We define in this paper different modalities of endoscopic treatment as well as the criteria for this procedure. Endoscopic drainage were done through cystoenterostomy and nasocystic drainage and enterocystic prosthesis plus sphincterostomy of the principal pancreatic and biliary duct, in all patients, but only in eleven of them we implanted the prosthesis in both ducts. The complication was bleeding, in two patients (16.7%) and they were treated with endoscopic inyectotherapy.
