Five cases of ectopic liver, two retro-peritoneal cavity and three gallbladder, a case accessory lobe the are reported. One theses with liver was accompanied by multiple cysts kidney, biliary microhamartoma, which observed laparoscopically on surface main histologically proven in liver.
Background and Aim Underwater endoscopic mucosal resection ( UEMR ) has been reported as an alternative to conventional EMR for superficial non‐ampullary duodenal epithelial tumors SNADET ). However, the detailed outcomes are unclear. This study aimed compare clinical between <20 mm. Patients methods is a retrospective observational using prospective maintained database. From November 2017 December 2018, 104 consecutive cases of attempted mm were prospectively allocated. A total 240...
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...
There are no reports on detailed endoscopic diagnosis of superficial non‐ampullary duodenal epithelial tumors (SNADET) except for relatively small case series. Herein, we conducted a prospective observational study to investigate the relationship between findings and histopathological SNADET. A total 163 SNADET diagnosed using magnified examination with image‐enhanced endoscopy (IEE‐ME) were prospectively registered in this study. We investigated location, size, macroscopic type, color,...
ABSTRACT Background Clinically significant serrated polyps (CSSPs) are defined as sessile lesions (SSLs), SSLs with dysplasia, traditional adenomas (TSAs), hyperplastic (HPs) ≥ 10 mm, and HPs 6 mm in the proximal colon. further classified microvesicular (MVHPs) goblet cell‐rich (GCHPs). Among CSSPs, were categorized into clinically MVHPs (CS‐MVHPs) GCHPs (CS‐GCHPs). This study compares characteristics of CS‐MVHPs, CS‐GCHPs, SSLs. Methods included patients who underwent colonoscopy at...
INTRODUCTION: Underwater endoscopic mucosal resection (UEMR) and cold snare polypectomy (CSP) are novel procedures for superficial nonampullary duodenal epithelial tumors (SNADET). However, consensus on how to use both appropriately has not been established. In this study, we evaluated treatment outcomes of procedures, including resectability. METHODS: single-center randomized controlled study conducted between January 2020 June 2022, patients with SNADET ≤12 mm were randomly allocated UEMR...
Abstract Background and study aims Colorectal endoscopic submucosal dissection (ESD) remains challenging for novice endoscopists. Not only the underwater conditions but also active use of water pressure with method (WPM) can help widen layer. This aimed to clarify usefulness WPM in colorectal ESD, especially Methods was ex vivo enrolled three novices. Each endoscopist performed conventional ESD (C-ESD) (WPM-ESD) 10 times on an excised bovine rectum. The treatment outcomes were compared...
Objectives Endoscopic papillectomy (EP) is a low‐invasive treatment for duodenal tumors including papilla. The limit of lesion size and local recurrence have been issues in EP. We developed endoscopic submucosal dissection (ESD) the papilla (ESDIP: ESD papilla) to overcome problems. aim this study was evaluate feasibility ESDIP. Methods included patients who underwent ESDIP from August 2010 January 2024 study. evaluated retrospective characteristics lesions, clinical results retrograde...
Background/Aims: Although colonic diverticular bleeding (CDB) often ceases spontaneously, re-bleeding occurs in about 30%. Bleeding diverticulum can be treated directly by endoscopic hemostasis; however, it is difficult to perform colonoscopy all cases with limited medical resource and certain risks. The aim of this study was clarify who should undergo as well appropriate methods initial management CDB patients. Methods: A total 285 patients were diagnosed underwent from March 2004 October...
Endoscopic submucosal dissection (ESD) for superficial duodenal epithelial tumors (SDETs) is technically difficult and has a high risk of adverse events. nasobiliary nasopancreatic duct drainage (ENBPD) may reduce the delayed events by preventing exposure post-ESD mucosal defect to bile pancreatic juice. This study was performed evaluate safety feasibility ENBPD after ESD.Patients who underwent ESD SDETs from July 2010 March 2020 were included. We collected data on success rate ENBPD, due...
Objectives Although endoscopic submucosal dissection (ESD) training is important, quantitative assessments have not been established. This study aimed to explore a novel assessment system by analyzing an electrical surgical unit (ESU). Methods was ex vivo study. Step one: identify the efficiency indicators, 20 endoscopists performed one ESD each, and we analyzed correlations between their resection speed status. two: precision three experts novices compared stability of three: in step two 19...
Objectives Fever and increased inflammatory responses sometimes occur following endoscopic resection (ER). However, the differences in causes according to organ are scarcely understood, several modified ER techniques have been proposed. Therefore, we conducted a comprehensive prospective study investigate cause of fever response across multiple organs after ER. Methods We included patients who underwent gastrointestinal submucosal dissection (ESD) duodenal mucosal at our hospital between...
Abstract Background and study aims Superficial pharyngeal cancers can be cured with transoral surgery (TOS), which preserves organ function quality of life. Pharyngeal endoscopic submucosal dissection (ESD) is challenging to perform because limited maneuverability complex anatomical features. The water pressure method (WPM) useful for natural traction techniques during ESD potentially ESD. This aimed investigate the short-term outcomes WPM-ESD lesions. Patients methods Therapeutic patients...
