ABSTRACT
Procurou-se comparar duas técnicas de ovariosalpingohisterectomia (OSH): vídeo-assistida com dois portais e convencional em cadelas, ambas com o uso de equipamento Ligasure atlas®. Para tanto, foram utilizados 18 animais separados em dois grupos, sendo no primeiro grupo realizada a OSH por celiotomia e no segundo pelo acesso vídeo-assistido. Os procedimentos videocirúrgicos foram realizados por meio de dois trocartes dispostos nas regiões umbilical e pré-púbica, com os cães posicionados em decúbito dorsal. Em ambos os grupos, o único método de hemostasia empregado foi o Ligasure atlas®. Não houve diferença significativa acerca do tempo operatório, das complicações trans e pós-operatórias e das perdas sanguíneas. Conclui-se que a OSH vídeo-assistida com o uso de dois portais e Ligasure atlas® e a técnica convencional com o emprego do mesmo equipamento são rápidas, seguras e efetivas em cadelas.
In this study the authors compared two different procedures of ovariosalpingohysterectomy (OSH) in dogs. For that, 18 dogs were randomly assigned into 2 different groups: group I (GI) in which the OSH was performed by celiotomy and group II (GII) in which it was a video-assisted procedure using two portals positioned in the umbilical and pre pubic regions, under dorsal recumbence position. In both groups the method of hemostasis was the Ligasure atlas®. The authors did not observe significant differences between both methods for the surgical time or complications during and after the surgical procedure and blood loss. It was concluded that OSH using video-assisted surgery with two portals and the conventional technique, both using Ligasure atlas® are safe, fast and effective to be used in dogs.
ABSTRACT
OBJECTIVE: We evaluated the outcome of bipolar energy by using PlasmaKinetic cystoscope instruments in the treatment of urethral stricture and bladder neck contracture. MATERIALS AND METHODS: Twenty-two male patients with urethral stricture and five with bladder neck contracture were treated by endoscopic bipolar vaporization. The most common etiology for stricture formation was iatrogenic (85.2 percent) and the mean stricture length was 12.2 mm. All patients were evaluated with urethrography and uroflowmetry one month and 3 months after surgery. Urethroscopy was routinely performed at the end of the first year. Preoperative mean maximum flow rate (Q max) was 4.9 mL/s for urethral stricture and mean Q max was 3.4 mL/s for bladder neck contracture. The results were considered as "successful in patients where re-stenosis was not identified with both urethrography and urethroscopy. Minimum follow-up was 13.8 months (range 12 to 20). RESULTS: Tissue removal was rapid, bleeding was negligible and excellent visualization was maintained throughout the vaporization of the fibrotic tissue. Postoperative mean Q max was 14.9 mL/s and the success rate was 77.3 percent for urethral stricture at mean follow-up time of 14.2 months. The success rate was 60 percent with a mean follow-up time of 12.2 months for bladder neck contracture and the mean Q max was 16.2 mL/s, postoperatively. CONCLUSIONS: The study suggests that bipolar vaporization is a safe, inexpensive and reliable procedure with good results, minimal surgical morbidity, negligible blood loss, and thus, it could be considered as a new therapeutic option for the endoscopic treatment of urethral stricture and bladder neck contracture.
