Summary
This study compared transperitoneal and retroperitoneal laparoscopic access for adrenalectomy. Both approaches are safe and effective for adrenal lesions, with the retroperitoneal method showing a shorter operative time and faster oral intake.
Area of Science:
- Minimally Invasive Surgery
- Surgical Oncology
- Endocrinology
Background:
- Laparoscopic adrenalectomy is a standard treatment for adrenal lesions.
- Choosing between transperitoneal and retroperitoneal access can impact outcomes.
Purpose of the Study:
- To compare transperitoneal and retroperitoneal laparoscopic access for adrenalectomy.
- To evaluate operative time, blood loss, complications, and recovery between the two approaches.
Main Methods:
- A prospective protocol comparing 40 patients undergoing laparoscopic adrenalectomy.
- Twenty patients received transperitoneal access, and 20 received retroperitoneal access.
- Key outcomes analyzed included operative time, blood loss, complications, and recovery metrics.
Main Results:
- All procedures were successful; no conversions were needed.
- Retroperitoneal approach had significantly shorter operative times (2.5h vs 3.6h) and earlier oral intake (12h vs 24h).
- No significant differences were found in blood loss, analgesia, hospital stay, or return to normal activities. Complication rates were similar between groups.
Conclusions:
- Laparoscopic adrenalectomy is safe and effective for adrenal masses up to 10 cm.
- Both transperitoneal and retroperitoneal approaches offer comparable outcomes.
- The choice of approach depends on case specifics and surgeon preference.
