This article reviews the evolution of ambulatory endoscopic treatment over time, taking into account tumor size, macroscopic type, and histology. The opportunities for outpatient endoscopic treatment have been greatly enhanced with the advent of underwater endoscopic mucosal resection (UEMR) in addition to cold snare polypectomy (CSP); the procedure can be actively performed in non-hospital, non-facility clinics, and patients can benefit greatly from appropriate diagnosis and selection of lesions. On the other hand, CSP has the disadvantage of not being able to resect deep enough beyond the muscularis mucosae, and physicians who perform CSP must be familiar with magnified endoscopic diagnostics such as JNET and Pit pattern diagnosis. Although tumor/non-tumor diagnosis by artificial intelligence is becoming possible, the final diagnosis is still the responsibility of the physician. In order to master outpatient endoscopic treatment of colorectal tumors, the endoscopist is responsible not only for endoscopic insertion but also for tumor detection, diagnosis, and treatment selection.
