Sigmoid mesocolon hernia

Dr Henry Knipe and Dr Bruno Di Muzio et al.

Intersigmoid hernias, also known as sigmoid mesocolon hernias, occur when small bowel loops protrude into a peritoneal pocket (intersigmoid fossa) formed between two adjacent sigmoid segments and their mesentery.


Sigmoid mesocolon hernias account for ~5% of all internal hernias 1-2.


Sigmoid mesocolon hernias are divided by some authors into three categories 1,3:

  • intersigmoid hernia
  • transmesosigmoid hernia
  • intermesosigmoid hernia

It is difficult, maybe impossible, to distinguish these subtypes preoperatively with no clear radiographic sign identified to distinguish among the three subtypes 1-2. Thus, most radiologists and surgeons just refer to intersigmoid hernias, rather than trying to distinguish between them.
