“…This was able to detect changes in testicular volume, which was equivalent to the use of laparoscopy in evaluating undescended testes reported by other authors [10,17]. Laparoscopy was not used during follow-up in this study because of lack of facilities and personnel required.…”

“…Injuries to the vas deferens and testicular vessels with resultant testicular infarction are common postoperative complications recorded especially in health facilities located in remote regions. The nonavailability of facilities and personnel required for laparoscopic and microsurgical orchidopexy [10][11][12] such as that which is obtained in developed countries compounded these problems.…”

“…Laparoscopic surgery is the primary surgical approach for the diagnosis and treatment of many surgical disorders, including intra-abdominal testes (cryptorchidism). 1 When compared with other approaches, the ''minimally invasive'' nature of laparoscopy is associated with reduced hospital length of stay as well as better cosmetic outcomes. 1 Pneumoperitoneum (PNP) induced by carbon dioxide (CO 2 ) insufflation allows for improved surgical visualization and maneuvering of laparoscopic instruments in the abdominal cavity.…”

Purpose The aim of this study was to describe the changes in respiratory system compliance and other measures of respiratory mechanics associated with peritoneal insufflation (12 mmHg pressure) with carbon dioxide (PNP12) and 20°Trendelenburg positioning (TDG20) in pediatric patients undergoing laparoscopic surgery for abdominal cryptorchidism.Methods Twelve subjects with abdominal cryptorchidism undergoing orchiopexy were enrolled in the study. General anesthesia was conducted with sevoflurane/O 2 /air, fentanyl, and rocuronium. Pressure-controlled ventilation with a peak inspiratory pressure (PIP) of 10-15 cm H 2 O and a positive end-expiratory pressure of 5 cm H 2 O was titrated to achieve a tidal volume (VT/kg) of 6-10 mLÁkg -1 and end-tidal carbon dioxide (EtCO 2 ) of 35-40 mmHg. Adjustments of PIP and respiratory rate (RR) were made to maintain the initial VT/kg and EtCO 2 \ 50 mmHg. Measurements of weight-corrected dynamic compliance (Cdyn/kg), VT/kg, and EtCO 2 were recorded at baseline, after PNP12, at TDG20, and again after deflation and return to the level position. Results Adjustments in PIP were required in all subjects to maintain the target VT/kg. The Cdyn/kg decreased 42% (95% confidence interval [CI]: 30 to 51; P \ 0.001) after PNP12, and it remained below baseline until deflation. The Author contributions Victor M.

The VT/kg decreased 42% (95% CI: 31 to 52; P = 0.048) with PNP12, and after TDG20, it decreased a further 10% (95% CI: 4 to 19; P = 0.038). After deflation, the VT/kg increased by 56% (95% CI: 28 to 90; P = 0.001) and was then adjusted back to the initial values. Conclusion The PNP12 significantly decreases Cdyn/kg and VT/kg in pediatric patients. The use of TDG20 produces a relatively minor additional impact in respiratory mechanics. This study emphasizes the need to adjust ventilator settings to maintain normal gas exchange during this procedure.
