FIG. 1.

Left panel shows the inversion technique. Drawing back on the plastic cable at the site of the gastrostomy facilitates inversion of a sleeve of attached mucosal and submucosal layers. Using this technique, the remaining attachments are stripped away from the muscularis externa, thereby freeing the entire sleeve of tissue. The sleeve is then retrieved and exited through the mouth. The right panel demonstrates a 13-cm-long sleeve of esophageal inner layers removed from patient no. 3. The tube shaped sleeve was split longitudinally for subsequent fixation and histopathologic processing. Color images available online at www.liebertonline.com/tea
