Figure 2 Selection of the puncture site and procedure flow diagram. A: Endoscopic ultrasound (EUS)-pancreaticogastrostomy: Applicable when the obstruction is located at the head of the pancreas; B: EUS-pancreaticoduodenostomy: Applicable when the obstruction is located in the body or tail of the pancreas; C-F: EUS-guided rendezvous procedure flow diagram. Insert the ultrasound endoscope and select the puncture site (C), Perform the puncture and insert the guidewire through the duodenal papilla (D), Remove the endoscope (E), Switch to the ballon endoscope, align with the guidewire, and place the stent (F); G-J: EUS-transmural drainage procedure flow diagram. Insert the ultrasound endoscope and select the puncture site (G). Perform the puncture and insert the guidewire (H). Establish a channel between the stomach and pancreatic duct (I). Place the stent (J). Created in BioRender (Supplementary material).
