[Partial cystectomy for bladder endometriosis: Robotic assisted laparoscopy versus standard laparoscopy]

Area of Science:

• Gynecologic surgery
• Minimally invasive surgery
• Endometriosis research

Background:

• Bladder endometriosis poses surgical challenges.
• Conventional laparoscopy (CL) is a standard treatment.
• Robot-assisted laparoscopy (RL) offers potential advantages in complex gynecologic procedures.

Purpose of the Study:

• To compare the efficacy and safety of robot-assisted laparoscopy (RL) versus conventional laparoscopy (CL) for surgical treatment of bladder endometriosis.
• To evaluate recurrence rates, complications, and clinical outcomes between the two surgical approaches.

Main Methods:

• Retrospective study (2007-2013) of patients undergoing partial cystectomy for bladder endometriosis.
• Comparison of 15 patients treated with RL and 22 patients treated with CL.
• Primary endpoint: radiological recurrence at bladder level; secondary endpoints included complications and clinical outcomes.

Main Results:

• No significant difference in recurrence rates (20% RL vs. 23% CL) or complications between RL and CL groups.
• Similar clinical improvement (93% RL vs. 86% CL) and pregnancy rates (93% RL vs. 86% CL).
• RL group had more associated endometriosis lesions (60% vs. 91% in CL, P=0.04) and larger bladder lesions (30±8mm vs. 23±7mm, P=0.03).

Conclusions:

• Robot-assisted laparoscopy (RL) is a safe and effective alternative to conventional laparoscopy (CL) for bladder endometriosis surgery.
• RL does not increase the risk of recurrence or complications compared to CL.
• Both techniques provide comparable long-term clinical benefits and pregnancy rates.
