RESUMO
Background: Paraganglioma of the organ of Zuckerkandl (OZ) is a rare surgically challenging tumor because of its critical location and the nature of catecholamine secretion. We describe the technique of laparoscopic excision as well as provide a literature review to confirm its feasibility. Case Presentation: In a 23-year-old male patient, laparoscopic excision of a 5 × 4 cm tumor located at the aortic bifurcation and indenting the vertebral column was performed. Preoperatively, the patient received α- and ß-adrenergic blockers as well as underwent sperm banking. The patient was put in the lateral position, five ports were used: four in the midline and one in the left iliac fossa. The tumor was approached by the reflection of the colon. Ureter, gonadal vein, and sympathetic chain were preserved. Dissection of the tumor from the inferior mesenteric artery was done followed by control of three feeding arteries and two draining veins posteriorly and inferiorly. The procedure was completed laparoscopically with minimal blood loss. Intraoperatively, three episodes of hypertension developed and required stoppage and the administration of vasodilators. The patient recovered on the second day postoperatively and all antihypertensive medications were stopped. At 1 year of follow-up, the patient is tumor-free but developed anejaculation for which he is under current treatment. Conclusion: Laparoscopic excision of paraganglioma located at the OZ is safe and feasible.
