ABSTRACT
Objective To evaluate the clinical value of infusing dehydrated alcohol on pancreatic pseudocyst (PPC). Methods Twenty one patients with D'Egidio type I PPC underwent CT or ultrasound (US) guided percutaneous catheter drainage, and CT or US were used to re-evaluate the efficacy of drainage. If no residual cavity was observed, the drainage tube was clamped for 3~7 d, and then the tube would be pulled out. Non-curative cases with catheter drainage for 21 days were given dehydrated alcohol 20 ml infusion. Results The curative rate by using percutaneous catheter drainage was 71.43% (15/21). Among the remaining 6 patients, the treatment was effective in 3 patients and ineffective in other 3 patients. 2 cases of non-infective mutli-antrum pancreatic pseudocyst, 1 case of infective single antrum and 3 cases of infective multi-antrum were included in the 6 non-curative cases, and all of them recovered completely 6~21 d after dehydrated alcohol infusion. No complication and recurrence were found during the 6~12 follow-up. Conclusions Percutaneous puncture and dehydrated alcohol infusion for infective or mufti-antrum pancreatic pseudocyst was effective and safe.
