Objective:
To describe the first series of robot-assisted laparoscopic radical prostatectomy (RALP) using the ALEXIS™ trocar device when removal of the specimen is necessary for intraoperative frozen-section pathology.
Materials And Methods:
Consecutive RALP using the ALEXIS were prospectively catalogue. Perioperative data, including preoperative oncologic diagnosis, operative time, estimated blood loss (EBL), size of incision for umbilical trocar, complications related to trocar, and length of hospital stay, were analyzed.
Results:
One hundred twenty-eight patients were analyzed. The mean operative time was 216 minutes, mean time to trocar placement was 4 minutes, and mean EBL was 172 mL. The incision size for a trocar was 2-3 cm in 117 patients and 1 incisional hernia was observed. The mean hospital stay was 3 days and mean follow-up was 4 months.
Conclusion:
The ALEXIS trocar provides an easy and fast intraoperative removal of the specimen for frozen pathology during RALP, even for large prostates. Safe and cosmetic results with a low intraoperative complication rate are acquired with the wound retractor.
