Histological changes in the rabbit ovary following CO2 and argon laser vaporization

This study was designed to explore the correlation between the naked eye effect and the extent of histological damage following either CO2 or argon laser cauterization of the rabbit ovary, as well as to compare the two lasers regarding the histological effect. The study included 12 mature female New Zealand rabbits. From each rabbit, one ovary was taken as a control, and the other was exposed to either CO2 [pulsed or continuous mode] or argon laser. The ovaries were then excised and examined for histological changes. At all the used settings, both lasers produced the same naked eye appearance. Histologically, CO2 laser produced deep effects only with a wide crater of capsule injury. Pulsed argon laser produced the deepest thermal effect with narrow entry area on the capsule, suggesting less injury to capsular and sub-capsular regions. It is concluded that pulsed argon is superior to CO2 laser in laser ovarian coagulation surgery, due to deep effect, and less surface injury minimizing the possibility of adhesions. This is of particular importance when laser ovarian cauterization is intended for PCOS

Laparoscopic hysterectomy versus vaginal hysterectomy

This study included 102 patients planned for hysterectomy. The age range was 39 to 51 years. The aim of the study is to compare laparoscopic total hysterectomy to vaginal hysterectomy. 60 cases were chosen for laparoscopic hysterectomy all of them were successful except 2 cases undergone abdominal hysterectomy due to extensive bleeding encoumtered during the operation, and 42 patients undergone vaginal hysterectomy. The operation time for the vaginal hysterectomy was significantly shorter than that of the total laparoscopic hysterectomy.The Blood loss was less with the vaginal hysterectomy compared to the laparoscopic total hysterectomy. The full recovery time was shorter for the vaginal hysterectomy, compared to the laparoscopic total hysterectomy. The Hospital stay and the retum to sexual function were the same for both types of hysterectomy. Pain was the onIy complication encountered in the group who undergone vaginal hysterectomy, accounting for 50% of cases. It was moderate and lasted for a maximmn of 10 days. Laparoscopic hysterectomy was accompanied by abdominal discomfort, shoulder tip pain, and lower abdominal stretch, sequelae of pneumoperitoneum. We conclude that, whenever possible, vaginal hysterectomy is a leading choice. However, in cases of extensive pelvic adhesions, stage III and IV of endometriosis, large ovarian endometriomata >5 cm in diameter and in postmenopausal women with short fornices, laparoscopic total hysterectomy is another good choice, which has minimal complications when performed by trained surgeons

Trace elements in gynecologic malignancies

Serum levels of copper, zinc, iron and manganese, as well as copper/zinc ratio were evaluated in normal controls and in patients with cancer cervix, ovary or endometrium. In all cancer patients studied, the mean serum level of copper and zinc was found to be significantly elevated above control level. The mean serum manganese was found to be significantly elevated above control in cancer cervix and endometrium, but not significantly so in cancer ovary patients. The mean serum iron was found to be significantly lower in patients of the three malignancies examined compared to the control group. A serum level of copper/zinc >2.02 completely separated cases of cancer ovary, cervix and endometrium from controls
