Colon Layout Guide for KKM40

Skills Gained

Primary Level Case

Primary Level

Case 1: Introductory Level 1 - simple layout appropriate for first-time trainees
Case 2: Introdcutory Level 2 - as 1 with longer sigmoid colon. An essential training step before moving on to actual patients
Case 3: Straighten out the "Alpha" loop - still a simple layout, with a naturally formed "Alpha" loop in a longer sigmoid colon. With insertion, the colonscope        naturally forms an "Alpha" loop, and advances towards the splenic flexure

Secondary Level

Case 4: Redundant sigmoid colon, "N" loop formation and long transverse colon. - a challenging layout, with difficult-to-shorten sigmoid colon and drooping transverse colon
Case 5: Redundant sigmoid colon and "Alpha" loop formation - an "Alpha" loop is formed by the redundant sigmoid colon, therefore, passing through the sigmoid colon by shortening method is extremely challenging.

Advanced Level

Case 6: "Reverse Alpha" loop formation - due to the significantly redundant sigmoid colon, a "reverse alpha" loop is formed by insertion of the colonoscope.
