%X background: surgeons and radiologists commonly believe that common bile duct dilates after cholecystectomy. aim: to measure common bile tract diameter before and 12 years after a cholecystectomy for cholelithiasis. material and methods: prospective study of 85 patients (aged 20 to 71 years, 68 fenmales) subjected to a cholecystectomy and followed for 12 years. ah were asymptomatic and had abdominal ultrasound to measure common bile duct diameter, seven days before and 12 years after the surgical procedure. results: common bile duct diameter before and 12 years after surgery was 4.6+0.9 and 5.0+1.8 cm respectively (p=ns) among 69 patients aged £¿ess than 60 years. the figures for 16 patients aged more than 60 years were 5+0.8 and 6.7+1.9 (p <0.03). conclusions: among patients below 60 years of age there is no significant change in bile duct diameter 12 years after surgery. in subjects over 60 years of age there is a significant increase in this diameter
