Comparative Study of the Muyo Hook Technique and Conventional Methods for Primary Trocar Insertion in Laparoscopic Surgery

Background The Veress needle and open (Hasson) approach are common methods for creating pneumoperitoneum in laparoscopic surgery. However, these techniques can be time-consuming and carry the risk of organ or blood vessel injury. The Muyo Hook offers a new approach that allows direct trocar insertion without needing prior pneumoperitoneum. This study compares its effectiveness and evaluates perioperative outcomes with conventional methods in laparoscopic appendectomy and cholecystectomy. Materials and Methods A comparative study was conducted at Nur Hidayah Hospital from April to August with 40 patients divided into 3 groups: Group A (Muyo Hook, 16 patients), Group B (Veress needle, 14 patients), and Group C (Muyo Hook without Veress, 10 patients). The study measured the time from skin incision to Veress insertion (Groups A and B) and the time for the first trocar insertion. Safety outcomes were also assessed, including organ or vessel injury, hematomas, and pain. Results The Muyo Hook achieved pneumoperitoneum in an average of 18.05 seconds (range: 3.58-39.5 seconds), much faster than the conventional method (95.96 seconds; P < 0.05). Group C (Muyo Hook without Veress) had the quickest times. No complications were reported, such as organ or vessel injuries, skin hematomas, or pain. Conclusion Within the limitations of this study, the Muyo Hook technique appeared efficient, practical, and cost-effective. No complications were observed in this small cohort; however, larger prospective studies are required before drawing definitive conclusions regarding its safety. The device may simplify the procedure, reduce operative time, and enhance practicality for minimally invasive surgery.
