Laparoscopic Gastric Function Preserving Surgery Combined With Resection of the Anterior Lymphatic Drainage Area

7. februar 2023 opdateret af: Qinsheng Mao, Affiliated Hospital of Nantong University

Laparoscopic Gastric Function Preserving Surgery Combined With Resection of the Anterior Lymphatic Drainage Area. Comparison of Laparoscopic Standard Radical Gastric Cancer Surgery for Early Distal Gastric Cancer Multicenter, Prospective, Randomized, Open, Parallel-controlled, Non-inferiority Efficacy Clinical Trial

Nowadays, while pursuing the eradication of tumor, how to maximize the preservation of normal anatomy and physiological functions of the stomach, reduce the surgical trauma caused by excessive debridement, and improve the quality of life of patients after surgery has become a more important concern in the treatment of early gastric cancer. This prospective multicenter randomized controlled clinical trial was designed to elucidate the oncologic safety of laparoscopic gastric preservation surgery compared to standard laparoscopic gastrectomy. The oncologic safety of laparoscopic gastric preservation surgery with anterior basal dissection (SBD) compared to standard laparoscopic gastrectomy. This trial is an investigator-initiated, multicenter, prospective, randomized, open, parallel-controlled with a non-inferiority design. Patients diagnosed as distal gastric cancer with clinical stage T1N0M0, with a lesion diameter of 3 cm or less were eligible to participate in this study. Patients will be randomized to either laparoscopic stomach-preserving surgery with SBD or standard surgery. The primary end-point is 3-year disease-free survival.

Intervention / Behandling
EKSPERIMENTEL: gastric function preserving surgery combined with resection of the anterior lymphatic drainage area.
  1. Steps of sentinel lymph node dissection Indocyanine green (ICG) tracing of anterior lymph nodes. ICG injection: A 4mL volume of double tracer is injected into the submucosa of the four quadrants of the primary tumor by intraoperative gastroscopic method. 0.5 mL was injected at each site, and 15 minutes after gastroscopic tracer injection, the green anterior lymph nodes were carefully dissected and removed from the surgical area and evaluated for lymph node metastasis by parallel intraoperative freezing.
  2. Intraoperative and postoperative pathological examination Intraoperative histological examination of lymph nodes collected from the anterior lymph node pool was performed, If all collected anterior lymph nodes are negative, laparoscopic gastric function preserving surgery will be performed. After surgery, anterior lymph nodes that proved to be tumor-free on intraoperative frozen section examination were reevaluated.
Procedure: Laparoscopic gastric function preserving surgery combined with resection of the anterior lymphatic drainage area

ACTIVE_COMPARATOR: Patients in the control group will undergo standard laparoscopic gastrectomy
Patients in the control group will undergo standard laparoscopic gastrectomy (laparoscopic distal gastrectomy with simultaneous D1+ lymph node dissection).
