Laparoscopic Anatomy of the Abdomen and Laparoscopic Ligating Loops, Electrocoagulation, and a Novel Modified Electroligation Ovariectomy in Standing Mare

摘要

The purpose of this study was to provide a detailed laparoscopic anatomy of the caudal abdominal region of mare in a standing position and to evaluate and modify a technique for standing laparoscopic ovariectomy using combination between hand-tied ligating loop and electrocoagulation techniques, as the ligating loops, electrocoagulation, and modified electroligation laparoscopic ovariectomy were applied using nine adult mares. Laparoscopy was practical and effective for direct visual examination of internal abdominal organs in the mare. Ventral dislocation of abdominal viscera after pneumoperitoneum was established with the mare in standing position, which provided an excellent inspection of the dorsal and ventral structures in the peritoneal cavity on the right and left sides. Standing laparoscopic ovariectomy using an electroligation modified method was considered a safe and effective method for hemostasis of the mesovarium, technically easy, time saving, and economical. The mean surgical time for bilateral ovariectomy was 40 +/- 7.63, 60 +/- 5.25, and 85 +/- 6.43 minutes for electroligation-modified technique, ligating loops technique, and electrocoagulation technique, respectively.
