What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study looked at 270 patients to see how accurate endoscopic ultrasound (EUS) is at diagnosing colorectal submucosal masses. Researchers compared the EUS results with the final pathology report. The goal is to improve how doctors identify these growths and guide treatment decisions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Endoscopic ultrasound (EUS) procedure
What this could lead to
If successful, this could help doctors more accurately diagnose colorectal masses without surgery, improving treatment decisions.
What could go wrong
This is a completed observational study, not a treatment trial. Results may not apply to all patients or settings, and EUS accuracy depends on operator skill and equipment.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study includes patients who were admitted to Shenzhen Hospital of Southern Medical University between 2015 and 2023 and underwent colorectal endoscopic ultrasound (EUS). Eligible participants are those diagnosed with colorectal submucosal tumors/subepithelial lesions based on the Chinese expert consensus on endoscopic diagnosis and treatment of gastrointestinal submucosal tumors (2023 edition) and related criteria. Patients whose EUS findings did not support a diagnosis of a submucosal tumor/subepithelial lesion were excluded.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Patients who were admitted to Shenzhen Hospital of Southern Medical University from 2015 to 2023 and underwent colorectal endoscopic ultrasound. * Patients diagnosed with colorectal submucosal tumors (subepithelial lesions) according to the Chinese expert consensus on the endoscopic diagnosis and treatment of gastrointestinal submucosal tumors (2023 edition). Exclusion Criteria: * Patients with endoscopic ultrasound diagnosis of non-submucosal tumors.
