Abstract
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.
Highlights
Ovariosalpingohysterectomy (OSH) is the surgical technique for excision of the uterus, ovaries, and fallopian tubes and corresponds to the most commonly performed abdominal surgery in veterinary medicine (MIGLIARI; DE VUONO, 2000; DEL CARLO; BORGES, 2018)
Such surgery consists of the initial ligatures of the middle uterine arteries and transection of the uterine body followed by ligation of the ovarian arteriovenous complex and bilateral ovarian resection, the opposite of what is considered as the traditional technique in the literature by the authors (MACPHAIL, 2014; DEL CARLO; BORGES, 2018)
The patient who required additional hemostasis weighed only 2.1 kg and was young; the small size of her viscera and her immature body development may have facilitated uterine rupture under traction, since pediatric tissues are more fragile compared to adults and handling it requires more caution (MACPHAIL, 2014; FIGUEIREDO, 2011)
Summary
Ovariosalpingohysterectomy (OSH) is the surgical technique for excision of the uterus, ovaries, and fallopian tubes and corresponds to the most commonly performed abdominal surgery in veterinary medicine (MIGLIARI; DE VUONO, 2000; DEL CARLO; BORGES, 2018). This study aimed to analyze and extend the application of the inverted OSH technique previously described in bitches to the feline species (CAMPOS et al, 2020). Such surgery consists of the initial ligatures of the middle uterine arteries and transection of the uterine body followed by ligation of the ovarian arteriovenous complex and bilateral ovarian resection, the opposite of what is considered as the traditional technique in the literature by the authors (MACPHAIL, 2014; DEL CARLO; BORGES, 2018). The OSH technique, as a basis for the traditional pattern in the current study, used only hemostatic forceps distal to the ovary, previously positioned before the ligation of the ovarian arteriovenous complex (DÁVID; KASPER, 2000)
