Transumbilical Two-Port Laparoscopy With Percutaneous Needle Instrument: A Modified Technique for Pediatric Uncomplicated Appendicitis.

Background NeedAcute appendicitis is the most common pediatric surgical emergency. Conventional three-port laparoscopy is the mainstream surgical method currently. This study introduces a modified technique combining transumbilical two-port laparoscopy with miniature percutaneous needle-type forceps for pediatric appendectomy.Methodology and Device DescriptionThe modified procedure was performed through a transumbilical incision, employing laparoscopic needle-type forceps for pediatric appendectomy. The surgical technique utilized the following components: a 5-mm disposable laparoscopic trocar, needle-type grasping forceps, and 0- Mersilk Silk braided nonabsorbable suture.Preliminary ResultsA total of 30 pediatric patients were enrolled in this study, and all operations were completed by a single experienced surgeon. Relevant clinical indicators, intraoperative conditions and postoperative follow-up data were collected and analyzed. No intraoperative adverse events or postoperative complications were observed.Current StatusPreliminary clinical results demonstrate that this modified transumbilical two-port laparoscopic technique is technically feasible and clinically safe for children with uncomplicated acute non-perforated appendicitis. It achieves excellent cosmetic outcomes, reduces surgical trauma, and possesses prominent clinical advantages compared with traditional laparoscopic approaches.
