Review Meta AnalysisPancreaticojejunostomy versus pancreaticogastrostomy.
In the majority of reports morbidity after pancreaticoduodenectomy remains high and leakage from the pancreatic stump still accounts for the majority of surgical complications. Many technical modifications of the pancreaticoenteric anastomosis to decrease the pancreatic leakage rate have been suggested. ⋯ Pancreaticojejunostomy appears to be the most widely performed reconstruction, but pancreaticogastrostomy is a reasonable alternative. However, in the analysis of the clinical results it is important to know which specific pancreaticoenteric anastomosis is considered; for example, end-to-end, dunking, invagination of the pancreatic stump, or duct-to-mucosa. It is hoped that collaborative trials will provide high-level data to allow tailoring of the operative technique, depending on the risk factors for pancreatic leakage in any particular patient.

ReviewUse of pancreatic duct stents after pancreaticoduodenectomy.
After pancreaticoduodenectomy, the pancreatic anastomosis carries the highest risk of leak and cause of morbidity and mortality. In this review article, three randomized controlled clinical trials and a fourth prospective trial focused on pancreaticoduodenectomy that contribute to level-one evidence are examined. The Johns Hopkins group demonstrated that internal pancreatic duct stenting did not decrease the frequency or severity of postoperative pancreatic fistulas. ⋯ The University of Athens group demonstrated that internal stenting of the pancreaticojejunostomy anastomosis did not reduce the incidence of pancreatic fistula and related complications. Finally, the French Surgery Research Group demonstrated that the use of an external stent through the pancreatic anastomosis reduced the pancreatic fistula rate. In summary, two studies do not demonstrate an advantage to the use of internal pancreatic duct stents and two studies demonstrate a possible advantage to the use of external pancreatic duct stents, especially in highest risk patients with soft glands and small pancreatic ducts.
