Studies on the robot-assisted single port laparoscopic surgery of gynecological malignant tumors / 解放军医学杂志

ABSTRACT

Objective To explore the technique of single port laparoscopy assisted by the third generation SI class Da Vinci robot in treatment of gynecological malignant tumors. Methods The clinical data were retrospectively analyzed of 8 patients with robot-assisted single port laparoscopy of gynecological malignant tumor from June to August 2018 in Changzheng Hospital. Of the 8 patients [aged 34–51 (43±6) years and BMI of 20.1–26.3 (23.2±3.1) kg/m2], 4 were early endometrial cancer and another 4 were early cervical cancer. With the help of porous instruments of ordinary robot system and Lagiport single-site multi-channel platform, the third generation SI class Da Vinci robotic surgical system was used to complete the robot assisted transumbilical single port laparoscopic surgery. Four patients with early endometrial cancer received total hysterectomy + double-adnexy resection + sentinel lymph node biopsy, and another 4 with early cervical cancer received radical resection of cervical carcinoma. Results Robot assisted single port laparoscopic surgery was successfully performed in all 8 patients with no additional auxiliary puncture port or laparotomy. The operation time was (208±68) min, and the intraoperative blood loss was (155±71) ml. No injury of ureter, bladder, rectum and obturator nerve and blood transfusion occurred during operation. No postoperative complications occurred such as blood transfusion, persistent fever, wound exudation, pelvic and abdominal infection and deep venous thrombosis. Four patients with endometrial cancer were discharged 4 days after operation, and another 4 with cervical cancer were discharged 7 days after operation. All patients were satisfied with the wound after operation. Conclusion The third generation SI-class Da Vinci robot can complete gynecological malignant tumor surgery with the help of ordinary robot instruments and Lagiport single-site multi-channel platform, which is one of the effective surgical methods for gynecological malignant tumor.
