Abstract
OBJECTIVES This consensus was developed by the Asian EUS Group (AEG), who aimed to formulate a set of practice guidelines addressing various aspects of endoscopic ultrasound-guided tissue acquisition (EUS-TA). METHODS The AEG initiated the development of consensus statements and formed an expert panel comprising surgeons, gastroenterologists, and pathologists. Three online consensus meetings were conducted to consolidate the statements and votes. The statements were presented and discussed in the first two consensus meetings and revised according to comments. Final voting was conducted at a third consensus meeting. The Grading of Recommendations, Assessment, Development, and Evaluation system was adopted to define the strength of the recommendations and quality of evidence. RESULTS A total of 20 clinical questions and statements regarding EUS-TA were formulated. The committee recommended that fine-needle biopsy (FNB) needles be preferred over conventional fine-needle aspiration (FNA) needles for EUS-TA of subepithelial lesions. For solid pancreatic masses, rapid on-site evaluation is not routinely recommended when FNB needles are used. For dedicated FNB needles, fork-tip and Franseen-tip needles have essentially equivalent performance. CONCLUSION This consensus provides guidance for EUS-TA, thereby enhancing the quality of EUS-TA.

Abstract
A 50-year-old man with a history of total gastrectomy, distal pancreatectomy, splenectomy, and Roux-en-Y reconstruction was admitted to our hospital with a gallbladder tumor that had infiltrated the liver and abdominal wall. Because malignant cells were not collected during the percutaneous biopsy, we planned to perform an endoscopic ultrasound-guided fine-needle biopsy with a 22-G Franseen needle using a forward-viewing echoendoscope. Using intermittent manual compression, the forward-viewing echoendoscope reached the duodenum under fluoroscopic guidance. Endoscopic ultrasound-guided fine-needle biopsy was performed using a 22-G needle and 20-mL syringe and yielded a sufficient specimen with a single puncture. Malignant cells were promptly identified during on-site evaluation. The composition of the specimen (> 20% cancer cells and tissue area exceeding 25 mm2) enabled comprehensive genomic profiling. Subsequently, high-tumor mutational burden was diagnosed based on comprehensive genomic profiling, and pembrolizumab was initiated as a second-line therapy. Even in cases involving Roux-en-Y reconstruction, endoscopic ultrasound-guided fine-needle biopsy using a forward-viewing echoendoscope can result in collection of a high-quality specimen.

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

Application of artificial intelligence to digital-rapid on-site cytopathology evaluation during endoscopic ultrasound-guided fine needle aspiration: A proof-of-concept study. J Gastroenterol Hepatol 2023; 38:883-887. [PMID: 36409289 DOI: 10.1111/jgh.16073] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 11/06/2022] [Accepted: 11/16/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND During endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), cytopathology with rapid on-site evaluation (ROSE) can improve diagnostic yield and accuracy. However, ROSE is unavailable in most Asian and European institutions because of the shortage of cytopathologists. Therefore, developing computer-assisted diagnostic tools to replace manual ROSE is crucial. Herein, we reported the validation of an artificial intelligence (AI)-based model (ROSE-AI model) to substitute manual ROSE during EUS-FNA. METHODS A total of 467 digitized images from Diff-Quik (D&F)-stained EUS-FNA slides were divided into training (3642 tiles from 367 images) and internal validation (916 tiles from 100 images) datasets. The ROSE-AI model was trained and validated using training and internal validation datasets, respectively. The specificity was emphasized while developing the model. Then, we evaluated the AI model on a 693-image external dataset. We assessed the performance of the AI model to detect cancer cells (CCs) regarding the accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS The ROSE-AI model achieved an accuracy of 83.4% in the internal validation dataset and 88.7% in the external test dataset. The sensitivity and PPV were 79.1% and 71.7% in internal validation dataset and 78.0% and 60.7% in external test dataset, respectively. CONCLUSION We provided a proof of concept that AI can be used to replace manual ROSE during EUS-FNA. The ROSE-AI model can address the shortage of cytopathologists and make ROSE available in more institutes.

Abstract
Background: Contrast-enhanced endoscopic ultrasound (CE-EUS) is useful for the differentiation of pancreatic tumors. Using deep learning for the segmentation and classification of pancreatic tumors might further improve the diagnostic capability of CE-EUS. Aims: The aim of this study was to evaluate the capability of deep learning for the automatic segmentation of pancreatic tumors on CE-EUS video images and possible factors affecting the automatic segmentation. Methods: This retrospective study included 100 patients who underwent CE-EUS for pancreatic tumors. The CE-EUS video images were converted from the originals to 90-s segments with six frames per second. Manual segmentation of pancreatic tumors from B-mode images was performed as ground truth. Automatic segmentation was performed using U-Net with 100 epochs and was evaluated with 4-fold cross-validation. The degree of respiratory movement (RM) and tumor boundary (TB) were divided into 3-degree intervals in each patient and evaluated as possible factors affecting the segmentation. The concordance rate was calculated using the intersection over union (IoU). Results: The median IoU of all cases was 0.77. The median IoUs in TB-1 (clear around), TB-2, and TB-3 (unclear more than half) were 0.80, 0.76, and 0.69, respectively. The IoU for TB-1 was significantly higher than that of TB-3 (p < 0.01). However, there was no significant difference between the degrees of RM. Conclusions: Automatic segmentation of pancreatic tumors using U-Net on CE-EUS video images showed a decent concordance rate. The concordance rate was lowered by an unclear TB but was not affected by RM.

Abstract
BACKGROUND AND AIMS Pancreatic neuroendocrine neoplasms (PanNENs), including Grade 1 (G1) or G2 tumors, can have a poor prognosis. This study investigated the value of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for predicting the prognosis of PanNENs. METHODS This single-center, retrospective study included 47 consecutive patients who underwent CH-EUS and were diagnosed with PanNEN by surgical resection or EUS-guided fine needle aspiration between December 2011 and February 2016. Patients were divided into aggressive and non-aggressive groups according to the degree of clinical malignancy. CH-EUS was assessed regarding its capacity for diagnosing aggressive PanNEN, the correspondence between contrast patterns and pathological features, and its ability to predict the prognosis of PanNEN. RESULTS There were 19 cases of aggressive PanNEN and 28 cases of non-aggressive PanNEN. The aggressive group included three G1, four G2, three G3 tumors, three mixed neuroendocrine non-neuroendocrine neoplasms, and six neuroendocrine carcinomas. CH-EUS was superior to contrast-enhanced computed tomography for the diagnosis of aggressive PanNEN (P < 0.001): hypo-enhancement on CH-EUS was an indicator of aggressive PanNEN, with sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 94.7%, 100%, 100%, 96.6%, and 97.9%, respectively. Among G1/G2 PanNENs, cases with hypo-enhancement on CH-EUS had a poorer prognosis than those with hyper/iso-enhancement (P = 0.0009). Assessment of 36 resected specimens showed that hypo-enhancement on CH-EUS was associated with smaller and fewer vessels and greater degree of fibrosis. CONCLUSION Contrast-enhanced harmonic endoscopic ultrasonography may be useful for predicting the prognosis of PanNENs.

Abstract
A comprehensive understanding of gastrointestinal anatomy is essential for performance of any endoscopic procedure. Surgical approaches to therapy have become increasingly common in the past decade, which has resulted in a substantial proportion of patients with surgically altered anatomy who require endoscopy. In parallel with the obesity epidemic, bariatric surgery for obesity management has been widely adopted. In response to these trends, gastroenterologists must become familiar with patient anatomy after these surgical interventions and understand the implications of this altered anatomy on the current array of available endoscopic modalities for diagnosis and therapy. This review describes the range of surgically altered anatomy commonly encountered in the upper gastrointestinal tract. For each foregut location-esophagus, stomach, and small bowel-we describe indications for and specific details of the range of common surgical approaches affecting this regional anatomy. We then provide an endoscopic roadmap through the altered anatomy resulting from these surgical interventions. Finally, we address the impact of postsurgical anatomy on performance of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography, with guidance surrounding how to successfully execute these procedures. Evolution of endoscopic approaches over time might be expected to enhance the safety and efficacy of these interventions in patients with surgically altered anatomy.

Abstract
In recent years, the application of EUS in the diagnosis and treatment has become increasingly popular due to the rapid technological advancements in this field. With the application of new technologies, EUS assistants encounter various problems or “pitfalls” during clinical operations, which may pose challenges to the successful completion of relevant procedures. For example, a needle tip may not be visualized by ultrasonography during EUS-FNA; a stiff fine needle may not be introduced through the working channel of the endoscope in the duodenum, and withdrawal of a guidewire in a needle may be associated with tearing and peeling of the guidewire in EUS-guided biliary drainage. In view of these commonly encountered problems, this article summarizes the countermeasures that EUS assistants can take for EUS-FNA and EUS-guided drainage to improve the efficiency of the procedures and reduce the occurrence of adverse events.

Abstract
Endoscopic ultrasound provides high-resolution, real-time imaging of the gastrointestinal tract and surrounding extramural structures. In recent years, endoscopic ultrasound has played an increasing role as an adjunct or alternative method to conventional surgical therapies. The role of endoscopic ultrasound in diagnosis and management of gastrointestinal malignancy, pancreatic diseases, and biliary diseases continues to evolve. Therapeutic endoscopic ultrasound procedures for a variety of pancreatic and biliary indications shows a high technical and clinical success rate, with low rate of adverse events. Endoscopic ultrasound plays a key role in multidisciplinary management of complex surgical and oncology patients and those with pancreaticobiliary disorders.

Abstract
Background and study aims Little is known about outcomes of biliopancreatic endosonography (EUS) in patients with surgically altered upper gastrointestinal (gastrointestinal) anatomy. We aimed to assess the rate of procedural success and EUS-related adverse events (AEs), according to post-surgical anatomies. Patients and methods Retrospective study including patients with post-surgical altered upper gastrointestinal anatomy who underwent EUS for evaluation of the biliopancreatic region between January 2008 and June 2018 at eight European centers. Results Of 242 patients (162 males, mean age 66.4 ± 12.5), 86 had (35.5 %) Billroth II, 77 (31.8 %) pancreaticoduodenectomy, 23 (9.5 %) Billroth I, 19 (7.9 %) distal esophagectomy, 15 (6.2 %) total gastrectomy, 14 (5.8 %) sleeve gastrectomy, and eight (3.3 %) Roux-en-Y. Sleeve gastrectomy, Billroth I, and pancreaticoduodenectomy were associated with high rates of success (100 %, 95.7 %, and 92.2 %, respectively). Visualization of the head of the pancreas was significantly impacted by total gastrectomy, Billroth II, and Roux-en-Y (success rates 6.7 %, 53.7 %, and 57.1 %, respectively). Examination of the pancreatic body and tail was impaired in esophagectomy and total gastrectomy (82.4 % and 71.4 %, respectively). Technical success and diagnostic accuracy of EUS-guided tissue acquisition (EUS-TA) was 78.2 % and 71.3 % (95 % CI, 60.6-80.5), respectively. Four (1.6 %) AEs were observed: one mucosal tearing in a Billroth II patient, one cardiac arrest in a distal esophagectomy patient, one bleed after EUS-TA in a Billroth I patient, and one acute pancreatitis after EUS-TA in a sleeve gastrectomy patient. Conclusions The yield of bilio-pancreatic EUS is dependent on lesion location and surgery type. Before considering EUS in these patients, one must carefully consider whether the lesion may be approachable by EUS.
