To see the effect of choledochotomy and papillary bougienage on bile duct pressure, the pressure and the volume of drained bile during 7 postoperative days were compard between the bougienage group (n=9) and a group with cholecystectomy and biliary drainage via the cystic duct (n=9). Among 14 background factors, the caliber of the common bile duct was significantly different and subserved as a variable in the regression analysis of the biliary pressure and bile output. These two variable in each group underwent a second degree polynomial regression. The bougienage group showed higher daily slopes of the pressure with marginal significance and demonstrated the following regression equation: Pressure=-0.047 (Date-7.5)2+10.4 (cmBile). The slope of bile output was significantly increased in the bougienage group. Thus the postoperative pressure of the bile duct increased more in the bougienage group and culminated on the seventh day. The results suggested reconsideration on the biliary drainage after choledochotomy and papillary bougienage.
