A 63-year-old male was found to have a sessile serrated adenoma extending inside the
appendix.
After discussing the different options, he decided to proceed with endoscopic full-thickness
resection.
The polyp was pulled inside the FTR cap, following that the FTR clip was deployed
and the polyp was resected and retrieved. He had rectal bleeding the day after the
procedure. Repeated colonoscopy showed a stable blood clot at the site of FTR without
active bleeding. He did not require a blood transfusion and was discharged after 48
hours of observation.
The final pathology was sessile serrated adenoma with clear margins.
