Endosonography-assisted transmural endoscopic drainage of pancreatic pseudocysts: a single center experience.

BACKGROUND/AIMS Management of pancreatic pseudocysts can be challenging. Endosonography-guided drainage of the pseudocysts is an important treatment modality. In this study, we evaluated the results of endosonography-guided transmural endoscopic drainage of these lesions. MATERIALS AND METHODS We performed drainage of the pancreatic pseudocysts through the stomach or duodenum using a linear endosonography device. The procedure steps were as follows: Determination of the best location for needle insertion, puncture of the cyst, guide insertion, creation of a window between the cyst and stomach lumen using a cystotome, and finally insertion of a double pigtail catheter. RESULTS The procedure was applied to 12 patients (8 males, 4 females, mean age: 51 ± 15.6 years), with success achieved in 10 patients (83%), defined as complete disappearance of the cyst. The mean cyst diameter was 9 cm (range: 6-12 cm). There was only one complication (8%), as an intraabdominal abscess with an uncomplicated course after surgical drainage. CONCLUSIONS Endosonography-guided drainage is an effective and safe method for the management of pancreatic pseudocysts.
