Results

Patients with Barrett's esophagus have higher total bile acid concentration (total BA) and certain bile acid fraction concentrations (e.g. Conj CDCA).
The Spearman rank correlation coefficient between total BA and Conj CDCA is strongly correlated at 0.95.
Total BA, Conj CA, and Conj CDCA are strongly correlated with the color of gastric juice.
The color of the intragastric liquid was quantified to obtain a cutoff value (Youden Index) for the presence of Barrett's esophagus (YI 11.3).

Baseline Characteristics

The study subjects were patients who underwent gastroscopy at Yokohama City University Hospital from May 7, 2021 to September 31, 2021.

Participant flow

Gastroscopy was performed on patients who had refrained from eating and drinking for a certain period of time, and the esophagus, stomach, and duodenum were observed, intragastric fluid was collected, and biopsies were taken if necessary.

Adverse events

none

Outcome measures

background information (gender, age14,15, height, weight (BMI; Body Mass Index16), life history, preferences, H. pylori infection/elimination, previous history, surgical history, complications, and regular medications), last time they drank water, purpose of gastroscopy, Color of intragastric liquid and bile acid concentrations in stomach

Other

Other related information

Gastric fluid and clinical information obtained in the course of normal medical care should be collected.
Gastric fluid and endoscopic findings will be collected at the time of upper gastrointestinal endoscopy (including pathology results).
Based on the information obtained, the relationship between intragastric bile acid concentration and Barrett's esophagus and Gastro Esophageal Reflux Disease will be investigated.
