Comparison of Procedural Sequences in Same-day Painless Bidirectional Endoscopy With Colonoscopic Water Exchange Method

Dalin Tzu Chi General Hospital200 enrolled

Overview

This prospective randomized controlled trial is to compare evaluate the optimal procedure sequence among patients undergoing water exchange colonoscopy.

Same-day esophagogastroduodenoscopy (EGD) and colonoscopy (bidirectional endoscopy; BDE) are commonly performed to evaluate for gastrointestinal conditions, such as active gastrointestinal bleeding, iron deficiency anemia, positive fecal occult blood tests and abdominal pain. EGD-colonoscopy sequence seems to be the reasonable choice for BDE using air or CO2. With the use of water exchange method, endoscopists have to remove the dirty fecal material and air bubble during insertion. Gas insufflated during EGD may get into the colon and make subsequent water exchange colonoscopy more difficult. The aim of this prospective randomized controlled trial is to compare evaluate the optimal procedure sequence among patients undergoing water exchange colonoscopy.

Outcomes
