Herein, we present the case of an 85-year-old man referred to advanced endoscopy for a 60-mm recurrent polyp adjacent to the ileocecal valve.

A total of 3 colonoscopies with EFTR using the FTRD were performed with successful removal of the recurrent polyp.

Polyps were manually annotated (Label Studio; HumanSignal, San Francisco, Calif, USA), and the nnU-Net framework (Applied Computer Vision Lab of Helmholtz Imaging and the Division of Medical Image Computing at the German Cancer Research Center, Heidelberg, Germany) was used to automate polyp segmentation.

A 25-year-old man with trisomy 21 and eosinophilic esophagitis presented with acute food bolus impaction. After unsuccessful conventional endoscopic maneuvers, a cryoprobe was externally attached to an endoscope and used to achieve cryoadhesion and extraction of the meat bolus. Within 10 minutes, the meat bolus was successfully removed attached to the cryoprobe without mucosal injury.
