In our institution, pocket-creation-method(PCM) for endoscopic-submucosal-dissection(ESD), is combined with saline-immersion-therapeutic-endoscopy(SITE); this further facilitates PCM-ESD by improving view quality (through refractive magnification and minimal lense fogging) and lesion lifting (through buoyancy).

A 82-year-old man presented a circumferential rectosigmoid 11 × 8 cm granular-laterally-spreading-tumour (mixed-nodular-type)(LST-G).

Two submucosal pockets were created on both lateral sides of the lesion. After adequate, deep submucosal dissection was achieved, the two pockets were connected. The circumferential, en-bloc-resected specimen was retrieved for histopathological evaluation, which reported tubular adenoma with low and foci of high-grade dysplasia, demonstrating complete excision.

SITE-PCM-ESD for giant circumferential colorectal lesions is a feasible minimally-invasive alternative to surgery.
