Objective: To report the first case series of robotic single-site (RSS) surgery via the da Vinci Si Surgical System for mature cyst teratoma cystectomy in China.
Materials and methods: The study was devised as a retrospective study in a single medical center. Five patients with mature cyst teratomas requested a minimally invasive surgical treatment. These patients were treated with RSS surgery for mature cyst teratoma between January 2014 and January 2015. RSS mature cyst teratoma cystectomies were performed with the da Vinci single-site platform in the Hainan branch of PLA General Hospital. Data regarding patient characteristics, surgical approach, and perioperative clinical outcomes were collected and analyzed in a retrospective study.
Results: All RSS procedures were completed successfully in the five patients. No instrument failure was noted during the procedures. The median operating time was 65 minutes (range 45–100 minutes). The median docking time was 20 minutes (range 18–28 minutes). No instrument failure was noted during any surgical procedures. The median blood loss was 30 mL (range 10–70 mL). No patient had massive intraoperative bleeding nor required a transfusion. No extra trocar was placed during the surgery. None of the patients had bladder or rectal injury. The median length of stay in hospital was 2.8 days. All patients were followed up until 6 months postoperatively, and no surgical complication occurred.
Conclusion: RSS mature cyst teratoma cystectomy using the wristed semirigid instrumentation is feasible. Randomized controlled trials with a larger number of patients and longer postoperative follow-up should be conducted to further evaluate the effect of this therapeutic strategy.
