Maydl hernia

Last revised by Dr Daniel J Bell on 27 Dec 2020

Maydl hernias (alternative plural: herniae) are defined as the presence of two small bowel loops within a single hernial sac, that is, there are two efferent and two afferent loops of bowel, forming a "W" shape. Hence sometimes known as a W hernia or a hernia-in-W.

This type of hernia is more prone to strangulation and necrosis. The intervening intra-abdominal loop is also at risk of a closed loop obstruction.
