Per journal article "kahaleh et al.2006 ¿endoscopic ultrasound drainage of pancreatic pseudocyst: a prospective comparison with conventional endoscopic drainage.¿ endoscopic management of pseudocysts by a conventional transenteric technique, i.E.Conventional transmural drainage (ctd), or by endoscopic ultrasound-guided drainage (eud), is well described.Our aim was to prospectively compare the short-term and long-term results of ctd and eud in the management of pseudocysts.A total of 99 consecutive patients underwent endoscopic management of pancreatic pseudocysts according to this predetermined treatment algorithm: patients with bulging lesions without obvious portal hypertension underwent ctd; all remaining patients underwent eud.46 patients (37 men) underwent eud and 53 patients (39 men) had ctd.All ctd cystoenterostomy fistulas were created using a 10-fr cystoenterostome (wilson-cook medical and endo-flex instrumente, voerde, germany) [15].Following access to the pseudocyst, one or two 10-fr double-pigtail endoprostheses were placed.Bleeding was defined as any hemorrhagic event occurring during or after the procedure that required any intervention or blood transfusion.One patient developed bleeding of the cystoenterostomy site that responded to balloon tamponade.
