Comparative Study
Resident participation in index laparoscopic general surgical cases: impact of the learning environment on surgical outcomes.
The NSQIP database enables measurement of postoperative outcomes across a spectrum of practice settings. This allows for observations about potential effects of resident participation in surgical care during training. ⋯ Resident participation increases operative times for laparoscopic surgery considerably. Morbidity is statistically higher with resident participation but differences are unlikely to be clinically significant. Resident participation is a surrogate for the learning environment. These findings provide impetus for additional development of training techniques that occur outside the operating room.

The decision to transfuse packed RBCs (PRBC) during initial resuscitation of trauma patients is based on physiologic state, evidence for blood loss, and potential for ongoing hemorrhage. Initial hematocrit (Hct) is not considered an accurate marker of blood loss. This study tests the hypothesis that admission Hct is associated with transfusion requirements after trauma. ⋯ Admission Hct is more strongly associated with the PRBC transfusion than either tachycardia, hypotension, or acidosis. Admission Hct is also correlated with 24-hour blood product requirements in those receiving early transfusions. These findings challenge current thinking and suggest that fluid shifts are rapid after trauma and that Hct can be important in initial trauma assessment.

Bone marrow dysfunction is common in severely injured trauma patients, with release of hematopoietic progenitor cells (HPC) into the peripheral blood. Granulocyte colony stimulating factor (G-CSF) is a potent stimulator of HPC mobilization. We hypothesized that plasma G-CSF levels are elevated after trauma and correlate with postinjury anemia and infection. ⋯ Plasma G-CSF is markedly elevated after injury and is greater in patients who present in shock. The rise in G-CSF was also associated with prolonged mobilization of HPC. Elevation of G-CSF in humans after severe trauma may play a significant role in the development of post-traumatic bone marrow dysfunction, anemia, and infection.

Congenital diaphragmatic hernia (CDH) and esophageal atresia (EA) are fairly common congenital anomalies, but the occurrence of both is exceedingly rare, with only anecdotal cases reported in the English literature. The primary objective of the current study is to assess the incidence and outcomes of CDH/EA using the Congenital Diaphragmatic Hernia Study Group registry. ⋯ In patients with both CDH and EA, survival is significantly lower than other patients with CDH, but not uniformly lethal, therefore, intent to treat is a viable approach. Although the association of CDH with EA has a substantial impact on survival, it is the presence of low birth weight, cardiac and chromosomal abnormalities, surfactant use, and larger defects--and not the mere presence of EA--that influences the outcomes of this unique cohort.

Surgical site infections (SSI) are a major cause of morbidity in surgical patients and they increase health care costs considerably. Colorectal surgery is consistently associated with high SSI rates. No single intervention has demonstrated efficacy in reducing colorectal SSIs. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is a nationally validated system that uses clinically abstracted data on surgical patients and their outcomes to assist participating institutions drive quality improvement. ⋯ Using our ACS NSQIP colorectal SSI outcomes, a multidisciplinary team designed a colorectal SSI reduction bundle that resulted in a substantial and sustained reduction in SSIs. Our study is not able to identify which specific elements contributed to the reduction.
