Abstract Objectives Endoscopic ultrasonography (EUS)‐guided radiofrequency ablation has recently been introduced as one of the management strategies for small pancreatic neuroendocrine neoplasms (PNENs). However, prospective data on its safety and efficacy remain limited. Methods This pilot study was conducted at Okayama University Hospital from May 2023 to December 2024. Patients with grade 1 PNENs ≤15 mm, confirmed by EUS‐guided fine‐needle aspiration, were included. The primary endpoint...
Abstract Intrahepatic cholangiocarcinoma has a poor prognosis. In unresectable cases, the survival period is short despite combination therapy with cytotoxic anticancer agents and immune checkpoint inhibitors. The usefulness of inhibitors against malignant tumors microsatellite instability-high (MSI-H) mutations was shown in KEYNOTE158 study; however, data for intrahepatic are insufficient. present case, 65-year-old man lymph node metastasis could not be treated gemcitabine, CDDP, S-1. A...
Abstract A 64‐year‐old woman had undergone subtotal stomach‐preserving pancreaticoduodenectomy for locally advanced pancreatic head cancer. She an uneventful postoperative course with no recurrence. However, approximately 18 months after surgery, she presented recurrent abdominal pain. Although contrast‐enhanced computed tomography radiographs showed internal stent migration to the residual pancreas, dilatation of tail side duct was observed. The impaired considered be cause An attempt...
Background: Bleeding is a serious and frequent adverse event that occurs during after endoscopic papillectomy (EP). Previous studies have highlighted the effectiveness of preventive clipping closure resection site in preventing post-EP bleeding. However, optimal length remained unclear. Objectives: We aimed to clarify at prevent delayed Design: This study was multicenter retrospective cohort study. Methods: retrospectively analyzed patients who were consecutively admitted nine high-volume...
Objective: The sedation method used in double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) varies across countries and between healthcare facilities. No previous studies have compared the effects of different benzodiazepines on during procedures. This study aimed to compare midazolam diazepam DB-ERCP outcomes. Methods: retrospective cohort analyzed consecutive patients who underwent January 2017 February 2024. A total 203 were sedated with (n = 94) or 109) analyzed....
Background Acute pancreatitis is a major adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Rectal administration non‐steroidal anti‐inflammatory drugs (NSAIDs) decreases the incidence post‐ERCP (PEP). However, efficacy low dose rectal NSAIDs for preventing PEP remains controversial. Methods We performed retrospective study 301 patients with native papilla and body weight <50 kg who underwent ERCP between September 2010 October 2019. After July 2016, 25 mg diclofenac...
Background: Endoscopic retrograde cholangiopancreatography (ERCP) for extraction of common bile duct (CBD) stones in patients with Roux-en-Y gastrectomy (RYG) remains technically challenging. Methods: Seventy-nine RYG (median 79 years old) underwent short-type double-balloon enteroscopy-assisted ERCP (sDBE-ERCP) CBD at three referral hospitals from 2011–2020. We retrospectively investigated the treatment outcomes and potential factors affecting complete stone extraction. Results: The initial...
Background: Drainage exceeding 50% of total liver volume is a beneficial prognostic factor in patients with unresectable malignant hilar biliary obstruction (UMHBO). However, it unclear what threshold percentage drained (‘liver drainage rate’) significantly improves survival UMHBO who received systemic chemotherapy. Objectives: We aimed to assess the optimal rate that receiving chemotherapy using three-dimensional (3D)-image analyzer. Design: This study was single-center retrospective cohort...
Abstract Background Pancreatic juice cytology (PJC) is a tool for diagnosing malignant intraductal papillary mucinous neoplasm (IPMN); however, the accuracy insufficient using conventional method. Liquid-based (LBC) improves cell recovery rate, and almost all cells can be evaluated. We evaluated efficacy of PJC with LBC IPMN. Methods retrospectively analyzed 90 patients suspected IPMN who underwent before pancreatectomy. smear methods was conducted in 52 (between June 2003 to December 2011)...
A centrifugal pump that employs a bearingless motor with 5-axis active control has been developed. In this paper, novel canned is proposed, and differences from the conventional structure are explained. key difference between proposed pumps use of passive magnetic bearings; in pump, amount permanent magnets (PMs) reduced by 30% length rotor shortened. Despite decrease total volume PMs, can generate large suspension forces high torque compared design bearings. addition, levitation rotation...
Background/Aims: Bilateral endoscopic drainage with self-expanding metallic stent (SEMS) can be used to effectively manage hilar malignant biliary obstruction.However, the benefits of using a trisegment method remain unknown. Methods:This study retrospectively reviewed data 125 patients Bismuth type IIIa or IV unresectable strictures who underwent bilateral SEMSs at four tertiary centers.The were divided into and groups for comparison.The primary endpoint was patency secondary endpoints...
Objective Strict follow-up is recommended for branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) to avoid missing the development of high-risk stigmata (HRS) at a premalignant stage. This study explored risk factors associated with HRS during follow-up. Methods We performed retrospective analysis 283 patients BD-IPMN, treated Okayama University Hospital in Japan between January 2009 and December 2016. Only imaging studies indicative classical features BD-IPMN without followed...
Abstract Background The sedation method used during double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) differs among countries and/or facilities, and there is no established method. This study aimed to evaluate the efficacy of non-anesthesiologist-administered propofol (NAAP) using a target-controlled infusion (TCI) system DB-ERCP. Methods retrospective was conducted between May 2017 December 2020 at an academic center. One hundred fifty-six consecutive patients who...
Duodenal wall perforation by a dislocated biliary stent placed for structure is rare but can be life-threatening. There are few reports on the management of stent-related duodenal perforation.Three cases included in this study had undergone endoscopic retrograde cholangiopancreatography with placement plastic stricture. Two symptoms (fever or abdominal pain), while other case showed no symptom after placement.Dislocation stents was revealed computed tomography images. patients were diagnosed...
<title>Abstract</title> <bold>Objectives:</bold> This study aimed to assess the correlation between platelet aggregation levels measured using aggregometry and incidence of postprocedural bleeding after endoscopic submucosal dissection (ESD) in patients with gastric neoplasms receiving antiplatelet agents. <bold>Methods:</bold> Between April 2013 March 2020, 69 (47 men, 22 women) underwent ESD for 82 lesions while continuously Platelet were assessed before by an aggregometer-based...
We investigated an electrochemical separation method for anodic aluminum oxide (AAO) films possessing thicker barrier layers by electrolysis in sodium chloride (NaCl) and ethylene glycol (EG) solution subsequent fabrication of through-hole AAO membranes immersion phosphoric acid (H 3 PO 4 ) solution. The with different layer thicknesses were formed on the surface anodizing sulfuric, oxalic, H solutions at up to 130 V. AAO-covered specimens immersed NaCl/EG solution, then constant voltage 10...
