<qa>  What is the standard surgical procedure for?Pancreaticoduodenectomy is the standards surgical procedure for various malignant and benign disease of the pancreas and periampullariy region. During the recent years, mortality rate of pancreaticoduodenectomy has decreased to 5 in specialized centers. Although, this procedure still carries considerable morbidity up to 40, depending of definition of complications. Pancreatic fistula remains a common complication and the main cause of other morbidities and mortality. Pancreaticojejunal PJ anastomosis is the most often used method of reconstruction after pancreaticoduodenectomy. Several technique modifications such as placement of the stents, reinforcement of anasomosis with fibrin glue, pancreatic duct occlusion and pancreaticogastrostomy PG type of anastomosis was used in order to decrease pancreatic fistula rate. Since, some retrospective studies showed better results with some technique, several meta-analyses did not show any advantage of those various modifications. It was shown that the higher risk of pancreatic fistula was noticed in patients with soft residual pancreas and small diameter of pancreatic duct. There is only one randomized study in the literature dealing with this problem. This study did not reveal any significant differences between PG and PJ in patients with soft pancreas and small duct. In order to investigate once more this important issue, the researchers conducted randomized multicenter controlled trial.
