Abstract
To evaluate the usefulness of robot-assisted total laparoscopic hysterectomy with four equally-spaced ports (RA-TLH/4e) without an assistant port. In RA-TLH/4e, four da Vinci ports were placed horizontally at a height of 4 cm above the umbilicus with 8 cm equal spacing. Poor development of the surgical field or difficult forceps manipulations were handled with the endoscope and forceps movement (port-hopping). Patient background, surgical outcomes, complications, port-hopping frequency were compared in three groups: RA-TLH/4e, RA-TLH with four unequally-spaced ports (RA-TLH/4u), and conventional RA-TLH with five ports (RA-TLH/5). There were no significant differences in patient background or surgical outcomes among the three groups except for age, preparation time, and hospital stay, and no cases of laparotomy conversion or serious complications. RA-TLH/4e had fewer port-hoppings than RA-TLH/4u. The minimum abdominal width showed a weak negative correlation with port-hopping frequency in RA-TLH/4u, but not in RA-TLH/4e. RA-TLH/4e allowed for a reduction in personnel and costs compared to RA-TLH/5. The equal placement of four ports allowed sufficient port spacing even for patients with narrow abdominal widths. In addition, the port-hopping technique was able to fully compensate for the lack of an assistant port. RA-TLH/4e is a highly useful technique that not only excels in safety but also reduces costs.
