RESUMO
A Schatzki ring is a submucosal, fibrotic thickening located at the gastroesophageal junction. Endoscopic treatment traditionally involves disruption of the ring. Many approaches have been described including bougies, balloons, biopsies, and diathermic monopolar incision. While all of these approaches are effective in the short-term, recurrence is common. The objective of our study was to evaluate the feasibility of complete excision of the ring using jumbo cold biopsy forceps. Our main outcome measurements were the feasibility, safety, and efficacy of complete obliteration of Schatzki rings using jumbo cold biopsy forceps. We designed an observational study using a standard protocol for patient management and data collection using a university hospital as our setting. We followed 10 patients with dysphagia due to a Schatzki's ring, six of whom had previously undergone bougienage or balloon dilation. Five patients were on maintenance therapy with a proton pump inhibitor and one with an H2 blocker. Complete endoscopic obliteration of the Schatzki rings with a cold jumbo biopsy forceps was achieved in all 10 patients requiring a mean of 9.8 biopsies (range 8-12). Omeprazole (20 mg twice daily) was prescribed after the procedure. All 10 patients demonstrated improvement in dysphagia after treatment, which persisted during a mean follow-up time of 379 days (range 63-496 days). There were no serious complications. The limitations of our study include lack of a control group, a small sample size, and being a single-institution study. We concluded that complete Schatzki ring obliteration with jumbo cold biopsy forceps is a safe, feasible, and effective endoscopic treatment.
