Robot-assisted Laparoscopic Resection of a Large Paraganglioma: A Case Report

摘要

A 19-year-old female patient presented with headache, nausea, hypertension, visual impairment of the left eye and exertion-related complaints of palpitations since 1 year. Fundoscopy showed severe hypertensive retinopathy grade IV. A paraganglioma in the left para-aortic region was diagnosed by urinary screening and magnetic resonance imaging scanning. The tumor was resected by a robot-assisted laparoscopic procedure. The surgical operating time was 250 minutes and the blood loss was 150 mL. After surgery the blood pressure normalized and antihypertensive drugs were no longer required. Oral intake was resumed on the first postoperative day and the hospital stay was 3 days. Final pathology examination revealed a paraganglioma with pheochromocytomal features of 7x5.1x3.5 cm. Reports on laparoscopic resection of large paragangliomas are scarce. This case has demonstrated that the procedure is feasible and associated with rapid recovery from surgery. The surgical team experienced explicit support by the robot in the dissection of this highly vascularized tumor.
