RESUMEN
BACKGROUND: Rapid weight loss after bariatric surgery is a risk factor for gallstone development. Numerous studies have shown that ursodiol after surgery decreases rates of gallstone formation and cholecystitis. Real-world prescribing practices are unknown. This study aimed to examine prescription patterns for ursodiol and reassess its impact on gallstone disease using a large administrative database. METHODS: The Mariner database (PearlDiver, Inc.) was queried using Current Procedural Terminology codes for Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between 2011 and 2020. Only patients with International Classification of Disease codes for obesity were included. Patients with pre-operative gallstone disease were excluded. The primary outcome was gallstone disease within 1 year, which was compared between patients who did and did not receive an ursodiol prescription. Prescription patterns were also analyzed. RESULTS: Three hundred sixty-five thousand five hundred patients fulfilled inclusion criteria. Twenty-eight thousand seventy-five (7.7%) patients were prescribed ursodiol. There was a statistically significant difference in development of gallstones (p < 0.001), development of cholecystitis (p = .049), and undergoing cholecystectomy (p < 0.001). There was a statistically significant decrease in the adjusted odds ratio (aOR) for the development of gallstones (aOR 0.81, 95% CI: 0.74, 0.89), development of cholecystitis (aOR 0.59, 95% CI: 0.36, 0.91), and undergoing cholecystectomy (aOR 0.75, 95% CI: 0.69, 0.81). CONCLUSION: Ursodiol significantly decreases the odds of development of gallstones, cholecystitis, or cholecystectomy within 1 year following bariatric surgery. These trends hold true when analyzing RYGB and SG separately. Despite the benefit of ursodiol, only 10% of patients received an ursodiol prescription postoperatively in 2020.

BACKGROUND/PURPOSE: Despite evidence supporting short course outpatient antibiotic treatment following appendectomy for perforated appendicitis, evidence of real-world implementation and consensus for antibiotic choice is lacking. We therefore aimed to compare outpatient antibiotic treatment regimens in a national cohort. METHODS: We identified children who underwent surgery for perforated appendicitis between 2010 and 2018 using the PearlDiver database and compared 45-day disease-specific readmission between children who received shortened (5-8 days) versus prolonged (10-14 day) total antibiotic courses (inpatient intravenous and/or oral) completed with outpatient Amoxicillin/Clavulanate versus Ciprofloxacin/Metronidazole, and compared antibiotic type (5-14 days) to each other. RESULTS: 4916 children were identified, 2001 (90.0%) treated with Amoxicillin/Clavulanate (5-14 days), 381 (19.0%) with shortened (5-8 days), 1464 (73.2%) with prolonged (10-14 days) courses. 222 (10.0%) were treated with Ciprofloxacin/Metronidazole, 44 (19.8%) with shortened, 174 (78.4%) with prolonged courses. Freedom from readmission was not different between prolonged and shortened course whether they received Amoxicillin/Clavulanate (adjusted hazard ratio [AHR] 1.54, 95%CI 0.95-2.5) or Ciprofloxacin/Metronidazole (AHR 3.49, 95%CI 0.45-27.3). Antibiotic type did not affect readmission rate (Amoxicillin/Clavulanate versus Ciprofloxacin/Metronidazole, AHR 1.21, 95%CI 0.71-2.05). CONCLUSION: Prolonged antibiotic regimens are routinely prescribed despite evidence suggesting shorter courses and antibiotic choice are not associated with greater treatment failure. As it is better tolerated, we recommend a shortened course of Amoxicillin/Clavulanate for oral management of perforated appendicitis. STUDY DESIGN: Retrospective. LEVEL OF EVIDENCE: Level III.

Intussusception is the most common cause of bowel obstruction in infants four to ten months old and is commonly idiopathic or attributed to lymphoid hyperplasia. Our patient was a 7-month-old male who presented with two weeks of intermittent abdominal pain associated with crying, fist clenching and grimacing. Ultrasound demonstrated an ileocolic intussusception in the right abdomen. Symptoms resolved after contrast enemas, and he was discharged home. He re-presented similarly the next day and was found to be COVID-19 positive. Computed tomography scan demonstrated a left upper quadrant ileal-ileal intussusception. His symptoms spontaneously resolved, and he was discharged home. This suggests that COVID-19 may be a cause of intussusception in infants, and infants presenting with intussusception should be screened for this virus. Additionally, recurrence may happen days later at different intestinal locations. Caregiver education upon discharge is key to monitor for recurrence and need to return.

BACKGROUND: Previous disparities research has demonstrated that underrepresented racial minority patients have worse colorectal cancer outcomes and that they experience unnecessary delays in time to treatment. These delays may explain worse colorectal cancer outcomes for minority patients and serve as a marker of inequalities in our healthcare system. OBJECTIVE: This study aims to quantify the mechanisms that contribute to this disparity in treatment delay. DESIGN: This is a retrospective analysis of colorectal cancer patients who underwent elective resection from 2004 to 2017. A causal inference mediation analysis using the counterfactual framework was utilized to estimate the extent to which racial disparities among patient factors explain the racial disparities in time to treatment. Mediators included income, education, comorbidities, insurance, and hospital type. SETTINGS: This study was conducted at hospitals participating in the National Cancer Database. PATIENTS: Stage I-III colorectal cancer patients, ≥18 years old, who underwent elective resection from 2004 through 2017 were included. MAIN OUTCOMES MEASURES: The primary measures were indirect effects of mediators between race and delayed time to treatment. RESULTS: Of the 504,405 patients (370,051 colon and 134,354 rectal), 10%, 5%, and 4% were black, Hispanic, and other. In multivariable models, compared to white patients, these patients had 25%, 27%, and 17% greater odds of delayed treatment. Mediation analyses suggested that 43%, 20%, and 31% of the treatment delay among them could be removed if an intervention equalized income, education, comorbidities, insurance, and hospital type to that of white patients. Treatment at an academic hospital explained 15% to 32% of the racial disparity and was the most potent mediator. LIMITATIONS: This study was limited by its retrospective design and failure to capture all meaningful mediators. CONCLUSIONS: Black, Hispanic, and other colorectal cancer patients experience treatment delays when compared to white patients. Equalization of the mediators used in this study could reduce treatment delays by 20% to 43% depending on the racial/ethnic group. Future research should identify other causes of racial disparities in treatment delay and intervene accordingly. See Video Abstract at http://links.lww.com/DCR/B871 . FACTORES MEDIADORES ENTRE LA RAZA Y EL TIEMPO HASTA EL TRATAMIENTO EN EL CNCER COLORECTAL: ANTECEDENTES:Investigaciones anteriores sobre disparidades han demostrado que los pacientes de minorías raciales subrepresentados tienen peores resultados de cáncer colorrectal y que experimentan retrasos innecesarios en el tiempo de tratamiento. Estos retrasos pueden explicar los peores resultados del cáncer colorrectal para los pacientes de minorías y servir como un marcador de desigualdades en nuestro sistema de salud.OBJETIVO:Este estudio tiene como objetivo cuantificar los mecanismos que contribuyen a esta disparidad en el retraso del tratamiento.DISEÑO:Este es un análisis retrospectivo de pacientes con cáncer colorrectal que se sometieron a resección electiva entre 2004 y 2017. Se utilizó un análisis de mediación de inferencia causal utilizando el marco contra factual para estimar hasta qué punto las disparidades raciales entre los factores del paciente explican las disparidades raciales en el tiempo hasta el tratamiento. Los mediadores incluyeron ingresos económicos, educación, comorbilidades, seguro médico y tipo de hospital.AJUSTES:Este estudio se realizó en hospitales que participan en la Base de datos nacional del cáncer.PACIENTES:Se incluyeron pacientes con cáncer colorrectal en estadio I-III, ≥18 años, que se sometieron a resección electiva entre 2004 y 2017.PRINCIPALES RESULTADOS MEDIDAS:Las principales mediciones fueron el efecto indirecto de los mediadores entre la raza y el retraso en el tratamiento.RESULTADOS:De los 504,405 pacientes (370,051 de colon, 134,354 rectal), 10%, 5%, 4% eran negros, hispanos, y otros, respectivamente. En modelos multivariables, en comparación con los pacientes blancos, estos pacientes tenían un 25%, 27%, y 17% más de probabilidades de retrasar el tratamiento. Los análisis de medición sugirieron que el 43%, 20%, 31% del retraso del tratamiento entre, respectivamente, podría eliminarse si una intervención igualara los ingresos económicos, la educación, las comorbilidades, el seguro médico y el tipo de hospital a los de los pacientes blancos. El tratamiento en un hospital académico demostró entre el 15% y el 32% de la disparidad racial y fue el mediador más potente.LIMITACIONES:Este estudio estuvo limitado por su diseño retrospectivo; falla en capturar a todos los mediadores significativos.CONCLUSIONES:Los pacientes negros, hispanos y otros con cáncer colorrectal experimentan retrasos en el tratamiento en comparación con los pacientes blancos. La igualación de los mediadores utilizados en este estudio podría reducir los retrasos en el tratamiento en un 20-43%, según el grupo racial / étnico. Las investigaciones futuras deberían identificar otras causas de disparidades raciales en el retraso del tratamiento e intervenir sobre ellas.

Background: Minimally invasive surgery (MIS) is increasingly used for repair of congenital diaphragmatic hernia (CDH). Reported recurrence after MIS repair varies and is limited by short follow-up and low volume. Our objective was to compare recurrence after MIS versus open repair of CDH. Materials and Methods: Infants who underwent CDH repair between 2010 and 2020 were identified using the PearlDiver Mariner database, a national patient claims data set allowing longitudinal follow-up of patients across systems. Kaplan-Meier analysis and Cox proportional hazards regression models were used to evaluate the association of surgical approach (MIS versus open) and use of a patch with time to recurrence while adjusting for comorbidities (congenital heart disease and pulmonary hypertension) and length of stay (LOS). Results: In a cohort of 629 infants, 25.6% (n = 161) underwent MIS repair with a median follow-up of 4.8 years and recurrence rate of 38.6% (n = 243). Rates of recurrence after MIS repair were lower than open (5 years: 38.6% versus 44.3%; P = .03) and higher with use of patch (5 years: 60.1% versus 40.1%; P = .02). After adjustment for comorbidities and LOS as a proxy for patient complexity, there was no significant difference in recurrence based on approach (adjusted hazard ratio [aHR]: 0.79; confidence interval [95% CI]: 0.57-1.10; P = .16) or use of patch (aHR: 1.22; 95% CI: 0.83-1.79; P = .32). Conclusions: Recurrence rates after repair of CDH were not different based on surgical approach or use of patch after adjustment. Previous data were likely biased by patient complexity, and surgeons should consider these factors in determining approach.

BACKGROUND: Optimal inguinal hernia repair timing remains controversial. It remains unclear how COVID-19 related elective surgery cancellations impacted timing of inguinal hernia repair and whether any delays led to complications. This study aims to determine whether elective surgery cancellations are safe in pediatric inguinal hernia. METHODS: This multicenter retrospective cohort study at 14 children's hospitals included patients ≤18 years who underwent inguinal hernia repair between September 13, 2019, through September 13, 2020. Patients were categorized by whether their inguinal hernia repair occurred before or after their hospital's COVID-19 elective surgery cancellation date. Incarceration and emergency department encounters were compared between pre and postcancellation. RESULTS: Of 1,404 patients, 604 (43.0%) underwent inguinal hernia repair during the postcancellation period, 92 (6.6%) experienced incarceration, and 213 (15.2%) had an emergency department encounter. The postcancellation period was not associated with incarceration (odds ratio 1.54; 95% confidence interval 0.88-2.71; P = .13) or emergency department encounters (odds ratio 1.53; 95% confidence interval 0.94-2.48; P = .09) despite longer median times to inguinal hernia repair (precancellation 29 days [interquartile range 13-55 days] versus postcancellation 31 days [interquartile range 14-73 days], P = .01). Infants were more likely to have the emergency department be their index presentation in the postcancellation period (odds ratio 1.69; 95% confidence interval 1.24-2.31; P < .01). CONCLUSION: Overall, COVID-19 elective surgery cancellations do not appear to increase the likelihood of incarceration or emergency department encounters despite delays in inguinal hernia repair, suggesting that cancellations are safe in children with inguinal hernia. Assessment of elective surgery cancellation safety has important implications for health policy.

INTRODUCTION: Recurrent primary spontaneous pneumothorax (PSP) is often managed with a wedge resection (or blebectomy) and either pleurectomy or pleurodesis. There is a conflicting data regarding which approach is superior to reduce recurrence. Our objective is to evaluate the long-term recurrence rates following pleurectomy versus mechanical pleurodesis for recurrent PSP. METHODS: The PearlDiver Mariner Patient Claims Database was queried for patients aged 10-25 who were presented with PSP and underwent either pleurectomy or mechanical pleurodesis between 2010 and 2020. The primary outcome was recurrence and secondary outcomes included 30-day opioid prescriptions, pain diagnoses, and reimbursement. Kaplan-Meier analysis and Cox proportional hazards regression models were used with adjustment for age and sex. RESULTS: Of 18,955 patients presenting with PSP, 5.1% (n = 968) were managed operatively with either pleurectomy (18.3%, n = 177) or mechanical pleurodesis (81.7%, n = 791). There was no difference in the rate of recurrence between pleurectomy and mechanical pleurodesis (5-year risk of recurrence: 25.8% versus 26.5%, adjusted hazard ratio (HR) = 1.12 [95% confidence interval (CI): 0.79, 1.58]). Furthermore, there was no difference in rate of outpatient opioid prescription (49.2% versus 52.8%, P = 0.58) or pain diagnoses (22.0% versus 22.8%, P = 0.46) between pleurectomy and mechanical pleurodesis, respectively. The median reimbursement was higher following pleurectomy as compared to mechanical pleurodesis ($14,040 versus $5,811, P = 0.02). CONCLUSIONS: There is no significant difference in recurrence based on type of procedure performed for recurrent primary spontaneous pneumothorax. However, reimbursement is higher following pleurectomy. Given the similar outcomes but higher cost, we recommend mechanical pleurodesis over pleurectomy for recurrent PSP.

BACKGROUND: Reported recurrence rates after laparoscopic versus open inguinal hernia repair have been limited to high volume centers with short follow-up. We sought to compare national rates of recurrence after laparoscopic versus open bilateral inguinal hernia repair. METHODS: Children under five who underwent bilateral inguinal hernia repair between 2010 and 2020 were identified using the PearlDiver Mariner database. Time to recurrence was compared using Kaplan Meier analysis and Cox proportional hazards regression models. RESULTS: Hernia recurrence requiring reoperation occurred in 182 (2.2%) of 8,367 children. Rate of recurrence was higher following laparoscopic repair compared to open (1-year: 2.8% vs. 1.5%; 3-year: 3.7% vs. 2.0%; p < 0.01). This difference remained after adjustment for demographic and operative characteristics (adjusted hazard ratio [aHR]: 2.00 [95% confidence interval [CI]: 1.31, 3.05]). CONCLUSIONS: Risk of recurrence was higher after laparoscopic compared to open repair of bilateral inguinal hernia repair in a national cohort of children under age five.

BACKGROUND: Limited in-person visits during the COVID-19 pandemic, with liberal reimbursement policies, resulted in increased use of video conferencing (hereby described as telehealth) for patient care. To better understand the impact on pediatric surgeons and their patients, we surveyed members of the American Pediatric Surgical Association (APSA) regarding telehealth use prior to and during the pandemic. METHODS: An iteratively developed survey was sent to all active, non-trainee surgeons within APSA during March 2021. RESULTS: Of 247 responses (23% response rate), 154 (62%) began using telehealth during the pandemic. In addition to the 101 (60.5%) respondents who felt telehealth had a positive impact on their clinical practice, 161 (74.2%) felt that it had a positive impact on their patients' satisfaction. The most common barriers to telehealth use prior to COVID-19 were availability of technology (39.3%), patient access to technology (36.0%), and lack of reimbursement (32.0%). These barriers became less substantial during the pandemic. Most respondents (95.3%) indicated they would continue using telehealth post-pandemic if it remains appropriately reimbursed. CONCLUSIONS: The majority of pediatric surgeons implemented telehealth during the COVID-19 pandemic and endorsed a positive effect on their clinical practice as well as on patient satisfaction. An overwhelming majority would continue using this technology if reimbursement policies remain favorable.

BACKGROUND/PURPOSE: Neonatal circumcision is a common pediatric procedure performed in both the inpatient and outpatient setting. We aimed to determine if procedure location affected 30-day post-procedure healthcare utilization rates, inpatient length of stay (LOS), and amount charged. METHODS: We performed a retrospective cohort study comparing 30-day postoperative healthcare utilization (emergency department (ED) visits, office visits, readmissions) of full-term infants who underwent an outpatient versus inpatient (same admission as birth) circumcision from 2015 to 2020. Statistical analyses included Chi-square tests, multivariable adjusted logistic regression models when appropriate. RESULTS: 3137 infants were included, 1426 (45.5%) had an outpatient circumcision, 1711 (54.5%) an inpatient. Outpatient had similar overall healthcare utilization rates as inpatients (5.7% vs. 5.6%, p = 0.933). The number of ED visits (1.5% vs 0.8%, p = 0.055), office visits (4.5% vs. 5.1%, p = 0.437), and readmissions (0.2% vs. 0.0%, p = 0.058) were not significantly different. Infants with inpatient circumcisions had longer LOS after adjusting for age, ethnicity and delivery type (Cesarean versus vaginal) with an incident rate ratio of 1.97 (95% confidence interval 1.84-2.11, p<0.001). Outpatient circumcision resulted in average charges of $372 more than inpatient. CONCLUSIONS: Outpatient circumcision has a minimal effect on healthcare utilization rates but lead to a shorter hospital stay following birth and increased charge.

Neuroblastoma is a common childhood cancer with poor prognosis when at its advanced stage. Checkpoint molecule inhibition is successful in treating multiple advanced adult cancers. We investigated PD-L1 and other checkpoint molecule expression to determine their roles in drug resistance and usefulness as targets for drug therapy. We developed three doxorubicin-resistant (DoxR) cell lines from parental cell lines. Matrigel in vitro invasion assays were used to compare invasiveness. Western blot assays were used to compare PD-L1 expression. Immuno-oncology checkpoint protein panels were used to compare concentrations of 17 checkpoint molecules both cellular and soluble. PD-L1 and 12 other checkpoint molecules were present in all cell lysates of each cell line without significantly different levels. Three were solubilized in the media of each cell line. PD-L1 is expressed in all DoxR and parental neuroblastoma cells and may be a potential target for drug therapy although its role in drug resistance remains unclear. Benchmarking checkpoint molecules provides the basis for future studies identifying targets for directed therapy and biomarkers for cancer detection or prognosis.
RESUMEN
INTRODUCTION: General surgery residents often feel unprepared to perform pediatric surgery procedures since case volume and experience may be low. Previously, we successfully implemented a simulation-based training (SBT) module for placement of a silastic silo for gastroschisis. Therefore, we designed a single institution pilot study to assess whether SBT for placement of a percutaneous peritoneal drain for perforated necrotizing enterocolitis (NEC) was feasible and lead to skill acquisition and increased confidence. METHODS: Our newly created NEC module within our pediatric surgery SBT curriculum for general surgery residents was used. Residents completed two simulation sessions three months apart with confidence testing before and after each session. Skill acquisition and performance were assessed using a standardized case scenario and procedure checklist. Changes in residents' confidence and performance were determined using Wilcoxon Signed-Rank Tests. RESULTS: Nine post-graduate-year three general surgery residents completed this curriculum. Following completion, residents reported improved confidence completing each step of the procedure initially (p = 0.005) and at 3 months (p = 0.008) with improved technical scores (p = 0.011). The number of residents deemed proficient significantly improved (p = 0.031). CONCLUSION: Implementation of SBT module for perforated NEC was feasible and improved residents' confidence and proficiency completing the procedure.

ABSTRACT: Velopharyngeal dysfunction (VPD) is described as the incomplete closure of the velopharyngeal port during a speech production. Nasopharyngoscopy and/or multiplanar videofluoroscopy have been utilized for decades to assess the degree and nature of the dysfunction. Cone-beam computed tomography (CBCT) is presented as an additional diagnostic tool, allowing for clear visualization of the affected structures and the ability to obtain accurate measurements (within 100 microns) of the involved anatomy and defect. This prospective pilot study aims to test the feasibility of using "active-phonation" CBCT to assess suspected VPD in the pediatric and young adult populations and compare the results to nasopharyngoscopy; the current standards of care.Six patients, ages 6 to 26âyears, with suspected VPD, defined as the inability to completely close off the nasal airway during an oral speech, seen at an urban medical outpatient craniofacial care center, served as subjects for this pilot study. Each patient received a comprehensive speech evaluation and participated in both active-phonation CBCT and nasopharyngoscopy.Both active-phonation CBCT and nasopharyngoscopy revealed incomplete closure of the velopharyngeal port during a speech in all 6 patients (100%). Two patients (33%) were unable to tolerate a complete nasendoscopic examination. There was no difference between CBCT or nasopharyngoscopy in determining the presence of VPD and noting the severity on a 3-point scale, (Pâ=â0.61) as judged by 4 experienced clinicians.As a functional imaging modality, active-phonation CBCT is a useful adjunct tool for accurate diagnosis of VPD and may be more easily tolerated during a thorough VPD assessment than nasopharyngoscopy. It also provides quantitative data that is useful to augment treatment optimization and surgical planning in this population. Further studies are needed to validate these results.

BACKGROUND/PURPOSE: Gastrostomy tube (GT) placement is a common pediatric procedure with high postoperative resource utilization. We aimed to determine if standardized discharge instructions (SDI) reduced healthcare utilization rates. METHODS: We performed a retrospective cohort study comparing postoperative hospital utilization of patients who underwent initial GT placement pre- and post-SDI protocol implementation from 2014-2019. Statistical analyses included Chi-square tests, multivariable adjusted logistic regression, adjusted Cox proportion hazard regression, and adjusted Poisson regression models when appropriate. RESULTS: 197 patients were included, 102 (51.8%) before and 95 (48.2%) after protocol implementation. On primary analysis, SDI patients did not have significantly different total postoperative hospital utilization events at 30-days (48.0% vs. 38.9%, p = 0.25). On secondary analysis, SDI patients had lower rates of ED (8.4% vs. 19.6%, p = 0.026) and office visits (11.6% vs. 25.5%, p = 0.017) at 30-days. Non-SDIs patients had greater odds of ED visits (OR2.7, 95%CI 1.3-5.9, p = 0.01), office visits (OR3.7, 95%CI 1.7-8.1, p = 0.001) and phone calls (OR2.6, 95%CI 1.2-5.7, p = 0.016) at 1-year. The adjusted hazard ratio was 2.0 (95%CI 1.4-3.0, p < 0.001). Incident rate ratio were 1.8 (95%CI 1.2-2.5, p = 0.002) at 30-days and 1.9 (95%CI 1.5-2.4, p < 0.001) at 1-year post-discharge. CONCLUSIONS: SDIs post-GT placement may reduce multiple aspects of postoperative hospital utilization.

BACKGROUND/PURPOSE: To assess surgical outcomes of patients with cerebral palsy (CP) and if they differ from patients without CP. METHODS: The NSQIP-Pediatric database from 2012 to 2019 was used to compare differences in presenting characteristics and outcomes between patients with and without CP. Chi-square tests and multivariable logistic regression analysis were used to determine significance. RESULTS: 119,712 patients, 433 (0.4%) with CP, 119,279 (99.6%) without, were identified. Patients with CP had more postoperative complications (19.4% vs. 6.9%, p < 0.001) with an OR of 3.2, (95%CI 2.5-4.1, p < 0.001) on univariable analysis. They underwent fewer laparoscopic procedures (79.1% vs. 90.8%, p < 0.001), had more readmissions (10.2% vs. 3.8%, p < 0.001), reoperations (5.1% vs. 1.2%, p < 0.001), and longer length of stays (LOS) (median 3 versus 1 day, p < 0.001). On multivariable analysis, having CP did not increase the odds of postoperative morbidity (OR 0.99, 95% CI 0.7-1.3), but higher ASA class, congenital lung malformation, gastrointestinal disease, coagulopathy, preoperative inotropic support, oxygen use, nutritional support, and steroid use significantly increase the odds of morbidity, all of which were more common in patients with CP. CONCLUSION: Patients with CP have more postoperative complications, open procedures, and longer LOS. Patient complexity may account for these differences and risk-directed perioperative planning may improve outcomes. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Inhibition of the programmed death ligand 1, programmed death 1 pathway has been successfully used for treatment of multiple advanced adult cancers. However, its use in pediatric osteosarcoma is still in its infancy. In this study, we investigated programmed death ligand 1 and other checkpoint molecules' expression to determine the potential usefulness as targets for drug therapy. METHODS: We incubated human wild-type osteosarcoma cells with incremental concentrations of doxorubicin to create a doxorubicin-resistant cell line. Matrigel in vitro invasion assays were used to compare invasiveness. Comparative programmed death ligand 1 expression was evaluated by Western blot assays. An immuno-oncology checkpoint protein panel was used to compare concentrations of 16 other checkpoint molecules. Chi-square tests and Wilcoxon rank-sum tests were used to determine significant differences. RESULTS: A doxorubicin-resistant cell line was successfully created and was significantly more invasive than wild-type cells (0.47 vs 0.07, P < .001). On Western blot assay, doxorubicin-resistant but not wild-type cells expressed programmed death ligand 1. Doxorubicin-resistant cells had significantly higher levels of T-cell immunoglobulin-3 and cluster of differentiation 86 and higher cluster of differentiation 27, cluster of differentiation 40, lymphocyte-activation gene-3, cluster of differentiation 80, programmed death ligand 1, programmed death ligand 2, and inducible T-cell costimulatory expression than wild-type cells. Both lines expressed B- and T-lymphocyte attenuator, cluster of differentiation 28, herpesvirus entry mediator, and programmed death 1. Herpesvirus entry mediator, cluster of differentiation 40, and programmed death ligand 2 were also present in the culture media of both cell lines. CONCLUSION: Doxorubicin-resistant osteosarcoma seems to express higher programmed death ligand 1 than nonresistant wild-type cells. Benchmarking checkpoint molecules may provide the basis for future studies that elucidate pathways of drug resistance and tumor metastasis, biomarkers for cancer prognosis or recurrence, and future targets for directed drug therapy.
RESUMEN
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.
