We think that all patients with advanced-stage carcinoid should be evaluated for possible multimodal surgical therapy. Primary tumors should be resected, even in the presence of distant metastases to prevent future intestinal obstruction. The "wait and see" method of management of this slow-growing cancer no longer has merit. We offer an algorithm for the surgical evaluation and management of these patients.
Pyloric exclusion (PEX) has traditionally been used in the management of complicated duodenal injuries to temporarily protect the duodenal repair and prevent septic abdominal complications. We used the American College of Surgeons National Trauma Data Bank (v 5.0) to evaluate adult patients with severe duodenal injuries [American Association for the Surgery of Trauma (AAST) Grade ≥ 3] undergoing primary repair only or repair with PEX within 24 hours of admission. Propensity scoring was used to adjust for relevant confounding factors during outcomes comparison. Among 147 patients with severe duodenal injuries, 28 (19.0%) underwent PEX [15.9% (11/69) Grade III vs 34.0% (17/50) Grade IV–V]. Despite similar demographics, PEX was associated with a longer mean hospital stay (32.2 vs 22.2 days, P = 0.003) and was not associated with a mortality benefit. There was a trend toward increased development of septic abdominal complications (intra-abdominal abscess, wound infection, or dehiscence) with PEX that was not statistically significant. After multivariable analysis using propensity score, no statistically significant differences in mortality or occurrence of septic abdominal complications was noted between those patients undergoing primary repair only or PEX. The use of PEX in patients with severe duodenal injuries may contribute to longer hospital stay and confers no survival or outcome benefit.
BACKGROUND
Patients' trauma burdens are a combination of anatomic damage, physiologic derangement, and the resultant depletion of reserve. Typically, Injury Severity Score (ISS) >15 defines major anatomic injury and Revised Trauma Score (RTS) <7.84 defines major physiologic derangement, but there is no standard definition for reserve. The Need For Trauma Intervention (NFTI) identifies severely depleted reserves (NFTI+) with emergent interventions and/or early mortality. We hypothesized NFTI would have stronger associations with outcomes and better model fit than ISS and RTS.
METHODS
Thirty-eight adult and pediatric U.S. trauma centers submitted data for 88,488 encounters. Mixed models tested ISS greater than 15, RTS less than 7.84, and NFTI's associations with complications, survivors' discharge to continuing care, and survivors' length of stay (LOS).
RESULTS
The NFTI had stronger associations with complications and LOS than ISS and RTS (odds ratios [99.5% confidence interval]: NFTI = 9.44 [8.46–10.53]; ISS = 5.94 [5.36–6.60], RTS = 4.79 [4.29–5.34]; LOS incidence rate ratios (99.5% confidence interval): NFTI = 3.15 [3.08–3.22], ISS = 2.87 [2.80–2.94], RTS = 2.37 [2.30–2.45]). NFTI was more strongly associated with continuing care discharge but not significantly more than ISS (relative risk [99.5% confidence interval]: NFTI = 2.59 [2.52–2.66], ISS = 2.51 [2.44–2.59], RTS = 2.37 [2.28–2.46]). Cross-validation revealed that in all cases NFTI's model provided a much better fit than ISS greater than 15 or RTS less than 7.84.
CONCLUSION
In this multicenter study, NFTI had better model fit and stronger associations with the outcomes than ISS and RTS. By determining depletion of reserve via resource consumption, NFTI+ may be a better definition of major trauma than the standard definitions of ISS greater than 15 and RTS less than 7.84. Using NFTI may improve retrospective triage monitoring and statistical risk adjustments.

Prognostic, level IV.
In this single-center experience, Acinetobacter baumannii infection, including multidrug-resistant strains, has inconclusive impact on mortality in a cohort of trauma patients. Larger studies are needed to support a definite conclusion. Acinetobacter baumannii infection was, however, associated with a longer intensive care unit stay and a higher rate of organ failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
