Background: Laparoscopic intracorporeal sutures and knots require advanced techniques in children. The JAiMY® needle holder (Endocontrol Company, Grenoble, France), a flexible jaw with both clockwise and anticlockwise revolving functions, enables the placement of sutures in very small working spaces. Using this tool, a novel new ligation method, which we named "twitching technique," can be performed. Methods: To perform the "twitching technique," first grasp the long tail of the thread with the JAiMY and the forceps on the needle side. Then, rotate the tip of the needle holder halfway in either direction and bring the forceps closer to the needle holder to make a ring using the thread. Grasp the thread at the crossing point with the forceps, and then catch the short tail through the ring with the needle holder. Results (Case Presentation): A 1-year-old boy presented with vomiting because of esophageal hiatal hernia. He was being treated for single ventricle and asplenia at our hospital. Laparoscopic esophageal hiatus plication was performed. Although the working space was extremely limited, the JAiMY and the "twitching technique" enabled steady suture placement and ligation. Conclusions: The "twitching technique" is an easy, steady, and safe method for performing ligation in difficult situations and may facilitate the performance of many laparoscopic surgeries in pediatric fields.
