90 REMEDIATION OF HEMORRHAGIC ACCIDENTS DURING LAPAROSCOPIC CASTRATION OF SOWS Catalin MICSA, Dorin TOGOE, Andrei TANASE, Alexandru SONEA Faculty of Veterinary Medicine Bucharest, 105 Splaiul Independenţei, 050097, Bucharest, Romania; Corresponding author: tel +40721122908; email: mcscatalin@yahoo.com Abstract Laparoscopic surgery gained a lot of field in human and veterinary medicine, replacing succesfully many invasive surgical techniques. Laparoscopic surgery presents several medical advantages, but equally has a high risk of bleeding accidents (rupture of the vascular pedicle, incorrect ligation or application of vascular clamps). The aim of the study was to illustrate the way to remedy this intraoperatory accidents. Research was carried out on 5 sows that were ovariectomized laparoscopically as an experimental model for human medicine. For addressing these accidents, it can be intervened with lavage (irrigation-aspiration), individualization of the vascular pedicle, pressure and clamping with metal clips or external ligatures in order to completely stop the bleeding. Our study showed the real capacity of this methods to control small and medium intensity haemorrhages, without having a negative impact on surgery outcome and recovery period. Key words: laparoscopy, bleeding, ovariectomy. INTRODUCTION Laparoscopic hysterectomy has been found in humans to reduce postoperative pain, blood loss, duration of hospital stay, time to return to normal gastric motility, and recovery times when compared to open hysterectomies. Minimally invasive surgical procedures are gaining favor based on their demonstrated advantages to open procedures. As the benefits of minimally invasive surgery are more widely recognized by veterinarians and their clients, laparoscopic sterilization is growing in popularity. Laparoscopic ovariectomy and ovariohysterectomy procedures are associated with less postoperative pain and a faster return to normal activity versus open sterilization procedures. The advent of newer laparoscopic electrocoagulation devices has further increased the technical feasibility and popularity of these procedures. With the developments achieved in recent years in laparoscopic surgery, the field has acquired a host of new techniques to achieve haemostasis, allowing the surgeon to approach complex procedures. These techniques include physical modalities (as simple as compression or suturing and as sophisticated as endovascular staples), or thermal modalities (such as bipolar coagulation, laser or ultrasonic dissectors). It is up to the laparoscopic surgeon to be familiar with all these different modalities and their proper use and limitations. It should also be kept in mind that the best approach to haemostasis in laparoscopy is prevention by thorough case preparation and meticulous dissection technique. MATERIALS AND METHODS The study we are presenting here was carried out at the Faculty of Veterinary Medicine, in the clinic of Obstetrics and Gynaecology, Bucharest. Five female intact swine with body weight range from 30 to 100 kg were brought to the centre. Ages were approximated based on dental eruption and wear and ranged from 3 months to 12 months. The pigs were determined to be healthy by physical examination before surgery. To minimise the stress, animals were premedicated with Ketamine and Xylazine administered intramuscular, prior to transfer to the operating room. Animals arrived in a somnolent condition and were carefully protected against hypothermia. Then were Scientifc Works. Series C. Veterinary Medicine.
