Abstract

Background

Although the efficacy and safety of extensive endomucosal resection (EMR) in eradicating Barrett’s esophagus (BE) harbouring early neoplasia have been established, factors predicting efficacy remains unclear.

Aim

To determine the complete eradication rate of Barrett’s esophagus with high-grade intraepithelial neoplasia (HGIN) or intramucosal carcinoma (IMC), safety, and factors predicting complete eradication by EMR.

Methods

Patients with histological confirmation of Barrett’s HGIN/IMC were prospectively identified. EMR was performed using Duette multiband ligator or cap technique by a single operator (NEM).

Results

99 patients (81 males) with median age 67 years [interquartile range (IQR) 60–77 years] and median Barrett’s length 4 cm (IQR 2–6 cm) were included. Of 628 index EMRs [mean 6.3, median 5 (IQR 3–8)], 23% showed IMC, 58.5% showed HGIN, and 16% showed low-grade dysplasia only. A median of 8 EMR resections per patient (IQR 6–16, 1,064 resections in 89 patients) resulted in complete eradication of BE harboring neoplasia in 49.4% and eradication of HGIN/IMC in 81% (BE <5 cm subgroup: 65% complete eradication and 91% HGIN eradication) at median follow-up of 18 months (range 6–27 months). On univariate analysis, focal dysplasia (P = 0.003) and Barrett’s length <5 cm (P = 0.001) were predictors of complete BE eradication. Barrett’s length <5 cm was the only significant predictor [odds ratio (OR) 3.4, standard error (SE) 0.11, P = 0.0006] on multiple logistic regression analysis. Strictures developed in 27% and major bleeding in 2% with no procedure-related perforations or mortality.

Conclusions

Extensive EMR for removal of BE with early neoplasia is safe. Outcomes for complete BE eradication are modest at 49.4% and eradication of high-grade dysplasia at 81%. Barrett’s length <5 cm is the only significant predictor of complete response.
