Rigid sigmoidoscopy is a procedure that is usually performed in an out-patient setting. The transparent anoscope allows a 360 view of the anal canal and rectum, and hence has a significant role in the evaluation of anorectal and distal colonic pathology. This invasive procedure should be performed with care and sensitivity, maintaining the patient’s dignity at all times. This can only be learned after observing a senior colleague perform the procedure, and subsequently talking through the technique before performing it yourself under supervision.
