EUS-guided cystojejunostomy for drainage of a pseudocyst in a patient with Billroth II gastrectomy.

摘要

EUS-guided transgastric or transduodenal drainage of pancreatic pseudocysts (PPs) has become a well-established therapeutic procedure. Moreover, sporadic cases of trans-esophageal drainage of PPs extending into the mediastinum have been also reported. In contrast, in patients with altered anatomy because of previous gastric surgery, EUS-guided transjejunal drainage has been described in only 1 patient with a Roux-en-Y anastomosis. This probably reflects the concern for possible complications, making a percutaneous or surgical approach preferable
