[Computed tomography with continuous transport and continuous scanner rotation for laparoscopic cholecystectomy]

Area of Science:

• Gastroenterology
• Surgical Imaging
• Diagnostic Radiology

Background:

• Cholelithiasis and choledocholithiasis are common conditions requiring surgical intervention.
• Laparoscopic cholecystectomy is a standard treatment, necessitating precise anatomical visualization.
• Accurate preoperative assessment of the biliary tree is crucial for surgical success and safety.

Purpose of the Study:

• To compare the diagnostic efficacy of DIC-SCT with conventional DIC and ERC.
• To evaluate the detection rates of gallbladder, bile duct, and cystic duct anatomy.
• To determine the utility of DIC-SCT in preoperative planning for laparoscopic cholecystectomy.

Main Methods:

• Retrospective analysis of 58 patients undergoing laparoscopic cholecystectomy.
• Comparison of imaging data from DIC-SCT, conventional DIC, and ERC.
• Assessment of visualization rates for gallbladder, common bile duct, and cystic duct junction.

Main Results:

• DIC-SCT visualized the gallbladder in 86.2% of cases, significantly higher than conventional DIC (63.8%).
• The cystic duct-common bile duct junction was identified in 49/58 cases with DIC-SCT versus 18/58 with conventional DIC.
• DIC-SCT demonstrated superior anatomical detail compared to conventional DIC and comparable visualization of the cystic duct-common bile duct junction to ERC.

Conclusions:

• DIC-SCT is a valuable, non-invasive tool for preoperative assessment in laparoscopic cholecystectomy.
• The technique provides detailed anatomical information, aiding in surgical planning.
• DIC-SCT can help minimize the risk of bile duct injury during surgery.
