Considerable debate exists regarding the definition, skill set, and training requirements for the new specialty of acute care surgery (ACS). We hypothesized that a patient subset could be identified that requires a level of care beyond general surgical training and justifies creation of this new specialty. ⋯ ACS and EGS patients represent distinct patient cohorts, as reflected by significant differences in critical care needs, likelihood of multiple operations, and need for postdischarge rehabilitation. The skills required to care for ACS patients, including ability to rescue from complications and provide critical care, differ from those required for EGS patients and supports development of ACS training and regionalization of care.

Previous studies have demonstrated that ultrasonographic measurement of the inferior vena cava diameter is a useful tool for the evaluation of intravascular volume status in preoperative patients. However, ultrasonographic measurement of inferior vena cava diameter could be limited by factors including obesity, bowel gas, or complex abdominal wounds. Our study sought to determine whether subclavian vein (SCV) diameter measured by ultrasound correlate with central venous pressure (CVP), as another indicator of intravascular volume status in patients undergoing gastrointestinal surgery. ⋯ SCV diameter is consistently low in patients undergoing gastrointestinal surgery as compared with healthy subjects. Measuring the SCV diameter maybe an important addition to the ultrasonographic evaluation of hypovolemia and other potentially volume-depleted patients.

Comparative Study
Early versus late hospital readmission after pancreaticoduodenectomy.
Most studies focus on readmission within 30 d of surgery and may therefore underestimate the true burden of readmission after complex procedures. We therefore sought to explore factors associated with readmission within 90 d of discharge after pancreaticoduodenectomy (PD). ⋯ Readmission within 30 d after PD was associated with patient- and procedure-related factors. Readmission in the 31-90-d window was not associated with patient- or procedure-related factors and may be influenced by the underlying pathology or subsequent medical management for that disease.

In patients with chronic severe aortic regurgitation (AR), aortic valve replacement (AVR) has been proved to promote left ventricular (LV) remodeling, especially LV end-diastolic dimension (LVEDD) reduction. However, there is little research whether postoperative LVEDD could return to normal parameter after AVR. The objective of this study was to determine predictors for the recovery of dilated LVEDD early after AVR. ⋯ In patients with chronic pure AR, preoperative EF may be a good predictor for successful recovery of dilated LVEDD early after AVR.
