Background:
Endoscopic treatment of pancreatic pseudocysts via cystoenterostomy or transpapillary stenting has been recognized as a successful treatment options in carefully selected patients. Transpapillary stenting is an option in patients with pancreatic pseudocysts directly communicating with the main duct.
Aim:
The aim of this study was to assess the safety and usefulness of transpapillary pancreatic endoprosthesis and transmural drainage in the treatment of symptomatic pancreatic pseudocysts.
Patients And Methods:
After preliminary endoscopic retrograde pancreatography (ERCP) in 22 patients, transpapillary drainage was attempted in 8 patients with pseudocysts that communicated with the main pancreatic duct, transmural drainage of pseudocysts in contact with the stomach or duodenal wall was attempted in 12 patients and 2 patients were selected for combined transpapillary and transmural drainage.
Results:
Endoscopic drainage was technically successful in 18 patients (81.8%) of whom 16 had complete pseudocyst resolution. Complications occurred in 9% and included bleeding (n = 1) after transmural drainage, and pancreatitis (n = 1) after transpapillary drainage. Mean follow-up was 12 months (range, 2 to 21); pseudocysts recurred in 2 patients (11%), whom required surgical intervention. No mortality was observed.
Conclusion:
Both transpapillary and transmural pseudocysts drainage are highly effective in patients with pseudocysts demonstrating suitable anatomy for these endoscopic techniques.
