Pancreatic surgeries, such as pancreaticoduodenectomy and distal pancreatectomy, are associated with high morbidity and mortality. The most common cause of this morbidity is postoperative pancreatic fistula(POPF). The risk of POPF depends on the texture of pancreatic parenchyma, the size of the main pancreatic duct, and the technique of pancreatic-enteric reconstruction. There are several techniques for pancreaticojejunostomy anastomosis. Among which duct to mucosa is considered a relatively safe anastomosis technique. However, there are several modifications to the duct-to-mucosa technique. The investigators of this study believe that the modified Cattell-Warren duct-to-mucosa technique, which includes taking more than 5 mm of periductal pancreatic parenchyma with the duct and the full-thickness jejunum while performing pancreaticojejunostomy reconstruction with proper perioperative nutritional optimization and prehabilitation, improves patient outcomes. So the investigators aim to assess the risk of POPF in the novel modified Cattell-Warren technique.
