Summary

Predicting difficult colonoscopies is now possible by measuring cecal intubation time. Factors like older age, female gender, lower BMI, and specific patient histories indicate increased technical difficulty.

Area of Science:

  • Gastroenterology
  • Medical Diagnostics

Background:

  • Predicting technically difficult colonoscopies can optimize patient selection and scheduling.
  • Identifying predictive factors is challenging as cecal intubation is usually successful.
  • This study explored using cecal intubation time as an alternative measure for colonoscopy difficulty.

Purpose of the Study:

  • To identify patient characteristics that predict technical difficulty during colonoscopy.
  • To evaluate the feasibility of using cecal intubation time as a performance metric.

Main Methods:

  • Prospective recording of cecal intubation time in 805 consecutive outpatient colonoscopies.
  • Collected patient data included demographics, bowel habits, and medical history.
  • Analyzed 755 colonoscopies, excluding those stopped due to disease or poor preparation.

Main Results:

  • Older age and female gender were associated with longer cecal intubation times.
  • A body mass index (BMI) of 25.0 or less predicted difficulty in both genders.
  • Diverticular disease in women and a history of constipation or laxative use in men also predicted difficulty.

Conclusions:

  • Median cecal intubation time can effectively predict technical difficulty in colonoscopy.
  • Identified patient characteristics offer valuable insights for clinical practice and medical education.
