This study was designed to evaluate the using of two laparoscopic techniques for repairing an experimental cystotomy of urinary bladder reinforced with omental pedicle in dogs. Eighteen local breed male dogs were randomly allocated into two equal groups: first group an experimental cystotomy (about 2 cm) was induced laparoscopically at the ventral surface of the urinary bladder, repaired with titanium clips and reinforced with the omental pedicle. In the second group: similar technique was followed; however, the induced was repaired with hand-assisted extracorporeal laparoscopic method. In both groups, several diagnostic parameters were followed including clinical / laparoscopic exploration, radiology, and ultrasonography. Results obtained in the first group shown the titanium clips 4-6 clips freely applicated and whole time consuming for performing operation was 45±2.1 minutes. Clinically, the experimental animals didn't show any abnormal changes in their behavioral activities. Radiographic examination revealed distention of the urinary bladder accompanied by the presence of distances between the titanium clips; however, ultrasonography didn't show any leakage or thickness at the site of operation. Laparoscopic examination demonstrated mild adhesion between urinary bladder and adjacent organ. In the second group, the operation required 36±1.1 minutes to be completed. Postoperatively, no signs of pain were observed, however, animals demonstrated post-operative transient hematuria, lasts for 24 hours, accompanied with severe adhesion between the bladder and abdominal wall. Radiographically, regular distention of the bladder was revealed, while ultrasonographic examination showed hyperechoic dots and thickening of the bladder wall. We concluded that the hand-assisted laparoscopic cystorrhaphy strengthened by omentum is a practical, time saving and mini-invasive surgical technique.

The aim of this study was to evaluate the effects of platelets rich fibrin and bone marrow on distal radial fracture healing in local breed dogs. Twenty four adult animals (males and females), mean aged 2.6 ±0.15 years, and the mean body weight 24.58 ±1.07 kg were used. The experimental animals were randomly divided into three equal groups. First group (Control group), transverse fracture was induced in the distal portion of radial bone and immobilized by Plaster of Paris, the fracture line didn't treated with any material. Second group (platelets rich fibrin group), the fracture line was surrounded by the platelets rich fibrin. Third group (bone marrow group), the fracture line was surrounded by autologous bone marrow. The radiographic results confirmed that the fracture healing was faster and superior in third group compared with first and second groups. The hematological results showed an increasing in concentration rates of alkaline phosphatase enzyme and calcium at the weeks that follows surgical operation. Depending on the serial rates of alkaline phosphatase, the third group and the second group are the better fractured bone healing than the first group. In conclusion, the results revealed that, the using of bone marrow and platelets rich fibrin improved and enhanced the healing of distal radial fracture.

The aim of this study was to evaluate the different methods of performing a Laparoscopic castration in dogs and to determine the efficiency and disadvantages of each of these methods. The study was conducted on 20 locally healthy dogs aged between 10-20 months and weights between 17-33 kg. The animals were randomly divided into four groups each group consisted of 5 dogs. In the first group, the castration was done by closed the ducts deferens with titanium clips, 4 clips were used, the average time for complete this surgery is (11.06± 1.19 Minute). The disadvantages of this method the possibility of failure to apply the clips. In the second group, laparoscopic castration was done by using Monopolar electrocautery, time requires for doing this operation is (34.85 ± 10.15 min.) the disadvantages of this technique bleeding may occur during cutting the spermatic cord, and the smoke of Monopolar electrocautery which impedes the vision of the surgeon. In the third group, extracorporeal ligation technique was used. This method proved highly efficient and prevented any bleeding because we did not need to cut the blood vessels, as well as the low material cost of this method compared to the other three groups. However, the time required to perform this procedure in this way was rather long compared to the remaining three groups where the time required to conduct the surgery is (36.82 ± 7.18) minutes and the disadvantages of this method is the tightening and twisting the blood vessels during pushing the knot to put her in the place as well as the length of the surgery time. While in the fourth group the laparoscopic castration was done by thermal cautery in which the clotting and cutting of blood vessels in the spermatic cord were done in the same tool, the time required to complete this surgery is (11.91±3.73 min). All the operations were performed under general anesthesia using Ketamine HCl 5% in dose 15mg/kg B.w and Xylazine 2% and 5 mg/kg B.W) as bolus i.m injection. Blood was collected from each animal before the surgery and 14, 30 days after the surgery to measure the level of testosterone hormone in the serum. The results showed there is no significant decrease before and after the surgery in the testosterone serum level. The testis was removed one month after the surgery to observe changes in testicular tissue and epididymis, there were hemorrhagic areas, necrotic regions, glomerulosclerosis and adhesions between the tunica vaginalis and the tunica albuginea. As well as the spermatozoa was stopped. Absences of the sperm in the epididymis (spermatogenia), also there are degenerative and necrotic changes in the epithelium of the epididymis and absence of the cavities of these nuclei in the sperm. We conclude from this study that laparoscopic castration in dogs can be performed in all methods which are mentions above, however, the thermal cautery method was the best method in terms of time, safety and economic cost.
