INTRACORPOREAL KNOT TYING TECHNIQUE FOR OVARIAN PEDICLE LIGATION IN DOGS – A CLINICAL STUDY

Abstract

The present paper describes the technique of laparoscopic intracorporeal knot tying (surgeon’s knot) for ovarian pedicle ligation in dogs subjected to ventral midline 3-portlaparoscopic ovariectomy. The technique of intracorporeal knot tying was studied in twelve female dogs presented to the surgery unit of the Teaching Veterinary Clinical Complex Pookode, for laparoscopic birth control. A ventral midline three port technique was employed. The ovary was anchored to the abdominal wall in an elevated position using suspension sutures, to facilitate ligation and resection. Two needle holders were introduced – one through the cranial and the other through the caudal instrumental ports for knot tying. A No. 1 braided silk suture of 12 cm length was used for applying intracorporeal flat surgeon’s knot. The mean time from introduction of suture to placement of secured flat square knots on the left ovary was 17.857±5.2418 minutes and on the right ovary was 20.714±4.7157 minutes. It was found that the suture length of 12 cm was found suitable for easy manoeuvrability. Intracorporeal ligation ensures more haemostatic competency inspite of its complexity. It is believed that this procedure needs a long learning curve and if mastered, this technique is simple and cost effective.
