Effect of electroacupuncture on discomfort in patients undergoing colonoscopy: protocol for a multicentre, randomised, controlled clinical trial.

Introduction: Colonoscopy is currently the most commonly used and effective method for early detection, diagnosis and treatment of tumours of the colon and rectum. However, similar to other invasive procedures, it is associated with adverse reactions such as pain and abdominal distension. Electroacupuncture (EA) has been proposed as a potential treatment for relieving this discomfort; however, there is limited evidence supporting its efficacy.
