ABSTRACT
@#Objective To analyze the effect of microecological preparation on digestive tract complications and nutritional status after esophageal cancer surgery. Methods A total of 146 patients with esophageal cancer admitted to the Department of Thoracic Surgery, Renmin Hospital of Wuhan University from October 2017 to June 2019 were selected. There were 91 males and 55 females, aged 65 (61.9±8.2) years. They were randomly divided into two groups (an observation group and a control group, n=73 in each group) according to whether microecological preparation was given when they could take food one week after the surgery. Nutritional status and the incidence of gastrointestinal complications including anorexia, acid reflux, nausea, vomiting and diarrhea (≥3 times per day) in the first month after operation were compared between the two groups. Results The incidence of anorexia, nausea, diarrhea (≥3 times per day), anastomotic fistula and stenosis in the observation group was lower and the index of nutritional status was higher than those in the control group within one month after the operation (all P<0.05). There was no statistically significant difference in acid reflux, vomiting, lung infection and incision infection between the two groups (all P>0.05). Conclusion Microecological preparation can regulate gastrointestinal microecological balance, improve nutritional status, reduce the incidence of gastrointestinal complications and accelerate the postoperative rehabilitation.
ABSTRACT
@#The incidence and mortality of esophageal cancer are high, with strong invasiveness and poor prognosis. In China, the number of morbidity and death accounts for about half of the world. The cause of the disease has not yet been clarified, and it is known to be related to many factors such as chronic damage to the upper digestive tract caused by poor diet and lifestyle, heredity and environment. With the continuous advancement of molecular biology technology, metagenomics and high-throughput sequencing began to be used as non-culture methods instead of traditional culture methods for micro-ecological analysis, and is becoming a research hotspot. Many studies have shown that the disturbance of upper digestive tract microecology may be one of the causes of esophageal cancer, which affects the occurrence and development of esophageal cancer through complex interactions with the body and various mechanisms. This paper reviews the research progress, which is of great significance to further clarify the value of upper gastrointestinal microecology in the pathogenesis, diagnosis and treatment of esophageal cancer.
