NCT06389448

Brief Summary

This is a prospective multicenter comparative study, aiming to compare probe-based confocal laser endomicroscopy (pCLE) and endoscopic biopsies in the diagnosis of the whole specific gastric lesion especially for distinguishing low grade intraepithelial neoplasia (LGIN) from high grade intraepithelial neoplasia (HGIN) and create an endoscopic image database for the follow-up research.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of pCLE and endoscopic biopsy in diagnosing the whole gastric lesion

    Using the pathological diagnostic result as the criteria, the accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) will be used to evaluate the diagnostic efficacy in diagnosing LGIN, HGIN and early gastric cancer.

    immediatly after the diagnostic result of biopsy, ESD and pCLE is available,or admission up to 2 months

Secondary Outcomes (1)

  • The histological upstaging rate of pCLE and endoscopic biopsy in diagnosing the whole gastric lesion

    immediatly after the diagnostic result of biopsy, ESD and pCLE is available,or admission up to 2 months

Study Arms (1)

pCLE-gastr

OTHER

pCLE will be used to acquire the images from the gastric tissue of the participants after preoperative fluorescein sodium allergy test (negative) and pre-ESD assessment,and before ESD resection.

Device: pCLE-gastr

Interventions

After identifying the location of the lesion through white light endoscopy, the pCLE operation is performed to acquire images from the specific gastric lesions, and finally the ESD routine is performed.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Over 18 years old and under 75 years old;
  • Patients with pathological diagnosis of LGIN, HGIN or early gastric cancer after conventional endoscopy biopsy, whose lesion has clear boundaries under endoscopic observation and is to be admitted for ESD surgery;
  • Patients who meet the indications for endoscopic resection of early gastric cancer, or LGIN patients who intend to undergo ESD surgery;
  • Patients who are able to provide pathological specimens/sections of previous endoscopic biopsy (in principle, it should be a case of this center).

You may not qualify if:

  • Patients with advanced gastric cancer or previous gastrectomy;
  • Patients with severe cardiopulmonary dysfunction, liver cirrhosis, renal dysfunction, acute gastrointestinal bleeding, esophageal-gastro varices, and coagulation disorders;
  • Patients who have a positive result in the fluorescein sodium allergy test;
  • Pregnant and lactating women;
  • Patients who have psychiatric disorders and are unable to cooperate with endoscopy or sign informed consent.
