[Computed tomography with continuous transport and continuous scanner rotation for laparoscopic cholecystectomy].
We investigated the 58 cases of cholecystolithiasis including 8 cases of choledocholithiasis treated with laparoscopic cholecystectomy. All patients received spiral CT scanning with drip infusion cholangiography (DIC-SCT), and 1.6 patients received endoscopic retrograde cholangiography (ERC), and the detection rates of the gallbladder, the bile duct and the cystic duct were compared. The gallbladder could be seen in 86.2% of cases with DIC-SCT and in 63.8% of cases with conventional DIC. The junction between the cystic duct and the common bile duct could be seen in 18 of 58 cases with DIC and in 49 of 58 cases with DIC-SCT. The DIC-SCT showed significantly superior anatomical details compared with images with conventional DIC. A comparison of DIC, ERC and DIC-SCT revealed that the junction between the cystic duct and the common bile duct could be identified in 14 of 16 cases undergoing ERC, in 13 of 16 cases receiving DIC-SCT and in 4 of 16 cases receiving DIC. Significant differences were noted among DIC-SCT, ERC and conventional DIC. We concluded that DIC-SCT is easy, non-invasive and useful for the preoperative assessment of laparoscopic cholecystectomy and also helpful for avoiding damage to the bile duct.
