Early introduction to essential communication skills is important. We sought to determine if a handoff curriculum (HC) would improve confidence, decrease anxiety, and increase participation in clinical handoffs during the surgical clerkship.A multi-center prospective cohort study was performed at two medical schools. Training in the intervention group (HC) consisted of a didactic lecture, video review, and practice session. Students completed a pre-clerkship knowledge test and confidence/anxiety/handoff experience questionnaire pre- and post-clerkship.There were no significant differences in pre-clerkship handoff experiences between institutions except having previously witnessed a verbal handoff (School A 96.4% versus School B 76.2%, P = 0.01). While there were no significant differences in post-clerkship confidence or anxiety, HC students were significantly more involved with written sign-outs (52.9% versus 18.2%, P = 0.02) and verbal handoffs (29.4% versus 4.6%, P = 0.03).Medical students exposed to handoff training shared similar confidence and anxiety scores compared to those that were not, however, they were more involved in handoff experiences during their surgical clerkship. Early introduction to handoff skills may encourage greater participation during subsequent clinical experiences.

Background Testicular germ cell tumors are uncommon tumors that are encountered by pediatric surgeons and urologists and require a knowledge of appropriate contemporary evaluation and surgical and medical management. Method A review of the recommended diagnostic evaluation and current surgical and medical management of children and adolescents with testicular germ cell tumors based upon recently completed clinical trials was performed and summarized in this article. Results In this summary of childhood and adolescent testicular germ cell tumors, we review the initial clinical evaluation, surgical and medical management, risk stratification, results from recent prospective cooperative group studies, and clinical outcomes. A summary of recently completed clinical trials by pediatric oncology cooperative groups is provided, and best surgical practices are discussed. Conclusions Testicular germ cell tumors in children are rare tumors. International collaborations, data-sharing, and enrollment of patients at all stages and risk classifications into active clinical trials will enhance our knowledge of these rare tumors and most importantly improve outcomes of patients with testicular germ cell tumors. Level of evidence This is a review article of previously published and referenced level 1 and 2 studies, but also includes expert opinion level 5, represented by the American Pediatric Surgical Association Cancer Committee.

Background Oral candidiasis (OC) is an oral mucosal disorder due to Candida genus. Its predisposing factor among patients with HIV/AIDS is mainly decreasing CD4 count. OC is commonly caused by Candida albicans. As CD4 decreases, the shift to C. non-albicans has been observed. Objective To evaluate the association of Candida species with CD4 count and clinical features in HIV/AIDS patients with OC. Patients and methods This is a cross-sectional study. A total of 114 oral rinse solution samples from HIV/AIDS patients with OC were collected. Candida species identification was done by culture in Chromagar followed by VITEK 2. The association of Candida species with CD4 count and clinical features was analyzed using Pearson’s χ2 and Kruskal–Wallis tests. Results There was growth of 149 isolates in culture from 114 patients. C. albicans was found in 104 (69.7%) isolates. Candida non-albicans were found in 45 (30.3%) isolates, namely Candida krusei in 22 (14.85%), Candida glabrata in 12 (8.1%), Candida tropicalis in six (4.05%), Candida dubliniensis in two (1.3%), Candida parapsilosis in two (1.3%), and Candida lipolytica in one (0.7%) isolate. Candida species was significantly associated with clinical types, episode types, pain on swallowing, CD4 count, and antiretroviral (ARV) use among all patients. Conclusion Among HIV/AIDS patients with OC, growth of C. albicans only was more common in higher CD4 count, while mixed growth of C. albicans and C. non-albicans was more common in lower CD4 count. Clinical features associated with growth of C. albicans only were pseudomembranous type, recurrent OC, absence of pain on swallowing, and patients on ARV, whereas those associated with mixed growth of C. albicans and C. non-albicans were cheilitis type, first-episode OC, presence of pain on swallowing, and ARV-naive patients.

Background Children's hospitals within larger hospitals (CH/LH) have the specific clinical advantage of easily facilitated collaboration between adult and children's surgeons. These collaborations, which we have termed hybrid surgical offerings (HSOs) are often required for disease processes requiring interventions that fall outside the customary practice of children's surgeons. Formal models to describe or evaluate these practices are lacking. Methods HSOs within a CH/LH were identified. Principles of systems-engineering were used to develop a standardized model (Children's Hybrid Enhanced Surgical Services [CHESS]) to describe and evaluate HSOs. Face validity was established via unstructured interviews of CH leaders and HSO surgeons. Areas for improved system-wide standardization and programmatic development were identified. Results HSOs were identified in collaboration with adult bariatric, minimally invasive, advanced endoscopic, endocrine, thoracic, and orthopedic trauma surgical services. The CHESS framework encompassed: 1) quality improvement metrics, 2) credentialing and oversight, 3) transitions of care, 4) pediatric family-centered care, 5) maintenance of the cycle of expertise, 6) continuing medical education, 7) scholarship. While HSOs fulfilled the majority of aforementioned programmatic domains across all six HSO-providing services, areas for improvement included maintaining a cycle of expertise (33%), quality improvement metrics (50%), and pediatric family-centered care (66%). Additional noted advantages included faster translation of adult innovation to pediatric care and facilitation of emergency interdisciplinary care. Conclusion Formal evaluation of HSOs is necessary to standardize and improve the quality of children's surgical care. Development of a structured framework such as CHESS addresses gaps in quality oversight and provides a basis for performance improvement, patient safety, and programmatic development.

Despite increased utilization of robotic-assisted surgery in the pediatric population during the past decade, reports of comparative analysis between robotic surgery and laparoscopic surgery are lacking. Our aim was to evaluate outcomes between pediatric robotic-assisted cholecystectomy (RC) and laparoscopic cholecystectomy (LC).A single institution retrospective analysis of 299 patients undergoing either RC or LC, between January 2015 and December 2018 was performed. Demographic data as well as clinical characteristics and related outcomes were abstracted and compared using univariate analysis. Related hospital costs were estimated using a charge to cost methodology.The median age of the cohort was 15.5 years (IQR 14.0-17.0); 76% females and 70% white, with 74% (n = 220) undergoing LC and 26% (n = 79) undergoing RC. The majority of RC were performed using single-site technique and RC proportion increased with time (10% in 2015 vs. 41% in 2018, p0.001). The majority of RC were more commonly attributed to patients with nonacute indications for cholecystectomy compared to acute clinical indications (87% vs. 13%). Median operative time was 98 min vs. 79 min for RC and LC respectively (p0.001). Median postoperative LOS was similar between groups (22 h). There were no significant differences in postoperative complication, in-hospital opioid utilization and 30-day readmissions. Average total hospital costs for RC were $15,519 compared to $11,197 for LC.Pediatric robotic-assisted cholecystectomy is feasible with similar outcomes compared to laparoscopic cholecystectomy. However, it is associated with longer operative times and higher costs. The single-site RC technique may provide a potential cosmetic benefit.

IntroductionData examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children.MethodsThis retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications.ResultsOf 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n=214, 80.5%). The most common procedures were appendectomies (n=78, 29.3%) and fracture repairs (n=40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p=0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications.ConclusionsPostoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients.Level of evidenceIii, Respiratory complications.

Introduction Laparoscopic splenectomy (LS) is the standard of care for hematologic disorders requiring splenectomy. Less is known about the outcomes following robotic-assisted splenectomy (RS) for this indication. Our aim was to describe outcomes of RS to LS in pediatric patients with hematologic disorders in our institution. Methods A single institution retrospective review was performed of pediatric patients undergoing LS vs. RS from 2014 to 2019. Patient demographics, diagnosis, spleen size, hospital length of stay (LOS), operative time, post-operative opioid use, and hospital charges were evaluated. Standard univariate analyses were performed. Results Twenty-four patients were included in the study (14 LS, 10 RS). The mean spleen size at the time of surgery was larger in the RS group compared to LS (14.5 cm vs. 12.2 cm, p = 0.03). Operative time between the two cohorts was comparable (RS 140.5 vs LS 154.9 min). Median LOS for RS was shorter than LS (2.1 vs. 3.2 days, p = 0.02). Cumulative postoperative opioid analgesic requirements were not significantly different between the groups (17.4 mg vs. 30.5 mg). The median hospital charges, including the surgical procedure and hospital stay were higher in the RS group ($44,724 RS vs $30,255 LS, p = 0.01). Conclusion Robotic splenectomy is a safe and feasible option for pediatric patients with hematologic disorders, and was associated with decreased LOS but higher charges compared to laparoscopic splenectomy. Further studies are required to delineate the optimal use and potential benefits of robot-assisted surgical techniques in children. Level of Evidence II.

The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes.A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed.Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6).Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

A growing number of tertiary children’s hospitals are utilizing robotic surgical technology. We sought to characterize national trends in pediatric surgical robotic case utilization and related drivers. Pediatric urology and pediatric surgery (abdominal and thoracic) procedures, performed from January 2010 to December 2019 across 19 U.S. tertiary care children’s hospitals, were identified using the Pediatric Health Information System (PHIS). Trends in robot utilization were evaluated by surgical subspecialty, procedure type, and number of individual operating surgeons. Increases were noted in the overall numbers of pediatric surgery (1.3% per quarter, p = 0.005) and urology robotic procedures (2.0% per quarter, p

Pediatric surgery remains the most competitive general surgery subspecialty. The authors suspected significant inflation in academic metrics since the last published paper. This study aimed to identify factors associated with applicant success in the match.After IRB approval, all applications to a single accredited pediatric surgery fellowship program were reviewed for match years 2014-2018. Matched and unmatched applicants were compared in an unadjusted and adjusted analysis.This training program received 414 of 425 total applications (97%). Match results were available for 388 (94%). Matched applicants were more likely to train in programs with pediatric surgery fellowships (64% vs. 28%) and to have dedicated research time (55% vs. 21%; all p 0.01). Matched applicants had more total publications (median: 12 vs. 7, p 0.01) and higher ABSITE scores (median: 64th vs. 59th percentile, p 0.01). Training in multiple programs negatively impacted the chance to match (p 0.01). The median number of publications per applicant increased over the study time period from 7 to 11 (p 0.01).The likelihood of matching into a pediatric surgery fellowship was related to the type of residency attended, dedicated research time, ABSITE scores, and number of publications. Overall, the total number of publications reported by all applicants increased.Retrospective Comparative Study.Level III.

Controversy remains regarding the impact of anti-TNFα agents on postoperative outcomes in Crohn’s disease. Patients (≥ 18 years) with Crohn’s disease (ICD-9, 555.0–555.2, 555.9) undergoing ileocolectomy between 2005 and 2013 were identified using the Truven MarketScan® database and stratified by receipt of anti-TNFα therapy. Multivariable logistic regression was performed to evaluate anti-TNFα use on emergency department (ED) visits, postoperative complications, and readmissions at 30 days, adjusting for potential confounders. Relationships between timing of anti-TNFα administration and outcomes were examined. The sample contained 2364 patients with Crohn’s disease undergoing ileocolectomy, with 28.5% (n = 674) who received biologic therapy. Median duration between anti-TNFα therapy and surgery was 33 days. Postoperative ED visits and readmission rates did not significantly differ among those receiving biologics and those that did not. Overall 30-day complication rates were higher among those receiving biologic therapy, namely related to wound and infectious complications. In multivariable analysis, anti-TNFα inhibitors were associated with increased odds of postoperative complications at 30 days (aggregate complications [OR 1.6], infectious complications [OR 1.5]). There was no significant association between timing of anti-TNFα administration and occurrence of postoperative outcomes. Anti-TNFα therapy is independently associated with increased postoperative infectious complications following ileocolectomy in Crohn’s disease. However, in patients receiving anti-TNFα therapy within 90 days of operative intervention, further delaying surgery may not attenuate risk of postoperative complications.

The repair of rectoperineal fistulae can pose a significant challenge to the pediatric surgeon given the proximity of the fistula to the urethra in males and vagina in females. In these children, a simple cutback procedure may leave the neoanus in a position anterior to the center of the sphincter, which theoretically could impair future continence. We devised an adaptation of the cutback anoplasty which we call the posterior rectal advancement anoplasty (PRAA) to treat patients with a rectoperineal fistula that is both narrow in lumen and located within, but at the anterior-most limit of the sphincter complex.Patient selection, operative steps, and perioperative care of patients undergoing PRAA are detailed.10 children (6 males, 4 females) underwent PRAA. There were no vaginal wall or urethral injuries. At 6 months postoperatively, all patients were passing stool spontaneously. No patients required dilation of the anoplasty in the postoperative period and there were no anal strictures identified.A modification of the cutback anoplasty can be performed in patients with a perineal fistula and the distal fistula tract within the sphincter complex. We have demonstrated that this can be performed safely and obviates the need for an anterior rectal wall dissection, thus eliminating the risk of injury to urethra or vagina.IV.

This study assessed inter-hospital variability in operative-vs-nonoperative management of pediatric adhesive small bowel obstruction (ASBO).A multi-institutional retrospective study was performed examining patients 1-21 years-of-age presenting with ASBO from 2010 to 2019 utilizing the Pediatric Health Information System. Multivariable mixed-effects logistic regression was performed assessing inter-hospital variability in operative-vs-nonoperative management of ASBO.Among 6410 pediatric ASBO admissions identified at 46 hospitals, 3,239 (50.5%) underwent surgery during that admission. The hospital-specific rate of surgery ranged from 35.3% (95%CI: 28.5-42.6%) to 74.7% (66.3-81.6%) in the unadjusted model (p 0.001), and from 35.1% (26.3-45.1%) to 73.9% (66.7-79.9%) in the adjusted model (p 0.001). Factors associated with operative management for ASBO included admission to a surgical service (OR 2.8 [95%CI: 2.4-3.2], p 0.001), congenital intestinal and/or rotational anomaly (OR 2.5 [2.1-3.1], p 0.001), diagnostic workup including advanced abdominal imaging (OR 1.7 [1.5-1.9], p 0.001), non-emergent admission status (OR 1.5 [1.3-1.8], p 0.001), and increasing number of complex chronic comorbidities (OR 1.3 [1.2-1.4], p 0.001). Factors associated with nonoperative management for ASBO included increased hospital-specific annual ASBO volume (OR 0.98 [95%CI: 0.97-0.99], p = 0.002), older age (OR 0.97 [0.96-0.98], p 0.001), public insurance (OR 0.87 [0.78-0.96], p = 0.008), and presence of coinciding non-intestinal congenital anomalies, neurologic/neuromuscular disease, and/or medical technology dependence (OR 0.57 [95%CI: 0.47-0.68], p 0.001).Rates of surgical intervention for ASBO vary significantly across tertiary children's hospitals in the United States. The variability was independent of patient and hospital characteristics and is likely due to practice variation.III.

OBJECTIVES:We pursued the use of regional analgesia (RA) to minimize the use of postoperative opioids. Our aim was to increase the use of postoperative RA for eligible surgical procedures in the NICU from 0% to 80% by June 30, 2019.METHODS:A multidisciplinary team determined the eligibility criteria, developed an extensive process map, implemented comprehensive education, and a structured process for communication of postoperative pain management plans. Daily pain team rounds provided an opportunity for collaborative comanagement. An additional 30 minutes for catheter placement was added in operating room (OR) scheduling so that it would not affect the surgeon OR time.RESULTS:There were 21 eligible surgeries in the baseline period and 34 in the intervention period. In total, 30 of 34 infants in eligible surgeries (88%) received RA. The average total opioid exposure in intravenous morphine milligram equivalents decreased from 5.0 to 1.1 mg/kg in the intervention group. The average time to extubation was 45 hours in the baseline period and 19.9 hours in the intervention group. After interventions, 75% of infants were extubated in the OR, as compared with 10.5% in the baseline period. No difference was seen in postoperative pain scores or postoperative hypothermia between the baseline and intervention groups.CONCLUSIONS:We used quality improvement methodology to develop a structured RA program. We demonstrated a significant reduction in opioid requirements and need for mechanical ventilation postoperatively for those infants who received RA. Our findings support safe and effective use of RA, and provide a framework for implementation of a similar program.

OBJECTIVE Our objective was to investigate whether racial/ethnic-based or payer-based disparities existed in the transfer practices of pediatric trauma patients from adult trauma center (ATC) to pediatric trauma center (PTC) in Pennsylvania. METHODS Data on trauma patients aged 14 years or less initially evaluated at level I and II ATC were obtained from the Pennsylvania Trauma Outcome Study (2008-2012) (n = 3446). Generalized estimating equations regression analyses were used to evaluate predictors of subsequent transfer controlling for confounders and clustering. Recent literature has described racial and socioeconomic disparities in outcomes such as mortality after trauma; it is unknown whether these factors also influence the likelihood of subsequent interfacility transfer between ATC and PTC. RESULTS Patients identified as nonwhite comprised 36.1% of the study population. Those without insurance comprised 9.9% of the population. There were 2790 patients (77.4%) who were subsequently transferred. Nonwhite race (odds ratio [OR], 4.3), female sex (OR, 1.3), and lack of insurance (OR, 2.3) were associated with interfacility transfer. Additional factors were identified influencing likelihood of transfer (increased odds: younger age, intubated status, cranial, orthopedic, and solid organ injury; decreased odds: operative intervention at the initial trauma center) (P < 0.05 for all). CONCLUSIONS Although we assume that a desire for specialized care is the primary reason for transfer of injured children to PTCs, our analysis demonstrates that race, female sex, and lack of insurance are also associated with transfers from ATCs to PTCs for children younger than 15 years in Pennsylvania. Further research is needed to understand the basis of these health care disparities and their impact.

A growing number of tertiary children's hospitals are utilizing robotic surgical technology. We sought to characterize national trends in pediatric surgical robotic case utilization and related drivers.Pediatric urology and pediatric surgery (abdominal and thoracic) procedures, performed from January 2010 to December 2019 across 19 U.S. tertiary care children's hospitals, were identified using the Pediatric Health Information System (PHIS). Trends in robot utilization were evaluated by surgical subspecialty, procedure type, and number of individual operating surgeons.Increases were noted in the overall numbers of pediatric surgery (1.3% per quarter, p = 0.005) and urology robotic procedures (2.0% per quarter, p 0.001), as well as the numbers of pediatric surgeons (7.5% per year, p 0.001) and pediatric urologists (7.8% per year, p 0.001) operating robotically. Biliary system and spleen surgery were the most common robotic pediatric surgery procedures (45.5%) and had stable utilization over time (- 0.8% per quarter, 95% CI - 2.3-0.8). Robotic foregut surgery showed the most rapid growth in utilization (2.1% per quarter, 95% CI 0.7-3.6, p = 0.004) in pediatric surgery, while mediastinal/thoracic surgery demonstrated a decrease in utilization (- 4.6%, 95% CI - 7.9-1.2, p = 0.008). Renal pelvis/ureter surgery was the most common robotic urologic procedure (55.8%) and also demonstrated the fastest growth utilization (2.2% per quarter, 95% CI 1.5-2.9, p 0.001) in urology.Utilization of robotic-assisted surgery in pediatric surgery and pediatric urology has increased both in case volume and the number of operating surgeons, with foregut and renal pelvis/ureter surgery responsible for the areas of greatest growth.

Pediatric Crohn's disease (CD) is increasing in incidence globally. Trends in specific types of inpatient pediatric CD-related surgical procedures have not been widely reported.Patients ≤20 years of age with CD were identified in the Kids' Inpatient Database for 2003, 2006, 2009, and 2012. Bowel resection, stoma creation, and perianal or percutaneous drainage procedures were identified using ICD-9 procedure codes, and trends were identified. Logistic regression was used to identify factors associated with surgical intervention and trends.Rates of overall bowel resection (including ileocolic resection, other small bowel resection, or other colon resection) did not change significantly over time. However, the odds of having a laparoscopic colon resection increased by 41% annually (p0.001). Rates of subsequent ileostomy formation increased (odds ratio 1.09, p0.001). Older age, male sex, fewer comorbidities, and treatment in large urban teaching hospitals were also associated with higher odds of undergoing bowel resection.This study noted a stable rate of all types of bowel resections and increase in post resection ileostomy formation in US pediatric inpatients with CD from 2003-2012. Other rates of many CD-related procedures have remained stable. Further studies correlating the effects of biologic agents on surgical rates are warranted.Treatment Study LEVEL OF EVIDENCE: Level III.

The purpose of this analysis was to assess the burden of Clostridium difficile infection in the hospitalized pediatric surgical population and to characterize its influence on the costs of care.There were 313,664 patients age 1-18 years who underwent a general thoracic or abdominal procedure in the Kids' Inpatient Database during 2003, 2006, 2009, and 2012. Logistic regression was used to model factors associated with the development of C difficile infection. A propensity score-matching analysis was performed to evaluate the influence of C difficile infection on mortality, duration of stay, and costs in similar patient cohorts. Population weights were used to estimate the national excess burden of C difficile infection on these outcomes.The overall prevalence of C difficile infection in the sampled cohort was 0.30%, with an increasing trend of C difficile infection over time in non-children's hospitals (P .001). C difficile infection was associated with younger age, nonelective procedures, increasing comorbidities, and urban teaching hospital status (P .001). An estimated 1,438 children developed C difficile infection after operation. After propensity score matching, the mean excess duration of stay and costs attributable to C difficile infection were 5.8 days and $12,801 (P .001), accounting for 8,295 days spent in the hospital and $18.4 million (2012 USD) in spending annually.C difficile infection is a relatively uncommon but costly complication after pediatric operative procedures. Given the increasing trend of C difficile infection among hospitalized surgical patients, there is substantial opportunity for reduction of inpatient burden and associated costs in this potentially preventable nosocomial infection.

Objective The aim of the study was to identify and evaluate scholarship in multi-institutional interventional surgical education trials. Summary background data Most research on interventions in surgical education occurs at individual institutions. These studies typically involve a small number of learners in a unique environment, thereby limiting their generalizability. The status of multi-institutional studies in surgical education remains unknown. Methods We searched the Pubmed, ERIC, PsycINFO, SCOPUS, and CINAHL databases for all English language articles published from January 1, 2000 to December 31, 2015 using the keywords "medical education," "surgical education," "multi-institutional," "multi-center," and related terms. Articles published in an English language peer-reviewed journal that described an educational intervention conducted at more than one institution and involving surgeons were included. Results Of 3511 identified articles, 53 met criteria for full-text review and inclusion in this review. The median number of institutional sites was 4, with a range of 2 to 54. The 2 most common areas of focus were technical skills (43% of studies) and clinical knowledge (32% of studies). These were also the 2 most commonly measured outcomes (technical skills 32% of studies, clinical knowledge 21% of studies). Thirteen percentage of studies measured only learner attitudes and perceptions rather than learning outcomes. Conclusions Multi-institutional surgical education studies do not uniformly incorporate characteristics of high quality research, particularly related to study design, measurable outcomes, and assessment tools used. Coordinated support, including grant funding, that addresses the challenging nature of multi-institutional surgical education research may improve the quality of these studies.

This chapter describes the surgical procedure for serial transverse enteroplasty (STEP) as performed by the following approach: open. The text includes an introduction that outlines the indications, risks, alternatives, essential steps, needed equipment, and variations in technique for the procedure in question. This is followed by a template operative dictation, which provides the reader with an operative report, such as is found in a patient chart or electronic medical record. A description is provided of the following critical concepts for this procedure: preoperative assessment with upper gastrointestinal (GI) follow through, abdominal entry, complete lysis of adhesions, assessment of bowel length and dilation, serial transverse enteroplasty, reassessment of bowel length, and abdominal closure.

Inguinal hernias in children are a result of failure of the processus vaginalis to obliterate leading to herniation of abdominal contents through the internal ring and into the inguinal canal. Most children are asymptomatic at presentation; however, some will present with acute incarceration with risk of strangulation. Diagnosis is based on physical examination. Ultrasound may occasionally rarely be helpful. Treatment is surgical with ligation of the hernia sac at the level of the internal ring. This can be completed electively unless the hernia is unreducible there is concern for incarceration or stangulation, at which time emergent repair is required. Inguinal hernia repair may be completed through an open or laparoscopic approach, based on surgeon preference. Assessment and repair of an asymptomatic contralateral patent processus vaginalis remains controversial.

This chapter describes the surgical procedure for repair of duodenal atresia as performed by the following approaches: open and laparoscopic. The text includes an introduction that outlines the indications, risks, alternatives, essential steps, needed equipment, and variations in technique for the procedure in question. This is followed by a template operative dictation, which provides the reader with an operative report, such as is found in a patient chart or electronic medical record. A description is provided of the following critical concepts for this procedure: open/laparoscopic access, delineation of anatomy, kocherization of the duodenum, assessment of web, assessment for additional intestinal atresias, creation of duodenoduodenostomy, and abdominal closure.

Background Surgical costs are influenced by perioperative care, readmissions, and further therapies. We aimed to characterize costs in hepato-pancreato-biliary surgery in the United States. Methods The MarketScan database (2008–2010) was used to identify privately insured patients undergoing pancreatectomy (n = 2254) or hepatectomy (n = 1702). Costs associated with the index surgery, readmissions, and total short-term costs were assessed from a third party payer perspective using generalized linear regression models. Results Mean total costs of pancreatectomy and hepatectomy were $107,600 (95% confidence interval [CI], 101,200–114,000) and $81,300 (95% CI, 77,600–85,000), respectively, with corresponding surgical costs of 69.2% and 60.9%. Ninety-day readmission costs were $36,200 (95% CI, 32,000–40,400) and $34,100 (95% CI, 28,100–40,100), respectively. In multivariate analysis, readmissions were associated with an almost two-fold increase in total costs in both pancreatectomy (cost ratio = 1.98; P Conclusions Hepato-pancreato-biliary surgery is associated with significant economic burden in the privately insured population. Substantial costs are incurred beyond the index surgical admission, with readmissions representing a major source of potentially preventable health care spending. Sustained efforts in defining high-risk populations and decreasing the burden of postoperative complications through a combination of prevention and improved outpatient management offer promising strategies to reduce readmissions and control costs.

Background Posterior sagittal anorectoplasty (PSARP) is the most common surgical treatment for patients with anorectal malformations. Such patients are often subjected to prolonged nil per os (NPO), antibiotic use, and use of parenteral nutrition. Our aim was to review our institutional experience with patients undergoing PSARP using an accelerated standardized postoperative pathway. Methods Our hospital database was queried from 2004 to 2016 for patients diagnosed with imperforate anus who underwent a surgical procedure. Short term outcomes, hospital length of stay (LOS), and cost were evaluated. Results Sixty-three patients were identified during the study period. Of these patients, 34 (54.0%) had a fistula to the urogenital tract or had no demonstrable fistula and one cloaca and 29 (46.0%) had a fistula in the perineum. Approximately half of patients underwent primary PSARP, including 8 patients with fistulas located in the vestibule and vagina in girls and two with no apparent fistulas (12.7% of total cohort). Only two postoperative complications occurred: one superficial surgical site infection and one perineal wound dehiscence. Among the whole cohort, median LOS was 3 days. Median time to PO intake was 2 days, and median cost was $11,532. No complications occurred among the subset of 8 patients undergoing primary PSARP. Conclusion Patients undergoing PSARP experienced similar outcomes compared to historical series, suggesting that the accelerated pathway for early refeeding and reduced use of antibiotics may be beneficial in appropriately selected patients. Type of study Case series with no comparison group Level of evidence Level IV.

Pediatric Crohn's disease (CD) with anorectal involvement has not been well characterized. We sought to describe trends in the prevalence of pediatric CD with anorectal involvement and its influence on health-care utilization.Patients (21 y of age) with an International Classification of Diseases, Ninth Revision diagnosis of CD (555.X) were identified in the Kid's Inpatient Database (2003, 2006, 2009, 2012) and stratified by anorectal involvement based on the International Classification of Diseases, Ninth Revision diagnosis and procedural codes. Patient characteristics and resource utilization (length of stay [LOS] and costs) were compared between CD patients with and without anorectal involvement using univariate and multivariable analyses. Propensity score matching was used to estimate attributable LOS and costs.There were 26,029 patients with CD identified in the study interval. Of these, 1706 (6.6%) had anorectal involvement. Those with anorectal disease were younger (age 16 versus 17 y old), more likely to be male (59.4% versus 49.9%) and black or Hispanic (24.7% versus 18.2%), and were more commonly treated in urban teaching hospitals compared with rural or nonteaching hospitals (83.2% versus 70.9%) (P 0.001 for all). The proportion of patients with anorectal involvement increased over time (odds ratio 1.03, 95% confidence interval 1.02-1.05). After propensity score matching, attributable LOS and costs were 0.5 d and approximately $1600, respectively.There has been an increase in the proportion of pediatric CD hospitalizations with anorectal manifestations. This pattern of disease is associated with longer hospitalization and higher costs compared with CD alone. Further research is required to understand the underlying etiology of these observed trends.

Thoracoscopic surgery has been increasingly utilized in treating pediatric congenital lung malformations (CLM). Comparative studies evaluating 30-day outcomes between thoracoscopic and open resection of CLM are lacking.There were 258 patients identified in pediatric NSQIP with a CLM and pulmonary resection in 2012-2013. Comparisons of patient characteristics and outcomes between surgical approaches were made using standard univariate statistics. In addition, a propensity score match was performed to evaluate outcomes in similar patient cohorts.One-hundred twelve patients (43.4%) received thoracoscopic resections and 146 patients (56.6%) received open resections. Patients undergoing open resections were more likely to be less than 5 months of age and have a comorbidity/preoperative condition (47.3% vs. 25.0%, p0.001). The extent of resection was a lobectomy in 84.8% of thoracoscopic and 92.5% of open resection patients. Median operative time was similar between both groups (thoracoscopic 172 vs. open 153.5 minutes). On univariate analysis, thoracoscopic resection was associated with decreased postoperative complications (9.8% vs. 25.3%, p=0.001) and LOS (3 vs. 4 days, p0.001). However, after adjusting for similar patient and operative characteristics, no significant differences were encountered between techniques.Thoracoscopic and open resection provide comparable 30-day outcomes and safety in the management of congenital lung malformations.

Aim Smoking is known to have a deleterious effect onCrohn’s disease (CD). The present study addressed thespecific impact of smoking on the outcome of surgeryfor CD.Method A review of the National Surgical QualityImprovement Program (NSQIP) database (2005–2012)identified 7631 patients with CD who underwent surgi-cal resection. Patients were stratified based on smokingstatus and were compared with univariate statisticaltests. Generalized linear regression and multiple logisticregressions were used to model the impact of smokingon the surgical outcome [length of stay (LOS), mortal-ity, postoperative complications and readmission]. Toconfirm the validity of the regression models and toevaluate the influence of smoking in comparable patientcohorts, a propensity score match was also performed.Results There were 2047 (26.8%) patients with CDidentified as current smokers, and 5584 (74.2%) identi-fied as non- or ex-smokers. Smokers were more likely tohave a pulmonary comorbidity, preoperative weight lossand a higher American Society of Anesthesiologists clas-sification. No differences in mortality were observedbetween smokers and non- or ex-smokers in univariateanalysis. In multivariate analysis, smoking status was notsignificantly associated with LOS. Morbidity (OR 1.20,P = 0.003), particularly infectious (OR 1.30,P < 0.001) and pulmonary (OR 1.87, P < 0.001) com-plications, and readmission (OR 1.58, P = 0.004) weresignificantly associated with smoking status. These find-ings were validated on propensity-score matching analy-sis.Conclusion In patients with CD, the detrimental effectsof smoking on surgical outcomes are driven by infec-tious and pulmonary complications, and by an increasedlikelihood of readmission.Keywords Inflammatory bowel disease, tobacco,NSQIP, readmissions, complications, propensity-scoreWhat does this paper add to the literature?Tobacco use is associated with deleterious effects on theactivity and severity of Crohn’s disease. This study pro-vides a more focused estimate of the attributable impactof smoking on adverse postoperative results, demon-strating that they are driven by infectious and pulmo-nary complications.

Introduction A diverting stoma is often performed at the time of low anterior resection (LAR) for rectal cancer after neoadjuvant chemoradiation (nCRT) to protect the anastomosis. The aim of this study was to compare surgical outcomes in large cohorts of mid-high rectal cancer patients undergoing LAR after nCRT with and without a diverting stoma. Methods Patients undergoing LAR for rectal cancer (ICD-9 diagnosis code 154.1) after nCRT were identified from the American College of Surgeons National Surgical Quality Improvement Program database records from 2005 to 2012. Using Current Procedural Terminology (CPT) codes for LAR for mid-high rectal tumors, patients were stratified into diverting stoma (CPT: 44146, 44208) or no diverting stoma (CPT: 44145, 44207) cohorts. Emergency resection, stage IV disease, and permanent end colostomy patients were excluded. Results We included 1,406 patients in the analysis. All patients received nCRT; 607 (43%) received a diverting stoma and 799 (57%) were not diverted. The diverted group was more likely to have a higher body mass index (28.3 vs 27.4 kg/m2; P = .02) and hypertension (46% vs 39%; P = .002). Otherwise, the group demographics and comorbidities were comparable. Overall morbidity was 28% for the entire cohort with no differences in deep organ space infection, sepsis and septic shock, unplanned reoperation, duration of stay, or overall mortality between the groups. Conclusion Diverting stoma does not decrease mortality or infectious complications in mid-high rectal cancer patients undergoing LAR after nCRT. The decision to construct a protective stoma should not be driven solely on the receipt of nCRT.

As the utilization of MRI in the assessment for paediatric appendicitis increases in clinical practice, it is important to recognize alternative diagnoses as the cause of abdominal pain. The purpose of this review is to share our institution's experience using MRI in the evaluation of 510 paediatric patients presenting with suspected appendicitis over a 30 month interval (July 2011 to December 2013). An alternative diagnosis was documented in 98/510 (19.2%) patients; adnexal pathology (6.3%, n = 32), enteritis–colitis (6.3%, n = 32), and mesenteric adenitis (2.2%, n = 11) comprised the majority of cases. These common entities and other less frequent illustrative cases obtained during our overall institutional experience with MRI for suspected appendicitis are reviewed.

Background The benefit of Ladd's procedure for malrotation at a Children's Hospital (CH) has not previously been established. Our aim was to characterize the potential variations in management and outcomes between CH and Non-Children's Hospitals (NCH) in the treatment of malrotation with Ladd's procedure. Methods There were 2827 children identified with malrotation and complete information from the Kids' Inpatient Database (2003, 2006, 2009). Outcomes were compared between CH and NCH and evaluated with logistic and linear regressions. Additional propensity score matching was used to balance covariates between CH and NCH. Results There were 2261 (80.0%) children with malrotation undergoing Ladd's procedures treated at CH; 566 (20.0%) were treated at NCH. In multivariate analysis, CH was associated with a 39% lower odds of resection ( p =0.004), with no differences observed for mortality, morbidity and LOS. Comparison of a propensity score matched cohort confirmed these findings, as well as demonstrated no significant differences in associated costs. Conclusions The majority of pediatric intestinal malrotation is managed at CH. While measured outcomes of mortality, morbidity, LOS, and costs were not different at NCH, CH was less likely to perform intestinal resection during Ladd's procedure.

Aim Compared with standard laparoscopic (SDL) approaches, less is known about the incidence of hernias after single-site laparoscopic (SSL) colorectal surgery. This study hypothesized that SSL colorectal surgery was associated with an increased risk of hernia development. Method Institutional retrospective chart review (September 2008–June 2013) identified 276 evaluable patients who underwent laparoscopic colorectal procedures. The following data were collected: demographic data, risk factors for the development of a hernia, operative details and postoperative course including the development of a hernia. Patients were stratified by laparoscopic technique to compare the characteristics of those undergoing SDL and SSL. Patients were subsequently stratified by the presence or absence of a hernia to identify associated factors. Results One hundred and nineteen patients (43.1%) underwent SDL and 157 patients (56.9%) underwent SSL surgery. The development of an incisional hernia was observed in 7.6% (9/119) of SDL patients compared with 17.0% (18/106) of SSL patients (P = 0.03) over a median 18-month follow-up. Similar proportions of patients developed parastomal hernias in both groups [SDL 16.7% (10/60) vs SSL 15.9% (13/80)]. Hernias were diagnosed at a median of 8.1 (SDL) and 6.5 (SSL) months following the index operation and were less likely to be incarcerated in the SSL group [SDL 38.9% (7/18) vs SSL 6.5% (2/31), P = 0.01]. Conclusion SSL colorectal surgery is associated with an increase in the incidence of incisional hernias but not parastomal hernias. Site of specimen extraction in SSL may contribute to the development of an incisional hernia.

Readmission after colectomy has become an important metric for measuring quality of care. Our aim was to investigate the impact of patient and hospital characteristics on 30-d readmission rates among patients undergoing colectomies in Pennsylvania.Data were obtained from the Pennsylvania Health Care Cost Containment Council, which included all patients undergoing colectomy during 2011 (n = 10,155). Characteristics of non-readmitted and readmitted patients were compared with univariate tests. The primary outcome was 30-d readmission, which was modeled using multivariable logistic regression.Of the 10,155 patients who underwent colectomy, 1492 (14.7%) were readmitted within 30 d of discharge. Readmission was influenced by the underlying diagnosis (P0.001). Additionally, readmission was more likely with a Charlson comorbidity index ≥ 2 (odds ratio [OR] = 1.57, P0.001), emergent admission (OR = 1.26, P = 0.001), an in-hospital complication (OR = 1.46, P0.001), lowest quartile for surgeon volume (OR = 1.24, P = 0.01), and construction of an ileostomy (OR = 2.31, P0.001). Factors associated with decreased likelihood of readmission included laparoscopic surgery (OR = 0.73, P0.001). No association with hospital volume was found.A 30-d readmission after colectomy is influenced by numerous patient- and surgeon-related factors. Reducing in-hospital complications, and improving patient education after ileostomy construction, provide substantial targets for intervention. Our data also suggest that there may be a critical range of colectomies performed annually by surgeons, greater than which no additional benefit is conferred in reducing readmissions, but below which there is an increased risk of readmission. Further research is needed to determine the influence of laparoscopic surgery in reducing readmission in equally matched patient populations.

Small intestinal injury is seldom described in the context of child abuse. Signs and symptoms are subtle, often leading to delays in diagnosis. We describe a 3-year-old boy initially admitted with severe blunt abdominal trauma from physical child abuse. He was successfully managed nonoperatively. The child was then hospitalized several times for nonspecific abdominal symptoms until diagnostic laparoscopy discovered a jejunal stricture with a proximal jejuno-jejunal fistula. Symptoms fully resolved after resection. Delayed presentation of small intestinal injury should remain on the differential diagnosis in the evaluation of persistent abdominal symptoms in a child with a prior history of physical abuse, even if imaging studies do not reveal specific abnormalities.

Background Readmission is increasingly being utilized as an important clinical outcome and measure of hospital quality. Our aim was to delineate rates, risk factors, and reasons for unplanned readmission in pediatric surgery. Materials and methods Retrospective review of pediatric patients (n=130,274) undergoing surgery (2013–2014) at hospitals enrolled in the Pediatric National Surgical Quality Improvement Program (NSQIP-P) was performed. Logistic regression was used to model factors associated with unplanned 30-day readmission. Reasons for readmission were reviewed to determine the most common causes of readmission. Results There were 6059 (n=4.7%) readmitted children within 30days of the index operation. Of these, 5041 (n=3.9%) were unplanned, with readmission rates ranging from 1.3% in plastic surgery to 5.2% in general pediatric surgery, and 10.8% in neurosurgery. Unplanned readmissions were associated with emergent status, comorbidities, and the occurrence of pre- or postdischarge postoperative complications. Overall, the most common causes for readmission were surgical site infections (23.9%), ileus/obstruction/gastrointestinal (16.8%), respiratory (8.6%), graft/implant/device-related (8.1%), neurologic (7.0%), or pain (5.8%). Median time from discharge to readmission was 8days (IQR: 3–14days). Reasons for readmission, time until readmission, and need for reoperative procedure (overall 28%, n=1414) varied between surgical specialties. Conclusion The reasons for readmission in children undergoing surgery are complex, varied, and influenced by patient characteristics and postoperative complications. These data inform risk-stratification for readmission in pediatric surgical populations, and help to identify potential areas for targeted interventions to improve quality. They also highlight the importance of accounting for case-mix in the interpretation of hospital readmission rates. Level of evidence 3.

Background Mistreatment of trainees remains a frequently reported phenomenon in medical education. One barrier to creating an educational culture of respect and professionalism may be a lack of alignment in the perceptions of mistreatment among different learners. Through the use of clinical vignettes, our aim was to assess the perceptions of trainees toward themes of potential mistreatment at different stages of training. Methods Based on observations from external experts embedded in the clinical learning environment, six thematic areas of potential mistreatment were identified: verbal abuse, specialty-choice discrimination, non-educational tasks, withholding/denying learning opportunities, neglect and gender/racial insensitivity. Corresponding clinical vignettes were created and distributed to 1) medical students, 2) incoming interns, 3) residents/fellows. Perceptions of the appropriateness of the interactions depicted in the vignettes were measured on a 5-point Likert scale. Scores were categorized into neutral or appropriate (≤3) or inappropriate (i.e. mistreatment) (>3) and compared using chi-squared tests. Results Four hundred twenty seven trainees participated (182 students, 120 interns, 125 residents/fellows). Proportions of students perceiving mistreatment differed significantly from those of interns and residents/fellows in domains of verbal abuse, specialty discrimination and gender/racial insensitivity (p

article i nfo Background/Purpose: Single-incision laparoscopic appendectomy has been associated with improved cosmetic benefits, and decreased postoperative pain. Less is known about costs and other outcomes. Our aim was to evaluate the costs and outcomes between transumbilical laparoscopic-assisted appendectomy (TULAA) and multiport laparoscopic appendectomy (MLA). Methods: IRB-approved retrospective review (September 2010-July 2013) of institutional medical records identified 372 pediatric patients undergoing laparoscopic appendectomy. Outcomes included costs, LOS and readmission. Costs were fully loaded operating costs from the hospital's cost accounting database. Generalized linear regression was used to assess costs of MLA and TULAA. A subgroup analysis was performed using only patients with non-perforated appendicitis. Results: There were 132 patients (35.5%) that underwent TULAA while 240 patients (65.5%) underwent MLA. Compared to MLA, TULAA was associated with decreased operative time (0.6 vs. 1.0 h, p b 0.0001), used in comparable proportions of interval appendectomies, but was performed less often for perforated appendicitis (9.8% vs. 22.9%, p = 0.002). Readmission and postoperative complications were similar between both groups. In the setting of non-perforated appendicitis, TULAA was associated with lower costs of $1378 relative to MLA (p = 0.009). Conclusions: In non-perforated appendicitis, TULAA is associated with lower costs and comparable rates of readmission and postoperative complications.

BACKGROUND: The American Association of Endocrine Surgeons initiated a fellowship match in 2007. The profile of applicants who successfully match into an endocrine surgery (ES) fellowship has not previously been characterized. METHODS: An institutional review board-approved, web-based survey was distributed to recent and current ES fellows. RESULTS: The survey response rate was 62% (56/90). The overall mean age was 33 years (standard deviation 63), 54% were female, and 37% self-identified as non-white. Only 5% entered their surgical training with the aim of specializing in ES. During residency, respondents were exposed to high volumes of index ES cases. Sixty-two percent had dedicated research time. At the time of fellowship application, the median number of publications was 5 (range, 0 to 25), and 30% of respondents had additional advanced degrees. CONCLUSION: Entering ES fellows has diverse backgrounds, with strong academic credentials. These data help inform the career mentoring of aspiring ES applicants.
