A colonoscopy is a flexible scope that is inserted through the rectum to diagnose and treat problems with the lower GI tract (rectum, colon). It is commonly used to further work up patients with:
- Bright red blood per rectum (BRBPR)
- Melena
- Unexplained constipation/diarrhea
- Routine follow-up for patients with known polyps, IBD, other chronic bowel disease
- Colon cancer screening (in US, every 10 years after age 45)
Preoperative management
Patient evaluation
| System | Considerations |
|---|---|
| Neurologic | |
| Cardiovascular | |
| Pulmonary | |
| Gastrointestinal | |
| Hematologic | Anemia is common with lower GI bleed |
| Renal | |
| Endocrine | |
| Other | Most patients are "dry" from bowel prep and tolerate a fluid bolus well during the procedure. |
Labs and studies
- CBC w/ Hgb
Operating room setup
- Nasal cannula for oxygenation
- Have oral/nasal airway available
Patient preparation and premedication
- Bowel prep based on GI physicians
Regional and neuraxial techniques
- N/A
Intraoperative management
Monitoring and access
- Standard ASA monitors
- 1 PIV
Induction and airway management
- Small amount of propofol and lidocaine (for MAC)
Positioning
- Left lateral decubitus
Maintenance and surgical considerations
- Propofol drip (TIVA)
Emergence
- The Cecum is the turning point that determines the insertion and withdrawal phase of the colonoscope. When proceduralist states they have reached the cecum, the propofol drip can slowly be weaned down to time emergence.
Postoperative management
Disposition
- PACU and home unless unstable anemia
Pain management
- This procedure is well tolerated and requires minimal/no pain management.
Potential complications
- Colonic Perforation
- Post-polypectomy bleeding
