Summary

Operative contrast-enhanced ultrasound (CEUS) provided valuable intraoperative information in 86.4% of general surgical procedures. This advanced imaging technique altered surgical management in 27.2% of cases, improving vessel visualization and tumor assessment.

Area of Science:

  • Surgical Imaging
  • Medical Ultrasound

Background:

  • B-mode imaging has limitations in visualizing small blood vessels and differentiating them from other structures during surgery.
  • Accurate intraoperative assessment of vascularity and tumor-vessel relationships is crucial for surgical success.

Purpose of the Study:

  • To evaluate the utility and impact of operative contrast-enhanced ultrasound (CEUS) in general surgical operations.
  • To compare the advantages of operative CEUS over traditional B-mode imaging.

Main Methods:

  • Operative CEUS was performed during 125 general surgical procedures across various specialties.
  • Data collected included the provision of beneficial information and alterations in surgical management based on CEUS findings.

Main Results:

Related Experiment Videos

  • Operative CEUS provided beneficial information in 108 of 125 operations (86.4%).
  • Surgical management was altered in 34 of 125 operations (27.2%), particularly in hepatic and pancreatic surgeries.
  • CEUS offered superior detection of small vessels, differentiation from other structures, assessment of tumor vascular invasion, confirmation of organ perfusion, and needle guidance.

Conclusions:

  • Operative CEUS is a valuable tool in general surgery, offering significant advantages over B-mode imaging.
  • CEUS enhances intraoperative decision-making, particularly in complex cases involving vascular structures and tumors.
