Abstract
INTRODUCTION Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is frequently used to risk-stratify pancreatic cystic lesions (PCLs). Rising PCL incidence and developments in tissue acquisition and specimen analysis necessitate updated appraisal of EUS-FNA safety, particularly the risk of postprocedure pancreatitis, the most common EUS-FNA-related adverse event. Our systematic review aims to accurately quantify the risk of EUS-FNA-related pancreatitis to best inform decisions regarding EUS-FNA's optimal role in PCL workup. METHODS We performed systematic searches in 4 databases from inception to April 2024 for original English-language studies investigating EUS-FNA-related pancreatitis. We extracted data on demographics and EUS-FNA-related pancreatitis risk, severity, and risk factors. These were meta-analyzed through the DerSimonian Laird Method using a random-effects model. Meta-regression of pancreatitis risk was performed to delineate associations with clinical and procedural characteristics. RESULTS Sixty-four studies comprised 8,086 patients and reported 110 EUS-FNA-related pancreatitis events. Pooled risk of EUS-FNA-related pancreatitis was 1.4% (95% confidence intervals, -0.8% to 3.5%; I2 = 0.00), which was predominantly of mild severity (67%) and uniformly nonfatal. Pancreatitis risk lacked significant association with sample size, age, sex, cyst size, needle caliber, or passes, although we noted trends toward higher risk in studies published after 2015, those using higher gauge needles (19 G vs 22 G/25 G), and those performing EUS-guided through-the-needle biopsy. DISCUSSION We note with high certainty that pancreatitis after EUS-FNA of PCLs is infrequent and mild in severity with no mortality in the included cohort. EUS-guided through-the-needle biopsy may serve as a significant risk factor for EUS-FNA-related pancreatitis risk; however, further studies are needed to delineate other predisposing characteristics.

Bueno A, Felipe-Silva A, Saieg M. Small biopsies for pancreatic lesions: Is there still room for fine needle aspiration? Cytopathology 2024; 35:70-77. [PMID: 37905686 DOI: 10.1111/cyt.13323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 10/08/2023] [Accepted: 10/13/2023] [Indexed: 11/02/2023]
Abstract
Pancreatic carcinoma is an aggressive tumour with increasing incidence in both sexes worldwide. Early detection is, therefore, essential for patient management. A recent advancement involves the utilization of larger, thicker gauge needles, which enable the collection of core-type biopsies (FNB). Here, we investigated the role of fine needle aspiration and cytopathology in the diagnostic workflow of pancreatic lesions. A search query was designed to search for articles in the PubMed database comparing FNA and FNB for biopsy of pancreatic lesions, and detailed data were extracted from selected studies. Statistical analyses were performed using the R package meta version 6.2. Twenty-one studies made the final cut for data extraction. Overall, median age was 64.3 years (±6.1; 47.6-71.5), male: female proportion 53.9 (±11.3; 27.6-67.4), lesion size 3.1 cm (±0.5; 1.9-4.2 cm) and percentage of malignant cases 78.3% (±26.8; 2.1-100). FNA and FNB diagnostic yield was 85.8% (±10.3; 70.0-100.0) and 89.2% (±7.7; 70.0-98.6), respectively. Average accuracy was 89.5% (±11.7; 63.0-100.0) for FNA and 90.8% (±7.1; 77.0-100.0) for FNB. Adverse effects rate was 1.0% (±1.3; 0-4.3) for FNA and 2.2% (±4.4; 0-16.1) for FNB. None of the selected variables had a significant statistical difference between both methods. FNA and FNB perform similarly for diagnostic material acquisition in pancreatic lesions. The best outcome comes from the association of both techniques, emphasizing the value of combining cytological and histological morphology for the most accurate analysis.

Abstract
Background and study aims There are rare data on the usefulness of endosonography-guided tissue acquisition (EUS-TA) in patients with pancreatic cystic lesions (PCLs). This study aimed to determine the accuracy of EUS-TA with ProCore 20G (PC20) for differentiating between mucinous neoplasia (MN) and non-MNs (n-MN) and identifying malignant PCLs, as well as its adverse events (AEs) in patients with PCLs without a classificatory diagnosis by imaging exams. Patients and methods In this observational, retrospective, single-center study, all patients with PCL who underwent EUS-TA due to diagnostic doubts in imaging studies were consecutively recruited from June 2017 to December 2021. The outcomes were to determine the diagnostic accuracy of EUS-TA with PC20 for differentiating between MN and n-MN, identifying malignant PCLs, and the AEs. Results Herein, 145 patients underwent EUS-TA, with 83 women (57.2%) and a mean age of 62.2 years. The mean size was 2.3 cm, with 81 patients (77.9%) having a PCL < 3.0 cm. The final diagnosis was made by EUS-TA (n = 81), surgery (n = 58), and follow-up (n = 6). The sensitivity, specificity, positive and negative predictive values, and accuracy for differentiating between MNs and n-MNs and identifying malignant PCLs were 92.6%, 98.4%, 98.7%, 91.3%, and 95.2% (kappa=0.9), and 92%, 99.2%, 95.8%, 98.3%, and 97.9% (kappa = 0.93), respectively. The AE rate was 2.7%, with no deaths in this cohort. Conclusions EUS-TA with PC20 has high accuracy and technical success with a low AE rate for PCL diagnosis.

Abstract
Antibioprohylaxis (ABP) for pancreatic cystic lesion is still a debated clinical indication. Although professional societies guidelines still recommend ABP in endoscopic ultrasound-fine needle aspiration (EUS-FNA) for pancreatic cystic lesions (PCL), this standard of care recommendation was based on old and weakly planned studies with a small number of patients. Herein, in this work, we provide a critical review with pooled data analysis of the available literature. Overall, the studies reported are weak and limited with small number of patients, the absence of exact definition of infection and the heterogenicity of the type and the duration of the ABP used. Pooled data analysis showed that the effect of ABP on the rate of cyst infection was not significant (OR 0.56, 95% CI 0.17-1.2), with no significant heterogenicity between the results of the studies reviewed and reported (as assessed by Breslow Day test for homogeneity of OR's [P = 0.15]). The pooled infection rate without ABP was 0.89% and 0.36% in the ABP group. Moreover, according to the pooled data infection rate, sample size calculation demonstrated that 6954 patients are needed to show superiority of ABP, with a number needed to treat of 179 patients to prevent single infection. However, through the literature only six studies (1660 patients) reported the cyst infection rate among ABP versus control, making these results scarce and biased by a small number of patients. Therefore, we suggest the need to revise the guidelines, until performing well organized large international study to solve this controversy.

Abstract
Background and Objectives: Pancreatic EUS-guided fine needle biopsy (EUS-FNB) is increasingly used. Accuracy of EUS-FNB, particularly for benign diseases, utility of additional EUS-FNB if malignancy is suspected but initial diagnosis is inconclusive, and complication rate are not fully elucidated. We evaluated operating characteristics of EUS-FNB overall and for different diagnostic categories, value of additional EUS-FNB if malignancy is suspected but initial diagnosis is inconclusive, and frequency and type of complications. Methods: A retrospective tertiary single-center study including 852 consecutive pancreatic SharkCore EUS-FNBs from 723 patients between 2015 and 2020. EUS-FNB diagnoses were applied according to Papanicolaou Society's system and each category was further subcategorized. Results: Sufficient tissue cylinders for a histologic diagnosis were obtained in 93.4% (796/852). Accuracy was overall, for malignant, and benign entities 85.6% (confidence interval [CI]: 83.2%–87.9%), 88.3% (CI: 85.9%–90.4%), and 94% (CI: 92.2%–95.5%). Sensitivity and accuracy of EUS-FNB for autoimmune pancreatitis (AIP) (n = 15) was 83.3% (CI: 58.6%–96.4%) and 99.2% (CI: 98.3%–99.7%). Of patients in whom malignancy was suspected but initial EUS-FNB diagnosis was inconclusive, 7.3% (53/723) underwent one or two additional EUS-FNBs, and in 54.7% (29/53) of these, a malignant diagnosis was established. The frequency of hospitalization following EUS-FNB was 4.7%, with 0.2% (n = 2) incidents needing active intervention. Conclusions: We found a high accuracy of pancreatic EUS-FNB across all diagnostic categories including rare entities, such as AIP. In patients with a clinical suspicion of malignancy, additional EUS-FNB resulted in a conclusive diagnosis in more than half of cases. Complications necessitate hospitalization in almost 5%, but the majority are self-limiting.

Abstract
OBJECTIVES The yield of genetic testing of main pancreatic duct (MPD) fluid collected during endoscopic retrograde cholangiopancreatography (ERCP) versus endoscopic ultrasound-guided fine-needle aspiration is unclear. METHODS Consecutive MPD fluid samples obtained by endoscopic ultrasound/ERCP with DNA profiling were reviewed, excluding specimens designated "no amplification." Invasive disease included invasive cancer or malignant cytology. RESULTS One hundred ten samples from 109 patients who underwent ERCP (n = 32) or endoscopic ultrasound-guided fine-needle aspiration (n = 78) were analyzed (2007-2018). Leading indications were dilated MPD and suspected intraductal papillary mucinous neoplasm. Elevated DNA quantity, KRAS, loss of heterozygosity (LOH), and GNAS mutations occurred in 61.5%, 25.5%, 16.4%, and 8.7% of samples, respectively. Elevated DNA quantity occurred more frequently in ERCP samples (84.4% vs 51.9%, P = 0.002); other mutation yields were similar (P > 0.05). Invasive pathology (P = 0.032) was associated with LOH in the subset of patients who underwent surgery (n = 44). Adverse events occurred more frequently after ERCP (28.1% vs 9.0%, P = 0.016). CONCLUSIONS Endoscopic MPD fluid sampling may yield genetic data to improve diagnosis and risk stratification. In our surgical cohort, LOH was the sole predictor of invasive pathology. Endoscopic ultrasound-guided fine-needle aspiration of MPD fluid, when possible, is preferred because of superior safety profile.

Abstract
BACKGROUND Cystic lesions of the pancreas (PCLs) may be inflammatory or proliferative and making an accurate and timely pre-operative diagnosis remains a significant clinical challenge. This is principally due to the heterogeneity of the pathological processes involved. PCLs constitute an entity with diverse histology and although infrequent, the possible potential for malignant transformation of these lesions and the opportunity for curative surgery mandates that our diagnostic approaches are up to date and evidence based. In addition, improved diagnostic accuracy is crucial to prevent unnecessary surgical procedures with the inevitable associated morbidity. METHODS This narrative review examines the current diagnostic benchmarks and identifies novel diagnostic techniques that warrant further consideration, a number of which are beginning to be included in routine clinical practice when these PCLs are being investigated. A computerized search was made of MEDLINE, EMBASE and PubMed using the search words 'diagnostic approaches to pancreatic cystic lesions'. All relevant articles in English language or with an English abstract were retrieved and additionally cross referenced. CONCLUSION The increasing accuracy of available imaging techniques together with the wider availability of endoluminal ultrasound and the development of additional novel methods to assess PCLs presents an opportunity to significantly improve the pre-operative diagnosis rate. This is essential to classify the type of PCL and hence guide the management particularly with lesions where there is a likelihood of progression to more serious pathology. We have highlighted the need for a comprehensive and standardized algorithm for the diagnosis and management of PCLs.

Abstract
Background. Endoscopic ultrasound (EUS) and fine-needle aspiration (FNA) are commonly used for assessing pancreatic lesions. This study aimed to evaluate the diagnostic yield and accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in a single tertiary institution. Methods. Consecutive patients who underwent EUS-FNA of the pancreas at Queen Mary Hospital, Hong Kong, from January 2015 to March 2016 were retrospectively reviewed. Endoscopic findings and FNA results were analysed. For patients who subsequently underwent surgical resection of pancreatic lesion, EUS-FNA diagnoses were compared to histopathological findings of surgical specimens to determine its diagnostic accuracy. Results. One hundred twelve EUS-FNA were performed in 99 patients within the study time period and were included for analysis. Sixty-six (66.7%) pancreatic lesions were solid in nature and 33 (33.3%) were cystic. The overall diagnostic yield of EUS-FNA was 70.5% (n = 79). On multivariate analysis, more passes of needle were associated with a higher diagnostic yield (odds ratio = 2.000, P = .049). 57.1% (n = 64) of EUS-FNA results had an impact on management. Sixteen patients with diagnostic EUS-FNA subsequently underwent surgery for resection of the pancreatic lesion. Upon correlation to the histopathological findings of surgical specimens, there were 12 true-positive, 2 true-negative, 0 false-positive, and 2 false-negative cases. Sensitivity was 85.7%, specificity was 100%, positive predictive value was 100%, and negative predictive value was 50%. The diagnostic accuracy of EUS-FNA was 87.5%. Conclusion. EUS-FNA is accurate and reliable for diagnosing pancreatic lesions.

Abstract
Endoscopic ultrasonography (EUS) is a modality with high spatial resolution that enables comprehensive observation of the entire pancreas and plays an important role in the diagnosis of pancreatic lesions. Recent advances in diagnostic imaging methods such as ultrasound, computed tomography, and magnetic resonance imaging have increased the incidental detection of pancreatic cystic lesions (PCLs). EUS has been recognized as an essential diagnostic method for the detection and evaluation of PCLs. EUS has two important roles: as a detailed (high-resolution) imaging diagnostic method and as an approach for collecting cyst fluid content by EUS-guided fine needle aspiration for pathological diagnosis or biomarker evaluation. Furthermore, in recent years, the usefulness of contrast-enhanced EUS for the differential diagnosis of PCLs or evaluation of grade of malignancy, and a novel imaging technique called needle-based confocal laser endomicroscopy to observe intraductal structures through a needle, has been reported. An understanding of the morphological characteristics of PCLs depicted by ultrasound imaging and of the benefits and limitations of EUS diagnosis in daily practice is needed.

Abstract
AIM To evaluate the clinical utility of computed tomography (CT)-guided percutaneous biopsies of suspect pancreatic lesions regarding safety, efficiency, radiation dose, intervention time, diagnostic yield, and complications. MATERIALS AND METHODS Between 2015 and 2018, 48 patients (18 female, 30 male; mean age: 64.2 years) with suspect pancreatic lesions underwent CT-guided percutaneous biopsy. Ultrasound-guided biopsy of all lesions was not possible or without any result. CT-guided interventions were compared according to the following intervention parameters: radiation dose, procedure duration, number of needle correction scans. Evaluation criteria included technical success as well as major and minor complications according to the Society of Interventional Radiology. RESULTS Biopsies were performed successfully in 100% of patients. No major side effects occurred during intervention. As a minor complication, 29.2% showed focal haemorrhage. Seventy-seven percent of lesions had a malignant appearance, and benign inflammatory lesions were found in 23%. The mean size of the target lesions was 2.9 cm (range: 0.7-2.3 cm). The mean target access path within the patient was 8 cm (range: 3-14 cm). The duration to completion was 12 minutes (range: 3 minutes 30 seconds to 30 minutes). The dose-length product of the intervention was 89.5 mGy·cm (range: 11-350 mGy·cm). The average number needle correction scans was 31.1 (range: 6-36). CONCLUSION CT-guided biopsy of suspect pancreatic lesions is an efficient and safe method. It can be performed within short intervention times and low radiation exposure for differentiation of unclear lesions.
