Effect of laparoscopic adrenalectomy on estrogen, progesterone and cortisol hormones in bitch

The effect of laparoscopic left adrenalectomy on adult bitches ' estrogen, progesterone, and cortisol levels was studied. Fifteen adult stray bitches were used. The average weight was 20 kg, age was 27 months. The study animals were randomly divided equally into three groups, each group containing five bitches. The first group underwent unilateral laparoscopic left adrenalectomy (ULLA), the second group underwent left adrenalectomy with bilateral ovariectomy, and the third group was left as a control group. Blood samples were taken from all animals on days 0, 7, 14, and 30 after surgery to estimate estrogen, progesterone, and cortisol levels. The result of using sternal decubitus laparoscopic left adrenalectomy was a practical, feasible, and rapid technique with a short average surgical time of 72 minutes and easy dissection; therefore, it is considered a standardized technique. The results also showed that the estrogen concentration on the 30th day of the three groups was 141.2, 56.8, and 137.8, respectively, with a significant difference in the second group compared to the rest groups and the progesterone concentration on the 30th day of the three groups was 3.8, 3.6 and 4.5 respectively with a significant difference among the groups, and in another context the cortisol concentration on the 30th day of the groups was 128.4, 82 and 129, respectively, with a significant difference in the second group compared to the rest groups. In conclusion, the possibility of laparoscopic adrenalectomy with sternal recumbency in dogs is a standardized method, and unilateral adrenalectomy does not affect the levels of estrogen, progesterone, and cortisol due to the compensation mechanism.
