Ultrafine Endoscope for Colonoscopy in Diagnosis of Colorectal Diseases

June 9, 2014 updated by: Youlin Yang ,MD

Ultrafine Endoscope for Unsedated Colonoscopy is an Effective Method to Reduce Abdominal Pain:a Prospective Randomized Study.

This study is the evaluation of ultrafine endoscope (with small caliber and turning radius )for colonoscopy in decreasing abdominal pain of patients . 60 patients will be accepted in this trial.

Study Overview

Status

Unknown

Intervention / Treatment

Detailed Description

The aim of this study is to investigate the advantages of an endoscope with smaller turning radius and softer insert section in reducing patients' abdominal pain in colonoscopy. Transnasal gastroscope was selected in this study , because of its small caliber (5.9mm) and small turning radius . Visual analogue scale(VAS),cecum intubation time and cecum intubation rate were evaluated.

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ultrafine Endoscope
The ultrafine endoscope for colonoscopy with water method is performed in screening the colorectal diseases.
Ultrafine endoscope reaching to the cecum within 15mins is thought to be successful.Water colonoscopy with standard colonoscope will be performed in unsuccessful subjects subsequently.
Other Names:
  • Transnasal gastroscope
