Endoscopic ultrasound (EUS)-guided tissue acquisition has transformed the field by allowing access to pancreatic lesions through fine-needle and biopsy. However, diagnostic accuracy differs based on tumor characteristics and procedural factors. This narrative review explores the nuances of tissue acquisition methods for pancreatic tumors, including factors such as tumor location, size, histological characteristics, and needle selection. It assesses the efficacy of different needle designs and maneuvers, including suction techniques and needle passes. Moreover, the diverse tissue preparation methods, including cytological smear, cell block, and direct histology, are discussed, highlighting the importance of tailored approaches based on tumor characteristics. Additionally, the roles of macroscopic on-site evaluation and rapid on-site evaluation in optimizing specimen adequacy are investigated. Furthermore, percutaneous ultrasound-guided biopsy is considered an alternative approach, particularly in settings where EUS is impractical. Additionally, the review emphasizes the emerging trend of using tissue for genetic testing and molecular analysis, requiring high-quality sample acquisition. Future directions in tissue acquisition techniques and their integration into clinical practice are discussed, providing promising avenues for pancreatic disease diagnosis and treatment.</p>","PeriodicalId":159,"journal":{"name":"Digestive Endoscopy","volume":"37 6","pages":"629-637"},"PeriodicalIF":5.0,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/den.14976","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a case of POET using a novel thin endoscope for an esophageal leiomyoma. A 45-year-old man with moderate dysphagia was referred to our hospital for further examination of a SET in the abdominal esophagus (Fig. 1a). Endoscopic ultrasonography revealed a 30 mm tumor in the second and the third layers, originating from the fourth layer (Fig. 1b). Pathological analysis of fine-needle aspiration specimens identified leiomyoma. POET was performed using a thin therapeutic endoscope with a 7.9 mm diameter (EG-840TP; Fujifilm, Tokyo, Japan) under general anesthesia (Video S1). A 2 cm longitudinal mucosal incision was made using ProKnife (Boston Scientific, Tokyo, Japan) on the proximal side (Fig. 1c). Subsequently, a submucosal tunnel was created from the mucosal entrance to the tumor (Fig. 1d). To avoid injury to the tumor, this endoscope was important to precisely identify the tumor edge in a narrow submucosal space. Clutch Cutter (Fujifilm) and a clip with a thread for traction were used to dissect the muscularis propria, which was continuous with the tumor. We achieved en-bloc enucleation (Fig. 1e). The lesion was removed using an endoscopic net after widening the mucosal entrance (Fig. 1f). We then sutured the mucosal entrance using the reopenable clip-over-the-line method<span>⁴</span> (Fig. 1g). The patient had slight cutaneous emphysema immediately after the procedure but was discharged on postoperative day 5 with a good clinical course. The final pathology was leiomyoma with negative margins (Fig. 1h–k). This thin endoscope has an accessory channel of the same size as that of the conventional endoscope. Therefore, it minimizes the submucosal tunnel using conventional endoscopic devices (Fig. 2).

The incidence rates range from 125 per 100,000 in northern China to 1–1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution. Major modifiable risk factors include tobacco and alcohol consumption, with a synergistic risk increase when combined. Nonmodifiable risk factors include previous diagnoses of head and neck squamous cell carcinoma (H&amp;N SCC), achalasia, and prior radiotherapy. Prevention strategies must be tailored to specific regional burdens to efficiently allocate medical and financial resources. Gastrointestinal endoscopy is crucial in reducing ESCC burden through early detection and characterization of neoplastic changes, such as high-grade dysplasia. Early diagnosis significantly improves survival rates, while endoscopic resection of noninvasive dysplasia can prevent ESCC onset, reducing treatment burden for advanced disease. Postresection surveillance can detect high-risk metachronous lesions. Despite these benefits, endoscopic prevention faces challenges, including the lack of high-level evidence supporting its efficacy, opportunity costs, the need for specialized training and techniques, and the requirement for advanced technology investments.

Conversely, RDI suppressed the yellow tone of fatty tissue and emphasized the blue tone of indigo carmine, which allowed for safe trimming. In submucosal dissection, RDI also improved visibility by reducing lens cloudiness, and the submucosal layer was clearly visible (Fig. 1). We achieved en bloc resection without adverse events (Video S1).

The main hurdles that need to be overcome for such a platform include the requirement of much smaller instruments within the GI lumen, as well as the intuitive movement of these instruments within a tortuous gastrointestinal tract. Existing robotic endoscopic systems could be divided into two main types: completely robotized endoscopic systems and robotic add-on system for existing endoscopic platforms. Among these systems, only a few have successfully reported results of human trials, while the majority of the others still remain at pre-clinical stage.&lt;/p&gt;&lt;p&gt;EndoMaster EASE system is a robotic endoscopic platform that consists of an endoscope mounted to a patient side cart, where two 4 mm robotic instruments (one electrosurgical dissector and one grasper) could be inserted into the target site through the endoscopy channel. The primary endoscopic surgeon controls the robotic instruments from the console unit, with both instruments allowing movement up to 9 Degree of Freedom (DOF). The prototype of the system was first applied in 5 human cases of gastric ESD in 2011 (&lt;span&gt;1&lt;/span&gt;). Following system modification into a fully robotic endoscopic platform, a prospective single arm study was recently reported for 43 patients who underwent colorectal ESD using the system (&lt;span&gt;2&lt;/span&gt;). Technical success was achieved in 86.1% of the patients, with en-bloc resection rate of 94.6% among those with successful procedure. While the results of the trial are encouraging, further questions remain including the need to downsize the system, the cost and benefit when compared with conventional ESD, etc.&lt;/p&gt;&lt;p&gt;EndoQuest Robotics Endoluminal Surgical (ELS) System is another robotic endoscopic platform that has reached the stage of clinical trials. Targeting solely at transanal endoscopic procedure at the sigmoid and rectum, the system consists of a 2.2 cm diameter 4-DOF Steerable Overtube (Previously named as Colubriscope), which allows insertion of one 6 mm flexible endoscope and two 6 mm robotic instruments with 7-DOF.&lt;/p&gt;&lt;p&gt;The system has demonstrated feasibility of partial thickness colorectal resection and suture closure in an ex-vivo animal study (&lt;span&gt;3&lt;/span&gt;). Human clinical trial is currently underway for resection of lesions in sigmoid and rectum, and the results are eagerly awaited.&lt;/p&gt;&lt;p&gt;Flex Robotic System (Medrobotics) utilizes a robotized endoscope with two flexible mechanical arms. The 28 mm diameter flexible robotic endoscope is controlled at the console with a joystick, with two working chan","PeriodicalId":159,"journal":{"name":"Digestive Endoscopy","volume":"36 12","pages":"1394-1397"},"PeriodicalIF":5.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/den.14971","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
