Summary
The ileocecal valve is the most reliable landmark for confirming colonoscopic intubation of the cecum. Identifying this and other landmarks aids in accurate cecal visualization during procedures.
Area of Science:
- Gastroenterology
- Endoscopy
Background:
- Cecal intubation is crucial for complete colonoscopy.
- Identifying cecal landmarks can be challenging.
Purpose of the Study:
- To evaluate the reliability of three anatomic landmarks for confirming cecal intubation.
- To determine the most dependable landmark for cecal identification.
Main Methods:
- Reviewed 771 colonoscopic examinations confirmed to reach the cecum via fluoroscopy.
- Assessed the presence and combination of ileocecal valve, appendiceal orifice, and transillumination.
Main Results:
- 96% of patients had multiple cecal landmarks.
- The ileocecal valve was the most reliable landmark (98% visualization).
- Appendiceal orifice (87%) and transillumination (75%) were also assessed.
Conclusions:
- The ileocecal valve is the most consistently visualized and reliable landmark.
- Other landmarks are most valuable when identified with the ileocecal valve.
