Background Knowing transient vascular perfusion abnormalities of testes after open inguinal herniotomy procedure is essential for the surgeon who is mainly responsible for the patient outcome. Purpose To assess the effect of open inguinal herniotomy procedure on the testicular blood supply in children using duplex ultrasonography (DUS). Material and Methods A prospective observational study included 60 boys (mean age = 9.46 ± 14.46 months; age range = 2 months–6 years) who underwent open inguinal herniotomy operation. Using DUS, the testicular volume, peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index (RI) were calculated preoperatively and one week, one month, and six months postoperatively. The pre- and postoperative measurements were compared. Statistical analysis was performed using χ2 test, Fisher’s exact test, or Student’s t-test when appropriate. Results On physical examination, the hernias were unilateral in 57 boys and bilateral in three boys. Comparison between testicular volumes preoperatively and postoperatively showed no significant change ( P > 0.05). There was a statistically significant increase of PSV and RI one week and one month postoperatively ( P < 0.0001) but returned to be near to the preoperative values at six months. As regards EDV, there was a slight but non-significant postoperative increase ( P > 0.05) which did not return to the preoperative value. Conclusion The affection of testicular vascularity postoperatively is transient and returns to be near to the preoperative values in the late postoperative period (six months postoperatively). Additionally, no significant change in testicular volume postoperatively.

Purpose:To assess vancomycin paste effect on poststernotomy healing in high-risk coronary artery bypass grafting (CABG) patients compared to bone wax using the 6-point computed tomography (CT) score. Additionally assessed the reliability of this score and its relationship to the occurrence of infection. Patients and Methods: A prospective comparative analysis included 126 high-risk CABG patients. The patients were randomly assigned into bone wax or vancomycin paste for sternal haemostasis. All patients were submitted to CT examinations 6-months postoperative. Two radiologists independently reviewed all CT scans to assess sternal healing using the 6-point CT score. The CT healing score of the two groups was compared. The kappa statistics were used to calculate the inter-reader agreement (IRA) of the 6-point CT score. Results: The final analysis included 61 patients in each group. The main CT score for sternal healing was 3.9±0.4 in the vancomycin group and 3.3±0.8 in the bone wax group. Patients in the vancomycin group had a higher statistically significant improvement in CT healing score than those in the bone wax group (p<0.001). There was no statistically significant relationship (p = 0.79) between the occurrence of infection and the 6-point CT score in the vancomycin group. The overall IRA of the 6-point CT score was good in two groups (κ = 0.79 in the vancomycin group and = 0.78 in the bone wax group). Conclusion: Vancomycin paste had a better CT healing score and can be used as a sternal haemostatic material instead of bone wax. The 6-point CT healing score is a reliable diagnostic tool for evaluating sternal healing.
