Dark green urine following endoscopic ultrasound-guided hepaticogastrostomy: A case report

Figure 2 The Endoscopic ultrasound-guided hepaticogastrostomy process and the stent position after the operation. A: Duodenal obstruction in the patient. Endoscopic view showing stenosis in the descending duodenum, precluding endoscopic retrograde cholangiopancreatography cannulation; B: Transgastric needle puncture. Ultrasonographic endoscopic puncture of the intrahepatic S2 segmental bile duct through the upper posterior wall of the gastric body under the cardia; C: Contrast injection. Successful injection of contrast agent (30% biligrafin) confirmings intrahepatic ductal access; D: Nasobiliary drainage placement; E: Snipped nasal bile duct for stent drainage; F: Final stent position under X-ray.
