Therapeutic Interventional Endoscopic Ultrasound Based on Rare Cases in Indonesia: A Single-Center Experience in Unselected Patients

BACKGROUND: Endoscopic ultrasound (EUS) is still not widely available and has a barrier in most Southeast Asian countries due to lack of training program, high cost, and hospital investment. In this study, we would like to show the impact of therapeutic interventional EUS procedures in gastroenterology practice in Indonesia, which represents the biggest Southeast Asian country. METHODS: Patients who underwent interventional EUS procedure in Medistra Hospital were prospectively recruited within 1 year. RESULTS: Of 147 patients who underwent EUS procedures, 39 patients underwent fine needle aspiration. Most of the cases suffered from pancreatic cancer (47.5%) followed by ampullary cancer (20%), gastric subepithelial mass (10%), and other conditions. There were 4 rare cases that underwent therapeutic interventional EUS procedures. Patients with large mesenteric cyst attached to the gastric wall and large left liver lobe cyst with gastric compression who were previously suspected with gastrointestinal stromal tumor were successfully managed by cyst aspiration. One patient with a large pseudocyst due to chronic pancreatitis was successfully managed by plastic stent placement. Another patient with duodenal duplication cyst causing duodenal obstruction was managed by inserting a plastic stent through the cyst. No complications were observed during and after the therapeutic EUS procedures. CONCLUSIONS: Innovation in interventional EUS has a high impact in gastroenterology practice as well as in a developing country like Indonesia, which represents the biggest Southeast Asian country. Further developments are needed regarding the cost, investment, and especially the necessary training curriculum to make this technology available in tertiary referral centers.
