Fig. 1An illustration showing clip with line method. A clip with line was placed at the edge of the target lesion when the circumferential incision was completed. Good counter traction and a clear field of vision were obtained when the line was pulled very gently (reprinted from Oyama T, et al. Stomach Intest 2002;37:1155-1161, with permission).2
Fig. 2The second clip can change the direction of traction (reprinted from Oyama T, et al. Stomach Intest 2002;37:1155-1161, with permission).2
Fig. 3A long, 3-0, silk line was tied to the arm part of the clip.
Fig. 4The clip with line is reset in the cassette. Then the clip with line can be set in the applicator like a usual clip.
Fig. 5Endoscopy showed a well demarcated semicircumferential iodine unstaind lesion in the lower esophagus.
Fig. 6The circumferential incision was completed. The next step is submucosal dissection. However, the field of vision was not clear enough because the submucosal space is narrow.
Fig. 7The clip with line was placed at the submucosal side of the targeted specimen.
Fig. 8A clear field of vision and adequate counter traction were gained when the line was pulled gently.
Fig. 9Procedure after traction. (A, B) The movement of specimen could be stopped by the traction made by the line. Submucosal dissection was then performed more easily, safely, and quickly.
