Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subjects Imaged with PINPOINT

Colonic tissue perfusion assessed with PINPOINT for laparoscopic left colectomy in the lower tract.

Group Type EXPERIMENTAL

PINPOINT Endoscopic Fluorescence Imaging System

Intervention Type DEVICE

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

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subject is scheduled for laparoscopic left colectomy in the lower region (planned anastomosis located 5 - 15 cm from anal verge)
* A negative pregnancy test for women of childbearing potential prior to surgery

Exclusion Criteria

* Subject has a previous history of adverse reaction or known allergy to ICG, iodine or iodine dyes
* Subject has any medical condition, which in the judgment of the Investigator and/or designee makes the subject a poor candidate for the investigational procedure
* Subject is a pregnant or lactating female
