Sequential therapy with combined trans-papillary endoscopic naso-pancreatic and endoscopic retrograde pancreatic drainage for pancreatic pseudocysts

Figure 3 Three cyst types (Xinqiao classification) based on the relationship between the pancreatic pseudocyst and the splenic vein (the orange line on the horizontal axis is the splenic vein plane, and the white line on the vertical axis indicates the distance between the cyst and the splenic vein plane). Type I: Pancreatic pseudocyst above the splenic vein plane; Type II: Pancreatic pseudocyst located partially above the splenic vein and partially within 3 cm below the splenic vein; Type III: Pancreatic pseudocyst located below the splenic vein (greater than 3 cm or the entire cyst is below the splenic vein).
