CHAPTER 17. RIGID SIGMOIDOSCOPY
The Corpus Hippocraticum of early medical works from ancient Greece described both proctoscopy and use of the rectal speculum, constituting the earliest published reference to endoscopy.
INTRODUCTION
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.
INDICATIONS
• Symptoms or signs suggestive of anorectal or colonic pathology.
• As a routine investigation prior to anorectal procedures.
• Biopsy of anal canal.
• Removal of foreign bodies in the anal canal.
CONTRAINDICATIONS
Some of these are relative contraindications. The main concern is that of potential perforation.
EQUIPMENT
• Gloves.
