Schema of endoscopic submucosal tunnel dissection with ringthread countertraction. A, A large lesion covered the lesser curvature of the stomach. B, Although the submucosal tunnel was created from the oral side to the anal side, we could not approach the posterior side because of the extensive fibrosis. C, The ring-thread counter traction provided a good view to approach the fibrosis area.

... effectiveness of endoscopic submucosal tunnel dissection (ESTD) has been reported as a good method for providing traction. 1,2 However, ESTD alone did not provide enough traction in this case because of the lesion size and extensive severe fibrosis. In such a situation, combined use of traction by using ring-thread counter traction was effective (Fig. ...

Background/aims:
Endoscopic submucosal dissection (ESD) for residual or recurrent colorectal lesions after incomplete resection is challenging because of severe fibrosis. This study aimed to compare the efficacy of the pocket-creation method (PCM) with a traction device (TD) with that of conventional ESD for residual or recurrent colorectal lesion...
