Laparoscopic adrenalectomy: ascending the learning curve.

Area of Science:

• Minimally invasive surgery
• Surgical oncology
• Endocrine surgery

Background:

• Laparoscopic adrenalectomy (LA) is the preferred surgical method for most adrenal tumors.
• Assessing the learning curve and outcomes of the initial 100 LA cases is crucial for surgical training.

Purpose of the Study:

• To evaluate the outcomes of the first 100 laparoscopic adrenalectomies performed by a single surgical team.
• To analyze the learning curve associated with laparoscopic adrenalectomy.

Main Methods:

• Retrospective analysis of prospectively collected data from 100 consecutive laparoscopic adrenalectomies.
• Key parameters included surgical indications, operative details, complications, tumor characteristics, conversion rates, and length of stay.
• The learning curve was assessed by dividing cases into three equal groups.

Main Results:

• The study included 100 LAs in 90 patients for various conditions like pheochromocytoma, Cushing's syndrome, and Conn's syndrome.
• Major morbidity was 9% with one mortality; 5% of cases required conversion to open surgery.
• Significant reductions in intraoperative complications and operating time were observed as the surgical team gained experience (p < 0.05).

Conclusions:

• Laparoscopic adrenalectomy outcomes are closely linked to a surgeon's learning curve.
• Proficiency in laparoscopic adrenalectomy appears to be achieved after approximately 30 cases for an experienced surgeon.
