Endoscopic dissection of large endogenous myogenic tumors in the esophagus and stomach is safe and feasible: A report of 42 cases

Abstract

ED is safe and feasible for resection of endogenous EL and GST in selected cases.

Endoscopic submucosal dissection for treatment of esophageal submucosal tumors originating from the muscularis propria layer

“…With ESD technology improved, it was used not only for mucous layer tumors but for muscularis propria tumors of the digestive tract and has produced good therapeutic effects. [11][12][13][14] In this process, ESD is used to cut off the mucosa and submucosa layer from the tumor and to peel the tumor from the muscularis propria, which can reduce the risk of perforation. We consider this application a new technology related to ESD-endoscopic submucosal excavation.…”

Endoscopic submucosal dissection of large gastrointestinal stromal tumors in the esophagus and stomach

“…Its feasibility and efficacy have been confirmed in large series of cases with gastric neoplasms . However, reports of the application of ESD to large‐size GISTs are scant and limited to case reports . In recent 2 years, a new endoscopic intervention has also been developed from the ESD technique, namely, submucosal tunnel technique which was first described by Japanese experts .…”

“…13,14 Especially, the emergence of endoscopic submucosal dissection (ESD) has made the en bloc resection of lesions arising from submucosal and muscularis propria possible. [15][16][17][18][19] However, only a few data are available for the application of this technique to large-size tumors, [18][19][20] and further evaluation of this new attempt need to be carried out. With the enrichment of experience in ER and low incidence of complications, we have applied the ESD technique to large-size GI lesions.…”

Clinical outcomes of per‐oral endoscopic tumor resection for submucosal tumors in the esophagus and gastric cardia

“…Thus, a safe, efficacious, and cost‐effective method for therapeutic resection and histologic diagnosis of esophagogastric SMTs is desirable. Resection of SMTs using endoscopic mucosal resection (EMR) and endoscopic submucosal resection (ESD) have been previously described . However, these techniques are generally limited to SMTs arising from muscularis mucosa, whereas SMTs arising from muscularis propria have traditionally been resected surgically …”
