Intraperitoneal effects of extraperitoneal laparoscopic radical prostatectomy

Area of Science:

• Urology
• Surgical Oncology
• Radiology

Background:

• Laparoscopic radical prostatectomy (LRP) is a standard treatment for prostate cancer.
• Comparing extraperitoneal (eLRP) and transperitoneal (tLRP) approaches is crucial for optimizing patient outcomes.
• Understanding postoperative findings is essential for accurate clinical interpretation.

Purpose of the Study:

• To compare routine radiologic and laboratory findings following eLRP and tLRP.
• To assess clinical correlations of these postoperative findings.
• To differentiate normal findings from potential complications.

Main Methods:

• Fifty patients undergoing eLRP or tLRP (laparoscopic and robot-assisted) were evaluated.
• Preoperative and postoperative laboratory tests (metabolic panel, CBC, amylase, lipase) were performed.
• Abdominal X-rays were conducted on a subset of patients postoperatively.

Main Results:

• All eLRP patients (100%) showed radiographic free air postoperatively, compared to 80% of tLRP patients.
• Few patients exhibited abnormal serum metabolic laboratory values.
• Length of hospital stay was significantly lower in the eLRP group (1.9 days vs. 2.2 days).
• Operative times and perioperative complications were similar between groups.

Conclusions:

• Extraperitoneal LRP and tLRP demonstrate comparable perioperative outcomes.
• Postoperative free air in eLRP patients is a common, normal finding and not indicative of bowel injury.
• Both surgical approaches are safe and effective, with potential benefits in reduced hospital stay for the eLRP approach.
