This is a prospective cohort study of outcomes of patients undergoing outpatient colorectal surgery at a single institution to study outpatient colectomy as a viable treatment option for a select group of patients requiring colon and rectal surgery.

Inclusion Criteria:

• Ages 18-70
• Undergoing robotic-assisted right colectomy, sigmoidectomy, or low anterior resection.
• Able to perform greater than 4 metabolic equivalents (METS) without shortness of breath
• Must have a designated adult who can care for them at home postoperatively until their in-person clinic visit
• 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.

Exclusion Criteria:

• Medical criteria:
• Neurocognitive deficits not allowing for adequate preoperative education
• Congestive heart failure with EF < 45%
• Symptomatic aortic stenosis causing heart failure, syncope, dyspnea or angina
• Pulmonary fibrosis or pulmonary hypertension
• COPD or home oxygen use > 2L
• Chronic kidney disease of any stage.
• Lack of a caregiver at home or functionally bed-bound
• Ultralow pelvic resection
• Need for ostomy creation intraoperatively
• Operative time greater than 5 hours as this likely indicates a complex case and dissection necessitating closer monitoring in the hospital
• Conversion to open procedure intraoperatively
• Patients receiving antiplatelet agents such as clopidogrel, prasugrel, ticagrelor or ticlopidine within one year of coronary or carotid stent implantation, TAVR or LAAO placement.
• Patients on therapeutic anticoagulation medications such as warfarin, Eliquis, Xarelto, Enoxaparin
• Current tobacco use
• Patients who were unable to complete preoperative education, do not feel comfortable with care at home, or do not have an available caregiver for the first 7 postoperative days
• Any surgical history that would preclude safe abdominal entry for robotic surgery
