Endoscopic submucosal dissection of challenging rectosigmoid anastomotic lesion made feasible by a multipolar adaptive traction device combined with a line

Endoscopic submucosal dissection (ESD) is widely accepted as a minimally invasive treatment for most superficial colorectal neoplasms, enabling a high rate of en bloc R0 resection [1]. However, ESD is difficult to perform in selected cases, such as in anastomotic lesions following colorectal surgery. In such instances, ESD presents technical challenges due to severe fibrosis, limited space, the presence of staples, deformities, and suture lines from previous surgeries, which increase the risk of complications and unsuccessful outcomes [2] [3].

We have already discussed the benefits of using an adaptative traction device (A-TRACT) in selected difficult lesions [4] [5].

In this case we report the use of an A-TRACT 2+2 associated with a line ([Fig. 1]) to maximize the effects of traction during dissection of a rectosigmoid anastomotic lesion ([Video 1]).

A 76-year-old man was referred for ESD of a 10-mm lesion located at the rectosigmoid anastomosis. After circumferential incision and trimming, the A-TRACT 2+2 was applied by placing the four loops on the lesion’s edges. The line that had previously been attached to the A-TRACT was gently pulled to improve the traction ([Fig. 2]). Underwater ESD was used during the dissection phase to optimize the visibility of the submucosa and muscularis propria. Any staple encountered during the procedure was either removed or avoided, ensuring the excision line was made below it within the thickened muscularis propria. After cutting half of the lesion, the A-TRACT was tightened, and the line was pulled slightly more to better expose the layers. The procedure was concluded without adverse events. The histopathology revealed an adenoma with high grade dysplasia and free margins.

We can infer that the use of a line attached to the A-TRACT system offers improved adaptability of traction, potentially making ESD of rectosigmoid anastomotic lesions with limited lumen space safer and more feasible.
