Abstract

BACKGROUND AND OBJECTIVES:

The purpose of this study was to evaluate the feasibility and validity of a dedicated da Vinci single-port platform in the porcine model in the performance of gynecologic surgery.

METHODS:

This pilot study was conducted in 4 female pigs. All pigs had a general anesthetic and were placed in the supine and flank position. A 2-cm umbilical incision was made, through which a robotic single-port device was placed and pneumoperitoneum obtained. A data set was collected for each procedure and included port placement time, docking time, operative time, blood loss, and complications. Operative times were compared between cases and procedures by use of the Student t test.

RESULTS:

A total of 28 surgical procedures (8 oophorectomies, 4 hysterectomies, 8 pelvic lymph node dissections, 4 aorto-caval nodal dissections, 2 bladder repairs, 1 uterine horn anastomosis, and 1 radical cystectomy) were performed. There was no statistically significant difference in operating times for symmetrical procedures among animals (P=0.3215).

CONCLUSIONS:

This animal study demonstrates that singleport robotic surgery using a dedicated single-site platform allows performing technically challenging procedures within acceptable operative times and without complications or insertion of additional trocars.
