What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 tests a new surgery for early gastric cancer that uses two scopes (a laparoscope and an endoscope) to guide the removal of sentinel lymph nodes. The goal is to see if this approach is safe and effective. The study involves 36 people with early-stage stomach cancer.

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

Inclusion Criteria: * Preoperative assessment indicating that the tumor was confined to the mucosa or submucosa, consistent with the diagnosis of early gastric cancer. * Patients who required additional surgical intervention following initial endoscopic submucosal dissection (ESD) based on postoperative pathological evaluation. * Patients and their families fully understood the procedure, requested dual-endoscope assisted sentinel lymph node navigation surgery, agreed to participate in this clinical study, and signed the informed consent form. Exclusion Criteria: * Preoperative assessment indicating suspected lymph node or distant metastasis. * History of complex abdominal surgery rendering laparoscopic treatment infeasible. * Participation in another clinical trial within 4 weeks prior to enrollment or currently participating in another trial. * History of severe psychiatric disorders. * Pregnant or lactating women. * Uncontrolled infection prior to surgery. * Presence of other malignancies or comorbidities that may significantly affect survival. * Any other conditions deemed by the investigators as unsuitable for participation, or refusal by the patient or family to enroll. * Cardiopulmonary, hepatic, and renal functions were unsufficient to tolerate the surgery.
