At present the question of sterilisation of bitches with the aim of inducing permanent sterility is paid much attention. So far preferred techniques have required surgical intervention per laparoscopiam. In this submitted study we focused on using laparoscopy at sterilisation of bitches in three ways: by creating mechanical occlusion of oviducts using endo-stapler technique (n = 3), by forming oviduct occlusion by electrocoagulation with the aid of endo-coagulator (n = 3), by performing ovariectomy using modified endo-suture technique (n = 2). At the interventions effectiveness, complications and difficulty were observed. The effect of laparoscopic intervention on reproductive apparatus and condition of the patient was observed as well. Patients (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 laparoscopic units with 180 degree angle and 0.5-1 cm working diameter. Electrocoagulation was carried out with Eltom, Chirana Slovakia, equipment. Occlusions of oviducts were performed with endo-stapler titanium clip applicator. Ovariectomy was carried out with the aid of extracorporal Orsilon technique with non-traumatic units. We have found that it is possible to make a permanent occlusion of oviducts by placing one or two clips on the left or right oviduct concerned. The intervention lasted 20-30 minutes. By using electro-coagulation of oviduct 1-2 occlusions were made on each oviduct. The occlusion of oviducts by endo-coagulation took 10 minutes. At ovariectomy two ligatures were applied cranially to the ovary and a single ligature caudally 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 advantages. The result of abdominal cavity perforation is just small wounds which require 2 deep and 2 superficial sutures at the most. As the interventions are relatively simple, they can be performed on older patients as well. Small laparoscopic incisions contribute to a considerable decrease of postoperative pain in surgical wound
