Endoscopy and Colonoscopy Findings

This dataset provides detailed, structured information from gastrointestinal endoscopy and colonoscopy reports, including procedure details, sedation, findings, polyp and biopsy descriptions, pathology results, photodocumentation, and quality metrics. It is ideal for clinical research, quality assurance, and screening program evaluation in gastroenterology, supporting both patient care and population health analytics.

Behind this dataset

Same schema. As many rows as you need.

These 100 rows came out of a blueprint — 21 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with

Procedure ID and accession number unique
Procedure: EGD (upper endoscopy), colonoscopy, flexible sigmoidoscopy
Indication: screening, surveillance, symptoms, follow-up
Bowel prep quality for colonoscopy (excellent, good, fair, poor)
Cecal intubation achieved (yes/no) - quality metric
Withdrawal time documented (minimum 6 minutes)
Findings: polyps, diverticula, inflammation, masses, ulcers
Polyp size, location, morphology (pedunculated, sessile, flat)
