Summary
Percutaneous transhepatic dissolution using methyl tert-butyl ether (MTBE) effectively treated cholesterol gallstones in 85.5% of patients. This minimally invasive procedure offered a successful alternative to surgery for many, with short hospital stays.
Area of Science:
- Gastroenterology
- Minimally Invasive Procedures
- Medical Technology
Background:
- Symptomatic cholesterol gallstones pose a significant health concern.
- Surgical intervention has traditionally been the primary treatment for gallstones.
- Alternative, less invasive methods are sought for gallstone management.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous transhepatic dissolution with methyl tert-butyl ether (MTBE) for cholesterol gallstones.
- To assess patient preference for MTBE dissolution over surgical treatment.
- To determine the success rate and complication profile of the MTBE dissolution procedure.
Main Methods:
- Percutaneous transhepatic catheter placement into the gallbladder lumen.
- Dissolution of cholesterol gallstones using methyl tert-butyl ether (MTBE).
- Post-treatment imaging (roentgenograms and ultrasound) to assess dissolution and residual particles.
Main Results:
- Successful gallbladder puncture and catheter placement in 91% of patients.
- Complete gallstone dissolution achieved in 85.5% of treated patients.
- A mean hospitalisation duration of 4.5 days for successfully treated patients.
Conclusions:
- Percutaneous transhepatic MTBE dissolution is an effective treatment for cholesterol gallstones.
- The procedure demonstrates a high success rate and is preferred by patients over surgery.
- Minor residual particles were noted in a subset of patients, warranting further monitoring.
