Luminal cross‐sectional area and tension–strain relation of the porcine bile duct

The bile duct is a distensible tube serving to transport bile from the liver and gallbladder to the duodenum. The purpose of this study was to characterize the luminal cross‐sectional area (CSA) and tension–strain properties during distension of the normal isolated porcine common bile duct in vitro....

Zusammenfassung:	The bile duct is a distensible tube serving to transport bile from the liver and gallbladder to the duodenum. The purpose of this study was to characterize the luminal cross‐sectional area (CSA) and tension–strain properties during distension of the normal isolated porcine common bile duct in vitro. An impedance planimetric system located inside a balloon was used. Eleven porcine bile ducts were examined in two locations, in the hepatic duct and in the common bile duct. The CSAs obtained in the common bile duct were significantly higher than those in the hepatic duct in the pressure range 0–8 kPa (P
