Four adjunct techniques can aid colonoscope insertion, with abdominal pressure and turning right being most effective. These methods were more frequently used in females and patients with intact colons.

Area of Science:

  • Gastroenterology
  • Endoscopy

Background:

  • Colonoscope insertion requires a basic technique to minimize looping and maintain scope alignment.
  • Four adjunct techniques exist to aid insertion, but their effectiveness is not well-established.

Purpose of the Study:

  • To prospectively evaluate the incidence and effectiveness of four adjunct techniques for colonoscope insertion.

Main Methods:

  • Data were collected from 417 patients undergoing colonoscopy by a single author.
  • The incidence and success rates of four maneuvers (hold breath, abdominal pressure, turn on left side, turn on right side) were recorded.

Main Results:

  • Colonoscopy completion rate was 97.1%.
  • Incidence and effectiveness varied: hold breath (63%, 32%), abdominal pressure (65%, 60%), turn left (36%, 42%), turn right (19%, 77%).

  • Abdominal pressure was most common; turning right was most effective. Techniques were used more in females, intact colons, and slimmer patients.

    • Conclusions:

    • Adjunct techniques can facilitate colonoscope insertion.
    • Turning the patient on the right side demonstrated the highest effectiveness.
    • Further evaluation of these maneuvers is warranted to optimize colonoscopy procedures.
