Outcomes following adoption of a standardized protocol for abscess drain management in pediatric appendicitis.

BACKGROUND/PURPOSE: Though evidence-based clinical pathways for the diagnosis and treatment of pediatric appendicitis have been established, protocols guiding management of percutaneous abscess drains are lacking. We hypothesized a drain management protocol utilizing drain output and clinical factors instead of fluoroscopic drain studies would reduce interventional radiologic procedures without adversely impacting clinical outcomes. METHODS: A standardized protocol was uniformly adopted at a tertiary-care children's hospital in April 2016. A retrospective chart review included all cases of appendicitis requiring abscess drainage by interventional radiology three years pre- and postprotocol implementation. RESULTS: Fifty-eight patients (preprotocol = 39, postprotocol = 19) underwent percutaneous abscess drainage, of whom 52 (preprotocol = 34, postprotocol = 18) required a drain. Baseline demographics and clinical presentation were similar across groups. Following protocol implementation, total number of IR procedures decreased from 2.4 to 1.3 per patient (p = 0.004). There was no significant difference in the number of postprocedure diagnostic imaging studies, readmissions, or inpatient days, and there was a trend towards a decrease in number of drain days (10.7 to 5.7, p = 0.067). CONCLUSION: A standardized protocol for management of abscess drains for complicated appendicitis reduced the number of IR procedures without a negative impact on clinical outcomes or increase in alternative imaging studies. This approach may decrease radiation exposure, anesthetic administration, and resource utilization. TYPE OF STUDY: Treatment study (retrospective comparative study). LEVEL OF EVIDENCE: Level III.

Establishing a National Rate of Rectal Biopsy Positivity in the Diagnosis of Hirschsprung Disease.

OBJECTIVES: Although rectal biopsy has long been established as the criterion standard for the diagnosis of Hirschsprung disease, little to no information exists regarding nationwide rates of rectal biopsy positivity or interinstitutional variability. We sought to determine the national rate of rectal biopsy positivity and factors contributing to institutional variability. METHODS: A retrospective review of the Children's Hospital Association's (CHA) Pediatric Health Information System from 2009 to 2018 identified infants <100 days old with ICD-9/ICD-10 procedural codes for rectal biopsy in addition to codes for pull-through procedures within 500 days of life as a proxy for positive biopsy. A subgroup analysis of only patients biopsied at institutions with positive biopsy rates 1 standard deviation above or below the mean positive biopsy rate (deemed high and low outliers) was performed to better delineate these populations. RESULTS: A total of 7225 children underwent rectal biopsies between 2009 and 2018 at 52 Children's Hospital Association Hospitals. Mean positive biopsy rate for individual institutions was 21.5% (standard deviation ±â€Š6.4%). Linear regression to predict the effect of hospital surgical volume on positive biopsy rate demonstrated no volume outcome relationship (R2 = 0.049). Patients at high outlier hospitals for biopsy positivity were found to travel significantly further to the hospital (232.5 vs 123.1 miles, P < 0.0001) when compared to patients presenting at low outlier hospitals. CONCLUSIONS: There appears to be little interinstitutional variability in the rate of surgery following rectal biopsy for presumed Hirschsprung and no significant relationship to surgical volume. About 1 in every 4 infants undergoing biopsy proceeds to surgery.

History of appendectomy? An atypical case of recurrent abdominal pain.

Acute appendicitis is a common condition emergency physician encounter during pediatric emergency visits. With a reported incidence of 1 in 50,000 appendectomies, stump appendicitis, an acute inflammation of the residual appendicular tissue, is a rare post-operative complication. The diagnosis of stump appendicitis is time-critical to prevent associated morbidities of abscess formation, perforation and sepsis. Another atypical presentation of appendicitis includes recurrent appendicitis, which is recognized as one or more previous episodes of similar clinical presentation as acute appendicitis, but symptoms subside within 24 to 48 hours. Intervals between attacks may vary from weeks to years during which the patient may be asymptomatic. Although recurrent appendicitis is rare, emergency physicians should be aware of this possibility and to not assume that previous appendectomy precludes recurrent appendicitis. This case highlights the importance of considering such unusual condition in a patient presenting with recurrent right-sided abdominal pain.

An Evidence-Based Guideline Supporting Restricted Opioid Prescription after Pediatric Appendectomy.

BACKGROUND/PURPOSE: Surgeon overprescription of opioids is a modifiable contributor to the opioid epidemic. No clear guidelines exist for prescribing opioids to younger patients after surgery. We sought to determine postoperative opioid needs in pediatric/young adult patients after laparoscopic appendectomy. METHODS: Patients 5-20 years old who underwent laparoscopic appendectomy were included for study. All consented patients underwent chart review and were additionally called for an attempted interview. Caregivers were queried on analgesic use and adequacy of pain relief. The main outcome measures were: quantity of opioid used, desire for an opioid, presence of pain ≥4/10, and need for follow-up/call owing to pain. All opioids were converted into morphine milligram equivalents (MME). RESULTS: Seventy-three patients qualified for the study, 49 of whom completed a postoperative telephone interview. Of the interviewees, 83% did not use or desire an opioid and reported pain <4/10 after discharge. Five patients used an opioid upon discharge, and the average MME consumed was 23 (equivalent to 3 pills of 5 mg oxycodone). No zero-opioid patients had unanticipated follow-up for pain concerns. CONCLUSIONS: After hospital discharge following laparoscopic appendectomy, most patients have adequate analgesia without opioids. Opioid prescriptions should be offered sparingly and for no more than 25 MME. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Prognosis study.

Hirschsprung Disease: The Rise of Structured Transition and Long-term Care.

Hirschsprung disease, like most surgically correctable congenital anomalies, is now survivable well into adulthood. Patients are, therefore, presenting later in life with problems that were previously infrequently encountered by colorectal surgeons or gastroenterologists. The goals of our review are to describe the current state of care transition for this patient population, identify the specific needs for these patients, and propose guidelines which could inform a future model of transition from the pediatric to adult setting. This is a review of the current state of care transition and long-term outcomes for patients with Hirschsprung disease. Although these patients report a generally good quality of life, the majority suffer from some degree of lifelong gastrointestinal complication, regardless of the type of operative repair. A more formalized transition of care will provide a guide for pediatric surgeons and patients, alleviate colorectal surgeon and gastroenterologist concerns, and provide better long-term care for these patients.

Opioid Prescribing Habits of General Versus Pediatric Surgeons After Uncomplicated Laparoscopic Appendectomy.

BACKGROUND: Adolescents who use prescription opioids have an increased risk for future drug abuse and overdose, making them a high-risk population. Appendectomy is one of the most common surgical procedures in this age group, often requires opioid analgesia, and is performed by both pediatric and general surgeons. Prescription patterns comparing these two provider groups have not yet been evaluated; we hypothesize that general surgery providers prescribe more opioids for adolescent and young adult patients than do pediatric surgery providers. METHODS: A retrospective chart review was conducted across a single health system consisting of four hospitals. All uncomplicated laparoscopic appendectomies performed between January 1, 2016 and August 14, 2017 on patients aged 7-20 were included for analysis. Any case coded for multiple procedures, identified as converted to open, or had a length of stay >48 h were excluded. The primary outcome measure was amount of opioid prescribed postoperatively. To standardize different formulations and types of analgesia prescribed, prescriptions were converted into oral morphine equivalents (OMEs). For reference, one 5 mg pill of oxycodone equals 7.5 OME. Linear regression was performed controlling for patient weight, gender, race, insurance status, provider type (pediatric versus general surgery), and provider level (resident, advanced practice provider, and attending). RESULTS: A total of 336 pediatric laparoscopic appendectomies were analyzed, 148 by general surgeons and 188 by pediatric surgeons. Pediatric surgeons prescribed less opioid than general surgeons overall (59 OME versus 90 OME, P < 0.0001). For patients aged <13 y, there was no significant difference between pediatric (26 OME) and general (37 OME, P = 0.8921) surgeons. However, for the age group 13-20 y, pediatric surgeons prescribed 25% less opioid than general surgeons (90 OME versus 112.5 OME, P < 0.0001). Regression analysis demonstrated that being cared for by a general surgery service (+24.1 OME [95% confidence interval 9.8-38.3]) was associated with high prescribing, whereas having Medicaid was associated with lower prescription amounts (-16.4 OME [95% confidence interval -32.5 to -0.3]). CONCLUSIONS: After an uncomplicated laparoscopic appendectomy, general surgeons prescribe significantly more opioid to adolescent patients than do pediatric surgeons, even when controlling for age and weight. One substantial and modifiable contributor of the opioid epidemic is the amount of opioid prescribed. The variability of prescribing habits to adolescents and young adults demonstrates a clear need for increased education and guidelines on this topic, especially for surgeons who do not frequently treat the younger and more vulnerable population.

Routine postnatal chest x-ray and intensive care admission are unnecessary for a majority of infants with congenital lung malformations.

BACKGROUND: Postnatal evaluation of prenatally identified congenital lung malformations (CLMs) often includes a chest x-ray (CXR) and neonatal intensive care unit (NICU) admission for observation. With current efforts aimed at prioritizing value and resource utilization, we sought to assess the utility of this practice in infants with known CLMs. We hypothesized that CXR and NICU admission are overused and could be deferred in the majority of cases. METHODS: Clinical and radiographic data for infants with CLM from 2007 to 2016 were reviewed with IRB approval. Regression models were developed for respiratory support (RS), symptoms within 30 days of discharge (Sx30), and abnormal CXR. Predictors included initial symptoms (IS), birth weight (BW), gestational age (GA), cyst-volume-ratio (CVR) and abnormal CXR. Odds ratios (ORs) and ROC curves were generated for significant predictors (p < 0.05). RESULTS: Fifty-eight infants were identified. Eight were excluded because birth or surgery occurred outside of our institution. Another four were excluded for requiring immediate surgery, leaving forty-six for full analysis. All infants underwent initial CXR and NICU admission, and 22 (47.8%) had an abnormal CXR. Higher CVR (OR = 6.69, p = 0.024) and lower BW (OR = 0.27, p = 0.028) both increased the odds of an abnormal CXR. Applying optimal ROC cutoffs for CVR and BW would have safely eliminated 21 of 46 CXRs, increasing CXR sensitivity from 48% to 68%. For RS and Sx30, no variable, including abnormal CXR, significantly predicted outcomes. Twenty-seven infants (59%) had a NICU stay of <24 h and only three patients (6.8%) developed Sx30. CONCLUSIONS: Both CXR and NICU admission appear to be overused in infants with CLM. CXR result did not predict need for respiratory support or symptoms following discharge, and thus may not aid in the initial evaluation or in the prediction of future care needs. Using CVR and birth weight can guide CXR use and optimize its sensitivity. Need for NICU admission could not be predicted, but a majority of infants spent <24 h in the NICU without intervention, suggesting that NICU admission was likely not needed for all infants in this setting. LEVEL OF EVIDENCE: Study of diagnostic test, Level II evidence.

Surgical tray optimization as a simple means to decrease perioperative costs.

BACKGROUND: Health care spending in the US remains excessively high. Aside from complicated, large-scale efforts at health care cost reduction, there are still relatively simple ways in which individual hospitals can cut unnecessary costs from everyday operations. Inspired by recent publications, our group sought to decrease the costs associated with surgical instrument processing at a large, multihospital academic center. METHODS: This was a single-site observational study conducted at a large academic medical center. At the study start, all attending surgeons within the section of pediatric surgery agreed to standardize the pediatric surgery trays and to eliminate instruments that were deemed unnecessary from each tray. A multidisciplinary start-up meeting was held, and this meeting included stakeholders from central sterile processing, operating room nursing, scrub technicians, and materials management along with all five pediatric surgeons. Each tray was addressed individually. Instruments were eliminated from trays only if there was unanimous agreement among all the surgeons in the group. If no instruments in a given surgical tray were deemed necessary, the entire tray was eliminated from sterile processing rotation. Feedback questionnaires were drafted by the multidisciplinary team that participated in the start-up meeting. Surgeons were allowed to request for certain instruments to be placed back into the trays at any time, and the questionnaires also allowed for free-hand comments. Surgical kit preparation time was obtained from the institutional barcode scanning system. The cost per second of sterile processing labor was calculated using regional median salary for sterile processing technicians in the state of Connecticut. Using the pediatric surgery section as the model unit, this method was then applied to pediatric urology, neurosurgery, spine surgery, and orthopedics. RESULTS: The pediatric surgery section eliminated an average of 59.5% of instruments per tray, resulting in an overall reduction of 1826 (39.5%) instruments from rotation, 45,856 fewer instruments processed per year, and nine trays eliminated completely from regular rotation. Processing time for six commonly used trays was reduced by an average of 28.7%. The urology section eliminated 18 trays from regular rotation and 179 (10.1%) instruments in total. Pediatric orthopedics, neurosurgery, and spine sections eliminated 708 (17.1%), 560 (92.7%), and 31 (32.2%) instruments, respectively, resulting in approximately 18,804 fewer instruments processed per year. Among all five surgical sections, annual instrument cost avoidance after tray optimization was estimated at $53,193 to $531,929 using average instrument life spans ranging from 1-10 y. Negative feedback and requests for instrument replacement were both minimal on feedback questionnaires. CONCLUSIONS: Surgical tray optimization represents a relatively simple microsystem improvement that could result in significant hospital cost reduction. Although difficult to quantify, other gains from surgical kit optimization include decreased weight per tray, decreased materials cost, and decreased labor required to count, decontaminate, and pack surgical trays.

An investment in knowledge: Research in global pediatric surgery for the 21st century.

The body of literature addressing surgical and anesthesia care for children in low- and middle-income countries (LMICs) is small. This lack of research hinders full understanding of the nature of many surgical conditions in LMICs and compromises potential efforts to alleviate the significant health, welfare and economic burdens surgical conditions impose on children, families and countries. This article will evaluate the need for improved global pediatric surgery research by (1) presenting the current state of surgical research for children in LMICs and (2) discussing methods and opportunities for improvement within the political context of current global health priorities.

Pediatric thymomas: report of two cases and comprehensive review of the literature.

PURPOSE: Thymomas are rare pediatric malignancies with indolent behavior. There are fewer than 50 reported cases and no comprehensive review. We sought to evaluate our recent experience with pediatric thymomas, and comprehensively review the extant literature. METHODS: A systematic search of the PubMed database was performed using keywords: "thymoma", "pediatric", "juvenile", "childhood", and "child". Additional studies were identified by a manual search of the reference list. RESULTS: We report two patients with thymomas. We identified 22 case reports or series that described 48 patients; 62 % were male, 15 % presented with myasthenia gravis. Fifty percent were Masaoka Stage I, 15 % were Stage II, 13 % were Stage III, and 23 % were Stage IV. Four patients with early stage (I or II) disease were treated with adjuvant therapies in addition to surgical excision, while five patients with late stage (III or IV) disease treated with surgical excision alone. Of studies reporting at least 2-year follow-up, survival was 71 %. CONCLUSION: Pediatric thymomas are rare tumors with a slight male predominance. Wide variations were observed in the treatment of thymomas across all stages. Our review indicates a need for large database and multi-institutional studies to clearly elucidate clinical course, prognostic factors and outcome.

A warning: don't be stumped by stump appendicitis.

When an emergency medicine physician evaluates a child with abdominal pain and a history of appendectomy, appendicitis is often excluded from the differential. We present a case of a 16-year-old boy who developed stump appendicitis 3 years after laparoscopic appendectomy. Knowledge of this rare phenomenon in children can lead to timely diagnosis and avoid the significant additional morbidity associated with perforation of the stump.

Splenic conservation: variation between pediatric and adult trauma centers.

OBJECTIVES: Nonoperative management of hemodynamically stable children and adolescents with splenic injury regardless of grade has become standard; however, numerous studies have shown a wide variation in management. We compared the treatment and outcomes of adolescent splenic injuries in our region, which includes a pediatric level I trauma center (PTC) and an adult level I trauma center (ATC). METHODS: A retrospective review of the trauma registry was performed on patients 14 to 17 y old with blunt splenic injury admitted to either the local PTC or ATC from January 1999 through December 2010. Demographics, interventions, and hospital course were recorded and compared using Fisher exact, Student t-test, and multivariate analysis. RESULTS: Eighty-six adolescent patients presenting to the PTC and 65 patients presenting to the ATC met the criteria over the 12-y period. Although the ATC received more significantly injured and slightly older patients, logistic multivariate analysis demonstrated that the location of presentation was the only independent factor associated with splenectomy (P = 0.0015). A higher injury severity score was associated with a longer length of stay (LOS), but the nonoperative approach was not associated with a longer LOS (P = 0.96). CONCLUSIONS: Our study demonstrates that the location of presentation was independently associated with splenectomy while controlling for a higher injury severity score at the ATC. With the higher percentage of nonoperative management, treatment at the PTC was not associated with an increased LOS (total or intensive care unit).

Are facilities following best practices of pediatric abdominal CT scans?

BACKGROUND: Established guidelines for pediatric abdominal CT scans include reduced radiation dosage to minimize cancer risk and the use of intravenous (IV) contrast to obtain the highest-quality diagnostic images. We wish to determine if these practices are being used at nonpediatric facilities that transfer children to a pediatric facility. METHODS: Children transferred to a tertiary pediatric facility over a 16-mo period with abdominal CT scans performed for evaluation of possible appendicitis were retrospectively reviewed for demographics, diagnosis, radiation dosage, CT contrast use, and scan quality. If CT scans were repeated, the radiation dosage between facilities was compared using Student t-test. RESULTS: Ninety-one consecutive children transferred from 29 different facilities had retrievable CT scan images and clinical information. Half of CT scans from transferring institutions used IV contrast. Due to poor quality or inconclusive CT scans, 19 patients required a change in management. Children received significantly less radiation at our institution compared to the referring adult facility for the same body area scanned on the same child (9.7 mSv versus 19.9 mSv, P = 0.0079). CONCLUSION: Pediatric facilities may be using less radiation per CT scan due to a heightened awareness of radiation risks and specific pediatric CT scanning protocols. The benefits of IV contrast for the diagnostic yield of pediatric CT scans should be considered to obtain the best possible image and to prevent additional imaging. Every facility performing pediatric CT scans should minimize radiation exposure, and pediatric facilities should provide feedback and education to other facilities scanning children.

Computed tomography scanning in pediatric trauma: opportunities for performance improvement and radiation safety.

BACKGROUND: Recently, pediatric CT scanning protocols have reduced radiation exposure in children. Because evaluation with CT scan after trauma contributes to significant radiation exposure, we reviewed the CT scans in children at both initial presentation at a non-pediatric facility and subsequent transfer to a level I pediatric trauma center (PTC) to determine the number of scans, body area scanned, radiation dosage, and proportion of scans at each facility. METHODS: The trauma database was retrospectively reviewed for children aged 0 to 17 y initially evaluated for trauma at another facility and then transferred to our PTC for pediatric specialty care between January 2000 and December 2010. RESULTS: A total of 1562 patients with 1335 CT scans were reviewed over an 11-y period. The majority of CT scans occur at the referring facility compared to the PTC in a ratio of 7:3. CT of the head was the most frequent scan obtained (52%), and 17.9% of CT scans were repeated at the PTC. Less than 1% of CT scans performed at the non-pediatric centers contained radiation dosage information, precluding analysis of radiation exposure. CONCLUSIONS: The majority of CT scans for trauma occur at non-pediatric facilities, which demonstrates the need for referring facilities to perform optimal CT scans with the least amount of radiation exposure to the child. We believe this provides an opportunity for PTC performance improvement by facilitating the transfer of images and educating referring facilities about indications for CT scans, dosage amounts, and radiation reduction protocols.

Myositis ossificans requires multiple diagnostic modalities.

Myositis ossificans is a type of bone-forming lesion that arises in soft tissue and mimics malignancy. We present a case of myositis ossificans in a 16-year-old girl with anxiety disorder, Asperger syndrome, and no known history of trauma. A variety of diagnostic tools including magnetic resonance, ultrasound, and biopsy are used to make the diagnosis. The histologic and radiographic findings used to distinguish this disorder from malignant conditions are discussed.

Life-threatening hemorrhage from a congenital hemangioma caused by birth trauma.

Pediatric surgeons frequently diagnose and treat vascular malformations. We present the case of a boy born with a large congenital hemangioma of the flank that ruptured during birth, resulting in life-threatening hemorrhage, requiring emergent excision. Prenatal diagnosis may help to identify such lesions, and pediatric surgeons must be ready to treat emergent complications of vascular malformations.

Magnetic resonance as an aid in the diagnosis of a transverse vaginal septum.

Transverse vaginal septum is a rare, often overlooked congenital abnormality that is typically not diagnosed until adolescence. We present the case of a transverse vaginal septum and partial bicornuate uterus in a 16-year-old adolescent girl with developmental delay and cerebral palsy. Magnetic resonance is an excellent diagnostic tool to delineate the specific anatomy before surgery. The effects of delayed diagnosis and the utility of magnetic resonance in diagnosis will be discussed.

Laparoscopic diagnosis of magnetic malrotation with fistula and volvulus.

INTRODUCTION: Most foreign bodies that a child ingests pass harmlessly through the gastrointestinal tract. However, ingesting multiple magnets places a child at risk for serious viscus injury. CASE DESCRIPTION: A 16-y-old boy swallowed multiple magnets and presented with abdominal pain and emesis. Upon laparoscopy, the boy was found to have malrotation with volvulus caused by a cecal magnet attracted to a gastric magnet, resulting in a gastrocecal fistula. DISCUSSION: We review the management of magnet ingestion with an emphasis on a high index of suspicion and the use of laparoscopy for diagnosis, as well as the consequences of a coexisting rotational anomaly.
