Endoscopic mucosal autograft for treating esophageal caustic strictures: preliminary human experience

by He et al.

Fig. 1 Images from the endoscopic mucosal transplant procedures performed in patient #1. a A severe luminal stricture with white cicatricial tissue and local erosion located at 32cm from the incisor. b Normal upper esophageal mucosa was selected and endoscopically dissected. c The successfully excised donor tissue was approximately 5.0 × 1.0cm. d The separated hard-palate mucosa was approximately 2.0 × 2.0 cm in size and was transferred in saline. e The isolated mucosal patch was delivered endoscopically. f The isolated mucosal patch was attached to the defect region, after the section had first been dilated, using several clips and fibrin tissue glue.
