FIGURE 5.

A DGE case caused by AP with WON was treated by lavage with large-bore catheter. A, 7 days after the onset of AP, the CECT showed significant amounts of fluid accumulated inside and around the pancreas. B, 30 days after the onset, both DGE and WON were seen. Two PCD catheters were placed and intermittent lavage was performed. One of the catheters was large bore. C, 42 days after the onset, DGE symptoms have been relieved, and WON at the head of the pancreas shrank considerably.
