ERCP-based tissue sampling. METHODS This multicenter study included 263 patients with suspected malignant biliary obstruction who underwent same-session EUS and ERCP between 2012 and 2016. RESULTS Malignancies were confirmed in 239 patients (90.9%) and benign in 24 patients (9.1%). Overall diagnostic sensitivity and accuracy were 73.6% and 76.1% for EUS-FNA, 56.5% and 60.5% for ERCP, and 85.8% and 87.1% for EUS/ERCP combination. EUS-FNA showed higher overall performances compared with ERCP (P < 0.001), whereas EUS/ERCP combination was superior to EUS-FNA alone (P-value < 0.001). EUS-FNA showed higher sensitivity and accuracy compared with ERCP for pancreatic masses (n = 187, both P-values < 0.001) but not for biliary lesions (n = 76, both P-values = 0.847). Sensitivity and accuracy of EUS/ERCP combination were superior to those of EUS-FNA for both pancreatic and biliary lesions (both P-values < 0.001). For patients with large mass (≥ 4 cm), there was no significant differences between ERCP/EUS combination and EUS-FNA (P-value = 0.31). CONCLUSIONS Same-session EUS-FNA and ERCP combination was superior to EUS-FNA for both pancreatic masses and biliary lesions. Same-session EUS/ERCP combination can be considered a proper diagnostic method for suspected malignant biliary obstruction regardless of the origin of lesions. On the other hand, EUS-FNA alone was sufficient for diagnosis compared with EUS/ERCP combination in cases with large mass. Strategic diagnostic approach, according to clinical features of individual patient, is required.

Abstract
Background and Objectives EUS-guided tissue acquisition with rapid on-site cytologic evaluation (ROSE) has been used to increase the diagnostic yield. However, ROSE is not available in many centers. To date, only a few studies have assessed the adequacy of histologic cores in macroscopic on-site evaluation (MOSE) during EUS-guided fine-needle biopsy (EUS-FNB). Blood contamination of histologic core specimens lowers the sample quality and the diagnostic yield. Therefore, we evaluated the efficacy of MOSE using filter paper to increase the adequacy of histologic core specimens while minimizing blood contamination. Materials and Methods Seventy-nine consecutive patients with an intraabdominal mass underwent EUS-FNB between March 2017 and October 2018. Histologic specimens obtained using EUS-FNB were expelled onto filter paper, and the histologic procurement rate on MOSE was evaluated. Results EUS-FNB using a 20-gauge Procore needle or a 22-gauge Acquire needle was successful in all patients. The mean number of needle passes was 2.8 ss0.8. Visible histologic cores were observed in 94.9% (75/79) of the patients. Blood-contaminated specimens with scanty histologic cores were obtained in 5.1% (4/79) of the patients. On microscopic examination, 92.4% (73/79) of the histologic samples were graded as optimal. The diagnostic accuracy, sensitivity, and specificity were 94.5%, 94.3%, and 100%, respectively. Mild postprocedural adverse events occurred in 2 patients (2.5%: n = 1, transient fever; n = 1, acute pancreatitis). Conclusions MOSE using filter paper provided adequate histologic samples while minimizing blood contamination. MOSE can also increase the diagnostic accuracy when ROSE is not available.

Abstract
OBJECTIVES Few studies are available on high negative pressure (HNP) during endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). This study compared the diagnostic yield between HNP and normal negative pressure (NNP) during EUS-FNA for solid pancreatic masses. METHODS Consecutive patients with pancreatic masses who underwent EUS-FNA using a 22-G needle with either HNP or NNP for both the first and second passes were retrospectively examined for diagnostic yield. Rapid on-site evaluation (ROSE) was unavailable at our center. The main outcome measures were the number of passes, diagnostic accuracy and quantity of histological samples. RESULTS Two hundred patients underwent EUS-FNA (n = 97, HNP; n = 103, NNP) over a 22-month period. A significantly lower median number of passes was required for HNP than for NNP (2 vs. 3; p < .001). There was no significant difference in diagnostic accuracy between the two groups. The rate of obtaining a histological sample larger than a 10× power field in length was significantly higher for HNP than for NNP (76.4% vs. 59.6%; p = .0019). In the multivariate analysis, a large tumor size (>20 mm) and HNP were identified as factors influencing the acquisition of a larger histological sample. CONCLUSIONS There was no significant difference in diagnostic accuracy between HNP and NNP. HNP required fewer passes without ROSE and was related to the acquisition of a larger histological sample. HNP may be useful when few samples are available for EUS-FNA with NNP or a larger histological sample is needed.

Abstract
BACKGROUND/OBJECTIVES A clear criterion for terminating endoscopic ultrasound fine needle aspiration (EUS-FNA) without rapid on-site evaluation (ROSE) has not been established. However, a possible solution includes gross visual inspection (GVI) of the sample obtained with EUS-FNA. We performed a retrospective study to elucidate the efficacy of GVI for the diagnostic yield of EUS-FNA. METHODS Patients who underwent EUS-FNA of a pancreatic mass using a standard 22-G needle from January 2017 to December 2017 were included in the study. At least two punctures were performed for each patient, and GVI was performed for each pass by endoscopists. The correlation between GVI and pathological findings were investigated per needle pass for the first two passes. Regarding GVI, we evaluated the presence of a visible core (with or without) and the sample quantity (large or small). RESULTS We evaluated 126 EUS-FNA specimens and analyzed 252 needle passes. A final diagnosis of malignancy was made for 119 patients (94%). Accuracy rates were 92.5% with a visible core and 70.0% without a visible core (p < 0.01), and 85.2% for large sample quantities and 70.2% for small sample quantities (p < 0.01). Univariate analysis indicated that the presence of a visible core and large sample quantity were associated with accuracy. Multivariate analysis indicated that only the presence of a visible core was significant. CONCLUSIONS GVI can predict the correct diagnosis when ROSE is unavailable. Evaluating the presence of a visible core is more sensitive than assessing the quantity of the sample obtained.

Abstract
The Papanicolaou Society of Cytopathology has recently proposed a standardized terminology and nomenclature guidelines for pancreatic cytology. However the risk of malignancy associated with the new guidelines has been scarcely studied. In this study, a series of pancreatic cytology cases obtained by endoscopic ultrasound-guided fine-needle aspiration from 294 Chinese patients were retrospectively re-categorized into six categories according the new guidelines. The risks of malignancy were 18.1% for “negative,” 20.0% for “neoplastic,” 57.1% for “nondiagnostic,” 69.2% for “atypical,” 87.5% for “suspicious,” and 100.0% for “positive” respectively. The area under the receiver operating characteristic curve was 0.93 (95% Confidence Interval, 0.90-0.96), which was significantly higher than that associated with old classification system (0.82; 95% Confidence Interval, 0.77-0.87) conventionally used in China. Our investigation demonstrated that the new guidelines have a greater ability of risk stratification than the old classification system conventionally used in China. This may be helpful in giving better predictions of malignancy, thus leading to more personalized treatment strategies.

Abstract
Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been applied to pancreatic lesions since the 1990s, and its use is now widespread. Improvements in endoscopic devices and sampling techniques have resulted in excellent diagnostic ability for solid pancreatic lesions. However, clinical improvements alone are not responsible for it; pathological aspects have also played important roles. Rapid on-site evaluation minimizes endoscopic procedures, although its value at improving the diagnostic ratio is still debated. Diagnostic efficacy differs by sample preparations (direct smear, cytospin, liquid-based cytology, cell block, and biopsy) and by staining methods (Papanicoloau, Diff-Quik, hematoxylin-eosin, and Giemsa). Several immunocytochemistry protocols aid in diagnosing epithelial components with cytological atypia and in differentiating various tumor types. One cytopathology diagnostic system is telecytology, which uses transmitted digital images and enables real-time diagnosis of EUS-FNA samples by expert cytologists at remote locations. However, EUS-FNA samples are useful for more than just diagnoses, as molecular analysis of these samples allows the identification of prognostic markers, such as genetic alterations in K-ras and EGFR. Expression of drug-metabolizing enzymes, human equilibrative nucleoside transporter 1, correlates with the response to gemcitabine-based chemotherapy. These pathology efforts have enhanced the diagnostic efficacy of EUS-FNA, thereby leading to better outcomes for patients with pancreatic diseases.

Abstract
Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) has become an essential tool in the management of multiple diseases. Its accuracy is related to different aspects of the technique, one of the most important being the experience and interaction of the endosonographer and pathologist. Certain studies over the past years have highlighted the importance of having rapid on-site evaluation (ROSE) of samples obtained at the time of EUS-FNA. We have reviewed the role of ROSE, performed by the same endosonographer, a cytotechnologist and an expert cytopathologist. The available data suggest that ROSE (either by the endosonographer, the cytotechnologist, or the cytopathologist) improves sample adequacy and diagnostic yield, with the best option to have ROSE performed by an expert cytopathologist. However, if non-ROSE accuracy is already very high, any improvement is harder to achieve.

Abstract
INTRODUCTION Telecytopathology for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been shown to be an alternative to rapid on-site evaluation (ROSE). Gastroenterologists (endosonographers) performing EUS-FNA can be trained to evaluate a specimen for adequacy. This study examined the ability of an endosonographer with focused cytopathologic training to assess the adequacy of pancreatic FNA specimens and transmit diagnostic images to a remotely located cytopathologist as compared to an experienced cytotechnologist. MATERIALS AND METHODS This was a retrospective study of consecutive pancreatic lesions sampled by EUS-FNA reviewed by an endosonographer and a cytotechnologist. The participants were assessed based on their ability to (1) determine adequacy, (2) locate and transmit representative cell groups, (3) provide a preliminary diagnosis, and (4) provide concordance with actual diagnosis. RESULTS 105 consecutive cases of EUS-FNA of the pancreas were analyzed, including: adenocarcinoma (n = 39), cyst (n = 17), neuroendocrine neoplasia (n = 7), pancreatitis (n = 14), benign pancreas (n = 9), other neoplasms (n = 6), suspicious/atypical (n = 3), and nondiagnostic (n = 10). The cytotechnologist demonstrated superiority in accuracy 92.7% versus 70% (P = 0.003) and subcategorization 95.0% versus 76% (P = 0.007). There was no difference in "broad" categorization (benign/malignant) between the endosonographer and cytotechnologist, 98% and 98.2% (P = 0.946), respectively. Also, there was no difference with regard to adequacy assessment (P = 0.29). A steady learning curve for the endosonographer was demonstrated in their cytologic assessment (P = 0.041). The endosonographer was shown to be able to remotely transmit diagnostic images to a pathologist. CONCLUSION An endosonographer with limited training can examine for specimen adequacy, transmit images, and demonstrate representative cell groups. Larger studies are required though preliminary results are encouraging.

Abstract
BACKGROUND Increasing numbers of incidental pancreatic lesions are being detected each year. Accurate characterisation of pancreatic lesions into benign, precancerous, and cancer masses is crucial in deciding whether to use treatment or surveillance. Distinguishing benign lesions from precancerous and cancerous lesions can prevent patients from undergoing unnecessary major surgery. Despite the importance of accurately classifying pancreatic lesions, there is no clear algorithm for management of focal pancreatic lesions. OBJECTIVES To determine and compare the diagnostic accuracy of various imaging modalities in detecting cancerous and precancerous lesions in people with focal pancreatic lesions. SEARCH METHODS We searched the CENTRAL, MEDLINE, Embase, and Science Citation Index until 19 July 2016. We searched the references of included studies to identify further studies. We did not restrict studies based on language or publication status, or whether data were collected prospectively or retrospectively. SELECTION CRITERIA We planned to include studies reporting cross-sectional information on the index test (CT (computed tomography), MRI (magnetic resonance imaging), PET (positron emission tomography), EUS (endoscopic ultrasound), EUS elastography, and EUS-guided biopsy or FNA (fine-needle aspiration)) and reference standard (confirmation of the nature of the lesion was obtained by histopathological examination of the entire lesion by surgical excision, or histopathological examination for confirmation of precancer or cancer by biopsy and clinical follow-up of at least six months in people with negative index tests) in people with pancreatic lesions irrespective of language or publication status or whether the data were collected prospectively or retrospectively. DATA COLLECTION AND ANALYSIS Two review authors independently searched the references to identify relevant studies and extracted the data. We planned to use the bivariate analysis to calculate the summary sensitivity and specificity with their 95% confidence intervals and the hierarchical summary receiver operating characteristic (HSROC) to compare the tests and assess heterogeneity, but used simpler models (such as univariate random-effects model and univariate fixed-effect model) for combining studies when appropriate because of the sparse data. We were unable to compare the diagnostic performance of the tests using formal statistical methods because of sparse data. MAIN RESULTS We included 54 studies involving a total of 3,196 participants evaluating the diagnostic accuracy of various index tests. In these 54 studies, eight different target conditions were identified with different final diagnoses constituting benign, precancerous, and cancerous lesions. None of the studies was of high methodological quality. None of the comparisons in which single studies were included was of sufficiently high methodological quality to warrant highlighting of the results. For differentiation of cancerous lesions from benign or precancerous lesions, we identified only one study per index test. The second analysis, of studies differentiating cancerous versus benign lesions, provided three tests in which meta-analysis could be performed. The sensitivities and specificities for diagnosing cancer were: EUS-FNA: sensitivity 0.79 (95% confidence interval (CI) 0.07 to 1.00), specificity 1.00 (95% CI 0.91 to 1.00); EUS: sensitivity 0.95 (95% CI 0.84 to 0.99), specificity 0.53 (95% CI 0.31 to 0.74); PET: sensitivity 0.92 (95% CI 0.80 to 0.97), specificity 0.65 (95% CI 0.39 to 0.84). The third analysis, of studies differentiating precancerous or cancerous lesions from benign lesions, only provided one test (EUS-FNA) in which meta-analysis was performed. EUS-FNA had moderate sensitivity for diagnosing precancerous or cancerous lesions (sensitivity 0.73 (95% CI 0.01 to 1.00) and high specificity 0.94 (95% CI 0.15 to 1.00), the extremely wide confidence intervals reflecting the heterogeneity between the studies). The fourth analysis, of studies differentiating cancerous (invasive carcinoma) from precancerous (dysplasia) provided three tests in which meta-analysis was performed. The sensitivities and specificities for diagnosing invasive carcinoma were: CT: sensitivity 0.72 (95% CI 0.50 to 0.87), specificity 0.92 (95% CI 0.81 to 0.97); EUS: sensitivity 0.78 (95% CI 0.44 to 0.94), specificity 0.91 (95% CI 0.61 to 0.98); EUS-FNA: sensitivity 0.66 (95% CI 0.03 to 0.99), specificity 0.92 (95% CI 0.73 to 0.98). The fifth analysis, of studies differentiating cancerous (high-grade dysplasia or invasive carcinoma) versus precancerous (low- or intermediate-grade dysplasia) provided six tests in which meta-analysis was performed. The sensitivities and specificities for diagnosing cancer (high-grade dysplasia or invasive carcinoma) were: CT: sensitivity 0.87 (95% CI 0.00 to 1.00), specificity 0.96 (95% CI 0.00 to 1.00); EUS: sensitivity 0.86 (95% CI 0.74 to 0.92), specificity 0.91 (95% CI 0.83 to 0.96); EUS-FNA: sensitivity 0.47 (95% CI 0.24 to 0.70), specificity 0.91 (95% CI 0.32 to 1.00); EUS-FNA carcinoembryonic antigen 200 ng/mL: sensitivity 0.58 (95% CI 0.28 to 0.83), specificity 0.51 (95% CI 0.19 to 0.81); MRI: sensitivity 0.69 (95% CI 0.44 to 0.86), specificity 0.93 (95% CI 0.43 to 1.00); PET: sensitivity 0.90 (95% CI 0.79 to 0.96), specificity 0.94 (95% CI 0.81 to 0.99). The sixth analysis, of studies differentiating cancerous (invasive carcinoma) from precancerous (low-grade dysplasia) provided no tests in which meta-analysis was performed. The seventh analysis, of studies differentiating precancerous or cancerous (intermediate- or high-grade dysplasia or invasive carcinoma) from precancerous (low-grade dysplasia) provided two tests in which meta-analysis was performed. The sensitivity and specificity for diagnosing cancer were: CT: sensitivity 0.83 (95% CI 0.68 to 0.92), specificity 0.83 (95% CI 0.64 to 0.93) and MRI: sensitivity 0.80 (95% CI 0.58 to 0.92), specificity 0.81 (95% CI 0.53 to 0.95), respectively. The eighth analysis, of studies differentiating precancerous or cancerous (intermediate- or high-grade dysplasia or invasive carcinoma) from precancerous (low-grade dysplasia) or benign lesions provided no test in which meta-analysis was performed.There were no major alterations in the subgroup analysis of cystic pancreatic focal lesions (42 studies; 2086 participants). None of the included studies evaluated EUS elastography or sequential testing. AUTHORS' CONCLUSIONS We were unable to arrive at any firm conclusions because of the differences in the way that study authors classified focal pancreatic lesions into cancerous, precancerous, and benign lesions; the inclusion of few studies with wide confidence intervals for each comparison; poor methodological quality in the studies; and heterogeneity in the estimates within comparisons.

Abstract
BACKGROUND/AIMS Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose gastrointestinal submucosal tumors (SMTs). Although rapid on-site evaluation (ROSE) has been reported to improve the diagnostic accuracy of EUS-FNA for pancreatic lesions, on-site cytopathologists are not routinely available. Given this background, the usefulness of ROSE by endosonographers themselves for pancreatic tumors has also been reported. However, ROSE by endosonographers for diagnosis of SMT has not been reported. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with ROSE by endosonographers for SMT, focusing on diagnosis of gastrointestinal stromal tumor (GIST), compared with that of EUS-FNA alone. METHODS Twenty-two consecutive patients who underwent EUS-FNA with ROSE by endosonographers for SMT followed by surgical resection were identified. Ten historical control subjects who underwent EUS-FNA without ROSE were used for comparison. RESULTS The overall diagnostic accuracy for SMT was significantly higher in cases with than without ROSE (100% vs. 80%, p=0.03). The number of needle passes by FNA with ROSE by endosonographers tended to be fewer, although accuracy was increased (3.3±1.3 vs. 5.9±3.8, p=0.06). CONCLUSIONS ROSE by endosonographers during EUS-FNA for SMT is useful for definitive diagnosis, particularly for GIST.

Abstract
BACKGROUND AND AIMS A side-port needle has been developed to improve diagnostic accuracy by obtaining more cellular material during EUS-guided FNA (EUS-FNA). We compared the accuracy rate of histology and the quality of histologic specimens from 22-gauge (G) side-port and standard needles for EUS-FNA of a solid pancreatic mass in a multicenter, prospective, randomized control trial. METHODS Between January 2013 and September 2013, 160 consecutive patients with a suspected solid pancreatic mass at 5 tertiary referral centers were enrolled. Patients were randomized to the 22G side-port needle or 22G standard needle group. The primary endpoint was the diagnostic accuracy of histology. Secondary endpoints were the quality of the histologic specimen (quantity of tissue, degree of GI contamination, and amount of blood). RESULTS An analysis of 154 patients (side-port, 76, vs standard, 78) was performed. Six patients were excluded because of no pancreatic mass on EUS. There was no significant difference in the rate of diagnostic accuracy of histology (side-port, 87% [66/76], vs standard, 82% [64/78]; P = .51). Samples that enabled histologic interpretation were obtained in 64% (47/73) and 43% (33/77) of patients from the side-port and standard groups, respectively (P = .009). No significant difference was seen in the degree of GI contamination and amount of blood between groups. CONCLUSIONS There was no significant difference in the accuracy rate of histology between needle types. The side-port needle was superior to the standard needle in terms of obtaining samples that enabled histologic interpretation.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely used to obtain a definitive diagnosis of pancreatic tumors. Good results have been reported for its diagnostic accuracy, with high sensitivity and specificity of around 90%; however, technological developments and adaptations to improve it still further are currently underway. The endosonographic technique can be improved when several tips and tricks useful to overcome challenges of EUS-FNA are known. This review provides various techniques and equipment for improvement in the diagnostic accuracy in EUS-FNA.

Abstract
Endoscopic ultrasound (EUS)-guided tissue acquisition has emerged over the last decade as an invaluable diagnostic tool in approaching the different pancreatic lesions. Given the safety and minimal invasiveness of this approach combined with the high diagnostic yield, it became the standard of care when dealing with different pancreatic pathologies. However, some variables regarding this procedure remain not fully understood. These can influence the diagnostic yield of the procedure and include the presence of the on-site cytopathologist, the type and size of the needle used as well as obtaining aspiration versus core biopsy, the number of passes and the sampling technique, and the role of suction and stylet use among others. We performed a comprehensive literature search using PubMed, Google Scholar, and Embase for studies that assessed these variables. Eligible studies were analyzed using several parameters such as technique and procedure, with the aim of reviewing results from an evidence-based standpoint.

Abstract
BACKGROUND Prior to withdrawing the EUS-FNA needle from the lesion, the stopcock of the suction syringe is closed to reduce contamination. Residual negative pressure (RNP) may persist in the needle despite closing the stopcock. AIMS To determine whether neutralizing RNP before withdrawing the needle will improve the cytology yield. METHODS Bench-top testing was done to confirm the presence of RNP followed by a prospective, randomized, cross-over study on patients with pancreas mass. Ten milliliters of suction was applied to the FNA needle. Before withdrawing the needle from the lesion, the stopcock was closed. Based on randomization, the first pass was done with the stopcock either attached to the needle (S+) or disconnected (S-) to allow air to enter and neutralize RNP and accordingly the second pass was crossed over to S+ or S-. On-site cytopathologist was blinded to S+/S-. RESULTS Bench tests confirmed the presence of RNP which was successfully neutralized by disconnecting the syringe (S-) from the needle. Sixty patients were enrolled, 120 samples analyzed. S+ samples showed significantly greater GI tract contamination compared to S- samples (16.7 vs. 6.7%, p = 0.03). Of the 53 patients confirmed to have pancreas adenocarcinoma, FNA using S- approach was positive in 49 (93%) compared to 40 using the S+ approach (76%, p = 0.02). CONCLUSIONS Despite closing the stopcock of the suction syringe, RNP is present in the FNA needle. Neutralizing RNP prior to withdrawing the needle from the target lesion significantly decreased GI tract contamination of the sample thereby improving the FNA cytology yield.

Abstract
Since 1980, when endoscopic ultrasonography (EUS) was invented, great progress has been made in the development of EUS devices and technology, and EUS-guided diagnosis and treatment of digestive diseases have been widely adopted. Because of its safety, effectiveness and minimal invasion, EUS-guided interventional diagnosis and treatment of digestive diseases have been widely applied in the clinical work, and more and more new technologies are being developed. In this paper, we review the recent progress of EUS for the interventional diagnosis and treatment of digestive diseases.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is the preferred method for biopsying the gastrointestinal tract, and rapid on-site cytological evaluation is considered standard practice. Our institution does not perform on-site evaluation; this study analyzes our overall diagnostic yield, accuracy, and incidence of nondiagnostic cases to determine the validity of this strategy. DESIGN Data encompassing clinical information, procedural records, and cytological assessment were analyzed for gastrointestinal EUS-FNA procedures (n = 85) performed at Vancouver General Hospital from January 2012 to January 2013. We compared our results with those of studies that had on-site evaluation and studies that did not have on-site evaluation. RESULTS Eighty-five biopsies were performed in 78 patients, from sites that included the pancreas, the stomach, the duodenum, lymph nodes, and retroperitoneal masses. Malignancies were diagnosed in 45 (53%) biopsies, while 24 (29%) encompassed benign entities. Suspicious and atypical results were recorded in 8 (9%) and 6 (7%) cases, respectively. Only 2 (2%) cases received a cytological diagnosis of 'nondiagnostic'. Our overall accuracy was 72%, our diagnostic yield was 98%, and our nondiagnostic rate was 2%. Our results did not significantly differ from those of studies that did have on-site evaluation. CONCLUSION Our study highlights that adequate diagnostic accuracy can be achieved without on-site evaluation.

Abstract
BACKGROUND Although on-site cytopathology services have a significant impact on efficiency and accuracy of EUS-guided FNA (EUS-FNA), the availability of this service is variable. OBJECTIVE To evaluate the impact of an intensive 2-day training program to educate endosonographers in EUS-related cytopathology. DESIGN Pilot study. SETTING Tertiary care medical center. SUBJECTS Six endosonographers (5 male, median age, 35 years) with minimal previous cytopathology exposure comprised the study cohort. METHODS Pre- and posttraining testing was administered. Training commenced with a cytopathology tutorial focusing on 4 performance measures: specimen adequacy, sample interpretation, specimen processing, and preliminary diagnosis. Eight live EUS-FNA cases were then performed, and study participants independently completed 4 questions based on performance measures for each case. The ability to independently smear and stain slides and operate a microscope was additionally assessed after a hands-on tutorial. MAIN OUTCOME MEASUREMENTS Comparison of pretraining and posttraining scores, improvement in performance measures for live cases, and ability to independently handle specimens and operate a microscope. RESULTS Compared with pretraining, mean posttraining test scores improved by 63% from 48 to 78 out of 100. Mean live case performance score was 95%. Performances improved from 89% on day 1 to 100% on day 2. After training, all endosonographers could independently smear/stain slides and operate a microscope. LIMITATIONS Long-term impact is unclear. CONCLUSIONS An intensive 2-day program was effective in training endosonographers in the basics of EUS-related cytopathology. Incorporating basic cytopathology in EUS fellowship curriculum will likely improve diagnostic performance of tissue acquisition procedures.

Abstract
BACKGROUND AND AIM Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can be inconclusive in diagnosing solid pancreatic masses. The aim of the present study was to evaluate the impact of an inconclusive EUS-FNA in the management of patients with solid pancreatic masses. METHODS This is a retrospective analysis of a prospective database of patients with solid pancreatic masses referred for EUS-FNA between December 2011 and December 2013. Consecutive patients with inconclusive initial EUS-FNA were included. Demographic, clinical, procedural and outcome data were analyzed. RESULTS Over the study period, 387 patients underwent EUS-FNA of solid pancreatic masses, of which 38 patients had inconclusive cytology. Of the 38 patients, 18 were categorized as atypical, two were categorized as indeterminate or suspicious for malignancy, and 18 were categorized as benign process. Subsequently, 24 (63.2%) patients achieved cytopathological diagnosis by repeat EUS-FNA (8), transcutaneous FNA (4) and surgery (12). Repeat EUS-FNA were done a median of 13 days after the index examination and resulted in conclusive diagnosis in 72.7% of cases. Five patients undergoing surgery were confirmed to have benign lesions. In 14 (36.8%) patients not receiving a positive cytopathological diagnosis, 11 were eventually confirmed to be malignant based on clinical outcome and imaging evidence. CONCLUSIONS Inconclusive EUS-FNA could lead to unnecessary surgical procedures in patients with resectable solid pancreatic masses if no cytopathological diagnosis is obtained through either repeat or alternative diagnostic modalities. Repeat EUS-FNA provided a conclusive diagnosis in a majority of cases, and therefore should be strongly considered ahead of other modalities.

Abstract
BACKGROUND Although rapid on-site cytologic evaluation provides high efficacy of EUS-guided FNA (EUS-FNA), its availability is limited. Alternatively, macroscopic on-site quality evaluation (MOSE) may increase the efficacy of EUS-FNA. OBJECTIVE To assess the efficacy of MOSE in estimating the adequacy of histologic core specimens obtained by EUS-FNA using a standard 19-gauge needle (19GN) for solid lesions. DESIGN A prospective pilot study. SETTING Tertiary-care referral center. PATIENTS One hundred patients with solid lesions (n = 111 lesions). INTERVENTIONS EUS-FNA using 19GN MAIN OUTCOME MEASUREMENTS: The relation of a macroscopic visible core (MVC) in the FNA specimens on MOSE with histologic core and the diagnostic yields were studied. RESULTS The feasibility of EUS-FNA using a 19GN was 99%. The final diagnoses were malignancy in 83 lesions and benign in 28. MOSE revealed MVC in 91.1% with the median length of 8 mm. Histologic core was confirmed in 78.9%. The receiver-operating characteristic curve of the length of MVC for the presence of histologic core showed the cut-off MVC length of 4 mm with area under the curve of .893. Comparisons of per-pass diagnostic yields showed significantly superior histologic, cytologic, and overall diagnostic yields in MVC ≥ 4 mm as compared with <4 mm. The multivariate analysis for false-negative pass identified lesion in the pancreas and MVC < 4 mm as significant risk factors. No adverse events were seen. LIMITATIONS Single center, limited operators CONCLUSION MVC of ≥4 mm on MOSE can be an indicator of specimen adequacy and can improve diagnostic yield; however, additional FNA may be recommended for pancreatic lesions.

Abstract
OBJECTIVE Rapid on-site evaluation (ROSE) of cytologic adequacy improves the diagnostic yield of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). However, on-site advice from a cytotechnologist or cytopathologist is not always available during EUS-FNA. To enhance endosonographers' ability to assess the adequacy of EUS-FNA specimens, we designed an intensive, 2-h interactive training program. The aim of this study was to determine the usefulness of the program. METHODS Four cytological pictures were selected by a trained cytotechnologist and board-certified cytopathologist from each of the seven patients who underwent EUS-FNA for pancreatic mass in Okayama University Hospital. In total, 28 pictures were used in this study. Twenty endosonographers and 14 cytologists with different levels of EUS-FNA experience evaluated cytological pictures independently before and after the training program. RESULTS Endosonographers' skill in evaluating the adequacy of EUS-FNA specimens was significantly improved after the completion of the training program (p < 0.001). In contrast, almost all cytologists correctly judged the adequacy of the specimens before taking the training program. CONCLUSIONS This intensive, 2-h interactive training program is useful for endosonographers and capable of improving ROSE of EUS-FNA specimens.

Abstract
Endoscopic ultrasound (EUS) has become an essential tool for the study of pancreatic diseases. Specifically, EUS plays a pivotal role evaluating patients with a known or suspected pancreatic mass. In this setting, differential diagnosis remains a clinical challenge. EUS-guided fine-needle aspiration (FNA) and fine-needle biopsy (FNB) have been proven to be safe and useful tools in this setting. EUS-guided FNA and FNB, by obtaining cytological and/or histological samples, are able to diagnose pancreatic lesions with high sensitivity and specificity. In this context, several methodological features, trying to increase the diagnostic yield of EUS-guided FNA and FNB, have been evaluated. In this review, we focus on the role of rapid on-site evaluation (ROSE). From data reported in the literature, ROSE may increase diagnostic yield of EUS-FNA specimens by 10%-30%, and thus, diagnostic accuracy. However, we should point out that many recent studies have reported adequacy rates of > 90% without ROSE, indicating that, perhaps, at high-volume centers, ROSE may not be indispensable to achieve excellent results. The use of ROSE can be considered important during the learning curve of EUS-FNA, and also in hospital with diagnostic accuracy rates < 90%.
