The size of the human omentum and methods of lengthening it for transplantation.

The size of the omentum is variable and can only be predicted within the standard deviations. However, the lower limits of its size have now been ascertained over a large series and it is clear that it could be lengthened sufficiently to reach the vault of skull, mid-leg or mid-forearm levels in all cases. Of course, to do so will decrease its width. An alternative to pedicle transfer is to use the whole omentum as a free transplant by vascular anastomosis.
