Outcome of surgical treatment of perineal hernia in cats: 36 cases (2013‐2019)

Abstract

To report the clinical presentation, complications, and long-term outcomes of cats treated for perineal hernia with modified internal obturator muscle transposition. MethOds:The medical records of cats surgically treated for perineal hernia between 2013 and 2019 were reviewed and an owner questionnaire was conducted to determine long-term outcome.Results: Thirty-six cats were included in the study: 34 had bilateral and two unilateral hernias. Of these 36, 24 (67%) were male neutered with a median age of 10 (range: 1 to 18) years. The complication rate was low, however, one cat experienced a major postoperative complication: rectal prolapse requiring revision surgery 48 hours postsurgery. Short-term outcomes were available for 32 of 36 (89%) cats. Of the 32, 23 were examined 6 weeks postoperatively, and a telephonic consultation was performed for an additional nine of 32. Of the 23 cats examined directly, none had recurrence. Overall 12 of 32 experienced short-term postoperative tenesmus which resolved in nine of 12 (75%). Long-term outcomes were available for 31 of 36 cats (86%), with a median of 18.5 (6 to 89) months follow-up. A good outcome was achieved in 23 of 31 (74%) whereas three of 31 (10%) had fair outcomes and five of 31 (16%) had a poor outcome. Of the five cats with a poor outcome, two required subtotal colectomy to manage clinical signs related to megacolon, two were euthanised following a return of clinical signs, and one developed unilateral recurrence.clinical significance: Perineal hernia should be considered in cats presenting with tenesmus or recurrent obstipation. Surgical treatment of perineal hernias in cats can result in good owner-assessed longterm outcome.

Ultrasound Morphology of Presumed Normal Anal Sacs in Dogs and Cats

“…The detected adverse finding was perineal pathology found in 8% of dogs, where the perineal hernia (36.4%) and urethrolithiasis (36.4%) were overrepresented. It should be noted that ASD might be the underlying cause of perineal hernia in dogs and cats [ 32 , 33 ]. Further studies would be necessary to evaluate the incidence of perineal hernias in dogs and cats with ASD.…”
