RESUMO
BACKGROUND: Patients with chronic limb threatening ischemia may require a transmetatarsal amputation (TMA) or a transtibial amputation. When making an amputation-level decision, these patients face a tradeoff-a TMA preserves more limb and may provide better mobility but has a lower probability of primary wound healing and may therefore result in additional same or higher level amputation surgeries with an associated negative impact on function. Understanding differences in how patients and providers prioritize these tradeoffs and other outcomes may enhance shared decision-making. OBJECTIVES: Compare patient priorities with provider perceptions of patient priorities using Multiple Criteria Decision Analysis (MCDA). METHODS: The MCDA Analytic Hierarchy Process was chosen due to its low cognitive burden and ease of implementation. We included 5 criteria (outcomes): ability to walk, healing after amputation surgery, rehabilitation program intensity, limb length, and ease of use of prosthetic/orthotic device. A national sample of dysvascular lower-limb amputees and providers were recruited from the Veterans Health Administration with the MCDA administered online to providers and telephonically to patients. RESULTS: Twenty-six dysvascular amputees and 38 providers participated. Fifty percent of patients had undergone a TMA; 50%, a transtibial amputation. When compared to providers, patients placed higher value on TMA (72% vs. 63%). Patient versus provider priorities were ability to walk (47% vs. 42%), healing (18% vs. 28%), ease of prosthesis use (17% vs. 13%), limb length (11% vs. 13%), and then rehabilitation intensity (7% vs. 6%). LIMITATIONS: Our sample may not generalize to other populations. CONCLUSIONS: Provider perceptions aligned with patient values on amputation level but varied around the importance of each outcome. IMPLICATIONS: These findings illuminate some differences between patients' values and provider perceptions of patient values, suggesting a role for shared decision-making. Embedding this MCDA framework into a future decision aid may facilitate these discussions.

BACKGROUND: Cumulative musculoskeletal stress during operative procedures can contribute to the development of chronic musculoskeletal injury among surgeons. This is a concern in laparoscopic specialties where trainees may incur greater risk by learning poor operative posture or technique early in training. This study conducted an initial investigation of the physical stress encountered during the conduct of foregut laparoscopic surgery. METHODS: Subjects were divided into two groups based on their surgical experience level, high experience (HE), consisting of two attending surgeons, and low experience (LE), consisting of two fellow surgeons and a surgical chief resident. Nine distinct foregut laparoscopic procedures were observed for data collection within these groups. Electromyographic (EMG) activity was collected at the bilateral neck, shoulders, biceps, triceps, and lower back for each procedure. Physical workload was measured using percent reference voluntary contractions (%RVC) for each surgeon's muscle activities. Fatigue development was assessed using the median frequency of EMG data between two consecutive cases. Subjects completed a NASA-TLX survey when surgery concluded. RESULTS: LE surgeons experienced higher levels of %RVC in the lower back muscles compared to HE surgeons. LE fatigue level was also higher than HE surgeons across most muscle groups. A decrease in median frequency in six of the ten muscle groups after performing two consecutive cases, the largest decrements being in the biceps and triceps indicated fatigue development across consecutive cases for both surgeon groups. CONCLUSION: Surgeons developed fatigue in consecutive cases while performing minimally invasive surgery (MIS). HE surgeons demonstrated a lower overall physical workload while also demonstrating different patterns in muscle work. The findings from this study can be used to inform further ergonomic studies and the data from this study can be used to develop surgical training programs focused on the importance of surgeon ergonomics and minimizing occupational injury risk.

As part of a medicinal chemistry program aimed at developing a leukotriene C4 synthase inhibitor for the treatment of asthma, two tritium-labeled and one stable isotope-labeled compounds were required. The synthesis of the tritium-labeled compounds used a standard bromination-tritiodehalogentation approach. One of the tritium-labeled compounds was observed to exchange its tritium label slowly with the solvent. The stable isotope-labeled compound was prepared in seven steps (3% overall yield) from [2 H6 ]acetone in a modification of the route used by medicinal chemistry.

Nanoparticle assemblies have generated intense interest because of their novel optical, electronic, and magnetic properties that open up numerous opportunities in fundamental and applied nanophotonics, -electronics, and -magnetics. However, despite the great scientific and technological potential of these structures, it remains an outstanding challenge to reliably fabricate such assemblies with both nanometer-level structural control and precise spatial arrangements on a macroscopic scale. It is the combination of these two features that is key to realizing nanoparticle assemblies' potential, particular for device applications. To address this challenge, we propose a hierarchical assembly approach consisting of both template-particle and particle-particle interactions, whereby the former ensures precise addressability of assemblies on a surface and the latter provides nanometer-level structural control. Template-particle interactions are harnessed via chemical-pattern-directed assembly, and the particle-particle interactions are controlled using DNA-directed self-assembly. To demonstrate the potential of this hierarchical assembly approach, we demonstrate the fabrication of a particularly fascinating assembly: the nanoparticle heterodimer, which possesses a surprisingly rich set of plasmonic properties and is a promising candidate to enable a variety of imaging and sensing applications. Each heterodimer is placed on the surface at predetermined locations, and the precise control of the nanogaps is confirmed by far-field scattering measurements of individual dimers. We further demonstrate that the gap size can be effectively tuned by varying the DNA length. By correlating measured spectra with finite-difference time-domain (FDTD) simulations, we determine the gap sizes to be 4.2 and 5.0 nm-with subnm deviation-for the two DNA lengths investigated. This is one of the best gap uniformities ever demonstrated for surface-bound nanoparticle assemblies. The estimated surface-enhanced Raman scattering (SERS) enhancement factor of these heterodimers is on the order of 105-106 with high reproducibility and predictable polarization-dependence. This hierarchical fabrication technique-employing both template-particle and particle-particle interactions-constitutes a novel platform for the realization of functional nanoparticle assemblies on surfaces and thereby creates new opportunities to implement these structures in a variety of applications.
RESUMO
BACKGROUND: Early-stage esophageal cancer (stages 0-1) has been shown to have relatively good outcomes after local endoscopic or surgical resection. For this reason, neoadjuvant chemoradiation usually is reserved for higher-stage disease. Some early tumors, however, are found after resection to be more advanced than predicted based on initial clinical staging, termed pathologic upstaging. Such tumors may have benefited from alternate treatment models had their true stage been known preoperatively. This study aimed to identify high-risk features in early esophageal cancers that might predict tumor upstaging and guide more individualized treatment algorithms. METHODS: Through retrospective review of a single-institution foregut disease registry, we evaluated patients who underwent esophagectomy for high-grade dysplasia (Tis) or stage 1 esophageal cancer, searching for factors associated with pathologic upstaging. RESULTS: The review included 110 patients (88% male, median age at diagnosis, 64.5 years) treated between January 2000 and June 2016. Upstaging occurred for 20.9% of the patients, and was more common for patients with angiolymphatic invasion (odds ratio [OR], 11.07; 95% confidence interval [CI], 2.96-41.44; P < 0.001) or signet-ring features (OR, 23.9; 95% CI, 2.6-216.8; P = 0.005). In the absence of other predictors, upstaging was associated with decreased overall survival (P = 0.006). CONCLUSIONS: Approximately 20% of patients with early-stage esophageal cancer may be upstaged at resection. Angiolymphatic invasion and signet-ring features may predict tumors likely to be upstaged, resulting in decreased overall survival.

BACKGROUND: The role of primary tumor resection (PTR) for asymptomatic stage IV colon cancer with unresectable metastases remains unclear. Increasingly there has been a trend away from resection. The aim of this study was to examine trends in the treatment of stage IV colon cancers, impact of different treatments on long-term mortality, and factors associated with receipt of postoperative chemotherapy. METHODS: The 2006-2012 National Cancer Data Base was queried for stage IV colon cancer patients. Treatments were grouped into PTR and chemotherapy, PTR only, chemotherapy only, and no treatment. A descriptive analysis was performed examining patient and hospital characteristics associated with different treatments. A Cox regression analysis was used to assess the adjusted effect of different treatments on long-term survival. A multivariable logistic regression was used to examine factors associated with postoperative chemotherapy. RESULTS: Of 31,310 patients, who met inclusion criteria, 22% of the patients underwent PTR and chemotherapy, 37.5% received chemotherapy only, 11.9% underwent PTR, and 28.6% received no treatment. Patients who received no treatment had the highest hazard of death at 1, 3, and 5 y, followed by PTR only, and chemotherapy only compared with PTR combined with chemotherapy. Patients who were older and had more comorbidities were less likely to receive postoperative chemotherapy. CONCLUSIONS: Primary tumor resection in conjunction with postoperative chemotherapy among stage IV colon cancer patients with unresectable metastases was associated with a long-term survival benefit compared with other treatment options. Efforts should be made to increase the use of postoperative chemotherapy where feasible.

The efficacy with which solvent vapor annealing (SVA) can control block copolymer self-assembly has so far been demonstrated primarily for the simplest class of copolymer, the linear diblock copolymer. Adding a third distinct block-thereby creating a triblock terpolymer-not only provides convenient access to complex continuous network morphologies, particularly the gyroid phases, but also opens up a route toward the fabrication of novel nanoscale devices such as optical metamaterials. Such applications, however, require the generation of well-ordered 3D continuous networks, which in turn requires a detailed understanding of the SVA process in terpolymer network morphologies. Here, in situ grazing-incidence small-angle X-ray scattering (GISAXS) is employed to study the self-assembly of a gyroid-forming triblock terpolymer during SVA, revealing the effects of several key SVA parameters on the morphology, lateral order, and, in particular, its preservation in the dried film. The robustness of the terpolymer gyroid morphology is a key requirement for successful SVA, allowing the exploration of annealing parameters which may enable the generation of films with long-range order, e.g., for optical metamaterial applications.
RESUMO
Although Streptococcus pneumoniae is usually found as a commensal in healthy individuals, it can act as a pathogen in trauma patients, causing such complications as early-onset pneumonia and sepsis. We discovered that treating mice with an A-class CpG-oligodeoxynucleotide (ODN) at 2 h after traumatic injury significantly improved mouse survival following early-onset secondary lung infection with S. pneumoniae. This study used mass cytometry (cytometry by time-of-flight) and Luminex technologies to characterize the cellular immune response to secondary S. pneumoniae lung infection at 1 and 3 d postinfection. We found increased expression of CD14, CD64, and PD-L1 on F4-80(+) and F4-80(+)CD11c(+) macrophages, CD11c(+) dendritic cells, and CD14(+)CD172a(+) cells after burn-injury and infection, supporting previous reports of innate immune cell activation in sepsis. CpG-ODN treatment at 2 h after burn-injury reversed these effects; improved pathogen clearance; and led to an increased expression of CD25, CD27, MHCII, and IL-17 on or in TCRγδ cells at 1 d postinfection. At 3 d postinfection, CpG-ODN treatment increased the expression of PD-L1 on innate cell subsets. Furthermore, we analyzed cytokine levels in lung-washout samples of TCRγδ cell-depleted (TCRγδ(-)) mice to demonstrate that the effects of CpG-ODN on cytokine expression after burn-injury and S. pneumoniae infection rely on functional TCRγδ cells. In summary, we demonstrate that cytometry by time-of-flight provides an effective strategy to systematically identify specific cellular phenotypic responses to trauma and bacterial pneumonia and to discover changes in immune system phenotypes associated with beneficial immunotherapy.

OBJECTIVE: Trauma induces a complex immune response that requires a systems biology research approach. Here, we used a novel technology, mass cytometry by time-of-flight, to comprehensively characterize the multicellular response to trauma. DESIGN: Peripheral blood mononuclear cells samples were stained with a 38-marker immunophenotyping cytometry by time-of-flight panel. Separately, matched peripheral blood mononuclear cells were stimulated in vitro with heat-killed Streptococcus pneumoniae or CD3/CD28 antibodies and stained with a 38-marker cytokine panel. Monocytes were studied for phagocytosis and oxidative burst. SETTING: Single-institution level 1 trauma center. PATIENTS OR SUBJECTS: Trauma patients with injury severity scores greater than 20 (n = 10) at days 1, 3, and 5 after injury, and age- and gender-matched controls. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Trauma-induced expansion of Th17-type CD4 T cells was seen with increased expression of interleukin-17 and interleukin-22 by day 5 after injury. Natural killer cells showed reduced T-bet expression at day 1 with an associated decrease in tumor necrosis factor-ß, interferon-γ, and monocyte chemoattractant protein-1. Monocytes showed robust expansion following trauma but displayed decreased stimulated proinflammatory cytokine production and significantly reduced human leukocyte antigen - antigen D related expression. Further analysis of trauma-induced monocytes indicated that phagocytosis was no different from controls. However, monocyte oxidative burst after stimulation increased significantly after injury. CONCLUSIONS: Using cytometry by time-of-flight, we were able to identify several major time-dependent phenotypic changes in blood immune cell subsets that occur following trauma, including induction of Th17-type CD4 T cells, reduced T-bet expression by natural killer cells, and expansion of blood monocytes with less proinflammatory cytokine response to bacterial stimulation and less human leukocyte antigen - antigen D related. We hypothesized that monocyte function might be suppressed after injury. However, monocyte phagocytosis was normal and oxidative burst was augmented, suggesting that their innate antimicrobial functions were preserved. Future studies will better characterize the cell subsets identified as being significantly altered by trauma using cytometry by time-of-flight, RNAseq technology, and functional studies.

OBJECTIVES: To determine if patients managed with a cystectomy enhanced recovery pathway (CERP) have improved quality of care after radical cystectomy (RC), as defined by a decrease in length of hospital stay (LOS) without an increase in complications or readmissions compared with those not managed with CERP. SUBJECTS AND METHODS: The Quality Improvement in Cystectomy Care with Enhanced Recovery (QUICCER) study was a non-randomized quasi-experimental study. Data were collected between June 2011 and April 2015. The CERP was implemented in July 2013. The primary endpoint was LOS. Secondary endpoints were quality scores, complications and readmissions. Multivariable regression was performed. Propensity score matching was carried out to further simulate randomized clinical trial conditions. A CERP quality composite score was created and evaluated with regard to adherence to CERP elements. RESULTS: The study included 79 patients managed with CERP and 121 who were not managed with CERP. After matching, there were 75 patients in the non-CERP group. The LOS was significantly different between the groups: the median LOS was 5 and 8 days for the CERP and non-CERP group, respectively (P < 0.001). Multivariable linear regression showed that any complication was the most significant predictor of total LOS at 90 days after RC. The higher the quality composite score the shorter the LOS (P < 0.001). There was no association between CERP and a greater number of complications or readmissions. CONCLUSIONS: Audited quality measures in the CERP are associated with a reduction in LOS with no increase in readmissions or complications. The CERP is important for the future improvement of peri-operative care for RC and provides an opportunity to improve the quality of care provided.

BACKGROUND AND OBJECTIVES: Gastric ischemic preconditioning has been proposed to improve blood flow and reduce the incidence of anastomotic complications following esophagectomy with gastric pull-up. This study aimed to evaluate the effect of prolonged ischemic preconditioning on the degree of neovascularization in the distal gastric conduit at the time of esophagectomy. METHODS: A retrospective review of a prospectively maintained database identified 30 patients who underwent esophagectomy. The patients were divided into three groups: control (no preconditioning, n = 9), partial (short gastric vessel ligation only, n = 8), and complete ischemic preconditioning (left and short gastric vessel ligation, n = 13). Microvessel counts were assessed, using immunohistologic analysis to determine the degree of neovascularization at the distal gastric margin. RESULTS: The groups did not differ in age, gender, BMI, pathologic stage, or cancer subtype. Ischemic preconditioning durations were 163 ± 156 days for partial ischemic preconditioning, compared to 95 ± 50 days for complete ischemic preconditioning (P = 0.2). Immunohistologic analysis demonstrated an increase in microvessel counts of 29% following partial ischemic preconditioning (P = 0.3) and 67% after complete ischemic preconditioning (P < 0.0001), compared to controls. CONCLUSIONS: Our study indicates that prolonged ischemic preconditioning is safe and does not interfere with subsequent esophagectomy. Complete ischemic preconditioning increased neovascularization in the distal gastric conduit.

Few studies have examined the relationship between basic psychological needs (BPN), depression and quality of life (QOL) in people living with HIV (PLWH). This cross-sectional study (N = 65; 37% females, 37% Caucasian, mean age = 55 ± 6 years, mean CD4 count = 668 ± 368â cells/mm3, average duration of HIV = 18 ± 4 years) found that BPN frustration was related with lower QOL. The strength of this relationship was reduced after controlling for depression. This suggests that depression partially mediated the relationship between BPN and QOL. BPN and depression may be specific targets for psychosocial interventions aimed at improving QOL in PLWH to promote successful aging.

BACKGROUND: The treatment of early-stage esophageal cancer and high-grade dysplasia of the esophagus has changed significantly in recent years. Many early tumors that were traditionally treated with esophagectomy can now be resected with endoscopic therapy alone. These new endoscopic modalities can offer similar survival outcomes without the associated morbidity of a major operation. However, a number of these cases may still require surgical intervention as the best treatment option. METHODS: The current scientific literature, national and international guidelines were reviewed for recommendations regarding optimal treatment of early esophageal malignancy. RESULTS: The primary advantage of surgery over endoscopic treatment lies in the reduced risk of recurrence as well as the ability to assess harvested lymph nodes for regional disease. We recommend that esophageal tumors that have invaded into the submucosa (T1b) or beyond should be treated with an esophagectomy. In addition, dysplastic lesions and cancers that demonstrate poorly differentiated pathology or lymphovascular or perineural invasion should be surgically resected. Finally, large tumors, multifocal lesions, tumors within a long segment of Barrett's esophagus, tumors adjacent to a hiatal hernia, tumors that cannot be resected enbloc with endoscopic techniques should also be treated with an esophagectomy. CONCLUSIONS: When performed at high-volume centers in experienced hands, esophagectomy can have consistently good outcomes for high-grade dysplasia and early esophageal cancers, and should be considered as a treatment option.

PURPOSE: Hiatal hernias are a common finding on radiographic or endoscopic studies. Hiatal hernias may become symptomatic or, less frequently, can incarcerate or become a volvulus leading to organ ischemia. This review examines latest evidence on the diagnostic workup and management of hiatal hernias. METHODS: A literature review of contemporary and latest studies with highest quality of evidence was completed. This information was examined and compiled in review format. RESULTS: Asymptomatic hiatal and paraesophageal hernias become symptomatic and necessitate repair at a rate of 1% per year. Watchful waiting is appropriate for asymptomatic hernias. Symptomatic hiatal hernias and those with confirmed reflux disease require operative repair with an anti-reflux procedure. Key operative steps include the following: reduction and excision of hernia sac, 3 cm of intraabdominal esophageal length, crural closure with mesh reinforcement, and an anti-reflux procedure. Repairs not amenable to key steps may undergo gastropexy and gastrostomy placement as an alternative procedure. CONCLUSIONS: Hiatal hernias are commonly incidental findings. When hernias become symptomatic or have reflux disease, an operative repair is required. A minimally invasive approach is safe and has improved outcomes.

BACKGROUND & AIMS: Transoral esophagogastric fundoplication (TF) can decrease or eliminate features of gastroesophageal reflux disease (GERD) in some patients whose symptoms persist despite proton pump inhibitor (PPI) therapy. We performed a prospective, sham-controlled trial to determine if TF reduced troublesome regurgitation to a greater extent than PPIs in patients with GERD. METHODS: We screened 696 patients with troublesome regurgitation despite daily PPI use with 3 validated GERD-specific symptom scales, on and off PPIs. Those with at least troublesome regurgitation (based on the Montreal definition) on PPIs underwent barium swallow, esophagogastroduodenoscopy, 48-hour esophageal pH monitoring (off PPIs), and high-resolution esophageal manometry analyses. Patients with GERD and hiatal hernias ≤2 cm were randomly assigned to groups that underwent TF and then received 6 months of placebo (n = 87), or sham surgery and 6 months of once- or twice-daily omeprazole (controls, n = 42). Patients were blinded to therapy during follow-up period and reassessed at 2, 12, and 26 weeks. At 6 months, patients underwent 48-hour esophageal pH monitoring and esophagogastroduodenoscopy. RESULTS: By intention-to-treat analysis, TF eliminated troublesome regurgitation in a larger proportion of patients (67%) than PPIs (45%) (P = .023). A larger proportion of controls had no response at 3 months (36%) than subjects that received TF (11%; P = .004). Control of esophageal pH improved after TF (mean 9.3% before and 6.3% after; P < .001), but not after sham surgery (mean 8.6% before and 8.9% after). Subjects from both groups who completed the protocol had similar reductions in GERD symptom scores. Severe complications were rare (3 subjects receiving TF and 1 receiving the sham surgery). CONCLUSIONS: TF was an effective treatment for patients with GERD symptoms, particularly in those with persistent regurgitation despite PPI therapy, based on evaluation 6 months after the procedure. Clinicaltrials.gov no: NCT01136980.

BACKGROUND: The surgical care pathway is characterized by multiple transitions, from preoperative assessment to inpatient stay, discharge from hospital, and follow-up care. Breakdowns in one phase can affect subsequent phases, which in turn can cause delays, cancellations, and complications. Efforts to improve care transitions focused primarily on post-discharge care coordination and inpatient education for medically complex patients have not demonstrated consistent effects. This study aimed to understand the expectations and perceptions of postoperative inpatients regarding transition from hospital to home in an effort to reduce patient burden. MATERIALS AND METHODS: Patients who underwent a colorectal resection at a large academic medical center and were discharged home were eligible to participate in the study. Patients were recruited during their postoperative hospital stays and interviewed over the phone within a week after discharge about their perceptions of care, values, and attitudes. Overall, we recruited 16 patients with benign (n = 8) and malignant (n = 8) indications. Recruitment continued until theme saturation. RESULTS: Factors that shaped patients' understanding of postsurgical recovery and that motivated them to seek provider attention post-discharge fell into three major groups: patient expectations versus reality, availability and role of informal caregivers in the postoperative recovery process, and communication as a key to patient confidence and trust. CONCLUSIONS: For patients and caregivers, postoperative planning starts long before surgery and hospital admission. Providers should consider these dynamics in designing interventions to improve care transitions, patient satisfaction, and long-term outcomes. This study was limited to colorectal surgical patients treated in a single institution and may be not generalizable to other surgical procedures, non-academic settings or different regions.

BACKGROUND: Children with cancer suffer significant morbidity throughout therapy and often face an uncertain prognosis. Because palliative care teams can provide an additional layer of support with symptom management and communication, we conducted a prospective study assessing the feasibility of early palliative care consultation for children with high-risk malignancies. PROCEDURE: This study was part of a larger prospective study examining the impact of early palliative care consultation. Children were eligible if they were <22 years old and had a high-risk malignancy, recurrence, or required hematopoietic stem cell transplantation (HSCT). Data were collected from the medical record on diagnosis, days to consultation, acceptability of consultation to family/staff, and overall survival. Feasibility was defined as enrollment of >75% of eligible patients, palliative care consultation within 1 month of eligibility, and patient/family satisfaction. RESULTS: Twenty of 25 (80%) eligible patients were approached and received a palliative care consultation at initial diagnosis (7), recurrence (12), or time of HSCT (1). Median age of the children was 5 years (0.1-20 years). Median time from new diagnosis/recurrence to consultation was 12 days (2-180 days); 17 (85%) received the consultation within 30 days. Eleven (55%) of the 20 children died. Median time of consultation prior to death was 128 days (10-648 days). Ten of the 11 (91%) received their consultation >30 days prior to death. No families or oncologists declined an early consultation. CONCLUSIONS: Early palliative care consultation is feasible for children with high-risk cancer and is acceptable to children, families, and pediatric oncologists.

BACKGROUND: Bile duct injury (BDI) after laparoscopic cholecystectomy (LC) has significant cost impact and is a significant source of morbidity and mortality. We undertook a population-based assessment of the national experience with BDI between 2001 and 2011 and compared this to our report for the prior decade. METHODS: Using the nationwide inpatient sample (NIS) for 2001-2011, we identified patients who underwent LC or partial cholecystectomy, with and without biliary reconstruction. Data were analyzed using methods that accounted for the hierarchical, stratified random sampling of the NIS. Both univariate modeling and multivariate modeling were performed. RESULTS: LCs increased from 71.1 % in 2001 to 79.0 % in 2011 (p < 0.0001). Annual mortality decreased from 0.56 to 0.38 % (p = 0.002). In 2001, 0.11 % of LCs were associated with biliary reconstruction versus 0.09 % in 2011 (p = 0.15) with rates ranging from 0.08 to 0.12 %. The need for reconstruction was associated with an average in-hospital mortality rate of 4.4 %. Mortality rates from LC remained consistent across the study period (average mortality, 0.10 %, p = 0.57). Under multivariate analysis, admission to rural or urban non-teaching centers was associated with a decreased rate of injury; the majority of major BDIs were admitted from clinic or outpatient settings. These results are consistent with results from the prior decade. Neither emergent admission nor race was associated with increased odds of BDI, and this differs from our prior analysis. CONCLUSION: LC continued to increase in utilization between 2001 and 2011. Although rates of BDI have decreased, the need for reconstruction continues to be associated with a significant mortality. In addition, mortality related to biliary reconstruction is also higher than previously published series and may reflect the complexity of managing biliary injury as well as the higher likelihood of these patients having comorbid conditions.

INTRODUCTION: Esophageal cancer is the eighth most common cancer worldwide and the sixth leading cause of cancer-related deaths. As a significant cause of morbidity and mortality, its burden on society has yet to be fully characterized. The aim of this study is to examine its global burden through estimation of the disability-adjusted life years (DALYs) attributable to it. METHODS: Global incidence and mortality estimates for esophageal cancer were obtained from the International Agency for Research on Cancer GLOBOCAN 2008 database. DALYs were calculated, using methodology established by the World Health Organization. RESULTS: In 2008, 3,955,919 DALYs were attributed to esophageal cancer, at a global rate of 0.58 DALYs per 1000 people annually. Years of life lost (YLL) accounted for 96.8 % of DALYs, while years lived with disability (YLD) accounted for 3.2 %. 83.8 % of the global DALYs occurred in less-developed countries, with most accrued in Eastern Asia, comprising 50.9 % of the total. The highest rate of DALY accrual was in Southern Africa, at 1.62 DALYs per 1000 people annually. CONCLUSIONS: A substantial number of years of life were lost or affected by esophageal cancer worldwide in 2008, with the burden resting disproportionately on less-developed countries. Geographically, the greatest burden is in Eastern Asia. The vast majority of DALYs were due to YLL, rather than YLD, indicating the need to focus resources on disease prevention and early detection. Our findings provide an additional basis upon which to formulate global priorities for interventions that affect DALY reduction in esophageal cancer.
