Abstract:
Objective To introduce the techniques of scanning the common bile duct(CBD) in full length with laparoscopic ultrasonography through the sonic window dorsal to the first portion of the duodenum(FPD). Methods The lower segment of the CBD in 300 cases was scanned in full length through the sonic window dorsal to the FPD. Results In our series, 97.67% of the lower segment of the CBD can be visualized with simple techniques through sonic window dorsal to the FPD. Visualization in 25 cases were improved with injection of saline into the subhepatic space and extraction of gas from the stomach and duodenum. Conclusion Through the sonic window dorsal to the FPD and with simple techniques, the lower segment of the CBD in majority of our cases can be satisfactorily imaged in full length. Visualization can be improved in some individuals with injection of saline into the subhepatic space and extraction of gas from the stomach and duodenum.
