Summary
Laparoscopic adrenalectomy offers reduced blood loss, shorter hospital stays, and improved patient comfort compared to open surgery. This minimally invasive approach is recommended for specific adrenal tumors.
Area of Science:
- Minimally Invasive Surgery
- Surgical Oncology
- Endocrine Surgery
Background:
- Limited comparative studies exist for laparoscopic transperitoneal lateral adrenalectomy versus open transretroperitoneal lateral adrenalectomy.
- Case-controlled studies are needed to evaluate surgical approaches for adrenalectomy.
Purpose of the Study:
- To compare outcomes of laparoscopic transperitoneal lateral adrenalectomy with open transretroperitoneal lateral adrenalectomy.
- To assess patient comfort, recovery, and morbidity between the two surgical techniques.
Main Methods:
- A case-controlled study involving 40 laparoscopic and 40 open adrenalectomies.
- Patients were matched for age, gender, endocrine disorder, tumor characteristics, and body surface area.
- Follow-up was completed in 92.5% of patients with a mean of 30 months.
Main Results:
- Laparoscopic adrenalectomy showed significantly less blood loss (40g vs 172g) and late morbidity (0% vs 47.5%).
- Operating time was longer (147 min vs 79 min) and analgesic use lower (2.9 vs 5.2) for laparoscopic procedures.
- Hospital stay (12 vs 18 days) was shorter with no significant differences in oral intake, ambulation, complications, or cost.
Conclusions:
- Laparoscopic adrenalectomy is a safe and effective technique offering enhanced patient comfort and reduced blood loss.
- The procedure leads to earlier hospital discharge without increased costs.
- Laparoscopic adrenalectomy is recommended for functioning adenomas and adrenal masses <6cm.
