摘　　要：Portal vein cannulation is a rare complication of endo-scopic retrograde cholangiopancreatography(ERCP).It has been reported that it usually occurs after endo-scopic sphincterotomy,whereas in cases without prior sphincterotomy,the presence of portobiliary fistulas has been shown.Here,we present a case in which cannulation of the portal vein occurred despite careful wire-guided cannulation and the absence of sphinc-terotomy.Although fatal cases of cerebral and pulmo-nary air and/or bile embolism have been reported in patients with combined portal and hepatic vein trauma after ERCP and sphincterotomy,isolated portal vein cannulation,as in the current case,does not usu-ally result in mortality or serious morbidity.However,awareness of this rare complication is important so that no further intervention is performed.Portal vein cannulation is a rare complication of endo-scopic retrograde cholangiopancreatography（ERCP）.It has been reported that it usually occurs after endo-scopic sphincterotomy,whereas in cases without prior sphincterotomy,the presence of portobiliary fistulas has been shown.Here,we present a case in which cannulation of the portal vein occurred despite careful wire-guided cannulation and the absence of sphinc-terotomy.Although fatal cases of cerebral and pulmo-nary air and/or bile embolism have been reported in patients with combined portal and hepatic vein trauma after ERCP and sphincterotomy,isolated portal vein cannulation,as in the current case,does not usu-ally result in mortality or serious morbidity.However,awareness of this rare complication is important so that no further intervention is performed.
