Hyper-realistic rendering-assisted laparoscopic adrenalectomy for giant adrenal tumors: a pilot study

Area of Science:

• Surgical Oncology
• Medical Imaging
• Minimally Invasive Surgery

Background:

• Giant adrenal tumors pose surgical challenges due to their size and proximity to vital structures.
• Laparoscopic adrenalectomy is preferred for its minimally invasive benefits, but requires precise pre-operative planning for large tumors.

Purpose of the Study:

• To evaluate the clinical application value of hyperrealistic rendering (HRR) in laparoscopic resection of giant adrenal tumors.
• To assess the impact of HRR-based 3D reconstruction on surgical planning and outcomes.

Main Methods:

• Retrospective analysis of 25 patients with giant adrenal tumors undergoing laparoscopic resection.
• Preoperative enhanced computed tomography (CT) with hyperrealistic rendering (HRR) for 3D imaging and surgical planning.
• Analysis of operative time, blood loss, transfusion volume, and complications.

Main Results:

• HRR successfully determined tumor nature and guided surgical plans for all 25 patients.
• Preoperative HRR imaging accurately reflected the intraoperative anatomical landscape.
• All 25 surgeries were successful with no conversion to open procedures, minimal bleeding (median 200 mL), and no major vessel or organ injury.

Conclusions:

• Hyperrealistic rendering (HRR) provides valuable 3D visualization for complex laparoscopic adrenal tumor resections.
• HRR enhances understanding of tumor-organ relationships, potentially reducing operative risks and improving surgical success rates.
• This technology is beneficial for managing large retroperitoneal adrenal tumors laparoscopically.
