Clinical Trial Data on Lidocaine Use in Unsedated Colonoscopy

A clinical trial involving 122 patients aged 18–40 years investigated the effect of perianal lidocaine application during unsedated colonoscopy. The dataset, published by Jiankun Wang on figshare, includes primary outcomes like anal and abdominal pain scores and secondary outcomes such as cecal intubation time and polyp detection rates. It was last updated in April 2026.

Use Cases

• Comparing patient-reported pain scores between treatment and control groups based on visual analogue scale (VAS) data.
• Analyzing the relationship between anesthetic use and procedural efficiency based on cecal intubation time.
• Investigating factors affecting polyp and adenoma detection rates in colonoscopy.
• Studying performance differences between junior and senior endoscopists based on the described outcomes.

Strengths

• Dataset is derived from a randomized controlled trial with 122 enrolled patients, providing a structured experimental design.
• Includes multiple measured outcomes such as pain scores, intubation time, and detection rates, allowing for multifaceted analysis.
• Released under the permissive CC-BY-4.0 license, facilitating reuse and sharing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 19.6 KB, indicating limited scope and likely a summary-level dataset.
