Laparoscopic resection of a retroperitoneal schwannoma.

Abstract

Although laparoscopic surgery for retroperitoneal diseases has been widely performed, there are few reports of laparoscopic resection for retroperitoneal tumors. We present the case of a 5-cm retroperitoneal tumor compressing the right common iliac vein and inferior vena cava that was successfully resected using a laparoscopic technique. Dissection between the tumor and the large vessels was performed safely using a harmonic scalpel and an ultrasonic surgical aspirator. Histopathology of the resected tumor showed a benign schwannoma. Laparoscopic surgical techniques should be considered for treatment of selected retroperitoneal tumors.
