Perineal hernia have a prevalence of 0,1-0,4% in older dogs, 84% of them are intact males. Herniation is initiated by a weakness of the pelvic diaphragm and often accompanied by prostatic diseases/hyperplasia.
Typical contents of the hernia are retroperitoneal fat, fluid, rectum (sacculation or flexure), prostate, paraprostatic cysts, bladder, jejunum, colon or connective tissue.
The described laparatomy technique allows – in contrast to the other surgical methods e.g. standard herniorrhaphy – recognition, assessment, reduction and fixation of displaced organs which may contribute to the development of the hernia. So the tubular structure of the rectal lumen can be regained and the prostate and bladder can be fixed cranioventrally to the pelvic inlet.
As usual in perineal hernia in intact males, castration was also mandatory with this technique.
The degree of severity and the number of complications were lower with this surgical technique than with other reported studies.
