C-POEM as a therapeutic approach for cricopharyngeal achalasia.

A 66-year-old woman with a history of Sjögren's syndrome without visceral involvement, and low-grade non-Hodgkin lymphoma without mediastinal involvement, treated with rituximab in 2022 and in complete remission, was referred to Gastroenterology for progressive upper dysphagia of 10 years' duration. Dysphagia was initially limited to solids, but progressively worsened to involve both solids and liquids, requiring a soft or puréed diet. She also reported a 10% loss of body weight, with no heartburn, regurgitation, or other associated symptoms (Eckardt score 5).
