Aims: To assess the outcome of laparoscopic Heller-Dor myotomy for oesophageal achalasia in two groups of patients identified by age (under and over 70 years) using functional and clinical instruments.
Background: Current therapies for achalasia can't restore normal motility but can palliate dysphagia. Many other symptoms may persist difficult to quantify and to compare. In order to understand if age is a factor that influences the therapeutic outcome we tested the reliability of a specific QoL instrument for comparing outcomes of surgery for achalasia.
Methods: Functional examinations and the Gastrointestinal Quality of Life Index (GIQLI) were used before and after laparoscopic Heller-Dor myotomy.
Results: Starting in January 1996, 28 consecutive patients of 32 diagnosed (instrumental evidences) achalasia were operated on laparoscopically for various clinical stages of achalasia. In 78% of patients dysphagia disappeared, the incidence of gastro-oesophageal reflux was of 11%. The patients completed a GIQLI questionnaire preoperatively and after a minimum postoperative follow-up of 1 year. Median preoperative GIQLI score was 78(range 38-109) out of a theoretical maximum score of 144. At a median follow-up of 35 months (range 18-72), the score had significantly improved to 115 (range 71-140). All the items assessing gastrointestinal symptoms and physical, social, and emotional function were significantly improved. There is no difference between the two groups identified.
Conclusions: The laparoscopic Heller-Dor myotomy is an effective palliation for acalasia, the medium-term outcome is not affected by the age of the patients. The GIQLI is a reliable instrument to compare the impact of achalasia symptoms on health-related QoL.
