Salvage endoscopic submucosal dissection for incompletely resected esophageal or gastric neoplasms (case series)

Background and study aims Given that positive lateral margins indicate possible residual carcinoma, salvage endoscopic submucosal dissection (ESD) should be considered for curative therapy. Presence of submucosal fibrosis, however, makes the procedure difficult to perform. We present our case series to discuss the feasibility of salvage ESD and the timing of the procedure.
