Residual or locally recurrent lesions may occur after endoscopic therapy for epithelial colorectal tumors. Additional mucosal resection is difficult large lesions. Endoscopic submucosal dissection be useful such lesions, but more technically residual/locally than primary This study evaluated the efficacy of in comparison with lesions.This retrospective case-control investigated 34 and 384 treated using dissection. Tumor size, resected specimen procedure duration, en bloc rate, curative...
Abstract Background and study aims Mucosal suturing enables reliable optimal defect closure after endoscopic treatments. We developed investigated the feasibility of hand-suturing (EHS) gastric submucosal dissection (ESD) in porcine vivo models human clinical cases. Patients methods EHS involving continuous mucosal layers using a through-the-scope needle-holder absorbable barbed suture, was performed ESD six live pigs eight consecutive patients. Success rates, adverse events, suture...
Objectives Endoscopic hand suturing (EHS) is expected to decrease the risk of post‐endoscopic submucosal dissection (ESD) bleeding by closing mucosal defects. We investigated efficacy EHS after gastric ESD in patients with antithrombotic agents. Methods In this prospective single‐arm trial, taking agents for cardiovascular disease, arrhythmia, cerebrovascular disease and/or peripheral arterial and having <3‐cm neoplasms were recruited. The defects closed which needle was delivered through...
It is important for endoscopist to diagnose the lesion redness. In this study, we focused on redness of duodenal bulb. We objectively analyzed changes in bulb using linked color imaging (LCI) with chromatic indicators. Seven endoscopists observed white light (WLI) and LCI, evaluated them by visual analogue scale (VAS) degree The difference VAS between WLI LCI was defined as ΔVAS. All images were quantified Comission Internationale de l'Eclariage-L*a*b* space. Values related differences (ΔE*,...
Objectives To verify the efficacy and safety of red dichromatic imaging (RDI) in hemostatic procedures during endoscopic submucosal dissection (ESD). Methods This is a multicenter randomized controlled trial 404 patients who underwent ESD esophagus, stomach, colorectum. Patients received treatments by RDI were defined as group ( n = 204), those white light (WLI) WLI 200). The primary endpoint was shortening hemostasis time. secondary endpoints reduction psychological stress experienced...
<b>Background and study aims:</b> To avoid bacterial contamination tumor seeding during gastrectomy surgery, we developed a nonexposure technique for endoscopic full-thickness resection with laparoscopic assistance. The feasibility safety of nonexposed wall-inversion surgery (NEWS) gastric subepithelial tumors (SETs) were investigated. <b>Patients methods:</b> For protruding SETs ≤ 3 cm in diameter, NEWS was performed the following sequence: seromuscular incision after submucosal injection,...
The effects of patient age on the efficacy eradication treatment for Helicobacter pylori (H. pylori) remain unclear. present study aimed to determine whether affects therapy involving vonoprazan, a novel potassium-competitive acid blocker (PCAB). We reviewed cases 3,261 patients who were administered first-line and second-line H. at Toyoshima Endoscopy Clinic. was clarithromycin amoxicillin combined with proton pump inhibitor (PPI) or PCAB. metronidazole PPI divided into young middle-aged...
Abstract Background and study aims Duodenal endoscopic submucosal dissection (ESD) is still considered technically challenging; however, few studies have objectively analyzed predictors of the technical difficulty. Therefore, aim current was to elucidate difficulty duodenal ESD. Patients methods This a retrospective observational study. From June 2010 2017, total 174 consecutive patients with superficial epithelial neoplasia who underwent ESD were included in this We tried identify for by...
Background Dual red imaging (DRI), a novel image-enhanced endoscopy (IEE) technology, has the potential to improve visibility of blood vessels in deeper tissue using 600 nm and 630 wavelength lights band. Aim To confirm feasibility DRI visualization identify pathologically features visualized by DRI. Methods Study 1: was assessed five observers 137 pairs white light (WLI) images. The scores for thick were measured randomized images compared with scoring template as reference. difference...
