Preliminary results of five cases of laparoscopic adrenalectomy assisted by domestic robotic surgery system / 中华泌尿外科杂志

ABSTRACT

Objective:To investigate the safety and efficacy of domestic Kangduo robotic surgery system in adrenalectomy.Methods:This study summarized the clinical data of patients with adrenal adenoma who were operated by domestic kangduo robot from November 2020 to April 2021. This study was approved by the hospital ethics committee, and the clinical trials of medical devices were filed. Inclusion criteria age 18-75 years old; all of them in accordance with the indication of adrenalectomy; tumor volume≤6 cm; agree to sign the informed consent, follow the doctor's advice and follow up regularly. Exclusion criteria patients with ipsilateral upper abdominal surgery history; patients with severe uncontrolled disease or acute infection; patients with cardiovascular and cerebrovascular diseases, blood system diseases and immune system diseases that are not controlled and can not reach the operation standard; pregnant or lactating women. All patients underwent robot assisted adrenalectomy. The general information and perioperative data of the patients were summarized.Results:Five patients were included in this study, including 1 male and 4 female. The average age was 49 (34-61)years old. There were 2 cases on the left and 3 cases on the right. The average diameter of tumor was 2.2 (1.1-3.7) cm. All patients showed adenoma by CT examination. Two cases were diagnosed as primary aldosteronism, one as Cushing's syndrome, and two as nonfunctional adenoma. All the operations were successfully completed in 5 cases, including 4 cases via retroperitoneal approach and 1 case via peritoneal approach. The average docking time was 3.8 (3-6) min, the average operation time was 56.2 (21-92) min, and the average blood loss was 34 (20-50) ml. The postoperative pathology was adrenal cortical adenoma. The average postoperative hospital stay was 3.6 (3-5) days. No postoperative complications occurred in 5 cases. Two patients with primary aldosteronism had hypertension and hypokalemia before operation, and they needed oral antihypertensive drugs to control them. They did not need medication after operation, and their blood pressure and potassium were maintained at normal levels. All patients were followed up for average 1.5(0.5-5.0)months.Conclusions:Domestic robot assisted laparoscopic adrenalectomy has the advantages of few blood loss, short operation time, few complications. It’s a safe and effective operation, but the conclusion needs to be further verified by large sample and multi-center study.
