Perfusion Assessment in Laparoscopic Left Anterior Resection

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).

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
