Chow CW, Haider SA, Ragunath K, Aithal GP, James MW, Ortiz-Fernandez-Sordo J, Aravinthan AD, Venkatachalapathy SV. Comparison of the reverse bevel versus Franseen type endoscopic ultrasound needle. World J Gastrointest Endosc 2020; 12:266-275. [PMID: 32994857 PMCID: PMC7503614 DOI: 10.4253/wjge.v12.i9.266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 06/08/2020] [Accepted: 08/01/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Reverse bevel (RB) needle is widely used for endoscopic ultrasound fine needle biopsy (EUS-FNB). A 3-plane symmetrical needle with Franseen geometry (FG) has recently become available.
AIM To compare the clinical efficacy of FG to that of RB needle.
METHODS A retrospective cohort study of all adult patients who underwent EUS-FNB for solid and mixed lesions either with 22G RB needle or 22G FG needle between January 2016 and February 2019 was undertaken. All cytology slides were reviewed by an independent gastrointestinal cytopathologist blinded to the needle used and the initial cytology report. The primary and secondary outcomes were to assess the sample adequacy using Euro-cytology criteria and the number of cell clusters, respectively.
RESULTS Two hundred and twenty six procedures were included in the study. RB needle was used in 128 procedures and FG needle in 98 procedures. The baseline characteristics of both groups were comparable. On multivariable analysis, FG needle (P = 0.02) and location of the lesion (P < 0.01) were independently associated with adequate tissue. Further, the use of FG needle (P = 0.04) and the size of the lesion (P = 0.02) were independently associated with acquisition of increased number of cell clusters.
CONCLUSION FG needle is superior to RB needle in acquiring adequate tissue and attaining higher number of cell clusters for solid and mixed lesions.

Abstract
Over the last decade, impressive technological advances have occurred in ultrasonography and small-bowel endoscopy. Nowadays, endoscopic ultrasonography is an essential diagnostic tool and a therapeutic weapon for pancreatobiliary disorders. Capsule endoscopy and device-assisted enteroscopy have quickly become the reference standard for the diagnosis of small-bowel luminal diseases, thereby leading to radical changes in diagnostic and therapeutic pathways. We herein provide an up-to-date overview of the latest advances in endoscopic ultrasonography and small-bowel endoscopy, focusing on the emerging paradigms and technological innovations that might improve clinical practice in the near future.

Abstract
BACKGROUND AND OBJECTIVE EUS-guided fine-needle biopsy has become the standard for tissue sampling. A new 20G ProCore™ (PC) needle has been developed to overcome the limitations of tissue acquisition of the smaller needles (22G, 25G) and the rigidity of the larger one (19G). The aim of this study is to assess the performance of the 20G PC needle. MATERIALS AND METHODS Patients who underwent EUS-guided tissue acquisition with the 20G PC needle of pancreatic and extra-pancreatic mass lesions were retrospectively identified at three Italian centers (Bologna, Fermo, and Palermo). Diagnostic adequacy, accuracy, and tissue core acquisition were the outcome measures. All the cases were performed without rapid on-site evaluation. RESULTS A total of 384 patients with pancreatic (62.2%) and extra-pancreatic lesions were included in the study. For pancreatic lesions, adequacy, accuracy, sensitivity, and specificity were 92.4%, 91.5%, 90.8%, and 100%, respectively, with a number needed to misdiagnose (NNM) of 11.8. The tissue core was obtained in 72% of cases. Transduodenal approach was performed in 150 pancreatic lesions; adequacy, accuracy, and tissue core acquisition were 88.7%, 90%, and 66%, respectively (NNM 10). For extrapancreatic lesions, adequacy, accuracy, sensitivity, specificity, and tissue core sampling were 95.3%, 95.3%, 92.6%, 100%, and 84.5% (NNM 21.3). CONCLUSIONS The 20G PC needle showed high diagnostic adequacy and accuracy, regardless the access route.

Transhepatic forceps biopsy combined with biliary drainage in obstructive jaundice: safety and accuracy. Eur Radiol 2018; 29:2426-2435. [PMID: 30511177 DOI: 10.1007/s00330-018-5852-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 10/03/2018] [Accepted: 10/23/2018] [Indexed: 12/11/2022]
Abstract
PURPOSE This study was conducted in order to investigate the safety and accuracy of percutaneous transluminal forceps biopsy (PTFB) during percutaneous biliary drainage (PTBD) in patients with a suspicion of malignant biliary stricture. MATERIAL AND METHODS Fifty consecutive patients with obstructive jaundice underwent PTFB during PTBD. Biopsy specimens were obtained using 5.2-F flexible biopsy forceps and these specimens were independently analysed by two pathologists. Consensus was obtained in case of discrepancy. Biopsy was considered as a true positive when tumour cells were retrieved. In the absence of tumour cells, comparison with available surgical findings and/or endoscopic ultrasound fine-needle aspiration (EUS-FNA) and/or percutaneous liver biopsy and/or imaging or clinical follow-up was made to distinguish true and false negatives. Specificity, sensitivity, positive predictive value, negative predictive value and accuracy were calculated. Influence of tumour location and pre-operative imaging findings was evaluated. Adverse events were reported. RESULTS Biliary drainage and tissue sampling were achieved in 100% of patients. Sensitivity and specificity were 70 and 100%, respectively, while overall accuracy was 72%. After excluding the first 25 patients, accuracy and sensitivity for tissue sampling reached 80 and 78%, respectively. Sensitivity was better (87%) if stenosis was located at the upper part of the biliary tree, compared to the lower part (55%). In case of cholangiocarcinoma or intraductal invasion suspected on imaging, biopsy was contributive in 84 and 81% of patients, respectively. Four complications occurred consisting of one bile leak, two haemobilia and one pneumoperitoneum. CONCLUSION PTFB combined with PTBD is a safe and effective technique for both histopathological diagnosis and biliary decompression of biliary strictures. KEY POINTS Implications for patient care: • Percutaneous transbiliary forceps biopsy is technically feasible (100% of tissue sampling in our study) and is a safe technique. • Radiological management combining PTFB plus PTBD may allow diagnosis and treatment of the biliary stricture at the same time. • Sensitivity and accuracy for PTFB reached 78 and 80%, respectively, with a 100% specificity.

A meta-analysis of endoscopic ultrasound-fine-needle aspiration compared to endoscopic ultrasound-fine-needle biopsy: diagnostic yield and the value of onsite cytopathological assessment. Endosc Int Open 2017; 5:E363-E375. [PMID: 28497108 PMCID: PMC5425293 DOI: 10.1055/s-0043-101693] [Citation(s) in RCA: 124] [Impact Index Per Article: 17.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/13/2022] Open
Abstract
Background The diagnostic yield of endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) is variable, and partly dependent upon rapid onsite evaluation (ROSE) by a cytopathologist. Second generation fine-needle biopsy (FNB) needles are being increasingly used to obtain core histological tissue samples. Aims Studies comparing the diagnostic yield of EUS guided FNA versus FNB have reached conflicting conclusions. We therefore conducted a systematic review and meta-analysis to compare the diagnostic yield of FNA with FNB, and specifically evaluating the diagnostic value of ROSE while comparing the two types of needles. Methods We searched several databases from inception to 10 April 2016 to identify studies comparing diagnostic yield of second generation FNB needles with standard FNA needles. Risk ratios (RR) were calculated for categorical outcomes of interest (diagnostic adequacy, diagnostic accuracy, and optimal quality histological cores obtained). Standard mean difference (SMD) was calculated for continuous variables (number of passes required for diagnosis). These were pooled using random effects model of meta-analysis to account for heterogeneity. Meta-regression was conducted to evaluate the effect of ROSE on various outcomes of interest. Results Fifteen studies with a total of 1024 patients were included in the analysis. We found no significant difference in diagnostic adequacy [RR 0.98 (0.91, 1.06), (I2 = 51 %)]. Although not statistically significant (P = 0.06), by meta-regression, in the absence of ROSE, FNB showed a relatively better diagnostic adequacy. For solid pancreatic lesions only, there was no difference in diagnostic adequacy [RR 0.96 (0.86, 1.09), (I2 = 66 %)]. By meta-regression, in the absence of ROSE, FNB was associated with better diagnostic adequacy (P = 0.02). There was no difference in diagnostic accuracy [RR 0.99 (0.95, 1.03), (I2 = 27 %)] or optimal quality core histological sample procurement [RR 0.97 (0.89, 1.05), (I2 = 9.6 %)]. However, FNB established diagnosis with fewer passes [SMD 0.93 (0.45, 1.42), (I2 = 84 %)]. The absence of ROSE was associated with a higher SMD, i. e., in the presence of an onsite pathologist, FNA required relatively fewer passes to establish the diagnosis than in the absence of an onsite pathologist. Conclusions There is no significant difference in the diagnostic yield between FNA and FNB, when FNA is accompanied by ROSE. However, in the absence of ROSE, FNB is associated with a relatively better diagnostic adequacy in solid pancreatic lesions. Also, FNB requires fewer passes to establish the diagnosis.

Abstract
BACKGROUND AND AIM There are currently no data regarding the number and type of endoscopic ultrasound (EUS) procedures being carried out in the USA. The aims of the present study are to: (i) estimate the annual number of EUS procedures being carried out in a nationwide database; (ii) describe the indications and types of EUS carried out; and (iii) examine short-term trends in volume. METHODS Retrospective analysis from the Clinical Outcomes Research Initiative (CORI) of EUS procedures carried out on patients >18 years of age from 1 January 2010 through 31 December 2013. RESULTS EUS cases (n = 7614) were carried out by 68 endoscopists at 18 sites over the study period, representing 1.7% of the total number of endoscopic procedures. The most common indications were evaluation of a pancreatic mass (14.7%), diagnostic sampling with fine-needle aspiration (14.1%), and evaluation of a pancreatic cyst (14.0%). The number of EUS examinations and cases undergoing same-day endoscopic retrograde cholangiopancreatography (ERCP) increased over the study period (P < 0.0001). Use of general anesthesia or deep sedation increased markedly from 37.8% to 82.8% of procedures (P < 0.0001). CONCLUSIONS This is the largest survey of EUS practice in the USA. Evaluation of the pancreas accounts for approximately 40% of the indications for EUS. Use of EUS increased over the study period, and the proportion carried out with deep sedation or general anesthesia also increased. These data may have implications regarding the number of endosonographers who should be trained, as well as cost issues pertaining to increasing use of anesthesia providers and same-day ERCP.

Abstract
BACKGROUND AND AIMS The use of contrast-harmonic EUS (CH-EUS) in routine clinical practice is increasing rapidly but is not yet standardized. We present the levels of evidence (LEs) found in the literature to put its clinical outcomes in the appropriate perspective. METHODS We conducted a systematic review of the available English-language articles. The LEs were stratified according to the Oxford Centre for Evidence-Based Medicine guidelines. RESULTS Overall, 210 articles were included and presented according to different pathologic conditions. For pancreatic solid neoplasms, the pooled sensitivity and specificity in the diagnosis of pancreatic carcinoma were very high (LE 1); quantitative analysis and guidance of FNA were reported as investigational research (LE 2-3). For pancreatic cystic lesions, the identification of neoplastic solid components as hyperenhanced lesions represented a promising application of CH-EUS (LE 2). For lymph nodes, CH-EUS increased the diagnostic yield of B-mode EUS for the detection of malignancy (LE 2). For submucosal tumors, CH-EUS seemed useful for differential diagnosis and risk stratification (LE 2-3). For other applications, differential diagnosis of gallbladder and vascular abnormalities by CH-EUS were reported (LE 2-3). CONCLUSIONS The LEs of CH-EUS in the literature have evolved from the initial descriptive studies to multicenter and prospective trials, and even meta-analyses. The differential diagnosis between benign and malignant lesions is the main field of application of CH-EUS. With regard to pancreatic solid neoplasms, the concomitant use of both CH-EUS and EUS-FNA may have additive value in increasing the overall accuracy by overcoming the false-negative results associated with each individual technique. Other applications are promising but still investigational.

Abstract
BACKGROUND AND AIMS The ability to safely and effectively obtain sufficient tissue for pathologic evaluation by using endoscopic ultrasound (EUS) guidance remains a challenge. Novel designs in EUS needles may provide for improved ability to obtain such core biopsies. The aim of this study was to evaluate the diagnostic yield of core biopsy specimens obtained using a novel EUS needle specifically designed to obtain core biopsies. PATIENTS AND METHODS Multicenter retrospective review of all EUS-guided fine-needle biopsies obtained using a novel biopsy needle (SharkCore FNB needle, Medtronic, Dublin, Ireland). Data regarding patient demographics, lesion type/location, technical parameters, and diagnostic yield was obtained. RESULTS A total of 250 lesions were biopsied in 226 patients (Median age 66 years; 113 (50 %) male). Median size of all lesions (mm): 26 (2 - 150). Overall, a cytologic diagnosis was rendered in 81 % specimens with a median number of 3 passes. When rapid onsite cytologic evaluation (ROSE) was used, cytologic diagnostic yield was 126/149 (85 %) with a median number of 3 passes; without ROSE, cytologic diagnostic yield was 31/45 (69 %, P = 0.03) with a median number of 3 passes. Overall, a pathologic diagnosis was rendered in 130/147 (88 %) specimens with a median number of 2 passes. Pathologic diagnostic yield for specific lesion types: pancreas 70/81 (86 %), subepithelial lesion 13/15 (87 %), lymph node 26/28 (93 %). Ten patients (10/226, 4 %) experienced adverse events: 4 acute pancreatitis, 5 pain, 1 fever/cholangitis. CONCLUSIONS Initial experience with a novel EUS core biopsy needle demonstrates excellent pathologic diagnostic yield with a minimum number of passes.

Histological diagnosis of gastric submucosal tumors: A pilot study of endoscopic ultrasonography-guided fine-needle aspiration biopsy vs mucosal cutting biopsy. World J Gastrointest Endosc 2015; 7:1142-1149. [PMID: 26468338 PMCID: PMC4600180 DOI: 10.4253/wjge.v7.i14.1142] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2015] [Revised: 06/25/2015] [Accepted: 09/08/2015] [Indexed: 02/05/2023] Open
Abstract
AIM: To compare the usefulness of endoscopic ultrasonography-guided fine-needle aspiration biopsy (EUS-FNAB) without cytology and mucosal cutting biopsy (MCB) in the histological diagnosis of gastric submucosal tumor (SMT).
METHODS: We prospectively compared the diagnostic yield, feasibility, and safety of EUS-FNAB and those of MCB based on endoscopic submucosal dissection. The cases of 20 consecutive patients with gastric SMT ≥ 1 cm in diameter. who underwent both EUS-FNAB and MCB were investigated.
RESULTS: The histological diagnoses were gastrointestinal stromal tumors (n = 7), leiomyoma (n = 6), schwannoma (n = 2), aberrant pancreas (n = 2), and one case each of glomus tumor, metastatic hepatocellular carcinoma, and no-diagnosis. The tumors’ mean size was 23.6 mm. Histological diagnosis was made in 65.0% of the EUS-FNABs and 60.0% of the MCBs, a nonsignificant difference. There were no significant differences in the diagnostic yield concerning the tumor location or tumor size between the two methods. However, diagnostic specimens were significantly more frequently obtained in lesions with intraluminal growth than in those with extraluminal growth by the MCB method (P = 0.01). All four SMTs with extraluminal growth were diagnosed only by EUS-FNAB (P = 0.03). No complications were found in either method.
CONCLUSION: MCB may be chosen as an alternative diagnostic modality in tumors showing the intraluminal growth pattern regardless of tumor size, whereas EUS-FNAB should be performed for SMTs with extraluminal growth.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a useful tool for the diagnosis of suspected abdominal or mediastinal neoplastic lesions. AIM To evaluate the impact of EUS-FNA and multidisciplinary approach on the diagnostic work-up and therapeutic management of patients with abdominal or mediastinal neoplastic lesions. PATIENTS AND METHODS One hundred and twenty patients (69 men, median age 65 years) with a suspected abdominal or mediastinal neoplastic mass at computed tomography or MRI underwent EUS-FNA. All EUS-FNA findings and clinical data were evaluated by a multidisciplinary team (oncologists, surgeons, and gastroenterologists). EUS-FNA findings were compared with the final diagnosis made by histological evaluation of the surgical specimen or clinical outcome at follow-up. RESULTS A correct diagnosis was obtained by EUS-FNA in 96/120 patients (80%), indicating benignancy of the lesion in 21 (18%) cases and confirming malignancy in 75 (62%). On the basis of EUS-FNA findings, chemotherapy was tailored in 57/75 (76%) patients with malignancy whereas the surgical strategy was changed in 21/120 (18%) of patients. Overall, the diagnostic accuracy of EUS-FNA was 85%. A multidisciplinary team approach enabled a correct diagnosis in patients in whom EUS-FNA was nondiagnostic and to identify five cases with false-negative EUS-FNA findings. CONCLUSION EUS-FNA has a relevant impact on the management of suspected abdominal or mediastinal neoplastic lesions. A multidisciplinary team approach enables to overcome the EUS-FNA methodological limitations. The combination of EUS-FNA and multidisciplinary team approach could help to diagnose and tailor therapeutic options in such patients.

Abstract
BACKGROUND Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) with bedside cytopathology is the gold standard for assessment of pancreatic, subepithelial, and other lesions in close proximity to the gastrointestinal tract, but it is time-consuming, has certain diagnostic limitations, and bedside cytopathology is not widely available. AIMS The goal of this study is to compare the diagnostic yield of EUS-guided FNA with on-site cytopathology and EUS-guided core biopsy. METHODS Twenty-six patients with gastrointestinal mass lesions requiring biopsy at a tertiary medical center were included in this retrospective analysis of a prospective cohort. Two core biopsies were taken using a 22 gauge needle followed by FNA guided by a bedside cytopathologist at the same endoscopic session. The diagnostic yield and test characteristics of EUS core biopsy and EUS FNA with bedside cytopathology were examined. RESULTS The mean number of passes was 3.2 for FNA, and the mean procedure time was 39.4 minutes. The final diagnosis was malignant in 92.3 %. Sensitivity and specificity were 83 % and 100 %, respectively, for FNA, and 91.7 % and 100 %, respectively, for core biopsy. Diagnostic accuracy was 92.3 % for FNA and 84.6 % for core biopsy. The two approaches were in agreement in 88.4 % with a kappa statistic of 0.66 (95 % confidence interval 0.33 - 0.99). CONCLUSIONS An approach using two passes with a core biopsy needle is comparable to the current gold standard of FNA with bedside cytopathology. The performance of two core biopsies is time-efficient and could represent a good alternative to FNA with bedside cytopathology.

Abstract
BACKGROUND Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract with an increasing incidence. AIMS To review the biology, diagnosis and treatment of gastrointestinal stromal tumours. METHODS A PubMed search using the phrases 'Gastrointestinal stromal tumor', 'imatinib', 'c-kit'. RESULTS The diagnosis of GIST is established by histology supplemented by the immunohistochemical marker CD117, which is positive in 95% of cases. The most common site of the tumour is the stomach. Most GIST are benign with 20-30% malignant. Five-year survival for malignant GIST ranges between 35% and 65% and depends primarily on tumour size, mitotic index and location. The malignant behaviour of GIST is best assessed by invasion of adjacent structures and distant metastases. The gold standard for treatment is surgical resection. Imatinib, a tyrosine kinase inhibitor, is the primary therapy for unresectable, recurrent or metastatic disease. CONCLUSIONS Gastrointestinal stromal tumours are rare tumours of the gastrointestinal tract and they vary in presentation. When surgical resection is not achievable, imatinib is the treatment of choice.

Abstract
Background/Aims We evaluated the performance, clinical role, and diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in gastrointestinal intramural lesions. Methods Procedural and pathologic data were reviewed from consecutive patients undergoing EUS-FNA for intramural lesions. Final diagnoses were determined by surgical histopathologic conformation and the diagnosis of malignancy, including clinical follow-up with repeat imaging. Results Forty-six patients (mean age, 47 years; 24 males) underwent EUS-FNA. Lesions were located in the stomach (n=31), esophagus (n=5), and duodenum (n=10). The median lesion size was 2 cm (range, 1 to 20.6). Final diagnoses were obtained in 22 patients (48%). EUS-FNA was diagnostic in 40 patients (87%). The diagnostic accuracy of cytology for differentiating between benign and malignant lesions was 82%; diagnostic error occurred in three patients (6%). The cytologic results influenced clinical judgment in 78% cases. The primary reasons for negative or no clinical impact were false-negative results, misdirected patient management, and inconclusive cytology. Conclusions EUS-FNA exhibited an 87% diagnostic yield for gastrointestinal intramural lesions; the accuracy of cytology for differentiating malignancy was 82%. The limitations of EUS-FNA were primarily because of nondiagnostic sampling (9%) and probable diagnostic error (6%); these factors may influence the clinical role of EUS-FNA.

Abstract
BACKGROUND AND AIMS Endoscopical examination is not always sufficient for the diagnosis of gastrointestinal masses. This study assessed the diagnostic accuracy and safety of ultrasound-guided percutaneous biopsy of gastrointestinal lesions. METHODS This retrospective study evaluated 114 patients who underwent ultrasound-guided biopsy of gastrointestinal masses with a 18G needle. Thirty-two of these patients underwent a 22G fine-needle biopsy for cytology. Histology was compared with a composite standard of reference for diagnosis (i.e. post-surgery histological evaluation in 73 cases and computed tomography or magnetic resonance scan findings, together with a compatible clinical follow-up for at least 24 months, in the remaining 41 cases). Safety was assessed by recording side effects for up to 4h after the procedure. RESULTS Of the 114 lesions evaluated, 112 were malignant (98.2%) and 2 benign (1.8%). Specimens were adequate for histology in all but one case. Specimens were obtained from the stomach (n=38; 33.3%), small bowel (n=36; 31.6%) and colon (n=40; 35.1%). Diagnosis was correct in 113/114 cases (99.1%). Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy were 99.1%, 100%, 100%, 66%, and 99%, respectively. One of the 114 patients (0.9%) bled from a gastric GIST. CONCLUSIONS Ultrasound-guided percutaneous biopsy of gastrointestinal lesions is a valid alternative when diagnosis of a gastrointestinal mass cannot be obtained with an endoscopical procedure.

Abstract
The role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in evaluating lesions adjacent to the upper gastrointestinal tract wall is well established. However, this tool is underused in evaluating rectal and perirectal lesions, possibly due to insufficient experience and underrecognized value of this procedure. In this study, we report our institutional experience with EUS-FNA as a diagnostic and staging tool for rectal and perirectal lesions. A retrospective chart review was performed and a cohort of 38 patients who underwent rectal EUS-FNA (41 specimens) at our institution between January 2002 and July 2012 was retrieved. The cytology diagnoses were compared with the concurrent or follow-up histologic and clinical diagnoses. Among the total 41 cases, rectal EUS-FNA was performed as a diagnostic procedure in 22 (54%) and a staging procedure in 19 (46%) cases. On cytology examination, 18 cases (44%) were diagnosed as malignant; 1 (2%), as atypical/suspicious for malignancy; 3 (7%), as benign neoplastic; 13 (32%), as nonneoplastic; and 6 (15%), as nondiagnostic cases. Concurrent or follow-up histologic diagnoses were available in 20 cases (48%), 19 of them had concordant cytological/histologic findings (10 benign, 9 malignant). One perirectal lymph node with negative cytology diagnosis was found to be positive on histologic examination, probably due to sampling error on cytology. The sensitivity and specificity of EUS-FNA for detecting malignant rectal/perirectal lesions in this study were 91% and 100%, respectively. Endoscopic ultrasound-guided fine needle aspiration is a useful diagnostic tool for rectal/perirectal lesions; it confirms or excludes malignancy for lesions with high or low clinical suspicions. It serves as a reliable staging method to identify patients for proper clinical management.

Abstract
PURPOSE Mediastinal lymphadenopathy (ML) is a cause for concern, especially in patients with previous malignancy. We report our experience with the use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with immunocytochemical stains in patients being evaluated for ML. METHODS Retrospective analysis of patients with ML of unknown origin who underwent EUS-FNA. On-site evaluation was performed by experienced cytologist, and special immunocytochemical stains were requested as indicated. RESULTS A total of 116 patients were included, and a total of 136 mediastinal LN were sampled. Prior malignancy was present in 45%. The most common site of examined lymph node (LN) were subcarinal (76%, 103 LN). The median long and short axis diameters were 28 mm and 13 mm, respectively. FNA was read on-site as malignant, 21 (16%); benign, 100 (76.9%); suspicious, six (4%); atypical, 3 (2%); and inadequate sample, six (4%). Sixty-four LN were deferred for additional studies; 22 for immunocytochemical and 26 for Gimesa (GMS) stain and 21 for flow cytometry. Final FNA read was malignant in 28 (21%), benign in 103 (76%), suspicious in three (2%), and atypical in two (1%). Metastatic malignancies disclosed included Hodgkin's and Non-Hodgkin's lymphoma, melanoma, hepatoma, breast, lung, colon, renal, endometrial, Fallopian tube, and unknown carcinoma. The sensitivity, specificity, and accuracy of the final FNA read to predict malignancy were 100%. CONCLUSION EUS-guided FNA with additional ancillary studies is useful in disclosing metastatic ML from a variety of neoplasms. Due to its safety and accuracy profile, it should be considered the test of choice in evaluating abnormal ML in appropriately selected patients.

Abstract
We herein report a case of a gastric schwannoma with elevated preoperative serum carbohydrate antigen 19-9 (CA19-9) (155.2 U/ml, normal range 0-36.9 U/ml). A 59-year-old Japanese man was admitted to our hospital for treatment of a submucosal tumor of the stomach detected by barium meal, upper gastrointestinal endoscopy, and computed tomography. Endoscopic examination revealed a 3-cm diameter submucosal tumor in the antrum of the stomach, but biopsy of the lesion was unable to confirm the diagnosis. Positron emission tomography to evaluate the malignant potential showed a high uptake of (18)F-fluorodeoxyglucose in the tumor. Laparoscopy-assisted distal gastrectomy was therefore performed. The histopathological findings of the surgical specimen revealed a benign gastric schwannoma, positive for S-100 protein. The postoperative serum CA19-9 levels gradually decreased and normalized. To the best of our knowledge, this is the first report of a gastric schwannoma with elevated serum CA19-9.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) is widely used to investigate posterior mediastinal and upper abdominal lesions. Previously, we noticed that the aortoiliac bifurcation can be visualized by transduodenal EUS scanning, and the surrounding area might be a potential target for EUS-guided FNA. This study aimed to determine the feasibility of using EUS-guided FNA to study lesions near the aortoiliac bifurcation via the upper gastrointestinal approach. METHODS This study was a prospective pilot study of consecutive patients with a lesion of unknown origin near the aortoiliac bifurcation. RESULTS EUS-guided FNA was used in six patients. The aortoiliac bifurcation was visible from the inferior duodenal angle in all patients; however, the lesions could be visualized in only five patients (3 via the transduodenal approach, and 2 via the transgastric approach). In one patient with a lesion on the left side, the lesion could not be visualized by either the transgastric or transduodenal approach. In the other five patients, EUS-guided FNA was successful, and FNA specimens were adequate for histopathological assessment. The diagnoses were lymphoma (n = 3), plasmacytoma (n = 1), and neurinoma (n = 1). All lymphoma cases were subclassified as diffuse large B-cell lymphoma (n = 2) or grade 2 follicular lymphoma (n = 1). No complications were observed. CONCLUSIONS The aortoiliac bifurcation was visible in all patients by transduodenal EUS scanning. FNA of the legions near the aortoiliac bifurcation was possible in five of six patients by using either the transgastric or transduodenal approach.

Abstract
Aims. Our aim was to identify the factors that made the specimens inadequate and nondiagnostic in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy of suspected submucosal tumors (SMTs). Methods. From August 2001 to October 2009, 47 consecutive patients with subepithelial hypoechoic tumors originating in the fourth sonographic layer of the gastric wall suspected as GIST by standard EUS in Chiba University hospital underwent EUS-FNA for histologic diagnosis. We evaluated patient age, sex, location of lesion, size, pattern of growth in a stomach, and pattern of echography retrospectively. We defined a case of gaining no material or an insufficient material for immunohistological diagnosis as nondiagnostic. Results. The diagnostic yield of EUS-FNA for the diagnosis of gastric SMTs was 74.5%. Multivariate logistic regression analysis identified that age of under 60 years (compared with patients older than 60 years: odds ratio [OR] = 11.91, 95% confidence interval [CI] = 1.761-80.48) and location of SMT at lower third area (compared with upper or middle third area: OR = 10.62, 95% CI = 1.290-87.42) were the predictive factors for inadequate tissue yield in EUS-FNA. Conclusions. The factors associated with inadequate tissue yield in EUS-FNA were younger age and the location of lesion at lower third area in stomach.

Abstract
Primary tumors of the mediastinum and chest wall comprise a diverse group of conditions with a wide range of presentations. A thorough knowledge of thoracic anatomy is essential for appropriate diagnosis and treatment. Given their proximity to critical structures, treatment of these tumors is often challenging. Although surgery is the mainstay of therapy for most mediastinal and chest wall tumors, a multidisciplinary approach is valuable in many cases.

Gastrointest Endosc 2010; 71:913-9. [PMID: 20226456 DOI: 10.1016/j.gie.2009.11.044] [Citation(s) in RCA: 175] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2009] [Accepted: 11/13/2009] [Indexed: 02/07/2023]
Abstract
BACKGROUND Submucosal tumors (SMTs) comprise both benign and malignant lesions, and most of the gastric lesions tend to be malignant. The addition of EUS-guided FNA (EUS-FNA) has the potential to improve this distinction, but published series are limited. OBJECTIVE To evaluate the yield of EUS-FNA in gastric SMTs with referral to a criterion standard final diagnosis. DESIGN Retrospective study. SETTING Tertiary-care referral center. PATIENTS This study involved 141 consecutive patients with gastric SMTs, who underwent EUS-FNA from January 2000 to December 2008. Immunohistochemical staining with c-kit, CD34, actin, and S-100 antibodies was done if a spindle cell tumor was found. Based on FNA sample adequacy, and whether a specific diagnosis could be established, EUS-FNA results were categorized as diagnostic, suggestive, or nondiagnostic. The criterion standards for final diagnosis were the surgical histopathological results or the follow-up course for malignant, inoperable cases. INTERVENTION EUS-FNA. MAIN OUTCOME MEASUREMENTS Diagnostic yield of EUS-FNA and factors related to sampling adequacy for cytological and immunohistochemical evaluation. RESULTS A total of 141 patients (52% female, mean age 56.7 years) underwent EUS-FNA (range 1-5 passes). The overall results of EUS-FNA were diagnostic, suggestive, and nondiagnostic in 43.3%, 39%, and 17.7% of cases, respectively. Adequate specimens were obtained in 83% of cases, and 69 cases (48.9%) had a definitive final diagnosis. The most common gastric SMT was GI stromal tumor (59.5%). EUS-FNA results were 95.6% accurate (95% confidence interval [CI], 87.5%-99%) for the final diagnosis and 94.2% (95% CI, 85.6%-98.1%) accurate for differentiating potentially malignant lesions. A heterogeneous echo pattern was the only independent predictor for sampling adequacy (adjusted odds ratio 6.15; P = .002). There were no procedure-related complications. LIMITATIONS Possibility of selection bias. CONCLUSION EUS-FNA is an accurate method for diagnosis of gastric SMTs and for differentiating malignant lesions.

Abstract
Background Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mediastinal lymphadenopathy has been shown to be a valuable diagnostic tool in high-volume EUS centers (≥50 mediastinal EUS-FNA/endoscopist/year). Our goal was to assess the diagnostic accuracy of EUS-FNA and its impact on clinical management and costs in low-volume EUS centers (<50 mediastinal EUS-FNA/endoscopist/year). Methods Consecutive patients referred to two Dutch endoscopy centers in the period 2002–2008 for EUS-FNA of mediastinal lymphadenopathy were reviewed. The gold standard for a cytological diagnosis was histological confirmation or clinical follow-up of more than 6 months with repeat imaging. The impact of EUS-FNA on clinical management was subdivided into a positive impact by providing (1) adequate cytology that influenced the decision to perform surgery or (2) a diagnosis of a benign inflammatory disorder, and a negative impact which was subdivided into (1) false-negative or inconclusive cytology or (2) an adequate cytological diagnosis that did not influence patient management. Costs of an alternative diagnostic work-up without EUS-FNA, as established by an expert panel, were compared to costs of the actual work-up. Results In total, 213 patients (71% male, median age = 61 years, range = 23–88 years) underwent EUS-FNA. Sensitivity, specificity, and negative and positive predictive values were 89%, 100%, 80%, and 100%, respectively. EUS-FNA had a positive impact on clinical management in 84% of cases by either influencing the decision to perform surgery (49%) or excluding malignant lymphadenopathy (35%), and a negative impact in 7% of cases because of inadequate (3%) or false-negative (4%) cytology. In 9% of cases, EUS-FNA was performed without an established indication. Two nonfatal perforations occurred (0.9%). Total cost reduction was €100,593, with a mean cost reduction of €472 (SD = €607) per patient. Conclusions Mediastinal EUS-FNA can be performed in low-volume EUS centers without compromising diagnostic accuracy. Moreover, EUS-FNA plays an important role in the management of patients with mediastinal lymphadenopathy and reduces total diagnostic costs.

Abstract
OBJECTIVES Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has become widely accepted as an effective modality for obtaining tissue for primary diagnosis and staging. We have been using EUS-FNA since July 2001 and herein we summarize our experience over a 5-year period. METHODS A computer-based search for in-house EUS-FNA was performed in the pathology database from July 2001 to October 2006. To calculate the sensitivity, specificity and accuracy of EUS-FNA, the cytology diagnosis was compared with the surgical follow-up. RESULTS A total of 951 EUS-FNAs were performed during the study period and included 279 pancreatic solid lesions, 186 pancreatic cyst lesions, 249 lymph node aspirations, 111 gastrointestinal (GI) tract submucosal lesions, and 126 miscellaneous lesions. EUS-FNA had a very high sensitivity and accuracy for solid pancreatic lesions (94.7 and 97.7%, respectively), low sensitivity and accuracy but high specificity (47, 64.8 and 95%, respectively) for cystic lesions. Cyst fluid carcinoembryonic (CEA) levels were significantly higher in mucinous neoplasms than non-neoplastic cysts. EUS-FNA also had very high sensitivity and specificity for detecting metastatic carcinoma in lymph nodes (95 and 100%, respectively). GI submucosal spindle cell tumours were further classified with immunohistochemical stains performed either on a cell block or a core biopsy obtained via EUS guidance. CONCLUSIONS EUS-FNA has a very high sensitivity and accuracy for pancreatic solid lesions, but the sensitivity for cystic lesions is generally low. Cyst fluid chemical analysis for CEA is helpful, but the overlap between mucinous neoplasm and non-neoplastic cysts is significant. Recognizing GI contamination is important and immunohistochemical stains are useful for GI submucosal spindle cell lesions.

Abstract
Submucosal tumours (SMTs) are relatively common findings in patients undergoing endoscopy, especially in upper gastrointestinal (GI) tract. This term includes various non-neoplastic and neoplastic conditions. Endoscopic ultrasonography (EUS) is the best imaging procedure to characterise SMT and to determine the need for further explorations. In this review, the following issues will be addressed: the endosonographic features of SMT; the diagnostic accuracy of EUS; the ability of EUS to distinguish benign and malignant SMTs; the value of EUS-guided fine-needle aspiration (FNA); and the influence of EUS on clinical management.

Abstract
BACKGROUND EUS-guided FNA has been well documented to aid in the diagnosis of subepithelial lesions by providing cytologic material. Studies to date evaluating the sensitivity of EUS-FNA for the diagnosis of GI stromal cell tumors (GIST) have been small, and few have relied on surgical histologic diagnosis as the reference standard. OBJECTIVE Our purpose was to determine the diagnostic yield and sensitivity of EUS-FNA for the diagnosis of GIST and to identify EUS features of GIST that are predictive of the ability to obtain adequate tissue by EUS-FNA. DESIGN All patients with histologically confirmed, c-kit-positive GIST who underwent EUS-FNA from 1998 to 2006 were reviewed. EUS images were examined for mass size, shape, location, wall layer, heterogeneity, echogenicity, cystic spaces, lobulation, ulceration, and central umbilication. Needle gauge, number of needle passes, and presence of a cytologist during the EUS-FNA were recorded. RESULTS A total of 37 patients (29 with diagnostic FNA cytology; 8 with nondiagnostic cytology) met the inclusion criteria. The diagnostic yield and sensitivity of EUS-FNA cytology for the diagnosis of GIST was 78.4% (29/37). The sensitivity was 84.4% (27/32) for GISTs located in the stomach, but poor for lesions located in the duodenum because none of these tumors yielded diagnostic cytology (n = 3). An increase in size up to 10 cm, round/oval shape, and identification of the origin of GIST within a specific sonographic wall layer were statistically significant in their ability to predict adequate tissue yield. CONCLUSIONS The sensitivity of EUS-FNA cytology for the diagnosis of GIST is 78.4% and is influenced by size, location, shape, and layer of origin.

Abstract
Esophageal schwannoma is rare and it is difficult preoperatively to confirm a definitive diagnosis, even using current imaging techniques. We present a case of a benign esophageal schwannoma that was surgically excised and confirmed by immunohistochemical staining. Conventional radiological studies, including barium meal, computed tomography and endoscopic examination had shown a solid submucosal tumor of the upper thoracic esophagus but had been unable to confirm the diagnosis. Positron emission tomography was carried out to evaluate the malignant potential and showed a high uptake of 18F-fluorodeoxyglucose (FDG) into the tumor in both the early and delayed phase, suggesting that the tumor was a potentially malignant tumor such as a gastrointestinal stromal tumor. This is the first reported case of esophageal schwannoma that indicated a high FDG uptake. Although consensus has not been reached regarding the precise mechanism of FDG accumulation in schwannomas, we discuss our clinicopathological findings and review other studies of the subject.

Abstract
BACKGROUND Since its advent, endoscopic ultrasonography (EUS) has emerged as an invaluable tool in the diagnosis and management of gastrointestinal and adjacent cancers. Yet, it remains unclear how non-gastroenterologists who manage these malignancies use EUS in their practices. METHODS A link to a self-administered questionnaire, hosted on our university website, was emailed to 650 practicing medical, radiation, and surgical oncologists in the United States. RESULTS Data were analyzed from 100 responses. When available, the overall utilization of EUS for staging nonsmall cell lung cancer (NSCLC) was significantly low (19.0%), although available. When EUS was unavailable, majority of the patients with pancreatobiliary cancer (79%; P<0.01) were not referred for staging, unlike those with esophageal (57.9%) and rectal cancer (73.7%) were. EUS availability did not impact its use in staging gastric cancer. Majority of the respondents thought EUS made an impact in managing patients with rectal (89.5%), esophageal (84.5%), and pancreatobiliary cancers (58.5%) but not gastric (54.7%) or NSCLC (61.5%). In staging NSCLC, endoscopic ultrasound-guided fine-needle aspirate (35.7%) and mediastinoscopy (34.7%) were noted as the most accurate for tissue sampling of lymph nodes in levels 5, 7, and 8. EUS was deemed better than computerized tomography or magnetic resonance imaging by 42% in detecting small pancreatic tumors. Majority have not referred patients for EUS-guided celiac plexus neurolysis for palliation of pain in unresectable pancreatic cancer. CONCLUSIONS These data highlight the utilization of EUS that did not necessarily follow established guidelines. Further research is essential to evaluate obstacles to utilization of endoscopic ultrasound-guided fine-needle aspirate.

Abstract
Mucins are aberrantly expressed in various malignancies. We immunohistochemically tested mucins expression (MUC1, MUC2 and MUC5AC) in EUS-FNA samples from pancreatic occupying lesions for the diagnostic utility. The prevalence of MUC1, MUC2 and MUC5AC expression in pancreatic cancers were 77.5% (31/40), 10.0% (4/40) and 80.0% (32/40), respectively, and in the benign pancreatic diseases 25% (4/16), 31.3% (5/16) and 43.8% (7/16). MUC1 and MUC5AC significantly overexpressed in pancreatic cancer, and MUC1 negatively related with tumor differentiation degree (p < 0.05). The prevalence of MUC1, MUC2 and MUC5AC expression in pancreatic mucinous neoplasms were 66.7% (12/18), 38.9% (7/18) and 88.9% (16/18), respectively, and in the pancreatic non-mucinous neoplasms 60.5% (23/38), 5.3% (2/38) and 57.9% (22/38). MUC2 and MUC5AC significantly overexpressed in pancreatic mucinous neoplasms, especially MUC2 in benign mucinous neoplasms (p < 0.05). Compared with cytology alone, the combination test of MUC1+cytology, and MUC5AC+cytology could achieve higher sensitivity (85 vs. 65%, 100 vs. 65%) and accuracy (89.3% vs. 73.2%, 91.1% vs. 73.2%) for pancreatic cancer diagnosis; the combination test of MUC2 + cytology, and MUC5AC + cytology could achieve higher sensitivity (77.8% vs. 38.9%, 100% vs. 38.9%), and specificity (97.4% vs. 60.5%, 71.1% vs. 60.5%) accuracy (100% vs. 51.8%, 80.4% vs. 51.8%) for mucinous neoplasm diagnosis. The panel MUC1+/MUC2-/MUC5AC+/ was higher specific in pancreatic cancer diagnosis, as well as MUC1-/MUC2+/MUC5AC+/ in pancreatic mucinous neoplasms. Our observations suggest the mucins expression profile in EUS-FNA specimens has higher value for the diagnosis of pancreatic cancer and mucinous neoplasms.

Abstract
Endoscopic ultrasound-guided fine needle aspiration (EUS-guided FNA) is a highly sensitive and specific method for diagnosing pancreatic masses. Alternatively, EUS-guided needle core biopsies (NCB) have also been introduced. We sought to determine efficacies of pancreatic EUS-guided FNAs and NCBs. Records of consecutive EUS-guided FNAs received over a 24-mo-period were reviewed. Cases with concurrent NCBs were selected for the study. The diagnoses from the two modalities were compared and designated concordant (CC) or discordant (DC). Of 252 cases, 52 had concurrent NCBs. The final diagnoses included primary and secondary tumors. Of the 52 cases, 29/52 (55.8%) were CC and 23/52 (44.2%) were DC. The sensitivities for FNAs and NCBs were 95.0% and 67.6%, respectively. Both modalities were 100% specific. Direct comparison between EUS-guided FNAs and NCBs demonstrated that the former are more sensitive for diagnosing pancreatic neoplasms, both primaries and metastases. There was no correlation between CC/DC cases and type of neoplasm.

Abstract
AIM: To evaluate the role of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) in the preoperative diagnosis of gastrointestinal stromal tumor (GIST).
METHODS: From September 2002 to June 2006, Fifty-three consecutive EUS-FNAs of GI tract subepithelial hypoechoic tumors with continuity to proper muscle layer suspected as GIST by standard EUS were evaluated prospectively. The reference standards for the final diagnosis were surgery (n = 31), or clinical follow-up (n = 22). Additionally, immunophenotyping of specimens obtained by EUS-FNA and surgical resection specimens were compared.
RESULTS: In 2 cases puncture was not performed because of anatomical problems. The collection rate of adequate specimens from the GI tract subepithelial hypoechoic tumor with continuity to proper muscle layer was 82% (42/51). The diagnostic rate for the tumor less than 2 cm, 2 to 4 cm, and 4 cm or more were 71% (15/21), 86% (18/21), and 100% (9/9), respectively. In 29 surgically resected cases, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EUS-FNA using immunohistochemical analysis of GIST were 100% (24/24), 80% (4/5), 96% (24/25), 100% (4/4), and 97% (28/29), respectively. No major complications were encountered.
CONCLUSION: EUS-FNA with immunohistochemical analysis is a safe and accurate method in the prethera-peutic diagnosis of GIST. It should be taken into consideration in decision making, especially in early diagnosis following minimal invasive surgery for GIST.
