Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
36

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

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.

Intervention / Treatment

Experimental: Sentinel Lymph Node Navigation Surgery
Laparoscopic-endoscopic cooperative surgery (LECS) Assisted Sentinel Lymph Node Navigation Surgery for Early Gastric Cancer
Procedure: Laparoscopic-endoscopic cooperative surgery (LECS) Assisted Sentinel Lymph Node Navigation Surgery
After preoperative assessment and confirmation of eligibility, patients received general anesthesia with endotracheal intubation. Indocyanine green (ICG) was injected submucosally around the lesion in four quadrants to trace the sentinel lymph node (SLN) basin. Laparoscopic marking of the SLN basin was performed. Endoscopy assisted laparoscopy in marking the primary lesion border (ensuring a margin of >0.5 cm). Laparoscopic sentinel lymph node dissection was performed, followed by endoscopic/laparoscopic full-thickness resection of the lesion. Gastric wall defects were closed laparoscopically. SLNs were harvested and sent for intraoperative frozen section pathology. If positive, a standard radical gastrectomy was performed; if negative, an abdominal drainage tube was placed to complete the procedure.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of perioperative complications.
Time Frame: One month after surgery
Postoperative complications comprised hemorrhage, obstruction, gastrointestinal motility disorders, and fistulas. The overall complication rate was calculated as the number of patients with complications divided by the total number of patients in the cohort.
One month after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of retrieved lymph nodes.
Time Frame: One week after the surgery.
The number of lymph nodes retrieved from all resected specimens.
One week after the surgery.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
R0 resection rate
Time Frame: One month after surgery.
The R0 resection rate was defined as the proportion of patients with histopathologically confirmed complete resection and negative margins among all enrolled patients.
One month after surgery.
Number of patients requiring further therapy
Time Frame: Three month after surgery.
Number of patients requiring further therapy (e.g., standard radical gastrectomy or chemotherapy).
Three month after surgery.
the number of postoperative hospital stay in days.
Time Frame: One month after the surgery.
Time from surgery to discharge was recorded in days.
One month after the surgery.
the number of time to first resumption of liquid diet in days
Time Frame: One month after surgery.
Time to first resumption of liquid diet was recorded in days.
One month after surgery.
the total number of Hospitalization costs in Chinese Yuan (CNY).
Time Frame: One month after surgery.
Total hospitalization costs were calculated in Chinese Yuan (CNY).
One month after surgery.
the rate of positive cytological examination results of peritoneal lavage fluid.
Time Frame: One week after surgery.
Cytological examination of the irrigation fluid from the surgical field was performed postoperatively. A finding of tumor cells was considered positive.
One week after surgery.
