Complete colonoscopy is achievable in 95% of patients, even with obstructions. Experts can achieve 98% success rates excluding obstructions, with instrument type not impacting visualization.

Area of Science:

  • Gastroenterology
  • Endoscopy

Background:

  • Colonoscopy is a crucial diagnostic tool for colorectal diseases.
  • Success rates for complete colonoscopy vary, influenced by patient anatomy and lesions.

Purpose of the Study:

  • To evaluate the success rate of complete colonoscopy in an office setting.
  • To determine factors influencing the ability to reach the cecum during colonoscopy.
  • To assess the impact of colonoscope model and patient characteristics on colonoscopy completion.

Main Methods:

  • A retrospective analysis of 1,351 consecutive colonoscopies performed without fluoroscopy.
  • Utilized three Olympus colonoscope models: videoendoscope, CF-20L, and CFLB-3W.
  • Analyzed cecal intubation rates and factors affecting complete colonoscopy.

Main Results:

  • Cecal intubation was achieved in 95.9% of all procedures.
  • Complete colonoscopy success rate was 98% in cases without obstructing lesions.
  • Colonoscopy completion was more challenging in female patients, particularly those with prior hysterectomy, though instrument type showed no significant impact.

Conclusions:

  • Complete colonoscopy is highly achievable, with success rates approaching 98% in the absence of obstructive lesions.
  • Patient anatomy, particularly in women, may present challenges, but instrument choice is not a significant factor.
  • These findings support the efficacy of colonoscopy in an office setting for comprehensive colorectal examination.
