Trial Outcomes & Findings for Perfusion Assessment in Laparoscopic Left Anterior Resection (NCT NCT01560377)

NCT ID: NCT01560377

Last Updated: 2018-12-11

Results Overview

To demonstrate the utility of intra-operative assessment of colon perfusion, using the PINPOINT System to optimize the location at which to transect the colon in laparoscopic left colectomies and to assess mucosal perfusion of the completed anastomosis following proximal anastomosis in laparoscopic left colectomy.

Measure
Subjects Imaged With PINPOINT
Colonic tissue perfusion assessed with PINPOINT for laparoscopic left colectomy in the lower tract. PINPOINT Endoscopic Fluorescence Imaging System: The PINPOINT system will be used to provide real-time endoscopic visible and endoscopic NIR fluorescence imaging. PINPOINT enables surgeons to perform routine visible light endoscopic procedures as well as further visually assess vessels, blood flow and related tissue perfusion with near infra-red imaging during minimally invasive surgery
