HERNANDEZ-DE MEZERVILLE, Viviana et al. Achalasia, a 6 Years Study at the Calderon Guardia Hospital. Acta méd. costarric [online]. 2009, vol.51, n.2, pp.98-102. ISSN 0001-6002.

Objectives: To determine the general characteristics of patients with diagnosis of achalasia seen during the last 6 years at the Dr. Rafael Angel Calderon Guardia Hospital, their clinical presentation, diagnostic methods utilized, treatments given and the presence of disphagia within the following year after therapy. Methods: We analized the clinical records of patients with achalasia seen from january 2001 to january 2007. We also reviewed out patient clinic notes, looking for the persistence or recurrence of disphagia during the first year after therapy. Results: 30 patients were found and included in the study. There was a slight male gender predominance, and an average age of 50,37 years. All the patients had long standing dysphagia, the other most frequent symptoms were weight loss (43,33%) and chest pain (13,33%). The more commonly used diagnostic methods were esophageal manometry, endoscopy and barium esophagogram. Pneumatic dilation was the most frequently utilized treatment (46,67%) followed by surgery (26,67%). Half the patients recurred or continue having dysphagia during the year following treatment. The rate of complications was low and there were no esophageal perforations or mediastinitis. Conclusions: The general characteristics and clinical presentation of the patients agreed with those mentioned in the literature. Esophagic manometry was the most used diagnostic test and esophageal dilation was the preferred treatment. The rate of dysphagia within a year posttreatment was high.
