The Battle Zone of Barrett’s Endoscopic Therapy: The Gastric Cardia

Long-term durability of complete eradication of intestinal metaplasia (CE-IM) is the goal of Barrett’s endoscopic therapy (BET), but it can be difficult to achieve, especially in the gastric cardia, where recurrences happen in up to 20% of patients. Several studies have reported on the presence of cardia intestinal metaplasia (IM) and dysplasia prior to and after successful endoscopic therapy in patients with Barrett’s esophagus.
This prospective study at a single tertiary center included 116 patients who underwent BET and achieved CE-IM. Of these patients, 17 (15%) were noted to have cardia IM/dysplasia (IM-12, LGD/indefinite-5). Among another cohort of 42 patients who were followed longitudinally, 12 (28%) had cardia IM/dysplasia pre-BET. At the 6-month follow-up, none of the patients had cardia IM and 3 (8.6%) had dysplasia, and at the 18-month follow-up, 2 (6.2%) patients had cardia IM and no patients had dysplasia. Cardia nodularity was associated with dysplasia both before and after BET. The majority of the nodular lesions were treated by EMR (69%), followed by radiofrequency ablation (98%).
