Guiding values of multislice spiral computed tomography angiography in laparoscopic D2 radical gastrectomy of local advanced gastric carcinoma.

Abstract

This study aims to investigate the application values of preoperative multislice spiral computed tomography angiography (MSCTA) in laparoscopic radical resection of gastric carcinoma (GC). 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. 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). MSCTA before endoscopic radical resection exhibits guiding values in assessing blood vascular variations and shortening operation times.
