Risk Models for Developing Pancreatic Fistula After Pancreatoduodenectomy: Validation in a Nationwide Prospective Cohort.

Objective: To evaluate the performance of published fistula risk models by external validation, and to identify independent risk factors for postoperative pancreatic fistula (POPF).

Background: Multiple risk models have been developed to predict POPF after pancreatoduodenectomy. External validation in high-quality prospective cohorts is, however, lacking or only performed for individual models.

Robotic Developments in Cancer Surgery.

Indications for robotic surgery have been rapidly expanding since the first introduction of the robotic surgical system in the US market in 2000. As the robotic systems have become more sophisticated over the past decades, there has been an expansion in indications. Many new tools have been added with the aim of optimizing outcomes after oncologic surgery.
