Summary

Unsedated colonoscopy is feasible for willing patients, offering significant time savings for endoscopy units. Patient willingness to repeat the procedure remains unaffected, despite higher pain scores in the unsedated group.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Patient Care

Background:

  • Colonoscopy is a crucial diagnostic procedure.
  • Sedation is commonly used to improve patient comfort during colonoscopy.
  • The benefits and drawbacks of unsedated colonoscopy require further investigation.

Purpose of the Study:

  • To compare sedated versus unsedated colonoscopy.
  • To evaluate differences in procedure duration, patient pain, and willingness to repeat the procedure.
  • To assess the feasibility of unsedated colonoscopy in a clinical setting.

Main Methods:

  • A comparative study involving 403 patients undergoing colonoscopy.
  • Patients were offered either standard intravenous sedation or an unsedated procedure.
  • Data collected included anxiety levels, procedure time, discharge time, pain scores, satisfaction, and willingness to return.

Main Results:

  • Unsedated colonoscopy completion rates were comparable to sedated procedures (84.2% vs 85.9%).
  • Total discharge times were significantly shorter in the unsedated group (20.7 min vs 83.0 min).
  • Sedated patients reported lower pain scores (3.4 vs 5.7) and higher satisfaction (8.8 vs 7.8).
  • Willingness to repeat the procedure was similar between groups (77.3% vs 83.3%).

Conclusions:

  • Unsedated colonoscopy is a feasible option for patients willing to undergo the procedure.
  • This approach can save endoscopy units up to one hour per patient.
  • Unsedated colonoscopy does not negatively impact a patient's willingness to return for future procedures.
