There are two single port robotic systems, single-site or SP daVinci, available in gynecology. Here we submit the video that show the comparisons of two systems.
SP robotic system has an advantages to single-site robotics
1. Strong power identical to multiport
2. Various instruments developed
3. Applicable to various surgeries not only gynecology
But compared to single-site robotics, SP daVinci move slowly and take a time to learn third arm manipulation.
A 56-year-old woman came to our clinic because of bleeding. About 5.2cm sized endometrial mass lesion without definite deep myometrial invasion was found on pelvic MRI and endometrioid carcinoma was revealed on her endometrial biopsy. SP daVinci paraaortic lymphadenectomy as well as total hysterectomy and salpingooophorectomy was done.
Compare to single-site robotics, SP daVinci can use third arm to assist the operation. With SP daVinci system, paraaortic lymphadenectomy was safely done.
