HERNIA AND ITS CLASSIFICATION: 

HERNIA AND ITS CLASSIFICATION

Hernia: 

Hernia Abnormal protrusion of contents of a body cavity through normal or abnormal opening Constituents of hernia – Hernial ring Hernial sac – Hernial contents – intestine, omentum , urinary bladder

Classification: 

Classification Based on Location : External hernia – Ventral H, Inguinal H, Umbl . H, Perineal H Internal Hernia – Diaph . H Based on functional alterations: i ) Reducible ii) Irreducible – incarcerated H strangulated H

Classification: 

Classification III. Based on hernial contents i ) Enterocoele – intestines ii) Epliplocoele – Omentum iii) Reticulocoele – reticulum iv) Vesiculocoele – urinary bladder IV. Based on cause i ) Congenital – anatomical variations ii) Acquired – trauma

Treatment:: 

Treatment: Reduction of contents and application of bandages for 2-3 weeks Local infiltration of irritants Herniorrhaphy – suturing of hernial ring Hernioplasty – covering the gap with mesh and suturing it Kelotomy – enlarging the hernial ring

Perineal hernia: 

Perineal hernia It is abnormal protrusion/ displacement of pelvic or abdominal viscera through the pelvic diaphragm into the region around the anus called the perineum. It occurs when the perineal muscles separate, allowing the rectal, pelvic or abdominal contents to displace. It is common in dog and un common in ruminants but has been recorded in cattle and buffaloes This condition occurs secondary to a weakening of the muscles

Anatomy : 

Anatomy

Etiology : 

Etiology Cause of pelvic diaphragm weakening is poorly understood but is believed to be associated with male hormones Straining Congenital or acquired muscle weakness Atrophy Trauma

Diagnosis : 

Diagnosis History Affected animals usually are presented for treatment because of difficulty in defecation or urination Some owners notice swelling lateral to the anus Clinical signs Perineal swelling Constipation Dyschezia Tenesmus Rectal prolapse Stranguria Anuria Vomition Fecal incontenance

Differential diagnosis: 

Differential diagnosis Perineal neoplasia Perineal gland hyperplasia Anal sacculitis Anal sac neoplasm Perineal fistula Anal sac abscess Rectal neoplasia Anal trauma Anal dermatitis

Surgico-medicinal management: 

Surgico-medicinal management The goal of treatment is to relieve and prevent constipation, dysuria and organ strangulation Causative factors should be corrected Normal defection sometimes can be maintained using laxative , stool softeners , dietary changes , enema. Surgical management Herniorrhaphy should always be recommended.

Cont…..: 

Cont….. Castration is recommended during herniorrhaphy because it has been reported to reduce recurrence Non castrated dogs have a recurrence rate 2.7 times greater than castrated dogs.
