Background. The aim of this study is to show the utility of intraoperative cholangiography IOC in detecting unknown common bile duct calculosis during VLS cholecystectomy.
Methods. The General Surgery Unit of Carlo Poma Hospital in Mantova, carried out a retrospective study considering 288 VLS executed from January 1996 to May 1999. The study excluded the following categories of patients: those with an already known choledocholitiasis, those who underwent preoperative curative ERCP, and those with a preoperative cholangioRMN.
Results. The IOC has detected a hepatocholedochocalculosis in 31 patients (11.4% and in 7 cases there was a suspected calculosis. Twenty of the 31 patients did not present any element that could give the suspect of calculosis. In personal experience IOC showed in 11.4% an unknown hepatic choledochal calculosis after pre-operative echography routine examinations. The percentage of success of the intraoperative cholangiography was of 90%, the meantime for this procedure 15 minute.
Conclusions. The routinary execution of IOC during VLC is useful also considering its low costs.
