Implementation of an evidence-based accelerated pathway: can hospital length of stay for children with blunt solid organ injury be safely decreased?

BACKGROUND: Recent work has demonstrated that an accelerated pathway for pediatric patients with blunt solid organ injuries is safe; however, this is not well-studied in a dual trauma center. We hypothesized that implementation of an accelerated pathway would decrease length of stay (LOS) and hospitalization cost without increased mortality. METHODS: Retrospective review of patients < 15 years presenting to a dual level 1 trauma center between 2015 and 2020 with traumatic blunt liver and splenic injuries. Patients presenting pre- and post-protocol implementation were compared. The primary outcome was total hospital LOS. Secondary outcomes were number of lab draws, intensive care unit (ICU) LOS, cost of hospitalization, readmissions within 30 days, and mortality. RESULTS: 103 patients were evaluated, 67 pre-protocol and 63 post-protocol. LOS was significantly shorter post-protocol (2 days vs. 4 days, p < 0.001). The ICU LOS was unchanged. There was a decrease in direct hospitalization cost per patient from $6,246 pre-protocol to $4,294 post-protocol (p = 0.001). There was one readmission post-protocol and none pre-protocol. There were no deaths. CONCLUSION: Implementation of an accelerated pathway for management of blunt solid organ injury at a dual trauma center was associated with decreased LOS and decreased costs with no increased morbidity or mortality.

Causes of early mortality in pediatric trauma patients.

BACKGROUND: Trauma is the leading cause of death in children, and most deaths occur within 24 hours of injury. A better understanding of the causes of death in the immediate period of hospital care is needed. METHODS: Trauma admissions younger than 18 years from 2009 to 2019 at a Level I pediatric trauma center were reviewed for deaths (n = 7,145). Patients were stratified into ages 0-6, 7-12, and 13-17 years old. The primary outcome was cause of death, with early death defined as less than 24 hours after trauma center arrival. RESULTS: There were 134 (2%) deaths with a median age of 7 years. The median time from arrival to death was 14.4 hours (interquartile range, 0.5-87.8 hours). Half (54%) occurred within 24 hours. However, most patients who survived initial resuscitation in the emergency department died longer than 24 hours after arrival (69%). Traumatic brain injury was the most common cause of death (66%), followed by anoxia (9.7%) and hemorrhage (8%). Deaths from hemorrhage were most often in patients sustaining gunshot wounds (73% vs. 11% of all other deaths, p < 0.0001), more likely to occur early (100% vs. 50% of all other deaths, p = 0.0009), and all died within 6 hours of arrival. Death from hemorrhage was more common in adolescents (21.4% of children aged 13-17 vs. 6.3% of children aged 0-6, and 0% of children aged 7-12 p = 0.03). The highest case fatality rates were seen in hangings (38.5%) and gunshot wounds (9.6%). CONCLUSION: Half of pediatric trauma deaths occurred within 24 hours. Death from hemorrhage was rare, but all occurred within 6 hours of arrival. This is a critical time for interventions for bleeding control to prevent death from hemorrhage in children. Analysis of these deaths can focus efforts on the urgent need for development of new hemorrhage control adjuncts in children. LEVEL OF EVIDENCE: Epidemiological study, level IV.

Quantifying the need for pediatric REBOA: A gap analysis.

BACKGROUND: Trauma is the leading cause of death in children. Resuscitative endovascular balloon occlusion of the aorta (REBOA) provides temporary hemorrhage control, but its potential benefit has not been assessed in children. We hypothesized that there are pediatric patients who may benefit from REBOA. METHODS: Trauma patients <18 years old at a level 1 pediatric trauma center between 2009 and 2019 were queried for deaths, pre-hospital cardiac arrest, massive transfusion protocol activation, transfusion requirement, or hemorrhage control surgery. These patients defined the cohort of severely injured patients. From this cohort, patients with intraabdominal injuries for which REBOA may provide temporary hemorrhage control were identified, including solid organ injury necessitating intervention, vascular injury, or pelvic hemorrhage. RESULTS: There were 239 severely injured patients out of 6538 pediatric traumas. Of these, 38 had REBOA-amenable injuries (15.9%) with 34.2% mortality, accounting for 10.2% of all pediatric trauma deaths at one center. Eleven patients with REBOA-amenable injuries had TBI (28.9%). Patients with REBOA-amenable injuries represented 0.6% of all pediatric traumas. CONCLUSION: Nearly 20% of severely injured pediatric patients could potentially benefit from REBOA. The overall proportion of pediatric patients with REBOA-amenable injuries is similar to adult studies. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Does the pediatric hemodynamic cliff exist in response to hemorrhagic shock?

BACKGROUND: The paradigm that children maintain normal blood pressure during hemorrhagic shock until 30%-45% hemorrhage is widely accepted. There are minimal data supporting when decompensation occurs and how a child's vasculature compensates up to that point. We aimed to observe the arterial response to hemorrhage and when mean arterial pressure (MAP) decreased from baseline in pediatric swine. METHODS: Piglets were hemorrhaged in 20% increments of their total blood volume to 60%. MAP and angiograms of the thoracic aorta (TA) and abdominal arteries were obtained. Percent change in area of the vessels from baseline was calculated. RESULTS: Piglets (n = 8) had a differential vasoconstriction starting at 20% hemorrhage (celiac artery 36.3% [31.4-44.6] vs TA 16.7% [10.7-19.1] p = 0.0012). At 40% hemorrhage, the differential vasoconstriction favored shunting blood away from the abdominal visceral branches to the TA (celiac artery 54.7% [36.9-60.6] vs TA 29.5% [23.9-36.2] p = 0.0056 superior mesenteric artery 46.7% [43.9-68.6] vs TA 29.5% [23.9-36.2] p = 0.0100). This was exacerbated at 60% hemorrhage. MAP decreased from baseline at 20% hemorrhage (66.4 ±â€¯6.0 mmHg vs 41.4 ±â€¯10.4 mmHg, p < 0.0001), and worsened at 40% and 60% hemorrhage. CONCLUSION: In piglets, a differential vasocontriction shunting blood proximally occurred in response to hemorrhage. This did not maintain normal MAP at 20%, 40% or 60% hemorrhage. LEVEL OF EVIDENCE: Level II.

Resuscitative endovascular balloon occlusion of the aorta in a pediatric swine model: Is 60 minutes too long?

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is recommended in adults with a noncompressible torso hemorrhage with occlusion times of less than 60 minutes. The tolerable duration in children is unknown. We used a pediatric swine controlled hemorrhage model to evaluate the physiologic effects of 30 minutes and 60 minutes of REBOA. METHODS: Pediatric swine weighing 20 kg to 30 kg underwent a splenectomy and a controlled 60% total blood volume hemorrhage over 30 minutes, followed by either zone 1 REBOA for 30 minutes (30R) or 60 minutes (60R). Swine were then resuscitated with shed blood and received critical care for 240 minutes. RESULTS: During critical care, the 30R group's (n = 3) pH, bicarbonate, base excess, and lactate were no different than baseline, while at the end of critical care, these variables continued to differ from baseline in the 60R group (n = 5) and were worsening (7.4 vs. 7.2, p < 0.001, 30.4 mmol/L vs. 18.4 mmol/L, p < 0.0001, 5.6 mmol/L vs. -8.5 mmol/L, p < 0.0001, 2.4 mmol/L vs. 5.7 mmol/L, p < 0.001, respectively). Compared with baseline, end creatinine and creatinine kinase were elevated in 60R swine (1.0 mg/dL vs. 1.7 mg/dL, p < 0.01 and 335.4 U/L vs. 961.0 U/L, p < 0.001, respectively), but not 30R swine (0.9 mg/dL vs. 1.2 mg/dL, p = 0.06 and 423.7 U/L vs. 769.5 U/L, p = 0.15, respectively). There was no difference in survival time between the 30R and 60R pediatric swine, p = 0.99. CONCLUSION: The physiologic effects of 30 minutes of zone 1 REBOA in pediatric swine mostly resolved during the subsequent 4 hours of critical care, whereas the effects of 60 minutes of REBOA persisted and worsened after 4 hours of critical care. Sixty minutes of zone 1 REBOA may create an irreversible physiologic insult in a pediatric population.

The Use of Chest Computed Tomographic Angiography in Blunt Trauma Pediatric Population.

INTRODUCTION: Blunt chest trauma in children is common. Although rare, associated major thoracic vascular injuries (TVIs) are lethal potential sequelae of these mechanisms. The preferred study for definitive diagnosis of TVI in stable patients is computed tomographic angiography imaging of the chest. This imaging modality is, however, associated with high doses of ionizing radiation that represent significant carcinogenic risk for pediatric patients. The aim of the present investigation was to define the incidence of TVI among blunt pediatric trauma patients in an effort to better elucidate the usefulness of computed tomographic angiography use in this population. METHODS: A retrospective cohort study was conducted including all blunt pediatric (age < 14 y) trauma victims registered in Israeli National Trauma Registry maintained by Gertner Institute for Epidemiology and Health Policy Research between the years 1997 and 2015. Data collected included age, sex, mechanism of injury, Glasgow Coma Scale, Injury Severity Score, and incidence of chest named vessel injuries. Statistical analysis was performed using SAS statistical software version 9.2 (SAS Institute Inc, Cary, NC). RESULTS: Among 433,325 blunt trauma victims, 119,821patients were younger than 14 years. Twelve (0.0001%, 12/119821) of these children were diagnosed with TVI. The most common mechanism in this group was pedestrian hit by a car. Mortality was 41.7% (5/12). CONCLUSIONS: Thoracic vascular injury is exceptionally rare among pediatric blunt trauma victims but does contribute to the high morbidity and mortality seen with blunt chest trauma. Computed tomographic angiography, with its associated radiation exposure risk, should not be used as a standard tool after trauma in injured children. Clinical protocols are needed in this population to minimize radiation risk while allowing prompt identification of life-threatening injuries.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) in a pediatric swine liver injury model: A pilot study.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has not been studied in children. We hypothesized that REBOA was feasible and would improve hemorrhage control and survival time, compared to no aortic occlusion, in a pediatric swine liver injury model. METHODS: Pediatric swine were randomized to Zone 1 REBOA or no intervention (control). Piglets underwent a partial liver amputation and free hemorrhage followed by either REBOA or no intervention for 30 min, then a damage control laparotomy and critical care for 4 h. RESULTS: Compared to control piglets (n = 5), REBOA piglets (n = 6) had less blood loss (34.0 ±â€¯1.6 vs 61.3 ±â€¯2.5 mL/kg, p < 0.01), higher end hematocrit (28.1 ±â€¯2.1 vs 17.1 ±â€¯4.1%, p = 0.03), higher end creatinine (1.4 ±â€¯0.1 vs 1.2 ±â€¯0.1 mg/dL, p = 0.05), higher end ALT and AST (56 ±â€¯4 vs 32 ±â€¯6 U/L, p = 0.01 and 155 ±â€¯26 vs 69 ±â€¯25 U/L, p = 0.05) and required more norepinephrine during critical care (1.4 ±â€¯0.3 vs 0.3 ±â€¯0.3 mg/kg, p = 0.04). All REBOA piglets survived, whereas 2 control piglets died, p = 0.10. CONCLUSION: In pediatric swine, 30 min of REBOA is feasible, decreases blood loss after liver injury and may improve survival. LEVEL OF EVIDENCE: Level 1.

Development of transfusion guidelines for injured children using a Modified Delphi Consensus Process.

BACKGROUND: There is wide variability of transfusion practices for children with hemorrhagic injuries across trauma centers. We are planning a multicenter, randomized clinical trial evaluating tranexamic acid in children with hemorrhage. Standardization of transfusion practices across sites is important to minimize confounding. Therefore, we sought to generate consensus-based transfusion guidelines for the trial. METHODS: We used a modified Delphi process utilizing a multi-site, multi-disciplinary panel of experts to develop our transfusion guidelines. A survey of 23 clinical categories on various aspects of transfusion practices was developed and distributed via SurveyMonkey®. Statements were graded on a 5-point Likert scale ("Strongly agree" to "This intervention may be harmful"). Statements were accepted if ≥ 80% of the panelists rated the statement as "Strongly agree" or "Agree". After each round, the responses were calculated and the results included on subsequent rounds. RESULTS: 35 panelists from four pediatric trauma centers participated in the study, including 11 (31%) pediatric EM physicians, 8 (23%) pediatric trauma surgeons, 5 (14%) transfusionists, 5 (14%) pediatric anesthesiologists, and 6 (17%) pediatric critical care physicians (range of 8 to 10 from each clinical site). Four survey iterations were performed. In total 176 statements were rated and 39 were accepted by criteria across all 23 categories. An rational algorithm for transfusion in trauma was then developed. CONCLUSIONS: We successfully developed transfusion guidelines for various aspects of the management of children with hemorrhagic injuries using a modified Delphi process with broad interdisciplinary participation. We anticipate implementation of these guidelines will help minimize heterogeneity of transfusion practices across clinical sites for the upcoming clinical trial evaluating tranexamic acid in children with hemorrhage.

Surgical management of pediatric rectal prolapse: A survey of the American Pediatric Surgical Association (APSA).

INTRODUCTION: Many management options exist for the treatment of refractory rectal prolapse (RP) in children. Our goal was to characterize current practice patterns among active members of APSA. METHODS: A 23-item questionnaire assessed the management of full-thickness RP for healthy children who have failed medical management. The survey was approved by our IRB and by the APSA Outcomes committee. RESULTS: 236 surgeons participated. The respondents were geographically dispersed (44 states, 5 provinces). 32% of respondents had twenty or more years of clinical experience. 71% evaluated 1-5 RP patients in the last 2 years, while 5% evaluated >10. 71% performed 0-1 procedure (operation or local therapy [LT]) for RP over 2 years. 59% would treat a 2-year-old patient differently than a 6-year-old with the same presentation, and were more likely to offer up-front surgery to a 6-year-old (26% vs 15%, p = 0.04), less likely to continue medical management indefinitely (2% vs 7%, p=0.01), and more likely to perform resection with rectopexy (30% vs. 15%, p=0.01). 71% perform LT as an initial intervention: injection sclerotherapy (59%), anal encirclement (8%), and sclerotherapy + anal encirclement (5%). 70% consider LT a failure after 1-3 attempts. If LT fails, surgical management consists of transabdominal rectopexy (46%), perineal proctectomy or proctosigmoidectomy (22%), transabdominal sigmoidectomy + rectopexy (22%), and posterior sagittal rectopexy (9%). CONCLUSIONS: There is wide variability in the surgical management of pediatric rectal prolapse. This suggests a need for development of processes to identify best practices and optimize outcomes for this condition.

Age-related mortality in abusive head trauma.

BACKGROUND: Abusive head trauma (AHT) peaks during early infancy and decreases in toddler years. Infants and toddlers experience different injuries, possibly impacting the risk of mortality. We aimed to evaluate the association of age with mortality. METHODS: We conducted a retrospective study of AHT hospitalizations in 2000, 2003, 2006, 2009, and 2012 from the Kid's Inpatient Claims Database. An accidental head trauma cohort was included to hypothesize that the association between age and mortality is unique to abuse. A nested multivariable logistic regression was used to perform the analysis. RESULTS: Children aged 2 years to 4 years experienced higher mortality than those younger than 2 years (22% vs. 10%, p < 0.0001; adjusted odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.2). The presence of subarachnoid hemorrhage (OR, 1.9; 95% CI, 1.3-2.9), cerebral edema (OR, 4.0; 95% CI, 2.9-5.4), and retinal hemorrhage (OR, 1.9; 95% CI, 1.5-2.5) were associated with an increase risk in mortality. Children younger than 2 years experienced more fractures and hemorrhage (subdural, subarachnoid, retinal) while children aged 2 years to 4 years encountered more internal injuries and cerebral edema.In children with accidental head trauma, those aged 2 years to 4 years have a lower mortality compared with those younger than 2 years (OR, 0.4; 95% CI, 0.3-0.6). Among children younger than 2 years, AHT and accidental trauma had comparable risk of mortality (OR, 0.9; 95% CI, 0.6-1.3). However, among those aged 22 years to 4 years, AHT had a higher risk of mortality than accidental trauma (OR, 3.3; 95% CI, 2.1-5.1). CONCLUSION: There is a considerable risk of mortality associated with age at diagnosis in children with AHT.Children younger than 2 years and those aged 2 years to 4 years present with different types of injuries. The high risk of mortality in the children aged 2 years to 4 years is unique to AHT. Efforts should be made to increase awareness about the risk of mortality and identify factors that can aide in a timely accurate diagnosis. LEVEL OF EVIDENCE: Prognostic and epidemiological study, level III.

Epidemiology of Hirschsprung disease in California from 1995 to 2013.

PURPOSE: This study seeks to update current epidemiology of Hirschsprung disease (HD) in California. METHODS: Using data from the California Office of Statewide Health Planning and Development Linked Birth (1995-2012) and Patient Discharge Databases (1995-2013), patients from either dataset with an ICD-9 diagnosis code of HD (751.3) or procedure code of Soave (48.41), Duhamel (48.65), or Swenson/other pull-through (48.49) were included. Patients > age 18 during their first admission were excluded. RESULTS: Of 9.3 million births, 2,464 patients were identified. Incidence was 2.2 cases/10,000 live births, with rates peaking at 2.9/10,000 births in 2002. Incidence was highest among African American (4.1/10,000) and Asian/Pacific Islander (2.5/10,000) births. Most were male (n = 1652, 67.1%). Sixty patients (2.4%) had Down syndrome. The median gestational age at birth was 38 weeks 6 days (interquartile range [IQR] 37 weeks 1 day-40 weeks 1 day). Mortality during the first year of life was 1.7%. Median age at death was 14.5 days (IQR 0-113 days). CONCLUSION: This is one of the largest population-based studies of HD. In California, the incidence of HD is stable, risk is highest among African American children, and the mortality rate is < 2%.

Epidemiology of gastroschisis: A population-based study in California from 1995 to 2012.

BACKGROUND: Although the incidence of gastroschisis is increasing, risk factors are not clearly identified. METHODS: Using the Linked Birth Database from the California Office of Statewide Health Planning and Development from 1995 to 2012, patients with gastroschisis were identified by ICD-9 diagnosis/procedure code or birth certificate designation. Logistic regressions examined demographics, birth factors, and maternal exposures on risk of gastroschisis. RESULTS: The prevalence of gastroschisis was 2.7 cases per 10,000 live births. Patients with gastroschisis had no difference in fetal exposure to alcohol (p = 0.609), narcotics (p = 0.072), hallucinogenics (p = 0.239), or cocaine (p = 0.777), but had higher exposure to unspecified/other noxious substances (OR 3.27, p = 0.040; OR 2.02, p = 0.002). Gastroschisis was associated with low/very low birthweight (OR 5.08-16.21, p < 0.001) and preterm birth (OR 3.26-10.0, p < 0.001). Multivariable analysis showed lower risk in black (OR 0.44, p < 0.001), Asian/Pacific Islander (OR 0.76, p = 0.003), and Hispanic patients (OR 0.72, p < 0.001) compared to white patients. Risk was higher in rural areas (OR 1.24-1.76, p = 0.001). Compared to women age < 20, risk decreased with advancing maternal age (OR 0.49-OR 0.03, p < 0.001). Patients with gastroschisis had increased total charges ($336,270 vs. $9012, p < 0.001) and length of stay (38.1 vs. 2.9 days, p < 0.001). Mortality was 4.6%. CONCLUSIONS: This is the largest population-based study summarizing current epidemiology of gastroschisis in California. TYPE OF STUDY: Retrospective comparative cohort study. LEVEL OF EVIDENCE: III.

A Nationwide Assessment of Pediatric Surgical Capacity in Mongolia.

BACKGROUND: Mongolia is a country characterized by its vast distances and extreme climate. An underdeveloped medical transport infrastructure makes patient transfer from outlying regions dangerous. Providing pediatric surgical care locally is crucial to improve the lives of children in the countryside. This is the first structured assessment of nationwide pediatric surgical capacity. METHODS: Operation rates were calculated using data from the Mongolian Center for Health Development and population data from the Mongolian Statistical Information Service. The Pediatric Personnel, Infrastructure, Procedures, Equipment, and Supplies (PediPIPES) survey tool was used to collect data at all survey sites. Descriptive data analyses were completed using Excel. Studies of association were completed using Stata. All reported percentages are of the hospitals outside of the capital (n = 21). RESULTS: All provincial hospitals have general surgeons; seven (33.3%) of them have pediatric surgeon(s). One facility has no anesthesiologist. All facilities perform basic procedures and provide anesthesia. Four (19%) can treat common congenital anomalies. All facilities have basic operating room equipment. Nine hospitals do not have pulse oximetry available. Twelve hospitals do not have pediatric surgical instruments always available. Pediatric supplies are lacking. CONCLUSIONS: Provincial hospitals in Mongolia can perform basic procedures. However, essential pediatric supplies are lacking. Consequently, certain life-saving procedures are not available to children outside of the capital. Only a few improvements would be amendable to low-cost process improvement adjustment, and the majority of needs require resource additions. Procedure, equipment, and supply availability should be further explored to develop a comprehensive nationwide pediatric surgical program.

Subcutaneous local anesthetic infusion could eliminate use of epidural analgesia after the Nuss procedure.

AIM: To compare outcomes of continuous subcutaneous infusion of local anesthetic and epidural analgesia following the Nuss procedure. PATIENTS & METHODS: A retrospective chart review compared patients managed with subcutaneous local anesthetic infusion (n = 12) versus thoracic epidural (n = 19) following the Nuss procedure from March 2013 to June 2015. RESULTS: There was no difference in hospital length of stay or days on intravenous narcotics. Epidural catheter placement prolonged operating room time (146.58 ± 28.30 vs 121.42 ± 21.98 min, p = 0.01). Average pain scores were slightly higher in the subcutaneous infusion group (3.72 ± 1.62 vs 2.35 ± 0.95, p = 0.02), but of negligible clinical significance. CONCLUSION: Continuous subcutaneous infusion of local anesthetic could eliminate the need for thoracic epidural for pain management after the Nuss procedure.

Strength and histology of a nanofiber scaffold in rats.

BACKGROUND: Full-thickness soft tissue defects from congenital absence or traumatic loss are difficult to surgically manage. Healing requires cell migration, organization of an extracellular matrix, inflammation, and wound coverage. PLCL (70:30 lactide:caprolactone, Purac), poly(propylene glycol) nanofibrous scaffolds enhance cell infiltration in vitro. This study compares strength and tissue ingrowth of aligned and unaligned nanofibrous scaffolds to absorbable and permanent meshes. We hypothesize that PLCL nanofibrous grafts will provide strength necessary for physiological function while serving as a scaffold to guide native tissue regeneration in vivo. MATERIALS AND METHODS: Abdominal wall defects were created in 126 rats followed by underlay implantation of Vicryl, Gore-Tex, aligned, or unaligned PLCL Nanofiber mesh. Specimens were harvested at 2, 6, and 12 wk for strength testing and 2, 12, and 24 wk for histopathologic evaluation. Specimens were graded for cellular infiltration, multinucleated giant cells (MNG), vascularity, and tissue organization. Mean scores were compared and analyzed with non-parametric testing. RESULTS: The PLCL grafts maintained structural integrity until at least 12 wk and exhibited substantial tissue replacement at 24 wk. At 12 wk, only the aligned PLCL had persistent cellular infiltration of the graft, whereas both aligned and unaligned PLCL grafts showed the presence of MNG. The presence of MNGs decreased in the aligned PLCL graft by 24 wk. CONCLUSIONS: The aligned PLCL nanofiber mesh offers early strength comparable to Gore-Tex but breaks down and is replaced with cellular ingrowth creating a favorable option in management of complex surgical wounds or native soft tissue defects.

Caring for the injured child in settings of limited resource.

Children represent the most vulnerable members of our global society, a truth that is magnified when they are physically wounded. In much of the developed world, society has responded by offering protection in the form of law, injury prevention guidelines, and effective trauma systems to provide care for the injured child. Much of our world, though, remains afflicted by poverty and a lack of protective measures. As the globe becomes smaller by way of ease of travel and technology, surgeons are increasingly able to meet these children where they live and in doing so offer their hands and voices to care and protect these young ones. This article is intended as an overview of current issues in pediatric trauma care in the developing world as well as to offer some tips for the volunteer surgeon who may be involved in the care of the injured child in a setting of limited resource availability.

Intradiaphragmatic pulmonary sequestration: advantages of the thoracoscopic approach.

Pulmonary sequestrations are accessory foregut lesions that are most commonly located within the thorax and occasionally in the abdominal cavity. Sequestrations arising within the diaphragm are exceedingly rare. We describe 2 patients found to have left peridiaphragmatic lesions on prenatal ultrasound and postnatal computed tomography. In the first patient, an initial laparoscopic approach was abandoned in favor of a thoracoscopic approach after no intraabdominal mass was found. The second patient had an uncomplicated thoracoscopic resection of a similar lesion. To our knowledge, these represent the first intradiaphragmatic pulmonary sequestrations to be resected via a minimally invasive approach. The rarity of these lesions makes definitive diagnosis without operative intervention challenging. Thoracoscopy appears to be a reasonable approach for resection of such intradiaphragmatic lesions.

Noningested intraperitoneal foreign body causing chronic abdominal pain: a role for laparoscopy in the diagnosis.

In this article, we present an unusual case of a young boy who presented with abdominal pain and was found to have a sewing needle that had migrated through the abdominal wall into the peritoneal space. After imaging and endoscopy, the needle was extracted laparoscopically without any evidence of intra-abdominal organ injury and with a good long-term outcome for the child. There are no other such reported cases in the literature. This case highlights the subtleties in management of intra-abdominal foreign bodies in children including rare causes such noningested foreign bodies.

Ewing sarcoma/primitive neuroectodermal tumor arising from the adrenal gland in an adolescent.

We review the case of an adolescent who presented with flank pain, fatigue and a discrete nonfunctioning adrenal lesion which was found to be an adrenal Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET). The patient was treated with a minimally invasive adrenalectomy as a component of multimodal therapy, including seven courses of chemotherapy and whole abdominal radiation. She is currently disease free 14 months after the operation and 3 months off therapy.
