Abstract
This study was conducted on thirty five apparently healthy mongrel dogs and five suffered unilateral cryptochidism. Their weight ranged between 5-20 k.g. This study was done at the department of Surgery, Anesthesiology and Radiology, Faculty of Veterinary Medicine, Zagazig University. Dogs were divided into four groups. Group A (laparoscopic anatomy) had evaluation of the laparoscopic abdominal anatomy and consisted of five dogs. Group B consisted also of five dogs suffered unilateral cryptorchidism in which, the feasibility of laparoscopic cryptorchidectomy was studied. Group C (laparoscopic surgery) was divided into three subgroups (C1, C2, and C3), each consisted of five dogs. Subgroup C1 had laparoscopic cystotomy, subgroup C2 had laparoscopic vasectomy and subgroup C3 had laparoscopic ovariectomy. Group D (open surgery) was divided into three subgroups (D1, D2 and D3), each consisted of five dogs. Subgroup D1 had open cystotomy, subgroup D2 had open vasectomy and subgroup D3 had open ovariectomy.
The laparoscope of 5.5 mm in diameter and 0 degree field of view was sufficient and useful in all laparoscopic interferences in this study. The 12 intraabdominal pressure gave sufficient space to work in.
Detailed laparoscopic anatomy was evaluated using three ports placed at ventral midline with the primary port placed just caudal to umbilicus and the two secondary ports placed cranial and caudal to it. Most aspects of the abdominal organs were visualized through the ventral midline approach. After trendlenburg positioning.
