[PMID: 38779600 PMCID: PMC11108040 DOI: 10.4103/joc.joc_90_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 02/06/2024] [Accepted: 03/28/2024] [Indexed: 05/25/2024] Open
Abstract
Introduction The Papanicolaou Society of Cytopathology System for reporting Pancreaticobiliary Cytology (PSCPC) is a reliable method to classify pancreatic fine needle aspiration cytology (FNAC) smears. However, it is not without practical problems which can diminish the diagnostic accuracy of the cytological diagnosis. Aims and Objectives To determine the diagnostic pitfalls while reporting cytomorphology of pancreatic lesions according to PSCPC on correlating FNAC findings with histopathology. Materials and Methods Retrospective analysis of pancreatic FNAC smears received in the Department of Pathology of our tertiary care institute over a period of 2 years was done. The cytological diagnoses were classified according to the Papanicolaou Society of Cytopathology system of reporting pancreaticobiliary cytology and correlated with histopathology. The reasons of cyto-histological discordance were analyzed. Results Out of 50 cases in which both FNAC and biopsy of pancreatic lesions were done, 34 cases were positive/malignant (Category VI), eight cases were suspicious for malignancy (Category V), three cases were neoplastic (Category IV), two cases were atypical (Category III), two cases were negative for malignancy (Category II), and one case was non-diagnostic (Category I). Out of 50 cases, histopathology was non-diagnostic due to inadequate material in six cases. The cytological diagnoses were compared with histopathology in the remaining 44 cases. Categories III, IV V, and VI were considered as positive for neoplastic pathology. The sensitivity of FNAC to predict neoplastic pathology was 97.5%, while the specificity was 25%. The positive predictive value was 92.9%. Two cases reported as atypical (Category III) turned out to be adenocarcinoma on histopathology. One case reported as neuroendocrine tumor and two cases reported as adenocarcinoma on cytology displayed features of chronic pancreatitis on histology. One case reported as neoplastic mucinous cyst (Category IV) turned out to be adenocarcinoma on histology (limited concordance). Conclusion The cytopathologist needs to be wary of the potential pitfalls to improve the diagnostic accuracy of FNACs.

Impact of preoperative endoscopic procedures on adverse event rates after surgical resection for main-duct and mixed-type intraductal papillary mucinous neoplasms (IPMNs). Pancreatology 2024; 24:152-159. [PMID: 37981524 DOI: 10.1016/j.pan.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 10/08/2023] [Accepted: 11/11/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Main-duct (MD-) and mixed-type (MT-) IPMNs harbor an increased risk of pancreatic cancer and warrant surgical resection. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) are important in the diagnosis of IPMNs. The aim of this study was to investigate whether endoscopic procedures manipulating the MD impact postoperative adverse events in patients with MD- and MT-IPMNs. METHODS We performed a retrospective study of 369 patients who underwent resections for MD- or MT-IPMN at two tertiary centers (2000-2019). Multivariable logistic regression analyses were performed for postoperative adverse events to compare the risks between intervention (ERCP, EUS-FNA with branch duct (BD) aspirated, EUS-FNA with MD aspirated from the duct directly or cyst/mass arising from MD) versus no-intervention group. RESULTS 33.1 % of patients had a preoperative ERCP and 69.4 % had EUS-FNA. Postoperative adverse events included: 30-day readmission (12.7 %), delayed gastric emptying (13.8 %), pancreatic fistula (10.3 %), abdominal abscess (5.7 %), cardiopulmonary adverse events (11.4 %), and mortality (1.4 %). The model was adjusted for potential confounders. There were no significant differences between the ERCP and no-ERCP groups for specific adverse events. Compared to no-EUS-FNA groups, groups of EUS-FNA with BD aspiration and EUS-FNA with MD aspiration from the main pancreatic duct directly or cyst/mass arising from MD did not show a significant increase in specific adverse events. CONCLUSIONS Postoperative adverse events were not significantly increased among patients who had ERCP or EUS-FNA before surgical resection for MD- or MT-IPMNs. Endoscopic procedures directly sampling the MD can be safely pursued for diagnostic purposes in selected cases.

Abstract
Endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNA) of the pancreas is performed routinely in many endoscopic centers as part of the diagnostic set-up for suspected pancreatic cancer. The use of transesophageal bronchoscopic ultrasound-guided fine needle aspiration (EUS-B-FNA) by pulmonologists has expanded significantly, since it enables effective diagnosis of lesions in the mediastinum and upper abdomen. The following case demonstrates the safety and feasibility of EUS-B-FNA in a patient with non-small cell lung cancer (NSCLC) cancer and a pancreatic mass of unknown origin. A patient who was previously diagnosed with NSCLC was referred to the Department of Respiratory Medicine, Odense University Hospital due to suspected recurrence of NSCLC. The patient underwent endobronchial ultrasound guided (EBUS)-FNA from several suspected mediastinal lymph nodes and combined EUS-B-FNA from a pancreatic mass during the same procedure. Pathology results from the pancreatic mass and from the mediastinal lymph nodes showed squamous-cell carcinoma, metastasis from the previous NSCLC. We here by demonstrated that EUS-B-FNA is a feasible and safe technique to obtain tissue samples from pancreatic lesions in patients under investigation for lung cancer.

Abstract
Background and study aims Pancreatic duct (PD) cannulation may be difficult during conventional endoscopic retrograde cholangiopancreatography (ERCP) due to underlying pathology, anatomical variants or surgically altered anatomy. Pancreatic access in these cases previously necessitated percutaneous or surgical approaches. Endoscopic ultrasound (EUS) allows for an alternative and can be combined with ERCP for rendezvous during the same procedure, or for other salvage options. Patients and methods Patients with attempted EUS access of the PD from tertiary referral centers between 2009 and 2022 were included in the cohort. Demographic data, technical data, procedural outcomes and adverse events were collected. The primary outcome was rendezvous success. Secondary outcomes included rates of successful PD decompression and change in procedural success over time. Results The PD was accessed in 105 of 111 procedures (95 %), with successful subsequent ERCP in 45 of 95 attempts (47 %). Salvage direct PD stenting was performed in 5 of 14 attempts (36 %). Sixteen patients were scheduled for direct PD stenting (without rendezvous) with 100 % success rate. Thus 66 patients (59 %) had successful decompression. Success rates improved from 41 % in the first third of cases to 76 % in the final third. There were 13 complications (12 %), including post-procedure pancreatitis in seven patients (6 %). Conclusions EUS-guided anterograde pancreas access is a feasible salvage method if retrograde access fails. The duct can be cannulated, and drainage can be achieved in the majority of cases. Success rates improve over time. Future research may involve investigation into technical, patient and procedural factors contributing to rendezvous success.

Abstract
While approximately 85% of neoplasms are ductal pancreatic adenocarcinomas (DPA), adenosquamous pancreatic carcinoma (APC) is a rare subtype of pancreatic cancer that exhibits aggressive behavior and poor prognosis. The authors report three cases of primary APC diagnosed through endoscopic ultrasound-guided tissue acquisition (EUS-TA) using the new ProCore 20G needle, which had been developed to improve fine-needle aspiration results by providing more tissue for histopathology. Given its ability for microcore retrieval, pancreatic stroma examination, and excellent histopathology results, EUS-TA has exhibited exceptional diagnostic yield among patients with solid pancreatic lesions. All three APC cases presented herein had been accurately diagnosed using immunohistochemistry after microcore acquisition.

Abstract
Endoscopic ultrasound (EUS) gained wide acceptance as the diagnostic and minimally invasive therapeutic approach for intra-luminal and extraluminal gastrointestinal, as well as various non-gastrointestinal lesions. Since its introduction, EUS has undergone substantial technological advances. This multi-centric study is a retrospective analysis of a prospectively maintained database of patients who underwent EUS for the evaluation of lesions located within the gastrointestinal tract and the proximal organs. It aimed to extensively assess in dynamic the dual-center EUS experience over the course of the past 20 years. Hence, we performed a population study and an overall assessment of the EUS procedures. The performance of EUS-FNA/FNB in diagnosing pancreatic neoplasms was evaluated. We also investigated the contribution of associating contrast-enhanced ultrasound imaging (CE-EUS) with EUS-FNA/FNB for differentiating solid pancreatic lesions or cystic pancreatic lesions. A total of 2935 patients undergoing EUS between 2002–2021 were included, out of which 1880 were diagnostic EUS and 1052 EUS-FNA/FNB (80% FNA and 20% FNB). Therapeutic procedures performed included endoscopic transmural drainage of pancreatic fluid collections, celiac plexus block and neurolysis, while diagnostic EUS-like CE-EUS (20%) and real-time elastography (12%) were also conducted. Most complications occurred during the first 7 days after EUS-FNA/FNB or pseudocyst drainage. EUS and the additional tools have high technical success rates and low rates of complications. The EUS methods are safe, cost effective and indispensable for the diagnostic or therapeutic management in gastroenterological everyday practice.

Abstract
Background and Objectives Standard suction technique (SST), slow-pull technique (SPT), and wet suction technique (WEST) of EUS-FNA are designed to improve the diagnostic yields of solid and solid-cystic lesions. We conducted a multicenter, prospective, randomized crossover trial to compare SST, SPT, and WEST on specimen quality and diagnostic accuracy using a 22G needle. Methods Patients with solid or solid-cystic lesions referred for EUS-FNA at four tertiary hospitals from December 2017 to August 2019 were considered eligible. All lesions were sampled using a 22G needle by the three techniques performed consecutively in a randomized order. The primary outcome was quality of the specimen acquired by each technique regarding blood contamination, tissue integrity and cellularity for diagnosis, graded on a predefined scale. The secondary outcomes were the diagnostic yield of EUS-FNA and the incidence of adverse events. ClinicalTrial. gov registration number: NCT03567863. Results A total of 300 patients (mean age, 60.6 years, 188 men) were enrolled. WEST was superior (mean score 4.02 ± 1.51) over SST (3.67 ± 1.57, P = 0.018), but comparable to SPT (3.83 ± 1.55, P = 0.370) in overall specimen quality evaluation. WEST produced better tissue integrity (1.42 ± 0.74) and higher cellularity (1.32 ± 0.80) than SST and SPT. SPT (1.43 ± 0.69) was superior to SST (1.27 ± 0.72, P = 0.004) and WEST (1.28 ± 0.71, P = 0.006) in avoiding blood contamination. WEST achieved a diagnostic accuracy of 74.7%, higher than SST (64.4%, P = 0.007) and SPT (65.0%, P = 0.012). One bleeding event occurred with a pancreatic lesion. Conclusions WEST was comparable to SPT and superior to SST in the overall quality of the specimen and achieved highest diagnostic yield.

Abstract
Backgrounds/Aims Metastatic lesions of the pancreas (PMET) account for 1%–5% of all malignant solid pancreatic lesions (SPL). In this study we evaluated the utility of endoscopic ultrasonography with fine needle aspiration (EUS-FNA) in diagnosing PMET. Methods Patients who underwent EUS-FNA at a community referral center between 2011–2017 for SPL were identified. Clinical, radiologic, and EUS-FNA features of those with PMET were compared to those with primary solid tumors of the pancreas: pancreatic adenocarcinoma (PDAC) and neuroendocrine tumors (PNET). Results A total of 191 patients were diagnosed with solid pancreatic malignancy using EUS-FNA: 156 PDAC, 27 PNET, and eight (4.2%) had PMET. Patients with PMET were less likely to have abdominal pain (25.0% vs. 76.3% vs. 48.2%; p < 0.01) or obstructive jaundice (37.5% vs. 58.3% vs. 0%; p < 0.01) compared to PDAC and PNET. Those with PMET were more likely to have mass lesions with/without biliary or pancreatic ductal dilatations (100% vs. 86.5% vs. 85.2%; p < 0.01) and lower CA19-9 (82.5 ± 43.21 U/mL vs. 4,639.30 ± 11,489.68 U/mL vs. 10.50 ± 10.89 U/mL; p < 0.01) compared to PDAC and PNET. Endosonographic features were similar among all groups. Seven (87.5%) patients with PMET had a personal history of malignancy prior to PMET diagnosis. The primary malignancy was renal cell carcinoma in five PMET. Conclusions PMET are exceedingly rare, comprising less than 5% of SLP. Patients with PMET are less likely to present with symptoms and mostly identified by surveillance imaging for the primary malignancy.

Abstract
There is no reason to be pollyannaish when approaching patients with malignant biliary obstruction (MBO). Although technology has allowed refining diagnosis and resectability of cancers causing biliary obstruction, outcomes have not improved significantly. The previous preponderant place of surgical procedures now is replaced by endoluminal and percutaneous techniques for the management of symptoms of MBO. Because quantity of life often is the primary and sole outcome for evaluation of various interventions, the main focus of patient quality of life may be erroneously deemphasized. Lagging behind scientific advances are the availability of palliative care services and studies of patient-related outcomes.

Abstract
Pancreatic neuroendocrine tumors (PanNETs) are rare neoplasms that include even rarer variants that may pose different diagnostic problems, especially in fine needle aspiration cytology (FNAC). We describe the diagnostic clues of the amyloid-rich variant of PanNETs in endoscopic ultrasound (EUS)-guided fine needle aspiration cytology (EUS-FNAC). Three cases of PanNETs with an amyloid-rich stromal component were retrieved and retrospectively reviewed. For every case, the pancreatic lesion was investigated by a EUS-FNAC procedure. The final diagnosis was supported by immunocytochemistry and Congo red staining. All cases had similar EUS-FNAC features: neoplastic cells were entrapped in an eosinophilic, homogeneous dense and amorphous matrix. The neuroendocrine nature was confirmed by immunoexpression of synaptophysin and chromogranin A, while the amorphous stroma was characterized as amyloid based on positive Congo red staining. Regarding the hormonal profile, no insulin or proinsulin reactivity was observed, but all cases were diffusely positive for amylin. The diagnosis of uncommon variants of PanNETs, such as the amyloid-rich, is challenging especially in EUS-FNAC procedures because of a unique and misleading morphology, potentially mimicking fibrotic conditions and amyloid deposition within systemic amyloidosis. In cytology specimens, the presence of amorphous material requires amyloid deposition to be considered in the differential diagnosis of pancreatic neoplasms with neuroendocrine phenotype.

Abstract
A presumed benign cystic tumor in the pancreatic head had been pointed out to a 78-year-old man 4 years ago. In addition to no communication between the tumor and the main pancreatic duct, magnetic resonance imaging showed that the cystic fluid was serous. Gradual tumor enlargement from 2.1 to 4.0 cm urged us to resect the tumor. In order to safely enucleate the tumor, we preoperatively placed a pancreatic duct stent and covered the pancreatic parenchyma with a polyglycolic acid sheet, fibrin glue, and thrombin after tumor enucleation. The patient postoperatively developed grade B pancreatic fistula but recovered with antibiotics therapy. Postoperative computed tomography showed successful preservation of the main pancreatic duct. Pathological study showed a well-defined tumor mainly composed of loosely textured and S-100-positive spindle cells with abundant and hyalinized blood vessels in the cystic walls with palisading spindle cells, leading to the diagnosis of Antoni B schwannoma. The patient was discharged on the 11th day after operation. Both pancreatic duct stunting and covering the exposed pancreatic parenchyma with a polyglycolic acid sheet, fibrin glue, and thrombin are feasible measures to enucleate large benign tumors in the pancreatic head.

Abstract
BACKGROUND Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) is important for the differential diagnosis of solid pancreatic lesions. Sample adequacy is related to the number of needle passes, and European guidelines recommend three to four needle passes with a standard EUS-FNA needle. We aimed to evaluate the optimal number of passes with standard EUS-FNA needles in solid pancreatic lesions. METHODS Patients with solid pancreatic masses without cystic component >20% on computed tomography scan, and without biliary metallic stents, or coagulation problems were included prospectively. Standard 22G needles were used (maximum four passes); each sample was paraffin-embedded and analyzed separately. Final diagnosis was established by EUS-FNA, repeat EUS-FNA, surgery, or follow-up. RESULTS Sixty-one of 65 patients were included. The final diagnoses were adenocarcinoma (n = 44, 72%), neuroendocrine tumor (NET) (n = 10, 16%), metastasis (n = 1, 4%) and nonmalignant lesion (n = 6, 10%). Immunohistochemical staining was possible in 17 cases. The diagnosis was established by the first pass in 62% of cases (n = 38), by the second in 15% (n = 9), by the third in 15% (n = 9), and by the fourth in 3% (n = 2). The diagnostic accuracy for all four passes compared to the first three passes was 95% vs 92% (P = .5). The contribution of the fourth pass was not different between adenocarcinoma and NET (2% vs 10%, respectively; P = .667). CONCLUSION Three passes with standard EUS-FNA was optimal for a specific diagnosis of solid pancreatic masses, regardless of the histological type of the lesion.

Endoscopic Ultrasound-Guided Fine-Needle Aspiration (EUS-FNA) with Image Enhancement. Diagnostics (Basel) 2020; 10:diagnostics10110888.

Abstract
Although endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is useful in the differential diagnosis of solid pancreatic lesions, lymph nodes, and liver lesions, inadequate sampling may result in an incorrect pathological diagnosis. The accuracy of EUS for the evaluation of pancreatobiliary lesions may be increased by image enhancement technologies, including contrast-enhanced harmonic (CH)-EUS and EUS-elastography. These methods can provide information that complement EUS-FNA for the diagnosis and staging of pancreatobiliary cancer, and can help to identify the EUS-FNA target, reducing the requirement for repeat FNA.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) has emerged as a safe, efficacious alternative to fine needle aspiration (FNA) for tissue acquisition. EUS-FNB is reported to have higher diagnostic yield while preserving specimen tissue architecture. However, data on the optimal method of EUS-FNB specimen processing is limited.
AIM To evaluate EUS-FNB with specimen processing as histology vs EUS-FNA cytology with regards to diagnostic yield and specimen adequacy.
METHODS All EUS-FNA and EUS-FNB performed at our institution from July 1, 2016, to January 31, 2018, were retrospectively analyzed. We collected data on demographics, EUS findings, pathology, clinical outcomes, and procedural complications in two periods, July 2016 through March 2017, and April 2017 through January 2018, with predominant use of FNB in the second data collection time period. FNA specimens were processed as cytology with cell block technique and reviewed by a cytopathologist; FNB specimens were fixed in formalin, processed for histopathologic analysis and immunohistochemical staining, and reviewed by an anatomic pathologist. Final diagnosis was based on surgical pathology when available, repeat biopsy or imaging, and length of clinical follow up.
RESULTS One hundred six EUS-FNA and EUS-FNB procedures were performed. FNA alone was performed in 17 patients; in 56 patients, FNB alone was done; and in 33 patients, both FNA and FNB were performed. For all indications, diagnostic yield was 47.1% (8/17) in FNA alone cases, 85.7% (48/56) in FNB alone cases, and 84.8% (28/33) in cases where both FNA and FNB were performed (P = 0.0039). Specimens were adequate for pathologic evaluation in 52.9% (9/17) of FNA alone cases, in 89.3% (50/56) of FNB alone cases, and 84.8% (28/33) in cases where FNA with FNB were performed (P = 0.0049). Tissue could not be aspirated for cytology in 10.0% (5/50) of cases where FNA was done, while in 3.4% (3/89) of FNB cases, tissue could not be obtained for histology. In patients who underwent FNA with FNB, there was a statistically significant difference in both specimen adequacy (P = 0.0455) and diagnostic yield (P = 0.0455) between the FNA and FNB specimens (processed correspondingly as cytology or histology).
CONCLUSION EUS-FNB has a higher diagnostic yield and specimen adequacy than EUS-FNA. In our experience, specimen processing as histology may have contributed to the overall increased diagnostic yield of EUS-FNB.

Abstract
UNLABELLED To explore the diagnostic value of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for small, solid or semi-solid pancreatic lesions (≤20 mm) and the factors affecting its accuracy. METHODS Altogether 92 patients with small, solid or semi-solid pancreatic lesions who underwent EUS-FNA at the Nanjing Drum Tower Hospital from November 2009 to January 2019 were retrospectively analyzed. Univariate and multivariate analyses were used to determine the factors affecting the accuracy of EUS-FNA for detecting these lesions. RESULTS Among the 92 cases, 56 (60.9%) were diagnosed as having malignant lesions and 36 (39.1%) as benign lesions, respectively. The overall sensitivity, specificity and accuracy of EUS-FNA for the diagnosis of small, solid or semi-solid pancreatic lesions were 71.4%, 100% and 82.6%, respectively. When considering the impact of the presence of a tissue core on the diagnosis, the sensitivity, specificity, and accuracy of EUS-FNA with tissue core compared with those based on cytology alone were 77.3% vs 50.0%; 100% vs 100%; and 86.8% vs 62.5%, respectively. The multivariate analysis showed that larger tumor size (>15-20 mm) (odds ratio [OR] 4.200, 95% confidence interval [CI] 1.21-14.53, P = 0.023) and histologic diagnosis based on tissue core (OR 4.593, 95% CI 1.03-20.47, P = 0.046) were related to a higher accuracy of EUS-FNA. Adverse events were observed in three patients, all were treated conservatively and recovered within 3 days. CONCLUSIONS EUS-FNA is effective and safe for diagnosing small pancreatic lesions. Tumor size and presence of tissue core are related to higher accuracy of the EUS-FNA.

The diagnostic performance of novel torque technique for endoscopic ultrasound-guided tissue acquisition in solid pancreatic lesions: A prospective randomized controlled trial. J Gastroenterol Hepatol 2020; 35:508-515. [PMID: 31425640 DOI: 10.1111/jgh.14840] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2019] [Revised: 08/14/2019] [Accepted: 08/15/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIM Although several techniques for improved outcomes in endoscopic ultrasound (EUS)-guided tissue acquisition have been reported, the reported diagnostic yield for pancreatic masses is not satisfactory. The effects of novel technique (torque method) on twisting the scope in the clockwise or counterclockwise direction during EUS-fine needle biopsy (EUS-FNB) are unknown. We compared the diagnostic yield of EUS-FNB for pancreatic masses using the torque and standard techniques. METHODS From April 20, 2017, to March 16, 2018, 124 consecutive patients with solid pancreatic mass who underwent EUS-FNB using either the torque or standard technique were randomly assigned. Three passes were made with each technique, comprising 10 uniform to-and-fro movements on each pass with a 10-mL syringe suction. The primary outcome was procurement rates of histologic cores, and the secondary outcomes were the diagnostic performance and technical failure. RESULTS There were significant differences between the groups regarding the procurement rate of the histologic core and optimal quality core (standard vs torque: 87.1% [54/62] vs 98.4% [61/62], P = 0.038 and 79.0% [49/62] vs 93.5% [58/62], P = 0.037). The sensitivity, specificity, positive predictive value, and negative predictive values of EUS-FNB were 85.45%, 100%, 100%, and 46.67%, respectively, for the standard technique and 96.49%, 100%, 100%, and 71.43%, respectively, for the torque technique. The diagnostic accuracies of the standard and torque techniques were 87.10% and 96.77%, respectively. CONCLUSIONS The torque technique for EUS-FNB offered acceptable technical feasibility and superior diagnostic performance, including optimal histologic core procurement, compared with the standard technique.

Abstract
BACKGROUND AND AIM In chronic pancreatitis (CP) patients, diagnosis of small pancreatic lesions by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is challenging. Thus, the aim of the present study was to investigate whether CP influences the diagnostic ability of EUS-FNA for pancreatic lesions ≤10 mm. METHODS One hundred and seventeen patients who underwent EUS-FNA for pancreatic lesions ≤10 mm in size were enrolled. Patients were classified into two groups based on features of CP observed by EUS (EUS-CP features) in accordance with the Rosemont classification. The CP group was defined as cases consistent with CP or suggestive of CP, and the non-CP group was defined as cases indeterminate for CP or normal. Factors influencing the diagnostic accuracy of EUS-FNA and CP status in pancreatic tumors were also investigated. RESULTS Diagnostic ability of EUS-FNA (overall cases, non-CP vs CP) had sensitivity (80.4%, 96.7% vs 57.1%; P < 0.001), specificity (100%, 100% vs 100%; P > 0.05), and accuracy (91.5%, 98.6% vs 80.4%; P = 0.001). In multivariate analysis of factors influencing the accuracy of EUS-FNA, CP significantly lowered the accuracy (P = 0.048; odds ratio [OR] = 9.21). Among pancreatic cancer patients, the number of CP patients was significantly higher than the number of patients with benign lesions (P = 0.023). In multivariate analysis, lobularity without honeycombing was more frequently observed in cases of pancreatic cancer (P = 0.018; OR, 12.65). CONCLUSION Endoscopic ultrasound-guided FNA offers high accuracy for small pancreatic lesions ≤10 mm. However, in cases with CP, the diagnostic ability of EUS-FNA is significantly reduced.

Abstract
Background/Aims Endoscopic ultrasound (EUS)-guided fine-needle aspiration is very effective for providing specimens for cytological evaluation. However, the ability to provide sufficient tissue for histological evaluation has been challenging due to the technical limitations of dedicated core biopsy needles. Recently, a modified EUS needle has been introduced to obtain tissue core samples for histological analysis. We aimed to determine (1) its ability to obtain specimens for histological assessment and (2) the diagnostic accuracy of EUS-guided fine-needle biopsy (EUS-FNB) using this needle.
Methods We retrospectively analyzed consecutive cases of FNB using modified EUS needles for 342 lesions in 303 patients. The cytology and histological specimens were analyzed. Diagnostic accuracy was calculated.
Results Adequate cytological and histological assessment was possible in 293/342 (86%) and 264/342 (77%) lesions, respectively. Diagnostic accuracy of the cytological specimen was 294/342 (86%) versus 254/342 (74%) for the histological specimen (p<0.01). Diagnostic accuracy of the combined cytological and histological assessment was 323/342 (94.4%), which was significantly higher than that of both histology alone (p<0.001) and cytology alone (p=0.001).
Conclusions EUS-FNB with the modified EUS needle provided histologic tissue cores in the majority of cases and achieved excellent diagnostic accuracy with few needle passes.

Abstract
Background: It is difficult to diagnose the cause of abdominal lymphadenopathy without determining the primary lesions. With the advent of curved ultrasound endoscopy, EUS-FNA can sample lymph nodes safely, accurately and conveniently. Due to the lack of formal quantitative and comprehensive literature review to determine the diagnostic value of EUS-FNA in the diagnosis of enlarged intra-abdominal lymph nodes of unknown origin, we conducted this study to systematically evaluate the diagnostic accuracy of EUS-FNA in the enlarged intra-abdominal lymph nodes.Methods: We performed a systematic review and meta-analysis to evaluate the accuracy of EUS-FNA for the diagnosis of intra-abdominal lymphadenopathy. We searched PubMed, Embase, and Cochrane Library to collect related studies and diagnostic performance data. We used a random-effects model to estimate the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio (DOR). Heterogeneity was assessed by subgroup and meta-regression analysis.Results: Twelve eligible studies involved 774 patients were identified. The pooled sensitivity and specificity of all studies is 94% (95% CI: 91% to 96%) and 98% (95% CI: 96% to 99%), respectively. The pooled positive and negative likelihood ratios are 17.44 (95% CI, 6.50 to 46.79) and 0.09 (95% CI: 0.06 to 0.14). The pooled DOR is 277.82 (95% CI, 97.65 to 790.46).Conclusions: EUS-FNA is a safe and feasible technique with high sensitivity and specificity for the diagnosis of abdominal lymph node enlargement. Considering the limitations and heterogeneity, high-quality studies are needed to further explore the diagnostic value of EUS-FNA.

Abstract
Background/Aims Determining the cause of suspected biliary stricture is often challenging in clinical practice. We aimed to compare the diagnostic yields of endoscopic ultrasound-guided tissue sampling (EUS-TS) and endoscopic retrograde cholangiopancreatography-guided tissue sampling (ERCP-TS) in patients with suspected biliary stricture at different primary lesions. Methods We enrolled patients who underwent same-session EUS- and ERCP-TS for the evaluation of suspected biliary stricture. Forceps biopsy and/or brush cytology of intraductal lesions and fine-needle aspiration for solid mass lesions were performed during ERCP and EUS, respectively. Results One hundred and twenty-five patients treated at our institution between January 2011 and September 2016, were initially considered for the study. However, 32 patients were excluded due to loss of follow-up (n=8) and ERCP-TS on the pancreatic duct (n=20) or periampullary lesions (n=4). Of the 93 patients included, 86 had a malignant tumor including cholangiocarcinoma (n=39), pancreatic cancer (n=37), and other malignancies (n=10). Seven patients had benign lesions. EUS-TS had higher rate of overall diagnostic accuracy than ERCP-TS (82.8% vs. 60.2%, p=0.001), and this was especially true for patients with a pancreatic lesion (84.4% vs. 51.1%, p=0.003). Conclusions EUS-TS was found to be superior to ERCP-TS for evaluating suspected biliary strictures, especially those caused by pancreatic lesions.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration fails to diagnose up to 25% of patients with pancreatic ductal adenocarcinoma (PDAC). Proteomics can help to overcome this clinical dilemma. We hypothesized that soluble protein signatures can differentiate PDAC from benign tissues. STUDY DESIGN Tissues were obtained from resected surgical specimens, lysed, and homogenates collected for analysis with a 41-protein multiplex assay. Analyte concentrations were normalized to total protein. Statistical analysis was performed to evaluate for differences in PDAC vs benign tissue. RESULTS Tissues were obtained from 159 patients, 82 patients with PDAC naïve to therapy and 77 with benign pancreatic pathology. Fourteen analytes had a receiver operating characteristic curve area of >0.75 for predicting PDAC vs benign tissue. A recursive partitioning model using only 2 analytes, interleukin 1 receptor antagonist and transforming growth factor-α, provided an accuracy, sensitivity, and specificity of 91.2%, 90.2%, and 92.2%, respectively. A penalized logistic regression model found 12 analytes that provide diagnostic value to a protein signature. The mean area under the receiver operating characteristic after 50 tenfold cross-validations was 0.951. Accuracy, sensitivity, and specificity of this model were 91.2%, 87.8%, and 94.8%, respectively. Applying the scenario of 80% disease prevalence in patients undergoing endoscopic ultrasound with fine-needle aspiration for a pancreatic head mass, positive predictive value is 98.5% (95% CI 93.0% to 99.7%) and negative predictive value is 66.0% (95% CI 54.9% to 75.6%). CONCLUSIONS Protein signatures from pancreatic specimens can differentiate PDAC from benign tissue. Additional work to validate these findings in a unique sample set is warranted.

Abstract
BACKGROUND Although endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been widely used for the diagnosis of pancreatic tumors, the ability to obtain adequate pancreatic tumor tissue needs to be improved. AIMS This study was performed to compare a newly designed 21-gauge needle (EUS Sonopsy CY; Hakko Medical, Nagano, Japan) and a standard 22-gauge needle for tissue sampling of solid pancreatic masses. METHODS Consecutive patients with solid pancreatic masses who underwent EUS-FNA with either the EUS Sonopsy CY or the 22-gauge needle from June 2014 to December 2016 were enrolled. The primary outcome was comparison of the diagnostic yield of the FNA samples. The secondary outcomes were comparison of technical success, diagnostic ability for malignancy, and complications. RESULTS A total of 93 patients (40.9% female; mean age, 70.1 years) underwent EUS-FNA with the EUS Sonopsy CY (n = 47) or the standard 22-gauge needle (n = 46). The technical success rate was 100% in both groups, and the overall diagnostic accuracy for malignancy was similar between the groups (100% in the EUS Sonopsy CY group vs. 95.7% in the 22-gauge needle group, P = 0.242). Nevertheless, the EUS Sonopsy CY resulted in significantly higher scores for cellularity (P = 0.006) and lower scores for blood contamination (P < 0.001). The procedure-related complication rate was comparable between the groups (P = 0.148). CONCLUSIONS The EUS Sonopsy CY provided higher-quality specimens for histological evaluation in terms of both sample cellularity and blood contamination for the diagnosis of solid pancreatic masses. TRIAL REGISTRATION The study was registered in a clinical trial registry, No. UMIN000032598.

Abstract
Fine needle aspiration (FNA) is currently the standard of care for sampling pancreatic solid masses by using endoscopic ultrasound (EUS). The accuracy of the technique is reported to be high, especially if coupled with the rapid on site evaluation (ROSE), and it has a high safety profile. However, FNA presents some limitations, such as the small amount of tissue that can be collected and the inability of obtaining a core tissue with intact histological architecture, which is relevant to perform immunohistochemical analysis, molecular profiling and, therefore, targeted therapies. Moreover, the presence of the ROSE by an expert cytopathologist is very important to maximize the diagnostic yield of FNA technique; however, it is not widely available, especially in small centers. Hence, the introduction of EUS fine needle biopsy (FNB) with a new generation of needles, which show a high safety profile too and a satisfying diagnostic accuracy even in the absence of ROSE, could be the key to overcome the limitations of FNA. However, FNB has not yet shown diagnostic superiority over FNA. Considering all the technical aspects of FNA and FNB, the different types of needle currently available, comparisons in term of diagnostic yield, and the different techniques of sampling, a tailored approach should be used in order to determine the needle that is most appropriate for the different specific scenarios.

Abstract
BACKGROUND AND AIMS Pancreatic solid masses (PSM) are difficult to assess; endoscopic ultrasound with fine-needle aspiration (FNA) enables tissue acquisition, but has high false-negative rates. Quantitative elastography (QE) predicts diagnosis on the basis of the strain ratio (SR). We aimed to compare both methods to evaluate PSM. MATERIALS AND METHODS This prospective study, carried out between January and December 2016, included suspected PSM cases; those with advanced disease and cystic components were excluded. Both procedures were performed; histologic information was obtained for the final diagnoses. Diagnostic tests and receiver-operating characteristic curve were calculated. P<0.05 was considered statistically significant. RESULTS We included 134 patients (53% women; mean, 53±16.2 y). The median tumor size was 30 (10 to 78) mm, with 69.4% and 30.6% malignant and benign tumors (median SR: 19.5 vs. 7.5; P=0.000), respectively, and 87% were pancreatic adenocarcinoma. QE with SR cutoff ≥10 showed similar parameters to FNA in both PSM types: sensitivity, 94% in both; specificity, 85% versus 87%; positive predictive value, 93% versus 94%; negative predictive value, 87% in both; and accuracy, 92% for malignant and sensitivity, 85% versus 87%; specificity, 94% in both; positive predictive value, 87% in both; negative predictive value, 93% versus 94%; and accuracy, 92% for benign. The area under the curve was 0.96 (P<0.000; 95% confidence interval, 0.940-0.995). New classifications on the basis of positive likelihood ratio were grouped as follows: A ≤8.7 (benign tumor); B >8.7 to <15.5 (indeterminate); and C ≥15.5 (malignant). CONCLUSIONS QE has similar capacity to FNA in PSM evaluation. However, the former can be used potentially as a substitute of the latter in certain cases on the basis of these new SR cutoff-based classifications.

Abstract
BACKGROUND Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has high diagnostic accuracy for pancreatic diseases. However, the effect of mass size on diagnostic accuracy has yet to be determined, especially for small pancreatic lesions. We aimed to determine the effect of pancreatic mass size on the diagnostic yield of EUS-FNA. METHODS We searched the database in Hokkaido University Hospital between May 2008 and December 2016 and identified solid pancreatic lesions examined by EUS-FNA. All lesions were stratified into five groups based on mass sizes: groups A (< 10 mm), B (10-20 mm), C (20-30 mm), D (30-40 mm) and E (≥ 40 mm). The sensitivity, specificity, diagnostic accuracy and adverse event rate were retrospectively evaluated. RESULTS We analyzed a total of 788 solid pancreatic lesions in 761 patients. The patients included 440 males (57.8%) with a mean age of 65.7 years. The sensitivities in groups A (n = 36), B (n = 223), C (n = 304), D (n = 147) and E (n = 78) were 89.3%, 95.0%, 97.4%, 98.5% and 98.7%, respectively, and they significantly increased as the mass size increased (P < 0.01, chi-squared test for trend). The diagnostic accuracies were 91.7%, 96.4%, 97.7%, 98.6% and 98.7%, respectively, and they also significantly increased as the mass size increased (P = 0.03). Multivariate analysis showed that pancreatic mass size was associated with diagnostic accuracy. The adverse event rates were not significantly different among the five groups. CONCLUSIONS The sensitivities and diagnostic accuracies of EUS-FNA for solid pancreatic lesions are higher for lesions ≥ 10 mm in size, and they are strongly correlated with mass size.

Abstract
BACKGROUND Management of pancreatic lesions depends on the risk of malignancy, which is primarily determined from the cytologic and radiologic evaluation findings. The Papanicolaou Society of Cytopathology (PSC) published a classification system for reporting pancreaticobiliary cytology. However, the "neoplastic: other" category can be further stratified by high-grade atypia (HGA). Studies on the risk of malignancy using the PSC system have been limited. MATERIALS AND METHODS All patients who had undergone endoscopic ultrasound-guided fine-needle aspiration (FNA) for a pancreatic lesion at Massachusetts General Hospital from January 2016 to December 2016 were prospectively classified. The clinical, radiographic, and endoscopic findings, cytologic and histologic diagnoses, and follow-up data from 334 FNA biopsies from 322 patients were reviewed. The neoplastic: other category was subclassified as low-grade atypia or HGA. The absolute risk of malignancy was determined by the histologic outcome or follow-up of ≥6 months. RESULTS The absolute risk of malignancy was 7.7% for the nondiagnostic category; 1.0% for negative; 28.0% for atypical; 0.0% for neoplastic: benign; 30.3% for neoplastic: other; 90.0% for neoplastic: other with HGA; 100% for suspicious; and 100% for positive. When the neoplastic: other with HGA, suspicious, and positive cytologic diagnoses were considered positive, the sensitivity, specificity, positive predictive value, and negative predictive value for pancreatic FNA biopsy was 92.2%, 98.8%, 98.3%, and 94.3%, respectively. CONCLUSIONS Categories of the PSC system each carry an implied absolute risk of malignancy, increasing from the negative to positive categories. The presence of HGA identifies lesions at the greatest risk of malignancy in the neoplastic: other category, and its inclusion with suspicious and positive as positive diagnoses optimizes the diagnostic performance of identifying high-risk lesions that warrant surgical excision.

Abstract
Endoscopic ultrasound (EUS) is now well established as an important tool in clinical practice. From purely diagnostic imaging, it has progressed to include tissue acquisition, which provided the basis for therapeutic procedures. Even as interventional EUS developed, there has been ongoing progress in EUS diagnostic capabilities due to improved imaging systems, better needles for tissue acquisition and development of enhanced imaging functions such as contrast harmonic EUS (CHEUS) and EUS elastography. EUS is well established for differentiation of subepithelial lesions, for T-staging of luminal gastrointestinal and pancreaticobiliary malignancies, for differentiation of benign pancreaticobiliary disorders and for diagnostic tissue acquisition, which can be achieved by EUS-guided fine needle aspiration or by EUS-guided fine needle biopsy using dedicated biopsy needles. This review briefly describes the technique of performing EUS and then discusses its clinical utility in terms of gastrointestinal cancer staging, the evaluation of pancreaticobiliary disorders and tissue acquisition. Enhanced imaging techniques such as CHEUS and EUS elastography are briefly reviewed.

Abstract
BACKGROUND Contrast enhanced harmonic endoscopic ultrasound (CEH-EUS) is a spreading technique; some studies have shown its value in the diagnosis of pancreatic adenocarcinoma using quantitative analysis.
AIM To examine the value of CEH-EUS for differentiating various pancreatic lesions in everyday routine with qualitative and quantitative analysis.
METHODS Data of 55 patients with pancreatic lesions who underwent CEH-EUS were analysed retrospectively. Perfusion characteristics were classified by the investigator qualitatively immediately upon investigation, quantitative analysis was performed later on. Samples from fine needle aspiration (EUS-FNA) or surgical specimen served as gold standard.
RESULTS CEH-EUS showed 39 hypoenhanced lesions, 3 non-enhanced and 13 hyperenhanced lesions. Concordance of the investigators qualitative classification of peak contrast enhancement with quantitative analysis later on was 100%, while other parameters such as arrival time, time to peak or area under the curve did not show additional value. 34 of 39 hypoenhanced lesions were pancreatic adenocarcinoma; of the hyperenhanced lesions 4 were inflammatory, 3 neuroendocrine carcinomas, 1 lymphoma, 1 insulinoma and 4 metastases (2 of renal cell carcinoma, 2 of lung cancer). Non-enhanced lesions showed up as necroses. Sensitivity for the detection of pancreatic adenocarcinoma was 100%, specificity 87.2% for hypoenhancement alone; in otherwise healthy pancreatic tissue all hypoenhanced lesions were pancreatic adenocarcinoma (sensitivity and specificity 100%, PPV and NPV for adenocarcinoma 100%).
CONCLUSION This study again shows the excellent value of CEH-EUS in everyday routine for diagnostics of various focal pancreatic lesions suggesting that qualitatively assessed hypoenhancement is highly predictive for adenocarcinoma. Additional quantitative analysis of perfusion parameters does not add diagnostic yield. In case of the various hyperenhanced pancreatic lesions in our data set, histologic sampling is essential for further treatment.

Abstract
Background and Objectives A needle with Franseen geometry for fine needle aspiration is now available. However, no reports have described prospective evaluations of the Franseen needle or comparisons with the standard needle. The aim of this comparative prospective study was to evaluate the histological diagnostic yield of the Franseen needle and the standard needle using tissue obtained by a single pass of each for the same lesion. Patients and Methods In this study, only tissue obtained by the first pass using the Franseen needle was used. As a comparison group, only tissue obtained from the same lesion by a second pass using the standard needle was used. Evaluation of the histological diagnostic yield of the needles was based on tissue obtained by each single pass with no additional passes. Results A total of 56 patients were prospectively enrolled. The rate of adequate tissue obtained was significantly higher for the Franseen needle than for the standard needle (89.4% vs. 62.5%, respectively; P < 0.05). The sensitivity and accuracy of the Franseen needle were 80.7%, and 84.6%, respectively, while those for the standard needle were 59.6% and 63.5%, respectively. Conclusions The Franseen needle offers a better rate of obtaining adequate tissue and higher diagnostic accuracy than the standard needle.

Slow-Pull Using a Fanning Technique Is More Useful Than the Standard Suction Technique in EUS-Guided Fine Needle Aspiration in Pancreatic Masses. Gut Liver 2018; 12:360-366. [PMID: 29409303 PMCID: PMC5945268 DOI: 10.5009/gnl17140] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2017] [Revised: 09/09/2017] [Accepted: 09/20/2017] [Indexed: 12/21/2022] Open
Abstract
Background/Aims Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for obtaining pancreatic mass samples. The combination of modified techniques (i.e., slow-pull technique and fanning technique) may improve the quality of the sample obtained by EUS-FNA. We investigated the effectiveness of a combined slow-pull fanning technique in EUS-FNA for pancreatic mass. Methods This prospective comparative study investigated EUS-FNA performed for pancreatic solid masses between August 2015 and July 2016. Pairwise specimens were alternately obtained using the following two techniques for targeted pancreatic lesions: standard suction or slow-pull with fanning. We compared the specimen quality, blood contamination, and diagnostic accuracy of these techniques. Results Forty-eight consecutive patients were included (29 men; mean age, 68.1±11.9 years), and 96 pancreatic mass specimens were obtained. The slow-pull with fanning technique had a significantly superior diagnostic accuracy than the suction technique (88% vs 71%, p=0.044). Furthermore, blood contamination was significantly reduced using the slow-pull with fanning technique (ratio of no or slight contamination, 77% vs 56%, p=0.041). No difference was observed in the acquisition of adequate cellularity between the groups. In the subgroup analysis, the tumor size and sampling technique were related to the EUS-FNA diagnostic accuracy. Conclusions The slow-pull with needle fanning technique showed a good diagnostic yield for EUS-FNA for pancreatic mass. This technique can be useful for performing EUS-guided sampling for diagnosing pancreatic disease.

Abstract
INTRODUCTION Indeterminate "atypical" or "suspicious for malignancy" diagnoses in the evaluation of pancreatic fine-needle aspiration (FNA) specimens can present challenges in the clinical management of patients with pancreatic masses. A main goal of this study was to identify, via survey, potential differences in perception between cytologists and clinicians with regard to the implications of, and factors contributing to, indeterminate diagnoses. We also evaluated clinical practice at our institution as it relates to such diagnoses and identified clinicopathologic features associated with indeterminate diagnoses, which allowed for correlation with survey results. MATERIALS AND METHODS Online surveys were sent to cytologists and clinicians to gather information on the respondents' experiences with pancreatic endoscopic ultrasound-guided FNA and their perceptions about the indeterminate diagnostic categories. Cytological specimens and patient medical records were reviewed to collect data on specimen acquisition, cytological features, tumor characteristics, and patient management. RESULTS Survey responses revealed that cytologists and clinicians held similar perceptions of the clinical impact of the indeterminate categories but had dissimilar ideas on the factors contributing to these diagnoses. Statistically significant associations were identified between indeterminate diagnoses and the following variables: number of passes performed; adequacy on rapid on-site evaluation; repeat FNA procedures; lesions with cystic changes; and well-differentiated tumor cytomorphology. CONCLUSIONS Awareness of the perceptions of cytologists and clinicians about, as well as the clinical features and cytologic variables associated with, "indeterminate" cases has the potential to improve patient care.

Abstract
Tissue acquisition using EUS has considerably evolved since the first EUS-FNA was reported 25 years ago. Its introduction was an important breakthrough in the endoscopic field. EUS-FNA has now become a part of the diagnostic and staging algorithm for the evaluation of benign and malignant diseases of the gastrointestinal tract and of the organs in its proximity, including lung diseases. This review aims to present the history of EUS-FNA development and to provide a perspective on the recent developments in procedural techniques and needle technologies that have significantly extended the role of EUS and its clinical applications. There is a bright future ahead for EUS-FNA in the years to come as extensive research is conducted in this field and various technologies are continuously implemented into clinical practice.

Abstract
Background/Aims The superiority of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) over EUS-guided fine needle aspiration (EUS-FNA) remains controversial. Given the lack of studies analyzing histologic specimens acquired from EUS-FNB or EUS-FNA, we compared the proportion of the histologic core obtained from both techniques. Methods A total of 58 consecutive patients with solid mass lesions were enrolled and randomly assigned to the EUS-FNA or EUS-FNB groups. The opposite needle was used after the failure of core tissue acquisition using the initial needle with up to three passes. Using computerized analyses of the scanned histologic slide, the overall area and the area of the histologic core portion in specimens obtained by the two techniques were compared. Results No significant differences were identified between the two groups with respect to demographic and clinical characteristics. Fewer needle passes were required to obtain core specimens in the FNB group (p<0.001). There were no differences in the proportion of histologic core (11.8%±19.5% vs 8.0%±11.1%, p=0.376) or in the diagnostic accuracy (80.6% vs 81.5%, p=0.935) between two groups. Conclusions The proportion of histologic core and the diagnostic accuracy were comparable between the FNB and FNA groups. However, fewer needle passes were required to establish an accurate diagnosis in EUS-FNB.

Abstract
OBJECTIVES Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely performed for the evaluation of pancreatic masses. We evaluated the performance characteristics of EUS-FNA in obtaining a diagnosis of pancreatic malignancy. METHODS We performed a multicenter study of patients who underwent EUS-FNA for a solid pancreatic mass. Endoscopic ultrasound-guided FNA was standardized using a 25-gauge needle, slow-pull stylet technique for specimen acquisition, and on-site cytopathology. For the primary analysis, only malignant cytology was regarded as positive. A secondary analysis was performed in which malignant and/or suspicious cytology was regarded as positive. RESULTS A total of 138 patients underwent EUS-FNA. In the primary analysis, the sensitivity of EUS-FNA for malignancy was 56.7% on first pass, 73.3% on second pass, 83.3% on third pass, 89.2% on fourth pass, and 90.8% on fifth pass, with no increase beyond the fifth pass. In the secondary analysis, the sensitivity was 75.0% on first pass, 89.2% on second pass, 93.3% on third pass, and 95.8% on fourth pass, with no increase beyond the fourth pass. No significant relationship was seen between lesion size and diagnostic yield. CONCLUSIONS Using a 25-gauge needle, the maximal diagnostic yield of EUS-FNA for a solid pancreatic mass is reached after 4 needle passes.

Abstract
Background Several suction techniques have been developed recently to enhance tissue acquisition when sampling solid lesions using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The aim of this study is to determine whether a new modified wet suction technique (MWST) compared with the conventional dry suction technique (DRST) shall present better outcomes with respect to diagnostic yield and specimen quality of solid lesions in the intra-abdomen and mediastinum. Methods/design This is a single-blind, randomized, controlled, superiority trial conducted at four large tertiary care centers in China. Two hundred and ninety-six patients with solid lesions referred for EUS-FNA will be randomly assigned to group A, using DRST for the first pass, or group B, using MWST for the first pass in a ratio of 1:1. Following a 2 × 2 cross-over design, the pass sequence for group A is DRST, MWST, DRST, MWST. For group B, the pass sequence is MWST, DRST, MWST, DRST. All procedures will be performed by experienced echoendoscopists, and the patients and assessors (cytologists and pathologists) will be blinded during the entire study. The primary outcome measure is the diagnosis yield. Secondary outcome measures are specimen quality, including assessment of quantity of cell, tissue integrity, and blood contamination. Discussion To our knowledge, this is the first large-scale randomized controlled trial to compare MWST with DRST when sampling solid lesions in the intra-abdomen and mediastinum. The results may contribute to future multicenter clinical trials in standardizing suction techniques during EUS-FNA. Trial registration Clinical Trials.gov, NCT02789371.

Abstract
Background and Objectives: The ability to obtain adequate tissue of solid pancreatic lesions by EUS-guided remains a challenge. The aim of this study was to compare the performance characteristics and safety of EUS-FNA for evaluating solid pancreatic lesions using the standard 22-gauge needle versus a novel EUS biopsy needle. Methods: This was a multicenter retrospective study of EUS-guided sampling of solid pancreatic lesions between 2009 and 2015. Patients underwent EUS-guided sampling with a 22-gauge SharkCore (SC) needle or a standard 22-gauge FNA needle. Technical success, performance characteristics of EUS-FNA, the number of needle passes required to obtain a diagnosis, diagnostic accuracy, and complications were compared. Results: A total of 1088 patients (mean age = 66 years; 49% female) with pancreatic masses underwent EUS-guided sampling with a 22-gauge SC needle (n = 115) or a standard 22-gauge FNA needle (n = 973). Technical success was 100%. The frequency of obtaining an adequate cytology by EUS-FNA was similar when using the SC and the standard needle (94.1% vs. 92.7%, respectively). The sensitivity, specificity, and diagnostic accuracy of EUS-FNA for tissue diagnosis were not significantly different between two needles. Adequate sample collection leading to a definite diagnosis was achieved by the 1st, 2nd, and 3rd pass in 73%, 92%, and 98% of procedures using the SC needle and 20%, 37%, and 94% procedures using the standard needle (P < 0.001), respectively. The median number of passes to obtain a tissue diagnosis using the SC needle was significantly less as compared to the standard needle (1 and 3, respectively; P < 0.001). Conclusions: The EUS SC biopsy needle is safe and technically feasible for EUS-FNA of solid pancreatic mass lesions. Preliminary results suggest that the SC needle has a diagnostic yield similar to the standard EUS needle and significantly reduces the number of needle passes required to obtain a tissue diagnosis.

Abstract
Background and Objectives With improvements in imaging technologies, pancreatic cystic lesions (PCLs) have been increasingly identified in recent years. However, the imaging modalities used to differentiate the categories of pancreatic cysts remain limited, which may cause confusion when planning treatment. Due to progress in endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) technology, auxiliary diagnosis by the detection of cystic fluid has become a recent trend. Methods From March 2015 to April 2016, 120 patients with PCLs were enrolled in this study. According to the results of EUS, cyst fluid carcinoembryonic antigen (CEA) analysis, and cystic fluid cytology, the patients were divided into two groups: a nonmucinous and a mucinous group. Of those, 61 patients who had undergone surgical resection were included in the analysis. The clinical features, biochemical and tumor markers of cyst fluid as well as the cytological test results of the patients were compared with histopathology results. Results A cyst size of 4.0 cm was used as the boundary value; a cyst ≤4.0 cm was defined as a small PCL. 87 (72.5%) lesions were ≤4.0 cm, and 33 (27.5%) lesions were >4.0 cm. Regarding the analysis of CEA and carbohydrate antigens 19-9 (CA19-9), significant differences were found between the nonmucinous and mucinous groups (P < 0.05) according to nonparametric independent samples tests. The EUS, cystic fluid CEA, and cystic fluid cytology results were compared with the tissue pathology findings using McNemar's test (P < 0.05) and showed a sensitivity of 90% and a specificity of 84%. Conclusion A diagnostic combination of EUS, cyst fluid CEA, and cystic fluid cytology could be used to differentiate small pancreatic cystic neoplasms. Cystic fluid cytology analysis is helpful for planning treatment for pancreatic cystic tumors that pose a surgical risk.

Abstract
Autoimmune pancreatitis (AIP) is increasingly being recognized due to improved understanding of the disease and its criteria for diagnosis. The classic type 1 AIP can be diagnosed on clinical data, but type 2 AIP requires histologic confirmation. Current criteria incorporate cross-sectional imaging and endoscopic retrograde cholangiopancreatography in the diagnosis of AIP. However, endoscopic ultrasound (EUS) will likely have an increasing role in the diagnosis through its characteristic imaging, image-enhancing techniques, and its ability to acquire tissue through either fine needle aspiration or biopsy. This article will review the diagnostic challenges of AIP and the current role of EUS.

Comparison of cytological and histological preparations in the diagnosis of pancreatic malignancies using endoscopic ultrasound-guided fine needle aspiration. Hepatobiliary Pancreat Dis Int 2017; 16:418-423. [PMID: 28823373 DOI: 10.1016/s1499-3872(17)60035-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2016] [Accepted: 03/15/2017] [Indexed: 02/05/2023]
Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has become a crucial diagnostic technique for pancreatic malignancies. The specimen obtained by EUS-FNA can be prepared for either cytological or histological examinations. This study was to compare diagnostic performance of cytological and histological preparations using EUS-FNA in the same lesions when pancreatic malignancies were suspected. METHODS One hundred and eighteen patients who underwent EUS-FNA for suspected pancreatic malignancies were consecutively enrolled. All procedures were conducted by a single echoendoscopist under the same conditions. Four adequate preparations were obtained by 22-gauge needles with 20 to-and-fro movements for each pass. The 4 preparations included 2 cytological and 2 histological specimens. The pathologic reviews of all specimens were conducted independently by a single experienced cytopathologist. Sensitivity, specificity, and accuracy of the 2 preparations were compared. RESULTS The enrolled patients consisted of 62 males (52.5%), with the mean age of 64.6±10.5 years. Surgery was performed in 23 (19.5%) patients. One hundred and sixteen (98.3%) lesions were classified as malignant, while 2 (1.7%) were benign. Sensitivity of cytology and histology were 87.9% and 81.9%, respectively, with no significant difference (P=0.190). Accuracy was also not significantly different. Cytological preparation was more sensitive when the size of lesion was <3 cm (86.7% vs 68.9%, P=0.033). CONCLUSIONS Our results suggested that the diagnostic performances of cytological and histological preparations are not significantly different for the diagnosis of pancreatic malignancies. However, cytological preparation might be more sensitive for pancreatic lesions <3 cm.

Increasing Number of Passes Beyond 4 Does Not Increase Sensitivity of Detection of Pancreatic Malignancy by Endoscopic Ultrasound-Guided Fine-Needle Aspiration. Clin Gastroenterol Hepatol 2017; 15:1071-1078.e2. [PMID: 28025154 DOI: 10.1016/j.cgh.2016.12.018] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2016] [Revised: 12/10/2016] [Accepted: 12/12/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS It is not clear exactly how many passes are required to determine whether pancreatic masses are malignant using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). We aimed to define the per-pass diagnostic yield of EUS-FNA for establishing the malignancy of a pancreatic mass, and identify factors associated with detection of malignancies. METHODS In a prospective study, 239 patients with solid pancreatic masses were randomly assigned to groups that underwent EUS-FNA, with the number of passes determined by an on-site cytopathology evaluation or set at 7 passes, at 3 tertiary referral centers. A final diagnosis of pancreatic malignancy was made based on findings from cytology, surgery, or a follow-up evaluation at least 1 year after EUS-FNA. The cumulative sensitivity of detection of malignancy by EUS-FNA was calculated after each pass; in the primary analysis, lesions categorized as malignant or suspicious were considered as positive findings. RESULTS Pancreatic malignancies were found in 202 patients (84.5% of the study population). EUS-FNA detected malignancies with 96% sensitivity (95% confidence interval [CI], 92%-98%); 4 passes of EUS-FNA detected malignancies with 92% sensitivity (95% CI, 87%-95%). Tumor size greater than 2 cm was the only variable associated with positive results from cytology analysis (odds ratio, 7.8; 95% CI, 1.9-31.6). In masses larger than 2 cm, 4 passes of EUS-FNA detected malignancies with 93% sensitivity (95% CI, 89%-96%) and in masses ≤2 cm, 6 passes was associated with 82% sensitivity (95% CI, 61%-93%). Sensitivity of detection did not increase with increasing number of passes. CONCLUSIONS In a prospective study, we found 4 passes of EUS-FNA to be sufficient to detect malignant pancreatic masses; increasing the number of passes did not increase the sensitivity of detection. Tumor size greater than 2 cm was associated with malignancy, and a greater number of passes may be required to evaluate masses 2 cm or less. ClinicalTrials.gov number, NCT01386931.

Abstract
PURPOSE To determine the accuracy and safety of the percutaneous biopsy of pancreatic mass lesions. MATERIALS AND METHODS Over a 12-year period clinical parameters, imaging, pathologic results, and complications were assessed in patients undergoing percutaneous biopsies pancreatic lesions. RESULTS One hundred fifty-three patients underwent pancreatic biopsy. The preferred modality for performing the biopsy was ultrasound (93%, n=143) followed by computerized tomography (7%, n=10). Histologic diagnosis was achieved in 147 patients, of which 3 (2%) were benign and 144 (94%) were malignant. Complications included a single death from overwhelming hemorrhage and 2 patients with morbidity (hematoma and cerebrovascular accident). The sensitivity and specificity of percutaneous biopsies was 90% and 95%, respectively. CONCLUSIONS Ultrasound-guided and computerized tomographic-guided percutaneous biopsy of pancreatic lesions is an effective and safe method to confirm or refute malignancy in suspicious pancreatic lesions. Endoscopic ultrasound-guided Tru-Cut may have the added advantage of avoiding the risk of peritoneal soiling.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) is used for pancreatic adenocarcinoma staging and obtaining a tissue diagnosis. The objective was to determine patterns of preoperative EUS and the impact on downstream treatment. METHODS The Surveillance, Epidemiology, and End Results (SEER) Medicare-linked database was used to identify patients with pancreatic adenocarcinoma. The staging period was the first staging procedure within 6 months of surgery until surgery. Logistic regression was used to determine factors associated with preoperative EUS. The main outcome was EUS in the staging period, with secondary outcomes including number of staging tests and time to surgery. RESULTS 2782 patients were included, 56% were treated at an academic hospital (n = 1563). 1204 patients underwent EUS (43.3%). The factors most associated with receipt of EUS were: earlier year of diagnosis, SEER area, and a NCI or academic hospital (all p < 0.0001). EUS was associated with a longer time to surgery (17.8 days; p < 0.0001), and a higher number of staging tests (40 tests/100 patients; p < 0.0001). CONCLUSIONS Factors most associated with receipt of EUS are geographic, temporal, and institutional, rather than clinical/disease factors. EUS is associated with a longer time to surgery and more preoperative testing, and additional study is needed to determine if EUS is overused.

Comparison of the diagnostic performance of 2 core biopsy needles for EUS-guided tissue acquisition from solid pancreatic lesions. Gastrointest Endosc 2017; 85:1017-1024.

Abstract
BACKGROUND AND AIMS A new core biopsy needle with a novel tip, opposing bevel, and sheath design has recently been introduced for EUS-guided fine-needle biopsy (FNB). The diagnostic utility of this needle for differentiating solid pancreatic masses is currently unknown. The aim of this study was to compare the diagnostic performance and yield for tissue acquisition from solid pancreatic lesions of the opposing bevel needle with those of a reverse bevel EUS-FNB needle. METHODS Consecutive patients with solid pancreatic masses undergoing EUS-FNB using the opposing bevel (n = 101) and the reverse bevel (n = 100) core biopsy needles were included in the study. Final diagnosis was based on positive histology or at least 12 months of follow-up in cases with a negative biopsy. The primary outcome was the diagnostic performance of the 2 needles for malignant pancreatic masses. A secondary outcome was the diagnostic yield. RESULTS Compared with the reverse bevel needle, using strict criteria the opposing bevel needle provided significantly higher sensitivity (71.1% vs 90.1%; P = .0006) and overall accuracy (74% vs 92%; I = 0.0006) for discriminating malignant from benign solid pancreatic masses. The proportion of samples classified as adequate for histologic analysis was 87% for the reverse bevel needle versus 99% for the opposing bevel needle (p = 0.002) Multivariate analysis controlling the needle gauge and site did not show any significant difference in accuracy and sensitivity between the 2 groups. There were no adverse events in either group. CONCLUSIONS In this first, large, single-center preliminary cohort study, an EUS core biopsy needle with a novel tip, opposing bevel, and sheath design afforded substantially superior tissue yield and diagnostic performance compared with a reverse-bevel needle. If replicated by randomized controlled trials, our findings suggest that similarly designed needles could become the standard of care for EUS-guided tissue acquisition from solid pancreatic masses.

KRAS mutation testing on all non-malignant diagnosis of pancreatic endoscopic ultrasound-guided fine-needle aspiration biopsies improves diagnostic accuracy. Pathology 2017; 49:379-386. [PMID: 28450086 DOI: 10.1016/j.pathol.2016.12.348] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2016] [Revised: 12/09/2016] [Accepted: 12/20/2016] [Indexed: 02/09/2023]
Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the procedure of choice for the cytologic diagnosis of pancreatic masses. The specificity of EUS-FNA approaches 100%, but the sensitivity is still low, and the high rate of indeterminate (atypical and suspicious) and false-negative results needs improvement. KRAS gene is frequently mutated in pancreatic ductal adenocarcinoma (PDAC) (up to 90%), and mutation analysis of KRAS has been proposed as diagnostic biomarker of PDAC. In most laboratories, KRAS mutation testing is performed by Sanger sequencing or real time-quantitative polymerase chain reaction (RT-qPCR), but these methods may give false-negative results in routine samples, mainly due to low cellularity. In order to increase the sensitivity of EUS-FNA, we propose a sequential approach for detecting KRAS mutations using mutant enriched-PCR (ME-PCR, sensitivity up to 0.1%) in cytologically indeterminate and negative samples tested wild-type by RT-qPCR. EUS-FNA specimens from 107 patients with pancreatic masses (51 males, 56 females, mean age 67 years) were cytologically examined. According to the Papanicolaou Society of Cytopathology guidelines, 50 cases (47%) were classified malignant, 15 (14%) suspicious, 13 (12%) atypical and 10 (9%) negative for malignancy; 18 cases (17%) were non-diagnostic. The overall specificity and sensitivity of cytological examination were 100% and 61%, respectively, when only negative and positive cases were considered; when atypical and suspicious were added to positive cases, the sensitivity increased to 95.1% and the specificity decreased to 85.7%. In all the cases, DNA was extracted from the cell-block and KRAS mutations were investigated by RT-qPCR, followed by ME-PCR in non-amplifiable and negative cases. The overall sensitivity and specificity of KRAS mutation testing alone were 79.3% and 100%; when KRAS mutation testing was performed in indeterminate and negative cytology, the sensitivity increased to 90% with specificity to 100%. Our data indicate that conventional cytology from EUS-FNA samples is highly specific for the diagnosis of pancreatic cancer. Indeterminate and negative cases need to be screened for KRAS mutations; this two-step approach may greatly improve the diagnostic accuracy of this method.

Abstract
Endoscopic ultrasound (EUS) has been increasingly used for the diagnosis and staging of pancreatic cancer. It has recently become the modality of choice in assessing pancreatic lesions overcoming other traditional modalities. Typically lesions located at the tail of the pancreas are best accessed through the stomach. We present a patient with pancreatic tail mass occurring in the setting of a large hiatal hernia, intrathoracic stomach, and severe lumbar levoscoliosis. Due to altered anatomy and extensive vascular connections of the mass, any surgical or radiological intervention was considered high risk for the patient. EUS was the only modality capable of providing a pancreatic mass tissue sample in this patient with challenging thoraco-abdominal anatomy. Moreover, pancreatic tail lesions are traditionally best accessed through the gastric fundus; however, in view of the patient's altered anatomy, EUS-fine needle aspiration (FNA) had to be performed through the duodenum. This case raises the importance of EUS when surgical and radiological interventions are restricted.
