Figure 1 Several typical computed tomography changes of postpancreatectomy acute pancreatitis. A: Peripancreatic fluid extravasation: Indicated by arrows as exudation belt; B: Residual peripancreatic fluid collection: Indicated by arrows as low-density fluid accumulation; C: Edema: Noticeable increase in the diameter of the pancreatic body and tail compared to preoperative dimensions; D: Necrotizing pancreatitis: Low-density shadow near the splenic hilum in the pancreatic tail.
