HERNIORRHAPHY AND SURGICAL OUTCOMES OF DIAPHRAGMATIC HERNIA IN CATS

Abstract

Abstract: The aim of this study was to evaluate the surgical outcome and mortality of diaphragmatic hernia in cats and present herniorrhaphy results. Diagnostic and surgical data from 25 cats with diaphragmatic hernias were analyzed retrospectively. The cats were between the ages of 2 months and 4 years, included 9 cases of males (5/9 neutered) and 16 cases of females (9/16 spayed). acute cases were 12/25 and chronic cases were 13/25. Diaphragmatic rupture locations were defined according to the points that are determined based on a clockwise scale. Location was classified as multiple in 10 (40 %), ventral in 7 (28 %), right in 5 (20 %), and left in 3 (12 %) cases. The three most frequently herniated organs were small intestine (20, 80 %), liver (16, 64 %), and omentum (15, 60 %). Postoperative survival rates were 83.3 % for acute cases and 69.2 % for chronic. Full recovery was achieved in 19 (76 %) of the cats. Results suggest that the location and size of diaphragm ruptures, the organs herniated, and the presence of concurrent pathologies directly affect mortality. Mortality is higher in cases with concurrent injuries, large diaphragmatic ruptures, and excessively herniated organs.Key words: prognosis; feline diseases; hernia; rupture; survivalHERNIORAFIJA IN KIRURŠKI IZIDI DIAFRAGMALNE KILE PRI MAČKAHIzvleček: Namen te študije je bil ovrednotiti kirurški izid in smrtnost diafragmalne kile pri mačkah ter predstaviti rezultate herniorafije. Retrospektivno smo analizirali diagnostične in kirurške podatke pri 25 mačkah z diafragmalno kilo. Mačke so bile stare od 2 mesecev do 4 let, med njimi je bilo 9 samcev (5/9 kastriranih) in 16 samic (9/16 steriliziranih). Akutnih primerov je bilo 12/25 in kroničnih 13/25. Mesta pretrganja diafragme so bila opredeljena glede na točke, določene na podlagi lestvice v smeri urinega kazalca. Pretrganje je bilo določeno kot večmestno v 10 (40 %) primerih, ventralno v 7 (28 %), desno v  5 (20 %) in levo v 3 (12 %) primerih. Trije najpogosteje vrinjeni organi so bili tanko črevo (20, 80 %), jetra (16, 64 %) in omentum (15, 60 %). Preživetje po operaciji je bilo pri akutnih primerih 83,3 %, pri kroničnih pa 69,2 %. Popolno okrevanje je bilo doseženo pri 19 (76 %) mačkah. Rezultati kažejo, da na umrljivost neposredno vplivajo mesto in velikost raztrganine diafragme, vrinjeni organi in prisotnost sočasnih patologij. Smrtnost je večja pri sočasnih poškodbah, velikih raztrganinah diafragme in prekomernem vrinjenju organov.Ključne besede: prognoza; bolezni mačk; kila; raztrganina; preživetje
