Pediatric ganglioneuroma, although benign, is typically treated by surgical resection. However, it is often asymptomatic and an incidental finding. We present an incidental multifocal ganglioneuroma diagnosed within the appendix and the subsequent treatment for this lesion. This intraoperative discovery led to the diagnosis of PTEN (phosphatase and tensin homolog) hamartoma syndrome which had otherwise gone undiagnosed.

Background We report a prospective randomized trial comparing primary closure (PC) to bedside silo and delayed closure (DC) for babies with gastroschisis. Materials and Methods Patients were randomized to PC versus DC. We excluded those with atresia/necrosis, Results A total of 38 patients were included from August 2011 to August 2016; 18 patients underwent DC and 20 PC. There were no differences in gestational age or birth weight. Fifty percent of PC patients were successfully closed with the rest closed at a median of 4 days (interquartile range [IQR]: 2–4 days). DC patients were closed at a median of 4 days after silo placement (IQR: 2–5.8 days). None of the patients in this series developed abdominal compartment syndrome after closure. Median LOS, median time to enteral tolerance, and median time on ventilation were not statistically different. Two patients (one DC and one PC) had bowel ischemia and necrosis following silo placement requiring reoperation. Four patients (two DC and two PC) were noted to have small umbilical defects; none have yet required operative correction. Conclusion There were no differences seen between PC and DC in LOS, time to enteral feeds, or ventilator times.

Penile adhesions are the most common complication after circumcision, although strategies to decrease them are poorly studied. We conducted a prospective, randomized trial comparing the use of 2-octyl cyanoacrylate (glue) skin adhesive to hydrophobic ointment after circumcision.Patients7years old undergoing circumcision were randomized to glue around the sutures and corona of the penis or antibiotic ointment. The primary outcome variable was postoperative penile adhesions. Utilizing a power of 0.8 and an alpha of 0.05, 168 patients were calculated for each arm. Because of high attrition, we planned to include up to 500 patients. Presence/absence of adhesions was evaluated 2-4weeks postop. Parents subjectively scored happiness, comfort, distress, and concern on a Likert scale 1-5.From 11/2012 through 7/2016, 409 patients were enrolled. Adhesion data were available on 243 patients. There was no difference between glue (16.8%) and those with antibiotic ointment (15.2%) (p=0.88) or in parental satisfaction across all areas measured. 165 patients were lost to follow-up, evenly distributed between the two groups (38% vs. 42%, p=0.49).The placement of 2-octyl cyanoacrylate skin adhesive does not decrease the rate of postoperative penile adhesions after circumcision. Parent satisfaction outcomes are similar.Treatment study.Level II.

Blunt abdominal trauma is an important cause of pediatric morbidity and mortality. The spleen and liver are the most common abdominal organs injured. Trauma to either organ can result in life-threatening bleeding. Controversy exists regarding which patients should be imaged and the correct imaging modality depending on the level of clinical suspicion for injury. Nonoperative management of blunt abdominal trauma is the standard of care for hemodynamically stable patients. However, the optimal protocol to maximize patient safety while minimizing resource utilization is a matter of debate. Adjunctive therapies for pediatric spleen and liver trauma are also an area of ongoing research. A review of the current literature on the diagnosis, management, and follow-up of pediatric spleen and liver blunt trauma is presented.

Omphalocele is an abdominal wall defect which can be classified as small, giant, or ruptured. Ruptured omphaloceles require prompt diagnosis and management to prevent associated morbidity and mortality and represent a challenging surgical condition. This review serves to define the etiology, diagnosis, initial resuscitation, and surgical therapy employed in the treatment of ruptured omphalocele. Resuscitation should focus on maintaining hydration and normothermia. Broad spectrum antibiotics should be initiated. Similar to giant omphaloceles, procedural intervention includes primary closure, silo, synthetic and biologic mesh, negative pressure wound therapy, and topical agents. Despite advances in neonatal care, the prognosis remains guarded and mortality is high.

Hypertrophic pyloric stenosis (HPS) is the most common diagnosis requiring surgery in infants. Electrolytes are used as a marker of resuscitation for these patients prior to general anesthesia induction. Often multiple fluid boluses and electrolyte panels are needed, delaying operative intervention. We have attempted to predict the amount of IV fluid boluses needed for electrolyte correction based on initial values.A single center retrospective review of all patients diagnosed with HPS from 2008 through 2014 was performed. Abnormal electrolytes were defined as chloride100mmol/L, bicarbonate ≥30mmol/L or potassium5.2 or3.1mmol/L. Patients with abnormal electrolytes were resuscitated with 20ml/kg saline boluses and continuous fluids at 1.5 times maintenance rate.During the study period 542 patients were identified with HPS. Of the 505 who were analyzed 202 patients had electrolyte abnormalities requiring IV fluid resuscitation above maintenance, and 303 patients had normal electrolytes at time of diagnosis. Weight on presentation was significantly lower in the patients with abnormal electrolytes (3.8 vs 4.1kg, p0.01). Length of stay was significantly longer in the patients with electrolyte abnormalities, 2.6 vs 1.9days (p0.01). Fluid given was higher over the entire hospital stay for patients with abnormal electrolytes (106 vs 91ml/kg/d, p0.01). The number of electrolyte panels drawn was significantly higher in patients with initial electrolyte abnormalities, 2.8 vs 1.3 (p0.01). Chloride was the most sensitive and specific indicator of the need for multiple saline boluses. Using an ROC curve, parameters of initial Cl(-)80mmol/L and the need for 3 or more boluses AUC was 0.71. Modifying the parameters to initial Cl(-) ≤97mmol/L and 2 boluses AUC was 0.65. A patient with an initial Cl(-)85 will need three 20ml/kg boluses 73% (95% CI 52-88%) of the time. A patient with an initial Cl(-) ≤97 will need two 20ml/kg boluses at a rate of 73% (95% CI 64-80%).Children with electrolyte abnormalities at time of diagnosis of HPS have a longer length of stay; require more fluid resuscitation and more lab draws. This study reveals high sensitivity and specificity of presenting chloride in determining the need for multiple boluses. We recommend the administration of two 20ml/kg saline boluses separated by an hour prior to rechecking labs in patients with initial Cl(-) value ≤97mmol/L. If the presenting Cl(-)85 three boluses of 20ml/kg of saline separated by an hour are recommended. If implemented these modifications have potential to save time by not delaying care for extraneous lab results and money in the form of fewer lab draws.

Introduction Pelvic angiography with embolization can successfully control hemorrhage in adults with pelvic fractures. However, evidence to support similar application in children is sparse. We describe our experience using angiography for pediatric pelvic fractures to further highlight the safety and efficacy of this treatment approach. Methods A retrospective review at a pediatric tertiary care center was performed from 2004 to 2014. Inpatients treated for a pelvic fracture were considered. Results A total of 216 patients were analyzed. Four patients (1.9%) underwent pelvic angiography. Three of these patients had active contrast extravasation on angiography and underwent successful embolization. All patients who underwent angiography showed computed tomography (CT) or clinical evidence of ongoing hemorrhage. No surgical intervention was needed after angiography. No complications of angiography occurred. Three patients who were found to have active extravasation on CT did not require angiography and were stabilized in the intensive care unit; two patients went on to have delayed operative repair. Mortality was 2.3%. All deaths were secondary to concomitant traumatic brain injury. No mortality occurred in patients undergoing pelvic angiography or those with pelvic contrast extravasation on CT. Conclusions Pelvic angiography is a useful treatment option in pediatric patients with pelvic fractures and clinical evidence of ongoing blood loss without other explanation. Contrast extravasation on CT scan alone may not require further intervention.

Literature reports worse outcomes for operations performed during off-hours. As this has not been studied in pediatric extracorporeal life support (ECLS), we compared complications based on the timing of cannulation..This is a retrospective review of 176 pediatric ECLS patients between 2004 and 2015. Patients cannulated during daytime hours (7:00 A.M. to 7:00 P.M., M-F) were compared to off-hours (nighttime or weekend) using t-test and Chi-square.The most common indications for ECLS were congenital diaphragmatic hernia (33 %) and persistent pulmonary hypertension (23 %). When comparing regular hours (40 %) to off-hours cannulation (60 %), there were no significant differences in central nervous system complications, hemorrhage (extra-cranial), cannula repositioning, conversion from venovenous to venoarterial, mortality on ECLS, or survival-to-discharge. The overall complication rate was slightly lower in the off-hours group (45.7 % versus 61.9 %, P = 0.034).Outcomes were not significantly worse for patients undergoing ELCS cannulation during off-hours compared to normal weekday working hours.

Intestinal malrotation is often diagnosed in infancy. The true incidence of malrotation outside of this age is unknown. These patients can present atypically or be asymptomatic and diagnosed incidentally. We evaluate the incidence, clinical presentation, ideal imaging, and intra-operative findings of patients with malrotation over 1 year of age. Retrospective review was conducted in patients older than 1 year, treated for malrotation at a single pediatric tertiary care center from 2000 to 2015. Data analyzed included demographics, presentation, imaging, intraoperative findings, and follow-up. Patients predisposed to malrotation were excluded. 246 patients were diagnosed with malrotation, of which 77 patients were older than 1 year of age. The most common presenting symptoms were vomiting (68%) and abdominal pain (57%). The most common method of diagnosis was UGI (61%). In 88%, the UGI revealed malrotation. 73 of 75 were confirmed to have malrotation at surgery. Intra-operatively, 60% were found to have a malrotated intestinal orientation and 33% with a non-rotated orientation. Obstruction was present in 22% with 12% having volvulus. Of those with follow-up, 58% reported alleviation of symptoms. Despite age malrotation should be on the differential given a variable clinical presentation. UGI should be conducted to allow for prompt diagnosis and surgical intervention.

Post-operative intra-abdominal abscess (PIAA) is the most common complication after appendectomy for perforated appendicitis (PA). Typically, intravenous antibiotics by a peripherally inserted venous catheter are utilized to treat the abscess. We sought to evaluate the role of oral antibiotics in this population. This is a retrospective review conducted of children between January 2005 and September 2015 with a PIAA. Demographics, clinical course, complications, and follow-up were analyzed using descriptive statistics. Comparative analysis was performed on those who were treated with oral vs IV antibiotics after diagnosis of PIAA. 103 children were included. Days of symptoms prior to admission were 3.2 ± 2.3 days with a WBC of 17.9 ± 6.4. Median time to diagnosis of PIAA from appendectomy was 7 days (7, 10). Mean total length of stay was 10 ± 3.4 days. 42% were treated with oral antibiotics (n = 43) versus 58% IV antibiotics (n = 60) at the time of discharge. We found a significant increase in total length of hospital stay (9.1 vs 10.7, p = 0.02) and number of medical encounters required for treatment (3.4 vs 4.4, p ≤ 0.01) in the IV group. PIAA treatment after appendectomy for PA can be treated with oral antibiotics with equivalent outcomes as IV antibiotic treatment, but with shorter length of hospitalizations and less medical encounters required.

Hepatic dysfunction in patients reliant on total parenteral nutrition (TPN) may benefit from cycled TPN. A concern for neonatal hypoglycemia has limited the use of cycled TPN in neonates less than 1 week of age. We sought to determine both the safety and efficacy of cycled TPN in surgical neonates less than 1 week of age. A retrospective chart review was conducted on surgical neonates placed on prophylactic and therapeutic cycled TPN from January 2013 to March 2016. Specific emphasis was placed on identifying incidence of direct hyperbilirubinemia and hypoglycemic episodes. Fourteen neonates were placed on cycled TPN; 8 were prophylactically cycled and 6 were therapeutically cycled. Median gestational age was 36 weeks (34, 37). Sixty-four percent (n = 9) had gastroschisis. There was no difference between the prophylactic and therapeutic groups in incidence of hyperbilirubinemia > 2 mg/dL (3 (37%) vs 5 (83%), p = 0.08) or the length of time to development of hyperbilirubinemia [24 days (4, 26) vs 27 days (25, 67), p = 0.17]. Time on cycling was similar though patients who were prophylactically cycled had a shorter overall time on TPN. Three (21%) infants had documented hypoglycemia, but only one infant became clinically symptomatic. Prophylactic TPN cycling is a safe and efficacious nutritional management strategy in surgical neonates less than 1 week of age with low rates of hypoglycemia and a shorter total course of TPN; however, hepatic dysfunction did not appear to be improved compared to therapeutic cycling.

Pediatric intussusception's first line treatment consists of fluoroscopic guided air enema reduction. Postprocedure, these patients are usually admitted overnight for observation. The purpose of our study was to document the results of emergency department (ED) observation and discharge protocol after successful reduction of ileocolic intussusception.A prospective observational study was conducted after implementation of an ED protocol for ileocolic intussusception from 10/2014 to 7/2017 and compared these patients to a historical cohort immediately prior to protocol initiation (10/2011-9/2014). Data collected included demographics, total time in the ED and hospital, enema reduction, recurrence, and requirement for operative intervention. Results reported as means with standard deviation and medians reported with interquartile ranges (IQR).115 patients were treated with the prospective protocol and were compared to a 90 patient historical cohort. Reduction was successful in 84%-89% of cases. Median hospital time after enema was shorter in the protocol group [4.8 h (4.25, 14.97) versus 19.7 h (13.9, 33.45), p 0.01]. Only 33% of patients were admitted following the protocol; the most common admission reason was persistent abdominal discomfort.ED observation and discharge after successful air enema reduction in children with ileocolic intussusception are safe, facilitate early discharge, and reduce hospital resource utilization.III.

The success of prospective randomized trials relies on voluntary participation, which has been perceived as a barrier for successful trials in children who rely on parental permission. We sought to identify the reasons parents decline child participation to understand potential limitations in the consent process. A prospective observational study was conducted in 92 patients asked to participate in prospective randomized trials between 2012 and 2015. Parental reasons for refusal were documented. The 92 refusals were distributed between studies investigating the management of circumcision, gastroschisis, pectus excavatum, appendicitis, pyloric stenosis, undescended testicles, abdominal abscess and gastroesophageal reflux. Reasons for refusal included preference of treatment path (37 %), inability to follow up (21 %), unspecified resistance to participate in research (18 %), preference to maintain independent surgeon decision (16 %), and desire for historically standard treatment (8 %). Of the families who opted to pursue a specific treatment arm rather than randomization, 35 % had prior experience with that treatment, 32 % had researched the procedure, 18 % wished to pursue the minimal intervention and 15 % did not specify. Parental preference of therapy is the most common reason for refusal of study participation. This variable could be influenced with more effective explanation of study rationale and existing equipoise.

Primary hyperparathyroidism due to adenoma or hyperplasia is often the cause of inappropriately elevated parathyroid hormone in patients with hypercalcemia. Intraoperative monitoring of parathyroid hormone serum concentrations is widely accepted in the adult population, ensuring adequate resection during primary operative exploration. Here, we describe a pediatric case report during which intraoperative hormone monitoring was crucial in directing the operative approach. This symptomatic patient had standard preoperative studies. However, despite an adequate resection of the identified hyperactive tissue, her intraoperative parathyroid hormone concentrations remained inappropriately elevated prompting further dissection of neighboring tissue. A parathyroid adenoma was successfully excised during the operation, preventing further invasive procedures. This report highlights the feasibility of monitoring intraoperatively parathyroid hormone levels in the pediatric population.

The risk of redo fundoplication has been demonstrated to be significantly higher in patients of younger age, those with ongoing retching, and those who underwent more extensive dissection of the esophageal hiatus at the initial operation. The purpose of this study was to review the management and outcomes of patients who required one or more re-operations for recurrence after laparoscopic fundoplication.After obtaining Institutional Review Board approval, we performed a retrospective review of all patients who underwent laparoscopic Nissen fundoplication from 2000 to 2013 and subsequently required a redo operation for recurrence. Patient demographics, neurologic impairment, interval time between re-operations, operative approach, use of mesh, and length of follow-up were analyzed. Two-tailed independent Student's t test was used to compare continuous variables, and two-tailed chi-squared test with Yates's correction (Fisher's exact test where appropriate) was used for discrete variables.Eighty-two patients (10.3% of the sample) required re-operation during the study period. The mean age at initial surgery was 1.8 ± 3.6 years. Fifteen patients (18.3%) required more than one re-operation. Of the 102 re-operations performed, 68 were successfully managed laparoscopically, 3 required conversion to an open procedure, and 31 were performed open from the outset. Of those patients requiring more than one re-operation, there was no difference in age, weight, use of mesh, or time to subsequent re-operations compared with patients that only required one redo fundoplication.The incidence of patients requiring another operation after a redo operation after an initial laparoscopic fundoplication is 18%. Patient demographics and time to re-operation have not been found to be predictive of which patient will require multiple re-operations for recurrence. However, younger patients and those with a shorter time to re-operation may increase the likelihood of failure.

Hemorrhagic shock has been studied extensively in the adult population, but evidence is lacking in the pediatric population. Unlike adults, pediatric patients tolerate hypovolemia with less hypotension until they have reached significant blood volume loss. It is imperative they receive prompt intravenous access, crystalloid resuscitation, followed by blood product transfusion. A hemoglobin goal of 7 g/dL has been translated to the pediatric population without evidence of poor outcomes. Massive transfusion protocols involving a 1:1:1 ratio of red blood cells:fresh frozen plasma:platelets has been recommended although further evidence is needed. With the transfusion of multiple blood products, consideration must be taken into account for the side effects, including electrolyte imbalance and lung injury.

Introduction The use of thoracic epidural is standard in adult thoracotomy patients facilitating earlier mobilization, deep breathing, and minimizing narcotic effects. However, a recent randomized trial in pediatric patients who undergo repair of pectus excavatum suggests patient-controlled analgesia (PCA) produces a less costly, minimally invasive postoperative course compared with epidural. Given that thoracotomy is typically less painful than pectus bar placement, we compared the outcomes of epidural to PCA for pain management after pediatric thoracotomy. Methods A retrospective review of 17 oncologic thoracotomies was performed at a children's hospital from 2004 to 2013. Data points included operative details, epidural or PCA use, urinary catheterization, days to regular diet, days to oral pain regimen, postoperative pain scores, length of stay, and anesthesia charges. Patients were excluded if they did not have epidural or PCA following thoracotomy. Results Six thoracotomies were managed with an epidural and 11 with a PCA. Three epidural patients were opiate naive compared with two with a PCA. The most common indication for thoracotomy was metastatic osteosarcoma (n = 13). When comparing epidural to PCA, there was no significant difference in days to removal of Foley catheter, regular diet, oral pain control, length of stay, or total operating room time. Postoperative pain scores were also comparable. The mean anesthesia charges were significantly higher in patients with an epidural than with a PCA. Conclusion Epidural catheter and PCA provided comparable pain relief and objective recovery course in children who underwent thoracotomy for oncologic disease; however, epidural catheter placement was associated with increased anesthesia charges, suggesting that PCA is a noninvasive, cost-effective alternative.

Esophageal foreign body retrieval is typically performed by rigid or flexible esophagoscopy. Despite evidence supporting the efficacy and safety of balloon extraction, it is rarely performed. We sought to establish the financial benefits of this minimally invasive approach.A retrospective review of 241 children with esophageal coins between 2011 and 2013 was performed. Coins were removed via endoscopy or fluoroscopic-guided balloon retrieval. Timing, symptoms, facility cost, and patient charges were compared.Two hundred patients had attempted balloon retrieval with 80% success. Forty-one patients went directly for operative removal. Patients with respiratory difficulty (p=0.05), wheezing (p0.01), or fever (p=0.03) were more often taken directly for endoscopic retrieval. The median cost and charges for attempted balloon extraction were $484 and $1647. The median cost and charges for primary endoscopy were $1834 and $6746. The median total cost and charges of attempted balloon extraction including ED, OR, transport, admission, and balloon retrieval were $1231 and $3539 versus $3615 and $12,204 in the primary endoscopy group (p0.001, p0.001). Seventeen percent of patients who underwent attempted balloon retrieval were admitted prior to removal compared to 76% who underwent primary endoscopy (p0.001).Fluoroscopic guided balloon extraction of esophageal coins is a financially prudent choice which shortens hospital stay.III.Retrospective treatment and economic study.

Surgical wound classification has emerged as a measure of surgical quality of care, but scant data exist in the era of minimally invasive procedures, especially in children. The aim of this study is to examine the surgical site infection (SSI) rate by wound classification during common pediatric surgical procedures.A retrospective analysis of the 2013 Pediatric-National Surgical Quality Improvement Program (Peds-NSQIP) dataset was conducted. Patients undergoing pyloromyotomy, cholecystectomy, ostomy reversal, and appendectomy were included. Wound classification, SSI rate, reoperation, and readmission were analyzed.A total of 10,424 records were included. Pyloromyotomy, a clean case, had a 0.7% SSI rate, while ostomy reversal, a clean contaminated case, had an SSI in 6.9% of cases. Appendectomy for nonperforated acute appendicitis and laparoscopic cholecystectomy for cholecystitis, both contaminated cases, had SSI rates of 2.1% and1%, respectively. Appendectomy for perforated appendicitis, a dirty procedure, had a 9.1% SSI rate, below the expected40% for dirty cases. Reoperations and readmission rates ranged from1% to 9% and increased with case complexity.Current wound classifications systems do not reflect surgical risk in children and remain questionable tools for benchmarking surgical care in children. Role of readmissions and reoperations as quality of care indices needs further investigation.

Although TEG directs effective resuscitation in adult surgical patients, pediatric data are lacking. We performed a retrospective comparative review of the effect of TEG on blood product utilization and outcomes following pediatric liver transplantation in 38 patients between 2008 and 2014. Diagnoses, laboratory values, fluid and blood product use, and outcomes were examined. Nineteen patients underwent liver transplantation prior to the implementation of TEG, and 19 had perioperative TEG. The most common indications for transplant were BA (n = 14), HB (n = 7), and metabolic disorders (n = 7). Intraoperative blood loss, urine output, fluid and blood product use were similar between groups. However, the use of fresh frozen plasma decreased significantly in TEG patients within the first 24 hours (29 vs 0 mL/kg, P

Introduction The recent increased awareness of the dangers of opioids in the United States has highlighted the need to minimize narcotics and identify nonopioid options for pain control after surgery. With evidence suggesting that intravenous acetaminophen (IVA) can be an opioid sparing option, we conducted a prospective, randomized trial that evaluated the effect of IVA on the postoperative pain course of children with perforated appendicitis. Materials and Methods After IRB approval, children with perforated appendicitis were randomized to receive postoperative IVA with the standard patient/nurse-controlled analgesia (PCA) or to receive the PCA alone. All patients were treated according to an evidence-based treatment protocol. The primary outcome was duration of time on PCA. Results Eighty-two patients were analyzed from 7/14 to 11/15. There was no statistically significant difference in the time to transition from the PCA to oral pain medications for children given IVA compared with children not receiving IVA (76.4 ± 32.5 versus 86.7 ± 49.3 hours; p = 0.73). Children in the IVA group had no statistically significant difference in intravenous narcotics delivered and pain scores compared with the non-IVA group. There was no significant difference in the amount of oral narcotics between both groups (2.8 ± 2.4 versus 2.9 ± 2.5; p = 0.88). Patients who received IVA had higher medication charges ($3752.7 ± 1618.3 vs. $1198.19 ± 521.51; p Conclusion Children given IVA showed no difference in the transition time off the PCA and to oral pain medications after laparoscopic appendectomy for perforated appendicitis.

Complex gastroschisis with bowel necrosis poses an operative challenge. Surgeons must weigh the decision between resection versus preservation of ischemic bowel. As one of the leading causes of short bowel syndrome, aggressive resection in complicated gastroschisis subjects children to prolonged dependence on parenteral nutrition and its attendant complications. Herein, we describe a novel technique aimed towards bowel preservation in complex gastroschisis patients with severe bowel ischemia with the ultimate goal for enteral autonomy.

Background We conducted a randomized trial comparing 1 and 2-stage laparoscopic orchiopexy for intra-abdominal testes. During recruitment, it became apparent that most patients with non-palpable testes do not require vascular division. In this report, we outline the location and quality of testes found during operative exploration in patients who consented for the study but were not randomized. Methods Analysis was performed on 80 patients undergoing operative exploration for non-palpable testes between 2007 and 2014. The location and pathology of undescended testes were analyzed. Results There were 87 preoperative non-palpable testes in 80 patients that were consented but not randomized to 1 or 2 stage orchiopexy with vascular division. Forty (46%) of nonrandomized testes were atrophic or absent, and 47 (54%) were normal in appearance. Sixty eight testes were evaluated via laparoscopy. The most common location for normal (81%) and absent/atrophic (70%) testes was the inguinal canal. Atrophic testes were more often left sided (72.5%) with normal testes equally divided. Patients with atrophic or absent testicles were more likely to have a closed internal ring (p Conclusion This study demonstrates the majority of patients undergoing operative exploration for non-palpable testes will not require vascular division, and instead would be either atrophic or able to undergo traditional orchiopexy.

Background Minimally invasive bar repair for pectus patients produces substantial pain which dictates the post-operative hospital course. We have data from 2 randomized trials comparing epidural catheter placement to patient controlled analgesia. The purpose of this study was to compare the outcomes of patients who were enrolled in the trials to those that did not participate in the trials. Methods A retrospective chart review was performed on patients not enrolled in the trials to compare to the prospective datasets from October 2006 to June 2014. Perioperative outcomes were examined. Results There were 135 patients in a study protocol (IS) and 195 patients that were not enrolled in a study (OS). Comparing the entire IS and OS groups, length of stay was less in the IS group, as was time to regular diet. Average pain scores, operative time and complication rates were not significantly different between the groups. Of the IS patients a significantly lower number of patients had epidural failure, requiring substitution of a PCA for pain control. Conclusions There are benefits derived from participating in our randomized trials comparing epidural to patient controlled analgesia after bar placement for pectus excavatum regardless of which arm is utilized.

Introduction Gastroschisis (GS) is a common abdominal wall defect necessitating neonatal surgery and intensive care. We hypothesized that inborn patients had improved outcomes compared to patients born at an outside hospital (outborn) and transferred for definitive treatment. Methods A single center, retrospective chart review at a pediatric tertiary care center was performed from 2010 to 2015. All patients whose primary surgical treatment of GS was performed at this center were included. We compared patients delivered within our center (inborn) to patients delivered outside of our center and transferred for surgical care (outborn). Babies with complicated gastroschisis were excluded. Results During the study period 79 patients with GS were identified. Of these, 53 were inborn and 26 were outborn. Sixteen patients were excluded for complicated GS. The rate of complicated GS was higher in the outborn group (32%) compared to the inborn population (11%) (p=0.03). Duration of stay, readmission rate and time on TPN were all significantly decreased for inborn patients, while time to definitive closure was similar. Mortality was 0% for both inborn and outborn patients. Conclusion Patients with uncomplicated GS seem to benefit from delivery with immediate pediatric surgical care available eliminating the need for transfer. Level of evidence III

In 2011, we established a dedicated center for patients with chest wall deformities. Here, we evaluate the center’s effect on patient volume and management. A retrospective review of 699 patients with chest wall anomalies was performed.

Professionalism requires that doctors acknowledge their errors and figure out how to avoid making similar ones in the future. Over the last few decades, doctors have gotten better at acknowledging mistakes and apologizing to patients when a mistake happens. Such disclosure is especially complicated when one becomes aware of an error made by a colleague. We present a case in which consultant surgeons became aware that a colleague seemed to have made a serious error. Experts in surgery and bioethics comment on appropriate responses to this situation.

An upper gastrointestinal (UGI) series is a standard preoperative test for patients being evaluated for gastrostomy tube placement. We have recently begun to question the value of the radiation-exposing series in patients who tolerate gastric feeds.A retrospective review was conducted in patients who underwent laparoscopic gastrostomy tube placement between 2000 and 2012. Demographics, indication for gastrostomy tube, comorbidities, preoperative imaging, and nutrition were analyzed. Patients with foregut pathology and those who underwent prior gastrointestinal surgery were excluded.Among 695 patients who underwent laparoscopic gastrostomy tube placement, the most common indications were failure to thrive (53%), neurologic disorder (25%), and dysphagia (12%). A UGI series was obtained for 420 patients (60%). Of these, 96 were found to have abnormalities (reflux, aspiration, anatomic). However, only 2 of these patients (0.3%) had a change in management, with 1 patient undergoing the Ladd procedure and 1 having negative diagnostic laparoscopy for suspected malrotation. In the subset analysis of 256 patients tolerating goal gastric feeds, 161 (63%) had a preoperative UGI series with only 2 patients (1.2%) having a resultant change in operative management: 1 undergoing the Ladd procedure and 1 having negative diagnostic laparoscopy. Of the 275 patients who did not have a preoperative UGI series, 1 patient (0.4%) was found to have malrotation postoperatively after two coins became lodged in the duodenum. This patient subsequently underwent an elective Ladd procedure.We found minimal impact of an UGI series during evaluation for gastrostomy alone. These studies may be able to be reserved for those with clear clinical indications.

BACKGROUND Rib fractures (RFx) remain the most prevalent injury in an elderly population that will increase from 40 to 81 million for the next 30 years. We sought to create an accurate cost-effective algorithm to triage elderly patients with RFx that accounted for both frailty and trauma burden. METHODS Retrospective analysis evaluated 400 patients older than 55 years with RFx admitted to a level 1 trauma center from 2007 to 2012. Comorbidities included chronic obstructive pulmonary disease, congestive heart failure, tobacco use, obesity, and nutrition and functional status. Trauma burden included RFx, tube thoracostomy, pulmonary contusions, and spine and extremity fractures. Patients with Glasgow Coma Scale scores lower than 13, thoracoabdominal surgery, or deaths from other causes were excluded. Comparative analysis used bivariate and logistic regression. Variables contributing to intubation (INT) and pneumonia (PNA) were then used to create a scoring system to predict the need for intensive care unit (ICU) admission. RESULTS Six variables increased the risk for INT or PNA: chronic obstructive pulmonary disease, low albumin, assisted status, tube thoracostomy, Injury Severity Score, and RFx (p < 0.05). These six variables and congestive heart failure (odds ratio, 1.9; p = 0.06) were used to create a predictive model with the following scores assigned respectively: 1.4, 1.1, 1, 0.9, 0.1(n), 0.1(n), and 0.6. A score lower than 3.7 had a sensitivity and specificity of 78.5% and 78.9%. The negative predictive value was 94.5% for INT or PNA, suggesting a low risk for ICU requirement. Ninety-two ICU admissions had a score lower than 3.7. Forty had no other indication for ICU admission aside from RFx. These patients had an average ICU length of stay of 1.7 days, resulting in an increased cost of $2,200 per patient. CONCLUSION A scoring system combining frailty and trauma burden may provide more accurate and cost-effective triage of the elderly trauma patient with RFx. Further prospective studies are required to verify our scoring system. LEVEL OF EVIDENCE Prognostic and epidemiologic study, level III.

The leading cause of death in the pediatric population is trauma, of which pelvic injuries make up a very small percentage. Trauma to the pelvis can result in multiple injuries to the bony pelvis, rectum, bladder, and or the urethra. Although mortality in the pediatric population is typically secondary to associated injuries, pelvic hemorrhage can be a life-threatening event. The management of patients with complex pelvic injuries requires a multidisciplinary approach in order to achieve the best possible outcomes.

Purpose Historically, a chest radiograph was obtained after central line placement in the operating room. Recent retrospective studies have questioned the need for this radiograph. The prevailing current practice at our center is to order chest radiograph only for symptomatic patients. This study examines the outcomes of selective chest radiography after fluoroscopic guided central line placement. Methods After obtaining institutional review board approval, a single institution retrospective chart review of patients undergoing central venous catheter placement by the pediatric surgery or interventional radiology service between January 2010 and July 2014 was performed. Outcome measures included CXR within 24h of catheter placement, reason for chest radiograph, complication, and complication requiring intervention. Results In the study population 622 catheters were placed under fluoroscopy. A chest radiograph was performed in 118 (19%) patients within 24h of the line placement with 25 (4%) of these patients being symptomatic in the recovery room. One patient required chest tube for shortness of breath and pleural effusion. Four symptomatic patients (0.6%) were found to have a pneumothorax, none of which required chest tube placement. There were no re-operations because of mal-position of the catheter. In the 504 patients with no postoperative chest x-ray, there were no adverse outcomes. At our institution the current average charge of a chest radiograph is $283, thus we produced savings of $142,632 for the study period without adverse events. Conclusion After placement of central venous catheter under fluoroscopic guidance, a chest radiograph is unlikely to be helpful in an asymptomatic patient.

Chemical fibrinolysis has been shown to be as effective as surgical debridement for the treatment of pediatric empyema. However, no studies effectively evaluate antibiotic treatment. We evaluated antibiotic utilization among different treatments of pediatric empyema.This is a retrospective review of 169 empyema patients who underwent chemical and/or mechanical fibrinolysis at a dedicated children's hospital from 2005-2013. Data points included duration of therapy, cultures, presence of necrosis or abscess, and adverse drug reactions. Immunocompromised patients and those with additional foci of infection were excluded.Twenty-seven patients underwent video-assisted thoracoscopic surgery (VATS), 123 had chemical fibrinolysis via tube thoracostomy with tissue plasminogen activator (tPA), and 19 had tPA followed by VATS. The mean (± standard deviation) duration of total antibiotic therapy was 25.7 ± 6.5 d; following a 24 h afebrile period of 19.4 ± 6.3 d. Patients who had tPA had a significantly shorter duration of parenteral antibiotic therapy when compared with primary VATS (9.2 ± 3.6 d versus 11.6 ± 5.5 d, P = 0.04) and VATS following tPA (9.2 ± 3.6 d versus 14.3 ± 8.1 d, P0.01). Patients with necrosis or abscess (n = 26) had an increased total duration of antibiotics (29.3 ± 5.7 d versus 25.1 ± 6.4 d, P0.01). Seventy patients (41%) had an adverse reaction related to antibiotic use.Patients with empyema currently receive a protracted variable course of antibiotic therapy influenced by primary treatment and the presence of necrosis or abscess. With a high incidence of adverse reactions, a standardized protocol with truncated treatment duration should be considered.

Background Although the safety of same day discharge (SDD) after laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis (SC) and biliary dyskinesia (BD) in adults has been well documented in the literature, the same data in the pediatric population are lacking. We have recently instituted a protocol for SDD after LC for SC and BD, and this study is an analysis of our initial experience. Methods A retrospective chart review of all patients who underwent LC for BD and SC in our institution from January 2011–July 2014 was performed. Results A total of 227 LC were performed for SC and BD during the study period. Approximately 25% (n = 57) of patients were in the SDD group. The remaining 75% (n = 170) of patients were admitted at least overnight stay (ONS) for the following reasons: medical 16.5% (n = 28), surgery ending too late 4.1% (n = 7), or clinical care habits 79.4% (n = 135). Comparing the SDD group with ONS group, no differences were found in the complication rate, readmissions, or follow up before scheduled appointment. Length of stay was significantly less for the SDD group than for the ONS. A trend for more SDDs was observed as time elapsed from initiation of the protocol. Also, earlier completion of surgery trended toward SDD. Conclusions SDD appears safe for pediatric patients undergoing LC for BD or SC. The main obstacles to discharge were time of surgery completion and clinical care habits, both of which improved as comfort level with SDD grew among the staff.
