Abstract:Objective To evaluate the clinical application effect and value of the modified new plane method combined with retroperitoneal approach 3D laparoscopic adrenalectomy in the precise surgical treatment of adrenal tumors.Methods 80 patients with adrenal tumors from October 2022 to December 2024 were selected as research samples. According to the random number table method, the patients were divided into the experimental group and the control group, with 40 cases in each group. The experimental group was treated with the modified new plane method combined with retroperitoneal approach 3D laparoscopic adrenalectomy, while the control group was treated with traditional retroperitoneal laparoscopic adrenalectomy. The surgical-related indicators, the incidence of intraoperative and postoperative complications, and the follow-up conditions of the two groups of patients were compared.Results The operation time, recognition time of the adrenal central vein, postoperative out-of-bed activity time, anal exhaust time, drainage tube removal time and hospital stay in the experimental group were significantly shorter than those in the control group, and the intraoperative blood loss was significantly less than that in the control group. The differences were statistically significant (P < 0.05). No blood transfusion or conversion to open surgery occurred during the operation in both groups of patients. There was no statistically significant difference in the total incidence of postoperative complications between the two groups (P > 0.05). The total incidence of intraoperative complications in the control group was significantly higher than that in the experimental group, and the difference was statistically significant (P < 0.05). All patients were followed up. There were no cases of loss to follow-up, and no local recurrence or distant metastasis occurred.Conclusion The modified new plane method combined with retroperitoneal approach 3D laparoscopic adrenalectomy is safe and effective in the treatment of adrenal tumors. It is worthy of clinical promotion and application.
