Bike Helmet Usage in the Most Disadvantaged Neighborhoods: A Focused Area for Trauma Prevention.

INTRODUCTION: There is a paucity of data to describe how neighborhood socioeconomic disadvantage (NSD) correlates with childhood injuries and outcomes. This study assesses the relationship of NSD to bicycle safety and trauma outcomes among pediatric bicycle versus automobile injuries. METHODS: Between 2008 and 2018, patients ≤18 y old with bicycle versus automobile injuries from a Level I pediatric trauma center were evaluated. Area Deprivation Index (ADI) was used to measure NSD. Patient demographics, injury, clinical data characteristics, and bike safety were analyzed. Traffic scene data from the Statewide Integrated Traffic Records System were matched to clinical records. Multivariate logistic regression was used to assess demographic characteristics related to helmet usage. RESULTS: Among 321 patients, 84% were male with a median age of 12 y [interquartile range 9-13], and 44% were of Hispanic ethnicity. Hispanic ethnicity was greater in the most disadvantaged ADI groups (P < 0.001). Mortality occurred in two patients, and most (96%) were discharged home. Of Statewide Integrated Traffic Records System matched traffic records, 81% were at locations without a bike lane. No differences were found in GCS, intensive care unit admission, or length of stay by ADI. Hispanic ethnicity and the highest deprivation group were independently associated with lower odds of wearing a helmet (AOR 0.35, 95% confidence interval 0.1-0.9, P = 0.03; AOR 0.33 95% confidence interval 0.17-0.62; P = 0.001), while patient age and sex were unrelated to helmet usage. CONCLUSIONS: Outcomes for bike versus auto trauma remains similar across ADI groups. However, bike helmet usage is significantly lower among Hispanic children and those from neighborhoods with greater socioeconomic disadvantage.

Modified laparoscopic gastrostomy tube placement in children: Does subcutaneous suture type matter?

BACKGROUND: Laparoscopic gastrostomy tube (GT) placement carries the risk of early tube dislodgement and is often modified with absorbable subcutaneously-tunneled transabdominal tacking sutures that can aid in tube replacement. However, these buried sutures may increase the risk of surgical site infection (SSI). This study sought to evaluate SSI rates associated with different types of transabdominal tacking sutures used in modified laparoscopic GT placement. METHODS: A single-institution, retrospective review was performed of all patients ≤18 years-old undergoing modified laparoscopic GT placement between September 2016 and March 2020. Patients were stratified into three groups by suture type used, and the primary outcome was SSI within six weeks of surgery. Demographic and perioperative data were analyzed by chi-square or Fisher's exact test. RESULTS: A total of 113 modified laparoscopic GT placements were performed at a median age of 9 months (interquartile range 3 months to 3 years). Prophylactic antibiotic use was similar between groups. Eleven patients (10%) developed an SSI, and all were treated with antibiotics alone. No SSIs were observed with the use of poliglecaprone suture (n = 46), and higher SSI rates were observed with use of polyglactin (n = 17) and polydioxanone (n = 51) suture (18% polyglactin vs. 16% polydioxanone vs. 0% poliglecaprone, p<0.05). No differences were observed in rates of early postoperative dislodgement, leakage, or granulation tissue. CONCLUSION: Absorbable braided and long-lasting monofilament transabdominal tacking sutures may increase risk of SSI following modified laparoscopic gastrostomy tube placement. In this cohort, the use of poliglecaprone (Monocryl) suture was associated with no SSIs and similar rates of postoperative dislodgement, leakage, and granulation tissue. LEVEL OF EVIDENCE: Treatment Study, Level III.

Just Stick a Scope in: Laparoscopic Ventriculoperitoneal Shunt Placement in the Pediatric Reoperative Abdomen.

BACKGROUND: Ventriculoperitoneal shunt (VPS) placement into the reoperative abdomen can be challenging due to intraperitoneal adhesions. Laparoscopic guidance may provide safe abdominal access and identify an area for optimal cerebrospinal fluid drainage. The study aim was to compare laparoscopic-assisted VPS placement to an "open" approach in patients with prior abdominal surgery. MATERIALS AND METHODS: A retrospective review was performed of children undergoing VPS placement into a reoperative abdomen from 2009-2019. Clinical data were collected, and patients undergoing laparoscopy (LAP) were compared to those undergoing an open approach (OPEN). RESULTS: A total of 120 children underwent 169 VPS placements at a median age of 8 y (IQR 2-15 y), and a mean number of two prior abdominal operations (IQR 1-2). Laparoscopy was used in 24% of cases. Shunt-related complications within 30 d were lower in the LAP group (0% versus 19%, P = 0.001), as were VPS-related postoperative emergency department visits (0% versus 13%, P = 0.003) and readmissions (0% versus 13%, P = 0.013). Shunt malfunction rates were higher (42% OPEN versus 25% LAP, P = 0.03) and occurred sooner in the OPEN group (median 26 versus 78 wk, P = 0.01). The LAP group demonstrated shorter operative times (63 versus 100 min, P < 0.0001), and the only bowel injury. Time to feeds, length of stay, and mortality were similar between groups. CONCLUSIONS: Laparoscopic guidance during VPS placement into the reoperative abdomen is associated with a decrease in shunt-related complications, longer shunt patency, and shorter operative times. Prospective study may clarify the potential benefits of laparoscopy in this setting.

Ovarian volume ratio is a reliable predictor of ovarian torsion in girls without an adnexal mass.

PURPOSE: The aims of this study were to identify ultrasound-based predictors of ovarian torsion in girls without an adnexal mass and establish a set of normal values for ovarian volume ratio (OVR). METHODS: A retrospective review was performed of all premenarchal patients ≥3 years of age with a normal pelvic ultrasound between January 2016 and January 2019. A comparison group of premenarchal girls presenting between 2011 and 2019 with torsion in the absence of an adnexal mass was utilized. RESULTS: Five-hundred and four premenarchal girls underwent pelvic ultrasound evaluation with a normal examination. The mean OVR was 1.6 ±â€¯0.7 (range 1.0-6.5). OVR did not vary with age (r = -0.06) as compared to ovarian width which increased steadily with age (r = 0.53, p < 0.001). OVR was increased in girls with torsion (7.6 vs 1.4, p < 0.0001), and by receiver operating characteristic (ROC) analysis a cutoff value of >2.5 demonstrated the best diagnostic accuracy of any predictive variable (sensitivity 100%, specificity 94%, AUC 0.991, p < 0.001). CONCLUSIONS: OVR is an excellent predictor of ovarian torsion in premenarchal girls without an adnexal mass. Unlike ovarian width, OVR does not increase with age, and a cutoff OVR > 2.5 demonstrates high sensitivity and specificity for identifying ovarian torsion in this population. TYPE OF STUDY: Study of diagnostic test. LEVEL OF EVIDENCE: Level III.

Patience is a virtue: Multiple preoperative visits are associated with decreased recurrence in pediatric pilonidal disease.

BACKGROUND/PURPOSE: This study aimed to compare preoperative management strategies for patients undergoing trephination for pilonidal disease and evaluate risk factors for recurrence. METHODS: A retrospective review was performed of children undergoing index surgical treatment with trephination for pilonidal disease between September 2017 and April 2019. Intraoperative and postoperative management were standardized. Demographic and perioperative data were collected and analyzed. RESULTS: One-hundred twenty patients were identified with a median follow-up time of 7.5 months (interquartile range 4.1-13.2 months). Overall, 24 (20%) patients had a postoperative recurrence of pilonidal disease. Patients with multiple preoperative surgery clinic visits were less likely to have recurrent disease compared to those seen only once preoperatively (11% vs 26%, p = 0.040). Compared to patients without recurrence, those who recurred went to the operating room sooner from the time of initial surgical consultation (32 days vs 54 days, p < 0.001). Perioperative antibiotics, history of acute infection, and prior drainage procedures were not risk factors for recurrence. CONCLUSIONS: Multiple preoperative clinic visits are associated with a lower recurrence rate in children undergoing trephination for pilonidal disease. An increased duration of preoperative medical management may be responsible for this finding. Prospective study is needed to confirm these findings and identify additional factors that influence recurrence. TYPE OF STUDY: Treatment Study. LEVEL OF EVIDENCE: III (Retrospective Comparative).

Trephination versus wide excision for the treatment of pediatric pilonidal disease.

BACKGROUND/PURPOSE: To evaluate outcomes of trephination compared to wide excision in children undergoing initial surgical treatment of pilonidal disease. METHODS: A retrospective review was conducted of patients undergoing initial pilonidal excision between September 2017 and September 2018. Operations were categorized as either trephination or wide excision via an open or closed-wound technique. Outcomes were evaluated and data analyzed by chi-squared and one-way ANOVA tests. RESULTS: One-hundred and five patients were identified, with a mean follow-up of 4.6 months. Trephination was performed in 57% of patients, and of the remaining patients undergoing wide excision, 62% of wounds were left open. There were no demographic differences among the three groups. Compared to both the open and closed techniques, trephination was associated with fewer wound complications (17% vs 29% vs 3%, respectively, p = 0.006), and postoperative visits (4.4 vs 2.4 vs 1.4, respectively, p < 0.001). There was no difference in recurrence rates among groups. CONCLUSION: Trephination for pilonidal disease in pediatric patients is associated with a lower wound complication rate and fewer postoperative visits compared to wide excision. Recurrence rates are similar among the various surgical methods. Further prospective study would be useful to describe long-term outcomes of patients undergoing trephination for pilonidal disease. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: III (retrospective comparative).

Premenarchal patients present differently: A twist on the typical patient presenting with ovarian torsion.

BACKGROUND/PURPOSE: The aim of this study was to characterize differences between pre- and postmenarchal females with ovarian torsion. METHODS: A single-center review was conducted of all nonneonatal pediatric patients with ovarian torsion from 2011 to 2018. Clinical data were compared between pre- and postmenarchal patients. RESULTS: One hundred and twenty-seven patients were identified, and 25% were premenarchal. Premenarchal patients were more likely to have a delay in diagnosis (38% vs 20%, p = 0.042), develop ovarian necrosis (34% vs 17%, p = 0.036), and present without an associated adnexal mass (44% vs 0%, p < 0.001). All patients without a mass (n = 14) were premenarchal and presented with ovarian asymmetry. Patients without an associated mass underwent oophoropexy in the majority of cases. There were no differences in postoperative complication or recurrence rates between groups. CONCLUSION: Premenarchal females with ovarian torsion can present differently than females postmenarche and often have a delay in diagnosis. Premenarchal females are more likely to undergo torsion without an associated adnexal mass and are at higher risk for ovarian necrosis. Oophoropexy is an appropriate treatment in the absence of an adnexal mass. A high-index of suspicion for ovarian torsion should be maintained for premenarchal females presenting with abdominal pain and an otherwise negative workup. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Preemptive Ladd Procedure in congenital diaphragmatic hernia and Abdominal Wall defects does not reduce the risk of future volvulus.

INTRODUCTION: Patients with congenital diaphragmatic hernia (CDH), gastroschisis, and omphalocele are prone to abnormalities of intestinal rotation and thus future midgut volvulus. Controversy exists whether routine preemptive Ladd procedure in this subgroup of asymptomatic patients is of value to reduce future volvulus. METHODS: The Pediatric Health Information System (PHIS) database was queried for neonates with CDH, gastroschisis, and omphalocele between January 2009 and September 2015. Standard univariate and multivariate analysis was completed to compare risk of volvulus between patients treated with a preemptive Ladd versus no Ladd (p<0.05). RESULTS: Seven thousand seven hundred forty-nine neonates with CDH (40%), gastroschisis (38%), omphalocele (14%), and abdominal wall malformation (NOS) (9%) were identified. Overall, 3.6% (n=279) had a preemptive. Thirty-two patients had subsequent volvulus. Ladd procedure did not reduce volvulus readmissions for any diagnosis and was associated with a significantly increased risk of volvulus for omphalocele patients (9.1% vs 0.1%, p<0.001). Overall, a Ladd procedure during the index admission was associated with a higher risk for volvulus (1.4% vs. 0.4%, p=0.021) and was associated with a 3.28 increased odds ratio of future volvulus (95% CI 1.12-9.68). CONCLUSION: Ladd procedure performed prophylactically in patients with CDH, gastroschisis, and omphalocele did not reduce subsequent volvulus. LEVEL OF EVIDENCE: III, Retrospective Comparative Study.
