Submucosal Tunnel Endoscopic Resection for Esophageal Submucosal Tumors: A Multicenter Study

Endoscopic submucosal dissection for small submucosal tumors of the rectum compared with endoscopic submucosal resection with a ligation device

AIM To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for small rectal submucosal tumors (SMTs). METHODS Between August 2008 and March 2016, 39 patients were treated with endoscopic submucosal resection with a ligation device (ESMR-L) (n = 21) or ESD (n = 18) for small rectal SMTs in this study. Twenty-five lesions were confirmed by histological evaluation of endos...

Endoscopic submucosal tunnel dissection of a bronchogenic esophageal cyst.

A 23-year-old man was admitted to our hospital with the complaint of chest discomfort and dyspnea for the previous 3 months. Upper endoscopy showed a 2.5×2.0cm bulging lesion in the distal esophagus (●" Fig.1). Endoscopic ultrasound revealed a 1.1×2.5cm hypoechoic cystic lesion arising from the muscularis propria (●" Fig.2). Endoscopic submucosal tunnel dissection (ESTD) was performed using a h...

Endoscopic Resection for Small Rectal Neuroendocrine Tumors: Comparison of Endoscopic Submucosal Resection with Band Ligation and Endoscopic Submucosal Dissection

Background and Aims. There is no consensus so far regarding the optimal endoscopic method for treatment of small rectal neuroendocrine tumor (NET). The aim of this study was to compare treatment efficacy, safety, and procedure time between endoscopic submucosal resection with band ligation (ESMR-L) and endoscopic submucosal dissection (ESD). Methods. We conducted a prospective study of patients...

Submucosal Endoscopic Tumor Resection

Submucosal tunneling endoscopic resection for multiple esophageal leiomyomas.

A 61-year-old man presented for treatment of esophageal submucosal tumors (SMTs). The SMTs had been found 1month previously at his local hospital during a health examination. Upon presentation, his physical examination and laboratory tests were unremarkable. Esophagogastroduodenoscopy (EGD) revealed two protruded lesions in the middle of the esophagus (●" Fig.1; ●" Video1). Endoscopic ultrasono...
