The incidence of retroperitoneal abscess with fistula formation after acute pancreatitis is rare, but the mortality rate for patients with this condition is very high. The standard treatment for this condition has been surgical removal and drainage. However, recent studies have shown that percutaneous catheter drainage or noninvasive endoscopic abscess drainage with using endoscopic ultrasonography is effective and safe for the treatment of pancreatic and peripancreatic abscess. A retroperitoneal abscess with duodenal fistula that developed after acute pancreas and its endoscopic treatment has never been reported on in Korea. We experienced a 45-year-old man who had been treated for acute pancreatitis at other hospital, and he was then referred to our hospital and diagnosed as having a retroperitoneal abscess with fistula, which communicated with the third portion of duodenum, as assessed by abdominal CT and duodenoscopy. So we treated him with endoscopic double-pigtailed stent insertion through the fistulous tract and we drained the abscess. Endoscopic drainage may be a suitable alternative for the management of the retroperitoneal abscess with fistula that develops after acute pancreatitis.
