Endoscopic Submucosal Injection of Indocyanine Green Before Laparoscopic Gastrectomy

Prospective Registry Study of Endoscopic Submucosal Injection of Indocyanine Green Before Laparoscopic Gastrectomy

Prospective registry study of endoscopic submucosal injection of indocyanine green before laparoscopic gastrectomy

To observe the imaging result of endoscopic submucosal injection of indocyanine green before laparoscopic gastrectomy, and analyze the relevant factors, so as to guide the operation of preoperative indocyanine green submucosal injection better.

This study is prospective and observational. In order to analyze the related factors that affect the imaging effect, we enrolled patients who were to undergo indocyanine green fluorescence imaging for laparoscopic radical gastrectomy.

Inclusion Criteria:

• patients who were to undergo indocyanine green fluorescence imaging for laparoscopic radical gastrectomy.

Exclusion Criteria:

• have simultaneously other cancer

  • have severe systemic inflammatory disease ,serious illness such as diabetes, chronic lung diseases
  • have upper gastrointestinal surgery
  • Indocyanine green or iodine allergy
  • the period is too late or the tumor is too large to carry on a laparoscopy assisted radical distal gastrectomy
