Following hepatic resection, liver regeneration has been associated with concurrent splenic hypertrophy. The mechanisms of this phenomenon are unknown, may be multiple and include: splanchnic sequestration caused by a reduction in the hepatic mass; hepatic growth factors that may indirectly act on the spleen, and the redistribution of the total reticuloendothelial system. ⋯ Splenic hypertrophy occurred after major hepatectomy, but was not correlated to the extent of resection, by contrast with liver hypertrophy. Nevertheless, there was a linear correlation between splenic and liver hypertrophy. This correlation suggests the hypothesis of a splenic action of hepatic growth factors or a redistribution of the total reticuloendothelial system rather than an effect of reduction of the portal bed or hepatic outflow.

The aim was to assess the outcome of a total pancreatectomy (TP). ⋯ Morbidity and mortality rates of TP are acceptable, although diabetes- and TP-related mortality still occurs. Endocrine and exocrine insufficiency impacts on the long-term quality of life.

Prothrombin time-international normalized ratio (PT-INR) is widely utilized to guide plasma therapy and initiation of thromboprophylaxis after a hepatectomy. Thrombelastography (TEG) monitors shear elasticity, which is sensitive to cellular and plasma components in blood, allowing for functional assessment of the life of the clot. The objective of this study was to prospectively compare PT-INR and TEG in liver resection patients. ⋯ In spite of an elevation in PT-INR, patients undergoing a liver resection demonstrated a brief hypercoagulable state, followed by normal coagulation function based on TEG. These data call into question the practice of utilizing PT-INR to guide plasma transfusion and timing of prophylactic anticoagulation after a liver resection.

Assessing the impact of a fistula after a pancreaticoduodenectomy using the Post-operative Morbidity Index.
The Post-operative Morbidity Index (PMI) is a quantitative utility measure of a complication burden created by severity weighting. The Fistula Risk Score (FRS) is a validated model that predicts whether a patient will develop a post-operative pancreatic fistula (POPF). These novel tools might provide further discrimination of the ISGPF grading system. ⋯ These data quantitatively reinforce the ISGPF grades that were developed qualitatively around the concept of clinical severity. CR-POPFs usually reflect the patient's highest Accordion score whereas biochemical POPFs are often superseded. The correlation between FRS and PMI indicates that risk factors for a fistula contribute to overall pancreaticoduodenectomy morbidity.

Simultaneous colorectal and hepatic surgery for colorectal cancer (CRC) is increasing as surgery becomes safer and less invasive. There is controversy regarding the morbidity associated with simultaneous, compared with separate or staged, resections. ⋯ Hospitals in the NSQIP are performing more simultaneous colonic and hepatic resections for CRC. These procedures are associated with increases in operative time, length of stay and rate of perioperative complications. Simultaneous procedures do not, however, increase perioperative mortality.
