The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry(HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type Ⅱ achalasia are better after treatment compared to younger patients, males and type Ⅲ achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies.展开更多

Several studies suggest that the response to the endoscopic treatment depends on several predictors. The aim of our study was to evaluate the endoscopic treatment of esophageal achalasia and identify the predictive factors of endoscopic treatment response. Patients and Methods: This is a retrospective analytical study of 78 patients with achalasia, managed in the gastroenterology department of the university medical center Hassan II-Fez, during a period of 5 years (January 2009 to December 2014). The diagnosis of achalasia was retained on a set of clinical, endoscopic, manometric and radiological arguments. A graded dilation protocol starting with a 35 mm balloon three times for 30 seconds in progressive pressure between 5 and 8 psi was performed. We used the Eckardt score to evaluate the clinical remission. Results: During the study period, 78 patients were included. The average age of our patients was 47 years old [18 - 81] with a sex-ratio M/F of 1.05. The average of Eckardt score before dilation was 5.9 [3 - 9]. An average of 1.41 dilation sessions was performed per patient with 85.9% of the initial success rate (n = 67). Initial success without further dilation sessions was achieved in 55.1% of our patients (n = 43). A clinical recurrence requiring further dilation sessions was observed in 30.8% of the cases (n = 24). The average relapse time after first dilation success was 2.7 years, 75% occurs within the first year. Dilation failure was retained in 14 patients (17.9%) requiring surgery. Only one post-dilation perforation was noted. In multivariate analysis, only odynophagia and the number of dilatation sessions were factors of failure of the endoscopic dilation. Conclusion: Pneumatic dilation is a minimally morbid and effective procedure. Our work showed that odynophagia, and the number of dilation sessions, are two predictive factors of endoscopic treatment failure.展开更多
