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 This study
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
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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a simplified robot (FASTER) helps doctors remove abnormal growths from the colon or rectum more quickly and safely than the standard method. About 40 adults aged 18 to 80 with such growths will be randomly assigned to one of the two procedures. The main goal is to see if the robot reduces total surgery time and lowers risks like bleeding or a hole in the bowel.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age between 18 and 80 years. 2. Patients with colorectal lesions scheduled to undergo endoscopic submucosal dissection (ESD) 3. Lesion characteristics meeting any of the following criteria: (1) Lesions unsuitable for en bloc resection using snare-based EMR, including non-granular type laterally spreading tumors (LST-NG), especially pseudo-depressed subtype (PD); lesions with type VI pit pattern (VI-type glandular opening configuration); carcinomas with superficial submucosal invasion (T1-SM); large depressed-type tumors; large protruding lesions suspected of malignancy, including nodular mixed-type granular LSTs (LST-G); other lesions unsuitable for en bloc resection using snare-based EMR; (2) Lesions with special background conditions, including mucosal tumors with submucosal fibrosis (caused by prior biopsy or mucosal prolapse due to peristalsis); sporadic tumors arising in the context of chronic inflammation (e.g., ulcerative colitis); local residual or recurrent early carcinoma following prior endoscopic resection; 4. Willingness to participate in the study and provision of written informed consent. Exclusion Criteria: 1. Suspected deep submucosal invasive carcinoma based on endoscopic features； 2. Lesions presenting with non-lifting signs, suggesting deep submucosal invasive carcinoma or tumors with severe submucosal fibrosis; 3. Lesions extending to the appendiceal orifice, colonic diverticulum, or ileocecal valve; (4) Pregnant women or women who may be pregnant; lactating women; 4. Pregnant women or women who may be pregnant; lactating women; 5. Patients with coagulation disorders; 6. Patients considered ineligible for specific reasons; 7. Patients with contraindications to anesthesia and/or colonoscopy. -
