Integration of robotics into two established programs of minimally invasive surgery for endometrial cancer appears to...

Area of Science:

• Minimally Invasive Gynecologic Oncology
• Surgical Technology Comparison
• Oncologic Surgical Staging

Background:

• Endometrial cancer staging often involves hysterectomy with lymphadenectomy.
• Laparoscopic and robotic-assisted approaches are utilized for surgical staging.
• Comparative outcomes between these minimally invasive techniques require evaluation.

Purpose of the Study:

• To compare perioperative outcomes and complications of laparoscopic versus robotic-assisted surgical staging for endometrial cancer.
• To assess complication rates, operative time, blood loss, and hospital stay between the two surgical methods.

Main Methods:

• Retrospective chart review of 432 patients undergoing total hysterectomy with pelvic and para-aortic lymphadenectomy.
• Comparison between robotic-assisted (n=187) and laparoscopic (n=245) surgical approaches over a four-year period.
• Analysis of intraoperative/postoperative complications, operative time, blood loss, lymph node yield, and hospital stay.

Main Results:

• Robotic surgery demonstrated a significantly lower rate of urinary tract injuries (0% vs. 2.9%, p=0.020).
• Robotic procedures resulted in shorter hospital stays (1.96 vs. 2.45 days, p=0.016) and less estimated blood loss (187 vs. 110 mL, p=0.0001).
• Laparoscopic surgery had a shorter operative time (161 vs. 218 minutes, p=0.0001) and a higher conversion rate (4.1% vs. 0.5%, p=0.027).

Conclusions:

• Robotic-assisted surgery is a viable alternative to laparoscopy for endometrial cancer staging.
• Robotic surgery may offer a reduced risk of urinary tract injury in selected patients.
• Both approaches showed comparable rates of overall intraoperative complications and lymph node retrieval.
