Aim: The aim of this study was to examine the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cancer based on approximately 10 years’ experience. Methods: Endoscopic submucosal dissection was performed in 1272 patients with early gastric cancer (1657 lesions). We examined en bloc resection rate, curative resection rate, local recurrence rate, procedure time, and ...

The endoscopic examination of a 64-year-old male patient revealed a gastric submucosal tumor in the anterior wall of the gastric antrum. The lesion increased in diameter to 25 mm and was resected completely with endoscopic submucosal dissection (ESD). Histological examination of the submucosal tumor gave a diagnosis of an inflammatory fibroid polyp (IFP). It is suggested that ESD may be an effe...

Carpeted villous adenomas of rectum may be extensive and not suitable for transanal excision or Endoscopic mucosal resection. We present a case of such lesion extending from anorectal junction to rectosigmoid region. After biopsy and staging, this was managed by a sphincter saving procedure, i.e. a combination of transabdominal total mesorectal excision and transanal intersphincteric dissection...

Submucosal tunneling endoscopic resection (STER) combines the techniques of peroral endoscopic myotomy [1] and endoscopic submucosal dissection for removal of upper gastrointestinal tract submucosal tumors (SMTs). STER has beenused for removal of small SMTsbelow 20mmwith low complication rates [2–4]. This report describes the removal of a large 40-mm esophageal SMT using STER, and describes a n...

BACKGROUND/AIMS This study evaluated the role of a second-look endoscopy after gastric endoscopic submucosal dissection in patients without signs of bleeding. METHODS Between March 2011 and March 2012, 407 patients with gastric neoplasms who underwent endoscopic submucosal dissection for 445 lesions were retrospectively reviewed. After the patients had undergone endoscopic submucosal dissecti...

Surgery has been considered the main treatment for submucosal tumors (SMTs). However, endoscopic resection is currently accepted gastric SMTs smaller than 3 cm. Endoscopic dissection (ESD) technique of choice, and tunneling successful results with low complication rates according to recent meta-analysis by Cao et al. The major limitation these methods technical difficulty associated certain ana...

Submucosal pedunculated masses of the hypopharynx, larynx, and upper esophagus pose diagnostic and treatment challenges for gastrointestinal endoscopists. Because of potentially acute respiratory complications, the removal of these pedunculated masses through a transoral, transcervical, transthoracic, or endoscopic approach, depending on their location and size, is mandatory [1]. Inflammatory p...

Endoscopic submucosal dissection has made it possible to resect large lesions during a single operation. The present study was undertaken to compare the time taken for recovery from artificial ulcers after endoscopic submucosal dissection between an H(2) Receptor Antagonist treatment group and a Proton Pump Inhibitor treatment group, focusing on analysis of the time course of reduction rate in ...

Advances in endoscopic submucosal dissection include a submucosal tunneling technique, involving the introduction of tunnels into the submucosa. These tunnels permit safer offset entry into the peritoneal cavity for natural orifice transluminal endoscopic surgery. Technical advantages include the visual identification of the layers of the gut, blood vessels, and subepithelial tumors. The creati...

Introduction: Endoscopic submucosal dissection has been widely accepted as a standard treatment for early gastric cancers. However, endoscopic submucosal dissection for an early gastric remnant cancer post-proximal gastrectomy with jejunal interposition is not yet widespread. Case Series: A large, flat, elevated lesion was detected in an 83-year-old male (Case 1), whereas two separate flat, ele...
