Incidence of use of PINPOINT System to aid in surgical colectomies decision making. [ Time Frame: Day of procedure - Day 1 ]
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.

Perfusion Assessment in Laparoscopic Left Anterior Resection
Open Label Clinical Study to Demonstrate the Utility of Intra-operative Perfusion Assessment Using NIR Fluorescence Angiography With the PINPOINT® Endoscopic Fluorescence Imaging System and to Assess the Impact of PINPOINT on the Surgical Decision Making Process and on Surgical Outcomes in Laparoscopic Left Anterior Resection Procedures
The purpose of this study is to demonstrate that NIR fluorescence angiography using the PINPOINT Endoscopic Fluorescence Imaging System ("PINPOINT System" or "PINPOINT") can assess viability of colon tissue during laparoscopic left colectomy. This information will provide the surgeon with clinically relevant information in assessing whether or not the tissue has adequate blood supply in the lower section of the colon prior to a colectomy.

Colectomy is a surgical procedure in which a part or all of the colon is removed. It is used to treat a variety of diseases including colon cancer, diverticulitis, inflammatory bowel disease (including ulcerative colitis or Crohn's disease) and infarcted bowel.

This study is the second phase of a three phase process to demonstrate the clinical utility of perfusion assessment by NIR fluorescence angiography in colectomy. The initial phase (Phase I) consisted of a number of small investigative studies that have now been completed. Upon successful completion of this study, it is anticipated that a prospective, multi center, randomized trial will be conducted (Phase III). Information learned from this present study will help guide the design of the randomized trial e.g. specific patient populations that may best benefit from this imaging modality and how randomization should be conducted (e.g. imaged cohort vs. non imaged, or all subjects imaged but then randomized to no image assessment in one arm of the study).

Phase 1
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
  • Rectal Cancer
  • Colon Cancer
  • Crohn's Disease
  • Polyp
  • Procidentia
  • Diverticulitis
Device: 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
Experimental: Subjects Imaged with PINPOINT
Colonic tissue perfusion assessed with PINPOINT for laparoscopic left colectomy in the lower tract.
Intervention: Device: PINPOINT Endoscopic Fluorescence Imaging System
