Abstract

BACKGROUND:

The usefulness of clip traction in endoscopic submucosal dissection (ESD) for early esophageal carcinoma was investigated.

METHODS:

A total of 87 patients who underwent ESD for esophageal squamous cell carcinoma were included in the study. The hook knife method was used for ESD. Twenty patients underwent ESD without clip traction (non-clip group) and 67 underwent procedures in which clip traction was used (clip group). A clip with a string was attached to the oral edge of the lesion after mucosal incision in the clip group.

RESULTS:

ESD was successful in all cases. Wide exposure of the submucosal tissue below the lesion was obtained by applying tension to the clip traction. The duration of ESD was shorter in the clip group, and there was a significant difference in duration between the non-clip and clip groups. There were no complications of ESD in the clip group, but muscle layer injury occurred in three patients in the non-clip group.

CONCLUSION:

Clip traction shortens operating time and is safer in esophageal ESD. Clip traction is recommended as a useful auxiliary procedure.
