Radiological and orthopedic abnormalities in Satoyoshi syndrome

BACKGROUND: The advent of proton-pump inhibitors, and subsequently of the laparoscopic technique, can be assumed to have influenced the use of antireflux surgery in gastro-oesophageal reflux disease. METHODS: Data on antireflux operations carried out in Finland in 1988-93 were obtained from national statistics, and the number of operations performed laparoscopically in 1993 was ascertained by a questionnaire to all relevant units. The rates per 100,000 population in the catchment areas were calculated. RESULTS: Antireflux surgery almost always implied fundoplication. During 1993, 784 fundoplications and 43 other antireflux procedures were performed in Finland (total population around 5 million). The fundoplication rate per 100,000 population rose from 8.8 to 15.4 between 1988 and 1993. The increase was minimal (8.1-8.2) in 1990-91 when the first proton-pump inhibitor, omeprazole, was introduced, but remarkably greater (12.8-15.4) in 1992-93, when the laparoscopic technique became popular. Differences in fundoplication rates were six to tenfold between health service districts and even larger between hospitals. CONCLUSIONS: The numbers of antireflux operations in Finland were almost static when proton-pump inhibitors were introduced, but rapidly increased after the advent of the laparoscopic technique. Remarkable discrepancies were found in the incidence of fundoplication between different areas and hospitals.
