RESUMO
OBJECTIVE: Techniques such as the use of nonpenetrating vascular clips for arteriovenous fistula (AVF) anastomotic creation have been developed in an effort to reduce fistula-related complications. However, the outcomes data for the use of clips have remained equivocal, and the cost evaluations to support their use have been largely theoretical. Therefore, the present study aimed to determine both the clinical and the cost outcomes of AVFs created with nonpenetrating vascular clips compared with the continuous suture technique during a 10-year period at a single institution. METHODS: All patients undergoing AVF creation in the upper extremity from 2009 through 2018 were retrospectively analyzed. The patient demographics and AVF outcomes were collected and compared stratified by the surgical technique used. A cost analysis was performed of a subgroup of patients from 2013 to 2018. RESULTS: During the 10-year study period, 916 AVFs were created (79% using the continuous suture technique and 21% using nonpenetrating vascular clips). Patient demographics and comorbid conditions did not differ between the two groups, and no differences were present in maturation, primary patency, assisted primary patency, or complication rates between the two groups at 1 year. The suture group had a shorter time to maturation (4.3 months vs 5.5 months; P < .01) and improved secondary patency compared with the clip group (77.13% vs 69.59%; P = .03) The cost analysis of the procedures revealed a significant difference in direct costs (suture, $1389.26 vs clip, $1716.51; P < .01) and contribution margin (suture, $1770.19 vs clip, $1128.36; P < .01) for the two groups. CONCLUSIONS: Both suture and clip techniques in AVF creation demonstrated equivalent rates of maturation, primary patency, assisted primary patency, and complications at 1 year with higher expense associated with the use of clips. Thus, in an effort to reduce the economic burden of healthcare in the United States, the findings from the present study support the preferential use of the standard polypropylene suture technique when creating upper extremity AVFs.

BACKGROUND: Inequities in breast cancer treatment lead to delay in therapy, decreased survival and lower quality of life. This study aimed to examine demographics and clinical factors impacting time to treatment for second-opinion breast cancer patients. MATERIALS AND METHODS: We performed a retrospective chart review to analyze patients presenting to one academic institution for second opinion of breast imaging, diagnosis, or breast-related treatment. Data from women with stage I-III breast cancer who received treatment at this institution were evaluated to determine the impact of patient demographics and clinical characteristics on time to first treatment. RESULTS: Of the 1006 charts reviewed, 307 met inclusion criteria. Low-income patients averaged 58 days from diagnosis to surgery compared to 35 days for high-income patients (incidence rate ratio [IRR] 0.64, P<0.01). Black patients averaged 56 days from diagnosis to surgery compared to 42 days for White patients (IRR 1.37, P<0.01). Latina patients averaged 38 days from initial encounter to neoadjuvant chemotherapy compared to 20 days for White patients (IRR 1.69, P<0.05). CONCLUSION: Patients with low-income, of Black race and Latina ethnicity experienced increased time to treatment. Additionally, time to mastectomy with and without reconstruction was longer than time to partial mastectomy. Further exploration is needed to determine why certain factors lead to treatment delay and how inequities can be eliminated.

OBJECTIVE: Mycotic aneurysms of the infrapopliteal vessels are rare, with few cases reported in the literature. Management strategies are diverse and should be tailored to the patient's presentation. METHODS: We describe the case of a 40-year-old male who presented with a painful left leg mass in the setting of bacteremia and infective endocarditis. Imaging revealed an aneurysm of the anterior tibial artery. RESULTS: The patient was treated with antibiotics and open surgical repair with excision of the aneurysmal sac, ligation of the anterior tibial artery, and primary repair of the popliteal artery and tibioperoneal trunk. CONCLUSION: The epidemiology, pathophysiology, and clinical management of infrapopliteal aneurysms are briefly reviewed in this case study.

Background: Sebaceous carcinoma is a rare cancer, and little is known about its current epidemiology and treatment. This is particularly true for sebaceous carcinomas of the trunk and extremities. Objective: We present a database analysis of sebaceous carcinoma cases to further delineate demographics, location, tumor characteristics, and treatment modalities among patients diagnosed with these tumors. Methods: The National Cancer Database was queried for cases of sebaceous carcinoma between 2004 and 2016. 3211 cases were analyzed for descriptive and comparative statistics. Results: Twenty-six percent of sebaceous carcinomas were found on the trunk and extremities. Tumors on the trunk and extremities were more likely to be larger than tumors on the head and neck, with 8% being greater than 50 mm (P < .001). Tumors on the trunk and extremities were more likely to be well differentiated (P < .001) and have fewer lymph node metastases (P < .001). Surgery was the primary treatment modality for tumors, followed by radiotherapy and rarely chemotherapy. Conclusions: Sebaceous cancer is a poorly understood entity. We demonstrated that trunk and extremity tumors tend to be larger and more differentiated than those of the head and neck. Treatment practices are varied at this time, but surgery is the primary modality.
RESUMO
BACKGROUND: To compare opioid prescribing practices of resident physicians across a variety of surgical and nonsurgical specialties; to identify factors which influence prescribing practices; and to examine resident utilization of best practice supplemental resources. METHODS: An anonymous survey which assessed prescribing practices was completed by residents from one of several different subspecialties, including internal medicine, obstetrics and gynecology, general surgery, neurosurgery, orthopedic surgery, and urology. Fisher's exact test assessed differences in prescribing practices between specialties. RESULTS: Only 35% of residents reported receiving formal training in safe opioid prescribing. Overall, the most frequently reported influences on prescribing practices were the use of standardized order sets for specific procedures, attending preference, and patient's history of prescribed opioids. Resident physicians significantly underutilize best practice supplemental resources, such as counseling patients on pain expectations prior to prescribing opioid medication; contacting established pain specialists; screening patients for opioid abuse; referring to the Prescription Monitoring Program; and counseling patients on safe disposal of unused pills (P < .001). DISCUSSION: The incorporation of comprehensive prescribing education into resident training and the utilization of standardized order sets can promote safe opioid prescribing.

BACKGROUND: Arteriovenous fistulae (AVF) complicated by aneurysms are repaired through several mechanisms. Little is known about risk factors for aneurysm recurrence or the efficacy of subsequent repair of recurring aneurysms. METHODS: About 291 patients underwent AVF aneurysm repair between 2009 and 2019 at a large urban medical center. Patients who underwent staged repair, had a primary graft with pseudoaneurysm, were status-post kidney transplant, or using other dialysis access at the time of repair were excluded. One hundred sixty-two patients were included in the study, of which 52 developed a secondary aneurysm. Chi-square and t-test analyses were used to compare demographics. Multivariate logistic regression was used to examine independent risk factors for aneurysm recurrence. Of the 52 patients with recurrent aneurysms, 41 were repaired again. Patency was examined for each group 1 year postoperatively. RESULTS: Patients without secondary aneurysms were more likely to have a Charlson Comorbidity Index score ⩾5 (p = 0.045). Males were 2.8 times more likely to develop a secondary aneurysm compared to females (p = 0.023). Patients who underwent elective compared to emergent or urgent surgery for primary aneurysms were significantly less likely to recur (OR = 0.222; p = 0.016). Primary aneurysms repaired by end-to-end anastomosis, compared to aneurysmorrhaphy or graft, were significantly less likely to recur (OR = 0.239; p = 0.041). Among patients with secondary aneurysms, those repaired via end-to-end anastomosis had a significantly higher primary patency rate 1 year postoperatively (p = 0.024). Secondary aneurysm repairs exhibited 1-year primary and secondary patency rates of 51.2% and 82.9%, respectively. CONCLUSIONS: End-to-end anastomosis reduces risk of recurrence and demonstrates superior patency rates when repairing recurrent aneurysms. It remains unclear why some patients are prone to aneurysm recurrence, however continued attempts to repair existing vascular access are proven to be successful.
RESUMO
INTRODUCTION: Arteriovenous fistula (AVF) aneurysms are a chronic complication which can be disfiguring, painful, and can rupture. Here, we compare the outcomes between three different methods of AVF aneurysm repair. METHODS: One-way ANOVA, Chi-square, and Fisher Exact analyses were used to compare demographics. Multivariate logistic regression compared outcomes. Kaplan-Meier estimate illustrated long-term fistula patency. RESULTS: There were no differences between demographics in the aneurysmorrhaphy, end-to-end anastomosis, and synthetic graft groups. The odds of patients who received graft repair losing primary patency within one year compared to the aneurysmorrhaphy group was 3.5 (p = 0.025). Graft repair patients were 6.7 times more likely to develop an infection compared to aneurysmorrhaphy (p = 0.014). Synthetic grafts also exhibited accelerated rates of complete access loss compared to autogenous methods (p = 0.034). CONCLUSIONS: Graft repair of AVF aneurysms results in higher rates of infection and decreased primary and ultimate patency compared to autogenous repair techniques. Therefore, synthetic grafts should be avoided whenever possible.

BACKGROUND: In the United States, few high-quality manuscripts have directly compared the complication profiles of percutaneous endoscopic versus fluoroscopic gastrostomy. Thus, it is our goal to compare these 2 common procedures to better understand their efficacy and complication profiles. MATERIALS AND METHODS: A retrospective analysis of patient records from Medicare parts A/B from 2007 to 2012 was used to identify percutaneous fluoroscopic gastrostomy and percutaneous endoscopic gastrostomy procedures. Patient demographics were stratified by age, sex, comorbidities, and complications. RESULTS: A total of 258,641 patients were found to have either percutaneous fluoroscopic gastrostomy (26,477, 10.2%) or percutaneous endoscopic gastrostomy (232,164, 89.8%). Percutaneous fluoroscopic gastrostomy experienced greater rates for all complications queried. Multivariate analysis revealed that the percutaneous fluoroscopic gastrostomy cohort had statistically significant increased odds for short-term complications, such as ileus (odds ratio 1.4, 95% confidence interval 1.22-1.54), mechanical (odds ratio 2.4, 95% confidence interval 2.28-2.58), wound infection (odds ratio 1.4, 95% confidence interval 1.24-1.52), persistent fistula after tube removal (odds ratio 1.9, 95% confidence interval 1.78-2.12), and other complications (odds ratio 2.2, 95% confidence interval 2.03-2.37), and long-term complications, including abdominal wall pain (odds ratio 1.4, 95% confidence interval 1.33-1.44), wound infection (odds ratio 1.1, 95% confidence interval 1.01-1.15), and persistent fistula after tube removal (odds ratio 1.8, 95% confidence interval 1.72-1.87). CONCLUSION: Gastrostomy tubes are more frequently being placed via percutaneous endoscopic and fluoroscopic methods. This study suggests that those undergoing fluoroscopic placement have higher odds of developing short- and long-term postoperative complications.
RESUMO
BACKGROUND: We aimed to evaluate the long-term complication profile associated with port-a-catheter placement. METHODS: Patients undergoing port-a-catheter placement from 2007 to 2012 with 5-year follow up were identified. Descriptive statistics, χ2 tests, and multivariate regression models were analyzed. RESULTS: Any complication occurring within 5 years postoperatively was common (59.04%, nâ¯=â¯53,353). Arrhythmogenic (32.66%, nâ¯=â¯30,625) and thrombovascular (36.80%, nâ¯=â¯34,499) complications were more common than infection (17.86%, nâ¯=â¯16,745) and mechanical (10.31%, nâ¯=â¯9,670) complications. Multivariate analysis demonstrated that history of atrial fibrillation is a risk factor for developing any complication (odds ratio 7.99, 95% confidence interval 7.29-8.77). CONCLUSION: Patients with history of atrial fibrillation have increased odds of developing infectious, thrombovascular, mechanical, and arrhythmogenic complications with port-a-catheter placement. This study is the first to show that postprocedure arrhythmias occur at significant rates within the 5-year follow-up period. We caution that development of new arrhythmia should be monitored throughout a prolonged follow-up period. We hope our analysis encourages multidisciplinary coordination of patients with ports so that implants are promptly removed when they are no longer needed to avoid these complications.
RESUMO
BACKGROUND Patient compliance with immunosuppressive therapy after transplant has impacts on both graft and patient outcomes. For diabetic end-stage renal disease (ESRD) patients who are undergoing evaluation for kidney transplantation in our program, hemoglobin A1c (HbA1c) level of >10% is used as a flag that the patient may be at risk for noncompliance and that more comprehensive psychosocial screening is needed prior to transplant. We evaluated the association between pre-transplant HbA1c level and post-transplant compliance, as no study to date has looked at this in the transplant population. MATERIAL AND METHODS The charts of 392 patients who received a kidney transplant at a single institution between July 2008 and June 2012 were retrospectively reviewed. One hundred and sixty-five diabetic patients who received a kidney transplant alone were included in the final analysis. Our predictive variable was HbA1c level greater than 7.7% based on previous reports in the diabetic population. Outcome measures were graft survival, rejection episodes, unexplained low immunosuppressant levels, and documented noncompliance. RESULTS There were no statistically significant differences between the HbA1c groups of ≤7.7% and >7.7% in outcomes of failed grafts (22.0% and 17.8%, p=0.2), rejection episodes (15.0% and 6.7%, p=0.3), unexplained low immunosuppressant level (46.6% and 37.9%, p=0.3), and documented noncompliance (25.0% and 16.7%, p=0.4). CONCLUSIONS In diabetic ESRD patients selected for renal transplantation, elevated pre-transplant HbA1c levels, defined as HbA1c >7.7%, are not predictive of post-transplant medication compliance. We advocate that this group of patients should not be denied transplant solely on their elevated pre-transplant HbA1c.

Although >10% of surgical patients receive alternative antibiotic prophylaxis for reported penicillin allergies, it is estimated that <20% of such cases represent true allergies that preclude standard prophylaxis. Each antibiotic class has a distinct impact on the intestinal microbiota and on postoperative metabolomics. The community structure and function of the microbiota are linked to the ability to lose weight after bariatric surgery. This study demonstrates differential weight loss after laparoscopic sleeve gastrectomy between patients who received standard (cefoxitin) and alternative (levofloxacin and metronidazole) perioperative prophylaxis. Multivariate analysis demonstrates that alternative prophylaxis is significantly and independently associated with diminished postoperative weight loss.

BACKGROUND: Low-dose computed tomography (LDCT) scan for lung cancer screening is underutilized. Studies suggest that up to one-third of providers do not know the current lung cancer screening guidelines. Thus, identifying the barriers to utilization of LDCT scan is essential. METHODS: Primary care providers in three different healthcare settings in the United States were surveyed to assess provider knowledge of LDCT scan screening criteria, lung cancer screening practices, and barriers to the utilization of LDCT scan screening. Fisher's Exact, Chi-Squared, and Kruskal-Wallis tests were used to compare provider responses. Multivariable logistic regression was used to test the association between provider characteristics and the likelihood of utilizing LDCT scan for lung cancer screening. RESULTS: The survey was sent to 614 providers, with a 15.7% response rate. Overall, 29.2% of providers report never ordering LDCT scans for eligible patients. Providers practicing at a community or academic hospital more frequently order LDCT scans than those practicing at a safety net hospital. Academic- and community-based providers received a significantly higher mean knowledge score than safety net-based providers [academic 6.84 (SD 1.33), community 6.72 (SD 1.46), safety net 5.85 (SD 1.38); P<0.01]. Overall, only 6.2% of respondents correctly identified all six Centers for Medicare and Medicaid Services eligibility criteria when challenged with three incorrect criteria. Common barriers to utilization of LDCT scan included failure of the electronic medical record (EMR) to notify providers of eligible patients (54.7%), patient refusal (37%), perceived high false-positive rate leading to unnecessary procedures (18.9%), provider time constraints (16.8%), and lack of insurance coverage (13.7%). CONCLUSIONS: Provider knowledge of lung cancer screening guidelines varies, perhaps contributing to underutilization of LDCT scan for lung cancer screening. Improved provider education at safety net hospitals and improving EMR-based best practice alerts may improve the rate of lung cancer screening.
