rectal instruments


By • Дек 26th, 2010 • Category: Rectum

The operation to narrow and strengthen the sphinc­ter by means of a silver wire is used in elderly or obese patients.

Two small incisions are made anteroposteriorly to the anus (Pig. 112), and a silver wire 2 mm in diameter is drawn around the anal sphincter, (Fig. 114.1, 114.2 and 114.3) being tightened on the surgeon’s index finger or the bouge fully introduced into the rectum (Fig. 115).

After twisting and cutting off the wire ends .the wounds are sutured with catgut.

It is essential that the wire be placed externally to the sphincter and be not palpable from the side of the anal mucosa (Fig. 116)
