Endoscopic submucosal dissection with sheath-assisted counter traction using a novel sheath for early gastric cancers.

Abstract

BACKGROUND/AIMS:

Endoscopic submucosal dissection (ESD) is technically demanding and requires considerable skill. We previously described sheath-assisted counter traction ESD that uses simple materials and methods to improve cutting line visualization. We recently improved counter-traction of the submucosal layer using a novel chemically treated sheath that reduces slippage and maintains traction, and investigated the utility of the novel sheath for ESD.

METHODOLOGY:

Forty-three and 25 consecutive patients with early gastric carcinomas were treated by standard ESD and traction ESD assisted with novel sheaths, respectively. The mean duration of procedures relative to tumor size and location, as well as complications after ESD between the two groups were compared.

RESULTS:

The mean duration of ESD procedures for lesions =20mm in diameter was significantly reduced using the novel sheath. The mean duration of procedures for all locations of resected tumors in the stomach was significantly reduced using the novel sheath. However, no perforation and delayed bleeding developed after treatment with the novel sheath.

CONCLUSIONS:

Sheath-assisted counter traction ESD by the novel sheath was technically simpler and thus less time-consuming regardless of the location of lesions, especially when =20mm in diameter. The traction ESD with the novel sheath is safe and not invasive, and it can be universally applied to standard ESD.
