Assessment of Combined Bowel Preparation for Capsule Endoscopy Study

Mayo Clinic50 enrolled

Overview

The investigators are conducting a study to see if taking a bowel preparation before having a capsule endoscopy is more helpful than the standard preparation of not eating after 7 PM the night before a capsule endoscopy in making it easier to see the small bowel in order to find the source of gastrointestinal bleeding.

This is a single-blind, prospective randomized controlled study to determine if a combination of purgative agent, prokinetic agent, simethicone, and position will improve small bowel visualization, diagnostic yield, and completion rate of capsule endoscopy.

combination bowel preparation, which consists of: 1. drinking 2-liters (8 cups) of polyethylene glycol starting at 7 p.m. the night prior to the capsule endoscopy test; 2. drinking a teaspoon of simethicone 20 minutes prior to the capsule endoscopy test; 3. drinking a teaspoon of metoclopramide 20 minutes prior to the capsule endoscopy test; 4. lying on your right side for 30 minutes following the swallowing of the capsule endoscope.

Outcomes

Primary Outcomes

Improvement small bowel visualization, diagnostic yield, and complete rate of capsule endoscopy

The primary endpoints of small bowel visualization quality, diagnostic yield, and completion rate will be compared between groups using Pearson's chi-square test.

Time frame: 1 year

Secondary Outcomes

Safety outcomes and Patient satisfaction

secondary endpoints of safety outcomes and patient satisfaction with Pearson's chi-square test.

Time frame: 1 year

gastric transit time

A group comparison for the secondary outcome of gastric transit time will be done using a two-sample t-test or Wilcoxon rank-sum test, as appropriate.

Time frame: 1 year
