Objective: The aim of the study was to evaluate the prevalence and clinical aspects of Barrett's esophagus and adenocarcinoma of the lower part of esophagus in gastroscopy.
Material and methods: Retrospective review of 10000 upper gastrointestinal endoscopic examinations were performed at the Department of Oncology Endoscopy in Bydgoszcz from 2004 to 2014 in terms of incidence of Barrett's esophagus and adenocarcinoma in the lower part of esophagus.
Results: The medical records of 5378 (53.8%) women and 4622 (46.2%) men were analyzed. The average age of men and women was 62.4 and 62.7, respectively. Barrett's esophagus was diagnosed in 67 patients, including 38 (56.7%) of men where the average age of men and women was 56.9 and 60.2 years, respectively. The most commonly reported symptom was heartburn occurred in 45 (67.2%) of patients. During ten years of follow-up PB examination the adenocarcinomas were detected in 3 (4.47%) cases. Adenocarcinoma was diagnosed in 46 patients, of whom 37 in men. In the case of 27 patients (58.7%), esophageal cancer was treated with the intention of radicalization. The probability of 5-year survival in these patients was 10.2% for women and 9.2% for men.
Conclusions: The number of Barrett's esophagus and adenocarcinoma are increasing at 0.67% and 0.46% annually, respectively. The risk of adenocarcinoma developed from Barrett's esophagus during endoscopic follow-up period was 4.47%. Barrett's esophagus is more common in men before the age of 60, and nearly half of them have intestinal metaplasia without dysplasia. Probability of 5-year survival in patients with adenocarcinoma was 9.7%.
