Structured Approach to Colonoscopy Technique Optimization: A Single-Center Experience with Novice Endoscopists
July 11th, 2025
This study presents an effective approach to performing colonoscopies. Achieving success in this procedure involves ensuring thorough bowel preparation, carefully inserting the scope while minimizing air insufflation, and skillfully managing any looping of the instrument.
My research focused on helping beginner learn endoscopy, specifically for early detection of gastrointestinal tumors. We use high-definition endoscope AI software to spot tumor and the VR simulators to help a beginner practice. Some challenges include improving early cancer detection, helping beginner learn faster and reducing the chances of missing tumors.
[Narrator] To begin rectum exploration, introduce the colonoscope into the rectum of a sedated patient. Minimize the use of air, and instead use water to reduce patient discomfort. Switch to air insufflation if bowel preparation is insufficient for water exchange or immersion. Using gentle motions, rotate the colonoscope while advancing through the rectum. For sigmoid colon exploration, adjust the tip of the colonoscope to slightly bend the lens for better navigation through the sigmoid colon. At the first turn at the junction between the rectum and sigmoid colon, rotate counterclockwise at a large angle, then proceed with a clockwise rotation along the rest of the segment. Ensure that the colonoscope rotates and moves freely without resistance. Identify and reduce any looping of the scope as needed. Next, explore the descending colon by rotating the colonoscope clockwise. Gently withdraw its body and slightly pull back through the descending colon. Keep the lens of the colonoscope steady to enhance visibility. Rotate counterclockwise as the scope transitions into the transverse colon. Now, advance the colonoscope by lifting the lens slightly while inhaling gently. Retract the scope carefully while pressing the lens down to maintain a stable position. As the hepatic flexure approaches, inhale and rotate clockwise to enter the ascending colon. Identify and resolve any looping of the scope. Inhale gently while continuing to advance the colonoscope through the ascending colon. Proceed until the ileocecal valve is out of view, then rotate the scope counterclockwise while keeping its tip elevated. Observe the ileocecal valve as a visual marker, confirming successful colonoscopy completion. Carefully inspect the ileocecal region and the appendix opening to ensure no lesions are overlooked. After the colonoscopy, monitor the patient closely for any abdominal symptoms, such as nausea, abdominal pain, or vomiting following the colonoscopy. More than 1,600 colonoscopies were performed over a course of a month, both with and without anesthesia. The average patient age was approximately 32 years, with the majority being women. A success rate of about 95% in reaching the ileocecal region was achieved. The average procedure time was nine minutes.
