Influence of cholecystectomy on bile duct width

The results of published prospective studies on changes in bile duct width after cholecystectomy are contradictory and comprise relatively few patients, often after short or medium‐term follow‐up. The objectives of this prospective long‐term follow‐up study were to investigate whether bile duct width increased significantly after cholecystectomy and to seek evidence of biliary obstruction in patients with excessively dilated ducts.
