Robot-assisted versus laparoscopic adrenalectomy: a systematic review and meta-analysis

Area of Science:

• Minimally Invasive Surgery
• Surgical Oncology
• Robotic Surgery

Background:

• Robot-assisted adrenalectomy (RA) is emerging as an alternative to laparoscopic adrenalectomy (LA).
• Existing studies suggest RA is feasible and safe, but comprehensive outcome comparisons are lacking.
• This meta-analysis evaluates early outcomes of RA versus LA.

Purpose of the Study:

• To compare the short- and long-term outcomes of robot-assisted adrenalectomy (RA) versus laparoscopic adrenalectomy (LA).
• To assess the advantages of RA over the laparoscopic approach in early surgical experiences.

Main Methods:

• Systematic search of PubMed, SCI/SSCI, CNKI, and Cochrane Library for studies published between January 2006 and December 2012.
• Included prospective randomized controlled trials and retrospective observational studies comparing RA and LA.
• Meta-analysis conducted following the Quality of Reporting of Meta-analyses (QUOROM) statement.

Main Results:

• Eight trials (232 RA cases, 297 LA controls) were included.
• RA patients had lower BMI and higher incidence of previous surgery.
• RA demonstrated significantly less blood loss and shorter hospital stays, while LA had shorter operating times. No significant differences in conversion rates or overall complications were found.

Conclusions:

• Robot-assisted adrenalectomy (RA) is a safe and feasible option in early experiences.
• RA is associated with reduced blood loss and shorter hospital stays compared to LA.
• Optimal patient selection and surgeon experience are crucial for RA success.
