Jackhammer esophagus: Prevalence and demographic, clinical, and manometric characteristics

Abstract

Introduction and aims: Jackhammer esophagus is a recently identified motility disorder. Experience with the novel pathologic condition has been reported in different studies but there is little information on the subject in Latin America. Our case series conducted in Bogota, Colombia, describes the prevalence of jackhammer esophagus and its demographic, clinical, and manometric characteristics. Materials and methods: A retrospective, observational, cross-sectional study included consecutive patients diagnosed with jackhammer esophagus that were referred for high-resolution esophageal manometry. Their clinical and manometric records were reviewed, and the pertinent information for the present study was collected. Results: Within the study period, 6445 patients were evaluated through esophageal manometry, 27 of whom were diagnosed with jackhammer esophagus (prevalence of 0.42%). The majority of those patients were women (n = 17, 63%) in the sixth decade of life. The most common symptom was regurgitation (n = 17, 63%), followed by dysphagia (n = 15, 56%). The mean distal contractile integral was 9384 (5,095−18,546) mmHg·s·cm. Dysphagia was more common in patients > 60 years of age (79%, p 60 años y regurgitación más frecuente (92%, p < .03) en < 60 años. Conclusiones: Este es el primer estudio en caracterizar la prevalencia, hallazgos demográficos, clínicos y manométricos en pacientes con “Jackhammer Esophagus” en Latino América. En nuestra población, la prevalencia de este trastorno es notablemente más baja que en series internacionales. Nuestros hallazgos sugieren la existencia de importantes diferencias geográficas en la prevalencia y presentación clínica de “Jackhammer Esophagus” en comparación con datos de otros centros internacionales.
