Two-step approach for recurrent pancreatic pseudocysts: endoscopic ring drainage of the stent transpapillary combined with the posterior gastric wall.

Pancreatic pseudocyst is a complication of pancreatitis, with an incidence of about 5-16% and a incidence of about 20-40% in chronic pancreatitis. There are various ways to treat pancreatic pseudocysts, but the recurrence rate of cysts is as high as 23.9%. There are not many clinical options for the treatment of recurrent pseudocysts, and there is still a high recurrence of pseudocysts after EUS guided drainage alone. We present here a promising endoscopic treatment for patients with recurrent pancreatic pseudocyst.
