Robotic transperitoneal infrarenal aortic lymphadenectomy: technique and results.

INTRODUCTION: This study was designed to evaluate the feasibility and the results of robotic transperitoneal infrarenal aortic lymphadenectomy. METHODS: Development of a technique of robotic transperitoneal infrarenal aortic lymphadenectomy in female cadavers and review of the results in 33 patients who underwent the newly developed technique as part of the surgical treatment of gynecologic malignancies. RESULTS: The mean console time was 42 minutes (range, 19-64 minutes). The mean number of nodes was 12.9 (range, 2-27); the mean number of positive nodes was 2.6 (range, 0-8). There was 1 conversion to laparotomy. CONCLUSIONS: Robotic transperitoneal infrarenal aortic lymphadenectomy can be performed adequately and safely with the robotic column at the patient's head. Operating table rotation and additional trocar sites are needed when used in conjunction with robotic pelvic surgery.

Robotic extraperitoneal aortic lymphadenectomy: Development of a technique.

OBJECTIVES: To develop a robotic technique for extraperitoneal aortic lymphadenectomy in cadavers followed by application in a patient with advanced cervical cancer. METHODS: Two fresh frozen female torso cadavers were used to develop the correct placement of the robotic column and trocars, respectively, to allow for a safe and adequate performance of aortic lymphadenectomy using the da Vinci S system. The resulting technique was applied to a patient with cervical cancer Stage IB2 presenting with enlarged aortic nodes. RESULTS: Appropriate sites for trocar and robotic column placement were identified in the female cadavers. In the patient, the operating, docking, and console times were 103, 3.5, and 49 minutes, respectively. The blood loss was 30 ml. Selective removal of 5 enlarged aortic nodes revealed no evidence of metastases. CONCLUSION: Robotic extraperitoneal aortic lymphadenectomy is feasible provided there is proper robotic trocar and column placement. The operating time and number of aortic nodes selectively removed by robotics in this patient are within the range of those reported with an extraperitoneal systematic aortic lymphadenectomy by laparoscopy.

Robotic radical hysterectomy: comparison with laparoscopy and laparotomy.

OBJECTIVE: Comparison of perioperative results of patients undergoing radical hysterectomy by robotics, laparoscopy, and laparotomy. STUDY DESIGN: Prospective analysis of 27 patients undergoing robotic radical hysterectomy between April 2003 and September 2006. Comparison was made with patients operated by laparoscopy and laparotomy matched by age, BMI, site and type of malignancy, FIGO staging, and type of radical hysterectomy. RESULTS: The mean operating times for patients undergoing robotic, laparoscopy and laparotomy radical hysterectomy were 189.6, 220.4, and 166.8 min, respectively; the mean blood loss was 133.1, 208.4, and 443.6 ml, respectively; the mean rate of blood loss was 0.7, 0.9, and 2.6 ml/min, respectively; the mean number of removed lymph nodes was 25.9, 25.9, and 27.7, respectively; and the mean length of hospital stay was 1.7, 2.4, and 3.6 days, respectively. There were no significant differences in intra- or postoperative complications among the three groups, no fistula formation in any patient and no conversions in the robotic or laparoscopic groups. At a mean follow up of 31.1 months, none of the patients with cervical cancer has experienced recurrence. CONCLUSION: Laparoscopy and robotics are preferable to laparotomy for patients requiring radical hysterectomy. Operating times for robotics and laparotomy were similar, and significantly shorter as compared to laparoscopy. Blood loss, rate of blood loss and length of hospital stay were similar for laparoscopy and robotics and significantly reduced as compared to laparotomy.
