Passing a colonoscope through a 6-foot-long colon is a challenging task, not least because there is an infinite variability in the anatomy of the large bowel. Anatomic heterogeneity is matched by the wide variation in skill level within the family of colonoscopists, and the combination of colon and colonoscopist is manifest and summated in the degree of difficulty of any examination. Attempts at measuring difficulty are obviously subjective and depend not only on colonic tortuosity and colonoscopist skill but also on the degree of anesthesia provided to the patient. This chapter defines difficulty in colonoscopy and makes suggestions on how to overcome it.

摘要

Passing a colonoscope through a 6-foot-long colon is a challenging task, not least because there is an infinite variability in the anatomy of the large bowel. Anatomic heterogeneity is matched by the wide variation in skill level within the family of colonoscopists, and the combination of colon and colonoscopist is manifest and summated in the degree of difficulty of any examination. Attempts at measuring difficulty are obviously subjective and depend not only on colonic tortuosity and colonoscopist skill but also on the degree of anesthesia provided to the patient. This chapter defines difficulty in colonoscopy and makes suggestions on how to overcome it.
