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.
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.
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.
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.
