Introduction:
Retroperitoneoscopic adrenalectomy (RPA) has gained increasing popularity with its excellent perioperative outcomes and direct surgical access compared to other adrenalectomy approaches. We review perioperative outcomes of RPA by a specialized endocrine surgeon before and after expert intensive trainings (EITs), and to that of other laparoscopic adrenalectomy approaches at our center over a 9-year period, aiming to ascertain if RPA is worth the steep learning curve.
Material And Methods:
One hundred twenty one adrenalectomies were performed between January 2014 to June 2022. Patient demographic, tumor characteristics, and perioperative outcomes were retrospectively reviewed. The primary endpoints included procedure duration, complications, and length of stay. Part I of the study examined the effect of EITs on RPA's learning curve, and part II compared these outcomes with that of the alternative approach, transabdominal lateral adrenalectomy (TLA).
Results:
Both procedure duration and days in hospital markedly decreased after the two EITs for RPA. RPA resulted in a shorter procedure duration and hospital stay compared to TLA, and had lesser and milder intraoperative and postoperative complications compared to TLA.
Conclusions:
RPA results in safe and excellent outcomes, and offers additional benefit of direct surgical access, feasibility in patients with previous abdominal surgery, high body mass index, and multiple comorbidities. The steep learning curve can be overcome and shortened by EITs, motivating centers with specialized endocrine surgery to integrate RPA training into its curriculum, given its foreseeable rewarding outcomes.
