RESUMO

OBJECTIVE: To understand the variability of surgical attending experience and perspectives regarding informed consent and how it impacts resident education DESIGN: A novel survey was distributed electronically to explore faculty surgeon's personal learning experience, knowledge, clinical practice, teaching preferences and beliefs regarding informed consent. Chi-square and Kruskal-Wallis testing was performed to look for associations and a cluster analysis was performed to elucidate additional patterns among. SETTING: Single, tertiary, university-affiliated health care system (Yale New Haven Health in Connecticut), including 6 teaching hospitals. PARTICIPANTS: Clinical faculty within the Department of Surgery. RESULTS: A total of 85 surgeons responded (49% response rate), representing 17 specialties, both private practice and university and/or hospital-employed, with a range of years in practice. Across all ages, specialties, the most common method for both learning (86%) and teaching (82%) informed consent was observation of the attending. Respondents who stated they learned by observing attendings were more likely to report that they teach by having trainees observe them (OR 8.5, 95% CI 1.3-56.5) and participants who recalled learning by having attendings observe them were more likely to observe their trainees (OR 4.1, 95% CI 1.5-11.2).Cluster analysis revealed 5 different attending phenotypes with significant heterogeneity between groups. A cluster of younger attendings reported the least diverse learning experience and high levels of concern for legal liability and resident competency. They engaged in few strategies for teaching residents. By comparison, the cluster that reported the most diverse learning experience also reported the richest diversity of teaching strategies to residents but rarely allowed residents to perform consent with their patients. Meanwhile, 2 other cluster provided a more balanced experience with some opportunities for practice with patients and some diversity of teaching- these clusters, respectively, consist of older, experienced general surgeons and surgeons in trauma and/or critical care. CONCLUSIONS: Surgeon's demographics, personal experiences, and specialty appear to significantly influence their teaching styles and the educational experience residents receive regarding informed consent.

RESUMO

BACKGROUND: Pediatric intestinal rehabilitation (PIR) programs are associated with improved outcomes in children with intestinal failure but remain heterogeneous nationally. This study characterizes PIR program components to aid those seeking to establish or expand a program. METHODS: Members of the Children's Hospital Association reporting a PIR program to the US News and World Report completed a 14-item questionnaire using the Qualtrics Online Survey Software. Programs were categorized as small or large (≤50 vs >50 patients) and new or established (≤10 vs >10 years). RESULTS: Seventy-one programs were identified and 61 surveys were returned for a response rate of 86%. Majority of programs had gastroenterology, surgery, nutrition, nursing, and social work services involved. Large programs (n = 34; 59%) were more likely to serve as referral centers; have greater participation by nursing, social work, and primary care; have more dedicated time by gastroenterology, surgery, nursing, nutrition, and social work; have more frequent meetings; and have various funding sources (P < .05). CONCLUSION: Critical components of a PIR program include gastroenterology, surgery, and nutrition services with strong nursing and social work support. These data document the components of modern PIR programs, though further studies on the relationship between program structure and patient outcomes are warranted.

RESUMO

BACKGROUND/PURPOSE: Though evidence-based clinical pathways for the diagnosis and treatment of pediatric appendicitis have been established, protocols guiding management of percutaneous abscess drains are lacking. We hypothesized a drain management protocol utilizing drain output and clinical factors instead of fluoroscopic drain studies would reduce interventional radiologic procedures without adversely impacting clinical outcomes. METHODS: A standardized protocol was uniformly adopted at a tertiary-care children's hospital in April 2016. A retrospective chart review included all cases of appendicitis requiring abscess drainage by interventional radiology three years pre- and postprotocol implementation. RESULTS: Fifty-eight patients (preprotocol = 39, postprotocol = 19) underwent percutaneous abscess drainage, of whom 52 (preprotocol = 34, postprotocol = 18) required a drain. Baseline demographics and clinical presentation were similar across groups. Following protocol implementation, total number of IR procedures decreased from 2.4 to 1.3 per patient (p = 0.004). There was no significant difference in the number of postprocedure diagnostic imaging studies, readmissions, or inpatient days, and there was a trend towards a decrease in number of drain days (10.7 to 5.7, p = 0.067). CONCLUSION: A standardized protocol for management of abscess drains for complicated appendicitis reduced the number of IR procedures without a negative impact on clinical outcomes or increase in alternative imaging studies. This approach may decrease radiation exposure, anesthetic administration, and resource utilization. TYPE OF STUDY: Treatment study (retrospective comparative study). LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND/PURPOSE: Surgeon overprescription of opioids is a modifiable contributor to the opioid epidemic. No clear guidelines exist for prescribing opioids to younger patients after surgery. We sought to determine postoperative opioid needs in pediatric/young adult patients after laparoscopic appendectomy. METHODS: Patients 5-20 years old who underwent laparoscopic appendectomy were included for study. All consented patients underwent chart review and were additionally called for an attempted interview. Caregivers were queried on analgesic use and adequacy of pain relief. The main outcome measures were: quantity of opioid used, desire for an opioid, presence of pain ≥4/10, and need for follow-up/call owing to pain. All opioids were converted into morphine milligram equivalents (MME). RESULTS: Seventy-three patients qualified for the study, 49 of whom completed a postoperative telephone interview. Of the interviewees, 83% did not use or desire an opioid and reported pain <4/10 after discharge. Five patients used an opioid upon discharge, and the average MME consumed was 23 (equivalent to 3 pills of 5 mg oxycodone). No zero-opioid patients had unanticipated follow-up for pain concerns. CONCLUSIONS: After hospital discharge following laparoscopic appendectomy, most patients have adequate analgesia without opioids. Opioid prescriptions should be offered sparingly and for no more than 25 MME. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Prognosis study.

RESUMO

OBJECTIVE: The optimal timing of a pull-through procedure for Hirschsprung Disease is unknown. We, therefore, compared outcomes of pull-throughs performed in the first 30 days of age to 31-120 days. STUDY DESIGN: Retrospective review of 282 patients in the NSQIP-Peds database from 2012-2016 of infants ≤120-days old and >36-weeks gestational age with Hirschsprung Disease who underwent primary pull-through. Primary outcome was postoperative and total length of stay (LOS). Operative morbidity and readmissions were also compared. RESULTS: Postoperative LOS in <31-day group was 8.3 days (SD- 8.3) vs. 4.3 days (SD- 5.5) in 31-120-day group (p < 0.001). This finding was maintained on multivariate linear regression. Complication and readmission rates did not differ between groups (readmission: 15.6 vs 13% p = 0.51; complication: 5.5 vs 10% p = 0.16). CONCLUSION: For appropriately selected patients with Hirschsprung Disease, delaying pull-through until the second month of life is associated with lower total and postoperative stays without increased readmissions or complications.

RESUMO

BACKGROUND: Abstracts presented at the American Academy of Pediatrics Section on Surgery (AAP) and American Pediatric Surgical Association (APSA) meetings can be taken as a reasonable representation of academic activity in pediatric surgery. We sought to assess ongoing trends in pediatric surgical research by analyzing the scientific content of each association's yearly meeting. METHODS: Abstracts presented at AAP and APSA between 2009 and 2013 were identified from the final printed programs (n = 910). Video abstracts (n = 34) were excluded. Collected data included title, authors, classification (basic science/clinical), presentation type (podium/poster), and topic. Publication as a journal article was determined using the abstract title/authors in a PubMed search. Journal impact factors were recorded for each journal and a composite impact factor (CIF) was calculated by dividing the sum of impact factors by the published articles per meeting. RESULTS: Number of abstracts presented, percentage published, abstract classifications, and presentation type remained consistent over the study period. The AAP meetings accepted a higher percentage of clinical abstracts: AAP 72.3 ± 3.4% versus APSA 65.9 ± 1.3%. The five most popular topics at both meetings were oncology, congenital diaphragmatic hernia, necrotizing enterocolitis, trauma, and appendicitis. The publication rate for clinical and basic science abstracts did not vary significantly over the study period, whereas CIFs were higher for basic science publications nearly every year. The percentage of podium abstracts published was significantly greater than poster abstracts, but no statistical difference in CIF was seen between podium- and poster-associated publications. CONCLUSIONS: Abstracts accepted and presented at the two major pediatric surgical specialty meetings more commonly involve clinical studies with a trend away from basic science. Despite this, basic science abstracts tended to be published in higher impact journals. This study attempts to quantify the quality of pediatric surgical research and serves as a baseline for future comparison.

RESUMO

BACKGROUND: Adolescents who use prescription opioids have an increased risk for future drug abuse and overdose, making them a high-risk population. Appendectomy is one of the most common surgical procedures in this age group, often requires opioid analgesia, and is performed by both pediatric and general surgeons. Prescription patterns comparing these two provider groups have not yet been evaluated; we hypothesize that general surgery providers prescribe more opioids for adolescent and young adult patients than do pediatric surgery providers. METHODS: A retrospective chart review was conducted across a single health system consisting of four hospitals. All uncomplicated laparoscopic appendectomies performed between January 1, 2016 and August 14, 2017 on patients aged 7-20 were included for analysis. Any case coded for multiple procedures, identified as converted to open, or had a length of stay >48 h were excluded. The primary outcome measure was amount of opioid prescribed postoperatively. To standardize different formulations and types of analgesia prescribed, prescriptions were converted into oral morphine equivalents (OMEs). For reference, one 5 mg pill of oxycodone equals 7.5 OME. Linear regression was performed controlling for patient weight, gender, race, insurance status, provider type (pediatric versus general surgery), and provider level (resident, advanced practice provider, and attending). RESULTS: A total of 336 pediatric laparoscopic appendectomies were analyzed, 148 by general surgeons and 188 by pediatric surgeons. Pediatric surgeons prescribed less opioid than general surgeons overall (59 OME versus 90 OME, P < 0.0001). For patients aged <13 y, there was no significant difference between pediatric (26 OME) and general (37 OME, P = 0.8921) surgeons. However, for the age group 13-20 y, pediatric surgeons prescribed 25% less opioid than general surgeons (90 OME versus 112.5 OME, P < 0.0001). Regression analysis demonstrated that being cared for by a general surgery service (+24.1 OME [95% confidence interval 9.8-38.3]) was associated with high prescribing, whereas having Medicaid was associated with lower prescription amounts (-16.4 OME [95% confidence interval -32.5 to -0.3]). CONCLUSIONS: After an uncomplicated laparoscopic appendectomy, general surgeons prescribe significantly more opioid to adolescent patients than do pediatric surgeons, even when controlling for age and weight. One substantial and modifiable contributor of the opioid epidemic is the amount of opioid prescribed. The variability of prescribing habits to adolescents and young adults demonstrates a clear need for increased education and guidelines on this topic, especially for surgeons who do not frequently treat the younger and more vulnerable population.

RESUMO

BACKGROUND: Postnatal evaluation of prenatally identified congenital lung malformations (CLMs) often includes a chest x-ray (CXR) and neonatal intensive care unit (NICU) admission for observation. With current efforts aimed at prioritizing value and resource utilization, we sought to assess the utility of this practice in infants with known CLMs. We hypothesized that CXR and NICU admission are overused and could be deferred in the majority of cases. METHODS: Clinical and radiographic data for infants with CLM from 2007 to 2016 were reviewed with IRB approval. Regression models were developed for respiratory support (RS), symptoms within 30 days of discharge (Sx30), and abnormal CXR. Predictors included initial symptoms (IS), birth weight (BW), gestational age (GA), cyst-volume-ratio (CVR) and abnormal CXR. Odds ratios (ORs) and ROC curves were generated for significant predictors (p < 0.05). RESULTS: Fifty-eight infants were identified. Eight were excluded because birth or surgery occurred outside of our institution. Another four were excluded for requiring immediate surgery, leaving forty-six for full analysis. All infants underwent initial CXR and NICU admission, and 22 (47.8%) had an abnormal CXR. Higher CVR (OR = 6.69, p = 0.024) and lower BW (OR = 0.27, p = 0.028) both increased the odds of an abnormal CXR. Applying optimal ROC cutoffs for CVR and BW would have safely eliminated 21 of 46 CXRs, increasing CXR sensitivity from 48% to 68%. For RS and Sx30, no variable, including abnormal CXR, significantly predicted outcomes. Twenty-seven infants (59%) had a NICU stay of <24 h and only three patients (6.8%) developed Sx30. CONCLUSIONS: Both CXR and NICU admission appear to be overused in infants with CLM. CXR result did not predict need for respiratory support or symptoms following discharge, and thus may not aid in the initial evaluation or in the prediction of future care needs. Using CVR and birth weight can guide CXR use and optimize its sensitivity. Need for NICU admission could not be predicted, but a majority of infants spent <24 h in the NICU without intervention, suggesting that NICU admission was likely not needed for all infants in this setting. LEVEL OF EVIDENCE: Study of diagnostic test, Level II evidence.

RESUMO

BACKGROUND: Health care spending in the US remains excessively high. Aside from complicated, large-scale efforts at health care cost reduction, there are still relatively simple ways in which individual hospitals can cut unnecessary costs from everyday operations. Inspired by recent publications, our group sought to decrease the costs associated with surgical instrument processing at a large, multihospital academic center. METHODS: This was a single-site observational study conducted at a large academic medical center. At the study start, all attending surgeons within the section of pediatric surgery agreed to standardize the pediatric surgery trays and to eliminate instruments that were deemed unnecessary from each tray. A multidisciplinary start-up meeting was held, and this meeting included stakeholders from central sterile processing, operating room nursing, scrub technicians, and materials management along with all five pediatric surgeons. Each tray was addressed individually. Instruments were eliminated from trays only if there was unanimous agreement among all the surgeons in the group. If no instruments in a given surgical tray were deemed necessary, the entire tray was eliminated from sterile processing rotation. Feedback questionnaires were drafted by the multidisciplinary team that participated in the start-up meeting. Surgeons were allowed to request for certain instruments to be placed back into the trays at any time, and the questionnaires also allowed for free-hand comments. Surgical kit preparation time was obtained from the institutional barcode scanning system. The cost per second of sterile processing labor was calculated using regional median salary for sterile processing technicians in the state of Connecticut. Using the pediatric surgery section as the model unit, this method was then applied to pediatric urology, neurosurgery, spine surgery, and orthopedics. RESULTS: The pediatric surgery section eliminated an average of 59.5% of instruments per tray, resulting in an overall reduction of 1826 (39.5%) instruments from rotation, 45,856 fewer instruments processed per year, and nine trays eliminated completely from regular rotation. Processing time for six commonly used trays was reduced by an average of 28.7%. The urology section eliminated 18 trays from regular rotation and 179 (10.1%) instruments in total. Pediatric orthopedics, neurosurgery, and spine sections eliminated 708 (17.1%), 560 (92.7%), and 31 (32.2%) instruments, respectively, resulting in approximately 18,804 fewer instruments processed per year. Among all five surgical sections, annual instrument cost avoidance after tray optimization was estimated at $53,193 to $531,929 using average instrument life spans ranging from 1-10 y. Negative feedback and requests for instrument replacement were both minimal on feedback questionnaires. CONCLUSIONS: Surgical tray optimization represents a relatively simple microsystem improvement that could result in significant hospital cost reduction. Although difficult to quantify, other gains from surgical kit optimization include decreased weight per tray, decreased materials cost, and decreased labor required to count, decontaminate, and pack surgical trays.

RESUMO

A 43-day-old boy presented with bacteremia after umbilical artery catheterization. Duplex ultrasound examination revealed a 1.1- × 1.6-cm mycotic infrarenal aortic aneurysm and an incidental asymptomatic occluded right common iliac artery. Resection and repair were completed by creating an everted, double-layered internal jugular vein patch. Screening ultrasound examination 10 months postoperatively demonstrated successful repair.

RESUMO

Neonatal surgery is recognized as an independent discipline in general surgery, requiring the expertise of pediatric surgeons to optimize outcomes in infants with surgical conditions. Survival following neonatal surgery has improved dramatically in the past 60 years. Improvements in pediatric surgical outcomes are in part attributable to improved understanding of neonatal physiology, specialized pediatric anesthesia, neonatal critical care including sophisticated cardiopulmonary support, utilization of parenteral nutrition and adjustments in fluid management, refinement of surgical technique, and advances in surgical technology including minimally invasive options. Nevertheless, short and long-term complications following neonatal surgery continue to have profound and sometimes lasting effects on individual patients, families, and society.

RESUMO

Here we report the creation of a novel tracheal construct in the form of an engineered, acellular tissue-stent biocomposite trachea (TSBT). Allogeneic or xenogeneic smooth muscle cells are cultured on polyglycolic acid polymer-metal stent scaffold leading to the formation of a tissue comprising cells, their deposited collagenous matrix, and the stent material. Thorough decellularization then produces a final acellular tubular construct. Engineered TSBTs were tested as end-to-end tracheal replacements in 11 rats and 3 nonhuman primates. Over a period of 8 weeks, no instances of airway perforation, infection, stent migration, or erosion were observed. Histological analyses reveal that the patent implants remodel adaptively with native host cells, including formation of connective tissue in the tracheal wall and formation of a confluent, columnar epithelium in the graft lumen, although some instances of airway stenosis were observed. Overall, TSBTs resisted collapse and compression that often limit the function of other decellularized tracheal replacements, and additionally do not require any cells from the intended recipient. Such engineered TSBTs represent a model for future efforts in tracheal regeneration.

RESUMO

Incidental appendectomy is the removal of the vermiform appendix accompanying another operation, without evidence of acute appendicitis. It is generally performed to eliminate the risk of future appendicitis. The risks and benefits of incidental appendectomy during various operations in children have been debated for over a century, but need to be revisited in light of innovations in medical practice, including minimally invasive surgery, improved imaging techniques, and use of the appendix as a tubular conduit for reconstruction. A detailed review was undertaken of the techniques, pathology, risks of appendectomy, utility of the appendix, and incidental appendectomy in the treatment of specific pediatric medical conditions. A comprehensive literature search was performed, and retrieved results were reviewed for relevance to the topic. The decision to perform a pediatric incidental appendectomy relies on informed consideration of the individual patient's co-morbid conditions, the indication for the initial operation, the future utility of the appendix, and the risk of future appendiceal pathology. The discussion includes a variety of situations and comorbid conditions that may influence a surgeon's decision to perform incidental appendectomy.

RESUMO

BACKGROUND: Intestinal circulation and mesenteric arterial (MA) reactivity may play a role in preparing the fetus for enteral nutrition. We hypothesized that MA vasoreactivity changes with gestation and vasodilator pathways predominate in the postnatal period. METHODS: Small distal MA rings (0.5-mm diameter) were isolated from fetal (116-d, 128-d, 134-d, and 141-d gestation, term ~ 147 d) and postnatal lambs. Vasoreactivity was evaluated using vasoconstrictors (norepinephrine (NE) after pretreatment with propranolol and endothelin-1(ET-1)) and vasodilators (NO donors A23187 and s-nitrosopenicillamine (SNAP)). Protein and mRNA assays for receptors and enzymes (endothelin receptor A, alpha-adrenergic receptor 1A (ADRA1A), endothelial NO synthase (eNOS), soluble guanylyl cyclase (sGC), and phosphodiesterase5 (PDE5)) were performed in mesenteric arteries. RESULTS: MA constriction to NE and ET-1 peaked at 134 d. Relaxation to A23187 and SNAP was maximal after birth. Basal eNOS activity was low at 134 d. ADRA1A mRNA and protein increased significantly at 134 d and decreased postnatally. sGC and PDE5 protein increased from 134 to 141 d. CONCLUSION: Mesenteric vasoconstriction predominates in late-preterm gestation (134 d; the postconceptional age with the highest incidence of necrotizing enterocolitis (NEC)) followed by a conversion to vasodilatory influences near the time of full-term birth. Perturbations in this ontogenic mechanism, including preterm birth, may be a risk factor for NEC.

RESUMO

PURPOSE: Historically, the rate of pathologic leadpoints in older children with intussusception is quoted as 20%-25%. Our anecdotal experience suggested a lower rate. We therefore compiled a case series to examine the actual incidence of pathologic leadpoint, and treatment success, by age. METHODS: A retrospective review was performed of all patients admitted with intussusception between 1998 and 2012 and tested for differences in anatomic location, presence of pathologic leadpoint, and need for operative intervention, on the basis of age. RESULTS: In total, 154 cases of intussusception were diagnosed in 141 patients (136 ileo-colic), 38 of which were in children older than 3 (29 ileo-colic). Considering all anatomic locations, older children were more likely to have a pathologic leadpoint (p-value 0.01); however subgroup analysis of ileo-colic intussusception demonstrated no difference (p-value 0.38). Additionally, there was no difference in the success of pneumatic or barium enema reduction on the basis of age (p-value 0.56). CONCLUSION: Despite historical reports of increased pathologic leadpoints in ileo-colic intussusception in older children, in this series the majority were idiopathic. Non-operative management was successful approximately 75% of the time, irrespective of age. In older age groups, there was an increased frequency of pathologic leadpoints in small bowel-small bowel intussusception.

RESUMO

OBJECTIVE: This study aimed to evaluate the feasibility and measure the impact of an in situ interdisciplinary pediatric trauma quality improvement simulation program. METHODS: Twenty-two monthly simulations were conducted in a tertiary care pediatric emergency department with the aim of improving the quality of pediatric trauma (February 2010 to November 2012). Each session included 20 minutes of simulated patient care, followed by 30 minutes of debriefing that focused on teamwork, communication, and the identification of gaps in care. A single rater scored the performance of the team in real time using a validated assessment instrument for 6 subcomponents of care (teamwork, airway, intubation, breathing, circulation, and disability). Participants completed a survey and written feedback forms. RESULTS: A trend analysis of the 22 simulations found statistically significant positive trends for overall performance, teamwork, and intubation subcomponents; the strength of the upward trend was the strongest for the teamwork (τ = 0.512), followed by overall performance (τ = 0.488) and intubation (τ = 0.433). Two hundred fifty-one of 398 participants completed the participant feedback form (response rate, 63%), reporting that debriefing was the most valuable aspect of the simulation. CONCLUSIONS: An in situ interdisciplinary pediatric trauma simulation quality improvement program resulted in improved validated trauma simulation assessment scores for overall performance, teamwork, and intubation. Participants reported high levels of satisfaction with the program, and debriefing was reported as the most valuable component of the program.

RESUMO

PURPOSE: Thymomas are rare pediatric malignancies with indolent behavior. There are fewer than 50 reported cases and no comprehensive review. We sought to evaluate our recent experience with pediatric thymomas, and comprehensively review the extant literature. METHODS: A systematic search of the PubMed database was performed using keywords: "thymoma", "pediatric", "juvenile", "childhood", and "child". Additional studies were identified by a manual search of the reference list. RESULTS: We report two patients with thymomas. We identified 22 case reports or series that described 48 patients; 62 % were male, 15 % presented with myasthenia gravis. Fifty percent were Masaoka Stage I, 15 % were Stage II, 13 % were Stage III, and 23 % were Stage IV. Four patients with early stage (I or II) disease were treated with adjuvant therapies in addition to surgical excision, while five patients with late stage (III or IV) disease treated with surgical excision alone. Of studies reporting at least 2-year follow-up, survival was 71 %. CONCLUSION: Pediatric thymomas are rare tumors with a slight male predominance. Wide variations were observed in the treatment of thymomas across all stages. Our review indicates a need for large database and multi-institutional studies to clearly elucidate clinical course, prognostic factors and outcome.

RESUMO

Congenital esophageal stenosis (CES) is associated with oesophageal atresia and tracheoesophageal fistula (EA-TEF). Tracheobronchial (cartilaginous) rests are typically found within the area of stenosis. The authors present a case report of EA-TEF associated with CES and present a modification of a novel technique to facilitate the management of CES. The impact of gastro-oesophageal reflux disease is discussed in this unique entity. Finally, the literature is reviewed for this unique entity.
