INTRODUCTION The cystic tumor of the pancreas is a relatively uncommon entity. There are different types of pancreatic cystic tumors and they all exhibit different degrees of malignancy. These tumors represent 1% of all primary pancreatic tumors and only 15% of the cystic lesions. The serous cystadenomas (SCA) are mostly benign lesions with an average size(More)
TEM specimens of a LaAlO(3)/SrTiO(3) multilayer are prepared by FIB with internal lift out. Using a Ga(+1) beam of 5 kV, a final cleaning step yielding top, top-angle, side, and bottom-angle cleaning is performed. Different cleaning procedures, which can be easily implemented in a dual beam FIB system, are described and compared; all cleaning types produce(More)
OBJECTIVES The present study was designed to determine whether the surgeon factor has an independent effect on morbidity and mortality rates after duodenopancreatectomy. MATERIAL AND METHOD Between October 2002 and December 2006, we performed a study of 119 patients who underwent duodenopancreatectomy. The surgeons were divided into 3 groups according to(More)

The Vater's ampulla neoplasias are not very frequent lesions. The ampullectomy consists on the total resection of the Vater's ampulla and part of the duodenal wall with the later reconstruction and anastomosis of the common bile duct and the Wirsung's duct to the duodenum. The local resection of the ampulla is an alternative to the duodenopancreatectomy(More)
This case is about a one obesity patient to carry out pancreaticoduodenectomy for solido pseudopapilary cyst of the pancreatic head, considerate in pancreatic surgery like high risk for to present soft pancreatic, wirsung smaller to 2mm and not bile duct dilatation .The pancreaticojejunostomy was performed end to end with invagination of the pancreatic(More)
INTRODUCTION The pancreatojejunal anastomosis is considered the weak spot when carrying out a duodenopancreatectomy, because it causes most of the complications following a Whipple surgery. Here we present a series of cases using a single technique for performing this anastomosis. MATERIAL AND METHODS During the period between October 2002 and August(More)
