ABSTRACT
BACKGROUND: Patients with acute cholecystitis (AC) presenting with unfavorable systemic or local conditions are often managed with percutaneous cholecystostomy (PC) as a temporary measure. The clinical outcomes of interval cholecystectomy following PC remain unclear. The aim of the study was to identify the association between the timing of cholecystectomy following PC for AC and perioperative complication rates at interval cholecystectomy. We hypothesized that there would be a specific time interval to cholecystectomy associated with lower risk for adverse events. METHODS: This was a retrospective (2018-2020) multicenter study at 8 participating hospital systems of adult patients with AC, managed with PC and interval cholecystectomy. Demographics, comorbidities, treatment details, and outcomes were examined. Patients were grouped based on quartiles for timing of surgery after PC (< 7, 7-9, 10-13, > 13 weeks). The primary outcome was a composite endpoint of bile duct injury, reoperation, readmission, image-guided intervention, endoscopic intervention, conversion to open surgery, or death. RESULTS: There were 188 patients with a median age of 66 years with AC classified as mild (41%), moderate (47%), and severe (12%). Median days from PC to surgery were 65 (Q1 = 48, Q3 = 91). Laparoscopic cholecystectomy (89.9%) was the most commonly planned approach (robotic 6.4%, 3.7% open) and 28 (14.9%) were converted to open. The composite endpoint was reported in 51 patients (27.1%). A biliary injury occurred in 7 (3.7%) patients. Time to surgery and intraoperative drain placement were independently associated with the composite outcome. Cholecystectomy within 7 weeks of PC was associated with decreased risk (OR = 0.36, 95% CI 0.13-0.97) of the composite endpoint, compared to patients undergoing surgery > 13 weeks after PC. CONCLUSION: Timing of surgery following PC was associated with procedural outcomes. Patients undergoing surgery before 7 weeks experienced significantly less morbidity than patients having delayed cholecystectomy. These results should be considered in patient selection and management after PC.
ABSTRACT
OBJECTIVE: To define the impact of missed ordering of venous thromboembolism (VTE) chemoprophylaxis in high-risk general surgery populations. BACKGROUND: The primary cause of preventable death in surgical patients is VTE. Although guidelines and validated risk calculators assist in dosing recommendations, there remains considerable variability in ordering and adherence to recommended dosing. METHODS: All adult inpatients who underwent a general surgery procedure between 2016 and 2019 and were entered into Atrium Health National Surgical Quality Improvement Program registry were identified. Patients at high risk for VTE (2010 Caprini score ≥5) and without bleeding history and/or acute renal failure were included. Primary outcome was 30-day postoperative VTE. Electronic medical record identified compliance with "perfect" VTE chemoprophylaxis orders (pVTE): no missed orders and no inadequate dose ordering. Multivariable analysis examined association between pVTE and 30-day VTE events. RESULTS: A total of 19,578 patients were identified of which 4252 were high-risk inpatients. Hospital compliance of pVTE was present in 32.4%. pVTE was associated with shorter postoperative length of stay and lower perioperative red blood cell transfusions. There was 50% reduced odds of 30-day VTE event with pVTE (odds ratio: 0.50; 95% CI, 0.30-0.80) and 55% reduction in VTE event/mortality (odds ratio: 0.45; 95% CI, 0.31-0.63). After controlling for relevant covariates, pVTE remained significantly associated with decreased odds of VTE event and VTE event/mortality. CONCLUSIONS: pVTE ordering in high-risk general surgery patients was associated with 42% reduction in odds of postoperative 30-day VTE. Comprehending factors contributing to missed or suboptimal ordering and development of quality improvement strategies to reduce them are critical to improving outcomes.

BACKGROUND: During the COVID-19 pandemic, public health and hospital policies were enacted to decrease virus transmission and increase hospital capacity. Our aim was to understand the association between COVID-19 positivity rates and patient presentation with EGS diagnoses during the COVID pandemic compared to historical controls. METHODS: In this cohort study, we identified patients ≥ 18 years who presented to an urgent care, freestanding ED, or acute care hospital in a regional health system with selected EGS diagnoses during the pandemic (March 17, 2020 to February 17, 2021) and compared them to a pre-pandemic cohort (March 17, 2019 to February 17, 2020). Outcomes of interest were number of EGS-related visits per month, length of stay (LOS), 30-day mortality and 30-day readmission. RESULTS: There were 7908 patients in the pre-pandemic and 6771 in the pandemic cohort. The most common diagnoses in both were diverticulitis (29.6%), small bowel obstruction (28.8%), and appendicitis (20.8%). The lowest relative volume of EGS patients was seen in the first two months of the pandemic period (29% and 40% decrease). A higher percentage of patients were managed at a freestanding ED (9.6% vs. 8.1%) and patients who were admitted were more likely to be managed at a smaller hospital during the pandemic. Rates of surgical intervention were not different. There was no difference in use of ICU, ventilator requirement, or LOS. Higher 30-day readmission and lower 30-day mortality were seen in the pandemic cohort. CONCLUSIONS: In the setting of the COVID pandemic, there was a decrease in visits with EGS diagnoses. The increase in visits managed at freestanding ED may reflect resources dedicated to supporting outpatient non-operative management and lack of bed availability during COVID surges. There was no evidence of a rebound in EGS case volume or substantial increase in severity of disease after a surge declined.

BACKGROUND: The aim of this study was to evaluate the use of laparoscopic surgery for common emergency general surgery (EGS) procedures within an integrated Acute Care Surgery (ACS) network. We hypothesized that laparoscopy would be associated with improved outcomes. METHODS: Our integrated health care system's EGS registry created from AAST EGS ICD-9 codes was queried from January 2013 to October 2015. Procedures were grouped as laparoscopic or open. Standard descriptive and univariate tests were performed, and a multivariable logistic regression controlling for open status, age, BMI, Charlson Comorbidity Index (CCI), trauma tier, and resuscitation diagnosis was performed. Laparoscopic procedures converted to open were identified and analyzed using concurrent procedure billing codes across episodes of care. RESULTS: Of 60,604 EGS patients identified over the 33-month period, 7280 (12.0%) had an operation and 6914 (11.4%) included AAST-defined EGS procedures. There were 4813 (69.6%) surgeries performed laparoscopically. Patients undergoing a laparoscopic procedure tended to be younger (45.7 ± 18.0 years vs. 57.2 ± 17.6, p < 0.001) with similar BMI (29.7 ± 9.0 kg/m2 vs. 28.8 ± 8.3, p < 0.001). Patients in the laparoscopic group had lower mean CCI score (1.6 ± 2.3 vs. 3.4 ± 3.2, p ≤ 0.0001). On multivariable analysis, open surgery had the highest association with inpatient mortality (OR 8.67, 4.23-17.75, p < 0.0001) and at all time points (30-, 90-day, 1-, 3-year). At all time points, conversion to open was found to be a statistically significant protective factor. CONCLUSION: Use of laparoscopy in EGS is common and associated with a decreased risk of all-cause mortality at all time points compared to open procedures. Conversion to open was protective at all time points compared to open procedures.

BACKGROUND: The Emergency General Surgery (EGS) population is particularly at high risk for readmission. Currently, no system exists to predict which EGS patients are most at risk. We hypothesized that a subset of EGS patients could be identified with increased 30-day unplanned readmission. We also hypothesized that a majority of readmissions occur sooner than the conventional 2-week follow-up period. METHODS: National Surgical Quality Improvement Program (NSQIP) nonelective general surgery patients were analyzed. Multivariable logistic regression identified factors with increased odds of unplanned readmission. AAST EGS Diagnosis Categories were used to categorize postop ICD-9 codes, and the top 10 CPT codes in each group were analyzed. Readmission rate, the reason for unplanned readmission, and time to readmission were analyzed. RESULTS: A total of 383,726 patients were identified with a readmission rate of 8.1% within 30 d of their primary procedure. The top 50 CPT codes accounted for 84% of EGS readmissions. Increased readmission risk was demonstrated for underweight patients (OR = 1.15, P < 0.05). High-risk hospital characteristics were LOS >2 d, any inpatient pulmonary complications, and discharge to any facility or rehab (all P < 0.05). Surgical site infections cause nearly 25% of readmissions. Intestinal procedures are most frequently readmitted (22% of EGS readmissions), with colorectal procedures having the higher odds of readmission. Most readmissions occur <10 d after discharge. CONCLUSIONS: A high-risk subpopulation exists within EGS, and most readmissions occur sooner than a typical 2-week follow-up. Early interventions for high-risk EGS subpopulations may allow for early intervention and reduction of unnecessary healthcare utilization.

OBJECTIVES: The aim of this study was to examine the outcomes of over a decade's experience utilizing preperitoneal ventral hernia repair (PP-VHR). BACKGROUND: PP-VHR was first described by our group in 2006, and there have been no subsequent reports of outcomes with this technique. METHODS: A prospective study of all PP-VHR from January, 2004 to April, 2016 was performed. Multivariate stepwise logistic regression and Cox proportional-hazard models were used to identify predictors of wound complications and hernia recurrence, respectively. RESULTS: There were 1023 PP-VHRs. Mean age was 57.2â±â12.6 years, BMI 33.7â±â11.4âkg/m, defect size 210.0â±â221.4âcm; 23.7% had diabetes, 13.9% were smokers, 68.7% were recurrent, and 23.6% incarcerated. Component separation was required in 43.6%, and a panniculectomy was performed in 30.0%. Wound complication was present in 27.3% of patients, with 1.7% having a mesh infection. In all, there were 53 (5.2%) hernia recurrences and 36 (3.9%) in the synthetic repairs, with a mean follow-up of 27.0â±â26.4 months. On multivariate regression (odds ratio or hazard ratio, 95% confidence interval), diabetes (1.9, 1.4-3.0), panniculectomy (2.6, 1.8-3.9), and operations requiring biologic mesh were predictors of wound complications, whereas recurrent hernia repair (2.69, 1.14-6.35), biologic mesh (3.1, 1.67-5.75), and wound complications (3.01, 1.69-5.39) were predictors of hernia recurrence. CONCLUSIONS: An open PP-VHR is a very effective means to repair large, complex, and recurrent hernias resulting in a low recurrence rate. Mesh choice in VHR is important and was associated with hernia recurrence and wound complications in this population.

BACKGROUND: While the prevalence of HIV infection in the population is 0.5%, it is higher among trauma patients as are rates of unknown seropositivity. Routine HIV screening for all trauma evaluations was implemented at our urban level I center in 2009. We aimed to evaluate use and results of the program in our trauma population. METHODS: This was a retrospective analysis of all trauma evaluations between July 2015 and February 2018. After passage of legislation rescinding the requirement for consent to perform HIV testing, our trauma service instituted an order set which automatically tested for HIV unless the ordering physician opted out. Patients found to be infected with HIV were to be counseled and referred to specialty care. RESULTS: Of 6175 consecutive trauma evaluations during the study period, 449 (7.3%) patients had been screened within the prior year and were excluded. Of the remaining cohort, 2024 (35.3%) patients were screened with 27 (1.3%) testing positive. Among those testing positive for infection, 100% were male, 77% white, 63% non-Hispanic, and 70% lacked insurance. Twenty-five (92.6%) patients received counseling and 19 were referred to specialty care. Age, gender, race, ethnicity, Injury Severity Score, trauma activation level, and payor type were not significant predictors for positive HIV screen on logistic regression analysis. CONCLUSIONS: Despite a significantly higher rate of HIV in the trauma population, only a third of patients are screened. Such high infection rates justify the existence of this screening program but steps must be taken to increase screening rate. LEVEL OF EVIDENCE: Level 3.

INTRODUCTION: Early removal of urinary catheters is an effective strategy for catheter-associated urinary tract infection (CAUTI) prevention. We hypothesized that a nurse-directed catheter removal protocol would result in decreased catheter utilization and CAUTI rates in a surgical trauma intensive care unit (STICU). METHODS: We performed a retrospective, cohort study following implementation of a multimodal CAUTI prevention bundle in the STICU of a large tertiary care center. Data from a 19-month historical control were compared to data from a 15-month intervention period. Pre- and postintervention indwelling catheter utilization and CAUTI rates were compared. RESULTS: Catheter utilization decreased significantly with implementation of the nurse-driven protocol from 0.78 in the preintervention period to 0.70 in the postintervention period (P < .05). As a result of the bundle, the CAUTI rate declined significantly, from 5.1 to 2.0 infections per 1000 catheter-days in the pre- vs postimplementation period (Incident Rate Ratio [IRR]: 0.38, 95% confidence interval: 0.21-0.65). CONCLUSIONS: Implementation of a nurse-driven protocol for early urinary catheter removal as part of a multimodal CAUTI intervention strategy can result in measurable decreases in both catheter utilization and CAUTI rates.

BACKGROUND: Minimally invasive surgery (MIS) has demonstrated superior outcomes in many elective procedures. However, its use in emergency general surgery (EGS) procedures is not well characterized. The purpose of this study was to examine the trends in utilization and outcomes of MIS techniques in EGS over the past decade. METHODS: The 2007-2016 ACS-NSQIP database was utilized to identify patients undergoing emergency surgery for four common EGS diagnoses: appendicitis, cholecystitis/cholangitis, peptic ulcer disease, and small bowel obstruction. Trends over time were described. Preoperative risk factors, operative characteristics, outcomes, morbidity, and trends were compared between MIS and open approaches using univariate and multivariate analysis. RESULTS: During the 10-year study period, 190,264 patients were identified. The appendicitis group was the largest (166,559 patients) followed by gallbladder disease (9994), bowel obstruction (6256), and peptic ulcer disease (366). Utilization of MIS increased over time in all groups (p < 0.001). There was a concurrent decrease in mean days of hospitalization in each group: appendectomy (2.4 to 2.0), cholecystectomy (5.7 to 3.2), peptic ulcer disease (20.3 to 11.7), and bowel obstruction (12.9 to 10.5); p < 0.001 for all. On multivariate analysis, use of MIS techniques was associated with decreased odds of 30-day mortality, surgical site infection, and length of hospital stay in all groups (p < 0.001). CONCLUSIONS: Use of MIS techniques in these four EGS diagnoses has increased in frequency over the past 10 years. When adjusted for preoperative risk factors, use of MIS was associated with decreased odds of wound infection, death, and length of stay. Further studies are needed to determine if increased access to MIS techniques among EGS patients may improve outcomes.

BACKGROUND: Despite advances in diagnostic imaging capabilities, little information exists concerning the impact of physical dimensions of a paraesophageal hernia (PEH) on intraoperative decision making. The authors hypothesized that computerized volumetric analysis and multidimensional visualization to measure hiatal defect area (HDA) and intrathoracic hernia sac volume (HSV) would correlate to operative findings and required surgical techniques performed. METHODS: Using volumetric analysis software (Aquarius iNtuition, TeraRecon, Inc), HDA and HSV were measured in PEH patients with preoperative computerized tomography (CT) scans, and used to predict the likelihood of intraoperative variables. Multidimensional rotation of images enabled visualization of the entire hiatal defect in a plane mimicking the surgeon's view during repair. The intrathoracic hernia sac was outlined producing volume measurements based on a summation of exact dimensions. RESULTS: A total of 213 PEHR patients had preoperative CT imaging, with 14.1% performed emergently. Primary cruroplasty was performed in 89.2%, salvage gastropexy in 10.3%, and diaphragmatic relaxing incisions in 4.2%. Median HDA was 25.7 cm2 (IQR17.8-35.6 cm2); median HSV was 365.0 cm3 (IQR150.0-611.0 cm3). Incremental 5 cm2 increase in HDA was associated with greater likelihood of presenting emergently (OR 1.27; 95%CI 1.124-1.428, p = 0.0001), incarceration (OR 1.27; 1.074-1.499, p = 0.005), gastric volvulus (OR 1.13; 1.021-1.248, p = 0.02), and requiring either relaxing incision (OR 1.43; 1.203-1.709, p < 0.0001) or salvage gastropexy (OR 1.13; 1.001-1.274, p = 0.04). Similarly, HSV increases of 100 cm3 were associated with 23% greater likelihood of emergent repair (CI 1.121-1.353, p < 0.0001), and were more likely to require a relaxing incision (OR 1.18; 1.043-1.339, p = 0.009) or salvage gastropexy (1.19; 1.083-1.312, p = 0.0003). CONCLUSIONS: Utilization of CT volumetric measurements is a valuable adjunct in preoperative planning, allowing the surgeon to anticipate complexity of repair and operative approach, as incremental increases in HSV by 100 cm3 and HDA by 5 cm2 are more likely to require complex techniques or bailout procedures and/or present emergently.

BACKGROUND: Transabdominal, preperitoneal (TAPP), laparoscopic inguinal hernia repair (IHR) requires the creation of a peritoneal flap (PF) that must be closed after mesh placement. Our previous study indicated that sutured PF closure resulted in less short-term postoperative pain at 2 and 4 weeks compared to tacks and staples. Therefore, the aim of this follow-up study was to compare short-term QOL with a greater sample size and long-term QOL at 2 years by method of PF closure. MATERIALS AND METHODS: A prospective institutional hernia-specific database was assessed for all adult TAPP IHRs from July 2012 to May 2015. QOL outcomes were compared by PF closure method at 2 and 4 weeks and 6, 12, and 24 months as measured by the Carolinas Comfort Scale. Standard statistical tests were used for the whole population and then the Bonferroni Correction was used to compare groups (p < 0.0167). Multivariate analysis controlling for age, gender, recurrent hernias, and preoperative symptomatic pain was used to compare QOL by PF closure method. RESULTS: A total of 679 TAPP IHRs in 466 patients were analyzed; 253 were unilateral, and 213 were bilateral. PF closure was performed using tacks in 36.7 %, suture in 24.3 %, and staples in 39.0 %. There was no difference in hernia recurrence (only 1 patient at 36 months). There were no statistical differences in QOL between 2 and 4 weeks and 6- to 24-month follow-up. When resolution of symptoms from preoperative levels was examined, there was no difference in the three groups at any time point (p > 0.05). After controlling for confounding variables on multivariate analysis, there was no difference in QOL by PF closure method at any time point (p > 0.05). CONCLUSION: Tacked, sutured, and stapled techniques for peritoneal flap closure following TAPP have no significant differences in operative outcomes, postoperative quality of life, or resolution of symptoms.

BACKGROUND: The purpose of this prospective, randomized, double-blinded controlled trial was to investigate the utility of indocyanine green fluorescence angiography (ICG-FA) in reducing wound complications in complex abdominal wall reconstruction. MATERIALS AND METHODS: All consented patients underwent ICG-FA with SPY Elite after hernia repair and before flap closure. They were randomized into the control group, in which the surgical team was blinded to ICG-FA images and performed surgery as they normally would, or the experimental group, in which the surgery team viewed the images and could modify tissue flaps according to their findings. Patient variables and wound complications were compared with standard statistical methods. RESULTS: Among 95 patients, n = 49 control versus n = 46 experimental, preoperative characteristics were similar including age (58.3 versus 56.7 y; P = 0.4), body mass index (34.9 versus 33.6 kg/m(2); P = 0.8), tobacco use (8.2% versus 8.7%; P = 0.9), diabetes (30.6% versus 37.0%; P = 0.5), and previous hernia repair (71.4% versus 60.9%; P = 0.3). Operative characteristics were also similar, including rate of panniculectomy (69.4% versus 58.7%; P = 0.3) and component separation (73.5% versus 69.6%; P = 0.6). The experimental group more often had advancement flaps modified (37% versus 4.1%, P < 0.0001). There was no difference between groups in rates of skin necrosis (6.1% versus 2.2%; P = 0.3), fat necrosis (10.2% versus 13.0%, P = 0.7), reoperation (14.3% versus 26.1%, P = 0.7), wound infection (10.2% versus 21.7%; P = 0.12), or overall wound-related complications (32.7% versus 37.0%, P = 0.7). Skin/subcutaneous hypoperfusion on ICG-FA was associated with higher rates of wound infection (28% versus 9.4%, P < 0.02), but flap modification after viewing images did not prevent wound-related complications (15.6% versus 12.5%, P = 0.99). CONCLUSIONS: This is the first randomized, double-blinded, controlled trial to evaluate ICG-FA in abdominal wall reconstruction. Although ICG-FA guidance and intraoperative modification of flaps did not prevent wound-related complications or reoperation, it did identify at risk patients.

BACKGROUND: Preoperative imaging with computed tomography (CT) scans can be useful in preoperative planning. We hypothesized that CT measurements of ventral hernia defect size and abdominal wall thickness (AWT) would correlate with postoperative complications and need for complex abdominal wall reconstruction (AWR). MATERIALS AND METHODS: Patients who underwent open ventral hernia repair and had preoperative abdominal CT imagining were identified from an institutional hernia-specific surgery outcomes database at our tertiary referral hernia center. Grade III and IV hernias and biologic mesh cases were excluded. CT measures of defect size and AWT were analyzed and correlated to complications and the need for AWR techniques using univariate, multivariate, and principal component (PC) analyses. PC1 and PC2 used five AWT measures, hernia defect width, and body mass index to create a new component variable. RESULTS: There were 151 open ventral hernia repairs included in the study. Preoperative findings included 37.7% male; age 55.3 ± 12.5 years; body mass index (BMI) 33.3 ± 7.8 kg/m(2); 60.3% were recurrent hernias with average defect width 8.5 ± 5.0 cm and area 178.3 ± 214 cm(2); AWT at umbilicus 3.5 ± 1.8 cm; and AWT at pubis 7.0 ± 3.2. Component separation was performed in 24.0% of patients and panniculectomy in 34.4%. Wound complications occurred in 13.3% patients, and 2.7% had hernia recurrence. Increasing defect width, length, and area as well as select AWT measurements were associated with increased need for component separation, concomitant panniculectomy, and higher rates of wound and total complications (all P < 0.05). Using multivariate regression, PC1 was associated with wound complications (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.01-1.16); PC2 (hernia defect width) was associated with the need for component separation (OR, 1.16; 95% CI, 1.03-1.30). Hernia recurrence was not predicted by AWT or defect size (OR, 1.00; 95%CI, 0.87-1.15). CONCLUSIONS: Preoperative CT measurements of hernia defects and AWT predict wound complications and the need for complex AWR techniques. Obtaining preoperative CT imaging should be a consideration in preoperative planning and may help with patient counseling.

INTRODUCTION: Laparoscopic Heller myotomy (LHM) has supplanted an open approach due to decreased operative morbidity. Our goal was to quantify the incidence of peri-operative complications and identify risk factors for adverse outcomes in LHM. METHODS: All LHM were queried from 2005 to 2011 from the National Surgical Quality Improvement Program database. Adverse outcomes were identified, and univariate and stepwise logistic regression (MVR) was then performed to quantify association. RESULTS: There were 1,237 LHM in the study period. Patient averages were: age 51.9 ± 16.8 years, BMI 27.3 ± 6.6 kg/m(2), Charlson comorbidity index (CCI) 0.2 ± 0.6. 15.3 % had >10 % body mass loss in the preoperative 6 months. During surgery, 10.2 % underwent concomitant EGD, and mean operative time was 141.6 ± 63.4 min. There were 7(0.06 %) wound complications, 22(1.8 %) general complications, and 30(2.4 %) major complications. Average length of stay (LOS) was 2.8 ± 5.5 days. The rate of readmission and reoperation were 3.1 and 2.3 %, respectively, and there were 4(0.03 %) deaths. General and major complications were associated with alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times (p < 0.05); however, these factors did not remain significant on MVR (p > 0.05). Operative time was found to be significantly longer by 35.3 min for inpatients, 43.1 min in functionally dependent patients, 50.0 min in preoperative septic patients, and 17.2 min with concomitant EGD (p < 0.01 for all). LOS was found to be longer by 1.9 days for inpatients, 1.8 days in ASA category ≥3, and 1.2 days per one point increase in CCI (p < 0.001 for all). CONCLUSION: LHM is being performed nationally with a low incidence of operative complications and mortality. General and major complications following LHM are associated with patient alcohol use, pack-years of smoking, weight loss, history of stroke, radiation therapy, and longer operative times. Additionally, independent predictors of longer operative time and LOS were identified.

INTRODUCTION: TAPP inguinal hernia repair (IHR) entails the development of a peritoneal flap (PF) in order to reduce the hernia sac and create a preperitoneal space in which to place mesh. Many methods for closure of the PF exist including sutures, tacks, and staples. We hypothesized that patients who had PF closure with suture would have better short-term QOL outcomes. METHODS AND PROCEDURES: A prospective institutional hernia-specific database was queried for all adult, TAPP IHRs from July 2012 to August 2013. Unilateral and bilateral patients were included and each hernia was analyzed separately. The main outcome of interest was quality of life (QOL) at two- and four-week follow-up, as measured by the Carolinas Comfort Scale. RESULTS: There were 227 patients who underwent TAPP, with 99 bilateral and 128 unilateral IHR, for a total of 326 IHR. PF closure was performed using tacks in 45.1%, suture in 19.0%, and staples in 35.9%. Patient characteristics were statistically similar between the tack, suture, and staple group. There were 32.9% direct, 46.5% indirect, and 20.6% pantaloon hernias, which were not significantly different when compared by PF closure method. Post-operative complications and length of stay were same for the three groups. There were no hernia recurrences. Post-operative activity limitation at two weeks was significantly better in the suture group when compared to the stapled group (p = 0.005). Additionally, sutured PF closure had less early post-operative pain when compared to the tack group (p = 0.038). CONCLUSIONS: Following TAPP IHR, suture closure of the PF significantly improves 2-week post-operative movement limitation compared to stapled and tacked PF closure. Continued randomized studies are needed to determine the best surgical hernia repair methods for ideal post-op QOL.

PURPOSE OF REVIEW: Anthracyclines have markedly improved the survival rates of children with cancer. However, anthracycline-related cardiotoxicity is also well recognized and can compromise the long-term outcome in some patients. The challenge remains of how to balance the chemotherapeutic effects of anthracycline treatment with its potentially serious cardiovascular complications. Here, we review the pathophysiology, risk factors, clinical manifestations, prevention, and treatment of anthracycline-related cardiotoxicity. RECENT FINDINGS: Some risk factors and biomarkers associated with an increased probability of anthracycline-related cardiotoxicity have been identified. Modifying the structural forms and dosages of anthracyclines and coadministering cardioprotective agents may prevent some of these cardiotoxic effects. Cardiovascular complications have also been treated with angiotensin-converting enzyme inhibitors, ß-blockers, and growth hormone replacement therapy. Cardiac transplantation remains the treatment of last resort. SUMMARY: Despite major advances in cancer treatment, anthracycline-related cardiotoxicity remains a major cause of morbidity and mortality in survivors of childhood cancer. Promising areas of research include: use of biomarkers for early recognition of cardiac injury in children receiving chemotherapy, development and application of cardioprotective agents for prevention of cardiotoxicity, and advancements in therapies for cardiac dysfunction in children after anthracycline treatment.

Children diagnosed with cancer are now living longer as a result of advances in treatment. However, some commonly used anticancer drugs, although effective in curing cancer, can also cause adverse late effects. The cardiotoxic effects of anthracycline chemotherapy, such as doxorubicin, and radiation can cause persistent and progressive cardiovascular damage, emphasizing a need for effective prevention and treatment to reduce or avoid cardiotoxicity. Examples of risk factors for cardiotoxicity in children include higher anthracycline cumulative dose, higher dose of radiation, younger age at diagnosis, female sex, trisomy 21 and black race. However, not all who are exposed to toxic treatments experience cardiotoxicity, suggesting the possibility of a genetic predisposition. Cardioprotective strategies under investigation include the use of dexrazoxane, which provides short- and long-term cardioprotection in children treated with doxorubicin without interfering with oncological efficacy, the use of less toxic anthracycline derivatives and nutritional supplements. Evidence-based monitoring and screening are needed to identify early signs of cardiotoxicity that have been validated as surrogates of subsequent clinically significant cardiovascular disease before the occurrence of cardiac damage, in patients who may be at higher risk.

INTRODUCTION: The purpose of this study was to analyze the effect of residents on patient outcomes in laparoscopic ventral hernia repair (LVHR).We hypothesized that increasing postgraduate year (PGY) level would correlate with better outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2005 to 2011 for elective LVHR. Attending only cases were used as the control, and resident cases were stratified into junior (PGY 1-3), chief (4-5), and fellow (6+) cases. Standard statistical tests and multivariate regression controlling for age, body mass index, Charlson comorbidity index, smoking, functional status, and inpatient cases were performed for trainee involvement and PGY level. RESULTS: There were 6,841 ventral hernia repairs that met inclusion criteria: 2,773 attending and 4,068 resident cases. There were 1,644 junior, 1,983 chief, and 441 fellow cases. Patients were similar between the attending and resident groups. The resident group had a higher rate of inpatient cases, general complications, longer operative time, and hospital length of stay. After controlling for confounders in multivariate analysis, only operative time was significantly different; resident cases were 17.7 min longer (CI 15.0-20.6; p < 0.001). There was no significant difference in the rate of wound or major complications, readmission, reoperation, or mortality between attending and resident cases. Demographics were not significantly different between the PGY level strata. On multivariate regression by PGY level with attending alone as the reference, only operative time was significantly different. Juniors (15.7 min, CI 12.2-19.2), chiefs (18.0 min, CI 14.7-21.3), and fellows (24.9 min, CI 19.1-30.7) had significantly longer cases than attending alone; all p < 0.001. CONCLUSION: Trainee involvement during LVHR does not change the clinical outcomes for patients as compared to those performed by an attending only. Operative time is significantly longer with increasing PGY level, perhaps indicating the complexity of the operation or increasing trainee involvement as primary surgeon. However, patient care does not suffer, affirming the current surgical training curriculum is appropriate.

Atypical motor behaviors are common among children with autism spectrum disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among 6-month-olds at increased risk (high risk) for ASD (N1 = 129; N2 = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high-risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free-play) context than infants with no family history of ASD. Longitudinal assessments suggest that between 6 and 10 months, grasping activity increases in high-risk infants.
