Resumo(s)
Hérnias inguinais ocorrem quando uma víscera, normalmente intestino delgado, atravessa o
anel inguinal e entra no saco vaginal. O encarceramento desse segmento é doloroso e pode
levar a isquémia do mesmo. Representam até 4% dos casos de cólica. O diagnóstico pode
ser confirmado por palpação escrotal ou retal ou ecografia escrotal. A redução da hérnia
pode ser manual ou cirúrgica através de laparotomia. Estas hérnias podem ser prevenidas
quer através de castração quer com uma redução dos canais inguinais por via
laparoscópica. Os casos de cólica por hérnia inguinal no hospital de cavalos da FMV -
ULisboa em Portugal foram revistos e analisados. De 23 casos referenciados e admitidos,
19 chegaram ao hospital com hérnia patente. 13 foram reduzidos manualmente e 6 após
laparotomia. A taxa de mortalidade foi de 4,6%. O tempo e custos de internamento foram
consideravelmente menores nos pacientes que apenas necessitaram de redução manual.
Foram castrados preventivamente 10 pacientes, e outros 4 foram submetidos a redução dos
canais inguinais por laparoscopia. Tiveram alta hospitalar 91% dos pacientes e o
encerramento dos canais inguinais permitiu evitar recidiva em todos, com prova de
fertilidade em 75%.
ABSTRACT - EQUINE INGUINAL HERNIA – 23 CASE REVIEW - Inguinal hernias happen when some viscus enters the vaginal sac trough the inguinal ring, usually small intestine. Once there the small intestine loop may become incarcerated and cause pain. Inguinal hernias make up until 4% of colic cases. Diagnosis is confirmed either by rectal or scrotal palpation or by scrotal ultrasound. Hernia reduction can be manual or surgical trough laparotomy. These kind of hernias can be prevented either by castration or by laparoscopic inguinal ring reduction. Colic caused by inguinal hernia cases from the FMV – Ulisboa Equine Hospital in Portugal were reviewed and analyzed. From 23 referral cases 4 solved before admission and 19 arrived at the hospital with the hernia. 13 were manually reduced and 6 needed laparotomy. Mortality rate was 4,6%. Hospitalization time and costs were considerably lower for patients who only needed manual reduction. 10 patients were preventively castrated and other 4 had their inguinal rings reduced trough laparoscopy. Discharge rate was 91% and the inguinal ring closure prevented relapse in all cases with fertility proof in 75% of them.
