Objective: This study aims to investigate the application values of preoperative multislice spiral computed tomography angiography (MSCTA) in laparoscopic radical resection of gastric carcinoma (GC).
Materials and methods: A total of 108 GC patients were divided into Groups I (i.e., where preoperative MSCTA was performed; n = 60) and II (i.e., where preoperative MSCTA was not performed; n = 48). Surgery was performed by the same group of surgeons.
Results: Seven cases of blood vascular variation were detected in Group I during surgery, whereas four cases were detected in Group II. The operation time for Group I ([207 ± 24] min) was shorter than that for Group II ([260 ± 31] min) (95% confidence interval [95% CI]: -21.543--0.920, P = 0.044). The operation time of patients with gastric vascular anatomic variation in Group I ([189 ± 49] min) was shorter than that of patients in Group II ([257 ± 61] min) (95% CI: -99.68--3.201, P = 0.048). The differences in the number of lymph node dissection, average blood loss, eating time, complication rate, and postoperative hospital stay between the two groups was not statistically significant (P > 0.05).
Conclusions: MSCTA before endoscopic radical resection exhibits guiding values in assessing blood vascular variations and shortening operation times.
