Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
We will be comparing two groups of outcomes in the same patient (ie. they become their own control group) - we will be practicing standard care with regards to endoscopic follow up of eradicated dysplastic Barrett's oesophagus and intramucosal oesophageal adenocarcima. This involves taking targeted biopsies of endoscopically abnormal areas (eg. nodules or ulcers) as well as biopsies from the gastric cardia and along the affected portion of the oesophagus in a systematic manner; four quadrant biopsies every 1cm will be taken as per the Seattle protocol, which is current standard of care. We will be recording the time and resources required for surveillance biopsies as well as the results of these to determine whether omitting these surveillance biopsies as per Seattle protocol in the future would be non-inferior to current standard of practice with regards to histology results and patient outcome; this would significantly save on time and costs associated with the process.

Therefore, the two groups will be as follows:
Control - gastric cardia, targeted and surveillance biopsies
Test - gastric cardia and surveillance biopsies only
Intervention code [1] 301791 0
Diagnosis / Prognosis
Comparator / control treatment
The patient would act as both a 'control' and 'interventional' group as the intervention we are implementing is theoretical.

Outcomes
Primary outcome [1] 306657 0
Proportion of abnormal biopsies (findings other than neo-squamous epithelium; ie. intestinal metaplasia) found on targeted and surveillance biopsies as per Seattle protocol during upper endoscopy in previously eradicated dysplastic Barrett's oesophagus
Timepoint [1] 306657 0
At time of upper endoscopy
Secondary outcome [1] 349164 0
Time involved with obtaining endoscopic surveillance biopsies as per Seattle protocol. This will be measured using stopwatch timers.
Timepoint [1] 349164 0
At time of upper endoscopy
Secondary outcome [2] 349165 0
Cost involved with obtaining endoscopic surveillance biopsies as per Seattle protocol. The Seattle protocol biopsies are placed in a new specimen pot for each centimetre. The costs for the histological assessment are clearly defined for a single pot of biopsies therefore allowing an exact cost calculation. The costs will be obtained from the Pathology Queensland website (http://hsqapps.hsq.health.qld.gov.au/testlistPQ/default.aspx), which have the cost of various investigations available.
Timepoint [2] 349165 0
At time of upper endoscopy

Statistical methods / analysis
We are aiming for 1000-2000 biopsies of neosquamous epithelium (taken from the site of previously eradicated Barrett's epithelium) as well as all additional targeted and cardia biopsies taken during these procedures. We will be comparing the two aforementioned groups with regards to time taken for procedure, costs, histological results and complications of procedure.
