Single-Port Needlescopic Appendectomy in Children Using a Mediflex Needle: A New Simplified Technique.

Background: Laparoscopic appendectomy is among the most common surgical procedures. Needlescopic appendectomy (NA) is an acceptable, safe technique in children, but with many drawbacks such as a high conversion rate and long operative time. We present a new technique for NA in children using only a single port, Mediflex® facial closure needle, and vascular access cannula (VAC). Patients and Methods: Single-port NA was attempted in 117 patients (51 boys, 66 girls). Under general anesthesia, a 5-mm camera port was inserted through the umbilicus. Two Mediflex needles and a 14-gauge VAC were introduced. The appendix was grasped and dissected from the surrounding tissues using Mediflex needles. In case of a mobile cecum, the appendix was pulled through the umbilical port, then an extracorporeal appendectomy was performed. In cases with a fixed cecum or severely inflamed appendix, a complete intracorporeal appendectomy was done. The suture was knotted in a sliding reef knot using a single instrument. Results: NA was completed in 117 patients (51 boys, 66 girls) with an average age of 10 years. Thirty patients underwent extracorporeal appendectomy. Eighty seven patients were treated by intracorporeal appendectomy. The mean operative time was 15 ± 3 and 25 ± 4 minutes for extracorporeal and intracorporeal appendectomy respectively. The hospital stay was 1.2 days on average (ranging 8 hours to 2 days). There was no single case of conversion. Family satisfaction was achieved in 97% of cases. Conclusion: The presented unique method for single-port NA using Mediflex® appears to be a safe, acceptable technique for appendectomy in children that allows for excellent cosmetic results.
