ABSTRACT
OBJECTIVE: Despite regulatory challenges, device availability, and rapidly expanding techniques, off-label endovascular repair of complex aortic aneurysms (cAAs) has expanded in the past decade. Given the lack of United States Food and Drug Administration-approved endovascular technology to treat cAAs, we performed a national census to better understand volume and current practice patterns in the United States. METHODS: Targeted sampling identified vascular surgeons with experience in off-label endovascular repair of cAAs. An electronic survey was distributed with institutional review board approval from the University of Rochester to 261 individuals with a response rate of 38% (n = 98). RESULTS: A total of 93 respondents (95%) reported off-label endovascular repair of cAAs. Mean age was 45.7 ± 8.3 years, and 84% were male. Most respondents (59%) were within the first 10 years of practice, and 69% trained at institutions with a high-volume of off-label endovascular procedures for complex aortic aneurysms with or without a physician-sponsored investigational device exemption (PS-IDE). Twelve respondents from 11 institutions reported institutional PS-IDEs for physician-modified endografts (PMEGs), in-situ laser fenestration (ISLF), or parallel grafting technique (PGT), including sites with PS-IDEs for custom-manufactured devices. Eighty-nine unique institutions reported elective off-label endovascular repair with a mean of 20.2 ± 16.5 cases/year and â¼1757 total cases/year nationally. Eighty reported urgent/emergent off-label endovascular repair with a mean of 5.7 ± 5.4 cases/year and â¼499 total cases/year nationally. There was no correlation between high-volume endovascular institutions (>15 cases/year) and institutions with high volumes of open surgical repair for cAAs (>15 cases/year; odds ratio, 0.7; 95% confidence interval, 0.3-1.5; P = .34). Elective techniques included PMEG (70%), ISLF (30%), hybrid PMEG/ISLF (18%), and PGT (14%), with PMEG being the preferred technique for 63% of respondents. Techniques for emergent endovascular treatment of complex aortic disease included PMEG (52%), ISLF (40%), PGT (20%), and hybrid-PMEG/ISLF (14%), with PMEG being the preferred technique for 41% of respondents. Thirty-nine percent of respondents always or frequently offer referrals to institutions with PS-IDEs for custom-manufactured devices. The most common barrier for referral to PS-IDE centers included geographic distance (48%), longitudinal relationship with patient (45%), and costs associated with travel (33%). Only 61% of respondents participate in the Vascular Quality Initiative for complex endovascular aneurysm repair, and only 57% maintain a prospective institutional database. Eighty-six percent reported interest in a national collaborative database for off-label endovascular repair of cAA. CONCLUSIONS: Estimates of off-label endovascular repair of cAAs are likely underrepresented in the literature based on this national census. PMEG was the most common technique for elective and emergent procedures. Under-reported off-label endovascular repair of cAA outcomes data appears to be limited by non-standardized PS-IDE reporting to the United States Food and Drug Administration, and the lack of Vascular Quality Initiative participation and prospective institutional data collection. Most participants are interested in a national collaborative database for endovascular repair of cAAs.
ABSTRACT
BACKGROUND: While endovascular aneurysm repair has become a first-line strategy in many centers, open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) is still the best option for certain patients. A significant number of patients who are offered OSR for AAA have been previously submitted to other open abdominal surgeries (PAS). It is unclear, however, how this may impact their outcomes. The purpose of this study was to determine if there is an association between PAS and outcomes of OSR of AAA. METHODS: This is a retrospective cohort study based on clinical data from the American College of Surgeons National Surgical Quality Improvement Program database, including all patients undergoing elective OSR for AAA between 2011 and 2017. Excluded were patients with missing data on prior abdominal surgery, supramesenteric clamping, or urgent repairs. Patients with prior abdominal surgery (PAS) and patients without prior abdominal surgeries (nonPAS) were compared. The primary outcome was 30-day postoperative mortality. Secondary outcomes were operating time, ischemic colitis, postoperative complications, and lengths of hospital stay. RESULTS: Of the 2034 patients included, 27% had previous open abdominal surgery and 73% did not. Overall, the median age was 71(interquartile range 65-76), 72% of patients were male, 44% were smokers, and the average body mass index was 27 kg/m2. Univariate analysis showed no difference in postoperative 30-day mortality (4.0% PAS vs. 4.1% nonPAS, P = 0.91) or overall postoperative complication rates (33% PAS vs. 29% nonPAS, P = 0.07). Previous open abdominal surgery was significantly associated with longer operating times (P = 0.032) and an almost doubled rate of ischemic colitis (4.7% PAS vs. 2.6% nonPAS, P = 0.02). Postoperative intensive care unit and hospitalization were also significantly longer in patients with prior abdominal surgery (P = 0.005 and P = 0.014, respectively). Finally, there were significantly less patients discharged home, as opposed to institutionalized care (75.7% PAS down from 82.4% nonPAS, P = 0.001). Despite these initial univariate analysis results, on multivariate analysis, PAS actually did not prove to be a statistically significant independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. CONCLUSIONS: This study suggests that patients who have undergone PAS may have some disadvantages in OSR of AAA. However, these negative trends do not go so far as to statistically significantly identify PAS as an independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. As such, we suggest that a history of previous open abdominal surgery, in and of its own, should not exclude patients from consideration for open aortic abdominal aneurysm repair.

BACKGROUND: Patients with chronic limb-threatening ischemia (CLTI) and chronic kidney disease (CKD) are at risk of developing renal injury following revascularization. We aimed to compare the risk of adverse renal events following endovascular revascularization (ER) or open surgery (OS) in patients with CLTI and CKD. METHODS: A retrospective analysis of the National Surgical Quality Improvement Program (NSQIP) databases (2011-2017) was performed including patients with CLTI and non-dialysis-dependent CKD, comparing ER to OS. The primary outcome was a composite of postprocedural kidney injury or failure within 30 days. Thirty-day mortality, major adverse cardiac and cerebrovascular events (MACCE), amputation, readmission or target lesion revascularization (TLR) were compared using multivariate logistic regression and propensity-score matched analysis. RESULTS: A total of 5009 patients were included (ER: 2361; OS: 3409). The risk for the composite primary outcome was comparable between groups (odds ratio [OR]: 0.78, 95% confidence interval (CI): 0.53-1.17) as for kidney injury (n=54, OR: 0.97, 95% CI: 0.39-1.19) or failure (n=55, OR: 0.68, 95% CI: 0.39-1.19). In the adjusted regression, a significant benefit was observed with ER for the primary outcome (OR: 0.60, p=0.018) and renal failure (OR: 0.50, p=0.025), but not for renal injury (OR: 0.76, p=0.34). Lower rates of MACCE, TLR, and readmissions were observed after ER. Thirty-day mortality and major amputation rates did not differ. In the propensity score analysis, revascularization strategy was not associated with renal injury or failure. CONCLUSIONS: In this cohort, the incidence of renal events within 30 days of revascularization in CLTI was low and comparable between ER and OR. CLINICAL IMPACT: In a cohort of 5009 patients with chronic limb-threatening ischemia and non-end-stage chronic kidney disease (CKD), postprocedural kidney injury or failure within 30 days was comparable between patients submitted to open or endovascular revascularization (ER). Lower rates of major adverse cardiac and cerebrovascular events, target lesion revascularization, and readmissions were observed after endovascular revascularization. Based on these findings, ER should not be avoided due to fear of worsening renal function in CKD patients with chronic limb-threatening ischemia. In fact, these patients benefit more from ER regarding cardiovascular outcomes with no increased risk of kidney injury.
ABSTRACT
We describe the case of a patient with an ascending aortic aneurysm who underwent valve-in-valve transcatheter aortic valve implantation, which was complicated by valve embolization. After a multidisciplinary discussion and an innovative approach, the free-floating embolized valve was anchored securely in the aortic arch with an uncovered aortic endovascular stent. (Level of Difficulty: Intermediate.).
ABSTRACT
BACKGROUND: The increasing proportion of elderly patients being treated for abdominal aortic aneurysm (AAA) in the endovascular era is controversial. OBJECTIVES: This study compared 30-day outcomes of endovascular aortic repair (EVAR) in nonagenarians (NAs) with non-nonagenarians (NNAs). METHODS: This retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database included EVAR procedures performed from 2011 to 2017. Multivariate logistic regression in the unadjusted cohort, followed by propensity-score matching (PSM), was performed. Primary outcomes were 30-day mortality and 30-day major adverse events. RESULTS: A total of 12,267 patients were included (365 NAs). Ruptured aneurysms accounted for 6.7% (n = 819): 15.7% (n = 57) in NAs versus 6.5% (n = 762) in NNAs (p < 0.001). Mean aneurysm diameter was 6.5 ± 1.8 cm in NAs versus 5.8 ± 1.7 cm in NNAs (p < 0.001). The unadjusted 30-day mortality was 9.9% in NA versus 2.2% in NNAs (p < 0.001). Multivariate analysis revealed age ≥90 years (odds ratio [OR]: 3.36), male sex (OR: 1.78), functional status (OR: 4.22), pre-operative ventilator dependency (OR: 3.80), bleeding disorders (OR: 1.52), dialysis (OR: 2.56), and ruptured aneurysms (OR: 17.21) as independent predictors of mortality. After PSM, no differences in 30-day mortality (intact AAA [iAAA]: 5.3% NA vs. 3% NNA [p = 0.15]; ruptured AAA [rAAA]: 38% NA vs. 28.6% NNA [p = 0.32]) or 30-day major adverse events (iAAA: 7% NA vs. 4.6% NNA [p = 0.22]; rAAA: 28% NA vs. 36.7% NNA [p = 0.35]) were observed. CONCLUSIONS: Age was identified as an independent predictor of 30-day mortality after EVAR on multivariate analysis. However, no differences were found after PSM, suggesting that being ≥90 years of age but with similar comorbidities to younger patients is not associated with a higher short-term mortality after EVAR. Age ≥90 years alone should not exclude patients from EVAR, and tailored indications and carefully balanced risk assessment are advised.

BACKGROUND: Chronic limb-threatening ischemia (CLTI), defined as ischemic rest pain or tissue loss secondary to arterial insufficiency, is caused by multilevel arterial disease with frequent, severe infrageniculate disease. The rise in CLTI is in part the result of increasing worldwide prevalence of diabetes, renal insufficiency, and advanced aging of the population. The aim of this study was to compare a bypass-first with an endovascular-first revascularization strategy in patients with CLTI due to infrageniculate arterial disease. METHODS: We reviewed the American College of Surgeons National Surgical Quality Improvement Program targeted lower extremity revascularization database from 2012 to 2015 to identify patients with CLTI and isolated infrageniculate arterial disease who underwent primary infrageniculate bypass or endovascular intervention. We excluded patients with a history of ipsilateral revascularization and proximal interventions. The end points were major adverse limb event (MALE), major adverse cardiovascular event (MACE), amputation at 30 days, reintervention, patency, and mortality. Multivariable logistic regression was used to determine the association of a bypass-first or an endovascular-first intervention with outcomes. RESULTS: There were 1355 CLTI patients undergoing first-time revascularization to the infrageniculate arteries (821 endovascular-first revascularizations and 534 bypass-first revascularizations) identified. There was no significant difference in adjusted rate of 30-day MALE in the bypass-first vs endovascular-first revascularization cohort (9% vs 11.2%; odds ratio [OR], 0.73; 95% confidence interval [CI], 0.50-1.08). However, the incidence of transtibial or proximal amputation was lower in the bypass-first cohort (4.3% vs 7.4%; OR, 0.60; CI, 0.36-0.98). Patients with bypass-first revascularization had higher wound complication rates (9.7% vs 3.7%; OR, 2.75; CI, 1.71-4.42) compared with patients in the endovascular-first cohort. Compared with the endovascular-first cohort, the incidence of 30-day MACE was significantly higher in bypass-first patients (6.9% vs 2.6%; adjusted OR, 3.88; CI, 2.18-6.88), and 30-day mortality rates were 3.23% vs 1.8% (adjusted OR, 2.77; CI, 1.26-6.11). There was no difference in 30-day untreated loss of patency, reintervention of treated arterial segment, readmissions, and reoperations between the two cohorts. In subgroup analysis after exclusion of dialysis patients, there was also no significant difference in MALE or amputation between the bypass-first and endovascular-first cohorts. CONCLUSIONS: CLTI patients with isolated infrageniculate arterial disease treated by a bypass-first approach have a significantly lower 30-day amputation. However, this benefit was not observed when dialysis patients were excluded. The bypass-first cohort had a higher incidence of MACE compared with an endovascular-first strategy. These results reaffirm the need for randomized controlled trials, such as the Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL-2) trial and Best Endovascular vs Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI), to provide level 1 evidence for the role of endovascular-first vs bypass-first revascularization strategies in the treatment of this population of challenging patients.

INTRODUCTION: Our aim was to compare the effect of techniques of wound closure in the emergent colon surgery with wound class IV. METHODS: Using 2014 the colectomy targeted ACS-NSQIP dataset; we identified patients undergoing emergent colectomy with wound class IV. Comparison of surgical incision complete closure versus leaving the skin open and multivariate logistic regression analyses was performed. RESULTS: Of 1792 patients undergoing emergent colectomy with wound class IV, the complete closure cohort had 1376 patients and the incision skin open cohort had 416 patients. The incidence of deep SSI was 2.3% in the complete closure cohort vs. 1.2% in the incision skin open, p = 0.15, and intra-abdominal abscess rate was 11.8% in the complete closure cohort vs. 12.3% in the incision skin open, p = 0.78. The dehiscence rate, readmission rate, and reoperation rates were not statistically significant between two cohorts. A multivariate model for dehiscence did not yield significant association between the complete closure cohort and incision skin open cohort. CONCLUSIONS: Surgical incision complete wound closure in the emergent colon surgery with wound class III/IV is safe and effective.

BACKGROUND: Treatment reality of abdominal aortic aneurysm (AAA) is changing. Up to date, approximately 65% of intact AAA and 30% of ruptured AAA are treated endovascularly. As most comparative studies focus upon mortality and few major complications, some outcomes as lower extremity ischemia (LEI) after invasive AAA repair are often underreported. However, there is evidence for a worse outcome of patients suffering from this kind of complication. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) vascular surgery targeted module from 2011 to 2014, we identified all patients undergoing endovascular aortic repair (EVAR) and open aortic repair (OAR) for AAA to illuminate the incidence and outcome of LEI after AAA repair. RESULTS: In total, 185 patients (1.9%) developed LEI after AAA repair. 1.6% of all patients showed LEI after treatment of asymptomatic or symptomatic intact AAA, compared with 4.8% of ruptured AAA repair (P < 0.001). Operation time, male gender, current smoking, and increased creatinine levels (>1.5 mg/dL) were associated with an increased likelihood of exhibiting LEI. No statistically significant differences between EVAR versus OAR were noted in the multivariate model. If LEI occurred, length of hospital stay (6 vs. 2 days, P < 0.001) and mortality (20.5 vs. 4.6%, P < 0.001) was significantly higher as compared with the patients without LEI. Furthermore, 30-day mortality and most major complications were more common if LEI occurred. CONCLUSIONS: In this specialized analysis regarding LEI after AAA repair up to 2% develop this severe ischemic complication. Since the occurrence of LEI is associated with significantly worse outcome, future research and strategies to avoid this complication is needed.

INTRODUCTION: The management of patients with abdominal aortic injury (AAI) remains challenging. Open repair of AAI is still the standard of care although it is associated with high mortality. In past few years, endovascular surgery has evolved as a less invasive alternative to open surgery in emergency settings. The objective of this study was to compare outcomes after open repair versus endovascular repair of AAI in polytrauma patients. METHODS: The National Trauma Data Bank, from 2008 to 2012, was queried to identify trauma patients undergoing open and endovascular repair of AAI using International Classification of Diseases, ninth Edition, and Clinical Modification codes. Data reviewed included demographics, type of associated injury, type of operative management, and complications. Factors independently associated with mortality were evaluated using multivariate logistic regression model. RESULTS: Of 325 injured patients with AAI, 91 patients underwent endovascular repair and 234 patients underwent open repair. Of these, 80.6% were male, with a mean age of 35.70 years, and a mean injury severity score (ISS) was 30.59 for patients undergoing open repair and 31.56 for endovascular repair. Associated traumatic injuries included bowel injuries 57.5%, liver-pancreas injuries 36.6%, splenic injuries 14.8%, renal injuries 15.7%, and retroperitoneal injuries 19.1%. In-patient mortality for patients undergoing the open repair cohort was 63.7% and 20.9% for patients in the endovascular cohort (P < 0.001). The endovascular repair cohort patients had a higher incidence of pneumonia 17.6% as compared to open repair cohort 5.1% (P < 0.001). Similarly, patients in the endovascular repair cohort also had a higher abdominal compartment syndrome (4.4% vs. 0.4% in the open repair cohort, P = 0.009), postoperative acute kidney injury (9.9% endovascular repair cohort vs. 6.4% in the open repair cohort, P = 0.281), and acute mesenteric ischemia (1.1%). After controlling for associated injuries, acidosis, blood pressure at presentation, age, and ISS, patients in the open repair cohort had 6.58 times higher odds (confidence interval: 3.25-13.33; P < 0.001) of mortality as compared to the endovascular repair cohort. CONCLUSIONS: Endovascular repair of abdominal aorta in polytrauma patients seems to be feasible and may improve survivorship in appropriately selected patients. More research is needed to understand to identify indications for endovascular repair versus open repair.

OBJECTIVE: Our institution began Advanced Trauma Operative Management (ATOM) simulation course in 2007 for senior residents with the aim of increasing opportunities for surgical trainees to gain operative trauma experience. The aim of our study was to evaluate the effect of the ATOM simulation course on residents' choice of trauma as a career as demonstrated by entrance into surgical critical care (SCC) fellowships. DESIGN: Retrospective study of institutional data on graduating residents from 2002 to 2015. Residents were divided into pre-ATOM (2002-08) and post- (institution of) ATOM (2009-15) cohorts. The percentage of residents entering SCC fellowships was then compared among cohorts as well as to national trends. RESULTS: Nationally the pre-ATOM group had 7057 graduating general surgery (GS) residents (847 SCC) and post-ATOM had 7581 graduating GS residents (1268 SCC). Locally the pre-ATOM group consisted of 40 graduating GS residents (1 SCC) and while the post-ATOM cohort had 51 graduating GS residents (9 SCC). The number of SCC fellows increased by 4.7% nationally and 15.7% institutionally between the two study groups. The increased interest in SCC was more than could be accounted for by national trends. CONCLUSIONS: Interest in a career in trauma was increased among residents graduating from this single institution after instituting ATOM as part of the educational curriculum.

The Advanced Trauma Operative Management (ATOM) course is a simulation course adopted by the American College of Surgeons to teach operative management of primarily penetrating, traumatic injuries. Although it is clear that overall operative trauma exposure is decreasing, the educational benefit of ATOM for residents with different amounts of trauma exposure remains unclear. Our aim was to determine whether residents from trauma centers experienced less benefit from the ATOM course when compared with residents from nontrauma centers. We compared two groups of residents who take ATOM through our institutional course, those from trauma centers and those from nontrauma centers. ATOM pre- and postcourse evaluations of knowledge and self-efficacy were collected from October 2007 to June 2013. Overall residents from three institutions, two trauma centers (100 residents) and one nontrauma center (34 residents), were included in the study. All resident groups had statistically significant improvement in knowledge and self-efficacy after taking the ATOM course (P < 0.0001). There was no statistically significant difference in improvement relative to each of the groups in the ATOM categories of knowledge and self-efficacy. Our data show that residents with different levels of trauma exposure had similar pre- and postcourse scores as well as improvement in the ATOM evaluations. As operative trauma continues to decrease the ATOM course shows benefit for all residents regardless of the depth of their clinical trauma exposure in surgical residency.

INTRODUCTION: Frailty is a clinical state of increased vulnerability resulting from aging-associated decline in physiologic reserve. Hip fractures are serious fall injuries that affect our aging population. We retrospectively sought to study the effect of frailty on postoperative outcomes after Total Hip Arthroplasty (THA) and Hemiarthroplasty (HA) for femoral neck fracture in a national data set. METHODS: National Surgical Quality Improvement Project dataset (NSQIP) was queried to identify THA and HA for a primary diagnosis femoral neck fracture using ICD-9 codes. Frailty was assessed using the modified frailty index (mFI) derived from the Canadian Study of Health and Aging. The primary outcome was 30-day mortality and secondary outcomes were 30-day morbidity and failure to rescue (FTR). We used multivariate logistic regression to estimate odds ratio for outcomes while controlling for confounders. RESULTS: Of 3121 patients, mean age of patients was 77.34 ± 9.8 years. The overall 30-day mortality was 6.4% (3.2%-THA and 7.2%-HA). One or more severe complications (Clavien-Dindo class-IV) occurred in 7.1% patients (6.7%-THA vs.7.2%-HA). Adjusted odds ratios (ORs) for mortality in the group with the higher than median frailty score were 2 (95%CI, 1.4-3.7) after HA and 3.9 (95%CI, 1.3-11.1) after THA. Similarly, in separate multivariate analysis for Clavien-Dindo Class-IV complications and failure to rescue 1.6 times (CI95% 1.15-2.25) and 2.1 times (CI95% 1.12-3.93) higher odds were noted in above median frailty group. CONCLUSIONS: mFI is an independent predictor of mortality among patients undergoing HA and THA for femoral neck fracture beyond traditional risk factors such as age, ASA class, and other comorbidities. LEVELS OF EVIDENCE: Level II.

The ability to return to work (RTW) postinjury is one of the primary goals of rehabilitation. The modified Rankin Scale (mRS) is a validated simple scale used to assess the functional status of stroke patients during rehabilitation. We sought to determine the applicability of mRS in predicting RTW postinjury in a general trauma population. The trauma registry was queried for patients, aged 18 to 65 years, discharged from 2012 to 2013. A telephone interview for each patient included questions about employment status and physical ability to determine the mRS. Patients who had RTW postinjury were compared with those who had not (nRTW). Two hundred and thirty-four patients met the inclusion criteria. Of these, 171 (72.5%) patients RTW and 63 (26.7%) did nRTW. Patients who did nRTW were significantly older, had longer length of stay and higher rates of in-hospital complications. Multivariate analysis revealed that older patients were less likely to RTW (odds ratio = 0.961, P = 0.011) and patients with a modified Rankin score ≤2 were 15 times more likely to RTW (odds ratio = 14.932, P < 0.001). In conclusion, an mRS ≤2 was independently associated with a high likelihood of returning to work postinjury. This is the first study that shows applicability of the mRS for predicting RTW postinjury in a trauma population.

BACKGROUND: Emergency department thoracotomy (EDT) is a formidable and dramatic last attempt by the trauma surgeon to save the life of a patient in extremis. The aim of this report is to provide a benchmark for comparison with past results by reviewing all available published data since the American College of Surgeons Committee on Trauma review article in 2001, which reviewed literature from 1966 to 1999 regarding indications for and outcomes of EDT. METHODS: A comprehensive literature search in MEDLINE Library databases was performed for EDT. Data were extracted by three independent reviewers. RESULTS: We identified 37 papers with a total of 3466 patients. A total of 85.2% (1720 of the 2018) had penetrating trauma, 58.3% (372 of the 638) had cardiac injuries, 43.0% (251 of the 584) had thoracic injuries and 26.2% (143 of the 546) had abdominal injuries. The overall rate survival in this review was 8% (267 of the 3466, range 0-33.3%). Of 25 papers reporting cases of EDT for penetrating traumas, their survival rate was 9.8% (169 of the 1719, range 0-45.5); similarly, of 14 papers assessing EDT for blunt injuries, the survival rate was 5.2% (24 of the 460, range 0-12.2). Of 15 papers reporting neurological outcomes 84.6% (143 of the 169, range 50-100%) of patients returned to baseline. The survival outcome of EDT in US experience versus non-US experiences was 6.3% (164 of the 2612, range 0-14.9) versus 11.9% (89 of the 745, range 0-33.3) respectively. CONCLUSION: The authors intend this review to serve as a practical and prompt literature search tool for all surgeons who encounter resuscitative thoracotomy in their practice.

BACKGROUND: Bladder and/or urethral injuries (BUIs) secondary to pelvic fractures are rare in children and are associated with a high morbidity. These injuries are much less likely to occur in females and are often missed in the emergency department. To help clinicians detect these injuries in female children, larger studies are needed to identify risk factors specific to this patient population. This study aimed to identify risk factors associated with BUI in female children with a pelvic fracture. METHODS: We reviewed the National Trauma Data Bank for females younger than 16 years who sustained a pelvic fracture from 2010 to 2012. Patients with penetrating injuries were excluded. Variables including patient characteristics, mechanism of injury, and type of pelvic fracture were selected for bivariate analysis. Variables with an association of p < 0.05 were then tested using binary logistic regression. RESULTS: Of the 149,091 females younger than 16 years in the National Trauma Data Bank, 2,639 patients (2%) with pelvic fractures were identified. The median patient age was 12 years (interquartile range [IQR], 7-14 years). BUI was identified in 81 patients (3%). Patients with BUI had a significantly higher median Injury Severity Score (ISS) (25 [IQR, 17-34] vs. 13 [IQR, 6-22], p < 0.001). Four variables were found to be independently associated with BUI in the logistic regression model: vaginal laceration (adjusted odds ratio [OR], 9.1; 95% confidence interval [CI], 4.4-18.7), disruption of the pelvic circle (adjusted OR, 3.0; 95% CI, 1.6-5.6), multiple pelvic fractures (adjusted OR, 2.3; 95% CI, 1.3-3.9), and sacral spine injury (adjusted OR, 1.6; 95% CI, 1.0-2.6). In total, 62 patients (77%; 95% CI, 67-86%) with BUI had at least one of these findings. CONCLUSION: Female children who sustained a pelvic fracture and have a vaginal laceration, disruption of the pelvic circle, multiple pelvic fractures, or a sacral spine injury seem to be at highest risk for BUI. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

Open surgical repair of thoracoabdominal aortic aneurysms remains associated with significant morbidity and mortality. We sought to analyse multicentre national data on early outcomes of open surgical thoracoabdominal aortic aneurysm repair. Patients who underwent open repair of thoracoabdominal aortic aneurysm from 2005 to 2010 were identified from the National Surgical Quality Improvement Program database. The primary endpoint was mortality at 30 days. Patient demographics, clinical variables, and intraoperative parameters were analysed by univariate and multivariate logistic regression methods to identify risk factors for mortality. Of the 682 elective repairs, 30-day outcomes of elective repairs were: 10.0% mortality, 21.6% surgical complications, 42.2% pulmonary complications, 17.2% renal complications, 12.9% cardiovascular complications, 19.2% septic complications, and 6.6% wound complications. Multivariate logistic regression analysis showed that age, ASA-class IV, dependent functional status prior to surgery, and operation time are independent risk factors for mortality. Our study found a higher rate of mortality nationwide, as compared to several previous single center studies.

BACKGROUND: Toxic colitis (TC) is a potentially lethal complication of inflammatory bowel disease and infectious colitis. METHODS: The National Surgical Quality Improvement Project dataset was queried to identify emergent colectomy for a primary diagnosis of TC using International Classification of Diseases, Ninth Revision codes. The study endpoints were 30-day mortality and 30-day morbidity. We performed multivariate logistic regression analyses to study factors associated with 30-day mortality. RESULTS: Of the 189 TC patients, mortality for colectomy was 26.5%, 42.3% experienced pulmonary complications, 20.6% experienced sepsis complications, 17.5% experienced cardiovascular complications, 12.7% experienced renal complications, and 14.8% experienced wound complications. On multivariate analysis, independent factors associated with mortality were age 70 to 80 years (odds ratio [OR] 3.5), age greater than 80 (OR 22.2), female sex (OR 4.1), uremia blood urea nitrogen greater than 40 (OR 4.1), coagulopathy international normalized ratio greater than 2 (OR 7.7), preoperative respiratory failure (OR 2.73), and preoperative steroid use (OR 3.9). CONCLUSIONS: Patients with TC are very ill. Poor outcome is associated with older age, female sex, preoperative azotemia, preoperative respiratory failure, and chronic steroid use. These factors will help acute care surgeons in preoperative risk assessment and could be an important addition to decision-making strategies.

OBJECTIVE: The objective of this study was to evaluate the remodeling of abdominal aortic aneurysms after endovascular aortic aneurysm repair (EVAR) with the Zenith (Cook Medical, Bloomington, Ind) device. METHODS: This was a retrospective study of anatomic data related to characteristics of the aortic neck diameter, iliac artery diameter, and aneurysm sac diameter collected during a clinical study of the Zenith device. RESULTS: In this study, 739 patients were observed for 2 years and 158 of them were observed for 5 years. The monthly rate of change for the neck diameter was more rapid in the early postoperative period (postoperative-30 days), with an expansion of 0.7 ± 0.09 mm/month, and during the third year of follow-up (24-36 months), with a monthly expansion rate of 0.10 ± 0.24 mm. The iliac arteries were also more prone to expansion during the first postoperative month (right iliac, 0.95 ± 0.08 mm/month; left iliac, 0.91 ± 0.08 mm/month) and in the next 6 months with a monthly expansion rate of 0.18 ± 0.02 mm and 0.21 ± 0.02 mm for the right and left iliac arteries, respectively. Remodeling of the aneurysm sac occurred mainly in the first postoperative year with a regression rate of 0.89 ± 0.05 mm/month between 1 and 6 months and 0.44 ± 0.04 mm/month for the second half of the year. The aneurysm sac regression rate dropped to 0.2 mm/month in the second postoperative year. Changes in the aortic neck diameter were statistically significant (P < .001) only at the 24- to 36-month postoperative interval. Changes in the aortic sac diameter were statistically significant (P < .001) at the 30-day to 6-month, 6- to 12-month, and 12- to 24-month intervals. Among patients who underwent reintervention, aortic sac expansion occurred primarily in the 24- to 36-month interval. CONCLUSIONS: Expansion of the aortic neck after EVAR for the Zenith endograft occurs mainly between 24 and 36 months; aortic aneurysm sac regression occurs more obviously at 1 to 12 months. Iliac arteries at the landing zone expand more rapidly in the first postoperative year. Late surveillance of EVAR patients is essential to avoid late complications after aortic remodeling.

BACKGROUND: In 2010, overweight and obesity were estimated to cause 3·4 million deaths, 3·9% of years of life lost, and 3·8% of disability-adjusted life-years (DALYs) worldwide. The rise in obesity has led to widespread calls for regular monitoring of changes in overweight and obesity prevalence in all populations. Comparable, up-to-date information about levels and trends is essential to quantify population health effects and to prompt decision makers to prioritise action. We estimate the global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013. METHODS: We systematically identified surveys, reports, and published studies (n=1769) that included data for height and weight, both through physical measurements and self-reports. We used mixed effects linear regression to correct for bias in self-reports. We obtained data for prevalence of obesity and overweight by age, sex, country, and year (n=19,244) with a spatiotemporal Gaussian process regression model to estimate prevalence with 95% uncertainty intervals (UIs). FINDINGS: Worldwide, the proportion of adults with a body-mass index (BMI) of 25 kg/m(2) or greater increased between 1980 and 2013 from 28·8% (95% UI 28·4-29·3) to 36·9% (36·3-37·4) in men, and from 29·8% (29·3-30·2) to 38·0% (37·5-38·5) in women. Prevalence has increased substantially in children and adolescents in developed countries; 23·8% (22·9-24·7) of boys and 22·6% (21·7-23·6) of girls were overweight or obese in 2013. The prevalence of overweight and obesity has also increased in children and adolescents in developing countries, from 8·1% (7·7-8·6) to 12·9% (12·3-13·5) in 2013 for boys and from 8·4% (8·1-8·8) to 13·4% (13·0-13·9) in girls. In adults, estimated prevalence of obesity exceeded 50% in men in Tonga and in women in Kuwait, Kiribati, Federated States of Micronesia, Libya, Qatar, Tonga, and Samoa. Since 2006, the increase in adult obesity in developed countries has slowed down. INTERPRETATION: Because of the established health risks and substantial increases in prevalence, obesity has become a major global health challenge. Not only is obesity increasing, but no national success stories have been reported in the past 33 years. Urgent global action and leadership is needed to help countries to more effectively intervene.
