We aimed to determine the effect of hospital volume on in-hospital mortality, and failure to rescue following major pancreatic resections using hospital discharge data of every inpatient case in Germany. ⋯ In Germany, patients who are undergoing major pancreatic resections have improved outcomes if they are admitted to higher volume hospitals. As current health policies failed to centralize pancreatic surgery procedures in Germany, new strategies to initiate a sufficient centralization process in the field of pancreatic surgery are needed.

Bioengineering of viable, functional, and implantable human lung grafts on porcine matrix. ⋯ Engineering and transplantation of viable lung grafts based on decellularized porcine lung scaffolds and human endothelial and epithelial cells is technically feasible. Further graft maturation will be necessary to enable higher-level functions such as mucociliary clearance, and ventilation-perfusion matching.

To determine the effect of cumulative volume on all-cause morbidity and operative time. ⋯ The present study demonstrated the clear, substantial influence of surgeon cumulative volume on improved perioperative outcomes and operative time. This finding emphasizes role of the individual surgeon in perioperative outcomes and that the true learning curve needed to master a complex surgical procedure such as gastric bypass is longer than previously thought, in this case requiring approximately 500 cases to plateau.

We aimed to characterize the landscape of surgeon participation in early accountable care organizations (ACOs) and to identify specialty-, organization-, and market-specific factors associated with ACO participation. ⋯ We observed considerable variation in ACO enrollment among US surgeons, mediated at least in part by differences in practice organization. These data underscore the need for development of frameworks to characterize the strategic advantages and disadvantages associated with APM participation.

To determine if laparoscopic pancreaticoduodenectomy (LPD) is safe and offers benefits over open pancreaticoduodenectomy (OPD) at institutions with lower pancreaticoduodenectomy (PD) volume. ⋯ These findings confirm that risks of postoperative mortality and suboptimal oncologic surgical quality following PD are higher in low-volume hospitals. Furthermore, these risks are more profound with LPD compared with OPD. These data suggest that the putative benefits of LPD are unlikely to be observed in institutions performing ≤25 PDs per year.
