Endoscopic intermuscular dissection for deep submucosal invasive cancer in the rectum: a new endoscopic approach
Fig. 1 Schematic representation of the endoscopic intermuscular dissection (EID) procedure illustrating: a a rectal lesion suspected of having deep submucosal invasion in the mid-rectum; b a partial circumferential cut of the mucosa, which is performed to gain access to the submucosal space; c,d the circular muscularis propria being cut at the luminal edge of the lesion to gain access to the intermuscular space; e the intermuscular space being dissected to remove the specimen en bloc, including the circular part of the
muscularis propria; f the specimen being removed using a retrieval net, leaving the longitudinal part of the muscularis propria exposed.
