Reduced-port laparoscopic surgery
conventional laparoscopic surgery
locations of trocars: A 10mm trocar is placed in the supraumbilical or subumbilicus as an observation port, and the surgeon inserts a 10mm trocar and a 5mm trocar on the ipsilateral side of the patient according to the intraoperative situation, as the main operation port and the secondary operation port, and the positions of the trocars follow the principle that the lesion is located at the triangular apex of the two trocars.
locations of trocars: A 10mm trocar is placed in the supraumbilicus or subumbilicus as an observation port, and the surgeon inserts a 10mm trocar and a 5mm trocar in a suitable position according to the intraoperative situation as the main operation port and the secondary operation port. The assistant places two 5mm trocars in the appropriate position as the assistant operation port.
