WE REPORT A successful case of endoscopic fullthickness resection (EFTR) with endoscopic hand suturing (EHS) for rectal cancer. A 74-year-old male was referred to our department for the endoscopic resection of a 20-mm flat, elevated lesion, the oral part of which was unexpectedly interrupted at an anastomotic site that was created by a double stapling technique followed by a seromuscular suture due to low anterior resection surgery for advanced rectal cancer. As the flat lesion was already detected during preoperative colonoscopy, the oral part of the lesion was likely entangled by the circular stapler, and the tumor cells might be buried in the everted anastomotic line. Following the patient’s desire, we conducted EFTR with EHS to obtain complete resection (Fig. 1). Under
