Applicability of Endoscopy and Endoscopic Treatment
If there is an official standard on the applicability of endoscopy and endoscopic
treatment that is defined by the hospital’s administration or other official
institutions such as academic societies on endoscopy, follow that standard.
Before starting endoscopy and endoscopic treatment, thoroughly evaluate its
properties, purposes, effects, and possible risk (their natures, extent and
probability). Perform endoscopy and endoscopic treatment only when its
potential benefits are greater than its risks.
Fully explain to the patient the potential benefits and risks of the endoscopy and
endoscopic treatment as well as any examination/treatment methods that can be
performed in its place, and perform the endoscopy and endoscopic treatment
only after obtaining the consent of the patient.
Even after starting the endoscopy and endoscopic treatment, continue to
evaluate the potential benefits and risks, and immediately stop the
endoscopy/treatment and take proper measures if the risks to the patient
become greater than the potential benefits.
