RESUMEN
INTRODUCTION: Necrotizing soft tissue infections (NSTIs) are surgical emergencies associated with high morbidity and mortality. Identifying risk factors for poor outcome is a critical part of preoperative decision-making and counseling. Sarcopenia, the loss of lean muscle mass, has been associated with an increased risk of mortality and can be measured using cross-sectional imaging. Our aim was to determine the impact of sarcopenia on mortality in patients with NSTI. We hypothesized that sarcopenia would be associated with an increased risk of mortality in patients with NSTI. METHODS: This is a retrospective cohort study of NSTI patients admitted from 1995 to 2015 to two academic institutions. Operative and pathology reports were reviewed to confirm the diagnosis in all cases. Average bilateral psoas muscle cross-sectional area at L4, normalized for height (Total Psoas Index [TPI]), was calculated using computed tomography (CT). Sarcopenia was defined as TPI in the lowest sex-specific quartile. Primary outcome was in-hospital mortality. Multivariate logistic regression was performed to assess the association between sarcopenia and in-hospital mortality. RESULTS: There were 115 patients with preoperative imaging, 61% male and a median age of 57 y interquartile range (IQR 46.6-67.0). Overall in-hospital mortality was 12.1%. There was no significant difference in sex, body mass index (BMI), comorbidities and American Society of Anesthesiologists classification (Table 1). After multivariate analysis, sarcopenia was independently associated with increased in-hospital mortality (Odds ratio, 3.5; 95% Confidence Interval [CI], 1.05-11.8). CONCLUSIONS: Sarcopenia is associated with increased risk of in-hospital mortality in patients with NSTIs. Sarcopenia identifies patients with higher likelihood of poor outcomes, which can possibly help surgeons in counseling their patients and families.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric surgical procedure. Little is known about how surgeon training background influences the learning curve of this procedure. We examined operating times (OT), weight loss outcomes, and 30-day complications between surgeons with and without fellowship training in LSG. We hypothesize that post-residency training specific to LSG influences learning curves. METHODS: Surgeons from a single institution were split into two groups: those who had not completed fellowship training in LSG (NF, n = 3), and those who had completed LSG specific training in fellowship (SGF, n = 3). OTs, BMI changes at 1 year, and 30-day readmissions, reoperations, and complications were extracted for the first 100 LSG cases of each surgeon. Data were analyzed in bins of 20 cases. Comparisons were made between cohorts within a bin and between adjacent bins of the same surgeon cohort. Logistic regression analyses were performed of OT and weight loss outcomes. RESULTS: SGF surgeons showed no difference in OTs over their first 100 cases. NF surgeons had statistically significant increased OTs compared to SGF surgeons during their first 60 cases and progressively shortened OTs during that interval (109 min to 78 min, p < 0.001 for NF surgeons vs. 73 min to 69 min, SGF surgeons). NF surgeons had a significantly steeper slope for improvement in OT over case number. There was no correlation between case number and weight loss outcomes in either group, and no differences in 30-day outcomes between groups. CONCLUSION: Surgeons who trained to perform LSG in fellowship demonstrate faster and consistent OR times on their initial independent LSG cases compared to surgeons who did not, with no correlation between case number and weight loss outcomes or safety profiles for either group. This suggests that learning curves for LSG are achieved during formal case-specific fellowship training.

BACKGROUND: Traumatic brain injury (TBI) is common, and significant institutional variation exists with regards to structure and processes of care. Affected patients may be admitted to one of several different services, and this may drive differential care and outcomes. We sought to evaluate differential care and outcomes for patients with isolated mild-to-moderate traumatic brain injury based on admission service. MATERIALS AND METHODS: This is a single-institution retrospective study of all adult (≥18 y old) patients admitted with isolated TBI (AIS ≤1 in all other body regions) over a 3-year period (6/2015-6/2018). Patients who underwent neurosurgical intervention (craniectomy/craniotomy) and those with a head AIS ≥4 were excluded. Patients were assigned to one of three groups based upon admission service: Trauma Surgery, Neurology/Medicine or Neurosurgery. Outcomes evaluated included in-hospital mortality and markers of differential care. We performed multivariate analyses adjusting for patient demographics and clinical characteristics. RESULTS: A total of 401 isolated mild-to-moderate TBI patients were identified. Overall mortality was 1.7%. Adjusted multivariate logistic regression analysis demonstrated no difference in mortality. Patients admitted to Neurosurgery underwent more repeat head CTs and were more likely to receive antiseizure medication in the absence of seizure activity, and those admitted to Neurology/Medicine were less likely to receive venous thromboembolism chemoprophylaxis compared to those admitted to Trauma Surgery. CONCLUSIONS: We identify several important metrics of variation in care received by patients with an isolated mild-to-moderate TBI based upon admission service. These findings deserve further study, and this study may lay the foundation for future efforts at protocolizing care in an evidence-based fashion for this patient cohort.

BACKGROUND: Patients with complex congenital heart disease (CHD) are now commonly surviving well into adulthood. We describe the clinical characteristics and outcomes for a cohort of adult patients with moderate and great complexity CHD undergoing general surgery procedures. METHODS: The electronic records of two tertiary centers were queried to identify adult patients with moderate and great complexity CHD who underwent a general surgery procedure between 2007 and 2017. RESULTS: 118 adult patients were included in the analysis. The mean age was 36 ± 17 years and 49.2% were male. The most common cardiac diagnoses were pulmonary valve anomaly (24.6%), tetralogy of Fallot (18.6%), coarctation of the aorta (15.3%) and common/single ventricle (10.2%). The most common general surgery procedures performed were cholecystectomy (23.7%), herniorrhaphy (23.7%) and colorectal resection (9.3%). In-hospital mortality and morbidity were 2.5% and 11.9%, respectively. CONCLUSION: Adults survivors of moderate and great complexity CHD undergoing common general surgery procedures in this study experienced excellent in-hospital outcomes.

Background: The specificity and sensitivity of the (13)-ß-d-glucan (BDG) assay in surgical patients needs further investigation. We hypothesized that the BDG assay would have lower sensitivity/specificity compared with that of medical patients. Methods: We reviewed patients who had undergone laparotomy, gastrectomy, hepatectomy, or colectomy and had a BDG assay post-operatively. Results: A total of 71 patients met study criteria. There were 29 (40.8%) who had proven/probable invasive fungal infection. Sensitivity for BDG level ≥80 diagnosed within one week of the assay draw was 77.3% (95% confidence interval [CI], 54.6-92.2%), and specificity was 44.9% (95% CI, 30.7-59.8). The positive predictive value was 38.6% (95% CI, 31.0-46.9%), and negative predictive value was 82.5% (95% CI, 65.7-91.0%). A BDG assay result of 149 pg/mL had a classification rate of 63.4%. Therefore, a BDG assay result ≥150 pg/mL has a sensitivity of 78.6% and a specificity of 41.4%. Conclusion: A BDG assay can be useful for ruling out invasive fungemia in post-operative patients.
