Study summary

The purpose of this study is to investigate the attachment of a transparent hood ("cap") on the sigmoidoscope. The investigators hypothesis is that this will reduce pain, reduce investigation time, and increases the success rate of the sigmoidoscopy. The study focus on the less-experienced endoscopist.

Read the detailed description

The investigators randomize study subject to sigmoidoscopy +/- the attachment of the cap.

Using a 100mm VAS scale the investigators record pain when the sigmoidoscopy reaches its intubation end-point (60cm from anus). The investigators also register the time spent to this point and the rate of examinations not achieving this endpoint.

What researchers measure

Primary outcomes

  1. VAS recording of pain

    the registration is performed when the endoscopist has advanced the scope to the 60 cm mark.

    Time frame: During endoscopy. The subject is randomized immediately prior to the endoscopy. The outcome measures are all measured during examination.

Secondary outcomes

  1. Time

    Recording of the time it takes from the introduction of the endoscopy through anus until it reaches 60 cm intubation mark.

    Time frame: During endoscopy. The subject is randomized immediately prior to the endoscopy. The outcome measures are all measured during examination.

Other outcomes

  1. rate of success

    recording the rate of examinations that reached the intubation endpoint at 60cm from anus

    Time frame: During endoscopy. The subject is randomized immediately prior to the endoscopy. The outcome measures are all measured during examination.
