ABSTRACT
Objective:To analyze clinical characteristics of primary pancreatic lymphoma (PPL) patients.Methods:Clinical features of 22 patients diagnosed as PPL admitted to Peking Union Medical College Hospital from January 2002 to May 2023 were analyzed retrospectively.Results:The median age was 56.4±13.3 years. The median time from onset to diagnosis was 1.0 (1.0, 3.0) months. The main clinical manifestations were abdominal pain (15/22), weight loss (14/22) and jaundice (10/22). Elevated lactate dehydrogenase (LDH) was observed in 15/20 (75%) patients. Only 2 (2/9, 22.2%) patients had increased CA199 levels and 2 (2/9, 22.2%) patients had increased CEA levels. The maximum tumor diameter was 5.0 (3.8, 6.9) cm. Contrast-enhanced CT mostly showed low enhancement lesions. Major pancreatic duct dilatation were rare on CT scan (4/20). Fifteen patients were confirmed by pancreatic pathology, of which 8 were obtained by surgery, 4 were obtained by CT or ultrasound-guided percutaneous biopsy, and 3 were obtained by EUS-FNA. The main pathological type was diffuse large B-cell lymphoma (14/22). 19 patients received chemotherapy, and 6 patients died with a median follow-up of 5.0 (1.5, 35.5) months.Conclusions:PPL is rare and easy to be misdiagnosed. Elevated LDH levels, normal tumor markers, and non-dilatation of main pancreatic duct are important diagnostic clues. It is important to obtain pathology by EUS-FNA and other methods for definite diagnosis.
ABSTRACT
ObjectiveTo summarize the liver biopsy and clinical features of patients with liver injury of unknown origin, and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin. MethodsA retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital, Xiamen University, from January 2018 to February 2023. According to the proportion of the patients with different final diagnoses, the patients were divided into autoimmune liver disease (AILD) group, metabolic associated fatty liver disease (MAFLD) group, drug-induced liver injury (DILI) group, alcoholic liver disease (ALD) group, and unknown group. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Bonferroni analysis or the Dunnett’ T3 test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups; the Fisher’s exact test was used for comparison of categorical data between multiple groups. ResultsAll 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission, among whom 90 patients (95.7%) had a confirmed diagnosis based on liver biopsy and clinical features. There were 43 patients (45.7%) with AILD, 21 (22.3%) with MAFLD, 15 (16.0%) with DILI, 6 (6.4%) with ALD, 1 (1.1%) with AILD and MAFLD, 1 (1.1%) with hemochromatosis, 1 (1.1%) with Budd-Chiari syndrome, 1 (1.1%) with congenital hepatic fibrosis, and 1 (1.1%) with idiopathic portal hypertension, while 4 patients (4.3%) still had an unknown etiology after liver biopsy. There were significant differences between the patients with top five diagnoses in age (F=4.457, P<0.05) , body mass index (BMI) (F=3.245, P<0.05), aspartate aminotransferase (AST) (H=11.128, P<0.05), gamma-glutamyl transpeptidase (GGT) (H=24.789, P<0.05), alkaline phosphatase (ALP) (H=26.013, P<0.05), IgG (H=19.099, P<0.05), IgM (H=21.263, P<0.05), AMA-M2 positive rate (P<0.05), and ANA positive rate (P<0.05). Compared with the MAFLD group, the AILD group had significantly higher age, AST, GGT, and ALP and a significantly lower BMI; compared with the MAFLD group and the DILI group, the AILD group had significant increases in IgG and IgM; the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups. ConclusionAILD, MAFLD, and DILI are the most common causes in patients with liver injury of unknown origin. Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin, but it is still needed to make a comprehensive analysis based on clinical history, different types of liver injury, laboratory markers, and imaging data.

ABSTRACT
Objective:To explore the feasibility of smart phone real-time picture exchange-assisted telecytopathology for rapid on-site evaluation (tele-ROSE), and the role of tele-ROSE in improving the diagnostic efficiency of endoscopic physicians.Methods:Data of patients who underwent endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) from April 2020 to May 2021 in Qilu Hospital of Shandong University were retrospectively collected. Patients who didn't receive ROSE from April 2020 to October 2020 were enrolled in the non-ROSE group, and those who underwent ROSE from November 2020 to May 2021 were enrolled in the ROSE group, of which endosonographers used WeChat on the smartphone to send ROSE images to cytopathologists from November 2020 to March 2021 were the mobile phone group, and those whose ROSE results independently diagnosed by trained endosonographers from April 2021 to May 2021 were the self-ROSE group. Basic information, ROSE results, postoperative pathology and follow-up were compared, and the diagnostic effectiveness of tele-ROSE was analyzed.Results:A total of 188 cases were included, of which 179 cases (95.2%) were solid pancreatic lesions and 9 (4.8%) were enterocoelia lesions. There was no significant difference in the puncture time among the non-ROSE, mobile phone and self-ROSE groups [3 (3, 4) VS 3 (3, 4) VS 3 (2, 4), H=1.320, P=0.517]. With the final diagnosis as the golden standard, the sensitivity, the specificity, the accuracy, the positive predictive value, the negative predictive value and Kappa value of the non-ROSE group were 80.6% (58/72), 89.5% (17/19), 82.4% (75/91), 96.7% (58/60), 54.8% (17/31), and 0.6 respectively. The corresponding indices in the ROSE group were 97.4% (74/76), 100.0% (21/21), 97.9% (95/97), 100.0% (74/74), 91.3% (21/23), and 0.9 respectively, those of the mobile phone group were 95.2% (40/42), 100.0% (10/10), 96.2% (50/52), 100.0% (40/40), 83.3% (10/12), and 0.9 respcetively, and those of the self-ROSE group were 100.0% (34/34), 100.0% (11/11), 100.0% (45/45), 100.0% (34/34), 100.0% (11/11), and 1.0 respectively. The sensitivity ( P=0.002), the accuracy ( P=0.001) and the negative predictive value ( P=0.009) of the ROSE group were significantly higher than those of the non-ROSE group, and there was no significant difference in other diagnostic efficacy indices ( P>0.05). There was no significant difference between the mobile phone group and the self-ROSE group in diagnostic efficacy ( P>0.05). Conclusion:Instant smartphone-assisted tele-ROSE through WeChat can well meet the needs of pathologists and endoscopic physicians. After the application of tele-ROSE training, the diagnostic accuracy of endoscopic physicians is equivalent to that of cytopathologist, which helps to obtain more sufficient specimens under endoscopy and improve the diagnostic accuracy of EUS-FNA.
ABSTRACT
Objective@#To determine the risk of malignancy of Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) indeterminate Thyroid Nodules (Bethesda III, IV and V) by combining cytologic (TSBRTC) and Thyroid Imaging Reporting and Data Systems (TI-RADS) ultrasonographic features based on final histopathology.@*Methods@#Design: Retrospective review of records. Setting: Tertiary Private Training Hospital. Participants: 551 records. @*Results@#Among 81 eligible participants, 59 out of 84 nodules (70.24%) wer malignant on histopathology. The malignancy risk of Bethesda classification was 60.87% (28 out of 46) for Bethesda III, 57.14% (8 out of 14) for Bethesda IV and 95.83% for Bethesda V. The malignancy risk for TI-RADS categories was 0 % (0/1) for TI-RADS 2, 50% (10 out of 20) for TI-RADS 3, 71.05 % for TI-RADS 4 and 91.67 % for TI-RADS 5. The highest risk of malignancy (100%) was associated with [Bethesda IV/TI-RADS 1, 2, and 3], [Bethesda V/TI-RADS 1, 2 and 3 [Bethesda IV and V/TI-RADS 1, 2 and 3] and [Bethesda IV/TI-RADS 5]. The lowest risk of malignancy (33.33%) was associated with [Bethesda III/TI-RADS1, 2 and 3]. A high Bethesda classification (Bethesda V) was almost 5x more likely to have a malignant anatomorphology compared with Bethesda III (p = .05) while a TI-RADS 4 or 5 category was almost 5x more likely to have a malignant anatomorphology compared to TI-RADS 1, 2 or 3 (p = .026).@*Conclusion@#This study showed that TI-RADS scoring is a sensitive diagnostic classification in recognizing patients with thyroid cancer and combining Bethesda classification and TI-RADS scoring increases the sensitivity in the diagnosis of malignant thyroid nodules. A higher likelihood of malignancy is associated with higher Bethesda classification and TI-RADS scoring.

Objective To investigate the influencing factors and establish a model predicting the performance of needle visualization in fine-needle aspiration (FNA) of thyroid nodules. Methods This study prospectively included 175 patients who underwent FNA of thyroid nodules in the Department of Ultrasound in China-Japan Friendship Hospital and compared the display of the needle tips in the examination of 199 thyroid nodules before and after the application of needle visualization.We recorded the location,the positional relationship with thyroid capsule,ultrasonic characteristics,and the distribution of the soft tissue strip structure at the puncture site of the nodules with unclear needle tips display before using needle visualization.Furthermore,according to the thyroid imaging reporting and data system proposed by the American College of Radiology,we graded the risk of the nodules.Lasso-Logistic regression was employed to screen out the factors influencing the performance of needle visualization and establish a nomogram for prediction. Results The needle tips were not clearly displayed in the examination of 135 (67.8%) and 53 (26.6%) nodules before and after the application of needle visualization,respectively,which showed a significant difference (P<0.001).Based on the positional relationship between the nodule and capsule,anteroposterior/transverse diameter (A/T) ratio,blood supply,and the distribution of subcutaneous strip structure at the puncture site,a nomogram was established to predict the probability of unclear display of the needle tips after application of needle visualization.The C-index of the prediction model was 0.75 (95%CI=0.67-0.84) and the area under the receiver operating characteristic curve was 0.72.The calibration curve confirmed the appreciable reliability of the prediction model,with the C-index of 0.70 in internal validation. Conclusions Needle visualization can improve the display of the needle tip in ultrasound-guided FNA of thyroid nodules.The nomogram established based on ultrasound features such as the positional relationship between the nodule and capsule,A/T ratio,blood supply,and the distribution of subcutaneous strip structure at the puncture site can predict whether needle visualization is suitable for the examination of nodules.

ABSTRACT
Objective:To investigate the diagnostic value of endoscopic ultrasound elastography (EUS-E) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for malignant occupying lesions in gastrointestinal adjacent tissue.Methods:Clinical data of 54 patients (57 lesions) undergoing EUS-FNA from January 2020 to April 2021 in the General Hospital of Ningxia Medical University were collected. Thirty patients (31 lesions) who received FNA assisted by EUS-E from May 2020 to February 2021 were enrolled in the EUS-E group, and 24 patients (26 lesions) who underwent routine EUS-FNA without EUS-E in the non-EUS-E group. The diagnostic efficacy of EUS-FNA was evaluated.The diagnostic efficacy of EUS-E group and non EUS-E group was compared. EUS-E score of EUS-E group was analyzed.Results:The overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA in the diagnosis of malignant occupying lesions in gastrointestinal adjacent tissue were 80.5% (33/41), 100.0% (16/16), 100.0% (33/33), 66.7% (16/24) and 86.0% (49/57), respectively. There were no significant differences in sensitivity [78.6% (22/28) VS 84.6% (11/13), P=0.232] or accuracy [83.8% (31/37) VS 90.0% (18/20), P=0.156] of EUS-FNA for pancreatic lesions and other lesions (mediastinal and celiac lesions). Postoperative complications occurred in 1 patient (1.85%, 1/54). Also there were no significant differences in sensitivity [84.0% (21/25) VS 81.3% (13/16), P=0.186] or accuracy [87.1% (27/31) VS 88.5% (23/260, P=0.186] of diagnosis of malignant occupying lesions between EUS-E group and non-EUS-E group. In the EUS-E group, EUS-E score≥3 was highly consistent with the definite diagnosis ( Kappa=0.63). Conclusion:EUS-FNA is a safe and effective cytological and pathological method for diagnosis in gastrointestinal adjacent tissue. EUS-E score can well predict benign and malignant lesions, but EUS-FNA assisted by EUS-E does not show superiority in diagnostic sensitivity or accuracy.
ABSTRACT
To evaluate the diagnostic value of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for portal vein tumor thrombus, data of patients with digestive system malignant tumors combined with portal vein tumor thrombus diagnosed by CT or magnetic resonance imaging who underwent EUS-FNA from April 2015 to July 2020 in the Second Affiliated Hospital of Soochow University were collected. A total of 7 patients were included, with 2 cases of primary hepatocellular carcinoma, 3 cases of primary pancreatic carcinoma and 2 cases of primary gastric cancer. EUS-FNA was successfully performed in 7 patients with portal vein embolus. Pathological examination of portal vein embolus showed 5 cases of malignant tumor. No tumor cell was found in 2 cases. There were no complications such as local hematoma, abdominal hemorrhage or infection in all patients. EUS-FNA is safe and effective for patients diagnosed as having malignant tumors with portal vein embolus.
ABSTRACT
Objective:To explore the diagnostic value of endoscopic ultrasonography (EUS) for pancreatic cystic lesions (PCLs).Methods:Clinical data of 211 patients with PCLs, who underwent EUS at least once and were pathologically confirmed in First Affiliated of Naval Medical University from January 2011 to December 2021 was retrospectively analyzed. EUS imaging characteristics, biochemical analysis of cystic fluid and pathological data were recorded. The pathological diagnosis results of intraductal papillary mucinous neoplasms and mucinous cystic neoplasms were included in the mucinous lesion group, while pancreatic pseudocyst, serous cystic neoplasms, solid pseudopapillary neoplasms and pancreatic neuroendocrine tumors were included as non-mucinous lesions group; those with pancreatic ductal adenocarcinoma, adenocarcinoma or with atypical or cancer cells were included as malignant lesion group, and the else were included as benign lesions group. The level of CEA in cyst fluid between mucinous and non-mucinous lesions and the level of amylase in cyst fluid between benign and malignant lesion groups were compared, and the area under the curve (AUC) was calculated by drawing receiver operating characteristic curve (ROC), which was used to analyze the differential diagnosis efficiency of cyst fluid CEA and amylase test indexes. The basic characteristics and EUS imaging characteristics, and the diagnostic efficiency of EUS and liquid-based cytology and histopathology between benign and malignant lesions were studied and analyzed.Results:Among the 211 PCL patients, cyst fluid was obtained in 201 patients, of which 188 patients (93.5%) underwent cytological examination, and 33 patients were diagnosed with an accuracy rate of 17.6%; 41 cases were obtained for histological examination, and 23 cases were confirmed, with an accuracy rate of 56.1%. Among all confirmed cases, 45 cases had benign lesions, including 22 cases of mucinous lesions and 23 cases of non-mucinous lesions, with the cyst fluid CEA of 1458.16(19.80, 1500.00), 4.4(0.50, 341.14)ng/ml respectively, and the difference of cyst fluid CEA level between mucinous and non-mucinous lesions was statistically significant( P<0.05). The cyst fluid CEA<10.15 ng/ml could be used to diagnose non-mucinous PCLs with the sensitivity of 89.5%(95% CI0.686-0.981), and the specificity of 66.7%(95% CI0.438-0.837). The cyst fluid amylase levels in benign and malignant lesions were 379.00(50.00, 18405.50), 42.00(13.50, 340.00)U/L, and the difference was statistically significant ( P<0.05). The cyst fluid amylase>747.50 U/L might help to identify benign PCLs with the sensitivity of 91.7%(95% CI0.646-0.996), and the specificity of 48.0%(95% CI0.300-0.665). EUS showed that the proportion of cyst wall thickening, main duct dilatation and cystic solid components in patients with malignant lesions was significantly higher than that in patients with benign lesions, and the differences were statistically significant ( P<0.05), while there was no significant difference in the proportion of cyst wall nodules and cystic septum between the two groups. The accuracy of EUS combined with liquid-based cytology or histopathology in malignant lesions was over 80%. Conclusions:The cyst fluid CEA level can help to differentiate non-mucinous PCLs from mucinous PCLs, and the cystic amylase level could be useful to identify the benign and malignant PCLs. EUS combined with cytology or histology had high diagnostic value for malignant or potentially malignant PCLs, and EUS-FNA examination can be recommended as soon as possible for those with high-risk factors.
ABSTRACT
Objective:To investigate the clinical efficacy of ultrasound-guided percutaneous sclerotherapies for a simple renal cyst.Methods:A total of 120 patients with a simple renal cyst who received treatment in the Department of Urology, Changxing People's Hospital from January 2017 to January 2020 were included in this study. All patients underwent ultrasound-guided percutaneous sclerotherapies followed by medical absolute ethanol perfusion (retention treatment group, n = 40), medical absolute ethanol flushing (flushing replacement group, n = 40), and polidocanol perfusion (polidocanol treatment, n = 40). General data, operation, the incidence of complications, and surgical efficacy were compared between the three groups. Results:There were no significant differences in sex, age, course of the disease, cyst size, and cyst distribution among the three groups (all P > 0.05). The Visual Analog Scale score, length of hospital stay, and medical cost in the polidocanol treatment group were (1.98 ± 0.63) points, (3.54 ± 1.25) days, and (6271.34 ± 831.20) yuan respectively, which were significantly lower than those in the retention treatment group [(3.98 ± 1.26) points, (5.87 ± 1.76) days, (8798.45 ± 981.76) yuan and flushing replacement group [(3.05 ± 1.02) points, (4.35 ± 1.42) days, (7 128.19 ± 921.70) yuan]. There were significant differences in The Visual Analog Scale score, length of hospital stay, and medical cost between groups ( t = 8.97, 6.82, 12.42, all P < 0.001). The incidence of complications in the retention treatment, flushing replacement, and polidocanol treatment groups was 25.00% (10/40), 12.50% (5/40), 5.00% (2/40), respectively ( χ2 = 6.71, P = 0.035). The total response rate in the retention treatment, flushing replacement, and polidocanol treatment groups was 75.00% (30/40), 82.50% (33/40) and 97.50% (39/40), respectively ( χ2 = 8.23, P = 0.016). Conclusion:Ultrasound-guided percutaneous sclerotherapy with polidocanol is effective on a simple renal cyst. The sclerotherapy with polidocanol has a low incidence of complications, shortens the postoperative rehabilitation process, and has a good prognosis.
ABSTRACT
To evaluate the diagnostic value and safety of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with biopsy-negative malignant gastrointestinal stricture, a retrospective analysis was performed on data of patients whose computed tomography scan showed gastrointestinal malignant tumor with complete lumen stricture and endoscopic biopsy results showed negative, who underwent EUS-FNA in the Second Affiliated Hospital of Soochow University from July 2016 to January 2020. Perioperative complications, technical success rate and accuracy of EUS-FNA were analyzed. Eleven cases included in the study, including 7 males and 4 females, with mean age of 60.3 years. There were 8 esophageal strictures and 3 rectal strictures. All patients successfully underwent EUS-FNA, and malignant tumor was found in 10 cases and no tumor cell was found in 1 case. No complications were reported. EUS-FNA is a safe and valuable approach to diagnosing biopsy-negative malignant gastrointestinal strictures.
ABSTRACT
ObjectiveTo investigate the effect of different cytopathological grading standards on the efficiency of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of pancreatic cancer. MethodsRelated clinical data and pancreatic cytopathological results were collected from 256 patients with pancreatic space-occupying lesions who underwent EUS-FNA in The First Affiliated Hospital of Anhui Medical University from May 2011 to March 2019, and the influencing factors for the diagnostic efficiency of EUS-FNA were analyzed based on surgical pathology and follow-up results. The independent samples t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of different cytopathological grading standards in the diagnosis of pancreatic cancer. ResultsA total of 67 patients who were lost to follow-up were excluded, and a total of 189 patients were included in the study. According to the Papanicolaou cytopathological standard, there were 47 cases of heterotypic cells, 25 cases of suspected cancer cells, 20 cases of cancer cells, and 97 cases without tumor cells based on EUS-FNA. A total of 133 patients were confirmed to have pancreatic cancer by postoperative pathology and follow-up results, among whom 52 had no tumor cells, 36 had heterotypic cells, 25 had suspected cancer cells, and 20 had cancer cells based on cytopathological results. EUS-FNA had a true positive rate of 6090% (81 patients) and a false negative rate of 39.10% (52 patients) in the diagnosis of pancreatic cancer; for the 56 patients without pancreatic cancer, EUS-FNA had a false positive rate of 19.64% (11 patients) and a true negative rate of 80.36% (45 patients). EUS-FNA had an area under the ROC curve of 0.643 (95% confidence interval: 0.561-0.724) in the diagnosis of pancreatic cancer. In combination with different cytopathological grading standards and with the diagnostic criteria of “the identification of heterotypic cells or suspected cancer cells or cancer cells was considered positive”, “the identification of suspected cancer cells or cancer cells was considered positive”, and “the identification of cancer cells was considered positive”, the results showed that the diagnostic criteria of “the identification of heterotypic cells or suspected cancer cells or cancer cells was considered positive” improved the efficiency of EUS-FNA in the diagnosis of pancreatic cancer, with a sensitivity of 50.38% and a specificity of 75.00%. Among the 189 patients, 13 (6.88%) experienced complications after EUS-FNA, which included hyperamylasemia and abdominal pain. ConclusionThe combination of different cytopathological grading standards can help improve the efficiency of EUS-FNA in the diagnosis of pancreatic cancer.
ABSTRACT
Follicular thyroid carcinoma(FTC) is a differentiated thyroid carcinoma originated from thyroid follicular cells. The sensitivity and specificity of ultrasound classification and scoring systems in diagnosis of follicular carcinoma are insufficient. Ultrasound guided fine needle aspiration(US-FNA) can screen but cannot diagnose FTC. Core needle biology(CNB) can reduce repeated FNA and unnecessary operations, and improve the diagnostic accuracy of FN patients, but CNB still has many controversies. Ultrasound guided FNA combined with gene detection (such as RAS) can significantly improve the diagnostic accuracy of follicular neoplasm. In recent years, artificial intelligence assisted diagnosis has shown high specificity in distinguishing FTC from follicular thyroid adenoma (FTA), which is conducive to the standardized treatment of thyroid follicular neoplasm. In this paper, the research progress of ultrasound based in diagnosis of FTC was reviewed.
ABSTRACT
Objective:To assess rapid on-line evaluation (ROLE) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic masses.Methods:Data of patients with solid pancreatic masses who underwent EUS-FNA in Peking University First Hospital from October 2017 to October 2019 were retrospectively analyzed. Patients were divided into the ROLE group and the control group. The number of FNA passes in ROLE group was decided by the cytopathologist based on the number of pancreatic tissue cells or heteromorphic cells obtained, while that in the control group was decided by the endoscopy physician according to the visual observation of tissue strips. The cytological and histological diagnosis of EUS-FNA specimen were made by another cytopathologist. The gold standard for final diagnosis was based on the histological diagnosis of surgically resected specimens. For patients who did not undergo surgical treatment, the final diagnosis was made based on the clinical course, imaging, tumor markers and feedback on treatment. The diagnostic yield, the accuracy, the sensitivity, the specificity, FNA passes, puncture time and adverse events were compared between the two groups.Results:A total of 87 patients were enrolled, 51 in the ROLE group and 36 in the control group. The diagnostic yield of the ROLE group was higher than that of the control group without significant difference [98.0% (50/51) VS 86.1%(31/36), P=0.078]. The number of FNA passes in the ROLE group was significantly less than that in the control group (median 2 VS 3, P<0.001). No significant difference in mean FNA puncture time was found between the ROLE group and the control group (19.4 min VS 18.5 min, P=0.089). There were no significant differences between the two groups with regard to the diagnostic yield, the sensitivity, the specificity, the positive predictive value, the negative predictive value or the incidence of adverse events. Conclusion:ROLE of EUS-FNA for pancreatic solid tumor may improve tissue acquisition for puncture, reduce the number of FNA passes, and may not significantly increase the procedure time and risk of puncture.
ABSTRACT
SUMMARY OBJECTIVE: To evaluate the value of EBUS-TBNA in the diagnosis of lung and mediastinal lesions. METHODS: Prospective cohort study that included 52 patients during a 2-year period (2016 to 2018) who underwent EBUS-TBNA. RESULTS: Among the 52 individuals submitted to the procedure, 22 (42.31%) patients were diagnosed with locally advanced lung cancer (N2 or N3 lymph node involvement). EBUS-TBNA confirmed the diagnosis of metastases from other extrathoracic tumors in the mediastinum or lung in 5 patients (9.61%), confirmed small cell lung cancer in 3 patients (5.76%), mediastinal sarcoidosis in 1 patient (1.92%), and reactive mediastinal lymph node in 8 patients (15.38%); insufficient results were found for 3 patients (5.76%). Based on these results, EBUS-TBNA avoided further subsequent surgical procedures in 39 of 52 patients (75%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 86%, 100%, 100%, 77%, and 90%, respectively. No major complications were observed. CONCLUSIONS: EBUS-TBNA is a safe, effective, and valuable method. This technique can significantly reduce the rate of subsequent surgical procedures required for the diagnosis of lung and mediastinal lesions.
RESUMO OBJETIVO: Avaliar a importância da ecoendoscopia endobrônquica com punção por agulha fina (Ebus-TBNA) no diagnóstico das lesões pulmonares e mediastinais. MÉTODOS: Estudo prospectivo e do tipo coorte, no qual foram incluídos 52 pacientes, durante o período de dois anos (2016 a 2018), submetidos ao procedimento de Ebus-TBNA. RESULTADOS: Do total de 52 indivíduos submetidos ao procedimento, 22 (42,31%) pacientes foram diagnosticados com neoplasia pulmonar localmente avançada (N2 ou N3). O método confirmou o diagnóstico de metástases de outros tumores extratorácicos no mediastino ou pulmão em cinco pacientes (9,61%), três pacientes (5,76%) com carcinoma de pequenas células, um paciente (1,92%) com sarcoidose, oito pacientes (15,38%) com linfonodomegalias reacionais/inflamatórias e resultado insuficiente em três pacientes (5,76%). O Ebus-TBNA evitou a realização de outros procedimentos cirúrgicos subsequentes em 39 de 52 (75%) pacientes. Foram calculados os valores de sensibilidade de 86%, especificidade de 100%, valor preditivo positivo de 100%, valor preditivo negativo de 77% e acurácia de 90%. Não foram observadas complicações maiores pelo método neste estudo. CONCLUSÃO: O Ebus-TBNA é um método seguro, eficaz e de relevante importância. Este exame pode reduzir significativamente o número de procedimentos invasivos subsequentes necessários para o diagnóstico das lesões pulmonares e mediastinais.

Pancreatic metastases of papillary thyroid carcinoma (PTC) are exceptional. We report a 80-year-old man consulting for obstructive jaundice and dysphonia. Abdominal ultrasonography showed biliary dilation and abdominal magnetic resonance imaging (MRI) showed a pancreatic head mass of 36 mm. A left vocal cord paralysis was confirmed and cervical computed tomography (CT) showed multiple thyroid nodules of up to 35 mm associated with bilateral cervical lymph nodes (LN). Positron emission tomography ( 18 F-FDG PET/CT) evidenced hyper-metabolic activity in bilateral cervical LN, lungs, pancreas and left intercostal soft tissue, as well as left gluteus. Thyroid biopsy reported a tall-cell variant of PTC, and endoscopic ultrasound guided fine needle aspiration (EUS-FNA) of pancreatic mass confirmed PTC metastasis. The molecular study was positive for BRAFV600E. Pancreatic metastasis from PTC can be accurately diagnosed with 18 F-FDG PET/CT and EUS-FNA, which is consistent with a predominant expression of BRAFV600E mutation and, thus, an aggressive presentation with poor short-term survival.

ABSTRACT Objective: To determine the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in non-neoplastic patients with isolated intrathoracic lymphadenopathy (IL). Methods: This was a retrospective study of patients with isolated IL referred for EBUS-TBNA. We calculated the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of EBUS-TBNA in the diagnosis of granulomatous, reactive, and neoplastic lymphadenopathy. In cases of nonspecific granulomas, reactive lymphadenopathy, or inconclusive results, a definitive diagnosis was established by other diagnostic procedures or during a follow-up period of at least 18 months. Results: Among the 58 patients included in the study, EBUS-TBNA established a diagnosis of granulomatous disease in 22 (38%), reactive lymphadenopathy in 15 (26%), cancer in 8 (14%), and other diseases in 3 (5%). Results were inconclusive in 10 (17%), the diagnosis being established by other bronchoscopic procedures in 2 (20%) and by surgical procedures in 8 (80%). A final diagnosis of reactive lymphadenopathy was established in 12. Of those, 11 (92%) had their diagnosis confirmed during follow-up and 1 (8%) had their diagnosis confirmed by mediastinoscopy. In another 3, a final diagnosis of sarcoidosis or neoplasm was established. For the diagnosis of granulomatous disease, neoplasms, and reactive lymphadenopathy, EBUS-TBNA was found to have a sensitivity of 73%, 68%, and 92%, respectively; a specificity of 100%, 100%, and 93%, respectively; an accuracy of 86%, 93%, and 93%, respectively; a PPV of 100%, 100%, and 80%, respectively; and an NPV of 78%, 92%, and 98%, respectively. Conclusions: In non-neoplastic patients, granulomatous disease and reactive lymphadenopathy appear to be common causes of isolated IL. EBUS-TBNA shows promising results as a first-line minimally invasive diagnostic procedure. The results obtained by EBUS-TBNA can be optimized by examining clinical and radiological findings during follow-up or by comparison with the results obtained with other bronchoscopic methods.
RESUMO Objetivo: Determinar o rendimento diagnóstico da endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA, aspiração transbrônquica com agulha guiada por ultrassonografia endobrônquica) em pacientes não neoplásicos com linfonodomegalia intratorácica (LI) isolada. Métodos: Estudo retrospectivo com pacientes com LI isolada encaminhados para EBUS-TBNA. Foram calculados a sensibilidade, especificidade, precisão, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) da EBUS-TBNA no diagnóstico de linfadenopatia granulomatosa, reacional e neoplásica. Em casos de granulomas inespecíficos, linfadenopatia reacional ou resultados inconclusivos, o diagnóstico definitivo foi estabelecido por meio de outros procedimentos diagnósticos ou ao longo de pelo menos 18 meses de acompanhamento. Resultados: Nos 58 pacientes incluídos, a EBUS-TBNA permitiu que se estabelecesse o diagnóstico de doença granulomatosa em 22 (38%), linfadenopatia reacional em 15 (26%), câncer em 8 (14%) e outras doenças em 3 (5%). Os resultados foram inconclusivos em 10 (17%), nos quais o diagnóstico foi feito por meio de outros procedimentos broncoscópicos, em 2 (20%), ou de procedimentos cirúrgicos, em 8 (80%). O diagnóstico final de linfadenopatia reacional foi feito em 12. Destes, 11 (92%) receberam confirmação diagnóstica durante o acompanhamento e 1 (8%), por meio de mediastinoscopia. Em outros 3, o diagnóstico final foi sarcoidose ou neoplasia. Para o diagnóstico de doença granulomatosa, câncer e linfadenopatia reacional, a EBUS-TBNA apresentou sensibilidade de 73%, 68% e 92%, respectivamente; especificidade de 100%, 100% e 93%, respectivamente; precisão de 86%, 93% e 93%, respectivamente; VPP de 100%, 100% e 80%, respectivamente; VPN de 78%, 92% e 98%, respectivamente. Conclusões: Em pacientes não neoplásicos, doenças granulomatosas e linfadenopatia reacional parecem ser causas comuns de LI isolada. A EBUS-TBNA apresenta resultados promissores como procedimento diagnóstico minimamente invasivo de primeira linha. Os resultados obtidos pela EBUS-TBNA podem ser otimizados pelos achados clínicos e radiológicos durante o acompanhamento ou pela comparação com os resultados de outros métodos broncoscópicos.

ABSTRACT Objective: Lung cancer (LC) is one of the leading causes of death worldwide. Accurate mediastinal staging is mandatory in order to assess prognosis and to select patients for surgical treatment. EBUS-TBNA is a minimally invasive procedure that allows sampling of mediastinal lymph nodes (LNs). Some studies have suggested that EBUS-TBNA is preferable to surgical mediastinoscopy for mediastinal staging of LC. The objective of this systematic review and meta-analysis was to compare EBUS-TBNA and mediastinoscopy in terms of their effectiveness for mediastinal LN staging in potentially operable non-small cell lung cancer (NSCLC). Methods: This was a systematic review and meta-analysis, in which we searched various databases. We included studies comparing the accuracy of EBUS-TBNA with that of mediastinoscopy for mediastinal LN staging in patients with NSCLC. In the meta-analysis, we calculated sensitivity, specificity, positive likelihood ratios, and negative likelihood ratios. We also analyzed the risk difference for the reported complications associated with each procedure. Results: The search identified 4,201 articles, 5 of which (with a combined total of 532 patients) were selected for inclusion in the meta-analysis. There were no statistically significant differences between EBUS-TBNA and mediastinoscopy in terms of the sensitivity (81% vs. 75%), specificity (100% for both), positive likelihood ratio (101.03 vs. 95.70), or negative likelihood ratio (0.21 vs. 0.23). The area under the summary ROC curve was 0.9881 and 0.9895 for EBUS-TBNA and mediastinoscopy, respectively. Although the number of complications was higher for mediastinoscopy, the difference was not significant (risk difference: −0.03; 95% CI: −0.07 to 0.01; I2 = 76%). Conclusions: EBUS-TBNA and mediastinoscopy produced similar results for mediastinal staging of NSCLC. EBUS-TBNA can be the procedure of first choice for LN staging in patients with NSCLC.
RESUMO Objetivo: O câncer de pulmão (CP) é uma das principais causas de morte no mundo. Um estadiamento mediastinal preciso é obrigatório para avaliação do prognóstico e seleção de pacientes para tratamento cirúrgico. EBUS-TBNA é um procedimento minimamente invasivo que permite a amostragem de linfonodos mediastinais. Alguns estudos sugerem que a EBUS-TBNA é preferível que a mediastinoscopia cirúrgica no estadiamento mediastinal do CP. O objetivo desta revisão sistemática e meta-análise foi comparar a eficácia da EBUS-TBNA e da mediastinoscopia no estadiamento linfonodal mediastinal do câncer de pulmão de células não pequenas (CPCNP) potencialmente operável. Métodos: Foram pesquisados diversos bancos de dados. Estudos comparando a precisão da EBUS-TBNA e da mediastinoscopia no estadiamento linfonodal mediastinal em pacientes com CPCNP foram incluídos. Na meta-análise, foram calculadas sensibilidade e especificidade, bem como razões de verossimilhança positiva e negativa. A diferença de risco de complicações relatadas para cada procedimento também foi analisada. Resultados: A pesquisa identificou 4.201 artigos, dos quais 5 foram selecionados para a meta-análise (total combinado de 532 pacientes). Não houve diferenças estatisticamente significativas entre EBUS-TBNA e mediastinoscopia: sensibilidade (81% vs. 75%), especificidade (100% para ambas), razão de verossimilhança positiva (101,03 vs. 95,70) e razão de verossimilhança negativa (0,21 vs. 0,23). A área sob a curva summary ROC para EBUS-TBNA e para mediastinoscopia foi de 0,9881 e 0,9895, respectivamente. Embora o número de complicações tenha sido maior para mediastinoscopia, não foi encontrada diferença significativa (diferença de risco: −0,03; IC95%: −0,07 to 0,01; I2 = 76%). Conclusões: EBUS-TBNA e mediastinoscopia apresentaram resultados semelhantes no estadiamento mediastinal do CPCNP. EBUS-TBNA pode ser o procedimento de primeira escolha no estadiamento linfonodal em pacientes com CPCNP.

RESUMEN La biopsia aspirativa con aguja fina guiada por tomografía ha ocupado el estándar mundial como punto de partida más exacto ante la conducta y el pronóstico de lesiones sugestivas de cáncer de pulmón. Se realizó un estudio epidemiológico de intervención, analítico, prospectivo, cuasi-experimental, en una cohorte de 78 pacientes con lesiones sugestivas de cáncer de pulmón con el objetivo de evaluar la utilidad de la BAAF guiada por Tomografía Axial Computarizada en el diagnóstico histológico de lesiones sugestivas de cáncer de pulmón en el Provincial Clínico Quirúrgico Docente "Celia Sánchez Manduley" de Manzanillo. Se incluyeron 9 casos mayores de 80 años, el 40% de los pacientes estuvieron en edades entre 50 y 64 años, con una media de 63,3. El lóbulo superior derecho presentó el 89% de las lesiones. La distancia media entre la piel y el centro del tumor fue de 4,3 cm. La mayor positividad se obtuvo en el lóbulo superior derecho con un 82,5%. El diagnóstico histológico evidenció la presencia de procesos benignos en el 20,7% de los casos. El adenocarcinoma ocupó el 51,3% seguido del carcinoma de células no pequeñas (21,8%). El riesgo relativo de resultar no útil para diagnóstico fue más alto en lesiones pequeñas (4,3). Se presentó neumotórax como complicación en dos pacientes. La biopsia aspirativa con aguja fina guiada por tomografía en lesiones pulmonares es un procedimiento seguro, con baja de tasa de complicaciones, permitió definir con seguridad las características histológicas de las lesiones pulmonares en la mayor parte de las localizaciones pulmonares.
ABSTRACT CT-guided fine needle aspiration biopsy has become the world standard as the most accurate starting point for the behavior and prognosis of lesions suggestive of lung cancer. An epidemiological, prospective, quasi-experimental, epidemiological intervention study was conducted in a cohort of 78 patients with lesions suggestive of lung cancer with the aim of evaluating the usefulness of BAAF guided by Computerized Axial Tomography in the histological diagnosis of lesions, suggestive of lung cancer in the Provincial Clinical Surgical Teaching "Celia Sánchez Manduley" of Manzanillo. We included 9 cases older than 80 years, 40% of the patients were between 50 and 64 years old, with a mean of 63.3. The right upper lobe presented 89% of the lesions. The average distance between the skin and the center of the tumor was 4.3 cm. The highest positivity was obtained in the right upper lobe with 82.5%. The histological diagnosis evidenced the presence of benign processes in 20.7% of the cases. Adenocarcinoma accounted for 51.3% followed by non-small cell carcinoma (21.8%). The relative risk of not being useful for diagnosis was higher in small lesions (4,3). Pneumothorax was presented as a complication in two patients. Fine needle aspiration biopsy guided by tomography in lung lesions is a safe procedure, with low complication rate, allowed to safely define the histological characteristics of lung lesions in most lung locations.
RESUMO A biópsia por aspiração com agulha fina guiada por TC tornou-se o padrão mundial como o ponto de partida mais preciso para o comportamento e o prognóstico de lesões sugestivas de câncer de pulmão. Uma intervenção estudo epidemiológico, analítico, quaseexperimental prospectivo, foi realizado em uma coorte de 78 pacientes com lesões sugestivas de câncer de pulmão com o objetivo de avaliar a utilidade da PAAF guiada tomografia computadorizada no diagnóstico histológico de lesões sugestivo de câncer de pulmão no ensino clínico-cirúrgico provincial "Celia Sánchez Manduley" de Manzanillo. Foram incluídos 9 casos com mais de 80 anos, 40% dos pacientes tinham entre 50 e 64 anos, com média de 63,3. O lobo superior direito apresentou 89% das lesões. A distância média entre a pele e o centro do tumor foi de 4,3 cm. A maior positividade foi obtida no lobo superior direito com 82,5%. O diagnóstico histológico evidenciou a presença de processos benignos em 20,7% dos casos. O adenocarcinoma foi responsável por 51,3%, seguido pelo carcinoma de células não pequenas (21,8%). O risco relativo de não ser útil para o diagnóstico foi maior nas lesões pequenas (4,3). Pneumotórax foi apresentado como complicação em dois pacientes. A biópsia aspirativa por agulha fina guiada por tomografia nas lesões pulmonares é um procedimento seguro, com baixa taxa de complicações, que permite definir com segurança as características histológicas das lesões pulmonares na maioria das localizações pulmonares.
