RESUMEN
<p><b>OBJECTIVE</b>To introduce a new procedure of laparoscopic adrenal surgery.</p><p><b>METHODS</b>Thirty patients with adrenal disease underwent surgery by a 70 degrees lateral decubital trans-abdominal laparoscopic approach, which wa compared with 30 degrees decubital laparoscopic operation in 26 patients.</p><p><b>RESULTS</b>The procedure is superior to open laparotomy. There was significant difference in average operative time (77.2 min vs. 215.7 min), blood lost volume (27.0 ml vs. 94.5 ml), and postoperative complications (13.3% vs. 46.0%). Postoperative feeding time and hospitalization time were shortened markedly.</p><p><b>CONCLUSIONS</b>This modified technique is safe, straightforward, with a good anatomic view during operation. It could be widely adopted for the treatment of benign adrenal disease, especially pheochromocytoma.</p>
