In 5 of the 41 patients pylorus-preserving duodenopancreatectomy was applied.
      
If the histology of the ampullary lesion is uncertain, pylorus-preserving partial pancreaticoduodenectomy is justified in patients with low perioperative risks, and if this extended procedure can be done safely by an experienced surgeon.
      
Treatment consistedin subtotal pancreatoduodenectomy with pylorus resection.
      
Since the ethyl acetate-soluble fraction was found to be most active in the pylorus ligated model, this fraction was further investigated and resulted in the isolation of triterpene 3,15-dioxo-21α-hydroxy friedelane.
      
In a study compiling the data in a prospective manner, the value of the pylorus-preserving duodenopancreatectomy (PPPD) compared to partial duodenopancreatectomy (PD) in patients suffering from ductal pancreatic carcinoma was assessed.
      
However, the pylorus-preserving duodenopancreatectomy (PPPD) is supposed to be superior in gastrointestinal function.
