Abstract

Abstract: Aim of the Study: Because of the high prevalence of Barrett's esophagus (BE) and esophageal carcinoma, it is internationally recommended to perform routine endoscopies in adult esophageal atresia (EA) patients. This study aimed to evaluate the yield of follow-up after the first screening endoscopy. Methods: Prospective cohort study in a tertiary referral center since November 2011 was considered. All patients with EA ≥ 17 years old were invited to participate in the screenings and surveillance program. All patients underwent upper endoscopies with random biopsies of the distal esophagus at the level of the gastroesophageal junction and standard four-quadrant biopsies in case of BE. From the age of 25 years old chromoendoscopy with Lugol's staining was performed for detection of superficial squamous cell carcinoma. Depending on their age and the histologic results patients were recommended follow-up endoscopy every 3–5 years. Ethical approval had been obtained. Results: In February 2019, 190 patients (58% male, 83% type C, median age at time of first endoscopy 25.5) (range: 16.8–68.6 years) participated in the screenings and surveillance program. Forty-six patients underwent at least one follow-up endoscopy after median 4.7 (range: 1.0–5.9) years. Most recent surveillance endoscopy revealed a normal esophagus in 62%, esophagitis in 10%, and columnar-lined esophagus in 26% of the patients. Histology revealed inflammatory changes within normal limits in 49%, esophagitis in 22%, gastric metaplasia in 18%, and intestinal metaplasia without dysplasia in 6%. In 8 patients (6 males, median age: 25.9 (range: 22.5–34.4)) columnar-lined mucosa was a new finding at the second endoscopy, after median 5.0 (range: 3.6–5.9) years. In two of them histology revealed intestinal metaplasia without dysplasia. Conclusions: In line with previous studies, we found a 4-times increased prevalence (6.3%) of BE in adults with EA. Follow-up endoscopies detected two new cases of BE. Future studies are needed to identify patients at risk and personalize screening and surveillance regimes.
