Overlong or twisted afferent loop cause endoscopic insertion failure. A In a case with overlong afferent loop, the length of the enteroscope was insufficient to reach bilioenteric anastomosis site. B Afferent loop between poke hole of the transverse mesocolon and bilioenteric anastomosis was severely twisted, causing failed endoscopic insertion.
