The introduction of a second portal during endoscopic procedures is presented. This second portal allows passage of larger instruments while the surgical field is viewed with an endoscope placed through the first portal. This dual portal technique provides an angled view of the operative site, thus avoiding optical obstruction by tissue being pulled toward the endoscope. We report the use of this technique in 6 endoscopic cases.
