Abstract:
Objective:To explore the preventive effect of probiotics on postoperative intesti-nal obstruction in patients after gastrointestinal cancer surgery and to analyze their impact on the diversity of the gut microbiota.Methods:A prospective study was conducted involving 133 pa-tients who underwent gastrointestinal cancer surgery at the Shanxi Cancer Hospital's Department of Hepatobiliary pancereatogastric surgery from January 2021 to January 2022.Patients were ran-domly divided into two groups,Group A and Group B,using a simple randomization method based on coin toss,with Group A consisting of 74 cases and Group B of 59 cases.Group A received rou-tine postoperative management along with oral probiotic formulations,while Group B received only routine management.The study compared gastrointestinal functional recovery indicators,observed the counts of major gut microbiota before and 7 days after surgery,the degree of microbiota dys-biosis,and intestinal barrier function indicators such as diamine oxidase(DAO),D-lactic acid,and histidine decarboxylase(HDC)between the two groups,and compared the incidence of complica-tions such as intestinal obstruction.Result:(1)The time to first flatus,first bowel movement,re-sumption of oral intake,and hospital stay in Group A were significantly shorter than in Group B(P＜0.05);(2)Seven days postoperatively,the counts of Enterococcus and Escherichia coli in Group A were significantly lower than in Group B,while the counts of Bifidobacterium and Lactobacillus were higher in Group A(P＜0.05);(3)The degree of microbiota dysbiosis 7 days postoperatively was statistically significantly different between the two groups(P＜0.05);(4)Seven days postoperatively,the levels of DAO,D-lactic acid,and HDC increased in both groups,with Group A having lower lev-els than Group B(P＜0.05);(5)The overall incidence of complications in Group A was significantly lower than in Group B(4.05％vs 15.25％,P＜0.05).Conclusion:Oral administration of probiotics after gastrointestinal cancer surgery can significantly improve the intestinal microecological environ-ment,regulate the counts of gut microbiota,promote the protective function of the gastrointestinal mucosal barrier,effectively reduce the incidence of complications such as intestinal obstruction,and has significant clinical application value.
