Published: June 2020

Despite the incorporation of anticoagulant and antiplatelet (ACAP) drugs in our trauma triage criteria, it is unclear whether trauma team activation (TTA) impacts outcomes in geriatric patients on ACAP drugs sustaining falls. We hypothesized that TTA in this cohort was associated with improved outcomes. The hospital electronic database was queried to identify normotensive, awake patients aged ≥65 years on ACAP agent from 2014 to 2018 presenting to the emergency department after falls. The outcome was in-hospital mortality. The association between TTA and mortality was examined using logistic regression analysis and 1:1 propensity score matching analysis. In this study, 4540 patients on ACAP drugs were analyzed, with TTA occurring in 500 (11%). TTA occurred in younger but more severely injured patients with lower Glasgow Coma Score. Logistic regression revealed that TTA was not associated with mortality (odds ratio [95% confidence intervals], 2.04 [0.89–4.25]). The 1:1 propensity score analysis revealed similar mortality for the matched groups (non-TTA, 1.6% vs TTA, 2.2%, P = 0.64). In the elderly patients on ACAP agents, the current triage criteria resulted in the appropriate use of TTA for more severely injured patients. The lack of outcome benefit suggests that ACAP drug use as a criterion for TTA should be re-evaluated.

There is an absence of literature regarding nasoorbitoethmoid (NOE) facial fractures. Although NOE fractures are uncommon, there are a significant number in the pediatric population. These fractures also often occur in conjunction with other facial fractures because the NOE region adjoins the nose, orbit, maxilla, and cranium. They can also be a harbinger for more serious concerns such as traumatic brain injury and intracranial hemorrhage. For this reason, NOE fractures can be highly complicated and a challenge to manage. We aim to define the etiologies and patterns of NOE fractures to guide hospital and surgical management strategies. From 2001 to 2014, 15 pediatric patients were identified as having sustained an NOE fracture. Four (26.7%) of the patients were female and 11 (68.8%) were male. Average age was 11.40. The most common etiologies recorded were motor vehicle accident (n = 8), pedestrian struck (n = 3), and assault (n = 2). Orbital fracture (n = 13), nasal fracture (n = 13), and frontal sinus fracture (n = 10) were the most commonly associated facial fractures sustained alongside NOE fracture. Several patients sustained traumatic brain injury (n = 11) and loss of consciousness (n = 13). The mean Glasgow Coma Score was 10.5. In addition, eight required intubation and five required a surgical airway. Thirteen of the patients were admitted to the ICU and eight required surgical management for their fractures. Titanium plates were most commonly used (n = 4) for surgical management. Alternatively, resorbable implants were used for two patients. The remaining two were treated with closed reduction.

Although gallbladder disease (GBD) is more common in females, we have noticed a trend toward more complicated cases in male patients. We reviewed all cholecystectomies performed at our institution over the last five years. After eliminating cases with confounding variables, we identified 1529 records. Charts were reviewed for age, gender, BMI, procedure performed, operative time, length of stay, and preoperative diagnosis. Descriptive and inferential statistical analyses were conducted along with linear regression. There were 1444 laparoscopic, 64 laparoscopic converted to open, and 21 primary open cases. Patients were 1008 (66%) females and 521 (34%) males. Average operative time was 89.8 minutes. Cholecystectomy averaged 17.7 minutes longer in males ( P = 0.0046). Two per cent of female patients and 7.9 per cent male patient converted to open. Males were more likely to have complicated GBD, whereas women had uncomplicated disease. Average age was 51.9 years for males versus 42.7 years for females. Age, gender, BMI, length of stay, and preoperative diagnosis were all independently significant in predicting operative time. In our study, women presented with uncomplicated GBD, whereas men presented with complicated GBD. This suggests that male patients present at a later stage of disease.

Published: June 2020

The effect of mammographic screening on the natural history and evolution of breast cancer treatment cannot be overstated; however, despite intensive and resource consuming screening, advanced breast cancer is still diagnosed frequently. The development of three-dimensional mammography or digital breast tomosynthesis (DBT) has already demonstrated greater sensitivity in the diagnosis of breast pathology and effectiveness in identifying early breast cancers. In addition to being a more sensitive screening tool, other studies indicate DBT has a lower call-back rate when compared with traditional DM. This study compares call-back rates between these two screening tools. A single institution, retrospective review was conducted of almost 20,000 patient records who underwent digital mammography or DBTin the years 2016 to 2018. These charts were analyzed for documentation of imaging type, Breast Imaging Reporting and Data System 0 status, call-back status, and type of further imaging that was required. Charts for 19,863 patients were reviewed, 17,899 digital mammography examinations were conducted compared with 11,331 DBT examinations resulting in 1,066 and 689 Breast Imaging Reporting and Data System 0 studies, respectively. Of the DM call-backs, 82.08 per cent were recommended for additional radiographic imaging and 17.82 per cent for ultrasound imaging. In the DBT group, only 39.77 per cent of callbacks were recommended for additional radiographic imaging and 60.09 per cent for ultrasound imaging. Our data suggest that DBT results in less call-back for additional mammographic images as compared with digital mammography. DBT may offer benefits over DM, including less imaging before biopsy, less time before biopsy, quicker diagnosis, and improved patient satisfaction.

Published: June 2020

In recent years, nonoperative management of complicated appendicitis has become more common. Patients managed nonoperatively do well, but there is a paucity of literature on patients who fail nonoperative management. The purpose of this study was to examine the overall failure rate, morbidity associated with failure, and potential predictors of failure in nonop management of appendicitis. This is a descriptive retrospective review of patients from a single hospital system who were diagnosed with advanced appendicitis and underwent nonop management between January 1, 2007, and November of 2017. The data were obtained through review of patient charts from the electronic medical record. Failure was defined as requirement of an operation due to ongoing infection secondary to appendicitis. There were 183 patients initially managed non-operatively, with 70 patients failing nonoperative management. Patients failing nonoperative management experienced longer hospitalization (6.2 vs 2.9 days, P < 0.0001), and more patients in the failure group required admission to the ICU (10.0% vs 1.8%, P = 0.028). Multivariate analysis revealed that longer duration of symptoms reduced the likelihood of failure (odds ratio: 0.77 [0.64–0.92]). In this retrospective review, 38 per cent of patients failed nonop management of appendicitis. Symptom duration could provide insight for clinicians in assessing the role of non-operative management because increasing symptom duration reduced the likelihood of failure.

Published: June 2020

The aim of this study was to evaluate the impact of prehospital antiplatelet and/or anticoagulant (APAC) use on treatment and outcomes in patients with severe blunt chest injury. Patients with three or more rib fractures and a hospital length of stay (LOS) > three days admitted from 2014 to 2015 were included. Demographics, mortality, complications, injuries, hospital and ICU LOS, use of blood products, and thoracostomy were studied. Of 383 patients, 27.4 per cent were on APAC medication. Patients on APAC were older ( P < 0.0001), had higher Glasgow Coma Score ( P < 0.0001), and had lower Injury Severity Score ( P < 0.0001) and total number of fractures ( P = 0.0013) than the non-APAC group. APAC was not a predictor of mortality with or without age adjustment. In multiple linear regressions, APAC did not predict an increased LOS. APAC patients did not demonstrate an increase in admission diagnosis or complication of hemothorax, blood transfusions, tube thoracostomy, tracheostomy, LOS, or mortality rates. Similar findings are present in the subgroup of patients studied with high kinetic energy mechanism of injury. Our study does not support the perceived morbidity of APAC therapy in patients with severe blunt chest injury.

Published: June 2020

Debate remains regarding the timing of laparoscopic cholecystectomy after emergent endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis. We hypothesized that patients undergoing early laparoscopic cholecystectomy would have fewer operative complications and a lower conversion rate. This study is a retrospective review of an ERCP database from 2012 to 2016 of adults with a diagnosis of cholangitis secondary to choledocholithiasis who underwent ERCP followed by a laparoscopic cholecystectomy. Patient demographics, ERCP details, timing of operation (<72 hours vs >72 hours after ERCP), complications, and mortality were recorded. Analysis included chi-square, Fisher's exact, and Wilcoxon rank-sum tests, where appropriate. In the 127 patients (65 per cent male; median age, 67 years; 48 (38%) early surgery), there were no differences in demographics, BMI, vital signs, or laboratory values. Patients in the late surgery group were more likely to have a Charlson Comorbidity Index > 3 ( P = 0.002), require pre-operative endoscopic sphincterotomy ( P < 0.002), need pre-operative insertion of a ductal stent ( P < 0.03), and had more postoperative complications ( P = 0.04). Patients in the late laparoscopic cholecystectomy group had more comorbidities and suffered more complications.

Patient-reported outcomes (PROs) are essential for patient-centered health care. This pilot study implemented a mobile application customized to an hepatopancreatobiliary Enhanced Recovery After Surgery (ERAS®) program—a novel environment—for real-time collection of PROs, including ERAS® pathway compliance. Patients undergoing hepatectomy, distal pancreatectomy, or pancreaticoduodenectomy through the ERAS® program were prospectively enrolled over 10 months. The application provided education and questionnaires before surgery through 30 days postdischarge. Thresholds were set for initial adoption of the application (75%), PRO response rate (50%), and patient satisfaction (75%). Daily postdischarge health checks integrated customized responses to guide out-of-hospital care. Of 165 enrolled patients, 122 met inclusion criteria. Application adoption was 93 per cent (114/122) and in-hospital engagement remained high at 88 per cent (107/122). Patients completed 62 per cent of PRO on quality of life, postoperative pain, nausea, opioid consumption, and compliance to ERAS® pathway items, including ambulation and breathing exercises. During postcharge tracking, 12 patients reported that the application prevented a phone call to the hospital and three patients reported prevention of an emergency room visit. PRO collection through this mobile device created an integrated platform for comprehensive perioperative care, patient-initiated outcome tracking with automatic reporting, and real-time feedback for process change. Improving proactive outpatient management of complex patients through mobile technology could help restructure health-care delivery and improve resource utilization for all patients.

Published: June 2020

The extended focused assessment with sonography for trauma (eFAST) ultrasound examination is an essential step in the initial assessment of trauma patients. Its accuracy depends on the ability to acquire high-quality ultrasound images, and we hypothesized that increasing BMI was associated with increased odds for incorrect eFAST. All adult blunt trauma activations at a high-volume urban trauma center in 2016 that underwent eFAST and CT chest, abdomen, and pelvis were included (n = 446). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the eFAST were calculated with CT results as reference. The association of BMI and eFAST accuracy was determined using univariate analyses. Sensitivity and specificity of the eFASTexamination were 27.1 per cent and 91.7 per cent, respectively, with an overall 76.2 per cent accuracy. At BMI 36 kg/m2, the odds of having incorrect eFAST results increased to odds ratio (OR) = 1.85 (95% confidence interval, 1.03–3.32; P = 0.05). For those with BMI > 40 kg/m2, the OR increased to OR = 3.12 (95% confidence interval, 1.45–6.69; P = 0.01). One-third of patients in this study were obese or morbidly obese. The latter was associated with increased odds for incorrect eFAST results, particularly the abdominal examination component.

Published: June 2020

Radiologic indicators of sarcopenia have been associated with adverse operative outcomes in some surgical populations. This study assesses the association of radiologic indicators of frailty with outcomes after open ventral hernia repair (OVHR). A prospective, institutional, herniaspecific database was queried for patients undergoing OVHR from 2007 to 2018 with preoperative CT. Psoas muscle cross-sectional area at L3 was measured and adjusted for height (skeletal muscle index (SMI)). L3 vertebral body density (L3 VBD) was measured. Demographics and outcomes were evaluated as related to SMI and L3 VBD. Of 1178 patients, 9.7 per cent of females and 15.8 per cent of males had sarcopenia and 11.6 per cent of females and 9.2 per cent of males had osteopenia. Neither sarcopenia nor osteopenia were associated with outcomes of wound infection, read-mission, reoperation, hernia recurrence, or major complications. When examined as continuous variables or by quartile, SMI and L3 VBD were not associated with adverse outcomes, including in subsets of male or female patients, the elderly, contaminated cases, and the obese. Radiologic markers of sarcopenia and osteopenia are not associated with adverse outcomes after OVHR. Further study should examine age or other potential predictors of outcomes in this patient population, such as independent status.

Hospitalizations for peptic ulcer disease (PUD) have decreased since the advent of specific medical therapy in the 1980s. The authors’ clinical experience at a tertiary center, however, has been that procedures to treat PUD complications have not declined. This study tested the hypothesis that despite decreases in PUD hospitalizations, the volume of procedures for PUD complications has remained consistent. The study population included all inpatient encounters in the state of Maryland from 2009 to 2014 with a primary ICD-9 diagnosis code for PUD. Data on annual patient volume, demographics, anatomic location, procedures, complications, and outcomes were collected, and PUD prevalence rates were calculated. The study population consisted of the state's entire population, not a sample; statistical analysis was not applied. Hospitalizations for PUD declined from 2,502 in 2009 to 2,101 in 2014, whereas the percentage of hospitalizations with procedures increased from 27.1 to 31.5 per cent. Endoscopy was performed in 19.8 per cent of hospitalizations, operation in 9.4 per cent, and angiography in 1.3 per cent. Of 13,974 inpatient encounters, 30 per cent had at least one inhospital complication. Overall inpatient mortality was 2.2 per cent. PUD hospitalizations are declining in Maryland, mirroring national trends. A subset of patients continue to need urgent procedures for PUD complications, including nearly 10 per cent needing operation. Inpatient mortality among patients admitted for PUD was 2.2 per cent, congruent with other studies. Despite the efficacy of modern medical therapy, these data underscore the importance of teaching surgical residents the cognitive and operative skills necessary to manage PUD complications.

Regionalization of complex surgical care has increased interhospital transfers to quaternary centers within large health-care systems. Risk-based patient selection is imperative to improve resource allocation without compromising care. This study aimed to develop predictive models for identifying low-risk patients for transfer to a fully integrated satellite hepatopancreatobiliary (HPB) service in the northeast region of the health-care system. HPB transfers to the quaternary center over 15 months from hospitals in proximity to the satellite HPB center. A predictive tool was developed based on simple pretransfer variables and outcomes for 30-day major complications (Clavien grade ≥ 3), readmission, and mortality. Thresholds for “low risk” were set at different SDs below mean for each model. Predictive models were developed from 51 eligible northeast region patient transfers for major complications (Brier score 0.1948, receiver operator characteristic (ROC) 0.7123, P = 0.0009), readmission (Brier score 0.0615, ROC 0.7368, P = 0.0020), and mortality (Brier score 0.0943, ROC 0.7989, P = 0.0023). Thresholds set from 2 SD below the mean for all models identified 2 as “low risk.” Adjusting the threshold for the serious complication model to only 1 SD below the mean increased the “low-risk” cohort to five patients. These models demonstrate an easy-to-use tool to assist surgeons in identifying low-risk patients for diversion to a fully integrated satellite center. Improved interhospital transfers within a region could begin a transition from centers of excellence toward health-care systems of excellence.
Through Thick or Thin: Disparities in Perioperative Anticoagulant Use in Trauma Patients
Authors: Romagnoli Anna , Dubose Joseph , Feliciano David
Published: June 2020

Although vascular surgery guidelines recommend immediate anticoagulation for acute occlusion of a peripheral artery, it is unclear whether trauma surgeons follow this practice. A survey regarding the use of perioperative anticoagulation was sent to surgeons who perform their own peripheral arterial repairs after traumatic injury to define contemporary practice patterns. This survey demonstrated minimal consensus opinion regarding the management of extremity vascular injuries, strongly suggesting the need for a consensus conference, meta-analysis, and prospective studies to guide further care.

Published: June 2020

As minimally invasive operations evolve, it is imperative to evaluate the advantages and risks involved. The aim of our study was to evaluate our institution's experience in incorporating a robotic platform for transhiatal esophagectomy (THE). Patients undergoing robotic THE were prospectively followed. Data are presented as median (mean ± SD). Forty-five patients were of 67 (67 ± 6.9) years and BMI 26 (27 ± 5.5) kg/m2. Nine per cent of operations were converted to “open,” but none in the last 25 operations. Operative duration of robotic THE was 334 (364 ± 108.8) minutes and estimated blood loss was 200 (217 ± 144.0) mL, which decreased with time ( P = 0.017). Length of stay was 8 (12 ± 11.1) days. Twenty per cent had respiratory failure requiring intubation that resolved, 4 per cent developed pneumonia, 11 per cent developed a surgical site infection, 2 per cent developed renal insufficiency, and 2 per cent developed a UTI. Two per cent (one patient) died within 30 days postoperatively, because of cardiac arrest. Our experience with robotic THE promotes robotic application because we endeavor to achieve high-level proficiency. With experience, we improved estimated blood loss and converted fewer transhiatal esophagectomies to “open.” Our length of hospital stay seems long but reflects the ill-health of patients, as does the variety of complications. Our data support the evolving future of THE, which will integrally include a robotic approach.

Trauma is a time-critical condition. Helicopters are thought to enhance the accessibility to trauma centers, but this benefit is poorly quantified. The aim of this study was to conduct a geographical analysis of the added benefit provided by helicopters, over ground transport. This study uses geospatial analysis. Helicopter bases and Level I and II designated trauma centers were geocoded. 60-minute drive-time and elliptical flight-time isochrones were mapped with ArcGIS™ (Esri, Redlands, CA). Calculations included allowance for mission ground time (MGT). We compared the proportion of the population that could be taken to Level I and II trauma centers, within 60 minutes, by road and by air. Using a 30-minute MGT model, helicopters permit 279,317 additional residents (5.8%) access to a Level I trauma center within 60 minutes. Using the 20-minute MGT model, 1,089,177 more residents (22.8%) would have access to Level I trauma center care. The benefits were marginally greater for access to Level I and II trauma center care. Helicopters enhance access to specialist trauma center care, but the benefit is small and dependent on MGT. Consideration should be given to the siting of helicopters, particularly in relation to trauma patients, MGT, and the timely response of EMS when determining the triage for helicopter transport.

Published: June 2020

Despite aggressive limb salvage techniques, lower extremity amputation (LEA) is frequently performed. Major indications for LEA include ischemia and uncontrolled infection (UI). A review of the national Vascular Quality Initiative amputation registry was performed to analyze the influence of indication on outcomes after LEA. Retrospective review of the Vascular Quality Initiative LEA registry (2012–2017) identified all above- and below-knee amputations. Outcome measures included 30-day mortality, return to operating room (OR), postoperative myocardial infarctions, and postoperative SSI. Indications for surgery included ischemic rest pain, ischemic tissue loss (TL), acute limb ischemia (ALI), UI, and neuropathic TL. A total of 6701 patients met the inclusion criteria. The indications for surgery included TL (49.0%), UI (31.7%), ALI (8.0%), rest pain (6.6%), and neuropathic TL (2.3%). Patients with ALI had the highest 30-day mortality (12.0%) compared with TL (6.6%) and UI (6.4%) [ P < 0.001]. The highest rate of return to OR occurred in the UI group (12.6%) [ P < 0.001]. Multivariate analysis demonstrated that patients with UI have significantly higher rates of return to OR, whereas those with ALI have a 30-day mortality twice as high as other indications (both P < 0.001). These data can inform expectations after LEA based on the indications for surgery.

Prospective randomized studies have demonstrated a survival benefit of immunotherapy in stage IV cutaneous melanoma. Some retrospective studies have hypothesized a synergistic effect of radiation and immunotherapy. Our objective was to identify whether there is a survival benefit for patients treated with radiation and immunotherapy in stage IV cutaneous melanoma of the head and neck (CMHN). The National Cancer Database was used to identify patients with stage IV CMHN between 2012 and 2014. These patients were stratified based on receipt of radiation and immunotherapy. Adjusted Cox regression was used to analyze overall survival. A total of 542 patients were identified with stage IV CMHN, of whom 153 (28%) patients received immunotherapy. Receipt of immunotherapy (hazard ratio [HR] 0.69, P = 0.02) and negative LNs (HR 0.50, P = 0.002) were independently associated with improved survival, whereas radiation conferred no survival benefit (HR 1.17, P = 0.26). Patients who received immunotherapy without radiation were associated with significantly improved survival compared with those who received immunotherapy with radiation ( P < 0.0001). However, of patients who received radiation, the addition of immunotherapy did not seem to improve survival ( P = 0.979). In stage IV CMHN, immunotherapy confers a 32 per cent survival benefit. The use of immunotherapy in patients who require radiation, however, is not associated with improved survival.

Published: June 2020

Youth and young adult interpersonal violence (IPV) is a unique clinical challenge which merits study. This study defined the demographics and clinical outcomes of youth and young adult victims of IPV presenting to our hospital while examining violent injury recidivism. We reviewed patients aged 10 to 30 years admitted to our trauma bay as a victim of gunshot wound (GSW), stabbing wound, or blunt assault from 1998 to 2015 (n = 12,549). Logistic regression analysis was conducted to compare patient mortality across demographic characteristics, and Cox proportional hazards regression was used to determine risk factors for recidivism. Male (92%) and Hispanic patients (75%) constituted the majority of admissions. We observed differences in the mortality rate by gender (9% in males vs 5% in females, P < 0.001), race/ethnicity (5% non-Hispanic white vs 9% Hispanic, P = 0.001), insurance status (3% insured vs 10% uninsured, P < 0.001), and mechanism of injury (13% GSW, 2% stabbing wound, and 0.3% blunt assault, P < 0.001). Male gender, younger age, GSW, and amphetamine placed patients at higher risk for IPV recidivism ( P < 0.05). This study demonstrates the need to better understand how demographics and economics are associated with youth and young adult IPV. In addition, future IPV prevention and intervention initiatives can be tailored to suit the unique needs of our population.

Published: June 2020

Early surgical intervention decreases mortality in necrotizing soft tissue infections (NSTIs). Yet, a subset of patients will not have NSTIs (non-NSTIs) at the time of exploration. We hypothesized that NSTI and non-NSTI patients had similar causative organisms and that intraoperative wound cultures could help guide management. Culture results and outcomes were compared for all patients undergoing surgery for suspected NSTIs over a seven-year-period. Of 295 patients, 240 (81.4%) had NSTIs. Of the 55 non-NSTI patients (18.6%), 50 had cellulitis and 5 had abscesses. NSTI and non-NSTI patients had similar rates of bacteremia (20.4% vs 17.6%, P = 0.66), septic shock (15.9% vs 12.7%, P = 0.68), and mortality (10.4% vs 7.2%, P = 0.62). Wound cultures were collected more often in NSTI patients (229/240, 95.4%) than in non-NSTI patients (42/55, 76.4%, P < 0.01). Non-NSTI patients had positive deep wound cultures more than half of the time (23/42, 54.8%). The microbiologic profile was similar between groups, with Methicillin Resistant Staphylococcus aureus and Group A Streptococcus occurring with the same frequency. We advocate for deep wound cultures in all patients being evaluated operatively for NSTIs even if the exploration is considered negative because these patients have similar clinical characteristics and virulent microbiology, and culture results can help guide antimicrobial therapy.

Published: June 2020

Our department has a database of thoracic gunshot wounds (GSWs), which has cataloged these injury patterns over the past five decades. Prevailing wisdom on the management of these injuries suggested operative treatment beyond tube thoracostomy is not commonly required. It was our clinical impression that the operative treatment required beyond chest tube placement has greatly increased over the past several decades, whereas the operative management of cardiac GSWs seemed to be increasingly infrequent events. To test these observations, we analyzed the treatment of GSWs to the chest and heart in four distinct time periods, categorized as “historical” (1973–1975 and 1988–1990) and “modern” (2005–2007 and 2015–2017). There was a significant increase in emergent thoracotomy, delayed thoracic operations, overall operative interventions, and pulmonary resections from the historical period to the modern era. There was a decline in cardiac injuries treated, whereas the number of injuries remained constant. Mortality was unchanged between the early and later periods. Operative treatment beyond tube thoracostomy was much more prevalent for noncardiac thoracic GSWs in the past two decades than in the prior decades, whereas the number of cardiac wounds treated decreased by half.
Risk of Perforation in the Era of Nonemergent Management for Acute Appendicitis
Authors: Westfall Kristen M. , Charles Anthony G.
Published: June 2020

Prompt appendectomy has long been the standard of care for acute appendicitis because of the risk of progression to perforation. Recently, studies have suggested nonemergent management of acute appendicitis. Our study aimed to determine changes in risk of rupture and complications in patients with appendicitis, with increasing time from symptom onset to treatment. Retrospective study of patients aged ≥18 years presenting to the University of North Carolina Hospitals with signs and symptoms of acute appendicitis who subsequently underwent appendectomy from 2011 to 2015 was performed. Demographic, clinical, laboratory, and pathologic data were reviewed. Bivariate analysis was performed to assess variables associated with increased risk of perforation. Poisson regression modeling was completed to evaluate the risk of perforation and postoperative abscess based on time from symptoms to treatment. Within our database of 1007 patients, the mean time from onset of symptoms to operative intervention was 3.24 ± 2.2 days. Modified Poisson regression modeling demonstrated the relative risk for perforation increases by 9% (RR 1.09, P < 0.001) for each day delay. Age (RR 1.03), male gender (RR 1.50), temperature on admission (RR 1.32), and the presence of fecalith (RR 1.89) statistically significantly increased the risk of perforation. Furthermore, for each day delay, there is an 8% increased risk of postoperative abscess (RR 1.08, P = 0.027). The relative risk for appendiceal perforation is 9 per cent per day delay with a resultant 8 per cent increased risk of postoperative abscess. Thus, appendectomy for acute appendicitis should remain an emergent procedure, given that delays in operative management lead to complications and increases in cost of care.

The best method for fascial closure during hernia repair remains unknown. This study evaluates the impact of fascial closure techniques on short-term outcomes. All patients undergoing open ventral hernia repair were queried using the Americas Hernia Society Quality Collaborative database. Analysis was stratified by suture type (absorbable and permanent) and technique (figure-of-eight, running, and interrupted). Outcome measures included SSI, surgical site occurrence (SSO), SSO requiring intervention, recurrence rate, and quality of life. Descriptive statistics and logistic regression were used. The study included 6544 patients. Two-thirds of surgeons closed fascia during ventral hernia repair with absorbable suture and one-third with permanent suture. In the absorbable group, 17 per cent used figure-of-eight, 46 per cent running, and 4 per cent interrupted suture. In the permanent group, 13 per cent used figure-of-eight, 8 per cent running, and 11 per cent interrupted suture. There was no significant association between SSO and closure technique ( P = 0.2). However, SSO and suture type were significant ( P < 0.001) with the odds of SSO for closure with absorbable suture being 62 per cent higher than the odds of permanent. Fascial closure technique and suture type had no significant association ( P > 0.5) with SSI, SSO requiring intervention, hernia recurrence rate, or HerQLes or NIH PROMIS 3a scores at 30 days or 6 months. Fascial closure technique and suture material do not have a major impact on outcomes in ventral hernia repair. Despite a significantly higher rate of SSO for absorbable sutures than permanent, this did not increase the rate of interventions.

When endoscopy is performed for acute GI bleeding, therapeutic endoscopic procedures are infrequently required (only 6% of cases). We sought to determine the natural history of GI hemorrhage in patients who have undergone therapeutic endoscopy. We queried our hospital database for inpatients with acute GI bleeding who underwent therapeutic endoscopy between 2015 and 2017. The primary endpoints were recurrence of bleeding and the subsequent need for repeated endoscopic interventions, angioembolization, or surgery. Demographic information was collected. We reviewed 205 hospitalized patients: mean age was 70 years, 58 per cent were male, and mean hemoglobin was 9 g/dL. Patients had medical conditions predisposing them to bleeding in 59 per cent and history of previous GI bleeding in 37 per cent of cases. Sixty per cent were on antiplatelet/ anticoagulation medications, and 10 per cent were receiving nonsteroidal anti-inflammatory medications. Blood transfusions were given to 78 per cent of patients, with an average of 2.3 units of packed red blood cells transfused per patient before intervention. Recurrence of hemorrhage after therapeutic endoscopy was seen in 9 per cent of patients. Only 2 per cent underwent a second therapeutic endoscopic procedure, and 5 per cent had surgery or angioembolization (half of these patients then had a further recurrence of bleeding). In total, seven patients died (3%). Recurrence of GI bleeding after therapeutic endoscopies is uncommon (9%). Surgery and angioembolization are not commonly necessary, but when used are only successful in 50 per cent of cases.

Subcutaneous endoscopically assisted ligation (SEAL) technique is an effective and minimally invasive approach for indirect inguinal hernia repair in children. Not all patients are candidates for SEAL because of technical limitations. We hypothesized that preoperatively assessed patient-level factors may predict technical feasibility of SEAL repair. We performed a retrospective review of all patients who underwent indirect inguinal hernia repair between June 2012 and December 2014. All patients younger than two years and any patient older than two years who had a concomitant umbilical hernia were considered candidates for diagnostic laparoscopy with SEAL repair. We compared patients who had SEAL repair with those who had diagnostic laparoscopy with conversion to open repair. Univariate statistics was performed using the chi-squared and Student's t test. One hundred forty-one patients underwent diagnostic laparoscopy with intent to perform a SEAL repair. Seventeen patients were lost to follow-up. Of the remaining 124 patients, 66 had SEAL repairs, 35 had open repairs, and 23 had a SEAL repair with contralateral open repair. Patient age, BMI, gender, history of prematurity, and history of incarcerated hernia were similar between the SEAL and open groups. Sixty-two per cent of hernias were able to be repaired with SEAL technique. Hernia recurrence was seen in 3 of 123 total SEAL repairs and in 1 of 74 open repairs. The recurrence rate for SEAL repairs (2.4%) was not significantly different from the recurrence rate for open repairs (1.4%). No preoperative patient-level factors predicted technical inability to perform a successful SEAL repair. In this series, the recurrence risk of SEAL compared with open repair was low and not statistically significant. For practitioners with minimally invasive experience, SEAL should be considered a safe and successful option for inguinal hernia repair in pediatric patients undergoing routine diagnostic laparoscopy.

Published: June 2020

We investigated whether laryngoscopy should be performed before total thyroidectomy on all patients without a history of neck surgery. A total of 2523 patients who underwent total thyroidectomy between January 1, 2013, and March 18, 2018, were retrospectively examined. Pre-operative vocal cord examination was performed on 2070 of these patients by the otorhinolaryngology department using indirect laryngoscopy. Patients with a history of neck or thyroid surgery were not included in the study. The patients were evaluated in terms of age, gender, symptom (hoarseness/dyspnea), comorbidity, surgical history, biopsy, nodule diameter, pathological diagnosis, and tracheal deviation. Preoperative vocal cord paralysis was detected in 0.8 per cent of the patients (17/2070). Four patients (23.5%) were male and 13 patients (76.5%) were female. The mean age was 62 (range, 25–82) years. Seven of the 17 patients (41%) were symptomatic, with complaints of dyspnea in five and hoarseness in two. The univariate analysis revealed that a nodule diameter >30 mm and the presence of dyspnea were associated with vocal cord damage. Furthermore, the multivariate analysis showed that dyspnea alone was an independent variable ( P = 0.011). It is recommended that preoperative vocal cord evaluation should be performed only in patients with severe symptoms, such as dyspnea.

Hiatal hernia repair (HHR) and fundoplication are similarly performed among all hiatal hernia types with similar techniques. This study evaluates the effect of HHR using a standardized technique for cruroplasty with a reinforcing polyglycolic acid and trimethylene carbonate mesh (PGA/TMC) on patient symptoms and outcomes. A retrospective review of patient perioperative characteristics and postoperative outcomes was conducted for cases of laparoscopic hiatal hernia repair (LHHR) using a PGA/TMC mesh performed over 21 months. Gastroesophageal reflux disease symptom questionnaire responses were compared between preoperative and three postoperative time points. Ninety-six patients underwent LHHR with a PGA/TMC mesh. Post-operatively, the number of overall symptoms reported by patients decreased across all postoperative periods ( P < 0.001). Patients reported a significant reduction in antacid use long term ( P < 0.001). Laryngeal and regurgitation symptoms decreased at all time points ( P < 0.05). There was no difference in dysphagia preoperatively and postoperatively at any time point. Individuals undergoing HHR with PGA/TMC mesh experienced improved regurgitation and laryngeal symptoms, and decreased use of antacid medication.
In Close Combat: Vice-Admiral Lord Horatio Nelson's Injuries in the Napoleonic Wars

Born in Norfolk, England, on September 29, 1758, Horatio Nelson was the sixth of eleven children in a working-class family. With the help of his uncle, Maurice Suckling, a captain in the Royal Navy, Nelson began his naval career as a 13-year-old midshipman on the British battleship Raisonnable. His courage and leadership in the battle marked him for promotion, and he rose quickly from midshipman to admiral, serving in the West Indies, East Indies, North America, Europe, and even the Arctic. As his rank ascended, Nelson's consistent strategy was close engagement, an approach that led to success in combat but placed him in direct danger. Thus, Britain's greatest warrior was also her most famous patient: Nelson suffered more injuries and underwent more operations than any other flag officer in Royal Navy history. His career reached a climax off Cape Trafalgar, where he not only led the Royal Navy to victory over the combined French and Spanish fleets but also met his own death.

The practical component of the Advanced Trauma Life Support (ATLS®) course typically includes a TraumaMan® manikin. This manikin is expensive; hence, a low-cost alternative (SurgeMan®) was developed in Brazil. Our primary objective was to compare user satisfaction among Surge-Man, TraumaMan, and porcine models during the course. Our secondary objective was to determine the user satisfaction scores for SurgeMan. This study included 36 ATLS students and nine instructors (4:1 ratio). Tube thoracostomy, cricothyroidotomy, pericardiocentesis, and diagnostic peritoneal lavage were performed on all the three models. The participants then rated their satisfaction both after each activity and after the course. The porcine and TraumaMan models fared better than SurgeMan for all skills except pericardiocentesis. In the absence of ethical or financial constraints, 58 per cent of the students and 66 per cent of the instructors indicated preference for the porcine model. When ethical and financial factors were considered, no preference was evident among the students, whereas 66 per cent of instructors preferred SurgeMan over the others. The students gave all three models an overall adequacy rating of >80 per cent; the instructors gave only the animal models an adequacy rating of <80 per cent. Although the users were more satisfied with TraumaMan than with SurgeMan, both were considered acceptable for the ATLS course.

The objective of the study was to determine the long-term stricture rate of hepaticojejunostiomy (HJ) performed for benign disease, to compare stricture rates for transplant patients and non-transplant patients, and to compare the success rates of procedural and surgical treatment options. Hospital charts of 135 consecutive patients undergoing HJ between 1998 and 2016 were analyzed retrospectively. The primary outcome was stricture formation. Secondary outcomes were time to stricture diagnosis and success rates of various interventions. The anastomotic stricture rate was 13.3 per cent (18). The mean follow-up period was 4.3 years. The mean time to stricture diagnosis was 2.3 years. Stricture rates were similar between the transplant (19.2%) and nontransplant, non-Whipple group (13%). Strictures were treated with radiological intervention with a 44.4 per cent success rate; each required multiple interventions. Mortality from liver disease after failure of nonoperative management of HJ strictures reached 30 per cent (3). Five of ten patients who failed radiological intervention underwent HJ revision; the success rate was 80 per cent. Anastomotic strictures of HJ performed for benign disease occur in 13 per cent of patients and typically develop within 2.5 years postoperatively. Yet, given the dangerous sequelae of chronic biliary obstruction and potential delay in presentation, a follow-up is recommended for up to 10 years. When strictures occur, HJ revision should be considered early, after two failed radiological interventions.
