The Novel Use of Rare Earth Magnets for the Extraction of Metallic Soft Tissue Foreign Bodies in Children.

INTRODUCTION: Metallic foreign bodies (mFB) are common following penetrating injuries in children. The mFB commonly occur in the head and neck region and extremity soft tissues. Removal may be indicated due to morbidity related to pain or migration. Extraction can be challenging to localize, often requiring wide exposure, and may be difficult to achieve in cosmetically sensitive areas. Different technological adjuncts have been used to facilitate foreign body removal including fluoroscopy, ultrasound, and more recently in adults, surgical magnets. The most powerful commercially available magnets are rare earth magnets comprised of neodymium iron and boron (Ndy). With the goal of reducing radiation exposure and the morbidity of mFB removal with associated soft tissue injury in children, a strategy was introduced utilizing Ndy to optimize extraction with minimal soft tissue surgical dissection. MATERIALS AND METHODS: Two children with extremity mFB treated with Ndy between January 2021 and July 2021 were analyzed. We utilized commercially available ring type neodymium-iron-boron magnets with dimensions of 1 3/8-inch outer diameter x 1/8-inch inner diameter and 1/16 inch thick with a power of 13 200 gauss that were processed for use according to our hospital protocols. Our main clinical indication was for the detection and retrieval of small ferromagnetic foreign bodies embedded in superficial extremity soft tissues. RESULTS: In the operating room under general anesthesia, the mFB were localized utilizing fluoroscopy. A 1.0 cm skin incision was made into the subdermal soft tissues overlying the area of the mFB. No surgical tissue dissection was performed. The mFB could not be visualized in the soft tissue. Using fluoroscopy to localize the mFB, the Ndy was then placed into the wound in close proximity to the mFB. The mFB were immediately magnetized to the Ndy and the mFB were extracted from the soft tissues without any further surgical dissection. Two simple interrupted nylon sutures were placed to close the incision. The total operative time was 2 and 2.5 minutes respectively. The children recovered uneventfully and are without complication. CONCLUSIONS: The use of Ndy to remove extremity soft tissue mFB in children appears to be feasible, safe, and efficient. Use of the Ndy allowed extraction via a small incision, optimizing the aesthetic result and avoiding the need for cross-sectional imaging, extensive surgical dissection, tissue reconstruction and prolonged operative time or x-ray exposure. The development of magnets of increasing energy density may be indicated to further optimize metallic soft tissue foreign body extraction in children in a minimally invasive manner.

An Analysis of Preliminary General Surgery Residents' Matriculation into Categorical Positions.

OBJECTIVE: To analyze the effects of a pipeline program for preliminary general surgery (GS) residents to optimize their future enrollment into categorical positions. DESIGN: Retrospective review of non-designated preliminary (NDP) GS residents between 2014 and 2020 was conducted. Preliminary conversion rates (CRs) were analyzed for residents who matriculated to categorical GS residency or non-GS residency positions. SETTING: Howard University Hospital, Department of Surgery; tertiary academic hospital. PARTICIPANTS: PGY-1 (n = 14) and PGY-2 (n = 26) NDP GS residents RESULTS: Forty NDP GS residents studied (14 PGY-1 and 26 PGY-2). CR for the total cohort was 67.5% (n = 27), with 59.3% (n = 16) acquiring categorical GS positions and 40.7% (n = 13) obtaining categorical positions in other specialties. CR for PGY-1 residents into categorical GS position was 50% (n = 7), while PGY-2 residents had a CR of 34.6% (n = 9). No significant difference was observed between residents successfully matriculating into GS residency as a preliminary PGY-1 or PGY-2 (p = 0.34). Twelve preliminary residents secured categorical GS positions at this institution with 58.3% (n = 7) obtaining a PGY-1 position, 16.7% (n = 2) obtaining a PGY-2, and 25.0% (n = 3) obtaining a PGY-3 position. 7.1% (n = 1) of preliminary PGY-1 and 46.2% (n = 12) of preliminary PGY-2 residents went unmatched as of 2021. CONCLUSIONS: 67.5% of preliminary residents enrolled in categorical positions. Success rates were highest during the PGY-1 year. A residency program committed to uniform clinical curriculum, and standardized, metric-based decisions may have increased CR for preliminary GS residents. Public sharing of preliminary CRs to applicants may influence residency selection decisions, both for applicants and programs.

The Role of Devices in the Management of Pediatric Obesity.

PURPOSE OF REVIEW: Approximately 20% of children and adolescents in the USA suffer from obesity with significant long-term effects well into adulthood. Metabolic and bariatric surgery, although well adopted in the adult population, has been underutilized in children. RECENT FINDINGS: There are four categories of weight loss devices regulated by the Food and Drug Administration for use in adults - gastric bands, gastric balloon systems, electrical stimulation systems, and gastric emptying systems. In this commentary we discuss the role these devices may play in increasing the adoption of procedural intervention for severe obesity in children and adolescents.

Elective laparoscopic gastrostomy in children: potential for an enhanced recovery protocol.

PURPOSE: Gastrostomy tube placement is one of the most commonly performed pediatric surgical procedures and discharge is possible as early as the first postoperative day with early initiation of feeds postoperatively. We examined a national database to determine hospital length of stay (LOS) after elective laparoscopic gastrostomy in children. METHODS: We queried the 2012-2013 National Surgical Quality Improvement Program Pediatric (NSQIP-P) database, including all patients who underwent elective laparoscopic gastrostomy tube placement for failure to thrive or feeding difficulties. Demographic data, admission status, disposition at discharge, surgical subspecialty data and hospital LOS were extracted. RESULTS: A total of 599 patients underwent gastrostomy tube placement for failure to thrive or feeding intolerance. The majority, 52%, was male and 69.3% were White. The median age was 2.2 years (IQR 0.9-6.3). Of the total, 28.7% were infants. The median total hospital LOS was 2 days (IQR 1-2), with only 39% discharged in a day or less. CONCLUSION: Pediatric patients undergoing elective laparoscopic gastrostomy have a median hospital length of stay of 2 days, despite evidence that early feeding and discharge within 24 h is both feasible and safe. There is potential for the implementation of an enhanced recovery protocol as a quality metric for this procedure.

Current practice patterns for postoperative activity restrictions in children.

BACKGROUND: Postoperative activity restrictions are designed to prevent undue stress on a recent repair and minimize the risk of surgical complication, however, there is little evidence to support certain restrictions in clinical practice. For the pediatric population, there is a paucity of formal evaluations of postoperative activity restrictions, and little is known about current practice patterns among pediatric surgeons. This study aimed to describe national practice patterns of pediatric surgeons for postoperative activity recommendations following three common general surgical procedures. METHODS: A 7-item survey was sent to all American Pediatric Surgical Association (APSA) members regarding surgeon practice of recommended activity restrictions for school attendance, participation in playground or gym, participation in contact sports, and heavy lifting in children following 3 procedures: exploratory laparotomy, laparoscopic appendectomy, and inguinal hernia repair. Information on type and duration of clinical practice was also collected for each surgeon. Descriptive and bivariate analyses were performed. RESULTS: The survey was completed by 293 pediatric surgeons for a response rate of 28.9%. There was wide national variability in the recommended activity restrictions for children <12 years old among pediatric surgeons. Following laparoscopic appendectomy, 30.7%, 51.9% and 47.8% of surgeons recommends restriction of gym, contact sports, and heavy lifting for 2-3 weeks respectively, but 26.7%, 19.8%, and 22.2% do not recommend any restriction whatsoever of these three activities. Following inguinal hernia repair, 31.7%, 49.1% and 44.4% of surgeons recommend restriction of gym, contact sports, and heavy lifting for 2-3 weeks, but 30.8%, 30.8%, and 29.2% do not recommend any restriction of these three activities. Only 22% of surgeons change their activity restriction recommendations for children ≥12 years old, this decision was not associated with surgeon years in practice or type of practice. CONCLUSIONS: There is considerable variability in surgeon recommendations for activity restrictions following three general surgery procedures in children. While activity restrictions are rooted in the physiology of wound healing, there is little evidence to support the benefit of these restrictions in clinical practice. In addition, activity restriction may have unintended deleterious effects on a child's psychosocial well-being and quality of life. Further investigation should be pursued to understand the utility of activity restrictions in children and their impact on clinical outcomes and patient quality of life. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level V, expert opinion.

Current Practice in the Management of Spontaneous Pneumothorax in Children.

INTRODUCTION: There is a lack of pediatric-specific guidelines for the workup and management of primary spontaneous pneumothorax (PSP) in children. The aim of this study was to describe current practices among North American pediatric surgeons. MATERIALS AND METHODS: An online survey comprising 18 questions was sent out through the American Pediatric Surgical Association Outcomes and Clinical Trials Committee to all members. Bivariate analysis was performed using Chi-square analysis. RESULTS: A total of 287 surveys were completed (33% response rate). For a first episode of PSP, 57% of surgeons opt for chest tube drainage, 4% for upfront video-assisted thoracoscopic surgery (VATS), 3% for needle aspiration, and 29% for only oxygen administration. Eighty-one percent of surgeons report that the size of the pneumothorax influences management. However, neither practice setting (P = .87) nor years in practice (P = .11) correlated with initial management strategy. For patients with a persistent air leak after chest tube placement, there is wide variation in duration of observation before performing VATS, with 40% operating after 3 days, but 21% waiting at least 5 days. The use of chest computed tomography (CT) is also highly variable. Eighty-two percent of respondents perform surgery only after the second episode of PSP. Most perform a stapled apical blebectomy and mechanical pleurodesis for both initial and recurrent PSP. CONCLUSION: There is significant variation among pediatric surgeons in the management of spontaneous pneumothorax, including the use of CT, timing of operation, and duration of observation for air leak before performing surgery. Prospective data are needed to better inform guidelines and standardize practice.

Antibiotic Prophylaxis for Pyloromyotomy in Children: An Opportunity for Better Stewardship.

INTRODUCTION: Surgical site infection is very uncommon after pyloromyotomy in children, and it is considered a "clean" procedure under the traditional wound classification system. This study aims to investigate prophylactic antibiotic administration for pyloromyotomy among children's hospitals in the USA. METHODS: The Pediatric Health Information System (PHIS) database was retrospectively reviewed from 2014 to 2015 including all patients less than 1 year old who had a principal diagnosis of pyloric stenosis and underwent pyloromyotomy. Patient demographics, hospital length of stay, and perioperative antibiotic administration were extracted. RESULTS: A total of 4206 patients met study criteria. Most patients were male (84%) and Caucasian (70%). The median age at admission was 32 days (IQR 24-44 days), and median length of stay was 2 days (IQR 1-2 days). Antibiotics were administered perioperatively in 2153 (51%) patients with marked variation among children's hospitals. Antibiotics were given to more than 10% of patients in more than 90% of hospitals, and only two of 49 hospitals gave no antibiotic prophylaxis. CONCLUSIONS: This study has shown that at several tertiary-level children's hospitals in the USA, antibiotic prophylaxis is administered for pyloromyotomy, a "clean" procedure. This highlights the need for standardization of care and more effective antibiotic stewardship in pediatric surgery.

Optimal Timing of Postoperative Imaging for Complicated Appendicitis.

PURPOSE: Approximately one quarter of children with complicated appendicitis develop postoperative abscess, leading to additional procedures and increased length of stay (LOS), but the optimal timing of postoperative imaging to detect abscess is unknown. METHODS: The Pediatric Health Information System database was reviewed, and children who underwent laparoscopic appendectomy in 2013-2014 with postoperative LOS ≥5 days were included. Demographics, imaging, drainage procedures, LOS, and 30-day readmission were analyzed. Chi-squared analysis was performed. RESULTS: A total of 21,985 patients underwent laparoscopic appendectomy and 3332 met inclusion criteria. A total of 1174 (35.2%) patients underwent postoperative imaging, among whom 38.4% underwent ultrasound and 75.0% underwent computed tomography scan. Timing of first imaging varied significantly between hospitals, ranging from 0% to 76% on postoperative day (POD) 5. Initial imaging was performed on POD 5, 6, and 7 in 19.7%, 31.3%, and 36.2%, respectively. Imaging on POD 5 compared with POD 7 was associated with shorter LOS (10.6 ± 5.7 versus 11.8 ± 4.4 days), but also lower rates of intervention (42.4% versus 50.8%), increased repeat imaging (10.8% versus 5.2%), and higher readmission rates (35.9% versus 28.2%) (P < .05). CONCLUSION: Timing of postoperative imaging for complicated appendicitis is variable across hospitals. While earlier imaging was associated with a decreased LOS, these children also had lower rates of subsequent intervention coupled with higher rates of repeat imaging and readmission. These findings suggest that delaying imaging until at least POD 6 may maximize the diagnostic yield of imaging while decreasing radiation exposure and readmission. Prospective investigation should be undertaken to guide the development of standardized clinical practice guidelines for the management of perforated appendicitis.

Optimal timing of video-assisted thoracoscopic surgery for primary spontaneous pneumothorax in children.

PURPOSE: There is no consensus in the pediatric surgical community about when to recommend video-assisted thoracoscopic surgery (VATS) for patients with primary spontaneous pneumothorax (PSP). We aimed to identify factors that predict the likelihood of requiring VATS, and to compare recurrence rates and healthcare utilization among different management approaches to PSP. METHODS: A retrospective chart review and a telephone survey were conducted on all patients 12-21years who were diagnosed with PSP from 2007 to 2015. Data were extracted on patient demographics, initial management, hospital length of stay (LOS), and subsequent admissions, procedures, and recurrences. RESULTS: A total of 46 patients were included with a mean age of 16.1years (+/- 1.2). Most patients were male (41, 89%) and white (16, 44%). Initial management comprised chest tube drainage alone in 28 (61%), no intervention in 8 (17%), and VATS in 10 (22%). Total LOS was 6days (IQR 4-7) and was longer in patients who underwent VATS (p<0.001). Recurrence occurred in 17 patients (37%). However, recurrence and healthcare utilization were not significantly associated with initial management approach. Among those who had initial chest tube drainage, 14 (50%) underwent VATS on that admission, and 8 (28%) had subsequent surgery. Significant predictors of ultimately requiring VATS were presence of an air leak and partial lung expansion. CONCLUSION: Most patients with PSP currently undergo chest tube placement as initial management, although most eventually require VATS. Presence of an air leak and partial lung expansion on chest radiograph within the first 48h of management should prompt earlier surgical intervention. TYPE OF STUDY: Retrospective. LEVEL OF EVIDENCE: III.

Using accelerometers to characterize recovery after surgery in children.

BACKGROUND: Assessment of recovery after surgery in children remains highly subjective. However, advances in wearable technology present an opportunity for clinicians to have an objective assessment of postoperative recovery. The aims of this pilot study are to: (1) evaluate acceptability of accelerometer use in pediatric surgical patients, (2) use accelerometer data to characterize the recovery trajectory of physical activity, and (3) determine if postoperative adverse events are associated with a decrease in physical activity. STUDY DESIGN: Children aged 3-18-years-old undergoing elective inpatient and outpatient surgical procedures were invited to participate. Physical activity was measured using an Actigraph GT3X wristworn accelerometer for ≥2days preoperatively and 5-14days postoperatively. Time spent performing light (LPA) and moderate-to-vigorous physical activity (MVPA) was expressed in minutes/day. Physical activity for each postoperative day was calculated as a percentage of preoperative activity, and recovery trajectories were produced. Adverse events were reported and mapped against recovery trajectories. RESULTS: Of 60 patients enrolled, 25 (10 inpatients, 15 outpatients) completed the study procedures and were included in the analysis. For outpatient procedures, LPA recovered to preoperative level on postoperative day (POD) 7 and MVPA peaked at 90% on POD 8. For inpatient procedures, LPA peaked at 70% on POD 11, and MVPA peaked at 53% on POD 10. Adverse events in 2 patients were associated with a decline in activity. CONCLUSIONS: This study demonstrates that objective monitoring of postoperative physical activity using accelerometers is feasible in the pediatric surgical population. Recovery trajectories for inpatient and outpatient procedures differ. Accelerometer technology presents clinicians with a new potential tool for assessing and managing surgical recovery, and for determining if children are not recovering as expected. TYPE OF STUDY: Diagnostic Study. LEVEL OF EVIDENCE: III.

Spontaneous Pneumothorax in Children: National Management Strategies and Outcomes.

INTRODUCTION: The timing of surgical intervention in the management of spontaneous pneumothorax remains controversial. The aim of this multicenter review was to compare management strategies and outcomes in children with spontaneous pneumothorax. METHODS: We retrospectively reviewed patients 10-19 years old in the Pediatric Health Information System admitted for spontaneous pneumothorax from 2010 to 2014. Three treatment groups were identified based on initial hospital management-no intervention, initial chest tube placement, and operation; and outcomes were compared. RESULTS: A total of 1040 patients were included. The majority were male (82.1%) and White (71.1%). The mean age at first encounter was 15.7 ± 1.7 years. Initial treatment included no intervention in 336 (32.3%), chest tube in 497 (47.8%), and video-assisted thoracoscopic surgery (VATS) in 207 (19.9%). Ultimately, 417 (40.1%) patients underwent VATS during the initial admission and 559 (53.8%) during the initial admission or a subsequent encounter. Aggregate length of stay (LOS) was highest for those treated initially with chest tube alone (P < .001). For patients managed initially with chest tube, the probability of requiring surgery increased with each day of hospitalization. Initial operation was associated with a decreased risk of readmission (OR 0.67, 95% CI 0.50-0.90). Estimated adjusted hospital costs, aggregated across all encounters, were highest for chest tube alone (P < .001). CONCLUSION: Early VATS is associated with decreased hospital LOS, charges, and readmissions. For those managed initially with chest tube alone, the likelihood of requiring operation increases with each day hospitalized, and early conversion to operative management should be considered in patients with persistent pneumothorax or air leak.

Age at orchiopexy for undescended testis in the United States.

PURPOSE: Undescended testis (UDT) is the most common congenital anomaly of the male genitalia. The American Urological Association guidelines recommend orchiopexy by age 18months to ameliorate the risk of subfertility. The study aim was to assess adherence to these guidelines on a national level. METHODS: We retrospectively reviewed both the State Ambulatory Surgery Database (SASD) in 2012 and the Pediatric Health Information System (PHIS) for 2015. All patients aged 18years or less with a diagnosis of UDT who underwent orchiopexy were included. Demographic data including age at repair as well as surgical subspecialty and payer status were extracted. RESULTS: Analysis of the 2012 SASD for New Jersey, Florida, and Maryland yielded 1654 patients. The majority were white, 791 (48.3%), with a median age at repair of 4years (IQR 1-8). Most patients, 1048 (64%), had orchiopexy later than age 2. A total of 844 males were identified from the PHIS database. Of these, 63% were white. The median age at repair was 5years (IQR 1-9). There were 577 (68%) patients older than 2years at orchiopexy. CONCLUSION: Almost 70% of boys with undescended testes in the United States are undergoing orchiopexy at least 6months later than the recommended age. TYPE OF STUDY: Retrospective. LEVEL OF EVIDENCE: III.

Variation in prophylactic antibiotic use for laparoscopic cholecystectomy: need for better stewardship in pediatric surgery.

PURPOSE: The role of prophylactic antibiotics for elective laparoscopic cholecystectomy has been questioned over the last decade. Although gradually being discontinued in the adult population, the practice among pediatric surgeons remains unknown. Our aim was to investigate the use of perioperative antibiotics in children undergoing elective laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis and biliary dyskinesia. METHODS: We retrospectively reviewed the Pediatric Health Information System (PHIS) database for 2015 and selected all patients 18years old or younger who underwent LC for cholelithiasis (without cholecystitis) or biliary dyskinesia. Demographic and hospital data were extracted as well as antibiotics administered and surgical complications. RESULTS: A total of 1112 patients from 44 hospitals were identified with a median age of 15years (IQR 13-16years). Eight out of every 10 hospitals routinely give prophylactic antibiotics in more than 50% of patients. In 37 hospitals that performed more than 5 LC per year, 19 to 100% of patients were given antibiotics. No surgical complications were identified in those who did not get antibiotics. CONCLUSION: There is significant inter-hospital variation in prophylactic antibiotic administration for elective LC in children. Perioperative antibiotic administration should be tracked as a quality metric in the current push for better stewardship. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Retrospective.

Do-not-resuscitate orders and high-risk pediatric surgery: professional nuisance or medical necessity?

BACKGROUND: There is a paucity of data in the literature regarding end-of-life care and do-not-resuscitate (DNR) status of the pediatric surgical patient, although invasive procedures are frequently performed in very high risk and critically ill children. Despite significant efforts in adult medicine to enhance discussions around end-of-life care, little is known about similar endeavors in the pediatric population. METHODS: A retrospective review of the National Surgical Quality Improvement Program Pediatric database was performed. Patients aged <18 y with American Society of Anesthesiologists class 3 or greater who underwent elective surgical procedure in 2012-2013 were included. Demographic factors, principal diagnosis, associated conditions, DNR status, and mortality were extracted. Descriptive analysis was performed. RESULTS: A total of 20,164 patients met the inclusion criteria. Only 36 (0.2%) patients had a signed DNR order before surgical procedure. Of severely ill American Society of Anesthesiologists four patients, only 1% had DNR status. There were no differences in gender, race, ethnicity, or surgical specialty by the presence of a DNR order. Notably, 17.1% of children who died within this period had multiple surgical procedures performed before expiring. CONCLUSIONS: The rate of documented DNR status is extremely low in the high-risk pediatric surgical population undergoing elective surgery, even among severely ill children. Well-informed end-of-life care discussions in a patient-focused approach are essential in the surgical care of children with complex medical conditions and critical illness. Better documentation of DNR discussion will also allow better tracking and benchmarking.

Race and socioeconomic disparities in national stoma reversal rates.

BACKGROUND: Many temporary stomas are never reversed leading to significantly worse quality of life. Recent evidence suggests a lower rate of reversal among minority patients. Our study aimed to elucidate disparities in national stoma closure rates by race, medical insurance status, and household income. METHODS: Five years of data from the Nationwide Inpatient Sample (2008 to 2012) was used to identify the annual rates of stoma formation and annual rates of stoma closure. Stomas labeled as "permanent" or those created secondary to colorectal cancers were excluded. Temporary stoma closure rates were calculated, and differences were tested with the chi-square test. Separate analyses were performed by race/ethnicity, insurance status, and household income. Nationally representative estimates were calculated using discharge-level weights. RESULTS: The 5-year average annual rate of temporary stoma creation was 76,551 per year (46% colostomies and 54% ileostomies). The annual rate of stoma reversal was 50,155 per year that equated to an annual reversal rate of 65.5%. Reversal rates were higher among white patients compared with black patients (67% vs 56%, P < .001) and among privately insured patients compared with uninsured patients (88% vs 63%, P < .001). Reversal rates increased as the household income increased from 61% in the lowest income quartile to 72% in the highest quartile (P < .001). CONCLUSIONS: Stark disparities exist in national rates of stoma closure. Stoma closure is associated with race, insurance, and income status. This study highlights the lack of access to surgical health care among patients of minority race and low-income status.
