Abstract:Objective To explore the short-term effect and serological examination results of laparoscopic assisted radical gastrectomy (LARG) and open radical gastrectomy (ORG) in treatment of patients with advanced gastric cancer (AGC).Methods The clinical data of 60 AGC patients who underwent radical gastrectomy from October2017 to October 2019 were retrospectively analyzed. They were divided into LARG group (n = 32) and ORG group (n = 28) according to different surgical methods. The levels of serum stress inflammatory factors and T cell subsets in both groups before and after surgery were detected. The occurrence of postoperative complications was compared between the two groups.Results The incision length, anal exhaust time, time of ambulation, extubation time of drainage tube and hospitalization time in LARG group were shorter than those in ORG group (P < 0.05), operation time was longer than that in ORG group (P < 0.05), and intraoperative blood loss was less than that in ORG group (P < 0.05). The postoperative utilization rate of analgesic drugs in LARG group was lower than that in ORG group (9.38% vs 32.14%) (P < 0.05), and scores of visual analogue scale (VAS) 1 d, 3 d and 7 d after surgery were lower than those in ORG group (P < 0.05). Levels of interleukin-6 (IL-6), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) in LARG group were lower than those in ORG group (P < 0.05) 3 d and 7 d after surgery, while levels of CD3+, CD4+, CD8+ and CD4+/CD8+ were higher than those in ORG group (P < 0.05). The incidence of complications in LARG group was lower than that in ORG group (3.12% vs 21.43%) (P < 0.05).Conclusion The curative effect of LARG is significant on AGC, which can reduce levels of serum stress inflammatory factors, with fewer effects on immune function and low incidence of postoperative complications.
