Spare the Needle, Discharge the Child: Trending Post-Op Labs After Laparoscopic Common Bile Duct Exploration in Pediatric Patients Is Not Helpful

Laparoscopic common bile duct exploration (LCBDE) utility in management of choledocholithiasis may decrease length of stay and patient cost, but postoperative management remains widely debated. We examined periprocedural LFTs for patients undergoing LCBDE and endoscopic retrograde cholangiopancreatography (ERCP) speculating for trend existence after successful LCBDE. We hypothesized that postoperative LCBDE LFTs would not downtrend even after successful ductal clearance. We identified 99 patients under 18 who underwent ERCP or LCBDE with at least one pre- and post-procedural LFT. Periprocedural LFTs between groups were compared using Wilcoxon signed-rank tests. The 22 ERCP patients demonstrated a significant downtrend across Tbili (P < .001), AST (P = .001), ALT (P = .002), and ALP (P < .001). The 27 LCBDE patients demonstrated a significant downtrend in Tbili (P = .002) only, while AST (P > .05), ALT (P > .05), and ALP (P > .05) were nonsignificant. Lack of consistent downtrend in the LCBDE group raises doubt regarding the utility of postoperative LFTs for post-procedural management.

Prevalence and Outcomes of High versus Low Ratio Plasma to Red Blood Cell Resuscitation in a Multi-Institutional Cohort of Severely Injured Children

BACKGROUND

The benefit of targeting high ratio fresh frozen plasma (FFP):red blood cell (RBC) transfusion in pediatric trauma resuscitation is unclear as existing studies are limited to patients who retrospectively met criteria for massive transfusion. The purpose of this study is to evaluate the use of high ratio FFP:RBC transfusion and the association with outcomes in children presenting in shock.

METHODS

A post-hoc analysis of a 24-institution prospective observational study (4/2018-9/2019) of injured children <18 years with elevated age-adjusted shock index was performed. Patients transfused within 24 hours were stratified into cohorts of low (<1:2) or high (>1:2) ratio FFP:RBC. Nonparametric Kruskal-Wallis and chi-square were used to compare characteristics and mortality. Competing risks analysis was used to compare extended (≥75th percentile) ventilator, intensive care, and hospital days while accounting for early deaths.

RESULTS

Of 135 children with median (IQR) age 10 (5,14) years and weight 40 (20,64) kg, 85 (63%) received low ratio transfusion and 50 (37%) high ratio despite similar activation of institutional massive transfusion protocols (MTP; low-38%, high-46%, p = .34). Most patients sustained blunt injuries (70%). Median injury severity score was greater in high ratio patients (low-25, high-33, p = .01); however, hospital mortality was similar (low-24%, high-20%, p = .65) as was the risk of extended ventilator, ICU, and hospital days (all p > .05).

CONCLUSION

Despite increased injury severity, patients who received a high ratio of FFP:RBC had comparable rates of mortality. These data suggest high ratio FFP:RBC resuscitation is not associated with worst outcomes in children who present in shock. MTP activation was not associated with receipt of high ratio transfusion, suggesting variability in MTP between centers.

Storage Practices, Devices, and Presence of Children Among Owners of Firearms: Informing Pediatric Firearm Safety

BACKGROUND

Firearm injury is the leading cause of death in children and prevention is the most effective method to reduce severe morbidity and mortality. Injury prevention programs have used community firearm lock giveaway events to promote safe firearm storage practices. The locks are generally simple and inexpensive devices suitable for mass distribution but may not possess the owner-desired attributes for use in the home. Because data on owner preferences for firearm lock type is lacking, we conducted a community survey to inform firearm safety outreach efforts.

METHODS

We performed an anonymous cross-sectional survey at a large community fair. We elicited responses regarding reasons for firearm ownership, current storage practices, and preferences for firearm storage devices. Participants were offered a choice of a free trigger lock or cable lock and education on its use.

RESULTS

Two-hundred and sixty-seven of 394 (67.7%) respondents reported firearm ownership, with 64.8% reporting children in the home regularly. Most (60.7%) owned handguns and cited personal protection as the main reason for ownership (88.4%). The ability to store the firearm loaded and the need for rapid access were identified as the main storage considerations. Respondents preferred trigger locks over cable locks at a rate of almost 2:1.

CONCLUSIONS

The majority of firearm owners had handguns for self-defense. Owners preferred simple locking mechanisms that allowed the firearm to remain loaded. The pragmatic pediatric injury prevention program will include firearm owners' preferences when considering which lock to purchase and distribute during firearm injury prevention programs.

Raising the Bar: Multimodal Analgesia with Transdermal Lidocaine for Nuss Repair of Pectus Excavatum Decreases Length of Stay and Opioid Use

INTRO

Pain management for minimally invasive (Nuss) repair of pectus excavatum (PE) is challenging, particularly as the judicious use of opioids has become a patient safety priority. Multi-modal pain management protocols are increasingly used, but there is limited experience using transdermal lidocaine patches (TLP) in this patient population.

METHODS

Pediatric anesthesiologists and surgeons in a children's hospital within a hospital designed a multi-modal perioperative pain management protocol for patients undergoing Nuss repair of PE (IRB00068901). The protocol included use of TLP in addition to other adjuncts such as methadone, gabapentin, and NSAIDS. Following initiation of the protocol charts were reviewed retrospectively, comparing outcomes before and after implementation of the protocol.

RESULTS

Forty-nine patients underwent a Nuss procedure between 2013 and 2022, 15 prior to initiation of the protocol and 34 after. Patient demographics and operative length were similar between the two groups. Average length of stay decreased from 4.7 to 3.3 days and reported opioid use at the time of the first outpatient post-op visit dropped from 60% to 24% (p < 0.05). Morphine milligram equivalents (MME) usage was decreased following implementation during hospital admission, at discharge, and at first post-operative visit (464 vs. 169, 1288 vs. 218, and 214 vs. 56, respectfully, p < 0.05). There were no ED visits or readmissions <30 days related to post-operative pain.

CONCLUSION

Post-operative opioid usage and hospital length of stay were decreased after initiation of the protocol. Transdermal lidocaine patches may be a helpful adjunct to minimize narcotic requirements after repair of pectus excavatum.

Water Beads-Exploratory Learning or Exploratory Laparotomy?

Small brightly colored water beads have become increasingly popular toys in the pediatric population, marketed specifically for sensory exploration and learning. Unfortunately, the water-absorbing polymer which gives these toys their ability to grow also serves as means of obstruction if ingested. We report a case of a pediatric patient presenting with small bowel obstruction following the ingestion of a water bead, which was diagnosed and treated swiftly without complication. With the increasing incidence of water bead ingestion, it is essential that the public be aware of the potential risks and the necessity of seeking medical attention if companies do not withdraw such dangerous products from the market.

Crystalloid volume is associated with short-term morbidity in children with severe traumatic brain injury: An Eastern Association for the Surgery of Trauma multicenter trial post hoc analysis

OBJECTIVE

This study examined differences in clinical and resuscitation characteristics between injured children with and without severe traumatic brain injury (sTBI) and aimed to identify resuscitation characteristics associated with improved outcomes following sTBI.

METHODS

This is a post hoc analysis of a prospective observational study of injured children younger than 18 years (2018-2019) transported from the scene, with elevated shock index pediatric-adjusted on arrival and head Abbreviated Injury Scale score of ≥3. Timing and volume of resuscitation products were assessed using χ 2t test, Fisher's exact t test, Kruskal-Wallis, and multivariable logistic regression analyses.

RESULTS

There were 142 patients with sTBI and 547 with non-sTBI injuries. Severe traumatic brain injury patients had lower initial hemoglobin (11.3 vs. 12.4, p < 0.001), greater initial international normalized ratio (1.4 vs. 1.1, p < 0.001), greater Injury Severity Score (25 vs. 5, p < 0.001), greater rates of ventilator (59% vs. 11%, p < 0.001) and intensive care unit (ICU) requirement (79% vs. 27%, p < 0.001), and more inpatient complications (18% vs. 3.3%, p < 0.001). Severe traumatic brain injury patients received more prehospital crystalloid (25% vs. 15%, p = 0.008), ≥1 crystalloid boluses (52% vs. 24%, p < 0.001), and blood transfusion (44% vs. 12%, p < 0.001) than non-sTBI patients. Among sTBI patients, receipt of ≥1 crystalloid bolus (n = 75) was associated with greater ICU need (92% vs. 64%, p < 0.001), longer median ICU (6 vs. 4 days, p = 0.027) and hospital stay (9 vs. 4 days, p < 0.001), and more in-hospital complications (31% vs. 7.5%, p = 0.003) than those who received <1 bolus (n = 67). These findings persisted after adjustment for Injury Severity Score (odds ratio, 3.4-4.4; all p < 0.010).

CONCLUSION

Pediatric trauma patients with sTBI received more crystalloid than those without sTBI despite having a greater international normalized ratio at presentation and more frequently requiring blood products. Excessive crystalloid may be associated with worsened outcomes, including in-hospital mortality, seen among pediatric sTBI patients who received ≥1 crystalloid bolus. Further attention to a crystalloid sparing, early transfusion approach to resuscitation of children with sTBI is needed.

Making common duct exploration common-balloon sphincteroplasty as an adjunct to transcystic laparoscopic common bile duct exploration for pediatric patients

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) at the time of cholecystectomy has well-established benefits for managing pediatric choledocholithiasis. However, providers increasingly favor ERCP pre-or-post laparoscopic cholecystectomy (ERCP+LC) due to perceived complexity of LCBDE. We refined a stepwise method employing wire-ready balloon dilation of the Sphincter of Oddi. This study compares outcomes of balloon sphincteroplasty (LCBDE+BSP) with standard transcystic LCBDE (LCBDE-STD) and ERCP+LC.

METHODS

We performed a retrospective chart review of pediatric patients who underwent LCBDE-STD and LCBDE+BSP since 2018. A report of consecutive choledocholithiasis patients prior to 2018 yielded an ERCP+LC cohort. Age, operative time, complications, and length of stay (LOS) were compared across all groups. Success rate and fluoroscopy time were compared between LCBDE groups.

RESULTS

44 patients were identified (14:LCBDE-STD; 15:LCBDE+BSP; 15:ERCP+LC) . There was no difference in patient age or BMI. Operative time was longer in the LCBDE+BSP group (p =< 0.05). ERCP+LC demonstrated increased LOS (4.36 ± 2.78 vs 1.31 ± 0.93; p =< 0.05) and complications compared to LCBDE groups including three stent placements and one stent migration. LCBDE+BSP had a higher success rate than LCBDE-STD (100% vs 78%; p = 0.06). The three patients who failed LCBDE-STD required postoperative ERCP. Average fluoroscopy time was not significantly impacted by addition of sphincteroplasty.

CONCLUSION

Incorporating LCBDE into standard management of pediatric choledocholithiasis reduces LOS and avoids additional invasive procedures regardless of the specific technique employed. This stepwise approach to wire-ready cholangiography with balloon sphincteroplasty is a viable method for LCBDE that utilizes techniques familiar to pediatric surgeons and provides definitive management under a single anesthetic.

Balloon sphincteroplasty in pediatric laparoscopic common bile duct exploration

The management of choledocholithiasis in children and teenagers is often a two-procedure process with laparoscopic cholecystectomy (LC) and either pre- or post-operative endoscopic retrograde cholangiopancreatography (ERCP). The addition of laparoscopic common bile duct exploration (LCBDE) during LC can provide definitive treatment for choledocholithiasis during a single anesthetic event. In an effort to minimize sedation and radiation exposure from fluoroscopy, we have employed dilating balloons via a transcystic approach to stretch the sphincter of Oddi with subsequent ductal flushing. We describe the technique of balloon sphincteroplasty as a straightforward adjunct within the pediatric surgeon's skill set to manage choledocholithiasis during LC and our clinical experience.

Risks of venous thrombosis and bleeding in critically ill adolescents after trauma or major surgery

BACKGROUND

The risks of venous thromboembolism (VTE) and bleeding in critically ill adolescents based on interventions received and anatomic site of trauma or major surgery may identify a cohort eligible for enrollment in a trial of pharmacologic prophylaxis.

METHODS

This retrospective cohort study using the Virtual Pediatric Systems database included adolescents admitted to pediatric intensive care units after trauma or major surgery between 2013 and 2017. Mixed effects logistic regression was used to determine the adjusted risks of VTE and bleeding with central venous catheterization (CVC), mechanical ventilation (MV) and anatomic site of trauma or major surgery. The adjusted risks were used to identify the cohort eligible for enrollment.

MEASUREMENTS AND MAIN RESULTS

VTE developed in 212 (0.8%) of 27,647 adolescents. The adjusted risk of VTE was >2% with CVC and 2 or more of MV and trauma or major surgery to the brain or abdomen. Excluding those with bleeds present on admission or at high risk of bleeding, 375 (1.4%) adolescents would be eligible for enrollment.

CONCLUSIONS

VTE is generally uncommon in adolescents after trauma or major surgery. The small proportion of adolescents who are at high risk of VTE and at low risk of bleeding impacts the feasibility of a trial.

Evaluation of an evidence-based guideline to reduce CT use in the assessment of blunt pediatric abdominal trauma

PURPOSE

About half of pediatric blunt trauma patients undergo an abdominopelvic computed tomographic (CT) scan, while few of these require intervention for an intraabdominal injury. We evaluated the effectiveness of an evidence-based guideline for blunt abdominal trauma at a Level I pediatric trauma center.

METHODS

Pediatric blunt trauma patients (n = 998) age 0-15 years who presented from the injury scene were evaluated over a 10 year period. After five years, we implemented our guideline in which the decision for CT was standardized based on mental status, abdominal examination, and laboratory results (alanine aminotransferase, aspartate aminotransferase, hemoglobin, urinalysis).

RESULTS

There were no differences in age, GCS, SIPA or ISS scores between the patients before or after guideline implementation. Nearly half of the patients (48.3%) underwent CT scan before guideline implementation compared to 36.7% after (p < 0.0002). There was no difference in ISS (p = 0.44) between CT scanned patients in either group. No statistical differences were found in rate of intervention (p = 0.20), length of stay (p = 0.65), or readmission rate (0.2%) before versus after guideline implementation. There were no missed injuries.

CONCLUSION

Implementation of an evidence-based clinical guideline for pediatric patients with blunt abdominal trauma decreases the rate of CT utilization while accurately identifying significant injuries.

Bronchial Blocker Entrapment in a 7-Month-Old Infant: A Case Report

We present the case of a 7-month-old infant undergoing thoracotomy and left lower lobe lobectomy who experienced a significant complication related to lung isolation with a bronchial blocker. Despite good isolation and seemingly appropriate positioning, the bronchial blocker became entrapped within the staple line at the bronchial stump. Fortunately, the surgeon was able to free the blocker. Going forward, we recommend clinicians be vigilant in positioning the blocker just distal to the carina in all cases and, further, consider retracting the blocker into the trachea before surgical intervention on the airway to avoid inadvertent entrapment of the device.

Non-operative management of solid organ injuries in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee systematic review

PURPOSE

The American Pediatric Surgical Association (APSA) guidelines for the treatment of isolated solid organ injury (SOI) in children were published in 2000 and have been widely adopted. The aim of this systematic review by the APSA Outcomes and Evidence Based Practice Committee was to evaluate the published evidence regarding treatment of solid organ injuries in children.

METHODS

A comprehensive search strategy was crafted and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Four principal questions were examined based upon the previously published consensus APSA guidelines regarding length of stay (LOS), activity level, interventional radiologic procedures, and follow-up imaging. A literature search was performed including multiple databases from 1996 to 2016.

RESULTS

LOS for children with isolated solid organ injuries should be based upon clinical findings and may not be related to grade of injury. Total LOS may be less than recommended by the previously published APSA guidelines. Restricting activity to grade of injury plus two weeks is safe but shorter periods of activity restriction have not been adequately studied. Prophylactic embolization of SOI in stable patients with image-confirmed arterial extravasation is not indicated and should be reserved for patients with evidence of ongoing bleeding. Routine follow-up imaging for asymptomatic, uncomplicated, low-grade injured children with abdominal blunt trauma is not warranted. Limited data are available to support the need for follow-up imaging for high grade injuries.

CONCLUSION

Based upon review of the recent literature, we recommend an update to the current APSA guidelines that includes: hospital length of stay based on physiology, shorter activity restrictions may be safe, minimizing post-injury imaging for lower injury grades and embolization only in patients with evidence of ongoing hemorrhage.

Firearm Injuries and Children: Position Statement of the American Pediatric Surgical Association

Firearm injuries are the second most common cause of death in children who come to a trauma center, and pediatric surgeons provide crucial care for these patients. The American Pediatric Surgical Association (APSA) is committed to comprehensive pediatric trauma readiness, including firearm injury prevention. The APSA supports a public health approach to firearm injury, and it supports availability of quality mental health services. The APSA endorses policies for universal background checks, restrictions on assault weapons and high-capacity magazines, strong child access protection laws, and a minimum purchase age of 21 years. The APSA opposes efforts to keep physicians from counseling children and families about firearms. The APSA promotes research to address this problem, including increased federal research support and research into the second victim phenomenon. The ASPA supports school safety and readiness, including bleeding control training. Although it may be daunting to try to reduce firearm deaths in children, the United States has seen success in reducing motor vehicle deaths through a multidimensional approach: prevention, design, policy, behavior, and trauma care. The ASPA believes that a similar public health approach can succeed in saving children from death and injury from firearms. The ASPA is committed to building partnerships to accomplish this.

“A-OK”: Chest Radiograph during Primary Survey Facilitates Faster, More Accurate Endotracheal Tube Position in Injured Children

The Advanced Trauma Life Support algorithm recommends bedside confirmatory techniques to confirm correct endotracheal tube (ETT) depth, a critical component in the care of pediatric trauma patients. We hypothesized that bedside confirmatory techniques are inaccurate and that early chest X-ray (CXR) would overcome such inaccuracies, allowing for faster intervention of malpositioned ETTs. An “A-OK” algorithm of immediate CXR following intubation in injured children aged <16 years was implemented. Eligible patients the years before and after implementation were identified. The accuracy of bedside confirmatory techniques (use of length-based depths and auscultation of breath sounds) was assessed. Post-“A-OK” patients were compared with pre-“A-OK” controls regarding the speed of malpositioned ETTrepositioning. Twenty-eight post-“A-OK” cases and 23 pre-“A-OK” controls were identified. The groups did not differ in baseline characteristics. Bedside confirmatory techniques were accurate in only 61 per cent (length-based depth) and 58 per cent (auscultation of breath sounds) of patients. Time to ETT repositioning was significantly longer in pre-“A-OK” controls than in post-“A-OK” cases (35.2 ± 15.9 minutes vs 21.1 ± 11.8 minutes, P = 0.03). Bedside confirmatory techniques to determine ETT positioning are inaccurate in children. Inclusion of CXR in the primary survey is safe and allows for more rapid repositioning of malpositioned ETTs.

Characterization of the occult nature of frequently occurring pediatric motor vehicle crash injuries

BACKGROUND

Occult injuries are those likely to be missed on initial assessment by first responders and, though initially asymptomatic, they may present suddenly and lead to rapid patient decompensation. No scoring systems to quantify the occultness of pediatric injuries have been established. Such a scoring system will be useful in the creation of an Advanced Automotive Crash Notification (AACN) system that assists first responders in making triage decisions following a motor vehicle crash (MVC).

STUDY DESIGN

The most frequent MVC injuries were determined for 0-4, 5-9, 10-14 and 15-18 year olds. For each age-specific injury, experts with pediatric trauma expertise were asked to rate the likelihood that the injury may be missed by first responders. An occult score (ranging from 0-1) was calculated by averaging and normalizing the responses of the experts polled.

RESULTS

Evaluation of all injuries across all age groups demonstrated greater occult scores for the younger age groups compared to older age groups (mean occult score 0-4yo: 0.61 ± 0.23, 5-9yo: 0.53 ± 0.25, 10-14yo: 0.48 ± 0.23, and 15-18yo: 0.42 ± 0.22, p < 0.01). Body-region specific occult scores revealed that experts judged abdominal, spine and thoracic injuries to be more occult than injuries to other body regions.

CONCLUSIONS

The occult scores suggested that injuries are more difficult to detect in younger age groups, likely given their inability to express symptoms. An AACN algorithm that can predict the presence of clinically undetectable injuries at the scene can improve triage of children with these injuries to higher levels of care.

Predicting Pediatric Patients Who Require Care at a Trauma Center: Analysis of Injuries and Other Factors

BACKGROUND

Triage decision correctness for children in motor vehicle crashes can be affected by occult injuries. There is a need to develop a transfer score (TS) metric for children that can help quantify the likelihood that an injury is present that would require transfer to a trauma center (TC) from a non-TC, and improve triage decision making. Ultimately, the TS metric might be useful in an advanced automatic crash notification algorithm, which uses vehicle telemetry data to predict the risk of serious injury after a motor vehicle crash using an approach that includes metrics to describe injury severity, time sensitivity, and predictability.

STUDY DESIGN

Transfer score metrics were calculated in 4 pediatric age groups (0 to 4, 5 to 9, 10 to 14, 15 to 18 years) for the most frequent motor vehicle crash injuries using the proportions of children transferred to a TC or managed at a non-TC using the National Inpatient Sample years 1998 to 2007. To account for the maximum Abbreviated Injury Scale (MAIS) injury, a co-injury adjusted transfer score (TS_MAIS) was calculated. The TS and TS_MAIS range from 0 to 1, with 1 indicating highly transferred injuries.

RESULTS

Injuries in younger patients were more likely to be transferred (median TS 0.48, 0.35, 0.25, and 0.23 for 0 to 4, 5 to 9, 10 to 14, and 15 to 18 years, respectively). Injuries more likely to be transferred in younger children occurred in the thorax and abdomen. Regardless of age, spine (median TS_MAIS 0.59), head (median TS_MAIS 0.48), and thorax (median TS_MAIS 0.46) injuries had the highest frequency for transfer.

CONCLUSIONS

The TS metrics quantitatively describe age-specific transfer practices for children with particular injuries. This information can be useful in advanced automatic crash notification systems to alert first responders to the possibility of occult injuries and reduce undertriage of commonly missed injuries.

Expert Perspectives on Time Sensitivity and a Related Metric for Children Involved in Motor Vehicle Crashes

OBJECTIVE

Advanced Automatic Crash Notification (AACN) uses vehicle telemetry data to predict risk of serious injury among motor vehicle crash occupants and can thus improve the accuracy with which injured children are triaged by first responders. To better define serious injury for AACN systems (which typically use Abbreviated Injury Scale [AIS] metrics), an age-specific approach evaluating severity, time sensitivity (TS), and predictability of injury has been developed. This study outlines the development of the TS score.

METHODS

The 95% most frequent AIS 2+ injuries in a national motor vehicle crash data set spanning 2000 to 2011 were determined for the following age groups: 0 to 4, 5 to 9, 10 to 14, and 15 to 18 years. For each age-specific injury, clinicians with pediatric trauma expertise were asked if treatment at a trauma center was required and were asked about the urgency of treatment. A TS score (range 0-1) was calculated by combining the mean trauma center decision and urgency scores.

RESULTS

A total of 30 to 32 responses were obtained for each age-specific injury. The most frequent motor vehicle crash-induced injuries in the younger groups received significantly higher scores than those in the older groups (median TS score 0 to 4 years: 0.89, 5-9 years: 0.87, 10-14 years: 0.82, 15-18 years: 0.72, P < .001). Large variations in TS existed within each AIS severity level; for example, scores among AIS 2 injuries in 0- to 4-year-olds ranged from 0.12 to 0.98.

CONCLUSIONS

The TS of common pediatric injuries varies on the basis of age and may not be accurately reflected by AIS metrics. AIS may not capture all aspects of injury that should be considered by AACN systems.

Venous thromboembolism prophylaxis in the pediatric trauma patient

Although venous thromboembolism (VTE) occurs in less than 1% of hospitalized pediatric trauma patients, care providers must make decisions about VTE prophylaxis on a daily basis. The consequences of VTE are significant; the risks of developing VTE are variable; and the effectiveness of prophylaxis against VTE is not conclusive in children. While the value of VTE prophylaxis is well defined in adult trauma care, it is unclear how this translates to the care of injured children. This review evaluates the incidence and risks of VTE in pediatric trauma and assesses the merits of prophylaxis in children. Pharmacologic prophylaxis against VTE is a reasonable strategy in critically injured adolescent trauma patients. Further study is needed to establish the risks and benefits of VTE prophylaxis across the spectrum of injured children.

Mortality Risk in Pediatric Motor Vehicle Crash Occupants: Accounting for Developmental Stage and Challenging Abbreviated Injury Scale Metrics

OBJECTIVE

Survival risk ratios (SRRs) and their probabilistic counterpart, mortality risk ratios (MRRs), have been shown to be at odds with Abbreviated Injury Scale (AIS) severity scores for particular injuries in adults. SRRs have been validated for pediatrics but have not been studied within the context of pediatric age stratifications. We hypothesized that children with similar motor vehicle crash (MVC) injuries may have different mortality risks (MR) based upon developmental stage and that these MRs may not correlate with AIS severity.

METHODS

The NASS-CDS 2000-2011 was used to define the top 95% most common AIS 2+ injuries among MVC occupants in 4 age groups: 0-4, 5-9, 10-14, and 15-18 years. Next, the National Trauma Databank 2002-2011 was used to calculate the MR (proportion of those dying with an injury to those sustaining the injury) and the co-injury-adjusted MR (MRMAIS) for each injury within 6 age groups: 0-4, 5-9, 10-14, 15-18, 0-18, and 19+ years. MR differences were evaluated between age groups aggregately, between age groups based upon anatomic injury patterns and between age groups on an individual injury level using nonparametric Wilcoxon tests and chi-square or Fisher's exact tests as appropriate. Correlation between AIS and MR within each age group was also evaluated.

RESULTS

MR and MRMAIS distributions of the most common AIS 2+ injuries were right skewed. Aggregate MR of these most common injuries varied between the age groups, with 5- to 9-year-old and 10- to 14-year-old children having the lowest MRs and 0- to 4-year-old and 15- to 18-year-old children and adults having the highest MRs (all P <.05). Head and thoracic injuries imparted the greatest mortality risk in all age groups with median MRMAIS ranging from 0 to 6% and 0 to 4.5%, respectively. Injuries to particular body regions also varied with respect to MR based upon age. For example, thoracic injuries in adults had significantly higher MRMAIS than such injuries among 5- to 9-year-olds and 10- to 14-year-olds (P =.04; P <.01). Furthermore, though AIS was positively correlated with MR within each age group, less correlation was seen for children than for adults. Large MR variations were seen within each AIS grade, with some lower AIS severity injuries demonstrating greater MRs than higher AIS severity injuries. As an example, MRMAIS in 0- to 18-year-olds was 0.4% for an AIS 3 radius fracture versus 1.4% for an AIS 2 vault fracture.

CONCLUSIONS

Trauma severity metrics are important for outcome prediction models and can be used in pediatric triage algorithms and other injury research. Trauma severity may vary for similar injuries based upon developmental stage, and this difference should be reflected in severity metrics. The MR-based data-driven determination of injury severity in pediatric occupants of different age cohorts provides a supplement or an alternative to AIS severity classification for pediatric occupants in MVCs.

Pediatric child abuse victim with posttraumatic inferior vena cava thrombosis

Posttraumatic inferior vena cava thrombosis (IVCT) is very rare, with only a few cases reported in the literature. While thromboembolism as a result of trauma is common in adult patients, it is very rare in young children and seldom involves the inferior vena cava. We report the youngest patient to date with IVCT and the only child reported whose findings are the result of child physical abuse. The diagnosis can be challenging both clinically and radiographically. Additionally, the risks of morbidity and even mortality associated with an IVCT if untreated are significant.

A novel antireflux procedure: gastroplasty with restricted antrum to control emesis (GRACE)

PURPOSE

Nissen fundoplication is the most commonly performed operation to treat gastroesophageal reflux disease and vomiting in children with neurologic impairment. However, failure rates of Nissen fundoplication in this population are higher, and alternatives to Nissen fundoplication have technical and functional disadvantages. We hypothesize that the novel gastroplasty with restricted antrum to control emesis (GRACE) would be more effective than Nissen fundoplication at reducing emetic reflux.

METHODS

To compare the GRACE with Nissen fundoplication, 15 canine subjects were randomized to Nissen fundoplication or GRACE. All subjects underwent gastrostomy tube placement. Baseline gastric emptying, electrogastrography, and induced vomiting studies were performed. Nissen fundoplication or GRACE was then performed. Postoperatively, gastric emptying and vomiting studies were repeated.

RESULTS

Gastric emptying before and after antireflux procedures was not significantly different between groups. Both Nissen fundoplication (38%, P = .04) and GRACE (69%, P < .01) procedures prevented reflux compared with baseline. However, the GRACE procedure significantly reduced reflux when compared with Nissen fundoplication (P = .03).

CONCLUSIONS

In this canine model, GRACE appears to be significantly more effective than Nissen fundoplication at reducing emetic reflux. This novel procedure preserves gastric function and is well tolerated. The GRACE procedure may provide an alternative to Nissen fundoplication as a primary or repeat antireflux procedure for children with neurologic impairment.

Microlithiasis, endoscopic ultrasound, and children: not just little gallstones in little adults

PURPOSE

Biliary microlithiasis is an uncommon but recognized cause of upper abdominal pain, cholecystitis, cholangitis, and pancreatitis in adults. Gallstones smaller than 3 mm may not be seen on transabdominal ultrasound and may only be seen on endoscopic ultrasound. This condition is poorly described in children. The aim of this study is to review the results of laparoscopic cholecystectomy to treat biliary microlithiasis in a pediatric case series.

METHODS

We performed a retrospective case review of children with biliary microlithiasis who were treated with laparoscopic cholecystectomy.

RESULTS

Three children were diagnosed with biliary microlithiasis. Two patients had recurrent right upper quadrant pain and nausea. A third patient had midepigastric pain and idiopathic pancreatitis. All 3 had a normal gallbladder on transabdominal ultrasound. Additional imaging with hepatobiliary scan, computed tomography, and magnetic resonance cholangiopancreatography revealed no biliary source for symptoms. Endoscopic ultrasound was performed on all 3 children, demonstrating microlithiasis of the gallbladder. Each child had a laparoscopic cholecystectomy with intraoperative cholangiogram. No abnormalities were seen on intraoperative cholangiogram. All 3 children had alleviation of pain and improvement of symptoms in postoperative follow-up.

CONCLUSION

Children with biliary microlithiasis and associated clinical symptoms can be successfully treated with laparoscopic cholecystectomy. Endoscopic ultrasound should be considered in the evaluation of the child with clinical biliary symptoms and a negative transabdominal ultrasound result.

Familial small cell carcinoma of the ovary

Ovarian tumors have a low incidence in childhood, accounting for 1% of malignancies within the ages of 0-17 years. Small cell carcinoma of the ovary is a rare histology and historically has a poor prognosis. We report a case of an 11-year-old female diagnosed with small cell carcinoma of the ovary and hypercalcemia (SCCOHT). There was a strong family history of the disease, a reduction in the age of onset in the proband, and the absence of BRCA mutations. This case suggests the phenomenon of genetic anticipation in an ovarian cancer.

A unique case of a giant congenital pulmonary hemangioma in a newborn

Congenital pulmonary hemangiomas are extremely rare lesions. We present a unique case of a giant congenital pulmonary hemangioma in an otherwise healthy newborn who presented with respiratory distress at birth. This was managed with resection after an unsuccessful trial of nonoperative management. The clinical, radiographic, and pathologic features of this unique case are discussed in the context of a review of the literature.

Resection of Neurogenic Tumors in Children: Is Thoracoscopy Superior to Thoracotomy?

BACKGROUND

Minimally invasive resection of solid tumors is controversial because of concerns of inadequate resection and local recurrence. Thoracoscopy has been used in the diagnosis of mediastinal tumors in children, but its role in resection is unproved. The purpose of this study was to compare thoracoscopic and open approaches to the resection of thoracic neurogenic tumors in children.

STUDY DESIGN

The tumor registry of a regional children's hospital was queried to identify patients who underwent resection of neurogenic tumors over a 6-year period. Thoracoscopic and open groups were compared for demographic, operative, oncologic, and outcomes characteristics.

RESULTS

Seventeen children underwent resection of mediastinal neurogenic tumors (10 thoracoscopic resections, 7 open resections). Mean age was 4.7 years (range 6 months to 12 years). The thoracoscopic and open groups showed no difference in operative time or blood loss. Tumors in the two groups were comparable in size (5.2+/-2.2 cm versus 5.7+/-2.6 cm), histology, surgical margin, and stage. Hospital stay was shorter after thoracoscopic resection (1.9+/-0.7 days versus 4.1+/-2.5 days, p<0.05). There were no regional recurrences. Distant metastases developed in one patient in each group. Eight of 10 children with malignant tumors remain disease-free at an average of 25 months of followup (range 3 to 80 months).

CONCLUSIONS

Thoracoscopic resection of neurogenic tumors achieved similar local control and disease-free survival when compared with open resection in this preliminary series. These results were accompanied by a shorter hospital stay. These findings suggest that thoracoscopic resection of neurogenic tumors in children may offer advantages to open resection and should be studied in the context of a large, cooperative trial.

Laparoscopic guidance or revision of ventriculoperitoneal shunts in children

BACKGROUND

Ventriculoperitoneal shunt is the preferred treatment for hydrocephalus. Known complications include infection, obstruction, and disconnection with the fractured fragment migrating in the peritoneal cavity. We report 17 cases of laparoscopic evaluation and revision of ventriculoperitoneal shunts in children.

METHODS

From January 2000 through October 2002, we retrospectively reviewed our experience with laparoscopy and ventriculoperitoneal shunts.

RESULTS

Laparoscopy was performed in 17 children with a malfunctioning shunt, presumed shunt dislodgment or disconnection, reinsertion of a shunt after externalization, and primary shunt placement. Six patients (35%) were converted to an open laparotomy due to dense adhesions. Eleven patients (65%) underwent successful laparoscopic-assisted ventriculoperitoneal shunt placement: 5/11 (45%) had lysis of adhesions or pseudocyst marsupialization with repositioning of a functional shunt, or both; 3/11 (27%) had successful retrieval of a disconnected catheter with reinsertion of a new catheter; 2/11 (18%) had laparoscopic confirmation of satisfactory placement and function, requiring no revision; 1/11 (9%) had an initial shunt placed with laparoscopic guidance due to the obesity. Operative time for the laparoscopic procedure ranged from 30 minutes to 60 minutes. All laparoscopic procedures used 1-mm or two 5-mm ports. Perioperatively, no adverse neurological sequelae occurred due to the pneumoperitoneum.

CONCLUSIONS

Laparoscopic guidance or revision of ventriculoperitoneal shunts permits (1) direct visualization of catheter insertion within the peritoneal cavity, (2) satisfactory positioning, (3) lysis of adhesions or marsupialization with catheter repositioning, or both, and (4) retrieval of fractured catheters.

Preservation of an aberrant left hepatic artery during laparoscopic nissen fundoplication

OBJECTIVE

Laparoscopic Nissen fundoplication is performed in neonates and children for significant gastroesophageal reflux. An aberrant left hepatic artery encountered during laparoscopic Nissen fundoplication makes dissection around the esophageal hiatus more difficult if the artery is not transected. Although some suggest division of the aberrant left hepatic artery, this is associated with risk of significant hepatic injury from ischemia. We routinely preserve the aberrant left hepatic artery and sought to determine (1) the incidence of aberrant left hepatic artery and (2) the results following preservation of the aberrant left hepatic artery.

METHODS

Between January 2000 and October 2002, 195 laparoscopic Nissen fundoplications were performed. We documented intraoperative findings of each procedure, and reviewed postoperative radiographic studies and clinic visits.

RESULTS

In 30 patients (15%), an aberrant left hepatic artery was identified. All dissections were performed laparoscopically with the Nissen fundoplication positioned cephalad to the aberrant left hepatic artery. Postoperatively, 2 patients (6%) have had evidence of wrap failure. The remainder of the patients has had normal radiographic studies or no clinical evidence of reflux during clinic visits.

CONCLUSION

During laparoscopic Nissen fundoplication in neonates and children, an aberrant left hepatic artery may be encountered in approximately 15% of patients. When an aberrant left hepatic artery is identified, it should be preserved to avoid the potential risk of hepatic ischemic injury.

Operative strategies for necrotizing enterocolitis: The prevention and treatment of short-bowel syndrome

Necrotizing enterocolitis (NEC) is the leading cause of short-bowel syndrome (SBS) in infancy. Studies on the acute medical and surgical management of NEC have traditionally focused on short-term morbidity and mortality, with less emphasis on long-term outcomes. Acute surgical management of NEC involves the often competing priorities of controlling sepsis and preserving bowel length. Bowel-preserving strategies for NEC, designed to limit SBS, are based on peritoneal drainage, limited resection, or a combination of both. Drainage-based strategies are generally favored in smaller neonates, while laparotomy-based strategies are favored in larger patients, especially those with a more limited extent of intestinal injury. Comparisons of drainage-based approaches and resection-based approaches are limited by confounding variables, and neither approach is clearly superior with regard to subsequent SBS. These traditional as well as more creative approaches to bowel preservation have application in NEC, yet they depend on a series of patient and treatment characteristics that include the ability of diseased but viable bowel to recover both absorptive and motility function after acute NEC, the ability of the infant to tolerate appropriately drained intraperitoneal contamination, and the ability of the injured intestine to subsequently undergo intestinal adaptive change. In addition, there are a series of operative options that have been designed to mitigate the impact of SBS once it is established. These procedures are not uniquely applied exclusively for NEC-induced SBS. However, strategies that slow intestinal transit, improve peristaltic function, or enhance mucosal absorptive function each have application in the management of SBS.

Laparoscopic-assisted percutaneous endoscopic gastrostomy in children and adolescents

OBJECTIVE

Pediatric gastric access for long-term enteral feeding may be performed via a laparotomy, laparoscopy, or a percutaneous approach. In children and adolescents, laparoscopic-assisted gastrostomy may be difficult due to a thick abdominal wall. Therefore, if the abdominal wall is estimated to be >2 cm on physical examination, or in children in whom a percutaneous endoscopic gastrostomy was unsuccessfully attempted by a gastroenterologist, we routinely perform a laparoscopic-assisted percutaneous endoscopic gastrostomy.

METHODS

From January 1998 through February 2003, we retrospectively reviewed 15 cases of a laparoscopic-assisted percutaneous endoscopic gastrostomy. Instruments used to perform this technique are a percutaneous endoscopic gastrostomy kit, an Olympus flexible endoscope, and one 5-mm STEP port placed through an infraumbilical incision for a 5-mm, 30-degree scope.

RESULTS

Age range was 2 years to 20 years (mean, 10). Operative time ranged from 20 minutes to 45 minutes. When a concurrent laparoscopic Nissen fundoplication was performed (n = 6), the percutaneous endoscopic gastrostomy was placed after completion of the Nissen fundoplication. No intraoperative complications occurred, and all tubes were successfully placed. Feeds were instituted the following day and advanced to goal. To date, no postoperative complications have occurred, and revision has not been necessary.

CONCLUSIONS

Laparoscopic-assisted percutaneous endoscopic gastrostomy in children and adolescents is safe and effective. Utilizing laparoscopy permits evaluation of the peritoneum and lysis of adhesions, if necessary. Moreover, laparoscopy provides excellent exposure for accurate placement of the PEG, while avoiding injury to other organs.

Early experience with laparoscopic pyloromyotomy in a teaching institution

OBJECTIVE

Hypertrophic pyloric stenosis is a common pediatric surgical condition. A Ramstedt pyloromyotomy is performed either via laparotomy or laparoscopy. We report our first 25 cases of laparoscopic pyloromyotomy at an academic children's hospital.

METHODS

From January 2002 through February 2003, we retrospectively reviewed our first 25 laparoscopic pyloromyotomies. All patients had documented hypertrophic pyloric stenosis by ultrasound criteria. Three incisions were made, one 5-mm umbilical port, one 3-mm right upper quadrant port, and a third left upper quadrant working stab incision. A 4-mm, 30 degrees scope was used in all cases. A longitudinal pyloromyotomy was performed using an arthrotomy scalpel. The pylorus was further separated with a laparoscopic Benson spreader. At the completion of the pyloromyotomy, the stomach was insufflated with air to identify any mucosal injury.

RESULTS

Age range was 2.3 weeks to 8.4 weeks. Operating time has decreased from 70 minutes to 15 minutes. Two conversions to an open procedure were necessary, both during the first 10 cases. No mucosal perforations or incomplete pyloromyotomies have occurred. Feeds were started within 4 hours and advanced to goal. Time to discharge ranged from 12 hours to 30 hours. One patient developed umbilical cellulitis that was successfully treated with antibiotics.

CONCLUSIONS

Laparoscopic pyloromyotomy is a safe, effective procedure for hypertrophic pyloric stenosis in a resident teaching environment. Laparoscopy permits excellent visualization, has comparable postoperative recovery, and superior cosmesis.

A new score for the evaluation of palpable breast masses in women under age 40

BACKGROUND

The purpose of this study was to develop a rapid and accurate diagnostic test for palpable breast masses in women under age 40.

METHODS

Masses were evaluated utilitzing a modified triple test score (MTTS), which assigned scores of 1 point for benign, 2 points for suspicious, or 3 points for malignant findings from physical examination, ultrasonography, and fine needle aspiration. The MTTS was the sum of the three scores and was correlated with biopsy or follow-up.

RESULTS

Among 113 masses, 100 scored 3 points, 8 scored 4 points; all were benign. Three scored 5 points; 1 was malignant. Two scored >or=6 points: both were malignant.

CONCLUSIONS

The MTTS has 100% diagnostic accuracy when other than 5 points. Masses scoring <or=4 points are benign. Masses scoring >or=6 points may proceed to definitive therapy. Masses scoring 5 points (3%) require biopsy. This approach avoids open biopsy in the majority of cases, while capturing all malignancies.

Survival in human colorectal cancer correlates with expression of the T-cell costimulatory molecule OX-40 (CD134)

BACKGROUND

The T-cell costimulatory molecule OX-40 (CD134) is expressed on activated CD4(+) ("helper") T cells. Such cells have been detected in human cancers, and engagement of OX-40 improves colon cancer immunity in an animal model.

METHODS

Sections of primary colon cancers, normal margins, mesenteric lymph nodes, and metastases were stained for OX-40 by immunohistochemistry. Cancer registry data were reviewed.

RESULTS

High levels of OX-40 positive tumor-infiltrating lymphocytes were found in 15 of 72 primary tumors. Thirty-one cases had prominent lymphocytic infiltrates expressing OX-40 at the invasive margin of the tumor. Overall, 50% of primary tumors showed high expression of OX-40. Nearly all mesenteric lymph nodes expressed OX-40, whether tumor was present or not. Normal margins of colon did not show high levels of OX-40. High OX-40 expression in the primary tumor correlated with better survival (mean survival high OX-40, 47 months, low OX-40, 35 months, P <0.05), although this correlation was not stage-independent.

CONCLUSIONS

High levels of OX-40 positive lymphocytes are present in half of primary colon cancers, and this expression in primary tumors significantly correlates with better survival. This correlation with survival and our previous preclinical research suggest a basis for an OX-40 immunotherapy trial.

Structured clinical breast examination (CBE) training results in objective improvement in CBE skills

BACKGROUND

A statewide breast cancer care provider needs assessment had identified CBE training as a target educational need. Accordingly, the authors implemented a one-on-one skills-based course for primary care providers (PCPs) across the state.

METHOD

The course had two components: a prerequisite self-study manual, followed by a 1 1/2-hour skills-based practicum. As part of the practicum, pre- and post-course testing were performed on standardized silicone breast models.

RESULTS

Pre- and post-testing data were available for 205 PCPs who completed the course. In the pre-test period, 59% of PCPs examined could detect 60-100% of the lumps. In the post-test, that rose to 94% of PCPs detecting 60-100% of the lumps. This improvement reached statistical significance. Further, false-positive lump detection declined in the post-test period to 59% of the pre-test rate (236 to 139).

CONCLUSION

Formal CBE training for PCPs significantly improves the sensitivity of lump detection and concurrently reduces false-positive detection. The program is currently being extended to a greater number of providers across the state.

Beyond doughnuts: tumor board recommendations influence patient care

BACKGROUND

There is little solid evidence to support the belief that tumor conferences directly impact the care patients receive. This study investigated the recommendations made at tumor conferences and whether these recommendations were enacted.

METHODS

Cancer registrars from Oregon-area hospitals with tumor boards that utilized a prospective "working" format were surveyed regarding tumor board characteristics and content. They also recorded the recommendations made for each prospective case presented at each tumor board for one month. Later, they contacted each patient's provider to see which recommendations had been implemented.

RESULTS

Information from eight tumor boards in six hospitals was recorded. The institutions varied with regard to size, location, number of tumor boards, number of cases reviewed annually, and types of cancers reviewed. One hundred fifty-three specific, prospective recommendations were made for the care of 97 patients. Of these, 128 (84%) were followed, 2 (1%) were pending, and 5 (3%) were status unknown. Of recommendations followed, 21 (16%) were for diagnosis, 100 (78%) were for therapy, and 7 (5%) were for palliation.

CONCLUSION

Recommendations made at tumor conferences are generally implemented into patient care. Tumor boards can play a strategic role in the planning of care for cancer patients.
