Having once insinuated itself through the transversalis fascia,the abdominal contents, usually omentum, pushes the vascularprolongation of this fascia ahead of it and now becomes a truehernia. From this point on its development depends almostentirely upon two factors, viz., the amount of intra-abdominalpressure, the vis-a-tergo, and the resistance to be overcome—that is, the holding ability of the structures composing the sac. Usually the sole contents of the sac at this stage is intestines follow on after the omentum pushing it onbefore them in the growing hernial sac. If the omentum bewell developed and abundantly supplied with adipose tissue, itmay serve to plug the hernial ring to such an extent as to actuallyexclude the small intestine until the hernial sac shall haveattained a size sufficient to contain practically the entire Fig. 4.—Large umbilical hernia showing portion of normal unbilicus stillintact.
