Laparoscopic oophorectomy in bitches

A clinical study on laparoscopic oophorectomy in bitches was conducted to compare two different modalities viz., electro-cautery (Group I; n=6) and endo-looping (Group II; n=6). The anesthetized bitches were placed on a specially designed tilting wooden table for better and easy laparoscopic manoeuvrability. Three peri-umbilical midline ports were created for lodging two 5 mm hand instruments and laparoscope following abdominal insufflation. The electrocautery was performed using monopolar current for electro-desiccation and the endo-looping was carried out using black braded silk no. 1. The total time required to perform laparoscopic oophorectomy by electro-coagulation was comparatively lesser (31.53±0.9 min) than endo-looping (34.24±0.64 min). Effect of anaesthesia and bleeding during the procedures were reflected by transient reduction in total erythrocyte count, haemoglobin concentration and packed cell volume. The acute inflammatory changes following laparoscopic procedures led to increase in total leucocyte count and a compensatory fall in the numbers of lymphocytes. An early and uneventful recovery of all the animals following both the laparoscopic procedures was credited to minimum invasive nature of the procedures. The stress induced by laparoscopic procedure led to temporary increase in serum cortisol level. Both the laparoscopic oophorectomy procedures were found to be effective but endo-looping required additional precision and perfection. The electro-coagulation followed by extraction of ovary may be preferred for wider clinical use.
