Surgical Procedure

Outline of hernial area under the skin.
Preparing the area for surgery.
Making the incision over the hernia.
The area of the hernia is outlined.
The surgical site is "prepped" for surgery. The incision is made just to the right of the base of the tail and over the hernial sac.
The hernial sac is exposed
...and inspected.
Gently the surgeon dissects to the membrane (called the peritoneum) that contains the abdominal contents which   have found their way under the skin.
The hernial sac is beginning to be visible. Here the sac is isolated and assessed for any dead or infected tissue that may result from a lack of proper blood circulation to this area.
Replacing the hernial contents back where they belong.
Deep sutures to stabilize the area.
More sutures to close the space.
The contents of the sac and the sac itself are pushed back between the muscles of the pelvic area and into the pelvic abdominal cavity where they belong. 
The surgeon is using a needle holder forceps and beginning to suture the hernial space closed. The goal is to eliminate any space where the hernia could return. A number of non-absorbable sutures are required to   tightly close a space this large.
The skin is sutured closed and the dog is kept confined to a leash for three to four weeks after the surgery.  The long term prognosis for a complete recovery is generally very good.   On occasion the sutures could break down or other factors may contribute to a   reoccurrence of the hernia.  An artificial mesh screen can then be used to seal the opening.
