• At time of surgery, has a completed anastomosis that is able to be visualized and is accessible to allow for circumferential sealant application with minimal bowel manipulation (≥90%)
• Completed anastomosis must be at a location where a WCE can be performed to evaluate for a sub-clinical leak
• Agree to return for all follow-up evaluations and procedures specified in the protocol
• Understand and give informed consent

Exclusion Criteria:

• Albumin < 3 g/dL
• ASA score (American Society of Anesthesiologists) ≥ 4

• Pregnant at time of surgery
• Has AIDS (HIV positive not excluded)
• Has neutropenia (IBD and steroid use not excluded)
• Has a known blood clotting disorder requiring treatment
• Has any condition known to effect wound healing, such as collagen vascular disease

• Has an emergent infection related to a previous colectomy procedure
• Is scheduled to undergo a Hartmann's procedure

• Is scheduled to undergo procedure using omental wrapping
• Is participating in another medical device trial involving colectomy with anastomosis
