“…Assim como o observado neste estudo e relatado por outros autores, a hérnia perineal acomete quase que exclusivamente cães, machos, geriátricos e não castrados [4][5][6]. Sendo incomum em cadelas [11,12] e gatos [7,22]. Alguns autores relatam que essa menor incidência em cadelas se deve às diferenças anatômicas no músculo elevador do ânus, ligamento sacrotuberal e na formação estrutural do colágeno nas fêmeas [9,11].…”

“…A fisiopatologia da doença não é completamente entendida, mas acredita-se estar relacionada à exposição prolongada a hormônios sexuais masculinos, o que também pode justificar a maior prevalência de hérnia perineal em cães não castrados (85,83 %) [Tabela 1]. O esforço excessivo para defecação, fraqueza e atrofia da musculatura perineal e o trauma direto na musculatura também são fatores que podem causar a hérnia perineal [11,12].

Background: Perineal hernia is a serious disease characterized by weakening or atrophy and separation of the muscles and fasciae of the perineal musculature, followed by the caudal displacement of pelvic and abdominal organs to the perineum region. Treatment is invariably surgical and several approaches have been proposed, but complication and recurrence rates remain high. This study aimed to evaluate 120 cases of perineal hernia treated at the Veterinary Hospital of Uberaba (HVU) from 2005 to 2020, addressing the clinical and surgical aspects and the postoperative period, seeking to identify the most relevant factors to improve care and treatment of future patients affected by this disease.Materials, Methods & Results: The medical records of dogs with a definitive diagnosis of perineal hernia were collected. The prevalence of perineal hernia was calculated. Data were obtained regarding sex, being castrated or not, age, body mass, race, clinical signs, affected side, possibility of hernia reduction, treatments used, associated pathologies. Of the 120 cases, only 69 underwent surgery at the HVU and from these cases data were obtained regarding hernia content, surgical techniques, surgical wires used, recurrences and postoperative complications. Fisher's exact test was applied to assess the influence of the type of surgical treatment and surgical thread on the occurrence of complications and recurrences. Perineal hernia was the second most frequently observed hernia. Mixed breed, male, non-neutered and geriatric dogs were the most affected. The most frequently observed clinical signs were related to the digestive and urinary tract, consistent with the most commonly found hernia contents (bladder, prostate and rectum). The simple herniorrhaphy technique was the most used and showed a high number of complications. The second most used technique was the elevation of the internal shutter, which proved to be more efficient than the simple technique. Regardless of the technique used, the association of two or more techniques proved to be more efficient to reduce major complications. The use of the vaginal tunic stood out because it proved to be efficient in the treatment of perineal hernias regardless of whether it is associated with simple herniorrhaphy or obturator elevation. The surgical fixations of abdominal organs (Bladder, Ducto deferente and Colon) proved to be effective, since there were no recurrences or major complications associated with their use and the most used threads for herniorrhaphy were polyamide and catgut. Low recurrence rates were found in patients who received synthetic yarns. The most frequent complications were suture dehiscence and serous secretion.Discussion: Perineal hernia is a very important alteration due to difficulties in treatment, high rates of complications and recurrence, in addition to the large number of affected dogs. Several surgical techniques have already been proposed for the treatment of perineal hernia in dogs and are based on the reconstruction of the perineal musculature through sutures, muscle flaps, biological membranes, synthetic mesh and the reduction of pressure on the perineum through the surgical fixation of organs abdominals such as colon, vas deferens and bladder (in the musculature of the abdominal wall). It is concluded that the perineal hernia affects mainly male, non-neutered and geriatric dogs, being rare in females. Regardless of the techniques used, the association of two or more techniques is more efficient to reduce the rate of recurrences and complications. The autogenous vaginal tunic is a good option for muscle strengthening in perineal herniorraphies. The use of synthetic surgical wires leads to better results in the treatment of perineal hernia when compared to biological wires.

“…Castration performed at the time of the PH repair causes the prostate gland to atrophy within 2-3 weeks. Increased prostate size is related to constipation, which may result in rectal sacculation/diverticulum and PH recurrence ( Hosgood et al., 1995 ; Snell et al., 2015 ; Hayashi et al., 2016 ).…”

In an effort to reduce shelter intake, Miami-Dade Animal Services (MDAS) Pet Retention Program offers caretakers with an opportunity to have animals treated for certain medical conditions, free of charge. Discovery of new, simple surgical techniques for low-cost procedures provides veterinarians with more surgical solutions, expands the capacity for services provided through low-cost veterinary clinics and other shelter programs, and provides shelters with life-saving alternatives that will increase adoptability of homeless pets and reduce euthanasia rates. The aim of this clinical trial was to describe and to evaluate the use of the autologous tunica vaginalis communis as a free graft to repair perineal hernia (PH) in intact male dogs at an animal shelter facility. In 2018, seven male intact dogs, diagnosed with perineal hernias (PH), were presented to MDAS. All dogs had the surgical reconstruction of the pelvic diaphragm repaired by using the tunica vaginalis communis obtained at the time of castration, prior to the perineal access, and sutured directly into the perineal defect. Clinical outcome including postoperative complications and hernia recurrence were obtained via telephone communication. The median follow-up time was 13 months. None of the dogs included in this study had recurrence of the PH. All dogs were adopted, were transferred to animal rescue organizations or were returned to their owners after the surgical procedure. The use of tunica vaginalis communis autograft is a simple, low-cost surgical technique that requires less surgical expertise and training and can be used for perineal herniorrhaphy in dogs, without long-term recurrence.

“…Williams (2009) menyatakan kasus hernia perineal dapat terjadi pada anjing dan kucing namun paling sering terjadi pada anjing. Hayashi et al (2016) hernia perineal, 94% terjadi pada anjing jantan dan 4% tejadi pada anjing betina. Faktor komorbid terkait hernia perineal pada anjing betina antara lain trauma pada panggul, batuk persisten sekunder akibat bronkitis, kolaps trakea dan cardiopathy (anjing berukuran kecil).…”

Bedah Reposisi Hernia Perineal pada Kucing Betina

et al. 2020

View full text Add to dashboard Cite

Kucing betina berusia ±1 tahun dengan gejala klinis dysuria, konstipasi, pada bagian perineal terdapat kebengkakan dengan konsistensi kenyal disertai luka. Hasil pemeriksaan darah menunjukkan peningkatan monosit sedangkan hasil pemeriksaan ultrasonografi pada kebengkakan menunjukan gambaran anechogenic berisi cairan. Hasil aspirasi teridentifikasi cairan tersebut adalah urin, sehingga kucing tersebut dapat didiagnosis hernia perineal dengan refleksi vesika urinaria. Tahapan operasi meliputi herniorraphy, reposisi vesika urinaria, dan hernioplasti. Terapi sistemik pasca operasi yaitu Amoxicilin 20 mg/kgBB q12h, Asam mefenamat 16 mg/kg BB q12h, dan multivitamin ½ tab q12h selama tujuh hari. Terapi menggunakan topikal menggunakan povidone iodine 10% dan die da yao jing®. Kucing menunjukkan aktifitas normal setelah 7 hari perawatan.
