Abstract Text A 61-year-old patient with esophageal (cT2N0M0) and pharyngeal (cT3N2M0) squamous cell cancers was referred for a 25-mm rectal lesion. Endoscopy showed a demarcated lesion (Paris 0-Is+IIc, JNET-3), EUS suggested muscularis propria involvement. Endoscopic submucosal dissection with a pocket technique was performed to access the suspected deeply invasive component (SIC), marked by loss of the dissection plane due to adhesion to the muscularis propria. After isolation of the SIC a knife-assisted circumferential incision of the muscularis propria was performed 3mm around the SIC. The resection defect was closed with clips, and antibiotics were given post-procedure. Histopathology confirmed R0 resection of a low-grade adenocarcinoma (pT1b, sm3) with focal lymphovascular invasion. The MDT recommended endoscopic and radiologic follow-up, which showed no recurrence or metastases at six months.
