Introduction

It is clear that in case of pathology of the reproductive tract, ovariohysterectomy is the technique of choice if surgical management is indicated; however, in the case of healthy females, in which an elective sterilization is performed, the real need to carry out ovariohysterectomy is not clear, and the question remains whether ovariectomy could be a reliable and acceptable method to replace ovariohysterectomy as the method of choice.

Literature Review

The first approach to this dilemma was published by van Goethem et al. (2006), who found no significant differences between the two techniques, and concluded that ovariectomy can replace ovariohysterectomy as the method of choice in the case of elective surgery. Since then, there have been some studies (Peeters, Kirpensteijn 2011; Bender 2012; Harris et al. 2013) in which different aspects of the surgical technique and patient recovery were compared, always leading to the conclusion that ovariectomy is as safe and effective as ovariohysterectomy. DeTora and McCarthy (2011) question the fact that in the United States ovariohysterectomy is considered the standard procedure, regardless of the evidence suggesting that ovariectomy could be the procedure of choice.

Conclusions

Evidence suggests that both techniques are acceptable, and that the selection of the technique is based more on tradition in certain geographical areas (America: ovariohysterectomy; Europe: ovariectomy) than in solid evidence of advantages of one technique over the other. Evidence also suggests that ovariectomy can replace ovariohysterectomy to spay healthy female dogs and cats.

¿Ovariohisterectomía u Ovariectomía? ¿Evidencia?

Introducción

Es claro que en caso de existir patología del tracto reproductivo, la ovariohisterectomía es la técnica de elección en caso de indicarse manejo quirúrgico; sin embargo, en el caso de hembras sanas, en las cuales se desea llevar a cabo una esterilización electiva, no es clara la verdadera necesidad de llevar a cabo ovariohisterectomía, y sigue existiendo la pregunta de si la ovariectomía puede ser un método confiable y aceptable para reemplazar la ovariohisterectomía como método de elección.

Revisión de Literatura

La primera aproximación a este dilema fue publicada por van Goethem et al. (2006), encontrando que no existen diferencias significativas entre las dos técnicas, y que la ovariectomía puede reemplazar a la ovariohisterectomía como método de elección en el caso de cirugía electiva. Desde entonces se han realizado algunos estudios (Peeters, Kirpensteijn 2011; Bender 2012; Harris et al. 2013) en los que diferentes aspectos de la técnica quirúrgica y la recuperación del paciente son comparados, llegando siempre a la conclusión que la ovariectomía es tan segura y efectiva como la ovariohisterectomía. DeTora and McCarthy (2011) cuestionan el hecho que en los Estados Unidos la ovariohisterectomía sea considerada el procedimiento estándar, sin tener en cuenta que la evidencia sugiere que la ovariectomía podría ser el procedimiento de elección.

Conclusiones

La evidencia permite afirmar que ambas técnicas son aceptables, y que la selección de la técnica se basa más en la tradición en determinadas zonas geográficas (América: ovariohisterectomía; Europa: ovariectomía) que en evidencias sólidas de ventajas de una técnica sobre la otra. La evidencia también sugiere que la ovariectomía puede reemplazar a la ovariohisterectomía para esterilizar de hembras caninas y felinas sanas.
