Introduction: Paragangliomas are rare tumors of the autonomic nervous system. While they can occur anywhere along the sympathetic chain, the majority occur in the peritoneal cavity. Traditionally requiring laparotomy for removal, recent reports have emerged describing laparoscopic techniques for resection of these tumors. Here, we describe the technique of laparoscopic resection of two abominal paragangliomas aided by the use of intraoperative ultrasound.

Methods: Two patients with paragangliomas referred to our department in 2007 underwent laparoscopic resection. Both patients had tumor localization pre-operatively with contrast enhanced CT scans, and received adequate alpha blockade prior to surgery. Surgeon-performed intraoperative ultrasound was employed in both cases to aid in tumor localization.

Results: Both patients underwent successful laparscopic resection or their tumors. There were no intraoperative or postoperative complications, and both patients were discharged on post-operative day one.

Conclusion: Laparoscopic resection of abdominal paragangliomas is a safe and effective technique. The use of intraoperative ultrasound greatly facilitates the resection of these tumors by providing the relationship of the tumor to surrounding vascular structures in real-time.
