Inverted ovariosalpingohisterectomy technique in cats: advantages and limitations / Técnica de ovariossalpingohisterectomia invertida em gatas: vantagens e limitações

The inverted ovariosalpingohysterectomy (OSH) technique involves initial uterine removal, followed by ovarian disinsertion. The objective of this study was to compare the inverted technique with the traditional technique, characterized by initial removal of the ovaries followed by uterine resection, for evaluating the performance of the inverted OSH technique in cats. For this, 24 healthy, female cats, aged between 7 months and 5 years, with a body condition score of up to 6 points (9-point scale), divided into two equal groups: the traditional technique (TT) and the inverted technique (IT). Procedures were performed by the same veterinarians (surgeon and their assistant) as well as semi-quantitative analysis of the techniques (questionnaire related to the ease of uterine and ovarian manipulation as well as of intestinal and urinary vesicle manipulation) and descriptive qualitative analysis (technical report with the opinion of surgeons and an external evaluator). In addition, the total surgical time and positive pain response were evaluated, indicated by the changes in vital parameters observed by the anesthesiologist during surgery. Inverted technique it promoted greater ovarian exposure, allowing uterine cranial flexion to perform the ligatures, thus facilitating their manipulation, hemostasis, and section of the pedicle. Free the uterus from its ligaments to the abdominal cavity allowed greater mobilization of the conjoint. Both techniques required short operation time (average time of 16’± 1.321’ in the IT group and 15’± 0.525’ in the TT group). The presence of algetic stimulus was similar in the techniques, three animals in each group suffered analgesic rescue.

A técnica de ovariossalpingohisterectomia (OSH) invertida envolve a remoção inicial uterina seguida da desinser-ção ovariana bilateral. O objetivo deste estudo foi comparar a técnica invertida com a tradicional, caracterizada pela remoção inicial dos ovários seguida da ressecção uterina, a fim de avaliar aspectos de execução da OSH Invertida em gatas. Para isso, 24 felinas hígidas, com idade entre 7 meses e 5 anos, com escore de condição corporal até 6 pontos (escala 9 pontos), foram divididas em dois grupos iguais (TT- técnica tradicional e TI- técnica invertida). As cirurgias e anestesias foram efetuadas pelos mesmos médicos veterinários, as técnicas foram avaliadas pelo cirurgião e auxiliar por análises semiquantitativa (questionário com escores relativos à facilidade de manipulação uterina e ovariana, nível de manipulação do intestino e vesícula urinária) e qualitativa descritiva (relatório das técnicas com opinião dos cirurgiões e avaliador externo). Ainda, avaliou-se o tempo cirúr-gico total e a indicação de resposta álgica positiva conforme mudanças nos parâmetros vitais no transoperatório. A OSH inver-tida nos felinos não revelou diferença estatística na análise semiquantitativa quando comparada à técnica tradicional. Porém, promoveu maior exposição ovariana permitindo a flexão cranial uterina, facilitando sua manipulação, hemostasia e secção do pedículo. Ainda, a liberação do útero dos ligamentos à cavidade abdominal permitiu maior mobilização do conjunto. Ambas as técnicas revelaram-se de rápida execução sendo a média de tempo no TI de 16’±1,321’, e no TT de 15’±0,525’. A presença de estímulo álgico foi semelhante nas técnicas havendo resgates analgésicos em três animais de cada grupo.

Ovariosalpingohysterectomy technique adapted in bitches (Canis familiaris): advantages and limitations

Background: The ovariosalpingohysterectomy (OSH) is one of the most performed surgeries in bitches often used in population control. Surgical techniques that decrease the chances of operative complications and cause less nociceptive stimulation and acute pain to the patient are highly sought after by veterinarians. We evaluated the inverted OSH technique (IT), which, after celiotomy, begins with the ligature execution, transection of the uterine body and subsequent ligation and ovarian disinsertion. The purpose of this investigation was to analyze aspects of IT execution in bitches, such as visceral manipulation, access to the uterus and ovaries, and surgical time compared to the traditional technique. Materials, Methods & Results: Inverted OSH was compared to the so-called traditional OSH technique, characterized by the initial removal of the ovaries followed by uterine section. The OSH techniques were performed in 24 healthy animals, with a body condition score of up to six (on a nine-point scale) in dogs aged between seven months and five years. All dogs were from the Birth Control Program of Dogs and Cats of the UFRRJ and were distributed into two groups: traditional technique (TT) and inverted technique (IT). Surgeries and anesthesia were carried out by the same veterinarian crew (surgeon, surgical assistant, and anesthesiologist). OSH techniques were evaluated by the surgeon and surgical assistant using semiquantitative analysis (multiple-choice questionnaire with closed questions that pointed scores related to the ease of uterine and ovarian manipulation, as well as to the level of manipulation of the intestinal and urinary vesicle) and qualitative descriptive methods (report of techniques with the opinion of surgeons and an external evaluator-veterinarian surgeon who attended surgeries). Also, the total surgical time and the indication of a positive analgesic response according to changes in the vital parameters observed by the anesthesiologist during specific moments of the operation were…(AU)
