Summary
This study explored a new thoracoscopic transdiaphragmatic approach for left adrenalectomy in pigs. The novel technique successfully removed adrenal glands, showing promise for future clinical applications.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Animal Models
Background:
- Current endoscopic adrenalectomy methods (laparoscopic, retroperitoneal) have limitations.
- These limitations include restricted access and limited working space.
- A novel approach is needed to overcome these challenges.
Purpose of the Study:
- To investigate the feasibility of a thoracoscopic transdiaphragmatic approach for left adrenalectomy.
- To assess the safety and efficacy of this technique in a swine model.
Main Methods:
- Five pigs underwent anesthesia, intubation, and ventilation.
- A left pneumothorax was created using CO2 insufflation and laparoscopic trocars.
- A posterior phrenotomy allowed access to the retroperitoneum for adrenal gland dissection and removal.
Main Results:
- Left adrenalectomy was successfully completed in all five pigs without intraoperative mortality.
- The transdiaphragmatic approach provided direct and rapid exposure of the left adrenal gland.
- Complications included splenic injury and difficulty with diaphragmatic suturing in one case each.
Conclusions:
- The thoracoscopic transdiaphragmatic approach is a feasible method for left adrenalectomy in a swine model.
- This technique offers direct access and efficient removal of the left adrenal gland.
- Further research is warranted to evaluate its clinical applicability in human patients.
