The Impact of the COVID-19 Pandemic on Geographic Placement of Applicants to General Surgery Residency Programs.

OBJECTIVE: COVID-19 greatly influenced medical education and the residency match. As new guidelines were established to promote safety, travel was restricted, visiting rotations discontinued, and residency interviews turned virtual. The purpose of this study is to assess the geographic trends in distribution of successfully matched General Surgery applicants prior to and after the implementation of pandemic guidelines, and what we can learn from them as we move forward. DESIGN: This was a retrospective review of 129 Accreditation Council for Graduate Medical Education (ACGME) accredited, academic General Surgery Residency Programs across 46 states and the District of Columbia. Categorically matched residents' medical schools (i.e., home institutions), medical school states, and medical school regions as defined per the Association of American Medical Colleges (AAMC), were compared to the same geographic datapoints as their residency program. Preliminary residents were excluded. Residents in the 2018, 2019, and 2020 cycles were sub-categorized into the "pre-COVID" group and residents in the 2021 and 2022 applications cycles were sub-categorized into the "post-COVID" group. The percentages of residents who matched at their home institution, in-state, and in-region were examined. SETTING: Multiple ACGME-accredited, university-affiliated General Surgery Residency Programs across the United States of America. PARTICIPANTS: A total of 4033 categorical General Surgery residents were included. RESULTS: Of 4033 categorical residents who matched between 2018 and 2022, 56.1% (n = 2,263) were in the pre-COVID group and 43.9% (n = 1770) were in the post-COVID group. In the pre-COVID group 14.4% (n = 325) of residents remained in-home (IH), 24.4% (n = 553) in-state (IS), and 37.0% (n = 837) in- region (IR), compared to 18.8% IH (n = 333), 27.8% IS (n = 492), and 39.9% IR (n = 706) in the post-COVID group, respectively. Significant increases for IH and IS resident matching at 4.5% and 3.4%, respectively, were noted in the post-COVID period (p < 0.05). CONCLUSION: The COVID-19 pandemic, and the ensuing changes adopted to promote safety, significantly impacted medical student opportunities and the General Surgery residency application process. General Surgery match data over the last 5 years reveals a statistically significant increase in the percentage of applicants matching at in-home and in-state institutions after the pandemic.

Implementation of an Online Intraoperative Assessment of Technical Performance for Surgical Trainees.

INTRODUCTION: Assessment of surgical resident technical performance is an integral component of any surgical training program. Timely assessment delivered in a structured format is a critical step to enhance technical skills, but residents often report that the quality and quantity of timely feedback received is lacking. Moreover, the absence of written feedback with specificity can allow residents to seemingly progress in their operative milestones as a junior resident, but struggle as they progress into their postgraduate year 3 and above. We therefore designed and implemented a web-based intraoperative assessment tool and corresponding summary "dashboard" to facilitate real-time assessment and documentation of technical performance. MATERIALS AND METHODS: A web form was designed leveraging a cloud computing platform and implementing a modified Ottawa Surgical Competency Operating Room Evaluation instrument; this included additional, procedure-specific criteria for select operations. A link to this was provided to residents via email and to all surgical faculty as a Quick Response code. Residents open and complete a portion of the form on a smartphone, then relinquish the device to an attending surgeon who then completes and submits the assessment. The data are then transferred to a secure web-based reporting interface; each resident (together with a faculty advisor) can then access and review all completed assessments. RESULTS: The Assessment form was activated in June 2021 and formally introduced to all residents in July 2021, with residents required to complete at least one assessment per month. Residents with less predictable access to operative procedures (night float or Intensive Care Unit) were exempted from the requirement on those months. To date a total of 559 assessments have been completed for operations performed by 56 trainees, supervised by 122 surgical faculty and senior trainees. The mean number of procedures assessed per resident was 10.0 and the mean number per assessor was 4.6. Resident initiation of Intraoperative Assessments has increased since the tool was introduced and scores for technical and nontechnical performance reliably differentiate residents by seniority. CONCLUSIONS: This novel system demonstrates that an online, resident-initiated technical assessment tool is feasible to implement and scale. This model's requirement that the attending enter performance ratings into the trainee's electronic device ensures that feedback is delivered directly to the trainee. Whether this aspect of our assessment ensures more direct and specific (and therefore potentially actionable) feedback is a focus for future study. Our use of commercial cloud computing services should permit cost-effective adoption of similar systems at other training programs.

Extended postoperative venous thromboembolism prophylaxis after bariatric surgery: a comparison of existing risk-stratification tools and 5-year MBSAQIP analysis.

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of 30-day mortality after metabolic and bariatric surgery (MBS). Multiple predictive tools exist for VTE risk assessment and extended VTE chemoprophylaxis determination. OBJECTIVE: To review existing risk-stratification tools and compare their predictive abilities. SETTING: MBSAQIP database. METHODS: Retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed (2015-2019) for primary minimally invasive MBS cases. VTE clinical factors and risk-assessment tools were evaluated: body mass index threshold of 50 kg/m2, Caprini risk-assessment model, and 3 bariatric-specific tools: the Cleveland Clinic VTE risk tool, the Michigan Bariatric Surgery Collaborative tool, and BariClot. MBS patients were deemed high risk based on criteria from each tool and further assessed for sensitivity, specificity, and positive predictive value. RESULTS: Overall, 709,304 patients were identified with a .37% VTE rate. Bariatric-specific tools included multiple predictors: procedure, age, race, gender, operative time, length of stay, heart failure, and dyspnea at rest; operative time was the only variable common to all. The body mass index cutoff and Caprini risk-assessment model had higher sensitivity but lower specificity when compared with the Michigan Bariatric Surgery Collaborative and BariClot tools. While the sensitivity of the tools varied widely and was overall low, the Cleveland Clinic tool had the highest sensitivity. The bariatric-specific tools would have recommended extended prophylaxis for 1.1%-15.6% of patients. CONCLUSIONS: Existing MBS VTE risk-assessment tools differ widely for inclusion variables, high-risk definition, and predictive performance. Further research and registry inclusion of all significant risk factors are needed to determine the optimal risk-stratified approach for predicting VTE events and determining the need for extended prophylaxis.

Utilizing Simulation to Evaluate Robotic Skill Acquisition and Learning Decay.

BACKGROUND: We aim to evaluate how new robotic skills are acquired and retained by having participants train and retest using exercises on the robotic platform. We hypothesized that participants with a 3-month break from the robotic platform will have less learning decay and increased retention compared with those with a 6-month break. METHODS: This was a prospective randomized trial in which participants voluntarily enrolled and completed an initial training phase to reach proficiency in 9 robot simulator exercises. They were then instructed to refrain from practicing until they retested either 3 or 6 months later. This study was completed at an academic medical center within the general surgery department. Participants were medical students, and junior-level residents with minimal experience in robotic surgery were enrolled. A total of 27 enrolled, and 13 participants completed the study due to attrition. RESULTS: Overall, intragroup analysis revealed that participants performed better in their retest phase compared with their initial training in terms of attempts to reach proficiency, time for completion, penalty score, and overall score. Specifically, during the first attempt in the retesting phase, the 3-month group did not deviate far from their final attempt in the training phase, whereas the 6-month group experienced significantly worse time to complete and overall score in interrupted suturing {[-4 (-18 to 20) seconds vs. 109 (55 to 118) seconds, P =0.02] [-1.3 (-8 to 1.9) vs. -18.9 (-19.5 to (-15.0)], P =0.04} and 3-arm relay {[3 (-4 to 23) seconds vs. 43 (30 to 50) seconds, P =0.02] [0.4 (-4.6 to 3.1) vs. -24.8 (-30.6 to (-20.3)], P =0.01] exercises. In addition, the 6-month group had a significant increase in penalty score in retesting compared with the 3-month group, which performed similarly to their training phase [3.3 (2.7 to 3.3) vs. 0 (-0.8 to 1.7), P =0.03]. CONCLUSIONS: This study identified statistically significant differences in learning decay, skills retention, and proficiency between 3-month and 6-month retesting intervals on a robotic simulation platform.

From the Operating Room to Online: Medical Student Surgery Education in the Time of COVID-19.

BACKGROUND: On March 17, 2020 the Association of American Medical Colleges recommended dismissal of medical students from clinical settings due to the COVID-19 pandemic. Third-year (M3) and fourth-year (M4) medical students were at home, M4s were interested in teaching, and residents and faculty had fewer clinical responsibilities due to elective surgery cancellations. To continue M3 access to education, we created a virtual surgery elective (VSE) that aimed to broaden students' exposure to, and elicit interest in, general surgery (GS). METHODS: Faculty, surgical residents, and M4s collaborated to create a 2-wk VSE focusing on self-directed learning and direct interactions with surgery faculty. Each day was dedicated to a specific pathology commonly encountered in GS. A variety of teaching methods were employed including self-directed readings and videos, M4 peer lectures, case-based learning and operative video review with surgery faculty, and weekly surgical conferences. A VSE skills lab was also conducted to teach basic suturing and knot-tying. All lectures and skills labs were via Zoom videoconference (Zoom Video Communications Inc). A post-course anonymous survey sent to all participants assessed changes in their understanding of GS and their interest in GS and surgery overall. RESULTS: Fourteen M3s participated in this elective over two consecutive iterations. The survey response rate was 79%. Ninety-one percent of students believed the course met its learning objectives "well" or "very well." Prior to the course, 27% reported a "good understanding" and 0% a "very good" understanding of GS. Post-course, 100% reported a "good" or "very good" understanding of GS, a statistically significant increase (P = 0.0003). Eighty-two percent reported increased interest in GS and 64% reported an increase in pursuing GS as a career. CONCLUSIONS: As proof of concept, this online course successfully demonstrated virtual medical student education can increase student understanding of GS topics, increase interest in GS, and increase interest in careers in surgery. To broaden student exposure to GS, we plan to integrate archived portions of this course into the regular third-year surgery clerkship and these can also be used to introduce GS in the preclinical years.

Development of a laparoscopic surgical skills simulation curriculum: Enhancing resident training through directed coaching and closed-loop feedback.

BACKGROUND: Performance feedback through peer coaching and rigorous self-assessment is a critical part of technical skills improvement. However, formal collaborative programs using operative video-based skills assessments to generate peer coaching feedback have only been validated among attending surgeons. In this study, we developed a unique longitudinal, simulation video-based laparoscopic skills resident curriculum using video-based peer coaching and evaluated its association with skills acquisition among surgical trainees. METHODS: The laparoscopic simulation curriculum consists of a pre-practice laparoscopic skill video recording, followed by receipt of directed coaching and feedback on performance from a faculty coach, a peer coach, and self-coaching. Residents then completed 6 weeks of feedback-directed practice and submitted a second post-practice laparoscopic skill video recording of the same skill, which was evaluated by a minimally invasive surgery expert grader. All general surgery residents in a single institution were enrolled, with 107 residents completing the curriculum in its initial 2 years. RESULTS: Overall, more than two-thirds of residents achieved skills proficiency on their expert assessments, with similar rates of residents achieving skills proficiency at all postgraduate year levels. Significant improvements between the pre-practice assessments and post-practice assessments were most frequently seen in the instrument handling, precision, and motion & flow categories (P < .05 each). Faculty provided the highest number and proportion of closed-loop comments; residents' self-coaching feedback had the lowest number of closed-loop comments, with 83% of self-assessments containing none. CONCLUSION: In this study, we describe the successful implementation of a longitudinal laparoscopic skills video-based coaching curriculum designed to improve residents' laparoscopic technical abilities through iterative directed practice supplemented by formative closed-loop feedback. This feasible, reproducible, and low-cost simulation curriculum can be adapted to other training programs and skills acquisition endeavors. This program also prepares trainees for ongoing performance feedback after completion of residency through rigorous self-assessment and peer-to-peer coaching.

Orientation in Perpetuity: An Online Clinical Decision Support System for Surgical Residents.

BACKGROUND: Limiting variability is an essential element to improving quality of care. Frequent resident turnover represents a significant barrier to clinical standardization. Trainees joining new surgical services must familiarize themselves with the guidelines and protocols that direct patient care as well as their learning objectives and expectations. A clinical decision support system (CDSS) is a dynamic, searchable electronic resource intended for use at the point of care. The CDSS can provide convenient and timely access to relevant information for residents, allowing them to incorporate the most up-to-date protocols and guidelines in their daily care of patients. The objective of this quality improvement intervention was to determine the objective rate of CDSS utilization and its subjective value to residents. MATERIALS AND METHODS: An internally developed, web-based CDSS including essential, clinically useful documents was created for use by trainees on a busy pediatric surgery service. A standardized orientation was provided to each resident and fellow on joining the service, complemented by a summary card to be attached to the trainee's ID badge. CDSS usage was monitored using web analytics. Trainees who rotated before and after the CDSS launch were surveyed regarding attitudes toward clinical resources and confidence in patient management. RESULTS: Documents published to the CDSS included 33 clinical guideline documents and 207 additional educational and support files including reference materials from service orientation were made available to trainees and staff. Goals for resident usage were established by evaluation and adaptation of early traffic patterns. Analysis of web traffic collected over 14 consecutive months revealed utilization above target levels, with 4.0 average weekly page views per trainee (IQR: 1.6-5.6). A total of 60 survey responses were received (54% of trainees invited); majorities of rotating trainees and survey respondents were trainees in general surgery and most were interns. Mean composite scores reflected a trend toward improved satisfaction when seeking CDSM (before intervention 3.18 [SD 0.73], after intervention 3.92 [SD 0.70], range 1-5) which was statistically significant (P = 0.005). Mean scores also improved across five of six components of the composite score (mean improvement 0.75, range: 0.53-0.92), four of which were statistically significant (P = 0.001-0.038). Most (59%) respondents reported that they used the CDSS frequently. CONCLUSIONS: Convenient access to a CDSS resulted in greater than expected utilization as well as higher resident satisfaction with and confidence in materials provided. A CDSS is a promising tool offering quick access to high-quality information in challenging trainee environments.

Prehospital Versus Trauma Center Glasgow Coma Scale in Pediatric Traumatic Brain Injury Patients.

BACKGROUND: Traumatic brain injury (TBI) is a major source of morbidity and mortality in children. The Glasgow Coma Scale (GCS) can be challenging to calculate in pediatric patients. Our objective was to determine its reproducibility between prehospital providers and pediatric trauma hospital personnel. MATERIALS AND METHODS: The institutional trauma database for a level 1 pediatric trauma center was queried for patients aged ≤18 y who presented with a TBI. Demographics, mechanism, prehospital GCS, and trauma center GCS were collected. Agreement was evaluated with weighted kappa (κ) coefficients (0 = agreement no better than that expected by chance alone, 1 = perfect agreement). RESULTS: The inclusion criteria were met by 1711 patients, 263 of whom were aged <3 y. Prehospital GCS and trauma center GCS differed in 766 patients (44.8%). Agreement between prehospital GCS and trauma center GCS was moderate for all patients (κ = 0.61, 95% confidence interval [CI] 0.57-0.64). Agreement was slightly better than chance alone in patients with trauma center GCS between 9 and 12 y (κ = 0.09, 95% CI 0.03-0.15) and was lower for children aged 0-2 y (κ = 0.51, 95% CI 0.42-0.61) than for those aged between 3 and 18 y (κ = 0.63, 95% CI 0.59-0.66). Younger children were more likely to have score differences of at least 3 points (21.3% versus 13.6% of 3- to 18-y-olds, P < 0.001). CONCLUSIONS: Prehospital and trauma center GCS scores frequently disagree in children, particularly in TBI patients aged <3 y and those with moderate TBI. Centers should consider the inconsistency of the pediatric GCS when triaging TBI patients.

Examining length of stay after commonly performed surgical procedures in ACS NSQIP pediatric.

BACKGROUND: The objective of this study was to identify ranges of postoperative length of stay (LOS) for common pediatric procedures using a large multi-institutional database. MATERIALS AND METHODS: A retrospective analysis of the most frequently performed general surgical procedures in the ACS-NSQIP Pediatric (2013-2015) was performed. These included laparoscopic appendectomy (LA), laparoscopic cholecystectomy, laparoscopic gastrostomy, laparoscopic esophagogastric fundoplication (LF), thoracoscopic repair of pectus excavatum (TPE), open appendectomy (OA), enterostomy closure (OEC), gastrostomy closure (OGC), and bowel resection (OBR). Patients aged <6 mo or >18 y, operations with major concurrent procedures, same-day discharges, operations performed >2 d after admission, and inpatient deaths were excluded. Postoperative LOS was examined for each procedure, including multivariable analysis of risk factors for postoperative LOS > 75th percentile. RESULTS: A total of 29,557 cases were identified and included procedure subgroups ranging from 505 (OBR) to 19,260 (LA) cases. Procedure-specific median postoperative LOS (75th percentile; 90th percentile) were LA 1 d (2 d; 5 d); laparoscopic cholecystectomy 1 d (1 d; 2 d); laparoscopic gastrostomy 2 d (2 d, 4 d); laparoscopic fundoplication 3 d (4 d, 6 d); thoracoscopic repair of pectus excavatum 4 d (5 d, 6 d); OA 3 d (6 d, 9 d); OEC 4 d (6 d, 10 d); OGC 1 d (1 d, 2 d); and OBR 6 d (10 d, 20 d). Preoperative risk factors for high postoperative LOS varied by procedure and included patient demographics, admission factors, case characteristics, and comorbidities. CONCLUSIONS: The range of postoperative LOS and risk factors for high postoperative LOS for commonly performed procedures varied considerably. These results may be a useful reference for benchmarking and resource utilization analyses at the institutional and health systems levels.

Laparoscopic versus open inguinal hernia repair in children ≤3: a randomized controlled trial.

PURPOSE: Laparoscopy is being increasingly applied to pediatric inguinal hernia repair. In younger children, however, open repair remains preferred due to concerns related to anesthesia and technical challenges. We sought to assess outcomes after laparoscopic and open inguinal hernia repair in children less than or equal to 3 years. METHODS: A prospective, single-blind, parallel group randomized controlled trial was conducted at three clinical sites. Children ≤3 years of age with reducible unilateral or bilateral inguinal hernias were randomized to laparoscopic herniorrhaphy (LH) or open herniorrhaphy (OH). The primary outcome was the number of acetaminophen doses. Secondary outcomes included operative time, complications, and parent/caregiver satisfaction scores. RESULTS: Forty-one patients were randomized to unilateral OH (n = 10), unilateral LH (n = 17), bilateral OH (n = 5) and bilateral LH (n = 9). Acetaminophen doses, LOS, complications, and parent/caregiver scores did not differ among groups. Laparoscopic unilateral hernia repair demonstrated shorter operative time, a consistent finding for overall laparoscopic repair in univariate (p = 0.003) and multivariate (p = 0.010) analysis. No cases of testicular atrophy were documented at 2 (SD = 2.7) years. CONCLUSION: Children ≤3 years of age in our cohort safely underwent LH with similar pain scores, complications, and recurrence as OH. Parents and caregivers report high satisfaction with both techniques.

Contemporary management of recurrent pectus excavatum.

BACKGROUND: Optimal management of recurrent pectus excavatum (PE) has not been established. Here, we review our institutional experience in managing recurrent PE to evaluate long-term outcomes and propose an anatomic classification of recurrences, and a decision-making algorithm. METHODS: Clinical records of patients undergoing repair of recurrent PE (1996-2011) were reviewed. Univariate and multivariate logistic regression analyses were employed to examine patient characteristics as potential predictors for re-recurrence. RESULTS: Eighty-five patients with recurrent PE were identified during the study period. The initial operation was a Ravitch procedure in 85% of cases. Revision procedures were most frequently Nuss repairs (N=73, 86%), with remaining cases managed via open approach. Overall cosmetic and functional results were satisfactory in 67 patients (91.8%) managed with Nuss and in 7 (58%) patients managed with other techniques. Seven (8%) patients required additional surgical revision. Multivariate analysis identified no statistically significant patient or procedural factors predictive of re-recurrence. CONCLUSION: This study demonstrates that the Nuss procedure can be an effective intervention for recurrent pectus excavatum, regardless of the initial repair technique. However, open repair remains valuable when managing severe cases with abnormalities of the sternocostal junction and cartilage regrowth under the sternum.

A randomized trial of laparoscopic versus open Nissen fundoplication in children under two years of age.

AIMS: The surgery of gastroesophageal reflux disease (GERD) is common in modern pediatric surgical practice. Any differences in perioperative and long-term clinical outcomes following laparoscopic (LN) or open Nissen (ON) fundoplication have not been comprehensively described in young children. This randomized, prospective study examines outcomes following LN versus ON in children<2 years of age. METHODS: Four surgeons at a single institution enrolled patients under 2 years of age that required surgical management of GERD, who were then randomized to LN or ON between 2005 and 2012. A universal surgical dressing was employed for blinding. Analgesia and enteral feeding pathways were standardized. The primary outcome was postoperative length of stay. Perioperative outcomes and long-term follow up were collected as secondary outcomes and used to compare groups. RESULTS: Of 39 enrolled patients, 21 were randomized to ON and 18 to LN. Length of postoperative hospital stay, time of advancement to full enteral feeds, and analgesic requirements were not significantly different between treatment cohorts. The LN group experienced longer median operating times (173 vs 91 min, P<0.001) and higher surgical charges ($4450 vs $2722, P=0.002). The incidence of post-discharge complications did not differ significantly between the groups at last follow-up (median 42 months). CONCLUSIONS: This randomized trial comparing postoperative outcomes following LN vs ON did not detect statistically significant differences in short- or long-term clinical outcomes between these approaches. LN was associated with longer surgical time and higher operating room costs. The benefits, risks, and costs of laparoscopy should be carefully considered in clinical pediatric surgical practice.

Extracorporeal fetal support: a new animal model with preservation of the placenta.

BACKGROUND: Previous models of support for premature sheep fetuses have consisted of cesarean delivery followed by catheterization of umbilical or central vessels and support with extracorporeal membrane oxygenation (ECMO). The limitations of these models have been insufficient blood flow, significant fetal edema, and hemorrhage related to anticoagulation. METHODS: We performed a gravid hysterectomy on 13 ewes between 135 and 145days gestational age. The uterine vessels were cannulated bilaterally and circulatory support was provided via ECMO. Successful transition was defined as maintenance of fetal heart rate for 30minutes after establishing full extracorporeal support. Circuit flow was titrated to maintain mixed venous oxygen saturation (SvO2) of 70-75%. RESULTS: Seven experiments were successfully transitioned to ECMO, with an average survival time of 2hours 9minutes. The longest recorded time from cannulation to death was 6hours 14minutes. By delivering a circuit flow of up to 2120ml/min, all but one of the transitioned uteri were maintained within the desired SvO2 range. CONCLUSION: We report a novel animal model of fetal ECMO support that preserves the placenta, mitigates the effects of heparin, and allows for increased circuit flow compared to prior techniques. This approach may provide insight into a technique for future studies of fetal physiology.

The "weekend effect" in pediatric surgery - increased mortality for children undergoing urgent surgery during the weekend.

BACKGROUND: For a number of pediatric and adult conditions, morbidity and mortality are increased when patients present to the hospital on a weekend compared to weekdays. The objective of this study was to compare pediatric surgical outcomes following weekend versus weekday procedures. METHODS: Using the Nationwide Inpatient Sample and the Kids' Inpatient Database, we identified 439,457 pediatric (<18 years old) admissions from 1988 to 2010 that required a selected index surgical procedure (abscess drainage, appendectomy, inguinal hernia repair, open fracture reduction with internal fixation, or placement/revision of ventricular shunt) on the same day of admission. Outcome metrics were compared using logistic regression models that adjusted for patient and hospital characteristics as well as procedure performed. RESULTS: Patient characteristics of those admitted on the weekend (n=112,064) and weekday (n=327,393) were similar, though patients admitted on the weekend were more likely to be coded as emergent (61% versus 53%). After multivariate adjustment and regression, patients undergoing a weekend procedure were more likely to die (OR 1.63, 95% CI 1.21-2.20), receive a blood transfusion despite similar rates of intraoperative hemorrhage (OR 1.15, 95% CI 1.01-1.26), and suffer from procedural complications (OR 1.40, 95% CI 1.14-1.74). CONCLUSION: Pediatric patients undergoing common urgent surgical procedures during a weekend admission have a higher adjusted risk of death, blood transfusion, and procedural complications. While the exact etiology of these findings is not clear, the timing of surgical procedures should be considered in the context of systems-based deficiencies that may be detrimental to pediatric surgical care.

Age at presentation of common pediatric surgical conditions: Reexamining dogma.

PURPOSE: The commonly cited ages at presentation of many pediatric conditions have been based largely on single center or outdated epidemiologic evidence. Thus, we sought to examine the ages at presentation of common pediatric surgical conditions using cases from large national databases. METHODS: A retrospective analysis was performed on Healthcare Cost and Utilization Project databases from 1988 to 2009. Pediatric discharges were selected using matched ICD9 diagnosis and procedure codes for malrotation, intussusception, hypertrophic pyloric stenosis (HPS), incarcerated inguinal hernia (IH), and Hirschsprung disease (HD). Descriptive statistics were computed. RESULTS: A total of 63,750 discharges were identified, comprising 2744 cases of malrotation, 5831 of intussusception, 36,499 of HPS, 8564 of IH, and 10,112 of HD. About 58.2% of malrotation cases presented before age 1. Moreover, 92.8% of HPS presented between 3 and 10weeks. For intussusception, 50.3% and 91.4% presented prior to ages 1 and 4years, respectively. Also, 55.8% of IHD cases presented before their first birthday. For HD, 6.5% of cases presented within the neonatal period and 45.9% prior to age 1year. CONCLUSION: Our findings support generally cited presenting ages for HPS and intussusception. However, the ages at presentation for HD, malrotation, and IH differ from commonly cited texts.

A pilot comparison of standardized online surgical curricula for use in low- and middle-income countries.

IMPORTANCE: Surgical conditions are an important component of global disease burden, due in part to critical shortages of adequately trained surgical providers in low- and middle-income countries. OBJECTIVES: To assess the use of Internet-based educational platforms as a feasible approach to augmenting the education and training of surgical providers in these settings. DESIGN, SETTING, AND PARTICIPANTS: Access to two online curricula was offered to 75 surgical faculty and trainees from 12 low- and middle-income countries for 60 days. The Surgical Council on Resident Education web portal was designed for general surgery trainees in the United States, and the School for Surgeons website was built by the Royal College of Surgeons in Ireland specifically for the College of Surgeons of East, Central and Southern Africa. Participants completed an anonymous online survey detailing their experiences with both platforms. Voluntary respondents were daily Internet users and endorsed frequent use of both print and online textbooks as references. MAIN OUTCOMES AND MEASURES: Likert scale survey questionnaire responses indicating overall and content-specific experiences with the Surgical Council on Resident Education and School for Surgeons curricula. RESULTS: Survey responses were received from 27 participants. Both online curricula were rated favorably, with no statistically significant differences in stated willingness to use and recommend either platform to colleagues. Despite regional variations in practice context, there were few perceived hurdles to future curriculum adoption. CONCLUSIONS AND RELEVANCE: Both the Surgical Council on Resident Education and School for Surgeons educational curricula were well received by respondents in low- and middle-income countries. Although one was designed for US surgical postgraduates and the other for sub-Saharan African surgical providers, there were no significant differences detected in participant responses between the two platforms. Online educational resources have promise as an effective means to enhance the education of surgical providers in low- and middle-income countries.

Operative management of acquired Jeune's syndrome.

BACKGROUND: Acquired Jeune's syndrome is a severe iatrogenic deformity of the thoracic wall following a premature and aggressive open pectus excavatum repair. We report herein our technique and experience with this rare condition. METHODS: From 1996 to 2011, nineteen patients with acquired Jeune's syndrome were retrospectively identified in a tertiary referral center. The technique used to expand and reconstruct the thoracic wall consisted of 1) release of the sternum from fibrous scar tissue, 2) multiple osteotomies along the lateral aspect of the ribs with anterior advancement of costal-cartilages to protect the heart, 3) stabilization of the thorax by placing a curved bar for retrosternal support and, 4) restoration of the sterno-costal junction by wiring the lower cartilages to the edge of the sternum. RESULTS: Major complications observed in this series were: bar displacement (seven cases), postoperative death from cardiac arrest following bronchoscopy (one case), late cardiac tamponade from migration of wire suture fragment (one case), and need for multiple reoperations (one case). Long-term cosmetic results and improvement in daily quality of life were reported as positive in the majority of cases. CONCLUSIONS: Anterior chest wall reconstruction successfully treated our series of patients with acquired Jeune's syndrome. This multifaceted technique is an effective procedure that allows expansion of the thoracic cavity and improvement of aerobic activity.

Use of risk stratification indices to predict mortality in critically ill children.

UNLABELLED: The complexity and high cost of neonatal and pediatric intensive care has generated increasing interest in developing measures to quantify the severity of patient illness. While these indices may help improve health care quality and benchmark mortality across hospitals, comprehensive understanding of the purpose and the factors that influenced the performance of risk stratification indices is important so that they can be compared fairly and used most appropriately. In this review, we examined 19 indices of risk stratification used to predict mortality in critically ill children and critically analyzed their design, limitations, and purposes. Some pediatric and neonatal models appear well-suited for institutional benchmarking purposes, with relatively brief data acquisition times, limited potential for treatment-related bias, and reliance on diagnostic variables that permit adjustment for case mix. Other models are more suitable for use in clinical trials, as they rely on physiologic variables collected over an extended period, to better capture the interaction between organ systems function and specific therapeutic interventions in acutely ill patients. Irrespective of their clinical or research applications, risk stratification indices must be periodically recalibrated to adjust for changes in clinical practice in order to remain valid outcome predictors in pediatric intensive care units. Longitudinal auditing, education, training, and guidelines development are also critical to ensure fidelity and reproducibility in data reporting. CONCLUSION: Risk stratification indices are valid tools to describe intensive care unit population and explain differences in mortality.

Risk factors for conversion from laparoscopic to open surgery: analysis of 2138 converted operations in the American College of Surgeons National Surgical Quality Improvement Program.

Minimal access procedures have influenced surgical practice and patient expectations. Risk of laparoscopic conversion to open surgery is frequently cited but vaguely quantified. The present study examines three common procedures to identify risk factors for laparoscopic conversion to open (LCO) events. Cross-sectional analysis using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP; 2005 to 2009) identified cases with laparoscopic procedure codes for appendectomy, cholecystectomy, and bariatric procedures. The primary outcome was conversion of a laparoscopic procedure to its open equivalent. Summary statistics for laparoscopic and LCO groups were compared and logistic regression analysis was used to estimate patient and operative risk factors for conversion. Of 176,014 selected laparoscopic operations, 2,138 (1.2%) were converted. Most patients were female (68%) and white (71.2%); mean age was 45.1 years. LCO cholecystectomy was significantly more likely (n = 1526 [1.9%]) and LCO bariatric procedures were less likely (n = 121 [0.3%]); appendectomy was intermediate (n = 491 [1.0%], P < 0.001). Patient factors associated with LCO included male sex (P < 0.001), age 30 years or older (P < 0.025), American Society of Anesthesiologists Class 2 to 4 (P < 0.001), obesity (P < 0.01), history of bleeding disorder (P = 0.036), or preoperative systemic inflammatory response syndrome or sepsis (P < 0.001). LCO was associated with greater incidence of postoperative complications, including death, organ space surgical site infection, sepsis, wound dehiscence, and return to the operating room (P < 0.001). Overall LCO incidence is low in hospitals participating in ACS-NSQIP. Conversion risk factors include patient age, sex, obesity, and preoperative comorbidity as well as the procedure performed. This information should be valuable to clinicians in discussing conversion risk with patients.
