AIMS: To evaluate the long-term outcome and quality of life (QoL) data, and to assess the potential influence of age and different conservative procedures on laparoscopic surgery. BACKGROUND: Current therapies for achalasia can palliate dysphagia, but other symptoms may persist, making it difficult to quantify and compare. To understand if they could influence results, we analyzed short- and long-term results and correlated them to age and previous conservative treatments using a specific QoL test. METHODS: Functional examinations (endoscopy, 24-hr pH manometry, upper GI X-rays) and the gastrointestinal quality of life index (GIQLI) were used before and after a laparoscopic Heller-Dor myotomy. Data were analyzed by the Mann-Whitney U test, Wilcoxon signed rank test, and Spearman's rho coefficient for bivariate correlations (p < 0.05). RESULTS: From January 1996 to January 2004, 31 consecutive patients out of 35 diagnosed with achalasia, in clinical stages I-III, were operated on by laparoscopy . Two groups were identified using the break point of 70 years of age, (20 younger and 15 older) and two subgroups according to the conservative therapy performed (20, none; 15, some). Patients underwent a clinical manometry evaluation at six and 12 months, and then yearly, and pH-metry at six, 24, and 60 months. In 78% of patients dysphagia disappeared and the incidence of reflux was 13%. Age and previous treatments did not influence surgical outcome. Patients completed a GIQLI questionnaire before surgery, six months after surgery, and then yearly (for five years). The median preoperative GIQLI score was 78 (range 38-109) out of a theoretical maximum score of 144. At a median follow-up of 49 months (range 24-72 months), the score had significantly improved to 115 (range 71-140). There was no significant statistical difference between the groups. CONCLUSIONS: Laparoscopic Heller-Dor myotomy is an effective palliation for achalasia; the long-term outcome is not significantly affected by preoperative conservative treatments or by the age of the patients. The GIQLI questionnaire is a reliable instrument to compare the impact of achalasia symptoms on health-related QoL before and after surgery.
