Evaluación con manometría de alta resolución de una cohorte de pacientes con antecedentes de estenosis esofágica por la ingesta de cáusticos

Dysphagia after caustic ingestion may persist even after well-succeeded dilatation procedures and an open lumen suggesting other etiology for this symptom, such as dysmotility. Aims. This study aims to evaluate motility in a series of patients with previous esophageal stenosis after caustic ingestion at the light of high resolution manometry (HRM). Material and methods. Ten adult patients 5 women, mean age 54 (range: 28-83) years with previous esophageal caustic stenosis were recruited. The mean time from caustic ingestion to the esophageal test was 22 (range 6-45) months. All patients underwent successful endoscopic dilatation of the strictures and all of them were able to eat an unrestricted diet. Two (20%) patients complaint of mild dysphagia and 1 (10%) complaint of heartburn. All patients underwent a HRM. Results. Lower esophageal sphincter (LES) was defective in 8 (80%) patients with normal relaxation. Absence of peristalsis was present in 8 (80%) patients. Conclusion. Motility impairment was present in all patients with previous caustic ingestion that may explain dysphagia even when a mechanical obstruction is not detected by radiologic or endoscopic methods.
