    Abstract:
    BACKGROUND: Endoscopic drainage of pancreatic pseudocysts is a new nonsurgical treatment modality. We retrospectively studied the efficacy of endoscopic drainage of pseudocysts in 37 patients with chronic pancreatitis. METHODS: Endoscopic retrograde pancreatic drainage was performed in 12 patients, endoscopic cystogastrostomy in 10 patients, and endoscopic cystoduodenostomy in 7 patients. In the remaining 8 patients, combinations of drainage routes were used. RESULTS: ECG failed in 3 patients. Procedure-related complications were seen in 6 patients: bleeding in 3, perforation in 2, and apnea in 1 patient. There was no procedure-related mortality. Seven patients had complications in relation to stents or drains: pseudocyst infection due to stent clogging in 2, stent migration in 4, and kinking of the drain in 1 patient. Twenty-four patients had complete resolution of pseudocysts, 7 had partial resolution, and 6 had no resolution. Three patients had pseudocyst recurrences. Mean follow-up was 32 months. Finally, 10 patients underwent surgery. CONCLUSIONS: Endoscopic drainage was technically feasible in 92% of the patients. Procedure-related morbidity was 16% and mortality was 0%. Endoscopic drainage was a definitive treatment for two thirds of the patients (65%). Surgery can be reserved for those patients in whom endoscopic therapy fails.
