  Purpose
Water immersion insertion has been documented to decrease procedure-related discomfort during colonoscopy. Cap attached to the colonoscope tip may improve insertion and shorten cecal intubation time. The investigators would like to assess whether combination of cap-fitted colonoscopy and water immersion insertion is feasible and safe method of diagnostic colonoscopy. The primary endpoint is cecal intubation time and the investigators suppose that the use of cap is able to shorten it significantly. Patient comfort during colonoscope insertion, water consumption, length of the scope while reaching the cecum, need for external compression, need for positioning of the patient and endoscopist´s difficulty with colonoscopy are assessed.

Condition Intervention
Colonoscopy Device: soft straight distal cap D-201-14304 Olympus attached to the tip of the colonoscope Procedure: water immersion colonoscopy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Diagnostic

Primary Outcome Measures:
  • Cecal Intubation Time [ Time Frame: 3 months ]
    The primary endpoint (cecal intubation time) was defined as a time between introduction of the colonoscope into the anus and reaching the cecum.


Secondary Outcome Measures:
  • Patient Comfort During Insertion Phase of the Colonoscopy [ Time Frame: 3 months ]
  • Success Rate of Minimal Sedation Colonoscopy [ Time Frame: 3 months ]
    A successful minimal sedation colonoscopy was defined as reaching the cecum without switching to another insertion method and without additional sedation beyond the initial 2 mg of midazolam.


Enrollment: 208
