The contemporary outcome of gastroschisis

Implementation of standardized feeding pathways for infants with gastroschisis to improve patient outcomes: A quality improvement project in a level IV surgical NICU

Gastroschisis is a leading cause of pediatric intestinal failure. Feeding guidelines may lead to improved patient outcomes including decreased time to reach full feeds, a reduction in the duration of parenteral nutrition, and reduced length of stay. However, there is limited evidence on what the ideal feeding guidelines are for this complex gastrointestinal diagnosis. In this quality improvement project, after completing a literature review, we created three pathways based on the complexity of the gastroschisis. We reviewed historical data without a defined feeding pathway/guideline to our newly created pathways in the intervention group. The study included 35 patients with varying degrees of gastroschisis complexity, consisting of 9 current patients (October 2021-December 2022) who were provided with defined feeding pathways and 26 historical patients before the protocol was implemented (January 2015-August 2021). There were no significant differences in the number of days required for full feeds between the two groups. However, the mean duration of parenteral nutrition was 18.9 days (95% CI, -31.8 to -7.0) shorter in the intervention group. Although not statistically significant, the patients in the intervention group had a mean length of stay that was 13.1 days (95% CI, -50.0 to 25.4) shorter than the historical group. The creation of standardized feeding guidelines for the gastroschisis population resulted in a statistically nonsignificant decrease in time to reach full enteral feeds, a statistically significant reduced duration of parenteral nutrition, and a statistically nonsignifiant decreased length of stay.

Gastroschisis in Sub-Saharan Africa: a scoping review of the prevalence, management practices, and associated outcomes

Gastroschisis is a congenital defect of the anterior abdominal wall characterized by a periumbilical abdominal wall defect with associated bowel protrusion. Limitations in the diagnosis and management of gastroschisis in Sub-Saharan African countries contribute to the high mortality rate. Few studies have been published despite its significant contribution to neonatal mortality in Sub-Saharan Africa. This review study explores the prevalence of gastroschisis, likewise the management and clinical outcomes. Full-text articles reporting the prevalence, management, and associated outcomes of gastroschisis in Sub-Saharan Africa were included. Data were extracted from databases such as PubMed, Google Scholar, and Ajol following a systematic search. The study was reported following the PRISMA-ScR guideline. A total of ten articles which included studies conducted from 1999 to 2022 fulfilled the criteria. The prevalence of gastroschisis varied widely, ranging from 0.026 to 1.75 with an overall mortality rate of 62.48%. Young maternal age is strongly associated with the incidence of gastroschisis. The study showed a slight male preponderance with a M: F ratio of 1.12:1. Staged closure with silos is the preferred method of management, it is explicitly linked to improved clinical outcomes. The prevalence rate and associated mortality of gastroschisis remain alarmingly high in most of the studies. There is a need for advanced diagnostic and management practices as well as increased awareness of gastroschisis to reduce mortality and improve survival outcomes.

Does Use of a Feeding Protocol Change Outcomes in Gastroschisis? A Report from the Midwest Pediatric Surgery Consortium

INTRODUCTION

 Gastroschisis feeding practices vary. Standardized neonatal feeding protocols have been demonstrated to improve nutritional outcomes. We report outcomes of infants with gastroschisis that were fed with and without a protocol.

MATERIALS AND METHODS

 A retrospective study of neonates with uncomplicated gastroschisis at 11 children's hospitals from 2013 to 2016 was performed.Outcomes of infants fed via institutional-specific protocols were compared with those fed without a protocol. Subgroup analyses of protocol use with immediate versus delayed closure and with sutured versus sutureless closure were conducted.

RESULTS

 Among 315 neonates, protocol-based feeding was utilized in 204 (65%) while no feeding protocol was used in 111 (35%). There were less surgical site infections (SSI) in those fed with a protocol (7 vs. 16%, p = 0.019). There were no differences in TPN duration, time to initial oral intake, time to goal feeds, ventilator use, peripherally inserted central catheter line deep venous thromboses, or length of stay. Of those fed via protocol, less SSIs occurred in those who underwent sutured closure (9 vs. 19%, p = 0.026). Further analyses based on closure timing or closure method did not demonstrate any significant differences.

CONCLUSION

 Across this multi-institutional cohort of infants with uncomplicated gastroschisis, there were more SSIs in those fed without an institutional-based feeding protocol but no differences in other outcomes.

Gastroschisis: a systematic review of diagnosis, prognosis and treatment

OBJECTIVES

The present systematic review aims to investigate the diagnosis, prognosis, delivery assistance, pregnancy results and postnatal management in gastroschisis.

STUDY DESIGN

The following data sources were evaluated: The CINAHL, Embase and MEDLINE/PubMed databases were searched, observational and intervention studies published over the past 20 years. The quality of the studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE).

RESULTS

A total of 3770 infants diagnosed with gastroschisis were included (44 studies); 1534 fetuses were classified as simple gastroschisis and 288 as complex gastroschisis. Intrauterine fetal demise occurred in 0.47% and elective termination occurred in 0.13%. Preterm delivery occurred in 23.23% and intrauterine growth restriction in 4.43%. Cesarean section delivery was performed in 54.6%. Neonatal survival was 91.29%. The main neonatal complications were: sepsis (11.78%), necrotizing enterocolitis (2.33%), short bowel syndrome (1.37%), bowel obstruction (0.79%), and volvulus (0.23%). Immediate surgical repair was performed in 80.1% with primary closure in 69%. The average to oral feeding was 33 (range: 11-124.5) days. Average hospital duration was 38 days and 89 days in neonates with simple and complex grastroschisis, respectively.

CONCLUSIONS

The present systematic review provides scientific data for counseling families with fetal gastroschisis.

Abdominal Wall Defects-Current Treatments

Gastroschisis and omphalocele reflect the two most common abdominal wall defects in newborns. First postnatal care consists of defect coverage, avoidance of fluid and heat loss, fluid administration and gastric decompression. Definitive treatment is achieved by defect reduction and abdominal wall closure. Different techniques and timings are used depending on type and size of defect, the abdominal domain and comorbidities of the child. The present review aims to provide an overview of current treatments.

Does prenatal counseling for pregnancies complicated by multiple fetal abnormalities concord with postnatal outcomes?

OBJECTIVE

In pregnancies complicated by multiple fetal abnormalities, our objective was to determine the degree of concordance between prenatal prognosis and postnatal outcomes.

METHOD

Retrospective cohort study of pregnancies with multiple fetal abnormalities referred to the Fetal Concerns Center of Wisconsin (FCCW) from 2015 to 2018. We reviewed records for anomalies, given prognostic severity, and postnatal outcomes. Prognostic severity was categorized as "likely mortality," "severe impairment," "moderate," and "mild" based on predetermined criteria.

RESULTS

In 85 pregnancies with multiple fetal abnormalities, 48% were given a prognosis of "likely mortality," and 19% were given a prognosis of "severe impairment." In pregnancies that were continued after being counseled as "likely mortality," this outcome was concordant in all but one case, despite medical interventions. In pregnancies counseled as "severe impairment," the more common outcome was mortality or severe impairment in 88% of cases and survival with severe impairment in 33% of cases. Postnatal outcomes were concordant with prenatal severity in 68% of the cases, more severe in 20% of the cases, and less severe in fewer than 5% of cases.

CONCLUSION

Prenatal predictions about severe outcomes are usually true in pregnancies complicated by multiple abnormalities. In cases of outcome discordance, outcomes tend to be more severe than predicted.

Reducing Gastroschisis Mortality: A Quality Improvement Initiative at a Ugandan Pediatric Surgery Unit

Introduction

With modern treatment, survival of gastroschisis exceeds 90% in high-income countries. Survival in these countries has been largely attributed to prenatal diagnosis, delivery at tertiary facilities with timely resuscitation, timely intervention, parenteral nutrition and intensive care facilities. In sub-Saharan Africa, due to lack of these facilities, mortality rates are still alarmingly high ranging from 75 to 100%. In Uganda the mortality is 98%.

Aim

The aim of this study was to reduce gastroschisis mortality in a feasible, sustainable way using a locally derived gastroschisis care protocol at a referring hospital in Western Uganda.

Methods

Data collection was performed from January to October 2018. Nursing staff were interviewed regarding the survival and management of gastroschisis babies. A locally derived protocol was created with staff input and commitment from all the team members.

Results

Four mothers absconded and 17 babies were cared for using the newly designed protocol. Seven survived and were well at one month post discharge follow-up, reducing the mortality for this condition from 98 to 59%.

Conclusion

A dedicated team with minimal resources can significantly reduce the mortality in gastroschisis by almost 40% using a locally derived protocol.

Burden and Outcomes of Neonatal Surgery in Uganda: Results of a Five-Year Prospective Study

BACKGROUND

Ninety-four percent of congenital anomalies occur in low- and middle-income countries. In Uganda, only three pediatric surgeons and three pediatric anesthesiologists serve more than 20 million children. This study estimates burden, outcomes, coverage, and economic benefit of neonatal surgical conditions in Uganda.

METHODS

A prospectively collected database was reviewed for neonatal surgical admissions from January 1, 2012, to December 31, 2017, at the only two sites with specialist pediatric surgical coverage. Outcomes were compared with high-income countries. Met and unmet need were estimated using disability-adjusted life years. Economic benefit was estimated using a value of statistical life-year approach.

RESULTS

For 1313 neonatal admissions, the median age of presentation was 3 d, overall mortality was 36%, and median distance traveled was 40 km. Anorectal malformations were most common (18%). Postoperative mortality was 24%. Mortality was significantly associated with surgical intervention (P < 0.0001). Met need was 4181 disability-adjusted life years per year, which corresponds to a $3.5 million net economic benefit to Uganda, with a potential additional benefit of $153 million if unmet need were fully addressed. Approximately 2% of the total need is met by the health care system.

CONCLUSIONS

Neonatal surgery is associated with improved survival for most conditions. Despite increases in workforce and infrastructure, a limited proportion of the need for neonatal surgery is currently being met. This is multifactorial, including lack of access to surgical care and severe shortages of workforce and infrastructure. Current and potential economic benefit to Uganda appears substantial.

Predicting Morbidity and Mortality in Neonates Born With Gastroschisis

BACKGROUND

Gastroschisis is an increasingly common congenital abdominal wall defect. Due to advances in neonatal critical care and early surgical management, mortality from gastroschisis and associated complications has decreased to less than 10% in most series. However, it has been recognized that the outcome of gastroschisis has a spectrum and that the disorder affects a heterogeneous cohort of neonates. The goal of this study is to predict morbidity and mortality in neonates with gastroschisis using clinically relevant variables.

METHODS

A multicenter, retrospective observational study of neonates born with gastroschisis was conducted. Neonatal characteristics and outcomes were collected and compared. Prediction of morbidity and mortality was performed using multivariate clinical models.

RESULTS

Five hundred and sixty-six neonates with gastroschisis were identified. Overall survival was 95%. Median hospital length of stay was 37 d. Sepsis was diagnosed in 107 neonates. Days on parenteral nutrition and mechanical ventilation were considerable with a median of 27 and 5 d, respectively. Complex gastroschisis (atresia, perforation, volvulus), preterm delivery (<37 wk), and very low birth weight (<1500 g) were associated with worse clinical outcomes including increased sepsis, short bowel syndrome, parenteral nutrition days, and length of stay. The composite metric of birth weight, Apgar score at 5 min, and complex gastroschisis was able to successfully predict mortality (area under the curve, 0.81).

CONCLUSIONS

Clinical variables can be used in gastroschisis to distinguish those who will survive from nonsurvivors. Although these findings need to be validated in other large multicenter data sets, this prognostic score may aid practitioners in the identification and management of at-risk neonates.

Single center protocol driven care in 150 patients with gastroschisis 1998-2017: collaboration improves results

PURPOSE

The treatment of gastroschisis (GS) using our collaborative clinical pathway, with immediate attempted abdominal closure and bowel irrigation with a mucolytic agent, was reviewed.

METHODS

A retrospective review of the past 20 years of our clinical pathway was performed on neonates with GS repair at our institution. The clinical treatment includes attempted complete reduction of GS defect within 2 h of birth. In the operating room, the bowel is evaluated and irrigated with mucolytic agent to evacuate the meconium and decompress the bowel. No incision is made and a neo-umbilicus is created. Clinical outcomes following closure were assessed.

RESULTS

150 babies with gastroschisis were reviewed: 109 (77%) with a primary repair, 33 (23%) with a spring-loaded silo repair. 8 babies had a delayed closure and were not included in the statistical analysis. Successful primary repair and time to closure had a significant relationship with all outcome variables-time to extubation, days to initiate feeds, days to full feeds, and length of stay.

CONCLUSION

Early definitive closure of the abdominal defect with mucolytic bowel irrigation shortens time to first feeds, total TPN use, time to extubation, and length of stay.

Surgical strategies in complex gastroschisis

Currently, the most important determinant of gastroschisis outcomes in high resource settings is whether the condition is associated with intestinal complications, such as atresia, necrosis, perforation, or volvulus. This form of the anomaly, known as complex gastroschisis, accounts for most of the mortality and a disproportionate burden of the morbidity from gastroschisis. There is some disagreement about what constitutes complex gastroschisis, and little consensus on the type and timing of surgical interventions. This article establishes a clear definition of complex gastroschisis. Surgical approaches to treatment of the diverse presentations of complex gastroschisis will be described and the timing of such interventions will be discussed. Contemporary outcomes of complex gastroschisis will be reviewed. Finally, a non-congenital intestinal complications that may arise in gastroschisis patients will be discussed.

Closure methods in gastroschisis

The expected outcome of gastroschisis has evolved from an almost certain death of the child prior to the use of parenteral nutrition to almost certain survival. The primary goal of the surgical intervention is return of eviscerated contents into the abdominal cavity. The optimal surgical technique is dependent on the status of the intestine and the accommodation of abdominal domain. In this review, the various surgical techniques for management are discussed as they have evolved. Ironically, a minimalist surgical intervention originally practiced due to the poor expected outcome is now being adopted as a minimalist surgical approach for abdominal wall closure associated with an expected excellent outcome.

Variability in outcomes after gastroschisis closure across U.S. children's hospitals

BACKGROUND

In patients undergoing gastroschisis closure, the effects of timing of closure and patient and hospital-level characteristics on length of stay (LOS) and time to enteral autonomy are unknown.

STUDY DESIGN

Using the Pediatric Health Information System, we compared neonates who underwent early (within 1day of birth) versus delayed (>1day after birth) gastroschisis closure from 2005 to 2013. We evaluated the relationship between time to closure and both LOS and days on total parenteral nutrition (TPN).

RESULTS

Of 4459 neonates with gastroschisis, 43.9% underwent early closure and 56.1% underwent delayed closure. Delayed closure, complicated gastroschisis, government insurance, lower birth weight, older age at closure, and complex chronic conditions were associated with longer LOS and days on TPN (all p<0.05). There was significant inter-hospital variability in both outcomes, after adjusting for patient- and hospital-level characteristics, including hospitals' gastroschisis and neonatal volumes, median age at closure, and percentages of complicated and delayed gastroschisis patients, (p<0.01).

CONCLUSION

Delayed gastroschisis closure is associated with longer LOS and duration of TPN, even after excluding complicated cases. Furthermore, after controlling for hospital volume, rate of complicated gastroschisis, and timing of closure, the persistent inter-hospital variability suggests that practice variability is partially responsible for these differences.

TYPE OF STUDY

Retrospective study.

Gastroschisis: A Review of Management and Outcomes

We performed an evidence-based review of the obstetrical management of gastroschisis. Gastroschisis is an abdominal wall defect, which has increased in frequency in recent decades. There is variation of prevalence by ethnicity and several known maternal risk factors. Herniated intestinal loops lacking a covering membrane can be identified with prenatal ultrasonography, and maternal serum α-fetoprotein level is commonly elevated. Because of the increased risk for growth restriction, amniotic fluid abnormalities, and fetal demise, antenatal testing is generally recommended. While many studies have aimed to identify antenatal predictors of neonatal outcome, accurate prognosis remains challenging. Delivery by 37 weeks appears reasonable, with cesarean delivery reserved for obstetric indications. Postnatal surgical management includes primary surgical closure, staged reduction with silo, or sutureless umbilical closure. Overall prognosis is good with low long-term morbidity in the majority of cases, but approximately 15% of cases are very complex with complicated hospital course, extensive intestinal loss, and early childhood death.

Outcome of isolated gastroschisis; an international study, systematic review and meta-analysis

OBJECTIVE

To determine outcome of children born with isolated gastroschisis (no extra-gastrointestinal congenital abnormalities).

STUDY DESIGN

International cohort study and meta-analysis.

PRIMARY OUTCOME

time to full enteral feeding (TFEF); secondary outcomes: Duration of mechanical ventilation, length of stay (LOS), mortality and differences in outcome between simple and complex gastroschisis (complex; born with bowel atresia, volvulus, perforation or necrosis). To compare the cohort study results with literature three databases were searched. Studies were eligible for inclusion if cases were born in developed countries with isolated gastroschisis after 1990, number of cases >20 and TFEF was reported.

RESULTS

The cohort study included 204 liveborn cases of isolated gastroschisis. The TFEF, median duration of ventilation and LOS was, 26days (range 6-515), 2days (range 0-90) and 33days (range 11-515), respectively. Overall mortality was 10.8%. TFEF and LOS were significantly longer (P<0.0001) and mortality was fourfold higher in the complex group. Seventeen studies, amongst the current study, were included for further meta-analysis comprising a total of 1652 patients. Mean TFEF was 35.3±4.4days, length of ventilation was 5.5±2.0days, LOS was 46.4±5.2days and mortality risk was 0.06 [0.04-0.07 95%CI]. Outcome of simple and complex gastroschisis was described in five studies. TFEF, ventilation time, LOS were significant longer and mortality rate was 3.64 [1.95-6.83 95%CI] times higher in complex cases.

CONCLUSIONS

These results give a good indication of the expected TFEF, ventilation time and LOS and mortality risk in children born with isolated gastroschisis, although ranges remain wide. This study shows the importance of dividing gastroschisis into simple and complex for the prediction of outcome.

Nutritional management and postoperative prognosis of newborns submitted to primary surgical repair of gastroschisis

OBJECTIVE

Gastroschisis is a defect of the abdominal wall, resulting in congenital evisceration and requiring neonatal intensive care, early surgical correction, and parenteral nutrition. This study evaluated newborns with gastroschisis, seeking to associate nutritional characteristics with time of hospital stay.

METHODS

This was a retrospective cohort study of 49 newborns undergoing primary repair of gastroschisis between January 1995 and December 2010. The newborns' characteristics were described with emphasis on nutritional aspects, correlating them with length of hospital stay.

RESULTS

The characteristics that influenced length of hospital stay were: (1) newborn small for gestational age (SGA); (2) use of antibiotics; (3) day of life when enteral feeding was started; (4) day of life when full diet was reached. SGA infants had longer length of hospital stay (24.2%) than other newborns. The length of hospital stay was increased by 2.1% for each additional day taken to introduce enteral feeding. However, slower onset of full enteral feeding acted as a protective factor, decreasing length of stay by 3.6%. The volume of waste drained by the stomach catheter in the 24h prior the start of enteral feeding was not associated with the timing of diet introduction or length of hospital stay.

CONCLUSION

Early start of enteral feeding and small, gradual increase of volume can shorten the use of parenteral nutrition. This management strategy contributes to reduce the incidence of infection and length of hospital stay of newborns with gastroschisis.

Enteral Feeding with Human Milk Decreases Time to Discharge in Infants following Gastroschisis Repair

OBJECTIVE

To assess the effect of enteral feeding with human milk on the time from initiation of feeds to discharge after gastroschisis repair through review of a multi-institutional database.

STUDY DESIGN

Infants who underwent gastroschisis repair between 1997 and 2012 with data recorded in the Pediatrix Medical Group Clinical Data Warehouse were categorized into 4 groups based on the percentage of days fed human milk out of the number of days fed enterally. Cox proportional hazards regression modeling was performed to determine the adjusted effect of human milk on the time from initiation of feeds to discharge.

RESULTS

Among 3082 infants, 659 (21%) were fed human milk on 0% of enteral feeding days, 766 (25%) were fed human milk on 1%-50% of enteral feeding days, 725 (24%) were fed human milk on 51%-99% of enteral feeding days, and 932 (30%) were fed human milk on 100% of enteral feeding days. Following adjustment, being fed human milk on 0% of enteral feeding days was associated with a significantly increased time to discharge compared with being fed human milk on 100% of enteral feeding days (hazard ratio [HR] for discharge per day, 0.46; 95% CI, 0.40-0.52). The same was found for infants fed human milk on 1%-50% of enteral feeding days (HR, 0.37; 95% CI, 0.32-0.41) and for infants fed human milk on 51%-99% of enteral feeding days (HR, 0.51; 95% CI, 0.46-0.57).

CONCLUSION

The use of human milk for enteral feeding of infants following repair of gastroschisis significantly reduces the time to discharge from initiation of feeds.

Predictive factors at birth of the severity of gastroschisis

AIM: To establish children born with gastroschisis (GS).

METHODS: We performed a retrospective study covering the period from January 2000 to December 2007. The following variables were analyzed for each child: Weight, sex, apgar, perforations, atresia, volvulus, bowel lenght, subjective description of perivisceritis, duration of parenteral nutrition, first nasogastric milk feeding, total milk feeding, necrotizing enterocolitis, average period of hospitalization and mortality. For statistical analysis, descriptive data are reported as mean ± standard deviation and median (range). The non parametric test of Mann-Whitney was used. The threshold for statistical significance was P < 0.05 (Two-Tailed).

RESULTS: Sixty-eight cases of GS were studied. We found nine cases of perforations, eight of volvulus, 12 of atresia and 49 children with subjective description of perivisceritis (72%). The mortality rate was 12% (eight deaths). Average duration of total parenteral nutrition was 56.7 d (8-950; median: 22), with five cases of necrotizing enterocolitis. Average length of hospitalization for 60 of our patients was 54.7 d (2-370; median: 25.5). The presence of intestinal atresia was the only factor correlated with prolonged parenteral nutrition, delayed total oral milk feeding and longer hospitalization.

CONCLUSION: In our study, intestinal atresia was our predictive factor of the severity of GS.

The Combination of Gastroschisis, Jejunal Atresia, and Colonic Atresia in a Newborn

We encountered a rare case of gastroschisis associated with jejunal atresia and colonic atresia. In our case, the jejunal atresia was not discovered for 27 days after the initial abdominal wall closure. The colonic atresia was not discovered for 48 days after initial repair of the gastroschisis secondary to the rarity of the disorder. Both types of atresia were repaired with primary hand-sewn anastomoses. Other than the prolonged parenteral nutrition and hyperbilirubinemia, our patient did very well throughout his hospital course. Based on our case presentation, small bowel atresia and colonic atresia must be considered in patients who undergo abdominal wall closure for gastroschisis with prolonged symptoms suggestive of bowel obstruction. Our case report also demonstrates primary enteric anastomosis as a safe, well-tolerated surgical option for patients with types of intestinal atresia.

Postnatal outcomes of infants with gastroschisis: a 5-year follow-up in a tertiary referral center in Brazil

OBJECTIVE

The aim of this study was to evaluate postnatal outcomes in fetuses with gastroschisis.

METHODS

This is a retrospective study (2009-2013) of patients with gastroschisis at the Hospital São Paulo (Federal University of São Paulo, Brazil).

RESULTS

A total of 44 infants with gastroschisis were examined. The mean maternal age was 21.1 years and mean gestational age at delivery was 36.1 weeks. Delivery occurred before 34 weeks in 13.6%, between 34 and 36 weeks and 6 d in 40.9%, and after 37 weeks in 45.5%. The mean birth weight was 2349 g, with 37.2% small-for-gestational age infants. The mean umbilical cord blood pH was 7.32. Bowel resection and delayed fascial closure was performed in 14.6% and 19.5%, respectively. The mean hospitalization time in the neonatal intensive care unit was 52.7 d. Neonatal infection was detected in 52.4%, with a positive blood culture; 77.3% of those cases were coagulase negative staphylococci. The overall rate of mortality was 25%; 18.2% before birth, 45.4% during the neonatal period, and 36.4% in infants. The main cause of postnatal death was septicemia (55.5%).

CONCLUSIONS

Despite advances in perinatal care and surgical techniques, infants with gastroschisis still present high rates of complications and death.

Treatment of bowel in experimental gastroschisis with a nitric oxide donor

OBJECTIVE

To reduce the harmful effect of bowel exposure to amniotic fluid in gastroschisis, we used the nitric oxide (NO) donor S-nitrosoglutathione (GSNO) in an animal model of gastroschisis and assessed the ideal concentration for treatment of changes in bowel.

STUDY DESIGN

Gastroschisis was surgically induced in rat fetuses on day 18.5 of gestation. The fetuses were divided into 5 groups (n = 12 animals/group): control (C), gastroschisis (G), gastroschisis + GSNO 5 μmol/L (GNO1), gastroschisis + GSNO 0.5 μmol/L (GNO2), and gastroschisis + GSNO 0.05 μmol/L (GNO3). On day 21.5 of gestation, fetuses were collected by cesarean delivery. Body and intestinal weight were measured and the bowels were either fixed for histometric and immunohistochemical study or frozen for Western blotting. We analyzed bowel morphometry on histological sections and expression of the NO synthase (NOS) enzymes by Western blotting and immunohistochemistry. Data were analyzed by analysis of variance or Kruskal-Wallis test when appropriate.

RESULTS

Morphological and histometric measurements of weight, diameter, and thickness of the layers of the intestinal wall decreased with GSNO treatment, especially in the GNO3 group, when compared with the G group (P < .05). The expression of neuronal NOS, endothelial NOS, and inducible NOS decreased mainly in GNO3 group compared to the G group (P < .05), with no difference compared to C group (P > .05).

CONCLUSION

Fetal treatment with 0.05 μmol/L GSNO resulted in significant improvement of bowel morphology in gastroschisis.

Outcomes and unmet need for neonatal surgery in a resource-limited environment: estimates of global health disparities from Kampala, Uganda

PURPOSE

Reported outcomes of neonatal surgery in low-income countries (LICs) are poor. We examined epidemiology, outcomes, and met and unmet need of neonatal surgical diseases in Uganda.

METHODS

Pediatric general surgical admissions and consults from January 1, 2012, to December 31, 2012, at a national referral center in Uganda were analyzed using a prospective database. Outcomes were compared with high-income countries (HICs), and met and unmet need was estimated using burden of disease metrics (disability-adjusted life years or DALYs).

RESULTS

23% (167/724) of patients were neonates, and 68% of these survived. Median age of presentation was 5days, and 53% underwent surgery. 88% survived postoperatively, while 55% died without surgery (p<0.001). Gastroschisis carried the highest mortality (100%) and the greatest mortality disparity with HICs. An estimated 5072 DALYs were averted by neonatal surgery in Uganda (met need), with 140,154 potentially avertable (unmet need). Approximately 3.5% of the need for neonatal surgery is met by the health system.

CONCLUSIONS

More than two thirds of surgical neonates survived despite late presentation and lack of critical care. Epidemiology and outcomes differ greatly with HICs. A high burden of hidden mortality exists, and only a negligible fraction of the population need for neonatal surgery is met by health services.

Gastroschisis--what should be told to parents?

Gastroschisis is a common congenital abdominal wall defect. It is almost always diagnosed prenatally thanks to routine maternal serum screening and ultrasound screening programs. In the majority of cases, the condition is isolated (i.e. not associated with chromosomal or other anatomical anomalies). Prenatal diagnosis allows for planning the timing, mode and location of delivery. Controversies persist concerning the optimal antenatal monitoring strategy. Compelling evidence supports elective delivery at 37  weeks' gestation in a tertiary pediatric center. Cesarean section should be reserved for routine obstetrical indications. Prognosis of infants with gastroschisis is primarily determined by the degree of bowel injury, which is difficult to assess antenatally. Prenatal counseling usually addresses gastroschisis issues. However, parental concerns are mainly focused on long-term postnatal outcomes including gastrointestinal function and neurodevelopment. Although infants born with gastroschisis often endure a difficult neonatal course, they experience few long-term complications. This manuscript, which is structured around common parental questions and concerns, reviews the evidence pertaining to the antenatal, neonatal and long-term implications of a fetal gastroschisis diagnosis and is aimed at helping healthcare professionals counsel expecting parents.

Outcomes of early versus late intestinal operations in patients with gastroschisis and intestinal atresia: results from a prospective national database

BACKGROUND

Gastroschisis may be complicated by intestinal atresia, necrosis, and/or perforation. In the absence of an urgent indication, intestinal procedures are often delayed to allow for bowel recovery. This practice has not been evaluated.

METHODS

We queried a prospective Canadian database of all patients with gastroschisis born between 2005 and 2011. Patients with intestinal atresia who underwent an intestinal operation during the first 21 days of life (EARLY GROUP) were compared with those who underwent operations later (LATE GROUP).

RESULTS

Of 629 gastroschisis patients, 78 (12.4%) had intestinal complications; 27 patients (4.3%) had intestinal operations for atresia without necrosis or perforation - 14 EARLY and 13 LATE. Baseline clinical parameters were similar between the two groups. There was a decreased incidence of the following complications in the EARLY group but none reached statistical significance: post-operative bowel obstruction (28.6% vs. 61.5%, p = 0.1); line sepsis (14.3% vs. 30.8 %, p = 0.4); and wound infection (14.3% vs. 46.1%, p = 0.1). Earlier tolerance of enteral feeding in the EARLY group was manifested by younger age at first enteral feeding (14.8 + 2.6 vs. 44.7 + 7.4 days, p = 0.002) and higher tolerance of enteral feeding at 28 days of life [less patients exclusively on TPN (28.6% vs. 61.5%, p = 0.06), and more patients on more than 50 cc kg(-1)day(-1) of enteral feeding (42.9% vs. 7.7%, p = 0.08)].

CONCLUSIONS

Early intestinal operations in patients with gastroschisis and intestinal atresia are not associated with increased complications, and allow patients to receive and tolerate enteral feeding earlier.

Intra-amniotic administration of urinary trypsin inhibitor preserves intestinal contractility in meconium induced intestinal damage in chick embryos with gastroschisis

BACKGROUND

Intestinal damage causes intestinal dysmotility in gastroschisis. Urinary trypsin inhibitor (UTI) has been shown to prevent intestinal damage in chick embryos with gastroschisis. The effect of intra-amniotic administration of UTI on intestinal motility in gastroschisis has not been investigated.

METHODS

Five-day-old fertilized chick embryos were used. Gastroschisis was created through the amniotic cavity without opening the allantoic cavity. There were six groups; control, gastroschisis only, gastroschisis plus meconium and three treatment groups. In the treatment groups, 100 IU/mL, 200 IU/mL and 400 IU/mL UTI were instilled into the amniotic cavity of the gastroschisis plus meconium embryos, respectively. Serosal thickness of the intestines in each group was measured histopathologically. The contractions of the intestines were evaluated by in vitro organ bath technique and the responses were expressed as maximal contraction induced by acetylcholine.

RESULTS

The serosal thickness was significantly increased in the gastroschisis plus meconium, 100 IU/mL, 200 IU/mL UTI groups compared to control and gastroschisis only groups. The serosal thickness of the 400 IU/mL UTI group was similar to control and gastroschisis only groups. Contractility of the intestines was diminished in the gastroschisis plus meconium, 100 IU/mL and 200 IU/mL UTI groups. There was no significant difference regarding contractility among control, gastroschisis only and 400 IU/mL UTI groups.

CONCLUSION

Intra-amniotic administration of UTI preserves intestinal contractility in chick embryos with gastroschisis. However, preservation of intestinal dysmotility by using UTI in the human gastroschisis cases needs further experimental and clinical trials.

Primary fascial closure versus staged closure with silo in patients with gastroschisis: a meta-analysis

BACKGROUND/PURPOSE

Gastroschisis is the most common congenital abdominal wall defect. Despite advances in the surgical closure of gastroschisis, consensus is lacking as to which method results in the best patient outcomes. The purpose of this meta-analysis was to compare short-term outcomes associated with primary fascial closure and staged repair with a silo in patients with gastroschisis.

METHODS

We reviewed Medline citations, as well as the Cochrane Database of Systematic Reviews, between January 1, 1996 and June 1, 2012. Articles were identified using the search term "gastroschisis" and [("treatment outcome" or "prognosis") or randomized controlled trials]. Case reports, reviews, letters, abstracts only, non-English abstracts, and studies that did not address at least one of the outcomes of interest were excluded from the meta-analysis. Two independent reviewers identified relevant articles for final inclusion. A standard data collection form created by the authors was used to extract study information, including study design, patient characteristics, and reported patient outcomes. The data were analyzed using standard meta-analytic techniques.

RESULTS

Twenty studies were included in the meta-analysis. In the five studies that selected closure method randomly or as a temporal shift in practice, silo was associated with better outcomes, with a significant reduction in ventilator days (p<0.0001), time to first feed (p=0.04), and infection rates (p=0.03). When all studies were included, primary closure was associated with improved outcomes.

CONCLUSIONS

Silo closure is associated with better clinical outcomes in the studies with the least selection bias. Larger prospective studies are needed to definitively determine the best closure technique.

Cholestasis and growth in neonates with gastroschisis

PURPOSE

The aim of this study was to determine the incidence of cholestasis and the correlation between cholestasis and weight-for-age z scores in parenteral nutrition-dependent neonates with gastroschisis.

METHODS

A single-center retrospective review of 59 infants born with gastroschisis from January 2000 to June 2007 was conducted. Demographic and clinical data were collected and analyzed. Subjects were divided into cholestatic and noncholestatic groups. Statistical analyses included the Student t test, Wilcoxon rank sum test, Fisher exact test, and a general linear model.

RESULTS

Fifty-nine neonates with gastroschisis were identified, and 16 (28%) of 58 patients developed cholestasis. Younger gestational age and cholestasis were found to be independently associated with weight-for-age z score in 30 of 58 patients with available long-term follow-up data.

CONCLUSIONS

Parenteral nutrition-dependent neonates with gastroschisis remain at considerable risk for the development of cholestasis. Both gestational age and cholestasis were found to be independent risk factors, predisposing these neonates to poor postnatal growth.

Contemporary 2-year outcomes of complex gastroschisis

PURPOSE

Outcomes of gastroschisis are influenced by associated intestinal complications. We present a detailed analysis of complex gastroschisis.

METHODS

A retrospective study of all patients with gastroschisis treated at 2 university neonatal intensive care units between January 1, 2001, and March 31, 2007, was performed.

RESULTS

Of 83 patients, 19 (23%) had complex gastroschisis, including atresias (68%), gangrene (37%), closing gastroschisis (32%), perforation (21%), strictures (21%), and volvulus (11%). Prenatal ultrasound did not predict complications. Fifty-three percent underwent primary closure. Duration of mechanical ventilation and total parenteral nutrition (TPN) was 14.4 ± 1.9 days and 90.7 ± 9.0 days, respectively. Enteral feeds started at 35.9 ± 4.6 days. Hospital stay was 104.4 ± 9.6 days. Patients underwent a median of 3 abdominal procedures (range, 2-5) before discharge. Ninety-five percent survived to discharge; 33% and 67% were discharged on TPN and gastrostomy feeds, respectively. Two-year survival was 89%, with 82% on full oral feeding, 12% on a combination of oral and gastrostomy feeding, and 1 patient (who received a liver/bowel transplant) on a combination of enteral and parenteral nutrition.

CONCLUSIONS

Complex gastroschisis continues to produce significant morbidity. However, most of the patients are TPN free by 2 years of age.

Use of paralysis in silo-assisted closure of gastroschisis

OBJECTIVE

To examine the association between pre-closure neuromuscular paralysis and time to final surgical closure for infants with gastroschisis undergoing silo reduction.

STUDY DESIGN

This study was an exploratory review of observational variables obtained from the Canadian Pediatric Surgery Network database. The focus was on the subset of infants with gastroschisis undergoing silo reduction between May 2005 and March 2009. Of the 186 infants, paralysis use could be ascertained for 167 infants (79 received pre-closure paralysis and 88 received none). Groups were compared by using statistical tests, with relationships explored using regression analysis.

RESULTS

Infants receiving paralysis took longer to achieve closure by an average of 3 days (8 versus 5 days; P < .001) and had greater mean number of ventilation days (12 versus 7 days; P < .001). The relationship between paralysis and days to closure remained after adjusting for other variables.

CONCLUSIONS

In infants with gastroschisis undergoing silo reduction, use of paralysis was associated with longer time to closure. Pre-closure paralysis should be carefully weighed in this population.

Monitoring intravesical pressure during gastroschisis closure. Does it help to decide between delayed primary or staged closure?

INTRODUCTION AND OBJECTIVE

Correction of gastroschisis may be accomplished by either primary or staged closure or even delayed primary closure after the use of a preformed silo. However, there is neither a consensus on the best approach nor established criteria to favor one method over the other. The aim of this paper was to investigate the role of intravesical pressure (IVP) as a tool to prevent abdominal compartment syndrome in newborns undergoing correction of abdominal wall defects.

METHODS

We retrospectively analyzed 45 newborns with gastroschisis in whom trans-operative intravesical pressure was used to choose between primary or staged closure. A threshold of 20 cm H(2)O was used and the outcomes between the two methods were compared.

RESULTS

In 24 children delayed primary closure was achieved while the remaining 21 underwent staged reduction and closure. There was no difference in the frequency of complications, time to begin oral feeding, length of parenteral nutrition or length of hospital stay between the children of the two groups. The incidence of temporary oliguria or anuria, averaged 33% and it was similar in both groups of children.

CONCLUSION

The data here presented suggests that monitoring intraoperative IVP during correction of gastroschisis may help to select children in whom staged closure is necessary, keeping their complication rate and overall outcome similar to that of children undergoing delayed primary closure. Further prospective studies should investigate more deeply the correlation between type of closure and the development of a compartment syndrome.

Infectious complications in the management of gastroschisis

BACKGROUND/PURPOSE

Neonates with gastroschisis make up an increasing proportion of prolonged surgical NICU admissions. While infectious complications are known to increase patient morbidity, it is unclear whether they vary according to abdominal closure method, or can be predicted by initial patient assessment.

METHODS

A national, prospective, disease-specific database was evaluated for episodes of wound infection (WI) and catheter-related infection (CRI). Antibiotic use and timing, as well as method and location of abdominal closure were studied. The gastroschisis prognostic score (GPS) was calculated and evaluated as a predictor of infectious complications.

RESULTS

Of 395 patients, 48 (12.6%) had a documented abdominal WI, and 59 patients (14.9%) had at least one episode of CRI-most commonly coagulase negative staphylococcus. Most abdominal closures took place within 6 h of admission (194 = 51.3%), while 132 (34.9%) were delayed greater than 24 h. The WI rate was greater in the delayed group (21.2 vs. 8.2%, p = 0.0006). The GPS was found to predict development of an infectious complication (WI + CRI, p = 0.04).

CONCLUSION

Infectious complications remain an important consideration in the management of gastroschisis. GPS correlates with the development of infectious complications. Prophylaxis for skin flora and early closure, when feasible, may reduce WI rates.

Gastroschisis with extracorporeal liver and stomach associated with sacrococcygeal teratoma and limb abnormalities

Gastroschisis is the herniation of abdominal viscera through a paramedian abdominal wall fusion defect without involvement of the umbilical cord. Evisceration usually contains intestinal loops and has no surrounding membrane. Rarely, herniation of other major viscera such as stomach and liver occurs, which makes the prognosis worse. Gastroschisis is usually not associated with sacrococcygeal teratoma. In the present report, a very rare case of gastroschisis associated with sacrococcygeal teratoma is described. The gastroschisis had complete evisceration of the stomach, bowel and extracorporeal liver. A large sacrococcygeal mass was located on the posteroinferior part of the trunk and gluteal region, and was completely external. The fetus also showed a malrotated lower limb and talipes equinovarus.

Effects of multidisciplinary prenatal care and delivery mode on gastroschisis outcomes

BACKGROUND/PURPOSE

This study examined the effects of multidisciplinary prenatal care and delivery mode on gastroschisis outcomes, with adjustment for key confounding variables.

METHODS

This retrospective cohort study included all gastroschisis patients treated at a single tertiary children's hospital between 1999 and 2009. Prenatal care, delivery mode (vaginal vs cesarean section before labor vs after labor), patient characteristics, and clinical outcomes were determined by chart review. Time to discontinuation of parenteral nutrition (PN) was the primary outcome of interest. Effects of multidisciplinary prenatal care and delivery mode were evaluated using Cox proportional hazards regression models that included gestational age, birth weight, sex, concomitant intestinal complications, and year of admission.

RESULTS

Of 167 patients included, 46% were delivered vaginally, 69% received multidisciplinary prenatal care, and median time to PN discontinuation was 38 days. On multivariable modeling, gestational age, uncomplicated gastroschisis, and year of admission were significant predictors of early PN independence. Delivery mode and prenatal care had no independent effect on outcomes, although patients receiving multidisciplinary prenatal care were more likely to be born at term (49% vs 27%, P = .01).

CONCLUSIONS

Gestational age and intestinal complications are the major determinants of outcome in gastroschisis. Multidisciplinary prenatal care may facilitate term delivery.

Evolution of critically ill patients with gastroschisis from three tertiary centers

OBJECTIVES AND INTRODUCTION: Gastroschisis is a congenital abdominal wall defect with increasing occurrence worldwide over the past 20-30 years. Our aim was to analyze the morbidity of newborns after gastroschisis closure, with emphasis on metabolic and hydroelectrolyte disturbances in patients at three tertiary university centers.

METHODS

From January 2003 to June 2009, the following patient data were collected retrospectively: (A) Background maternal and neonatal data: maternal age, prenatal diagnosis, type of delivery, Apgar scores, birth weight, gestational age and sex; (B) Surgical modalities: primary or staged closure; and (C) Hospital course: levels of serum sodium and levels of serum albumin in the two first postoperative days, number of ventilation days, other postoperative variables and survival. Statistical analyses were used to examine the associations between some variables.

RESULTS

163 newborns were included in the study. Primary closure of the abdominal defect was performed in 111 cases (68.1%). The mean serum sodium level was 127.4 ± 6.7 mEq/L, and the mean serum albumin level was 2.35 ± 0.5 g/dL. Among the correlations between variables, it was verified that hyponatremia and hypoalbuminemia correlated with the number of days on the ventilator but not with the number of days on total parenteral nutrition (TPN); mortality rate correlated with infection. The final survival rate was 85.9%.

CONCLUSION

In newborns with gastroschisis, more aggressive attention to hyponatremia and hypoalbuminemia would improve the outcome.

Does staged closure have a worse prognosis in gastroschisis?

INTRODUCTION

Correction of gastroschisis can be accomplished by primary or staged closure. There is, however, no consensus regarding the best approach or criteria to favor one method over the other has been established.

OBJECTIVE

To compare the outcome of primary and staged closure in newborns with gastroschisis using intravesical pressure (IVP) as the decision criterion.

PATIENTS & METHODS

We prospectively analyzed 45 newborns with gastroschisis. An IVP with a threshold of 20 cm H(2)O was used to indicate primary or staged closure, and the outcomes between the two methods were compared.

RESULTS AND DISCUSSION

Newborns in whom primary closure was feasible were born at a lower gestational age. There was no significant difference in the frequency of complications, time to begin oral feeding, length of parenteral nutrition or length of hospital stay. Compared with previous reports, our data showed higher rates of prenatal diagnosis and cesarean delivery, a lower average birth weight, a higher rate of small gestational age babies and a more frequent association with intestinal atresia. Conversely, our data showed a lower rate of postoperative necrotizing enterocolitis and a lower average length of hospital stay.

CONCLUSION

No significant difference was observed in the outcome of newborns who underwent primary closure or staged closure of gastroschisis when using an IVP below 20 cm H(2)O as the criterion for primary closure.

Sutureless elastic ring silo for the gastroschisis

Background: The definitive surgical management of gastroschisis is the return of the eviscerated abdominal content into the abdomen as soon as possible. Objectives: Assess the efficacy of using a sutureless elastic ring silo (SERS) for the management of gastroschisis. Methods: Neonates with gastroschisis were enrolled at Songklanagarind Hospital between January 2006 and December 2008. A primary repair (PR) was attempted in all cases. If this was not possible due to concerns about abdominal compartment syndrome, a stage abdominal closure with a silo pouch was fashioned: a traditional silo (TS) or SERS. When the bowel was completely reduced, a second-stage closure was performed in the operating room. Data collected included general demographic data, size of defect, associated anomalies, hospital course, mode of gastroschisis closure, duration of parenteral nutrition (PN) and ventilator, first feeding age, complications, and length of hospital stay (LOS). Results: Twenty-nine children with gastroschisis were treated (PR: 9, TS: 9, and SERS: 11). There were no differences (p >0.05) concerning gender, mode of delivery, APGAR scores, gestational age, birth weight, or defect size. A preformed silo was employed in 20 of 29 cases, TS in nine (31%), and SERS in 11 (38%) cases in an average operative time of 80.6 and 40 minutes, respectively, a significantly shorter operative time in the SERS (p =0.007). Overall, there were no differences (p >0.05) concerning duration of ventilator support (10.2 days), duration of PN (21.3 days), first feeding age (15 days), LOS (26.5 days), and complication. Conclusion: The use of a sutureless elastic ring silo with readily available inexpensive materials is simple, safe and efficacious in our setting.

Intestinal atresia in association with gastroschisis: a 26-year review

PURPOSE

We reviewed our experience with gastroschisis (GS) complicated by intestinal atresia over the last 26 years. Our aim was to determine the effect of different management strategies employed and the morbidity associated with this condition in our unit.

METHODS

A retrospective casenote review was carried out. Data regarding the operative management of the GS and atresia was recorded. Primary outcome measures included time to commence and establish full enteral feeds, duration of parenteral nutrition, complications and outcome.

RESULTS

Of 179 neonates with GS, 23 also had intestinal atresia. 13 underwent primary closure of the defect, 5 had patch closure and 5 had a silo placed. 4 atresias were 'missed' at first operation. The 19 recognised atresias were managed either by stoma formation, primary anastomosis or deferred management with subsequent primary anastomosis. There was wide variation in the outcomes of patients in each group.

CONCLUSION

Differences in outcome between the management strategies are likely to reflect an inherent variability in patient condition, site of atresia, and bowel suitability for anastomosis at first surgery, rather than the mode of surgical management. Individual management plans should be tailored to the clinical condition of each patient.

Inflammatory response in a rat model of gastroschisis is associated with an increase of NF-kappaB

Babies with gastroschisis have high morbidity, which is associated with inflammatory bowel injury caused by exposure to amniotic fluid. The objective of this study was to identify components of the inflammatory response in the intestine and liver in an experimental model of gastroschisis in rats. The model was surgically created at 18.5 days of gestation. The fetuses were exposed through a hysterotomy and an incision at the right of the umbilicus was made, exposing the fetal bowel. Then, the fetus was placed back into the uterus until term. The bowel in this model had macro- and microscopic characteristics similar to those observed in gastroschisis. The study was conducted on three groups of 20 fetuses each: gastroschisis, control, and sham fetuses. Fetal body, intestine and liver weights and intestine length were measured. IL-1beta, IL-6, IL-10, TNF-alpha, IFN-gamma and NF-kappaB levels were assessed by ELISA. Data were analyzed statistically by ANOVA followed by the Tukey post-test. Gastroschisis fetuses had a decreased intestine length (means +/- SD, 125 +/- 25 vs 216 +/- 13.9; P < 0.005) and increased intestine weight (0.29 +/- 0.05 vs 0.24 +/- 0.04; P < 0.005). Intestine length correlated with liver weight only in gastroschisis fetuses (Pearson's correlation coefficient, r = 0.518, P = 0.019). There were no significant differences in the concentrations of IL-1beta, TNF-alpha or IFN-gamma in the intestine, whereas the concentration of NF-kappaB was increased in both the intestine and liver of fetuses with gastroschisis. These results show that the inflammatory response in the liver and intestine of the rat model of gastroschisis is accompanied by an increase in the amount of NF-kappaB in the intestine and liver.

Gastroschisis: a third world perspective

PURPOSE

The incidence of gastroschisis is rising worldwide. In developed countries advances in neonatal intensive care (NICU) and the availability of total parenteral nutrition have improved survival for such patients, but in the third world mortality rates remain high. The aim of this study was to evaluate the impact of modern intensive care facilities on the mortality of babies with gastroschisis in Africa.

METHODS

A retrospective review of all neonates admitted with a diagnosis of gastroschisis at Inkosi Albert Luthuli Central Hospital in Durban over a 6-year period (2002-2007) was conducted.

RESULTS

A total of 106 babies with gastroschisis presented during the review period. The prevalence of gastroschisis amongst neonatal surgical admissions increased from 6% in 2003 to 15% in 2007. 72% of patients weighed less than 2.5 kg at birth and 64% were premature (<37 weeks gestation). 91% were "outborn" with 71% delivered vaginally. Median maternal age was 22.6 years and 57% of mothers were primiparous. Primary abdominal wall closure was possible in 74% of patients. The overall mortality was 43% with sepsis being the leading cause. Staged closure was associated with a higher mortality than primary closure.

CONCLUSION

The prevalence of gastroschisis amongst neonatal surgical admissions appears to be increasing. Most babies were "outborn" resulting in delays in diagnosis and referral for surgical management. Despite the availability of NICU and total parenteral nutrition the mortality remains high. Reduction in mortality will depend upon improvements in antenatal diagnosis, primary care and transportation, as well as a reduction in postsurgical sepsis.

Contemporary postnatal surgical management strategies for congenital abdominal wall defects

Early definitive closure of abdominal wall defects is possible in most cases. Staged reduction does offer distinct advantages, and mortality and morbidity may be better. Risk stratification may produce outcome and tailor management of difficult cases in the form of a clinical pathway. Stem cell technology may, in the future, offer the ideal allogenic prosthesis in complex cases.

Growth and neurodevelopment at 16 to 24 months of age for infants born with gastroschisis

OBJECTIVE

To examine growth, neurodevelopment and morbidity in infants with gastroschisis.

STUDY DESIGN

We enrolled all infants with gastroschisis treated at the North Carolina Children's Hospital from March 2003 through June 2005. Neonatal data were collected. Medical history, growth and neurodevelopment were assessed at 16 to 24 months.

RESULT

Of 24 infants, 17 completed follow-up. Weight and length were below the 10th percentile for five and six infants, respectively. Three infants scored less than 85 on the Bayley Scales of Infant Development, second edition. Small for gestational age (SGA) infants were smaller and had lower neurodevelopmental scores. Fourteen experienced continued bowel dysfunction; nine were rehospitalized.

CONCLUSION

One-third of infants with gastroschisis experience growth delay. Infants who are SGA are at higher risk, suggesting that postnatal growth may be influenced by fetal phenomena, and may not be modifiable. Neurodevelopment is not delayed. Continued bowel dysfunction is common.

Routine use of a SILASTIC spring-loaded silo for infants with gastroschisis: a multicenter randomized controlled trial

BACKGROUND

Retrospective studies have suggested that routine use of a preformed silo for infants with gastroschisis may be associated with improved outcomes. We performed a prospective multicenter randomized controlled trial to test this hypothesis.

METHODS

Eligible infants were randomized to (1) routine bedside placement of a preformed Silastic spring-loaded silo, with gradual reduction and elective abdominal wall closure, or (2) primary closure.

RESULTS

There were 27 infants in each group. There was no significant difference between groups with respect to age, weight, sex, Apgar scores, prenatal diagnosis, or mode of delivery. The total number of days on the ventilator was lower in the spring-loaded silo group, although it did not reach statistical significance (3.2 vs 5.3, P = .07). There was no significant difference between groups with respect to length of time on total parenteral nutrition, length of stay, or incidence of sepsis and necrotizing enterocolitis.

CONCLUSION

Routine use of a preformed silo was associated with similar outcomes to primary closure for infants with gastroschisis but with a strong trend toward fewer days on the ventilator. Use of a preformed silo has the advantage of permitting definitive abdominal wall closure in a more elective setting.

Infections in gastroschisis: organisms and factors

This study aimed to define the incidence, causative organisms and predisposing factors leading to infection related morbidity in newborns with gastroschisis. All gastroschisis patients admitted over the 5-year period (1999-2004) were retrospectively reviewed. Surveillance samples, wound, blood, urine and fecal cultures were analyzed. Duration of total parenteral nutrition, antibiotic therapy, feeding regimes and demographic data were also analyzed. Multiple logistic regression was employed using the SPSS system and p < 0.05 was considered as significant. Seventy-two neonates were identified with 53% having abnormal gut carriage mostly due to Enterobacter and Klebsiella. Wound infection occurred in 20% of cases. Abnormal gut carriage predisposed to the development of wound infection. Line sepsis occurred in 21% of neonates. Endogenous coagulase negative Staphylococcus caused 74% of septic episodes. There was no correlation between abnormal gut carriage and the development of line sepsis. Overall survival was 96%. The cause of infections in gastroschisis patients appears to be multifactorial. A multidisciplinary team can play an important role in reducing the incidence of infections. Strict aseptic protocols and auditing practice can be the invaluable tools in decreasing morbidity rates.

Gastroschisis closure: a technique for improved cosmetic repair

Gastroschisis closure is performed either primarily or after staged reduction of the prolapsed bowel. A technique for surgical closure of the abdominal wall defect is described which allows for an almost scarless appearance of the abdominal surface with preservation of a midline umbilicus.

Early elective cesarean delivery before 36 weeks vs late spontaneous delivery in infants with gastroschisis

PURPOSE

The aim of this study is to assess the value of early elective cesarean delivery for patients with gastroschisis in comparison with late spontaneous delivery.

METHODS

Analysis of infants with gastroschisis admitted between 1986 and 2006 at a tertiary care center was performed. The findings were analyzed statistically.

RESULTS

Eighty-six patients were involved in the study. This included 15 patients who underwent emergency cesarean delivery (EM CD group) because of fetal distress and/or bowel ischemia. The remaining 71 patients born electively were stratified into 4 groups. The early elective cesarean delivery (ECD) group included 23 patients born by ECD before 36 weeks; late vaginal delivery (LVD) group included 23 patients who had LVD after 36 weeks; 24 patients had LCD after 36 weeks because of delayed diagnosis that resulted in late referral; and 1 patient had early spontaneous vaginal delivery (EVD group) before 36 weeks. The mean time to start oral feeding, incidence of complications, and primary closure were significantly better in the ECD group than in the LVD group. The duration of ventilation and the length of stay were shorter in ECD group, but the difference was not statistically significant.

CONCLUSION

Elective cesarean delivery before 36 weeks allows earlier enteral feeding and is associated with less complications and higher incidence of primary closure (statistically significant).
