Advanced Diagnostic & Interventional Radiology Research Center | Short- and Long-Term Outcome of Balloon of Benign Biliary Stric

COVID-19 pandemic

During the COVID-19 pandemic, the Radiology Research Center at Tehran University of Medical Sciences continued its research activities despite the challenges posed by the increased demand for CT scans of COVID-19 patients and the necessity of adhering to strict health protocols. This center played a crucial role in improving medical imaging techniques, optimizing diagnostic protocols, and advancing technologies related to CT scan image analysis.

Faculty members, researchers, and staff remained committed to ensuring the safety and well-being of healthcare professionals and patients while actively engaging in imaging data analysis, developing artificial intelligence algorithms for faster disease detection, publishing scientific articles, and presenting their findings at international conferences. These efforts aimed to enhance diagnostic accuracy, improve treatment processes, and alleviate pressure on healthcare systems.

Key achievements of the Radiology Research Center during the COVID-19 pandemic include:

✔️ Development and optimization of lung imaging protocols for faster and more accurate COVID-19 diagnosis
✔️ Implementation of artificial intelligence technologies for automated CT scan analysis and reduced diagnosis time
✔️ Publication of high-impact research articles on innovative imaging methods for COVID-19 patients
✔️ Participation in national and international projects focused on COVID-19 diagnosis and patient management

The center remains dedicated to advancing research in medical imaging and continues to contribute as a leading scientific institution in improving the quality of diagnostic and therapeutic services.

Short- and Long-Term Outcome of Balloon Dilatation of Benign Biliary Strictures

Short- and Long-Term Outcome of Balloon Dilatation of Benign Biliary {faces}

Background:

The rate of benign biliary strictures has increased in recent years.

Objectives:

We studied the short- and long-term efficacy of biliary balloon dilatation in patients suffering from benign biliary strictures due to prior abdominal surgeries, such as laparoscopic cholecystectomy or liver transplantation.

Patients and Methods:

An initial baseline biochemistry profile and ultrasound examination of the biliary system was done before each procedure, and 3 and 6 month follow-up sessions were completed after the completion of the biliary balloon dilatation procedure. Serum bilirubin, liver enzyme levels, and ultrasonography findings were investigated during every session.

Results:

Twenty four patients, 17 females (70.8%) and 7 males (29.2%), were included in this study. In 21 (88%) of the patients, the biliary stricture was developed after a laparoscopic cholecystectomy, while in 2 (8%) it was a complication of a liver transplantation. The remaining patients (4%) developed it after autoimmune pancreatitis (Whipple surgery). Among the 24 patients, 2 died within 2 months after the ballooning, mainly due to complications of their previous surgery and secondary liver cirrhosis. We found a significant decrease in serum bilirubin levels after balloon dilatation (P < 0.0001). All the patients showed normal ultrasonography findings after the procedure, and all reported complete relief of symptoms after a 6-month period.

Conclusion:

Serum bilirubin levels were significantly decreased after balloon dilatation. This procedure has led to a success rate of 95% in the short term and 91% in the long term
