Detachable string magnetically controlled capsule endoscopy for complete observation of the upper gastrointestinal tract.

Background: Wireless magnetically controlled capsule endoscopy (WMCCE) was feasible, well tolerated, highly acceptable, and had high consistency in diagnosis of gastric diseases with esophagogastroduodenoscopy (EGD). But WMCCE is not suitable for inspection of the esophagus. We developed detachable string magnetically controlled capsule endoscopy (DS-MCCE) to observe gastroesophageal diseases.

Comparing about three types of endoscopic therapy methods for upper gastrointestinal submucosal tumors originating from the muscularis propria layer.

Endoscopic submucosal excavation (ESE), endoscopic full-thickness resection (EFTR) and submucosal tunneling endoscopic resection (STER) have been widely applied to upper gastrointestinal submucosal tumors (SMTs) originating from the muscularis propria (MP) layer in recent years. But until now, there are few studies that comparing the efficacy and safety of three endoscopic therapy methods. From January 2013 to August 2018, a total of 218 patients with SMTs who underwent ESE, EFTR or STER were enrolled in this retrospective study.
