Percutaneous vs surgical management of World Health Organization cystic echinococcosis 1 and 3a liver hydatid cysts

Figure 1 Ultrasound images before and after secondary catheterization in a 21-year-old patient treated percutaneously for a cystic echinococcosis 1 cyst who developed recollection. The cyst volume decreased from 480.1 mL to 65.3 mL (86.4% reduction) two months after catheterization. The aspirated material was bilious, and the fistula closed spontaneously without endoscopic retrograde cholangiopancreatography. The cause of recollection was bile leakage into the cavity through small bile ducts (Paired-Samples T test, P < 0.001).
