The relationship between gastric cancer, its precancerous lesions and bile reflux: A retrospective study
OBJECTIVE: To evaluate the relationship between gastric cancer (GC) and precancerous lesions and bile reflux. METHODS: Medical records of 30 465 participants who underwent gastroscopy between January and December 2018 in our center were reviewed. Their age, sex, time of endoscopy, endoscopic/histolo...

Sumario: | OBJECTIVE: To evaluate the relationship between gastric cancer (GC) and precancerous lesions and bile reflux. METHODS: Medical records of 30 465 participants who underwent gastroscopy between January and December 2018 in our center were reviewed. Their age, sex, time of endoscopy, endoscopic/histologic diagnosis and grade of bile reflux were recorded. The participants were further divided into the chronic gastritis group (n = 27 807), a precancerous lesion group (n = 1943) and a GC group (n = 715). The χ(2) tests and hierarchical analyses were performed. RESULTS: Patients aged 18‐27 years had a higher bile reflux rate than those aged 28‐37 and 68‐75 years (P < 0.001), while it did not differ between patients aged <50 years and those over 50 years (P = 0.639). It was lower in men than in women (P < 0.001). The bile reflux rate did not differ in terms of months, seasons and half of the year (all P > 0.05), but differed between morning and afternoon when they underwent the endoscopy (P = 0.000). There was an interrelationship between the severity of gastric mucosal disease and bile reflux grade (r = 0.171). After excluding the effects of sex, age and time of endoscopy on bile reflux, bile reflux rate in chronic gastritis and precancerous lesions was lower than in gastric cancer (P < 0.01). CONCLUSIONS: Bile reflux may be a risk factor for gastric cancer and precancerous lesions. A high grade of bile reflux may be associated with the progression of gastric mucosal diseases. |
