[Technique of intraoperative laparoscopic cholangiography]

Since laparoscopic cholecystectomy has been established at our institution, the routine use of intraoperative cholangiography was abandoned but preoperative intravenous cholangiography and sonography are mandatory. However, these investigations are not always conclusive and in some cases not applicable. We have therefore started to use selective intraoperative laparoscopic cholangiography for laparoscopic cholecystectomy. Our technique and the materials required for this peroperative investigation are described in the present article.
