Abstract:Objective To explore the application effect of linear cutting stapler in Roux-en-Y anastomosis assisted laparoscopic distal gastrectomy (LDG).Methods 126 patients underwent Roux-en-Y anastomosis after LDG were enrolled between March 2019 and March 2021. They were divided into observation group (n = 63) and control group (n = 63) by simple random grouping method. The observation group underwent Roux-en-Y anastomosis with linear cutting stapler, while control group underwent Roux-en-Y anastomosis with circular stapler. The operation time, intraoperative blood loss, number of lymph node dissection and positive lymph nodes, postoperative first exhaust time, the first time to eating fluid liquid food, extubation time of drainage tube and occurrence of postoperative complications in the two groups were compared. While 3 months after surgery, quality of life in both groups were followed up by short form 36 (SF-36) health survey questionnaire.Results The operative time, intraoperative blood loss, number of dissected lymph nodes and number of positive lymph nodes in observation group have no differences with those in control group (P > 0.05). The time of postoperative recovery of exhaust, first liquid feeding and drainage tube removal in observation group were significantly shorter than those in control group (P < 0.05). There was no significant difference in total hospitalization cost between the two groups (P > 0.05). The postoperative hospitalization time in observation group was significantly shorter than that in control group (P < 0.05), and incidence of postoperative complications was lower than that in control group (P < 0.05). After 3 months of postoperative follow-up, SF-36 scale in observation group was higher than that in control group (P < 0.05).Conclusion Compared to the circular stapler, the application of linear cutting stapler in Roux-en-Y anastomosis can effectively improve the safety of the operation and the postoperative safety, shorten the postoperative recovery time and improve the postoperative quality of life of patients.
