Publications using the ALPPS (associating liver partition and portal vein ligation for a staged hepatectomy) procedure have demonstrated a future liver remnant growth of 40-160% in only 6-9 days. The present study aimed to develop and describe the first large animal model of ALPPS that can be used for future studies. ⋯ The present study describes the first reproducible large animal model of the ALPPS procedure. The degree of liver growth and the kinetic rate of growth were similar to that which has been demonstrated in human publications. This model will be valuable as future laboratory studies are performed.

Understanding factors associated with variation in hospital charges may help identify means to increase savings. The aim of the present study was to define potential variation in hospital charges associated with hepatopancreatobiliary(HPB) surgery. ⋯ After accounting for in-hospital complications, the total mean hospital charges for HPB surgery remained variable by case type and provider. While the variation in charges was associated with LOS, provider-level differences in across-the-board charges were also noted.

Peri-operative red blood cell transfusions (RBCT) may induce transfusion-related immunomodulation and impact post-operative recovery. This study examined the association between RBCT and post-pancreatectomy morbidity. ⋯ Peri-operative RBCT for a pancreatectomy was independently associated with worse short-term outcomes and prolonged LOS. Future studies should focus on the impact of interventions to minimize the use of RBCT after an elective pancreatectomy.

The prognostic value of CA19-9 in patients with pancreatic cancer (PC) treated with neoadjuvant therapy has not been well described. ⋯ Among patients who completed neoadjuvant therapy and surgery, pre-treatment CA19-9 obtained at the time of diagnosis was not predictive of overall survival, but normalization of post-treatment CA19-9 in response to neoadjuvant therapy was highly prognostic.

Small-for-size syndrome (SFSS) is a feared complication of extended liver resection and partial liver transplantation. Swine models of extended hepatectomy have been developed for studying SFSS and its different treatment options. Although portal inflow modulation (PIM) by splenectomy or splenic artery ligation (SAL) has been proposed in humans to prevent SFSS, such procedures have not yet been evaluated in swine. ⋯ Subtotal hepatectomy of 90% in swine is a reliable model for SFSS inducing a significant increase in HVPG. However, in view of the relevant differences between swine and human splanchnic anatomy, this model is inadequate for studying the effects of PIM by SAL and splenectomy.
