[Robotic surgery in the management of early ovarian malignancy tumors].

OBJECTIVE
To apply robotic surgery of early ovarian malignancy tumors clinically and evaluate its feasibility in management for early ovarian cancer.


METHODS
Using the da Vinci robotic surgical system, seven patients with early ovarian malignancy tumors (stage I) underwent robotic surgery from April 2012 to September 2013. The average age was 45.7 years. Robotic surgeries approaches contained salpingo-oophorectomy, para-aortic lymphadenectomy, pelvic lymphadenectomy, omentectomy and appendectomy. Perioperative and follow-up clinical data were recorded.


RESULTS
All robotic surgeries were successfully completed without the conversion to laparotomy. The mean operative time was 225 minutes (100-330 minutes). The average estimated blood loss was 171 ml (20-600 ml). No patients received blood transfusions. No intraoperative and postoperative complications were observed. The average number of pelvic lymph node dissected were 18.3 (11-34). The average number of para-aortic lymph node dissected were 3.7 (3-4). The mean follow-up time was 26.0 months after surgery (20-36 months). Currently, all patients had no tumor recurrence and survived.


CONCLUSION
Robotic surgery is feasible as a novel alternative approach in the treatment of early ovarian malignancy tumors.
