The Japan Gastroenterological Endoscopy Society has developed endoscopic submucosal dissection/endoscopic mucosal resection guidelines. These guidelines present recommendations in response to 18 clinical questions concerning the preoperative diagnosis, indications, methods, curability assessment, and surveillance of patients undergoing for esophageal cancers based on a systematic review scientific literature.
Background & AimsEsophagectomy is the standard treatment for stage I esophageal squamous cell carcinoma (ESCC). We conducted a single-arm prospective study to confirm efficacy and safety of selective chemoradiotherapy (CRT) based on findings from endoscopic resection (ER).MethodsWe performed patients with T1b (SM1–2) N0M0 thoracic ESCC December 2006 through July 2012; 176 underwent ER. Based ER, received following: no additional pT1a tumors negative margin lymphovascular invasion (group A);...
<b><i>Background:</i></b> Endoscopic submucosal resection (ESD) and endoscopic mucosal (EMR) are well established as curable safety procedures for treating superficial tumors of the stomach, esophagus colon. However, a majority strategies non-ampullary duodenal (NASDTs) remains undefined. The aim this study was to clarify which right method NASDT treatment - EMR or ESD. <b><i>Summary:</i></b> We analyzed 129 consecutive (74 ESD 55 EMR)...
<b>Background and study aim:</b> Esophageal stricture following endoscopic submucosal dissection (ESD) can be a serious complication in patients with large mucosal defects. This preliminary examined the efficacy of using polyglycolic acid (PGA) sheet fibrin glue for prevention esophageal after ESD. <b>Patients methods:</b> A total 15 were enrolled. After resection, PGA sheets placed over surgical wound. The size defect was estimated by dividing circumference esophagus into 12 parts equal...
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...
<b>Background and study aims:</b> The clinical benefit of endoscopic submucosal dissection (ESD) for superficial duodenal neoplasias has not yet been verified. aims this were to validate the feasibility long-term outcomes ESD nonampullary neoplasias, larger than 20 mm. <b>Patients methods:</b> 41 patients, with large who underwent between April 2005 March 2013 included in study. short- retrospectively evaluated, related tumor size, resection histological type, invasion depth, complete rate,...
Background and Aim A novel diagnostic algorithm for magnifying endoscopy with narrow band imaging ( ME‐NBI ) superficial non‐ampullary duodenal epithelial tumors SNADET is needed because of difficulties. Methods In the present study, images taken prior to endoscopic treatment were retrospectively analyzed investigate relationship between findings pathological findings. Lesions displaying a single surface pattern classified as monotype, those multiple patterns mixed type. Surface was...
To clarify optimal therapeutic strategies for early gastric cancers without vestigial remnant or recurrence, we evaluated the benefits of endoscopic mucosal resection (EMR) and submucosal dissection (ESD) according to tumor size location.From January 2000 December 2007, a total 328 lesions were treated using conventional EMR, while 572 by ESD. Patients who underwent surgery on upper gastrointestinal tract before EMR ESD excluded from study. We compared size, location rates complete...
Background: Esophagogastric junction (EGJ) cancers are not only located in regions anatomically difficult for endoscopic submucosal dissection (ESD), but they also have higher clinicopathological malignant potential than non-junctional gastric (NJC). Despite this, no ESD-based comparative studies of junctional cancer (JC) and NJC been conducted to date. The aims this study were clarify the characteristics EGJ short- long-term outcomes after ESD. Methods: Between April 2005 December 2010, ESD...
Duodenal endoscopic submucosal dissection (ESD) is technically challenging because of anatomical specificities and, to date, has not been validated concerning the high rate complications such as perforation and delayed bleeding. In present study, risk factors for bleeding after duodenal ESD are presented with goal establishing preventive measures.We analyzed 63 patients non-ampullary superficial neoplasias treated by from April 2005 March 2014. To analyze ESD, we divided into a group...
<b><i>Background:</i></b> Endoscopic submucosal dissection (ESD) was developed to resect early gastric cancer (EGC), which could not be resected by conventional endoscopic mucosal resection, and the indications for ESD are expanding include more types of EGCs. Favorable long-term outcomes EGCs that meet expanded curability criteria have been reported. However, non-curative known in detail. <b><i>Summary:</i></b> We analyzed 165 patients after...
Esophageal stricture occurs at a high rate after endoscopic submucosal dissection, especially entire circumferential leading to poor quality of life. This retrospective cohort study evaluated the in mucosal defect cases following modified steroid administration. We enrolled 22 consecutive patients who underwent dissection for superficial esophageal cancer between April 2010 and 2015 our hospital. Until January 2013, systemic steroid-prednisolone-was administered 30 mg/day tapered over 8...
Aim: Helicobacter pylori-naïve gastric cancers(GCs) have not been well documented. We aimed to characterize early H. GCs. Subjects and Methods: Of 666 patients with GC resected by endoscopic submucosal dissection, were extracted according the definition: no pylori eradication history, negative for serum pylori-antibody current pylori-infection tests, atrophy pepsinogen (PG) test, endoscopy, histology. Results: It was found that 16 GCs pylori-naïve, classified into undifferentiated...

Gastric submucosal tumor (SMT) is frequently found during screening endoscopy, but definitive diagnosis based on histological confirmation relatively difficult. Even without accurate before treatment, open or laparoscopic surgery currently carried out to remove SMT. The purpose of this study was demonstrate the feasibility endoscopic dissection (ESD) in diagnostic treatment for stomach. Subjects case comprised nine patients who had undergone ESD gastric Before ultrasonography all cases...
