It is often difficult to manage such tumors located superior to the kidney by transperitoneal approach because of intraabdominal organs and IVC. We show the video of successful excision in two patients with a retrocaval tumor using the retroperitoneoscopic approach. METHODS Patient No.1 was a 43-year-old woman with repeated episodes of hypertensive attack and the high serum noradrenalin level. CT and MRI revealed a 35∼20∼35-mm tumor dorsal to the IVC at the level of the superior mesenteteric artery (SMA). The median border of the tumor extended beyond the SMA. MIBG scintigraphy was positive. Patient No. 2 was a 53-year-old woman with an incidentally found retrocaval tumor without any endocrinological abnormal findings. CT and MRI showed a 42∼30∼37-mm tumor dorsal to the IVC at the level of celiac arterial trunk. MIBG scintigraphy was negative. RESULTS In both patients, four trocars including a camera port were placed and the tumors were excised successfully without complications. Operating time was 168 minutes and 137 minutes, respectively. Postoperative course was uneventful in both patients. Pathologically, the tumor was paraganglioma in patient No.1 and schwannoma in patient No. 2. CONCLUSIONS The relatively large tumor located dorsal to the IVC can be successfully excised by the retroperitoneal endoscopic approach. By widely opening Gerata□fs (lateroconal) fascia and making a wide space superior and posterior to the kidney, a sufficient surgical view and space to operate the retrocaval tumor was obtained without being hindered by intra-abdominal organs. The retroperitoneoscopic surgical excision is feasible and safe for the management of retrocaval tumors. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e909 Peer Review Report Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Tomonori Habuchi More articles by this author Takamitsu Inoue More articles by this author Ryuichi Ito More articles by this author Yasushi Ichimura More articles by this author Naoko Kawata More articles by this author Norihiko Tsuchiya More articles by this author Masahiro Iinuma More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
