Should Peritoneal Re-Approximation Be Performed After Transperitoneal Robot-Assisted Radical Prostatectomy?

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Transperitoneal robot-assisted radical prostatectomy (tRARP) is a common procedure for prostate cancer.
• The necessity of peritoneal re-approximation following tRARP remains a subject of clinical debate.
• Understanding the impact of peritoneal closure on patient recovery is crucial for optimizing surgical protocols.

Purpose of the Study:

• To evaluate the effect of peritoneal re-approximation versus non-approximation on the postoperative course after tRARP.
• To assess the relationship between peritoneal closure and key recovery metrics: drain removal time, analgesic requirements, flatus passage, and hospital length of stay.

Main Methods:

• A comparative study involving 247 patients undergoing tRARP by two experienced surgeons.
• Group 1 (n=108) underwent peritoneal re-approximation, while Group 2 (n=139) had no peritoneal closure.
• Preoperative parameters and postoperative outcomes were statistically analyzed and compared between the two groups.

Main Results:

• No significant differences were observed in preoperative characteristics (age, BMI, PSA) or pathological factors (comorbidity, Gleason score, stage, lymph node dissection) between the groups.
• There were no statistically significant differences in drain removal time, need for analgesics, time to flatus passage, or length of hospital stay between patients who had their peritoneum re-approximated and those who did not.
• Statistical analysis yielded P-values > .05 for all compared postoperative parameters, indicating no significant impact of peritoneal closure.

Conclusions:

• Peritoneal re-approximation following tRARP does not provide demonstrable postoperative benefits.
• The decision to re-approximate the peritoneum does not influence critical recovery indicators such as drain duration, pain management, or length of hospitalization.
• Based on these findings, routine re-approximation of the peritoneum after tRARP is not recommended.
