Endoscopic closure of post-endoscopic submucosal dissection (ESD) defects can reduce postoperative adverse events [1]. Innovative techniques such as use an endoloop [2], endoscopic ligation with O-ring [3], and reopenable clip over the line method [4] have recently been developed; however, complexity time-consuming nature procedures remain problematic. We introduce a strategy using new endoclip mantis-like claw (MANTIS Clip; Boston Scientific, Marlborough, Massachusetts, USA) ([Fig. 1]) that...
Abstract Background and Aim Prophylactic closure with the over‐the‐scope clip (OTSC) after endoscopic submucosal dissection (ESD) of superficial non‐ampullary duodenal epithelial tumors (SNADETs) has been reported to reduce postoperative adverse events (AEs). However, there are few evidences regarding AEs‐associated factors long‐term outcomes OTSCs. Methods From January 2011 December 2020, 139 consecutive patients SNADETs who underwent ESD followed by OTSC in five institutions were extracted...
Abstract Background We examined the efficacy of a novel endoscopic ligation technique with O-ring closure (E-LOC) to prevent bleeding after gastric submucosal dissection (ESD) under antithrombotic therapy. Methods This single-center prospective study involved consecutive patients who were taking agents and underwent ESD. E-LOC was performed by anchoring nylon loop hemoclips on both defect edges and/or exposed muscle layer, using band around these deployed clips. The primary outcome post-ESD...
The recently developed endoscopic full-thickness resection technique requires reliable closure. main closure methods are the purse-string suture (PSS) and over-the-scope clip (OTSC) technique; however, basic data on strength of each lacking. This study was performed to compare strengths these two in an ex vivo porcine model.
This study aimed to evaluate the diagnostic utility of ultra-thin endoscope (UTE) for superficial squamous cell carcinoma (SSCC) compared magnifying endoscopy (ME) under narrow-band imaging. Participants underwent endoscopic examination, and images pharyngeal esophageal SCCs, as along with suspicious SSCC lesions, were collected using UTE ME on same day. Three image catalogs (UTE, ME-1, ME-2) created reviewed by three expert endoscopists. ME-1 ME-2 contained images. The primary endpoint was...
Closure of mucosal defects following colorectal endoscopic submucosal dissection (C-ESD) is often performed to prevent post-C-ESD adverse events. However, large defect closure using conventional clips remains technically challenging. Here, we evaluated the feasibility novel endoclip with anchor prongs, called MANTIS Clip (Boston Scientific, Tokyo, Japan), for after C-ESD. This high-volume retrospective study was conducted at a single center. From March until December 2023, consecutive...
Abstract Background and study aims Exposed endoscopic full-thickness resection (EFTR) enables the operator to obtain a sufficient surgical margin. However, insufflation leakage secure closure (EFTC) remain problematic. This aimed evaluate safety feasibility of new exposed EFTR. Patients methods EFTR was performed for 2-cm virtual lesions in different locations upper stomach four dogs. mainly involved half-circumferential endpoint clip-line traction. Pulley traction applied with forward...
To evaluate the efficacy and safety of a grasping-type knife, called Clutch Cutter (CC), for colorectal endoscopic submucosal dissection (C-ESD). This was randomized prospective study. Patients who underwent C-ESD neoplasms >20 mm <50 in size were enrolled, dividing into two groups: ESD using needle type dual knife alone (D-group) circumferential incision followed by CC (CC-group). The primary outcome self-completion rate. secondary outcomes intraoperative complication rate, procedure time,...
The majority of patients with eosinophilic esophagitis (EoE) are likely to have observable features under narrow-band imaging, namely beige mucosa. However, the histological and clinical implications mucosa not been investigated. aim this study was determine whether could serve as an endoscopic marker for predicting active inflammatory sites EoE.We retrospectively analyzed both images biopsied specimens 77 esophageal lesions from 35 consecutive EoE. We divided these into two groups: target...

New configuration of display device having image capture function suitable for LTPS TFT fabrication process is proposed. In this configuration, A/D converter integration to the glass substrate and operation generate higher grayscale bitmap in processing LSI are involved.
Cold forging is a metal forming that which uses localized compressive force at room temperature. During the cold process, tool subjected to extremely high loads and abrasive wear. Lubrication plays an important role in improve product quality life by preventing direct metallic contact. Surface roughness residual stress also greatly affects service of tool. In this study, variations surface roughness, stress, specimen deformation with number cycles were investigated under different...
Introduction: Mucosal defect closure after colorectal endoscopic submucosal dissection (ESD) may prevent post-ESD adverse events. Delayed bleeding is a particular concern in the rectum due to presence of numerous blood vessels. However, rectal often fails thick wall. This study aimed examine feasibility our newly developed ligation with O-ring (E-LOC) for defects ESD. Methods: was prospective observational conducted at single institution. After excluding 2 patients tumors mostly extending...
