Laparoscopic Vasectomy vs Laparoscopic Sterilization in Dogs: A Comparison of Two Techniques

Abstract

Twelve clinically healthy, adult male dogs randomly equally divided into two groups (I and II). Animals of both the groups received xylazine-ketamine anesthesia. Laparoscopic bilateral vasectomy was performed in group I, whereas in animals of group II in additition to vasectomy, spermatic artery-vein plexus were clipped with titanium clips at a distance of 1 to 2 cm. Insufflation of abdominal cavity was achieved by CO2 (2 liter/minute) at 10 mm Hg pressure gradient. Clinical observations revealed no significant changes. Differential leukocyte count (DLC) revealed significant neutrophilia and comparative lymphopenia on 3rd postoperative in both groups. Significant increase (p 0.05) up to 7th postoperative day in animals of group II. On the basis of the parameters studied, it can be concluded that capnoperitoneum at 10 mm Hg pressure gradient and CO2 at the flow rate of 2 liter/minute provides optimum visualization of intra-abdominal organs and found suitable for laparoscopic sterilization in male dogs. The laparoscopic vasectomy alone in male dogs was found comparatively quick, less time consuming and can be successfully applied for mass sterilization program. Oxidative stress in laparoscopic vasectomy (group I) was less as compared to other group.
