Predictive Factors for Operative Time and Blood Loss in Retroperitoneal Laparoscopic Adrenalectomy: A Single-Center...

Area of Science:

• Minimally Invasive Surgery
• Surgical Oncology
• Urology

Background:

• Retroperitoneal laparoscopic adrenalectomy outcomes have improved over time.
• Factors influencing operative time and blood loss require clarification.
• The role of sealing devices in surgical efficiency is under investigation.

Purpose of the Study:

• Identify predictors of operative time and blood loss in retroperitoneal laparoscopic adrenalectomy.
• Clarify factors contributing to improved operative outcomes.
• Specifically evaluate the impact of sealing device use.

Main Methods:

• Retrospective review of 597 patients undergoing retroperitoneal laparoscopic adrenalectomy.
• Exclusion of robotic-assisted cases; analysis from December 1993 to October 2021.
• Logistic regression and propensity score matching to analyze predictors and device impact.

Main Results:

• Operative time and blood loss decreased over time, with recent improvements.
• Right-sided tumors, higher BMI, and no sealing device use predicted longer operative time.
• Male sex, higher BMI, and no sealing device use predicted increased blood loss; sealing devices showed significant benefits.

Conclusions:

• Appropriate use of sealing devices is independently linked to shorter operative time.
• Sealing devices are associated with reduced intraoperative blood loss.
• Sealing device utilization enhances surgical efficiency and safety in retroperitoneal laparoscopic adrenalectomy.
