목적: The aim of this study was to compare the short-term outcomes of robotic hysterectomy with the use of the new da V inci Xi^®and the da Vinci Si^® 방법: 40 patients underwent robot-assisted hysterectomy with the use of the new da Vinci Xi. The outcomes of Xi-Rob group were compared with a Si-Rob group selected using a case-matched methodology. 결과: There were no differences in outcomes between the two groups other than the mean weight of uterus (Xi-Rob: 243.93, Si-Rob: 216.94 grams, p=0.019). Xi-Rob was also associated with a shorter operation times((Xi-Rob: 100.2, Si-Rob: 142.58 minutes, p<0.001) and less consumption of analgesics. 결론: The new da Vinci Xi could offer some advantages with respect to the da Vinci Si in hysterectomy.
