Summary

This study is to evaluate the safety and efficacy of dual-endoscope assisted sentinel lymph node navigation surgery for early gastric cancer (EGC).

Conditions

  • Early Gastric Cancer

Interventions

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.
