Medical procedures and outcomes of Japanese patients with trisomy 18 or trisomy 13: analysis of a nationwide administrative database of hospitalized patients

Trends in the survival of patients with trisomy 13 from 1995 to 2021: A population study in Japan

It remains unclear whether recent changes in the prognosis and management of patients with trisomy 13 impact patient survival. We investigated changes in survival of patients with trisomy 13 in Japan. Data from the Vital Statistics Database in Japan was retrieved to examine the association of sex, surgical history, and years of birth and death with changes in survival patterns in 1164 patients with trisomy 13 between 1995 and 2021. The rates of deaths due to trisomy 13 increased from 9.8% to 23.1% in those over 1 year of age and from 7.3% to 19.2% in those within 24 h of birth between 1995 and 2021. The median survival time was longer in 2009-2021 than in 1996-2008 (40 vs. 84 days, p < 0.001). The median survival time and the rate of patients with surgical history increased from 91 days and 16.0% in 1996-2008 to 179 days and 28.0% in 2009-2021, respectively. Median survival time among patients with trisomy 13 has increased over the last 26 years, with almost 1 in 3 patients currently surviving for more than 1 year. The increased surgical intervention rate might have contributed to this improvement.

The American Association for Thoracic Surgery (AATS) 2023 Expert Consensus Document: Recommendation for the care of children with trisomy 13 or trisomy 18 and a congenital heart defect

OBJECTIVES

Recommendations for surgical repair of a congenital heart defect in children with trisomy 13 or trisomy 18 remain controversial, are subject to biases, and are largely unsupported with limited empirical data. This has created significant distrust and uncertainty among parents and could potentially lead to suboptimal care for patients. A working group, representing several clinical specialties involved with the care of these children, developed recommendations to assist in the decision-making process for congenital heart defect care in this population. The goal of these recommendations is to provide families and their health care teams with a framework for clinical decision making based on the literature and expert opinions.

METHODS

This project was performed under the auspices of the AATS Congenital Heart Surgery Evidence-Based Medicine Taskforce. A Patient/Population, Intervention, Comparison/Control, Outcome process was used to generate preliminary statements and recommendations to address various aspects related to cardiac surgery in children with trisomy 13 or trisomy 18. Delphi methodology was then used iteratively to generate consensus among the group using a structured communication process.

RESULTS

Nine recommendations were developed from a set of initial statements that arose from the Patient/Population, Intervention, Comparison/Control, Outcome process methodology following the groups' review of more than 500 articles. These recommendations were adjudicated by this group of experts using a modified Delphi process in a reproducible fashion and make up the current publication. The Class (strength) of recommendations was usually Class IIa (moderate benefit), and the overall level (quality) of evidence was level C-limited data.

CONCLUSIONS

This is the first set of recommendations collated by an expert multidisciplinary group to address specific issues around indications for surgical intervention in children with trisomy 13 or trisomy 18 with congenital heart defect. Based on our analysis of recent data, we recommend that decisions should not be based solely on the presence of trisomy but, instead, should be made on a case-by-case basis, considering both the severity of the baby's heart disease as well as the presence of other anomalies. These recommendations offer a framework to assist parents and clinicians in surgical decision making for children who have trisomy 13 or trisomy 18 with congenital heart defect.

Treatment courses and outcomes of oesophageal atresia in patients with trisomy 18: a case series of 271 patients from a nationwide database in Japan

OBJECTIVE

To describe characteristics, treatments and clinical outcomes of patients with trisomy 18 and oesophageal atresia, using a nationwide database in Japan.

DESIGN

Descriptive study using a retrospective cohort.

SETTING

A nationwide inpatient database including 90% of hospitals with neonatal intensive care units in Japan.

PATIENTS

Patients hospitalised within a day after birth for both oesophageal atresia and trisomy 18 between July 2010 and March 2020.

INTERVENTIONS

Radical surgery for oesophageal atresia.

MAIN OUTCOME MEASURES

Characteristics, treatment course and outcomes.

RESULTS

Among 271 patients with both oesophageal atresia and trisomy 18, 70 patients underwent radical surgery for oesophageal atresia. Patients who underwent radical surgery were less likely to have severe cardiac anomalies (17% vs 32%; p=0.020), but more likely to undergo cardiac surgery (21% vs 9.5%; p=0.012) than those who did not. The overall in-hospital mortality was lower (54% vs 79%; p<0.001) and the median age at death was higher (210 days vs 39 days; p<0.001) in patients who underwent radical surgery than the others. Postoperative mortality within 30 days after radical surgery was 5.7%. Patients who underwent radical surgery were likely to be discharged to home (50% vs 18%; p<0.001), whereas the age at home discharge (median 314 days vs 216 days; p=0.19) and the requirement for each home treatment did not differ significantly by radical surgery.

CONCLUSION

This study provides information that will aid the clinical decision-making process for patients with oesophageal atresia and trisomy 18. Radical surgery may be a safe and feasible treatment option.

"She was finally mine": the moral experience of families in the context of trisomy 13 and 18- a scoping review with thematic analysis

INTRODUCTION

The value of a short life characterized by disability has been hotly debated in the literature on fetal and neonatal outcomes.

METHODS

We conducted a scoping review to summarize the available empirical literature on the experiences of families in the context of trisomy 13 and 18 (T13/18) with subsequent thematic analysis of the 17 included articles.

FINDINGS

Themes constructed include (1) Pride as Resistance, (2) Negotiating Normalcy and (3) The Significance of Time.

INTERPRETATION

Our thematic analysis was guided by the moral experience framework conceived by Hunt and Carnevale (2011) in association with the VOICE (Views On Interdisciplinary Childhood Ethics) collaborative research group.

RELEVANCE

This article will be of interest and value to healthcare professionals and bioethicists who support families navigating the medically and ethically complex landscape of T13/18.

Impact of tracheostomies on the long-term survival of patients with trisomy 13 syndrome

In this retrospective cohort study, we investigated the impact of tracheostomies on the long-term survival of children with trisomy 13 syndrome at a Japanese tertiary pediatric center. We compared survival and survival to discharge rates between patients who underwent tracheostomies during their NICU stays (T group, n = 8) and those who did not (non-T group, n = 11). A total of 19 patients enrolled. Median survival in all patients was 673 (266-1535) days. Significant differences in the 1-, 2-, and 3-year survival rates were found between the T and the non-T groups (100% vs. 46%, p = 0.018; 88% vs. 18%, p = 0.006; 63% vs. 9%, p = 0.041, respectively). The survival to discharge rate was higher in the T versus non-T group (75% vs. 45%, p = 0.352). This study highlights a significantly higher long-term survival of patients with trisomy 13 syndrome who underwent tracheostomies during their NICU stays.

Outcomes Following Laparoscopic Versus Open Surgery for Pediatric Intussusception: Analysis Using a National Inpatient Database in Japan

BACKGROUND

Laparoscopic surgery for pediatric intussusception has recently become more common as an alternative to open surgery. However, the differences in outcomes between laparoscopic and open surgery remain unclear. Thus, this study aimed to compare short-term surgical outcomes and recurrence rates between patients treated with laparoscopic and open surgery for pediatric intussusception.

METHODS

Patients aged <18 years who underwent laparoscopic (n = 192) and open (n = 416) surgery for intussusception between April 2016 and March 2021 were retrospectively identified using a Japanese nationwide inpatient database. Propensity-score overlap weighting analyses were conducted to compare the outcomes between the laparoscopic and open surgery groups. The outcomes included in-hospital morbidity, reoperation, readmission for intussusception, bowel resection, the diagnosis of Meckel's diverticulum, duration of anesthesia, postoperative length of hospital stay, and total hospitalization costs.

RESULTS

The laparoscopic surgery group was older, heavier, and had fewer congenital malformations and emergency admissions than the open surgery group did. Overlap weighting analyses showed no significant differences in in-hospital morbidity (odds ratio [95% confidence interval], 0.88 [0.35-2.23]), reoperation (1.88 [0.24-14.9]), readmission for intussusception within 30 days (0.80 [0.12-5.30]) and 1 year (0.90 [0.28-2.93]), bowel resection (0.69 [0.46-1.02]), the diagnosis of Meckel's diverticulum (0.97 [0.50-1.90]), duration of anesthesia (difference, 11 [-1-24] minutes), postoperative length of stay (difference, -1.9 [-4.2-0.4] days), or total hospitalization costs (difference, 612 [ -746-1970] US dollars) between the groups.

CONCLUSIONS

In this large nationwide cohort, no significant differences in outcomes were observed between laparoscopic and open surgery. Laparoscopic surgery is an acceptable treatment option for pediatric intussusception.

Perioperative outcomes of laparoscopically assisted anorectoplasty versus conventional procedures for anorectal malformation: a retrospective nationwide database study

PURPOSE

This study aimed to compare the perioperative outcomes of laparoscopically assisted anorectoplasty (LAARP) and conventional procedures (CPs) for anorectal malformation (ARM) using a national inpatient database in Japan.

METHODS

Using the Diagnosis Procedure Combination database, we identified patients who underwent anorectoplasty for high- or intermediate-type ARMs from 2010 to 2019. Primary outcomes were postoperative rectal prolapse, anal stenosis, and general complications. Secondary outcomes were the duration of anesthesia and length of hospital stay. We performed 1:2 propensity score-matched analyses to compare the outcomes between the LAARP and CP groups.

RESULTS

We identified 1005 eligible patients, comprising 286 and 719 patients who underwent LAARP and CP, respectively. The propensity score-matched groups included 281 patients with LAARP and 562 with CP. The LAARP group showed a higher proportion of rectal prolapse (21.4% vs. 8.5%; odds ratio, 2.91; 95% confidence interval [CI], 1.89-4.48; p < 0.001) and longer duration of anesthesia (462 min vs. 365 min; difference, 90 min; 95% CI 43-137; p < 0.001) than the CP group. No significant differences were found in other outcomes.

CONCLUSION

LAARP had worse outcomes than CP in terms of rectal prolapse. Thus, we propose that LAARP may require technical refinement to improve patient outcomes.

Surgical history and outcomes in trisomy 13 and 18: A thirty-year review

BACKGROUND

Patients with Trisomy 13(T13) and 18(T18) have many comorbidities that may require surgical intervention. However, surgical care and outcomes are not well described, making patient selection and family counseling difficult. Here the surgical history and outcomes of T13/ T18 patients are explored.

METHODS

A retrospective review of patients with T13 or T18 born between 1990 and 2020 and cared for at a tertiary children's hospital (Riley Hospital for Children, Indianapolis IN) was conducted, excluding those with insufficient records. Primary outcomes of interest were rates of mortality overall and after surgery. Factors that could predict mortality outcomes were also assessed.

RESULTS

One-hundred-seventeen patients were included, with 65% T18 and 35% T13. More than half of patients(65%) had four or more comorbidities. Most deaths occurred by three months at median 42.0 days. Variants of classic trisomies (mosaicism, translocation, partial duplication; p = 0.001), higher birth weight(p = 0.002), and higher gestational age(p = 0.01) were associated with lower overall mortality, while cardiac(p = 0.002) disease was associated with higher mortality. Over half(n = 64) underwent surgery at median age 65 days at time of first procedure. The most common surgical procedures were general surgical. Median survival times were longer in surgical rather than nonsurgical patients(p<0.001). Variant trisomy genetics(p = 0.002) was associated with lower mortality after surgery, while general surgical comorbidities(p = 0.02), particularly tracheoesophageal fistula/esophageal atresia(p = 0.02), were associated with increased mortality after surgery.

CONCLUSIONS

Trisomy 13 and 18 patients have vast surgical needs. Variant trisomy was associated with lower mortality after surgery while general surgical comorbidities were associated with increased mortality after surgery. Those who survived to undergo surgery survived longer overall.

Surgical and obstetric outcomes of breast cancer surgery during pregnancy: a nationwide database study in Japan

PURPOSE

Although the incidence of breast cancer during pregnancy is increasing, little is known about short-term outcomes following breast cancer surgery during pregnancy. We aimed to compare the characteristics and outcomes of breast cancer surgery with and without pregnancy, and describe the obstetric outcomes following surgery.

METHODS

The data of 249,257 female patients aged < 60 years who underwent breast cancer surgery between July 2010 and March 2020 were analyzed using a nationwide Japanese database; we generated a 1:10 matched-pair cohort (260 and 2597 patients with and without pregnancy, respectively) matched according to age and treatment year. We conducted multivariable analyses to compare surgical procedures and outcomes, adjusting for potential confounders in the matched-pair cohort. Additionally, we described the obstetric outcomes of patients with pregnancy.

RESULTS

Patients with pregnancy were more likely to undergo total mastectomy [odds ratio: 1.48 (95% confidence interval: 1.13-1.94)] and axillary dissection [1.62 (1.17-2.24)], but less likely to undergo reconstruction [0.14 (0.07-0.31)], than patients without; however, postoperative complications, postoperative length of stay, and total hospitalization costs did not differ significantly with pregnancy. Additionally, some pregnant patients experienced premature delivery [n = 18 (6.9%)] and miscarriage [n = 4 (1.5%)], and 31 of 101 patients in the third trimester at breast cancer surgery underwent a cesarean section.

CONCLUSION

This study demonstrated significant differences regarding surgical procedures; however, there were no significant differences regarding surgical outcomes between patients who underwent breast cancer surgery with and without pregnancy. Obstetric outcomes following breast cancer surgery were also reported.

Perinatal Outcomes of Fetuses and Infants Diagnosed with Trisomy 13 or Trisomy 18

OBJECTIVES

To identify factors associated with prenatal, perinatal, and postnatal outcomes, and determine medical care use for fetuses and infants with trisomy 13 (T13) and trisomy 18 (T18).

STUDY DESIGN

This population-based retrospective cohort study included all prenatal and postnatal diagnoses of T13 or T18 in the greater Cincinnati area from January 1, 2012, to December 31, 2018. Overall survival, survival to hospital discharge, medical management, and maternal, fetal, and neonatal characteristics are analyzed.

RESULTS

There were 124 pregnancies (125 fetuses) that were identified, which resulted in 72 liveborn infants. Male fetal sex and hydrops were associated with a higher rate of spontaneous loss. The median length of survival was 7 and 29 days, for infants with T13 and T18, respectively. Of the 27 infants alive at 1 month of age, 13 (48%) were alive at 1 year of age. Only trisomy type (T13), goals of care (comfort care), and extremely low birthweight were associated with a shorter length of survival. A high degree of variability existed in the use of medical services, with 28% of infants undergoing at least 1 surgical procedure and some children requiring repeated (≤29) or prolonged (>1 year) hospitalizations.

CONCLUSIONS

Although many infants with T13 or T18 did not survive past the first week of life, nearly 20% lived for more than 1 year with varying degrees of medical support. The length of survival for an infant cannot be easily predicted, and surviving infants have high health care use throughout their lifespans.

Survival outcomes of very low birth weight infants with trisomy 18

Trisomy 18 (T18) is one of the most commonly diagnosed aneuploidies leading to poor survival outcome. However, little is known about the dual risk of T18 and very low birth weight (VLBW, weighing <1500 g at birth). We aimed to investigate the survival and clinical features of VLBW infants with T18. In this observational cohort study, infants with T18 admitted to the neonatal intensive care unit in Kyushu University Hospital from 2000 to 2019 were eligible. Among 30 infants with T18 who were enrolled as study participants, 11 (37%) were born with VLBW. VLBW infants had lower gestational age (34.4 vs. 39.4 weeks, p < 0.01) and a higher incidence of esophageal atresia (64% vs. 11%, p < 0.01) than non-VLBW infants. The proportions of patients who underwent any surgery (55% vs. 5%, p < 0.01) and positive pressure ventilation (82% vs. 32%, p = 0.02) were higher in VLBW than non-VLBW infants. One-year overall survival rate (45% vs. 26%, p = 0.32 by log-rank test) did not differ between the two groups. In conclusion, being born at VLBW may not be fatal for infants with T18 undergoing active interventions.

A validated model for prediction of survival to 6 months in patients with trisomy 13 and 18

Congenital heart disease is exceedingly prevalent in trisomy 13 and 18. Improved survival following congenital heart surgery has been reported, however, mortality remains significantly elevated. Utilizing inpatient data on trisomy 13 and 18 from the 2003-2016 Pediatric Health Information System database, a survival model was developed and validated using data from the California Perinatal Quality Care Collaborative and the California Office of Statewide Health Planning and Development. The study cohort included 1,761 infants with trisomy 13 and 18. Two models predicting survival to 6 months of age were developed and tested. The initial model performed excellently, with a c-statistic of 0.87 and a c-statistic of 0.76 in the validation cohort. After excluding procedures performed on the day of death, the revised model's c-statistic was 0.76. Certain variables, including cardiac surgery, gastrostomy, parenteral nutrition, and mechanical ventilation, are predictive of survival to 6 months of age. This study presents a model, which potentially can inform decision-making regarding congenital heart surgery.

Population-Based Analysis of Secular Trends in Age at Death in Trisomy 18 Syndrome in Japan from 1975 to 2016

INTRODUCTION

Despite changes in prenatal diagnostic methods and perceptions regarding the prognosis of and treatment options for patients with trisomy 18 syndrome, data on the secular changes in patient survival are limited. This study aimed to investigate the survival pattern for such patients.

METHODS

To investigate the general patient survival patterns, we used data from the vital statistics database of deaths in Japan from 1975 to 2016. We described demographic factors, such as sex, gestational age at delivery, and surgical history, for patients whose primary cause of death was trisomy 18 syndrome.

RESULTS

The proportions of deaths within 24 h of birth (4.0% in 1975-1980 to 21.9% in 2011-2016) and at age ≥1 year (8.9% in 1975-1980 to 17.7% in 2011-2016) increased. The median survival time was higher for females, infants born after 37 weeks of gestation, and those who received surgical intervention. The median survival time tripled among patients who received surgical intervention (61.5 days in 1995-2005 to 182.5 days in 2006-2016), and the proportion of such patients increased (from 3.8% in 1995 to 24.1% of the entire affected population in 2016).

DISCUSSION/CONCLUSION

In Japan, the median survival time of infants with trisomy 18 increased over time, and the proportion of death within 24 h and at ≥1 year increased. Greater acknowledgement of the possible benefits of surgical intervention likely led to the increased provision of interventions and contributed to the increased survival time.

Impacts of surgical interventions on the long-term outcomes in individuals with trisomy 18

OBJECTIVE

We aim to clarify whether surgical interventions can contribute to improve the long-term outcomes among individuals with trisomy 18.

METHODS

We retrospectively studied 69 individuals with trisomy 18 admitted to 4 tertiary neonatal centers between 2003 and 2017. A cohort was divided into two groups: subjects with surgical interventions and conservative treatments. We compared the rates of survival and achieving homecare between the groups.

RESULTS

Gestational age and birth weight were 37 (27-43) weeks and 1,700 (822-2,546) g, respectively. There were 68 patients with congenital heart disease and 20 patients with digestive disease. Surgical interventions including cardiac and digestive surgery were provided in 41% of individuals. There was no difference in gestational age (p=0.30), birth weight (p=0.07), gender (p=0.30), and fetal diagnosis (p=0.87) between the groups. During the median follow up duration of 51 (2-178) months, overall survival rates in 6, 12 and 60 months were 57%, 43% and 12%, respectively. Survival to hospital discharge occurred in 23 patients, and the rates of achieving homecare in 1, 6, and 12 months are 1%, 18% and 30%, respectively. There was no significant difference in survival rate (p=0.26) but in the rate of achieving home care (p=0.02) between the groups. Cox hazard analysis revealed that prenatal diagnosis (hazard ratio 0.30, 95%CI: 0.13-0.75), cardiac surgery (hazard ratio 2.40, 95%CI:,1.03-5.55), and digestive surgery (hazard ratio 1.20, 95%CI: 1.25-3.90) were related to the rate of achieving homecare.

CONCLUSION

Aggressive surgical interventions contribute not to the long-term survival but to achieve homecare among individuals with trisomy 18.

Prevalence and clinical characteristics of children with medical complexity in Tottori Prefecture, Japan: A population-based longitudinal study

OBJECTIVES

To investigate the prevalence and background of children with medical complexity (CMC) and its secular trend in Japan.

METHODS

CMC were defined as patients under the age of 20 years requiring medical care and devices. The patients were enrolled using the national health insurance claims data of three hospitals and two rehabilitation centers in Tottori Prefecture. The study period was divided into three periods: Period 1, 2007-2010; Period 2, 2011-2014; and Period 3, 2015-2018.

RESULTS

A total of 378 CMC were enrolled. The prevalence of CMC was 1.88 per 1000 population among subjects aged <20 years in 2018, and it increased by approximately 1.9 times during the study period. The number of CMC who presented with severe motor and intellectual disabilities did not change from Period 1 to Period 3. Meanwhile, the number of CMC who had relatively preserved motor and intellectual abilities increased from 58 to 98. The proportion of CMC who required respiratory management and oxygen therapy increased by 1.3 and 1.8 times, respectively. By contrast, the proportion of CMC who need tube feeding decreased significantly between periods 1 and 3 (P < 0.05).

CONCLUSIONS

The prevalence of CMC increased almost twice during the 12-year study period; however, the increase in the number of patients with relatively preserved motor and intellectual abilities was pronounced. This study showed that the need for medical care and devices differed based on the underlying disorders and severity of CMC; therefore, individualized medical, welfare, and administrative services and education about the various types of CMC must be provided.

The association of Trisomy 13 and 18 and hospital discharge outcomes among neonates in California: A retrospective cohort study

BACKGROUND

Despite Trisomy 13 and 18 being among the most fatal congenital anomalies, limited information exists about resource utilization and factors associated with length of stay (LOS) and total hospital charges (THC) for these anomalies.

METHODS

We studied data sets of the patient discharge data set from the California Office of Statewide Health Planning and Development from 2006 to 2010, to determine differences in resource utilization for survivors and non-survivors and identify the predictors of LOS and total hospital charges. Descriptive statistics were assessed for demographic and clinical characteristics. General linear regression models were used to identify predictors of LOS and THC.

RESULTS

Seventy-six Trisomy 13 and 115 Trisomy 18 patients were identified, for whom inpatient mortality was 27.6% and 20.9%, respectively. In patients with Trisomy 13, after adjusting for gender, ethnicity, advanced directive (DNR), insurance and co-morbidities on multivariate analysis, the provision of more than 96 h of mechanical ventilation was associated with significantly increased LOS (standard error, SE) by 18.0 ± 5.3 days and THC (SE) by $399,000 ± $85,000. In terms of insurance type, patients with private coverage had 10.8 ± 4.9 days more than patients with Medicaid. In patients with Trisomy 18, on multivariate analysis, after adjusting for gender, ethnicity, DNR, insurance and co-morbidities, more than 96 h of mechanical ventilation was associated with increased LOS (SE) by 36.8 ± 6.8 days and THC (SE) by $365,000 ± $59,000.

CONCLUSION

Understanding predictors that are associated with longer LOS and higher THC may be associated in hospital resource allocation for this vulnerable population of infants.

Survival and healthcare utilization of infants diagnosed with lethal congenital malformations

OBJECTIVE

We assessed survival, hospital length of stay (LOS), and costs of medical care for infants with lethal congenital malformations, and also examined the relationship between medical and surgical therapies and survival.

STUDY DESIGN

Retrospective cohort study including infants born 1998-2009 with lethal congenital malformations, identified using a longitudinally linked maternal/infant database.

RESULTS

The cohort included 786 infants: trisomy 18 (T18, n = 350), trisomy 13 (T13, n = 206), anencephaly (n = 125), bilateral renal agenesis (n = 53), thanatophoric dysplasia/achondrogenesis/lethal osteogenesis imperfecta (n = 38), and infants > 1 of the birth defects (n = 14). Compared to infants without birth defects, infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias had longer survival rates, higher inpatient medical costs, and longer LOS.

CONCLUSION

Care practices and survival have changed over time for infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias. This information will be useful for clinicians in counseling families and in shaping goals of care prenatally and postnatally.

Clinical features and practice patterns of gastroschisis: a retrospective analysis using a Japanese national inpatient database

PURPOSE

The number of infants with gastroschisis is increasing worldwide, but advances in neonatal intensive care and parenteral nutrition have reduced gastroschisis mortality. Recent clinical data on gastroschisis are often from Western nations. This study aimed to examine clinical features and practice patterns of gastroschisis in Japan.

METHODS

We examined treatment options, outcomes, and discharge status among inpatients with simple gastroschisis (SG) and complex gastroschisis (CG), 2010-2016, using a national inpatient database in Japan.

RESULTS

The 247 eligible patients (222 with SG) had average birth weight of 2102 g and average gestational age of 34 weeks; 30% had other congenital anomalies. Digestive anomalies were most common, followed by circulatory anomalies. In-hospital mortality was 8.1%. The median age at start of full enteral feeding was 30 days. The median length of stay was 46 days. There were no significant differences in outcomes except for length of stay, starting full enteral feeding and total hospitalization costs between the SG and CG groups. About 80% of patients were discharged to home without home medical care. The readmission rate was 28%.

CONCLUSION

This study's findings on the clinical characteristics and outcomes of gastroschisis are useful for the clinical management of gastroschisis.

Prenatal counseling and parental decision-making following a fetal diagnosis of trisomy 13 or 18

OBJECTIVES

To evaluate parental decisions following a prenatal diagnosis of trisomy 13 (T13) or trisomy 18 (T18), prenatal counseling received, and pregnancy outcomes.

STUDY DESIGN

Single-center, retrospective cohort study of families with a prenatal diagnosis of T13 or T18 from 2000 to 2016.

RESULTS

Out of 152 pregnancies, 55% were terminated. Twenty percent chose induction with palliative care, 20% chose expectant management, 2% chose full interventions, and 3% were lost to follow-up. Counseling was based on initial parental goals, but most women were given options besides termination. Women who chose expectant management had a live birth in 50% of the cases. Women who chose neonatal interventions had a live birth in 100% of the cases, but there were no long-term survivors.

CONCLUSIONS

The majority of women who continue their pregnancy after a fetal diagnosis of T13 or T18 desire expectant management with palliative care. A live birth can be expected at least half of the time.

Major anomalies and birth-weight influence NICU interventions and mortality in infants with trisomy 13 or 18

OBJECTIVE

To describe neonatal intensive care unit (NICU) medical interventions and NICU mortality by birth weight and major anomaly types for infants with trisomy 13 (T13) or 18 (T18).

STUDY DESIGN

Retrospective cohort analysis of infants with T13 or T18 from 2005 to 2012 in the Pediatrix Medical Group. We classified infants into three groups by associated anomaly type: neonatal surgical, non-neonatal surgical and minor. Outcomes were NICU medical interventions and mortality.

RESULTS

841 infants were included from 186 NICUs. NICU mortality varied widely by anomaly type and birth weight, from 70% of infants <1500 g with neonatal surgical anomalies to 31% of infants ⩾2500 g with minor anomalies. Infants ⩾1500 g without a neonatal surgical anomaly comprised 66% of infants admitted to the NICU; they had the lowest rates of NICU medical interventions and NICU mortality.

CONCLUSIONS

Risk stratification by anomaly type and birth weight may help provide more accurate family counseling for infants with T13 and T18.

Isolated tracheoesophageal fistula versus esophageal atresia - Early morbidity and short-term outcome. A single institution series

PURPOSE

We compared the postnatal course, morbidity and early results after repair for cases of isolated or "pure" TEF with those for cases of esophageal atresia (EA) with distal tracheoesophageal fistula (TEF).

METHODS

Twenty-four consecutive infants were divided into two groups: isolated TEF [TEF group] (n = 5) and EA with distal TEF [EA group] (n = 19).

RESULTS

A high rate of prematurity (29%) and major cardiac and other surgically-relevant malformations (0.8 vs. 0.7 per infant) was found in both groups. The median age at surgery was 8 days for the TEF group vs. 1 day for the EA group (p < 0.01). Most infants of both cohorts had stable acid-base and respiratory parameters at admission. Generally, tracheoscopy provided valuable information regarding the position of the TEF. Surgery for isolated TEF was performed via right cervicotomy in 4 cases and via thoracotomy in one. Postoperative thoracostomy tubes were inserted in 3 cases and one emergency gastrostomy was created for acute gastric overextension (exclusively in patients with EA). The duration of postoperative mechanical ventilation (49 vs. 113 h, p = 0.045) and the median length of stay in the pediatric surgery unit (10 vs. 20.5 days, p = 0.003) were shorter for the isolated TEF group. Four EA patients experienced severe events. Total mortality was 8% (0 out of 5 with TEF vs. 2 out of 19 with EA).

CONCLUSION

Developmental delay and a high rate of morbidity were found in both groups. More complex surgery increased perioperative morbidity in cases of EA. With early recognition of isolated TEF, a less complicated course can be expected in comparison with esophageal atresia.

Clinical features and survival in individuals with trisomy 18: A retrospective one-center study of 44 patients who received intensive care treatments

Trisomy 18 syndrome is a common autosomal aneuploidy chromosomal abnormality caused by the presence of extra chromosome 18 that leads to malformations of various parts of the body. In this study, we retrospectively investigated the effect of the medical progression and prognosis of 44 cases of trisomy 18, admitted to our neonatal intensive care unit between 1992 and 2013. The patients were divided into group A (n=20, 1992‑2002) and group B (n=24, 2003‑2012). Following delivery, karyotype, gender, gestational weeks, birth place, cesarean section, Apgar score and birth weight were analyzed using the Fisher's exact test, unpaired t‑test and Mann‑Whitney U test. Based on the statistical results, a comparison was made of the two groups and no significant differences were observed. Clinical data of major complications, mechanical ventilation, discharge from hospital and survival days were reviewed for the cases of trisomy 18. Of the 44 patients, 42 had cardiac anomaly, 16 had esophageal atresia, and 3 patients had brain anomaly. Ventilation treatment was performed in 29 cases (65.9%) and an increased percentage was identified in group B patients. The percentage survival was estimated using Kaplan‑Meier curves and the two groups were analyzed using the generalized Wilcoxon test. Improvement in life prognosis was observed in group B as compared to group A. The log‑rank test was used to assess survey periods of 180 days, 1 year, and the entire observation period. Although significant differences were observed for the prognosis of trisomy 18 at 180 days after birth, after 1 year and the entire survey period after birth, the significant differences were not confirmed. In conclusion, results of the present study provide information concerning genetic counseling for parents/guardians and life prognosis, prior to applying intensive management to newborns with trisomy 18.
