Same-Day Colectomy: is it Safe for Patients?

Inclusion Criteria:

* Access to a cell phone or computer and running water.
* Successfully completed pre-operative and post-operative education
* Medical criteria:
* Well controlled hypertension with systolic blood pressure \< 140 controlled by less than two medications which they are compliant with
* Well controlled diabetes on oral agents only with blood glucose level \< 180 on daily checks
* Anti-platelet agents including aspirin, clopidogrel, prasugrel, ticagrelor or ticlopidine will be stopped 7 days preoperatively and restarted on postoperative day 1. See exclusion criteria 7 for specific exclusion criteria regarding antiplatelet agents.
