Description of intervention(s) / exposure
This study has a prospective and a retrospective component. This study is single center study, which will be conducted at the Gastroenterology department at the Princess Alexandra hospital. For the retrospective component, we will audit all patient records who have undergone Gastroscopy and Colonoscopy on the same day for investigation of positive FOBT from Jan 2010 until July 2019.
Gastroscopy which will take approximately 10 mins will be done on the same day as the colonoscopy (either immediately before or after the colonoscopy). There will be no additional anesthesia or observation required for the gastroscopy. Both colonoscopy and gastroscopy will be performed by a gastroenterologist. Patients will not be required to fill additional questionnaire or have phone interviews.
The retrospective part of the study will involve reviewing electronic medical records to collect information (demographic details including age, sex, BMI, ethnicity, medications, co-morbidities, outcomes of gastroscopy and colonoscopy, quality of bowel preparation, laboratory data (Full blood count, celiac serology, Iron studies and Helicobacter pylori status)) for patients who have undergone same day gastroscopy and colonoscopy.

Outcomes
Primary outcome [1] 327178 0
1. To assess the frequency of common gastrointestinal conditions (namely IDA and Celiac disease) and gastrointestinal symptoms in patients referred for evaluation of positive FOBT. This is a composite primary outcome and this will be assessed from endoscopy.
Timepoint [1] 327178 0
To be assessed on the day of the procedure
Secondary outcome [1] 394079 0
2. To determine the frequency of both upper and lower intestinal lesions in asymptomatic FOBT-positive patients and those with gastrointestinal symptoms.
This is a composite secondary outcome and will be assessed from the endoscopy.

Summary
Brief summary
This study will investigate the effect of same day dual endoscopy on finding common gastrointestinal conditions for patients referred for assessment of positive Fecal Occult Blood Test (Bowel cancer screening test)

Who is it for?
You may be eligible to join this study if you are aged 50 and above, and have been referred for investigation of positive Fecal Occult Blood Test (Bowel cancer screening test)

Study details:
All participants in this study will have two endoscopy procedures on the same day: an upper (gastroscopy) and lower (colonoscopy) as part of the routine clinical care for patients with a positive fecal occult blood test. We would also access your electronic medical records so we can confirm your diagnosis and test results. The findings from both upper and lower endoscopy will be used to evaluate occult GI bleeding.

Participants will not be asked to attend any additional appointments, outside their scheduled clinical visits. This study therefore has no effect and no foreseeable risk of harm to its participants. No attempts at directly contacting the patient or their family will be made. All the relevant findings from the endoscopy (both gastroscopy and colonoscopy) will be discussed with the participants by their gastroenterologist.

It is hoped these findings will provide further guidance/evidence to support the routine use of both upper and lower endoscopy for the evaluation of occult GI bleeding.
