Analysis of Intestinal Flora and Levels of Epidermal Growth Factor Receptor, Interleukin-32, and Gastrin 17 in Patients with Gastric Cancer via Carbon Nanoparticle Laparoscopy.

In order to explore the changes of intestinal flora and serum levels of relevant substances in patients with gastric cancer before and after surgery with carbon nanoparticle laparoscopy, a total of 180 patients with early distal gastric cancer who adopted laparoscopic radical gastrectomy for distal gastric cancer in the general surgery department of TCM Hospital of Shi Jia Zhuang City from January 2018 to January 2020 were selected and randomly divided into two groups: traditional laparoscopic operation (control group) and carbon nanoparticle laparoscopic operation (experimental group) were adopted for treatment for the two groups, respectively. Postoperative evaluation included the difference between the two groups in the operative time, the efficiency of intraoperative lymph node dissection, and the number of lymph node detection. The adverse reactions, changes of intestinal flora before and after surgery in the two groups, and the serum levels of epidermal growth factor receptor (EGFR), interleukin-32 (IL-32), and gastrin 17 were evaluated.
