Abstract:
Objective:To explore the efficacy and safety of laparoscopic technology in the treatment of gastric cancer which using proximal subtotal gastrectomy and distal subtotal gastrectomy.Methods:A retrospective analysis was conducted on the clinical data of 98 gastric cancer patients admitted to the Department of General Surgery, General Hospital of Huainan Eastern Hospital Group from January 2016 to January 2020, including 71 males and 27 females with an average age of (62.03±10.6) years old(ranged from 32 to 80 years). All cases were divided into proximal group ( n=28) and distal group ( n=70) according to different surgical methods. The proximal group was treated with laparoscopic proximal subtotal gastrectomy, while the distal group was treated with laparoscopic distal subtotal gastrectomy. SPSS 20.0 software was used to analyze the differences in surgical related clinical indicators, postoperative complications, nutritional status, quality of life, and survival rate between two groups. Kaplan-Merier was used to draw survival curves, and Log-rank test was used to compare the survival differences between the two groups. Results:The number of lymph node dissection in the proximal group was less than that in the distal group, and the difference was statistically significant ( t=2.02, P=0.045). The incidence rate of reflux esophagitis in the proximal group was higher than that in the distal group (57.14% vs 4.29%, χ2=35.75, P<0.001), the incidence rate of reflux gastritis was lower than that of the distal group, the difference was statistically significant(3.57% vs 22.86% P=0.035). The levels of red blood cells, hemoglobin, and albumin in the proximal group were lower than those in the distal group after surgery, and the differences were statistically significant ( t=2.62, P=0.010; t=2.12, P=0.036; t=3.54, P=0.001). One month after surgery, the Karnofsky functional status score in the proximal group was lower than that in the distal group, and the difference was statistically significant ( t=2.27, P=0.025). The postoperative 1, 3, and 5-year survival rates of the proximal group were 85.71%, 64.29%, and 46.43%, respectively, while the postoperative 1, 3, and 5-year survival rates of the distal group were 88.57%, 71.43%, and 57.14%, respectively. There was no statistically significant difference in the survival curves between the two groups ( P>0.05). Conclusions:The incidence rate of reflux esophagitis after laparoscopic proximal subtotal gastrectomy is higher than that of distal subtotal gastrectomy, and the number of lymph nodes cleared during operation is less than that of distal subtotal gastrectomy. Compared with laparoscopic distal subtotal gastrectomy, the nutritional status of patients after proximal subtotal gastrectomy is significantly worse, but there is no significant difference in long-term survival rate between the two groups.
