ABSTRACT
Objective:To investigate the efficacy of total laparoscopic radical gastrectomy for locally advanced esophagogastric junction carcinoma and its effect on patient's immune function and levels of tumor markers.Methods:A total of 106 patients who underwent total laparoscopic radical gastrectomy (total endoscopic group) in the Affiliated Cancer Hospital of Shanxi Medical University from January 2016 to April 2020 were collected, and 98 patients who underwent open radical gastrectomy (open group) in the same period were selected. The short-term efficacy, preoperative and postoperative immune function and tumor markers were compared between the two groups.Results:The operative time of the total endoscopic group was longer than that of the open group [(214±49) min vs. (165±32) min, t = 8.87, P < 0.01], the intraoperative blood loss was less than that of the open group [(86±50) ml vs. (113±53) ml, t = 3.59, P < 0.01], the postoperative first exhaust time was shorter than that of the open group [3.0 d (3.0 d, 4.0 d) vs. 3.5 d (3.0 d, 4.5 d), Z = 2.89, P < 0.01], and the incision length was shorter than that of the open group [(4.6±0.6) cm vs. (17.6±2.0) cm, t = 68.63, P < 0.01]. The postoperative proportion of CD4 + T cells, CD4 +/CD8 + and proportion of NK cells in the total endoscopic group were higher than those in the open group [(41±8)% vs.(36±8)%, t = 4.710, P < 0.01; 1.63 (1.19, 2.30) vs. 1.15 (0.87, 1.63), Z = 4.165, P < 0.01; 24.60 % (17.77 %, 32.50 %) vs. 19.25 % (13.35 %, 25.80 %), Z = 3.440, P < 0.01], while the postoperative proportions of CD8 + T cells and regulatory T cells in the total endoscopic group were lower than those in the open group [(26±11)% vs. (30±10)%, t = 2.375, P = 0.018; 3.37% (5.00%, 6.70%) vs. 4.48% (5.70%, 7.20%), Z = 3.057, P = 0.002]. Postoperative carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) in the total endoscopy were lower than those in the open group group [0.96 μg/L (0.54 μg/L, 1.50 μg/L) vs. 1.27 μg/L (0.70 μg/L, 2.98 μg/L), Z = 2.745, P = 0.036; 8.07 U/ml (5.48 U/ml, 13.07 U/ml) vs. 10.80 U/ml (6.54 U/ml, 19.93 U/ml), Z = 2.690, P = 0.043]. Conclusion:Compared with open surgery, total laparoscopic radical gastrectomy has less trauma and stress response, and has less impact on the gastrointestinal and immune function of patients, and the levels of tumor markers CEA and CA199 are low.
ABSTRACT
Objective To explore the operative approaches of gastric stromal tumor,and to evaluate the treatment effect of various operation methods. Methods The clinical and pathological data of 96 cases of gastric stromal tumor treated in People's Hospital of Shanxi Medical University from Jan 2011 to Jun 2015 were analyzed retrospectively. 16 cases got laparoscopic resection, 48 cases got gastroscope and laparoscopic combined resection, and 42 cases got open resection. Results For patients with tumor diameter 0.05). For patients with tumor diameter > 5 cm, the operation time, intraoperative blood loss, postoperative hospitalization days, postoperative complications, and postoperative metastasis of mortality in the laparoscopic group didn't have the advantage compared with the laparotomy group (P > 0.05). Conclusion Different diameter of gastric stromal tumor should adopt different surgical methods and ways, the indication is strict, otherwise easy to cause tumor residual or disseminated planting.
