[Treatment of benign esophageal stenosis by prolonged dilatation: re-evaluation after 15 years].
The purpose of this paper is to re-appraise the results of a method for slow continuous dilatation of benign esophageal stenosis comparing previous experience of a decade with that accumulated during the following five-year period. A total of 78 patients were dilated, the average age was 58.1 years, and the M/F dilated, the average age was 58.1 years, and the M/F ratio 3.3/1. Reflux esophagitis was the most frequent etiology when comparing both groups (77.5% and 79.4% respectively). Esophageal hiatus hernia was the most common associated pathology in both groups (83.3% and 87.7% respectively). Gastric analysis showed average values within the limits of normal, 40% of de cases showed a hypersecretion pattern. The mean lower esophageal sphincter pressure was low, and a group of patients showed aperistalsis in more than 50% of the swallows, fact that was thought to be due to esophageal inability to clear the refluxed material. Another important fact was an increase in the frequency of Barrett's epithelium (6.5% to 9.3%). Undoubtedly the most important features were the increase in the number of good results of dilatation (87.7% to 92.3%), the decrease of morbidity (6.1% to 0.7%) and mortality (2% to 0.2%). The follow-up increased from X 27.3 to X 33.8 months.(ABSTRACT TRUNCATED AT 250 WORDS)
