Summary
Extracorporeal shock wave lithotripsy (ESWL) for gallstones can cause gallbladder wall thickening in some patients. However, serious gallbladder and liver trauma from ESWL is infrequent, as shown by CT scans.
Area of Science:
- Radiology
- Gastroenterology
- Medical Imaging
Background:
- Gallstones are a common ailment requiring treatment.
- Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive method for gallstone treatment.
- Assessing the impact of ESWL on surrounding organs is crucial for patient safety.
Purpose of the Study:
- To evaluate the effects of ESWL on the gallbladder and adjacent liver tissue.
- To identify potential complications or abnormalities following ESWL treatment for gallstones.
- To determine the frequency of gallbladder and liver trauma associated with ESWL.
Main Methods:
- Computed tomography (CT) scans were performed on 88 patients.
- Imaging was conducted before and after ESWL treatment for gallstones.
- Scans were analyzed for changes in the gallbladder wall, liver tissue, and presence of complications.
Main Results:
- Gallbladder wall thickening was observed in 28.4% of patients post-ESWL.
- One case of intrahepatic bilioma was noted 3 days after treatment.
- No instances of gallbladder hematoma, liver hematoma, hydrops, or biliary pancreatitis were reported.
Conclusions:
- ESWL can lead to minor CT scan abnormalities in some patients.
- Serious gallbladder and liver trauma following ESWL is rare.
- CT imaging is valuable for monitoring post-ESWL changes and ensuring patient safety.
