Purpose: This study aimed to explore the application value of hyperrealistic rendering (HRR) in laparoscopic giant adrenal tumor resection.
Methods: We retrospectively analyzed 25 patients with giant adrenal tumors from January 2021 to January 2024, with a median age of 56 (40.5, 58.5) years and a tumor median diameter of 7.20 (6.80, 8.50) cm. All patients underwent preoperative medical HRR based on enhanced computed tomography, followed by laparoscopic adrenal tumor resection.
Results: HRR was used to initially determine the nature of the tumor and develop a detailed surgical plan, which was completed in 25 patients preoperatively. All 24 cases of tumors were located in the adrenal gland, 1 case was located in the retroperitoneum, and 13 and 12 cases were on the left and right side, respectively. Preoperative HRR 3D imaging was consistent with the intraoperative situation, and 25 cases had successful surgeries. The median operation time was 165 (120.0, 250.0) min, and median bleeding and blood transfusion volume were 200 (150.0, 450.0) and 200.0 (150.0, 450.0) mL, respectively. There were no collateral injuries to important organs and major vessels and no cases of conversion to open surgery.
Conclusion: For large retroperitoneal adrenal tumors, HRR for three-dimensional (3D) reconstruction imaging enables the operator to fully understand the relationship between the tumor and surrounding organs and blood vessels preoperatively, which can reduce intraoperative bleeding and collateral injuries, improve the success rate of laparoscopic resection, and safety of the operation.
