Summary
Intraoperative ultrasonography significantly improves the detection of liver lesions compared to preoperative methods. This advanced imaging is valuable for surgical planning and locating small tumors in hepatobiliary surgery.
Area of Science:
- Hepatobiliary Surgery
- Diagnostic Imaging
- Oncology
Background:
- Preoperative ultrasonography has limitations in detecting all liver lesions.
- Accurate intraoperative assessment is crucial for effective hepatobiliary surgery.
Purpose of the Study:
- To evaluate the diagnostic efficacy of intraoperative ultrasonography in hepatobiliary surgery.
- To compare its performance against preoperative ultrasonography.
Main Methods:
- Utilized Aloka-650 and Aloka-500 ultrasound devices.
- Employed varying probe frequencies (3.5 MHz preoperative, 5-7.5 MHz intraoperative).
- Pathological confirmation for all carcinoma cases.
Main Results:
- Intraoperative ultrasonography showed a higher diagnostic rate (97%) for liver cancers than preoperative (84%).
- Significantly improved detection of small tumors (
- High diagnostic rates for choledocholithiasis and biliary tract cancers, surpassing preoperative imaging.
Conclusions:
- Intraoperative ultrasonography enhances the detection of liver lesions compared to preoperative methods.
- It is a valuable tool for surgical strategy selection and precise localization of small lesions.
