Routine laparoscopic ultrasonography in biliary surgery. A preliminary experience

Area of Science:

• Surgical Innovation
• Medical Imaging
• Gastrointestinal Surgery

Background:

• Laparoscopic cholecystectomy is a common procedure.
• Intraoperative imaging of the biliary tract is crucial for safety.
• Current imaging methods may have limitations in laparoscopic settings.

Purpose of the Study:

• To describe a new technique for intraoperative imaging of the biliary tract during laparoscopic cholecystectomy.
• To evaluate the feasibility and quality of this new ultrasonographic method.

Main Methods:

• Development of a specifically designed laparoscopic ultrasonographic probe.
• Utilizing the probe to obtain transverse and longitudinal views of the extrahepatic biliary tract.
• Application of the technique in a series of 28 patients.

Main Results:

• Successful implementation of the new ultrasonographic imaging technique in all 28 patients.
• Achieved ultrasonographic imaging quality comparable to intraoperative ultrasonography in open biliary surgery.
• Demonstrated ability to visualize the entire extrahepatic biliary tract.

Conclusions:

• The described laparoscopic ultrasonographic technique is effective for intraoperative biliary tract imaging.
• The imaging quality is on par with established methods used in open surgery.
• Ultrasonography may offer advantages over cholangiography in laparoscopic biliary surgery, similar to open procedures.
