To explore the clinical effect of three-dimensional reconstruction model in laparoscopic gastrectomy.

84 cases of gastric cancer with LAG from June 2018 to June 2019 treated in our hospital were divided into 3D group (n=42) and CT group (n=42) by adopting the method of random number table. The CT group used CT images for preoperative planning and intraoperative application. Adopting MICs 17.0 software to reconstruct three-dimensional celiac blood vessels according to CT data, the 3D group used three-dimensional models for preoperative planning and intraoperative application. SPSS18.0 software was used for statistical analysis. The measurement data, such as relevant indicators in perioperative period, were expressed as (±s) and analyzed by independent sample t test. The enumeration data such as postoperative complications were expressed as % and analyzed by χ² test. Indicating difference by P<0.05 was considered statistically significant.

Compared with the CT group, the 3D group can apparently shorten the operation time and average hospitalization time of laparoscopic gastrectomy, reducing the amount of intraoperative bleeding and intraoperative blood transfusion, and increasing the number of lymph nodes removed during the operation. The above differences are statistically significant (P<0.05). However, the differences between the two groups in first postoperative exhaust time and the incidence of postoperative complications are of no statistical significance (P>0.05).

Three dimensional reconstruction of celiac blood vessels applying to laparoscopic radical gastrectomy can accurately evaluate the classification and variation of patients' celiac blood vessels , which can provide important decision-making role during the operation. It has obvious advantages and is worthy of clinical promotion.
