Abstract Text A 57-year-old female presented with a 25-mm sessile distal rectal pseudodepressed
lesion (Paris 0-IIa+0-IIc, surface pattern JNET2B, NICE2 -periphery- and NICE 3-center).
EUS raised suspicion of muscularis propria involvement. A multidisciplinary team recommended
endoscopic resection, which was performed after patient agreement. Submucosal injection,
pre-cut, and tunneling were followed by intermuscular dissection of the center of
the lesion due to suspected muscularis propria invasion.The defect was closed completely.
The patient had no complications and was discharged 24h post-procedure. Histopathology
confirmed R0 resection of an adenocarcinoma pT2, with no lymphovascular or perineural
invasion. This case highlights R0 endoscopic intermuscular dissection as a viable
option for cases of initial T2 of the distal rectum [1]
