An incision is made along the lower margin of the area to be denuded, as shownin Fig. 515, and the mucous membrane is raised as a flap, as shown in Fig. 518. The area of denudation is nearly the same as in Hegars operation but it has overit a large flap.

Furthermore, the flap-method gives alarge raw surface for approximation without any loss of tissue, and the amount oftissue left in the flap adds somewhat to the mass which fills the weak place in thepelvic floor. A distinct disadvantage of the flap is that it may prevent free access to the upper. .^1 Fig. 516. Tails Operation. The Line of Incision forLaceration into tlie Rectum.

This operation is especially applicable in those cases where it is important toavoid loss of tissue, particularly in cases of laceration into the rectum that haveresisted one or two previous operations. In some such cases, there is so much scar-tissue and apparently so much loss of tissue that approximation over a wide areaby ordinary denudation can not be secured without injurious tension. In such a STEPS IN TAITS OPERATION 501 case the main object is to secure union of the sphincter muscle and the rectal wall,and this is more certain
