Abstract:Objective To analyze the effect of 3D-CT describe the perigastric vascular and abdominal cavity variation of laparoscopic radical gastric cancer surgery.Methods The clinical data of 185 patients with gastric cancer treated in our hospital from January 2019 to January 2021 analyzed retrospectively. 3D-CT was used to describe the variation of gastric vascular and abdominal cavity. According to the condition of abdominal cavity, they were divided into observation group (common type of abdominal cavity, n = 159) and the control group (rare celiac trunk, n = 26), both groups were treated with laparoscopic radical gastrectomy. The perioperative indicators, inflammatory reactions and adverse reactions before and after the operation were compared between the two groups.Results The average blood loss, operation time and first exhaust time of the observation group were less than those of the control group; the serum IL-6, TNF-α, hs-CRP, NA, and ACTH levels of the observation group and the control group after the operation were higher than that before operation, but the observation group was less than that in the control group, the difference was statistically significant (P < 0.05).Conclusion Gastric cancer patients described by 3D-CT before laparoscopic surgery can reduce the amount of intraoperative blood loss to a certain extent, shorten the operation time, promote postoperative exhaust, relieve perioperative inflammatory reactions, and be better safty.
