Focal endoscopic intermuscular dissection guided by the pocket-detection method for radical excision of early T2 rectal cancer

Abstract Text An 80-year-old male patient was referred due to a 20mm, Paris 0-IIa+c distal rectal lesion suggestive for a deeply invasive cancer. Radiological staging excluded distant metastases or nodal involvement. Creating a submucosal pocket towards the deeply invasive component (pocket-detection method), the muscle retracting sign was identified. Applying multipoint traction, the deeply invasive component was isolated performing endoscopic submucosal dissection. Then, incision of the circular muscular layer was performed circumferentially around the invasive component at a distance of 3mm to ensure radicality and focal endoscopic intermuscular dissection (EID) was completed without intra or postprocedural complications. The patient was discharged 24 hours after the EID. Histopathology revealed an R0 resection of a low-grade pT2 adenocarcinoma without tumor budding or lympho-vascular invasion.
