Intraoperative ultrasound assessment in management of complex pancreatic pseudocysts.

Preoperative imaging studies and operative inspection may provide insufficient information to appropriately manage certain complex pancreatic pseudocysts. Intraoperative ultrasound accurately identifies and localizes peripancreatic fluid collections, cyst wall thickness, parenchymal and ductal anatomy, and relationships to adjacent visceral and vascular structures. Adjunctive use of intraoperative ultrasonography altered the surgical management in the clinical case described herein and is advocated for assessment of problematic pancreatic pseudocysts.
