Artificial Intelligence in Endoscopic Ultrasonography-Guided Fine-Needle Aspiration/Biopsy (EUS-FNA/B) for Solid Pancreatic Lesions: Opportunities and Challenges. Diagnostics (Basel) 2023; 13:3054. [PMID: 37835797 PMCID: PMC10572518 DOI: 10.3390/diagnostics13193054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/06/2023] [Accepted: 09/06/2023] [Indexed: 10/15/2023] Open
Abstract
Solid pancreatic lesions (SPLs) encompass a variety of benign and malignant diseases and accurate diagnosis is crucial for guiding appropriate treatment decisions. Endoscopic ultrasonography-guided fine-needle aspiration/biopsy (EUS-FNA/B) serves as a front-line diagnostic tool for pancreatic mass lesions and is widely used in clinical practice. Artificial intelligence (AI) is a mathematical technique that automates the learning and recognition of data patterns. Its strong self-learning ability and unbiased nature have led to its gradual adoption in the medical field. In this paper, we describe the fundamentals of AI and provide a summary of reports on AI in EUS-FNA/B to help endoscopists understand and realize its potential in improving pathological diagnosis and guiding targeted EUS-FNA/B. However, AI models have limitations and shortages that need to be addressed before clinical use. Furthermore, as most AI studies are retrospective, large-scale prospective clinical trials are necessary to evaluate their clinical usefulness accurately. Although AI in EUS-FNA/B is still in its infancy, the constant input of clinical data and the advancements in computer technology are expected to make computer-aided diagnosis and treatment more feasible.

THE TURKISH JOURNAL OF GASTROENTEROLOGY : THE OFFICIAL JOURNAL OF TURKISH SOCIETY OF GASTROENTEROLOGY 2023; 34:611-617. [PMID: 37078203 PMCID: PMC10441164 DOI: 10.5152/tjg.2023.22380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 09/12/2022] [Indexed: 04/21/2023]
Abstract
BACKGROUND The aim of the study is to evaluate the extent to which patients acquired necessary knowledge about pancreatic endoscopic ultrasound-guided fine needle aspiration and assess what should be more focused on in the informed consent process. METHODS Adult patients enrolled in this study had pancreatic lesions confirmed by regular imaging and planned to undergo the first pancreatic endoscopic ultrasound-guided fine needle aspiration. These patients were asked to complete a questionnaire, including indications, possible results, downstream events, the risk for false-negative and malignant lesions, and so on. Then we conducted a longterm follow-up of these patients to obtain the final results. RESULTS Most people (94.25%) correctly recognized that the indication of pancreatic endoscopic ultrasound-guided fine needle aspiration was to exclude malignant lesions. Almost all patients knew that the results could be benign or malignant, while the number of people who were aware of non-diagnostic (22%), indeterminate (18%) outcomes, and the possibility of further testing (20%) after the endoscopic ultrasound-guided fine needle aspiration has decreased significantly. Finally, we got that the false-negative rate and percentages of malignancy were 17.81% and 83.91%, while 98% of participants did not recognize that there is a false-negative risk of endoscopic ultrasound-guided fine needle aspiration and more than 2/3 of participants did not know how much risk they might have for malignant lesions. CONCLUSIONS A high proportion of patients who received endoscopic ultrasound-guided fine needle aspiration could identify the indication for this procedure but remained unaware of possible outcomes, downstream events, especially the risk for false-negative and malignant lesions. It is necessary to improve the quality of dialogue between clinicians and patients, and the information about the risk of false-negative and malignancy may need to be emphasized in the informed consent process.

The Rate of Avoidable Pancreatic Resections at a High-Volume Center: An Internal Quality Control and Critical Review. J Clin Med 2023; 12:jcm12041625.

Abstract
BACKGROUND The incidence of benign diseases among pancreatic resections for suspected malignancy still represents a relevant issue in the surgical practice. This study aims to identify the preoperative pitfalls that led to unnecessary surgeries at a single Austrian center over a twenty-year period. METHODS Patients undergoing surgery for suspected pancreatic/periampullary malignancy between 2000 and 2019 at the Linz Elisabethinen Hospital were included. The rate of "mismatches" between clinical suspicion and histology was considered as primary outcome. All cases that, despite that, fulfilled the indication criteria for surgery were defined as minor mismatches (MIN-M). Conversely, the true avoidable surgeries were identified as major mismatches (MAJ-M). RESULTS Among the 320 included patients, 13 (4%) presented with benign lesions at definitive pathology. The rate of MAJ-M was 2.8% (n = 9), and the most frequent causes of misdiagnoses were autoimmune pancreatitis (n = 4) and intrapancreatic accessory spleen (n = 2). In all MAJ-M cases, various mistakes within the preoperative workup were detected: lack of multidisciplinary discussion (n = 7, 77.8%); inappropriate imaging (n = 4, 44.4%); lack of specific blood markers (n = 7, 77.8%). The morbidity and mortality rates for mismatches were 46.7% and 0. CONCLUSION All avoidable surgeries were the result of an incomplete pre-operative workup. The adequate identification of the underlying pitfalls could lead to minimize and, potentially, overcome this phenomenon with a concrete optimization of the surgical-care process.

Abstract
BACKGROUND Histologic confirmation before pancreaticoduodenectomy (PD) for suspected pancreatic cancer is often performed. We assessed the yield of preoperative biopsy in these patients considering the associated complications. METHODS We retrospectively evaluated 216 patients that underwent PD for suspected carcinoma (CA) between 2012 and 2018. Post procedure complications and delay in surgery were assessed, as well as the postoperative diagnosis in relation to preoperative parameters. RESULTS Preoperative biopsy was performed in 142 patients (65.7%). Pathologic findings suggestive of CA were found in 106 (74.6%), while benign histology was found in 23 (16.1%), and non-diagnostic findings in 12 (8.4%). Seventy-four patients (34.3%) were operated without a preoperative biopsy. The time from diagnosis to surgery was significantly prolonged in those that underwent biopsy compared to patients that were taken straight to surgery (40±14 versus 18±15 days, P<0.001), and 18 patients (12.6%) suffered from clinically significant post procedure complications. Patients with a preoperative biopsy suggestive of CA, and those that were operated without a preoperative histologic confirmation had comparable rates of CA as a final pathological diagnosis (95.2% and 94.5%, respectively). Nevertheless, in patients with a benign or a non-diagnostic biopsy, the rates of pathologic diagnosis of CA were 69.6% and 73.6% respectively. Elevated levels of CA19-9 and a positive preoperative biopsy were associated with a final pathology of CA. CONCLUSIONS Preoperative histology is not uniformly required in patients with suspected pancreatic cancer. If preoperative biopsy is performed, benign histology does not rule out cancer but warrants additional evaluation prior to surgery.

Huang J, Liang Y, Xu L, Hu D. Diagnostic efficacy of different pathologic methods for assessing tissue obtained by endoscopic ultrasound-guided fine needle aspiration: a prospective study. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2021; 14:34-44.

Abstract
AIMS The best method for processing specimens by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has not been standardized and varies considerably between medical centers. The purpose of this study is to explore whether a combination of histologic and cytologic methods can increase the diagnostic efficacy of EUS-FNA in solid lesions around the digestive tract. METHODS We recruited 52 patients (65 cases total) with solid lesions around the digestive tract who underwent EUS-FNA as performed by the same endoscopic physician from December 2016 to January 2018. All the EUS-FNA specimens were processed by conventional smear cytology (CS), liquid-based cytology (LBC), cell block (CB), and histopathology. All the pathologic results were tracked to investigate the diagnostic value of the methods. RESULTS Fifty-three malignant lesions and 12 benign lesions were analyzed. The diagnostic accuracy levels of the CS, LBC, CB, and histopathology were 96.9%, 89.2%, 91.9%, and 48.1%, respectively. CS had a higher diagnostic accuracy than CB (P < 0.05) and LBC (P < 0.05). The cytologic methods had a significantly higher diagnostic accuracy than histopathology (P < 0.05). The combined diagnostic accuracy of all the methods was 100%. The diagnostic sensitivities of the CS, LBC, CB and histopathology were 96.2%, 86.8%, 90.4%, and 37.2%, respectively, and the diagnostic specificity of each of the four methods was 100%. CONCLUSIONS Different pathological methods can compensate for one another, substantially improving the overall positive detection rate of EUS-FNA. Combining cytology and histology can contribute additional diagnostic efficacy to EUS-FNA in solid lesions around the digestive tract.

Slow-pull and different conventional suction techniques in endoscopic ultrasound-guided fine-needle aspiration of pancreatic solid lesions using 22-gauge needles. World J Gastroenterol 2016; 22:8790-8797. [PMID: 27818594 PMCID: PMC5075553 DOI: 10.3748/wjg.v22.i39.8790] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2016] [Revised: 09/19/2016] [Accepted: 09/28/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the cytological diagnostic capacity and sample quality of the slow-pull technique and compare them with different suction techniques.
METHODS From July 2010 to December 2015, 102 patients with pancreatic solid lesions who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with 22-gauge needles were retrospectively evaluated. EUS-FNA diagnosis was based on a cytological examination, and final diagnosis was based on a comprehensive standard of cytological diagnosis, surgical pathology and clinical or imaging follow-up. Cytological specimens were characterized for cellularity and blood contamination. The cytological diagnostic capacity and sample quality of the slow-pull technique and suction techniques with 5-mL/10-mL/20-mL syringes were analyzed.
RESULTS Of all of the EUS-FNA procedures, the slow-pull technique and suction techniques with 5-mL/10-mL/20-mL syringes were used in 31, 19, 34 and 18 procedures, respectively. There were significant differences between these four suction techniques in terms of cytological diagnostic accuracy (90.3% vs 63.2% vs 58.8% vs 55.6%, P = 0.019), sensitivity (88.2% vs 41.7% vs 40.0% vs 36.4%, P = 0.009) and blood contamination (score ≥ 2 for 29.0% vs 52.6% vs 70.6% vs 72.2%, P = 0.003). The accuracy and sensitivity of the slow-pull technique were significantly higher than those of the suction techniques using 5-mL (P = 0.03, P = 0.014), 10-mL (P = 0.005; P = 0.006) and 20-mL syringes (P = 0.01, P = 0.01). Blood contamination was significantly lower in the slow-pull technique than in the suction techniques with 10-mL (P = 0.001) and 20-mL syringes (P = 0.007).
CONCLUSION The slow-pull technique may increase the cytological diagnostic accuracy and sensitivity with slight blood contamination during EUS-FNA when using 22-gauge needles for solid pancreatic masses.

Abstract
Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) have much in common, including their main indications (biliopancreatic disorders), powerful therapeutic capacities and a steep learning curve. Over the years they have evolved from novel diagnostic procedures to interventional therapeutic techniques, but along different paths (different scopes or devices and endoscopists specializing exclusively in one or the other technique). However, EUS has gradually developed into a therapeutic technique that requires skills in the use of ERCP devices and stents, leading some ERCP specialists to explore the therapeutic potential of EUS. The corresponding literature, which has grown exponentially, includes recent experiments on combining the two techniques, which have gradually come to be used in routine care in a number of centers, with positive technical, clinical and financial outcomes. We review EUS and ERCP as individual or combined procedures for managing biliopancreatic disorders.

Abstract
In the elderly patients, where biopsy-induced complications could outweigh the benefit, the identification of pancreatic masses is generally referred to as a synonymous of pancreatic cancer and patients are dismissed with no further options than palliative and supportive care. Notwithstanding, not all pancreatic tumors are cancers and therefore alternative diagnoses need to be investigated, especially when patients are unfit for invasive diagnostic procedures. Here, we report a case of an aged patient that was admitted to an internal medicine division for a previously diagnosed pancreatic cancer. The reassessment of the diagnosis has allowed identifying the pancreatic mass as a manifestation of focal pancreatitis in the context of an IgG4-related disease. Accordingly, patient was treated with steroids with rapid clinical improvement. This clinical case suggests that autoimmune diseases should always be considered in the differential diagnosis of pancreatic masses of the elderly.
