    Abstract Background and objectives: Preoperative malnutrition is associated with increased postoperative morbidity. The perioperative nutrition score (PONS) was developed to identify patients at risk of malnutrition. We sought to assess the correlation between preoperative PONS and postoperative outcomes in pediatric inflammatory bowel disease (IBD) patients.
    Methods: We performed a retrospective cohort study of IBD patients, less than 21 years of age, who underwent elective bowel resection between June 2018 and November 2021. Patients were divided based upon whether they met PONS criteria. The primary outcome was postoperative surgical site infections.
    Results: 96 patients were included. Sixty-one patients (64%) met at least one PONS criteria, while 35 patients (36%) met none. PONS positive patients more frequently received preoperative TPN supplementation (p < .001). There was no difference in preoperative oral nutritional supplementation between groups. Patients that screened positive for PONS had a longer hospital stay (p = .002), more readmissions (p = .029), and more surgical site infections (p = .002).
    Conclusions: Our data highlight the prevalence of malnutrition in the pediatric IBD population. Patients who screened positive had worse postoperative outcomes. Further, very few of these patients received preoperative optimization with oral nutritional supplementation. There is a need for standardization of nutritional evaluation to improve preoperative nutritional status and postoperative outcomes.

    Abstract 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.

    Abstract Background: Complications from esophageal button battery impactions remain a real fear for practicing pediatric gastroenterologists and surgeons. This case describes a child who developed an aorto-esophageal fistula 25 days after initial battery ingestion and survived due to prompt placement of an aortic stent via minimally invasive surgery, avoiding an open procedure.
    Case presentation: A 6-year-old female presented acutely with a mid-esophageal button battery impaction witnessed by her parents. Presenting symptoms included chest pain and emesis. Button battery location and size were confirmed on X-ray. She underwent removal with flexible esophagogastroduodenoscopy (EGD) and rigid esophagoscopy. She was admitted to the hospital and received conservative medical management, with serial cross-sectional imaging via chest MRIs to assess the evolution of her injury according to available national guidelines, and was discharged after 12 days of close inpatient monitoring. Despite these measures the patient represented 25 days post-ingestion with hematemesis from a new aorto-esophageal fistula, requiring emergent cardiac catheterization with successful, life-saving aortic stent placement. She remained admitted for an additional 12 days of monitoring as her diet was advanced slowly post-catheterization. Since this second hospitalization she continues to do well, with outpatient follow-up by multiple subspecialists.
    Conclusions: This case highlights the continued uncertainty regarding the risk of developing this complication, as well as gaps in the current literature and guidelines for managing these patients following ingestion and esophageal injury. It also details the unique course following development of this complication and its surgical repair.

    Abstract Objective: This study aims to investigate the utility and success of daily conference synopses emails ("Daily Dispatches") sent to surgical attending physicians, fellows, and residents to foster resident and faculty development.
    Design: Emails were distributed by the surgical residency program director (PD), summarizing each day of a surgical conference. Two prospective electronic surveys were administered to surgical residents, fellows, and attending surgeons to evaluate the value of this Daily Dispatch method.
    Setting: Institutional; Medstar Georgetown University Hospital, Department of Surgery, Washington, DC.
    Participants: Email synopses were sent to surgical attendings, fellows and residents. Pilot survey was distributed to 60 participants, main survey sent to 74 participants.
    Results: The response rate for the pilot survey was 41.6% (25/60). When asked about the mode of delivery, 96% of respondents wanted to maintain the email medium when compared to a lecture, paper handout, or the use of social media. The response rate for the main survey was 31.1% (23/74). Almost all (91%) respondents reported reading the emails. Within this group, 70% "agreed" or "strongly agreed" that the emails were useful. Furthermore, 90% reported learning "at least one new thing" and 80% confirmed these "emails provide meaningful content they would not otherwise obtain".
    Conclusion: Individualized daily synopsis emails highlighting relevant content provided meaningful information from conferences to non-attendees. The emails were well received and useful. Daily Dispatches meet an important need in dissemination of information traditionally gathered only by the rate-limiting step of conference attendance.

    Abstract Objective: In the spring of 2010, a categorical general surgery postgraduate year (PGY)-2 position became available at our academic medical center secondary to attrition of a PGY-1 resident. We sought to study the unique characteristics of applicants to that position and to describe the selection process with hopes to stimulate additional studies about the unique challenges of recruiting applicants into advanced standing positions.
    Design: Applications were received via e-mail and reviewed to characterize the applicant pool. An Excel spreadsheet was used to organize data. Characteristics assessed included United States Medical Licensing Examination (USMLE) scores, Educational Commission for Foreign Medical Graduates status, Alpha Omega Alpha Honor Society status, sex, academic performance, number of case logs, volunteer and job experience, leadership roles, research experience including submissions, and advanced degrees. These characteristics were compared to those of the PGY-1 applicants through the Match that year.
    Setting: Academic medical center.
    Participants: Applicants for a categorical general surgery PGY-2 position in 2010.
    Results: A total of 129 applicants provided the requested documents. There were 104 males, 25 females, no Alpha Omega Alpha Honor Society candidates, and 82 international candidates. Of all, 46 candidates experienced academic difficulties. Quantitative averages include USMLE 1: 214.17, USMLE 2: 215.74, American Board of Surgery In Training Examination (ABSITE) percentile = 51.96, ABSITE 2 = 46.00, grand total case log: 192.10. Advanced degrees included 2 MBAs, 6 MPHs, and 7 nonphysiology MSs. The selection process to fill the position started on 3/25/2010 when the announcement was published and ended on 5/11/2010 when the offer of acceptance was sent. The selected applicant integrated well with the peers and just graduated from our residency as one of the leaders of the graduating class.
    Conclusions: Although the attrition rate in general surgery remains high, there is a dearth of literature about how best to replace residents. The hardship of replacing residents highlights the importance of studying this group to improve the recruitment process and the quality of replacement residents. The selection process was time consuming and presented its own challenges given the lack of a computerized system for screening. It lasted nearly 7 weeks requiring faculty time commitment to mine through application data/e-mails, correspond with applicants, conduct interviews, and ultimately select an applicant for the position. This is the first study to investigate the applicant pool to advanced standing positions in general surgery and we present it as a pilot study to stimulate further research efforts.

    Abstract Purpose: To assess the indications, safety and outcomes of tunneled central venous catheters (CVCs) placed via a cutdown approach into the axillary vein in children, an approach not well described in this population.
    Methods: A retrospective cohort study was performed on pediatric patients who received CVCs via open cannulation of the axillary vein or one of its tributaries between January 2006 and October 2016 at two hospitals.
    Results: A total of 24 axillary CVCs were placed in 20 patients [10 male (42%); mean weight 7.0 kg (SD 2.9); mean age 10 months (SD 6)]. The most common indications for axillary vein access included neck or chest wall challenges (tracheostomies or chest wall wounds) (n = 18). The median duration of line placement was 140 days (IQR 146). The most common indications for removal were completion of therapy (n = 7, 39%) and infection (n = 5, 28%). There were no early complications. Long-term complications included infection (n = 5) or catheter malfunction (n = 3).
    Conclusions: Tunneled CVC placement via a cutdown approach into the axillary vein or its tributary can be an effective alternative approach to obtain long-term vascular access in children. Outcomes may be comparable to lines placed in traditional internal jugular and subclavian vein locations.
