Methods of laparoscopic sterilization of bitches

At present the question of sterilisation of bitches with the aim of inducin g permanent sterility is paid much attention. So far preferred techniques h ave required surgical intervention per laparoscopiam. In this submitted stu dy we focused on using laparoscopy at sterilisation of bitches in three way s: by creating mechanical occlusion of oviducts using endo-stapler techniqu e (n = 3), by forming oviduct occlusion by electrocoagulation with the aid of endo-coagulator (n = 3), by performing ovariectomy using modified endo-s uture technique (n = 2). At the interventions effectiveness, complications and difficulty were observed. The effect of laparoscopic intervention on re productive apparatus and condition of the patient was observed as well. Pat ients (n = 8) of German shepherd breed aged 2-7 years were included in the evaluation. Interventions were performed with the aid of two MLW Germany la paroscopic units with 180 degree angle and 0.5-1 cm working diameter. Elect rocoagulation was carried out with Eltom, Chirana Slovakia, equipment. Occl usions of oviducts were performed with endo-stapler titanium clip applicato r. Ovariectomy was carried out with the aid of extracorporal Orsilon techni que with non-traumatic units. We have found that it is possible to make a p ermanent occlusion of oviducts by placing one or two clips on the left or r ight oviduct concerned. The intervention lasted 20-30 minutes. By using ele ctro-coagulation of oviduct 1-2 occlusions were made on each oviduct. The o cclusion of oviducts by endo-coagulation took 10 minutes. At ovariectomy tw o ligatures were applied cranially to the ovary and a single ligature cauda lly from the same ovary. The ovary was removed with endoscissors. The whole endoprocedure in both ovaries took 70 minutes. In comparison with similar laparoscopic interventions the above described techniques have certain adva ntages. The result of abdominal cavity perforation is just small wounds whi ch require 2 deep and 2 superficial sutures at the most. As the interventio ns are relatively simple, they can be performed on older patients as well. Small laparoscopic incisions contribute to a considerable decrease of posto perative pain in surgical wound.
