Externalized Rectal Duplication in a Newborn - A Differential Diagnosis of Meningomyelocele

Rectal duplication is a rare congenital anomaly with many clinical presentations, being mostly asymptomatic. Treatment consists of a surgical approach with a good prognosis. We are reporting a case of a full-term female newborn who presented with a mass externalized through the sacral region. The first diagnostic hypothesis was meningomyelocele, but the neurosurgeon verified peristalsis on examination with a surgical microscope. The pediatric surgery team proceeded with the investigation with barium enema, anal electrostimulation, biopsy, and pelvis MRI, confirming presacral rectal duplication. The patient underwent surgery for posterior sagittal surgical excision, with satisfactory evolution. Cases of rectal duplication are rare and we are unaware of reports of its exteriorization through the sacral region. Such presentation may mimic other diagnoses and should be included in the differential diagnosis of meningomyelocele.

Retrospective Analysis of Neonatal Surgery at Tottori University over the Past Ten Years

Background

In recent years, the number of neonatal surgeries has been on the rise despite the decline in the number of births, and we examined the actual trends and problems at Tottori University Hospital located in the Sanin region.

Methods

Medical records were retrospectively searched for patients who underwent major surgery during the neonatal period (within 30 days of age) at the Tottori University Hospital over the past 10 years (Jan. 2011 to Dec. 2020).

Results

Sixty-five cases were included. Early birth infants (< 37 gestational weeks) comprised 15 cases (23%) and low birth weight (< 2500 g) infants involved 27 cases (42%). In the latter half (2016-2020), early birth and low birth weight infants were significantly less than in the first half (2011-2015). The common diseases were anorectal malformation (14 cases), esophageal atresia (10), duodenal atresia (10), and diaphragmatic hernia (9). Prenatal diagnosis was obtained in 26 cases (40%), with high diagnostic rate obtained in duodenal atresia (100%), abdominal wall defect (100%), ileal atresia (75%), meconium peritonitis (67%), and diaphragmatic hernia (67%). Fifty-five cases (85%) were operated on within 7 days of age. Other major malformations were associated in 23 cases (35%). There were 6 deaths (9%), of which 3 cases were low birth weight infants with gastrointestinal perforation, 2 cases with severe chromosomal abnormalities (esophageal atresia, omphalocele), and 1 case with diaphragmatic hernia with severe pulmonary hypertension. Home medical care has been required with gastrostomy tube in 2 cases.

Conclusion

Neonatal surgery at Tottori University has been well performed as required with acceptable results along with the progression of other perinatal care. However, further investigation for improvements in premature delivery or organ hypoplasia may be required.

Serial lung mass volume ratios as prognostic indicators of neonatal respiratory morbidity in fetal pulmonary malformations

BACKGROUND

Several studies have shown that the congenital pulmonary airway malformation volume ratio is a useful prognosticator of neonatal outcome in prenatally diagnosed lung lesions. However, there remains a lack of consensus on which congenital pulmonary airway malformation volume ratio values have the best predictive value because of operator dependence, inherent changes in lung lesion size throughout gestation, and the widespread use of maternal steroids.

OBJECTIVE

This study sought to determine the association between serial congenital pulmonary airway malformation volume ratio measurements and neonatal outcomes among fetuses with lung malformations.

STUDY DESIGN

This was a retrospective cohort study of fetuses with a prenatally diagnosed lung malformation managed at 2 major fetal centers from January 2010 to December 2021. Prenatal variables, including prospectively measured congenital pulmonary airway malformation volume ratio measurements (initial, maximum, and final), were analyzed. The results were correlated with 3 outcome measures, namely surgical resection before 30 days of life, a need for supplemental O2 at birth, and endotracheal intubation at birth. Statistical analyses were performed using receiver operating characteristic curve analyses, Welch 2 sample t tests, and multivariable logistic regressions (P<.05).

RESULTS

There were 123 fetuses with isolated lung lesions identified. Eight (6.5%) had hydrops. The mean initial congenital pulmonary airway malformation volume ratio was 0.67±0.61 cm2 at 22.9±3.9 weeks' gestation. The mean maximum congenital pulmonary airway malformation volume ratio was 1.08 ± 0.94 cm2 at 27.0 ± 4.0 weeks' gestation. The mean final congenital pulmonary airway malformation volume ratio was 0.58±0.60 cm2 at 33.2±4.1 weeks' gestation. At a mean gestational age at delivery of 38.3±2.6 weeks, 15 (12.2%) underwent neonatal lung resection for symptomatic disease. In a multivariable regression, all 3 congenital pulmonary airway malformation volume ratio measurements showed a significant correlation with neonatal lung resection (P<.001). Optimal congenital pulmonary airway malformation volume ratio cutoffs were established based on an initial congenital pulmonary airway malformation volume ratio of ≥0.8 cm2, maximum congenital pulmonary airway malformation volume ratio of ≥1.5 cm2, and a final congenital pulmonary airway malformation volume ratio of ≥1.3 cm2 with associated areas under the curve of 0.89, 0.97, and 0.93, respectively. The final congenital pulmonary airway malformation volume ratio had the highest specificity for predicting surgical lung resection in the early postnatal period.

CONCLUSION

Measuring congenital pulmonary airway malformation volume ratios throughout pregnancy in fetuses with pulmonary malformations has clinical value for prenatal counseling and planning care transition after delivery. Fetuses with a final congenital pulmonary airway malformation volume ratio of more than 1.3 cm2 are likely to require neonatal surgery and therefore should be delivered at tertiary care centers with a neonatal intensive care unit and pediatric surgical expertise.

Rectal Atresia Treated Via a Transanal and Posterior Sagittal Approach: A Report of Two Cases

Rectal atresia is a rare cause of bowel obstruction in neonates with a normal-appearing anus. We present two different types of rectal atresia requiring different surgical management. Case one was a one-day-old term male with web-type rectal atresia diagnosed preoperatively with bedside obliteration of the web. Subsequent transanal web resection was performed. Case two was a one-day-old male born at 28 weeks weighing 980 g with significant cardiac defects including aortic atresia. The patient underwent initial colostomy creation and delayed rectal anastomosis via posterior sagittal anorectoplasty. We review the published literature, discuss the surgical strategy, and highlight the decision-making of diverting ostomy creation and approach of definitive anorectal anastomosis.

[Combination of esophageal atresia with proximal tracheoesophageal fistula and meconium peritonitis: a case report]

We report a patient with combination of esophageal atresia, proximal tracheoesophageal fistula and meconium peritonitis. These two rare disorders have different etiology, pathogenetic mechanisms and require different diagnostic manipulations and surgical treatments. The authors discuss the features of diagnosis and surgical treatment of this disease.

First Feed Type Is Associated With Birth/Lactating Parent's Own Milk Use During NICU Stay Among Infants Who Require Surgery

BACKGROUND

Early exclusive birth/lactating parent's own milk (B/LPOM) feeds have been associated with longer duration of B/LPOM use for infant feedings in healthy term and hospitalized preterm infants. This relationship has not been explored in infants undergoing neonatal surgery (surgical infants).

PURPOSE

To evaluate the relationship between early exclusive B/LPOM feeds and cumulative B/LPOM patterns during surgical infants' neonatal intensive care unit (NICU) hospitalization.

METHODS

A secondary cross-sectional analysis was performed using the electronic health record data of surgical infants admitted to a level IV NICU between January 2014 and March 2015. Multiple linear regression and Fisher's exact test were used to examine the associations between first NICU feed type and total percentage of diet composed of B/LPOM during NICU stay and continuation of any or exclusive B/LPOM feedings at NICU discharge, respectively.

RESULTS

The analysis included 59 infants who required surgery for gastrointestinal, cardiac, or multisystem defects or pregnancy-related complications. Receipt of B/LPOM as the first NICU feed was associated with higher percentage of B/LPOM feeds ( P < .001) throughout NICU stay, as well as continuation of any or exclusive B/LPOM feedings at NICU discharge ( P = .03).

IMPLICATIONS FOR PRACTICE

Early exclusive B/LPOM feeds may be an important predictor for continuation of any B/LPOM use throughout the NICU stay and at NICU discharge. Continued efforts to identify and address gaps in prenatal and postpartum lactation support for parents of surgical infants are needed.

IMPLICATIONS FOR RESEARCH

Powered studies are needed to corroborate these findings and to explore the potential impact of other factors on duration and exclusivity of B/LPOM use.

Sepsis Screening of Neonatal Abdominal Surgery and Its Outcomes

Aim

The aim of this study was to evaluate the early indicators of sepsis (sepsis screening) and their statistical correlation with sepsis in neonatal abdominal surgery.

Materials and Methods

A prospective observational study was performed on thirty consecutive neonate cases aged between 0 and 28 days with surgical abdomen at the Paediatric Surgery Department, ABVIMS and Dr. Ram Manohar Lohia Hospital, New Delhi. The study duration was 18 months. Septic screening was done in all neonates on day 0, 1, 3, 7, and 14 days of surgery with serum procalcitonin, C-reactive protein, total leukocyte count, immature/total neutrophil ratio, and microerythrocyte sedimentation rate. A septic screening-positive patient (three or more positive parameters out of five) was correlated with sepsis and analysis was done.

Results

A total of 30 neonates of abdominal surgical cases were included consequently, out of which 56.7% (n = 17) were male and 43.3% (n = 13) were female. Maximum cases were of congenital diaphragmatic hernia 20% (n = 6) and then anorectal malformation 16.7% (n = 5). About 70% of neonates were sepsis screening positive. Fifty percentage of neonates were diagnosed to have sepsis on the clinical or laboratory findings, so sensitivity and specificity of sepsis screening were 93.33% and 40%, respectively. There was total 30% mortality in this study.

Conclusion

Sepsis screening is an early marker of sepsis, which can be used to help in early detection of neonatal surgical sepsis and timely intervention that can lead to decrease mortality and morbidity in neonatal surgery.

Association of neutropenia at disease onset with severe surgical necrotizing enterocolitis and higher mortality: A retrospective study

Background

Neutrophils are among the earliest immune cells recruited to the site of an intestinal injury, but their predictive role in the progression of necrotizing enterocolitis (NEC) has not been fully elucidated. This study aimed to evaluate if a reduction in neutrophils at the onset of NEC is associated with severe surgical NEC and/or NEC-associated deaths.

Methods

This is a retrospective cohort study in which neonates underwent surgery due to NEC during 2015-2020. The data on absolute neutrophil count (ANC), before and at the onset of NEC, were collected from the complete blood count results. The primary exposure was the difference in absolute neutrophil count (ΔANC) at NEC onset. The primary outcome was severe surgical NEC, defined as the residual small bowel length after intestinal resection of <30 cm.

Results

A total of 157 neonates were included in this study, of which 53 were diagnosed with severe surgical NEC. A decrease in ANC at the onset of NEC was associated with an increased probability of severe surgical NEC (crude odds ratio [OR] 1.248, 95% CI 1.107-1.407; P = 0.000). ΔANC (area under the curve [AUC] 0.729, 95% CI 0.653-0.797; P < 0.001] was a good predictor for severe surgical NEC. The addition of platelets to ΔANC at NEC onset (AUC 0.738, 95% CI 0.662-0.808; P < 0.001) resulted in a higher AUC and specificity for severe surgical NEC prediction than ΔANC alone. A reduction in the neutrophil count at NEC onset (ΔANC > 0) was associated with adverse outcomes (hazard ratio [HR] 3.48, 95% CI 1.64-7.36) and a lower survival probability (χ² 10.63; P < 0.001).

Conclusion

A reduction in the ANC at the onset of NEC was associated with severe surgical NEC and higher mortality. The addition of platelets to ΔANC at NEC onset resulted in a higher predictive value of severe surgical NEC. This study may provide a new insight into the bedside evaluation of NEC by analyzing data from the day of NEC onset.

Case reports of large and symptomatic abdominal tumors in newborns: Pitfalls, difficulties in management, and surgical decision making

BACKGROUND

Large and rapidly growing abdominal tumors may result in fatal outcomes in newborns. In some cases, a rapidly worsening clinical condition requires surgical decision-making despite the absence of a precise histological diagnosis. In these situations, there is neither a guide nor consensus.

CASE

We highlight our experience with five patients with large abdominal tumors and assess the available literature for the best possible management of a rare condition.

CONCLUSION

In these cases, laparostomy should be considered as a life-saving procedure. If the liver is involved and coagulopathy is present, prognosis is often compromised.

Outcome of esophageal atresia: inborn versus outborn patients

Esophageal atresia (EA) is a rare congenital disease which is usually not of the detected prenatally. Due to the lack of prenatal diagnosis, some newborns with EA are born outside of specialized centers. Nevertheless, centralized care of EA has been proposed, even if a clear volume-outcome association in EA management remains unconfirmed. Furthermore, whether outcomes differ between outborn and inborn patients with EA has not been systematically investigated. Therefore, this single-center, retrospective study aimed to investigate EA management and outcomes with a special focus on inborn versus outborn patients. The following data were extracted from the medical records of infants with EA from 2009 to 2019: EA type, associated anomalies, complications, and long-term outcome. Patients were allocated into inborn and outborn groups. Altogether, 57 patients were included. Five patients were excluded (referral before surgery, loss of data, death before surgery [n = 1], and incorrect diagnosis [diverticulum, n = 1]). Among all patients, the overall survival rate was 96%, with no mortalities among outborn patients. The overall hospitalization period was shorter for outborn patients. The median follow-up durations were 3.8 years and 3.2 years for inborn and outborn patients, respectively. Overall, 15% of patients underwent delayed primary anastomosis (long-gap atresia [n = 4] and other reasons [n = 4]). Early complications included three anastomotic leakages and one post-operative fistula; 28% of patients developed strictures, which required dilatation, and 38% of patients showed relevant gastroesophageal reflux, which required fundoplication, without any differences between the groups. The two groups had comparable low mortality and expected high morbidity with no significant differences in outcome. The outborn group showed nonsignificant trends toward lower morbidity and shorter hospitalization periods, which might be explained by the overall better clinical status.

Impact of surgery and anesthesia during early brain development: A perfect storm

Neonatal surgery and concomitant anesthesia coincide with a timeframe of rapid brain development. The speed and complexity of early brain development superimposed on immature regulatory mechanisms that include incomplete cerebral autoregulation, insufficient free radical scavenging and an immature immune response puts the brain at risk. Brain injury may have long-term consequences for multiple functional domains including cognition, learning skills, and behavior. Neurodevelopmental follow-up studies have noted mild-to-moderate deficits in children who underwent major neonatal surgery and related anesthesia. The present review evaluates neonatal surgery against the background of neurobiological processes that unfold at a pace unparalleled by any other period of human brain development. First, a structured summary of early brain development is provided in order to establish theoretical groundwork. Next, literature on brain injury and neurodevelopmental outcome after neonatal surgery is discussed. Special attention is given to recent findings of structural brain damage reported after neonatal surgery. Notably, high-quality imaging data acquired before surgery are currently lacking. Third, mechanisms of injury are interrogated taking the perspective of early brain development into account. We propose a novel disease model that constitutes a triad of inflammation, vascular immaturity, and neurotoxicity of prolonged exposure to anesthetic drugs. With each of these components exacerbating the other, this amalgam incites the perfect storm, resulting in brain injury. When examining the brain, it seems intuitive to distinguish between neonates (i.e., <60 postconceptional weeks) and more mature infants, multiple and/or prolonged anesthesia exposure and single, short surgery. This review culminates in an outline of anesthetic considerations and future directions that we believe will help move the field forward.

Predicting Factors of Protracted Intestinal Failure in Children with Gastroschisis

OBJECTIVE

To identify prenatal and neonatal predictors of short bowel syndrome-related intestinal failure (SBS-IF) in gastroschisis.

STUDY DESIGN

This retrospective study included all patients with gastroschisis born between 2000 and 2017 who were enrolled in our home parenteral nutrition program, and all patients with gastroschisis born in our institution who survived 2 weeks, during the same time period. Prenatal ultrasound features, neonatal status, anatomic features, oral feeding, and parenteral nutrition dependency were analyzed.

RESULTS

Among 180 patients, 35 required long-term parenteral nutrition (SBS-IF group) and 145 acquired full oral feeding within 6 months (oral feeding group). The mean follow-up was 7.9 years (IQR, 1.6-17.5 years) and 5.0 years (IQR, 0.1-18.2 years), respectively. Both bowel matting (OR, 14.23; 1.07-16.7; P = .039) and secondarily diagnosed atresia or stenosis (OR, 17.78; 3.13-100.98; P = .001) were independent postnatal predictors of SBS-IF. Eighteen children (51% of the SBS-IF group) were still dependent on artificial nutrition at the last follow-up. patients with SBS-IF who achieved full oral feeding had a median residual small-bowel length of 74 cm (IQR, 51-160 cm) vs 44 cm (IQR, 10-105 cm) for those still dependent on artificial nutrition (P = .02). An initial residual small bowel length of more than 50 cm was the best predictive cut-off for nutritional autonomy, with a sensitivity of 67% and a specificity of 100%.

CONCLUSIONS

Bowel matting, complex gastroschisis, and secondary intestinal obstruction were associated with SBS-IF in gastroschisis. For patients with SBS-IF, a small bowel length of more than 50 cm was predictive of secondary nutritional autonomy.

Neonatal medical trainee doctors' perceptions and parents' self-reported needs and stressors in a surgical neonatal intensive care unit: An individualised approach

AIM

As more infants survive surgery in the newborn period for major congenital anomalies, the focus has shifted to the quality of care for parents as well as infants. In contemporary neonatal intensive care units (NICUs), doctors are encouraged to practice family-centred care and partner with parents in their infant's care. This study explored doctors' perceptions and parents' self-reported needs and stressors in a surgical NICU.

METHODS

From January 2014 to September 2015, parents of infants admitted for general surgery for a major congenital anomaly who were present in the NICU between 48 and 72 h of admission and doctors caring for their infant at the time of data collection were invited to participate. Matched data were provided using the Neonatal Family Needs Inventory and the Parental Stressor Scale:NICU.

RESULTS

Matched data for 12 doctor-parent dyads showed that doctors (neonatal medical trainees) consistently under-rated the importance of parents' needs and identified fewer of mothers' than fathers' most important needs. Doctors also consistently under-rated parents' stressors. They perceived few of fathers', but all of mothers', greatest stressors. Thematic analysis revealed four themes: infant pain management; parental autonomy; empathy; and communicating reassurance and education to parents.

CONCLUSION

The findings suggest incongruences between doctors' perceptions and parents' self-reported needs and stressors. While there is hesitation in making recommendations with this sample size, the findings highlight issues that may inform further research and contribute to a dialogue regarding the role of doctors in family-centred relationship-based models of care in the NICU.

Santulli Procedure Revisited in Congenital Intestinal Malformations and Postnatal Intestinal Injuries: Preliminary Report of Experience

In our experience, the Santulli procedure (SP) can improve bowel recovery in congenital intestinal malformations, necrotizing enterocolitis (NEC), and bowel perforation. All cases managed at our institution using SP between 2012 and 2017 were included in this study. Forty-one patients underwent SP (median age: 39 (0-335) days, median weight: 2987 (1400-8100) g) for intestinal atresia (51%, two gastroschisis), NEC (29%), midgut volvulus (10%), Hirschsprung's disease (5%), or bowel perforation (5%), with at least one intestinal suture below the Santulli in 10% of cases. The SP was performed as a primary procedure (57%) or as a double-ileostomy reversal. Anal-stool passing occurred within a median of 9 (2-36) days for 95% of patients, regardless of the diversion level or the underlying disease. All three patients requiring repeated surgery for Santulli dysfunction had presented with stoma prolapse (p < 0.01). Stoma closure was performed after a median of 45 (14-270) days allowing efficient transit after a median of 2 (1-6) days. After a median follow-up of 2.9 (0.7-7.2) years, two patients died (cardiopathy and brain hemorrhage), full oral intake had been achieved in 90% of patients, and all survivors had normal bowel movement. Whether used as primary or secondary surgery, the SP allows rapid recovery of intestinal motility and function.

Our Neonatal Surgery Experiences in Somalia

Purpose

The aim of this study is to report surgical outcomes of the neonates who have undergone various surgical procedures.

Materials and Methods

In this retrospective study, 39 neonates who have undergone a surgical procedure in Mogadishu Somalia Turkey Recep Tayyip Erdoğan Training and Research Hospital, between October 2018 and March 2019 were included. Data regarding age, gender, diagnosis, surgical procedure, length of hospital stay, mortality, and cause of mortality were recorded.

Results

Of 39 neonates, 12 were female (30.7%) and 27 were male (69.3%). The mean age of the neonates at admission was 7.7 ± 7.6 days (1-30 days) days. The most common diagnoses were anal atresia (n = 12, 30.8%), esophageal atresia (n = 9, 23.1%), and pyloric stenosis (n = 5, 12.8%). The most common surgical procedures were colostomy creation (n = 10, 25.6%), esophageal anastomosis (n = 9, 20.5%), primary closure of anterior abdominal wall defects including bladder exstrophy (n = 6, 15.4%), and pyloromyotomy (n = 5, 12.8%). Mortality rate was 17.9%, and mortality causes were sepsis (n = 4, 57.1%) and congenital heart disease (n = 3, 42.9%). Neonates with the highest mortality by underlying primary surgical diagnosis were esophageal atresia (n=4, 57.1%).

Conclusion

The mortality rate from the surgical procedures of the neonates in Somalia is extremely high when compared with the developed countries. Employment of experienced pediatric surgeons and well-trained nurses, strict attention to the sanitary measures and shortening the time from birth to presentation might improve the surgical outcomes of the neonates in Somalia.

The Financial Burden of Surgery for Congenital Malformations-The Austrian Perspective

Neonatal “surgical” malformations are associated with higher costs than major “non-surgical” birth defects. We aimed to analyze the financial burden on the Austrian health system of five congenital malformations requiring timely postnatal surgery. The database of the Austrian National Public Health Institute for the period from 2002 to 2014 was reviewed. Diagnosis-related group (DRG) points assigned to hospital admissions containing five congenital malformations coded as principal diagnosis (esophageal atresia, duodenal atresia, congenital diaphragmatic hernia, gastroschisis, and omphalocele) were collected and compared to all hospitalizations for other reasons. Out of 3,518,625 total hospitalizations, there were 1664 admissions of patients with the selected malformations. The annual mean number was 128 (SD 17, range 110–175). The mean cost of the congenital malformations per hospital admission expressed in DRG points was 26,588 (range 0–465,772, SD 40,702) and was significantly higher compared to the other hospitalizations (n = 3,516,961; mean DRG 2194, range 0–834,997; SD 6161; p < 0.05). Surgical conditions requiring timely postnatal surgery place a significant financial burden on the healthcare system. The creation of a dedicated national register could allow for better planning of resource allocation, for improving the outcome of affected children, and for optimizing costs.

The Ross/Ross-Konno procedure in infancy is a safe and durable solution for aortic stenosis

OBJECTIVE

The objective of this study was to characterize early and midterm outcomes after the Ross/Ross-Konno procedure performed in infancy for severe aortic valve disease.

METHODS

Between January 1995 and December 2018, 35 infants younger than 1 year (13 neonates) underwent a Ross/Ross-Konno procedure. Patients were followed up to a median of 4.1 years (interquartile range [IQR], 2.6-9.5). Primary outcome measures were survival, early morbidity, freedom from reintervention and long-term functional and echocardiographic status.

RESULTS

Median age at operation was 49 days (IQR, 17-135) and weight was 4 kg (IQR, 3.4-5.2). Thirty-one (89%) had undergone a previous procedure, including balloon valvuloplasty in 26 (74%). Thirty (86%) required annular enlargement (Konno incision). Five required concomitant aortic arch surgery (2 neonates, 3 infants). There were no early deaths, and 1 late death at 18 months. Freedom from reoperation was 85% (95% confidence interval [CI], 68%-93%) at 1 year, 76% (95% CI, 54%-88%) at 5 years, and 62% (95% CI, 36%-79%) at 10 years. One modified Konno was performed at 5 years after a Ross in infancy. Ten right ventricle to pulmonary artery conduits have required reintervention (2 percutaneous pulmonary valve implantations). One child required a permanent pacemaker for complete heart block. At latest follow-up, 32 (94%) of 34 survivors were asymptomatic. There was no significant change in neoaortic Z-scores between 6 weeks and latest follow-up.

CONCLUSIONS

The neonatal and infant Ross/Ross-Konno procedure can be performed with low mortality and achieves a stable left ventricular outflow tract. Significant early morbidity reflects the preoperative condition of the patients but definitive surgery of this type can be considered as a primary approach.

Laparoscopic Management of Congenital Intestinal Obstruction: Duodenal Atresia and Small Bowel Atresia

Background: Congenital intestinal obstruction occurs in ∼1:2000 live births. Congenital duodenal atresia and duodenal stenosis are frequent causes of intestinal obstruction and occur in 1 per 5000-10,000 live births. Today, duodeno-duodeno anastomosis is still the treatment of choice, and it can be performed safely by minimally invasive surgery, although duodenojejunal anastomosis is surgically simpler and has equal results. Jejunum-ileal atresia or stenosis is a major cause of neonatal intestinal obstruction; its prevalence is 1:330-1:1500 live births. Nowadays, the ability of laparoscopic assisted identification of the atresia and repair by only exteriorization of the small bowel through the umbilicus makes this technique safe and feasible in almost every new born. Methods: This article will describe the operative technique of laparoscopic management of congenital duodenal and small bowel obstruction. Results: For congenital duodenal atresia patients, mortality rate is less than 5% and the majority are secondary to associated comorbidities. There is a low rate of anastomotic leaks, anastomotic stricture, delayed gastric emptying, and bacterial overgrowth. For small bowel atresia patients, complications include anastomotic leak, adhesions, small bowel obstruction, and short bowel syndrome in less than 5% of the patients. The rate of re-operations due to small bowel obstruction in laparoscopic assisted repair patients is less compared with laparotomy patients. Conclusions: Minimally invasive surgery for duodenal and small bowel atresia is safe and feasible and reduces the complications of open surgical procedures.

WeChat-assisted health education improves care ability, reduces care burden and improves quality of life of parents of infants after enterostomy

AIM

The purpose of this study was to explore the effect of implementing WeChat-assisted health education for parents of infants after enterostomy.

METHODS

This study retrospectively analysed the clinical data of 106 infants after enterostomy whose parents received WeChat-assisted health education in our hospital from June 2017 to June 2019. The clinical data of 92 infants after enterostomy whose parents received traditional health education in our hospital from May 2015 to May 2017 were selected as the control group.

RESULTS

The care ability of the WeChat health education group was significantly better than that of the traditional health education group (P < 0.05). The care burden of the WeChat health education group was significantly lower than that of the traditional health education group (P < 0.05). The results of the WHOQOL-BREF showed that the quality of life for WeChat health education group was significantly higher than that for the traditional health education group (P < 0.05). The incidence of complications, including mucosal oedema, allergic dermatitis, faecal dermatitis and avulsion injury, in the WeChat health education group was significantly lower than that in the traditional health education group.

CONCLUSION

The implementation of WeChat-assisted health education for parents of infants after enterostomy can effectively improve parents' care ability, reduce parents' care burden, improve parents' quality of life and reduce the incidence of complications in patients.

Operating Within the Neonatal Intensive Care Unit: A Retrospective Analysis From a Tertiary Care Center

Background

Despite ongoing advances in the field of neonatology, the survival outcomes among critically ill preterm surgical neonates remain unfavorable. Intrahospital transport is one of the major risk factors associated with early mortality (within 30 days) in these newborns. To overcome this, the approach of performing bedside surgeries is being followed. We aim to assess the safety and feasibility of performing bedside neonatal surgeries by analyzing our archives.

Methods

The study focused on retrospective evaluation of all the newborns who have undergone surgical procedures in the neonatal intensive care unit (NICU) at our center from August 2015 through February 2021. Newborns were operated within the NICU if they had very low birth weight or other risk factors making their transport to the operation room risky. The outcomes of surgeries were assessed in terms of postoperative complications, one-month survival, and overall survival.

Results

Thirteen children (M:F=9:4) underwent twenty-two surgical procedures. The median (range) gestational age and birth weight of our cohort were 30 (26-36) weeks and 1200 (500-2860) grams, respectively. One-month and overall survival rates in our cohort were 84% (11/13) and 77% (10/13), respectively. No major postoperative complications were observed. The requirement of multiple inotropes and/or high-frequency oscillatory ventilation (HFOV) was the only factor having a significant association with unfavorable survival outcomes.

Conclusions

Bedside surgery is a safe and feasible alternative to surgeries within the operation room for at-risk newborns. In the present study, the requirement of multiple inotropes and/or HFOV was the only factor significantly associated with early mortality.

Neurodevelopmental outcome in infants with esophageal atresia: risk factors in the first year of life

Data on neurodevelopmental outcomes of infants born with esophageal atresia (EA) are still scarce and controversial. The aims of our study were to evaluate motor and cognitive development during the first year of life, in patients operated on of EA and to investigate potential risk factors for motor and cognitive development both at 6 and 12 months. This is an observational prospective longitudinal study in a selected cohort of type C and D EA infants enrolled in our follow-up program from 2009 to 2017. In order to exclude possible confounding factors, the following exclusion criteria were applied: (i) gestational age ≤ 32 weeks and/or birth weight ≤ 1500 g; (ii) genetic syndrome or chromosomal anomaly known to be associated with neurodevelopmental delay; (iii) neurologic disease; (iv) esophageal gap ≥three vertebral bodies. Patients were evaluated at 6 and 12 months of life (corrected age for infants with a gestational age of 32-37 weeks) with the Bayley Scales of Infant and Toddler Development-3rd Edition. In our selected cohort of EA infants, 82 were evaluated at 6 months and 59 were reevaluated at 12 months. Both Motor and Cognitive average scores were within the norm at both time points. However, we report increased number of infants with motor delay with time: 14% at 6 months and 24% at 12 months. Multiple regression analysis for Motor scores at 6 [F(4,74) = 4.363, P = 0.003] and 12 months [F(6,50) = 2.634, P = 0.027] identified (i) low birth weight, (ii) longer hospital stay and (iii) weight < fifth percentile at 1 year as risk factors. Interestingly, average Cognitive scores also increased with time from 85.2% at 6 months and 96.6% at 12 months. Multiple regression models explaining variance of Cognitive scores at 6 [F(4, 73) = 2.458, P = 0.053] and 12 months [F(6, 49) = 1.232, P = 0.306] were nonsignificant. Our selected cohort of EA patients shows, on the average, Motor and Cognitive scores within the norm both at 6 and 12 months. Nevertheless, the percentage of infants with Motor scores below the average increases regardless gestational age. None of clinical and sociodemographic variables taken into consideration was able to predict cognitive development both at 6 and 12 months whereas risk factors for Motor development change during the first year of life. Healthcare providers should pay particular attention to patients with low birth weight, longer hospital stays and weight under fifth percentile at 1 year. Future studies should include long-term outcomes to reveal possible catch up in motor development and/or possible findings in Cognitive scores.

Invasive Candida Infections in Neonates after Major Surgery: Current Evidence and New Directions

Infections represent a serious health problem in neonates. Invasive Candida infections (ICIs) are still a leading cause of mortality and morbidity in neonatal intensive care units (NICUs). Infants hospitalized in NICUs are at high risk of ICIs, because of several risk factors: broad spectrum antibiotic treatments, central catheters and other invasive devices, fungal colonization, and impaired immune responses. In this review we summarize 19 published studies which provide the prevalence of previous surgery in neonates with invasive Candida infections. We also provide an overview of risk factors for ICIs after major surgery, fungal colonization, and innate defense mechanisms against fungi, as well as the roles of different Candida spp., the epidemiology and costs of ICIs, diagnosis of ICIs, and antifungal prophylaxis and treatment.

Association of clinical factors with postoperative complications of esophageal atresia

BACKGROUND

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) remains one of the most common gastrointestinal neonatal malformations. Even though postoperative management is standardized, it differs between hospitals and disease-associated clinical factors that may play a role in outcome have not yet been assessed in detail.

METHODS

In this monocentric retrospective study, data of 43 patients with EA between 2010 and 2018 were analyzed. Analysis includes assessment of the clinical background, surgical technique, postoperative management including application of continuous muscle relaxation (CMR), influence of coagulation parameters such as factor XIII and incidence of complications.

RESULTS

21 patients (49%) were preterm infants with birth weights between 490 and 2840 g (median 1893 g). Only 35% (n = 15) presented without any concomitant malformations. Within the entire study population, representing Vogt II, IIIb and IIIc, we observed an association between the development of a postoperative pneumothorax and anastomotic failure (AF) (p = 0.0013). Furthermore, pneumothorax was associated with anastomotic stenosis (AS) in Vogt IIIb patients (p = 0.0129). CMR (applied since March 2017 in 7 patients in an attempt to prevent anastomotic problems due to high complication rates) and coagulation factor XIII did not significantly correlate with postoperative outcome.

CONCLUSION

Appearance of pneumothorax was correlated with postoperative complications. These children should be monitored carefully in closer scheduled gastroenterological follow-up esophago-gastro-duodenoscopies. CMR and factor XIII substitution did not reduce anastomotic leakage but should be tested within an enlarged study population.

Epidemiology and outcomes of gastroschisis in Tasmania

AIM

To describe the epidemiology and outcomes of gastroschisis in Tasmania.

METHODS

A retrospective analysis of all pregnancies complicated by gastroschisis in Tasmania from 1996 to 2015 was undertaken (epidemiology cohort), and the presentation, surgical management and outcomes (surgery cohort) were reviewed for the period between September 1990 and July 2015.

RESULTS

Gastroschisis was detected in 58 pregnancies during the 20-year epidemiology cohort period, giving an incidence of 4.4 per 10 000 live births for the 20-year period. Two of the four stillbirths occurred after 36 weeks' gestation. Of the 65 babies with gastroschisis treated at the Royal Hobart Hospital, 51 had a staged surgical repair (silo in 47, stoma formation in 4), and 14 had a primary closure. Staged repair was associated with a significantly longer duration of ventilation and stay in the neonatal intensive care unit. There were six post-natal deaths, all born in the first epoch. Death was significantly associated with the condition of the intestine at delivery (P = 0.02). There were no deaths in babies with simple gastroschisis. Complex gastroschisis was significantly associated with longer duration of total parenteral nutrition (P = 0.0002) and longer stay in hospital (P = 0.03).

CONCLUSIONS

The incidence of gastroschisis in Tasmania is similar to that reported in other Australian regions and has not increased over the 20-year period of study. The high risk of stillbirth, and the significant association between mortality and the condition of the intestine at birth necessitates close fetal surveillance. Complex gastroschisis imposes a significant burden on hospital resources.

Surgery in the Neonatal Intensive Care Unit in Indian Scenario: Should It be "The New State of the Art" or Just "The Need of the Hour"?

Introduction:

Critically ill surgical neonates are physiologically challenged and delicately poised on ventilator and inotropic support systems. They experience significant stress in the event of surgery. Shifting them poise further addition to this stress. We here share our experience of operating such surgical neonates for certain conditions in the neonatal intensive care unit (NICU).

Methods:

We retrospectively analyzed the data of operated patients in the NICU. We collected the demographic data, diagnosis, and preoperative stability of the patient, ventilator and inotropic requirements, need for extra anesthetic drugs, procedures performed, complications, and outcome. Operations were performed at bedside in the NICU in critically ill, unstable neonates who needed emergency surgery, neonates of very low birth weight (<1000 g), and neonates on special equipment such as high-frequency ventilators. We excluded minor routine procedures such as drain placement, central line placement, ventricular taps, incision and drainage, and intercostal drainage procedures.

Results:

We performed seven surgical procedures in the NICU. These included bowel resections and stoma creation, fistula ligation, lung biopsies, and ventricular reservoir placement. Gestational age ranged between 24 and 34 weeks (mean, 28 weeks). Birth weights ranged between 800 and 2500 g (mean, 1357 g). Age at surgery was between 2 and 18 days (mean, 10.2 days). All our patients were on inotropic support and were intubated and mechanically ventilated.

Conclusion:

Doing surgery for critically ill neonates in the NICU definitely has a place. It was the need of the hour based on the condition of the neonates; however, we feel that neonatal surgery in the NICU should be the norm as it can improve survival. Surgery in the NICU can give a fighting chance to these patients; however, operation theaters in the NICU would be an ideal setting.

Innovative, Stabilizing Self-Expandable Patch for Easier and Safer Thoracoscopic Repair of Congenital Diaphragmatic Hernia

Introduction: Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has become a popular approach and several benefits have been published. Patch closure requires demanding thoracoscopic skills and therefore primary closure with tight sutures is often pursued, which increases the risk of recurrence. The purpose of this study was to create and assess the performance of a new technique for thoracoscopic repair of CDH, which facilitates the surgical procedure. Materials and Methods: An innovative system for thoracoscopic repair of CDH with a novel patch was developed. The patch is self-expandable and offers a traction suture for stabilization, isolating and protecting the viscera. Its performance was assessed and compared with a conventional patch in an inanimate model of the disease through a quantitative and qualitative multivariate analysis. Results: Nine cases of CDH were repaired with each patch. The duration of the procedure was shorter (P < .05) and the level of difficulty was reported to be lower (P < .001) when using the self-expandable patch (SeP). The number of good quality knots was higher and adverse events were less common with this new technique. Conclusions: The stabilizing SeP offers safe and ergonomic performance for thoracoscopic CDH repair, facilitating the surgical technique. The main advantage is that it keeps the viscera isolated into the abdomen while offering a flap on the thoracic side for suturing in a practical manner, minimizing the risk of visceral injury and saving surgical time.

Giant lymphatic malformation causing abdominal compartment syndrome in a neonate: a rare surgical emergency

Abdominal lymphatic malformations in neonates require sophisticated management. In symptomatic cases, acute complications may necessitate immediate surgery. We present the case of a giant abdominal lymphatic malformation diagnosed in the 18th gestational week. Sonographic concerns about intestinal hypoperfusion in the 33rd week of gestation indicated caesarean section. Postnatal imaging confirmed a macrocystic lymphatic malformation occupying almost the complete abdominal cavity; the intestinal perfusion was normal. Clinical deterioration on Day 13 of life required laparotomy. Intraoperatively, the lymphatic mass was located in the ileocecal mesentery. Two major cysts showed recent hemorrhage explaining the onset of abdominal compartment syndrome. The malformation was completely removed. An ileocecal resection with an ileocolic anastomosis was performed. The postoperative course was uneventful. In neonates with abdominal lymphatic malformations, an onset of abdominal compartment syndrome requires surgical exploration. If feasible, the complete removal of the lesion represents a curative option.

'They don't know themselves, so how can they tell us?': parents navigating uncertainty at the frontiers of neonatal surgery

When a baby is diagnosed with a condition needing surgery they, and their family, start down an uncertain and unknown path. Living with uncertainty underpins every stage of the journey from hospital to home. These journeys span the highly technical to the mundane. They are likely to involve, at crucial points, medicalised and specialised neonatal and surgical care in paediatric centres of excellence where parents are mere spectators. Yet ultimately parents are able to take their baby home, confident experts in their daily care. Drawing on narrative interviews with 42 UK parents whose baby underwent neonatal surgery, this paper explores how parents navigate this uncertainty through acquiring experiential and lay knowledge and developing expertise in their baby's condition and treatment options. These conditions are rare. Building on sociological understandings of the work of chronic illness, as well as more recent work on newborn screening, sharing information online and examinations of experiential knowledge, we explore lay knowledge and expertise as it intersects with biomedical and surgical frontiers. We demonstrate how the development of expertise is an emergent, three-stage process supported by both biomedical and lay knowledge and elucidate this process of knowledge-building as a scaffold through which to manage uncertainty.

Is Fetal Endoscopic Tracheal Occlusion (FETO) a Predisposing Factor for Acid Gastro-Esophageal Reflux in Infants With Congenital Diaphragmatic Hernia?

Introduction: Various anatomical defects predispose patients with congenital diaphragmatic hernia (CDH) to develop gastroesophageal reflux disease (GERD). The fetal endoscopic tracheal occlusion (FETO) has increased the survival of patients with severe CDHs. The aim of this study was to study GERD in patients who underwent FETO. Materials and Methods: We included patients with CDH treated with or without FETO ("FETO" and "no-FETO" group, respectively) from 2013 to 2016. Data on gestational age (GA), birth weight (BW), initial observed/expected lung to head ratio (O/E LHR), final O/E LHR, duration of ventilation and hospitalization, maximal tracheal diameter, and pulmonary volume were collected. All patients underwent pH-metry after 1 year of life, and the results were compared between groups and correlated to risk factors. Results: Thirty-two patients were included in the study: 10 FETO and 22 no-FETO. No significant differences were observed in the pH-metric results of the two groups. No correlation was found between GA, BW, initial O/E LHR, maximal tracheal diameter, pulmonary volume, and pH-metric results. pH-metric results were correlated with the total duration of ventilation (R = 0.5, p = 0.003) and of hospitalization (R = 0.54, p = 0.001). Gastric herniation is associated with the worse pH-metric result. Conclusions: The FETO procedure does not seem to represent an independent risk factor for GERD. However, patients with the most severe CDH have the worst GERD.

Impact of nutrition in the treatment of congenital diaphragmatic hernia

BACKGROUND

The optimum enteral (EN) and parenteral nutrition (PN) regimens during acute management of congenital diaphragmatic hernia (CDH) remain unclear. We examined the effects of EN and PN on weight gain in CDH patients.

METHODS

A multicenter retrospective cohort study of neonates with CDH (born 2006-2010; n = 105) who survived to discharge was conducted. Patients were divided as receiving PN ≥ or <50 kcal/kg/day at 1 week of age, and EN ≥ or <60 kcal/kg/day at 2 weeks of age. Changes in bodyweight at 30, 60, and 90 days of age were compared.

RESULTS

The higher EN group (n = 39) had greater mean weight gain than the lower EN group (n = 66; 90 days: 2,501 g, 95% CI: 2,294-2,710 g vs 1,706 g, 95% CI: 1,553-1,861 g; P <0.001). When patients received lower EN, the higher PN group (n = 24) had greater mean weight gain than the lower PN group (n = 42; 90 days: 1,768 g, 95% CI: 1,574-1,961 g vs 1,411 g, 95% CI: 1,264-1,558 g; P = 0.004).

CONCLUSION

The amount of EN in the acute phase of CDH management is essential for weight gain during infancy. When patients are intolerant to adequate EN, supportive PN is also essential.

Needs of parents in a surgical neonatal intensive care unit

AIM

While there is evidence of parental needs in the neonatal intensive care unit (NICU), parents of newborns admitted for general surgery are an under-researched population. This study aimed to identify needs in parents of newborns admitted to the NICU for general surgery and whether health-care professionals meet these needs.

METHODS

This was a prospective cohort study of 111 parents (57% mothers) of newborns admitted to a surgical NICU for general surgery in Australia from January 2014 to September 2015. Parents completed the Neonatal Family Needs Inventory (NFNI), comprising 56 items in five subscales (Support, Comfort, Information, Proximity, Assurance) at admission and discharge, as well as the Social Desirability Scale (SDS). Data were analysed using parametric and non-parametric techniques.

RESULTS

At both admission and discharge, parents rated Assurance (M = 3.8, standard deviation (SD) = 0.24) needs as the most important, followed by Proximity (M = 3.6, SD = 0.32) and Information (M = 3.5, SD = 0.38). Mothers rated Assurance significantly more important than fathers (P < 0.02). Overall, parents' most important needs were having questions answered honestly (M = 3.96, SD = 0.19), seeing their infant frequently and knowing about the medical treatment (both M = 3.95, SD = 0.23). The 10 most important needs were met for more than 96% of parents, with no evidence of response bias.

CONCLUSIONS

Reassurance is a priority need for parents in the surgical NICU. Mothers' and fathers' needs may be best met by practices based on family-centred, individualised care principles.

Risk Factors for Surgical Site Infection in Neonates: A Systematic Review of the Literature and Meta-Analysis

Purpose: Surgical site infections (SSI) contribute to postoperative morbidity and mortality in children. Our aim was to evaluate the prevalence and identify risk factors for SSI in neonates. Methods: Using a defined strategy, three investigators searched articles on neonatal SSI published since 2000. Studies on neonates and/or patients admitted to neonatal intensive care unit following cervical/thoracic/abdominal surgery were included. Risk factors were identified from comparative studies. Meta-analysis was conducted according to PRISMA guidelines using RevMan 5.3. Data are (mean ± SD) prevalence. Results: Systematic review-of 885 abstracts screened, 48 studies (27,760 neonates) were included. The incidence of SSI was 5.6% (1,564 patients). SSI was more frequent in males (61.8%), premature babies (77.4%), and following gastrointestinal surgery (95.4%). Meta-analysis-10 comparative studies (16,442 neonates; 946 SSI 5.7%) showed that predictive factors for SSI development were gestational age, birth weight, age at surgery, length of surgical procedure, number of procedure per patient, length of preoperative hospital stay, and preoperative sepsis. Conversely, preoperative antibiotic use was not significantly associated with development of SSI. Conclusions: Younger neonates and those undergoing abdominal procedures are at higher risk for SSI. Given the lack of evidence-based literature, prospective studies may help determine the risk factors for SSI in neonates.

Validation of a Low-Cost Do-It-Yourself Model for Neonatal Thoracoscopic Congenital Diaphragmatic Hernia Repair

OBJECTIVE

We aimed to develop and validate a low cost, do-it-yourself model for neonatal thoracoscopic congenital diaphragmatic hernia (CDH).

DESIGN

Volunteers with varying skills in neonatal minimally invasive surgery tested and evaluated the model simulating a neonatal thoracoscopic CDH repair. The model was built from ordinary materials purchased in a dime store: a small food container, a neoprene band simulating a diaphragm, an inflated balloon simulating a spleen, a tissue chord simulating intestine, and a body wash sponge simulating a collapsed lung. The evaluation comprised 3 sets of 5-point grading scale concerning appearance, necessary maneuvers, and ability to generate skills. Bowel reduction and suture efficacy was verified for each test.

SETTING

Minimally invasive surgery simulation room at Pediatric Surgery Department of Hospital Universitario de Vall d'Hebron, Barcelona, Spain.

PARTICIPANTS

Volunteer residents and specialists of pediatric surgery.

RESULTS

Bowel reduction was possible in every test, with 1 spleen rupture, 1 bowel entrapment, and 2 inappropriate sutures due to tension. Most volunteers considered the general endoscopic vision (63.2%), external and internal dimensions (both 89.5%) to be highly similar; bowel reduction (68.4%) and diaphragm's manipulation and suture (57.9%) to be highly or very highly similar. Regarding its ability to generate skills, most considered it to be very or extremely useful concerning: camera handling (52.6%), working in small spaces and suture (both 100%), and tissue handling (63.2%). The least liked features were the colors and the diaphragm's tension. The size, portability, and the reproducibility were the most liked features.

CONCLUSIONS

We consider this low cost and easily reproducible model to be realistic enough for CDH repair training, having the potential to be adapted for other simulations.

In-utero aspiration vs expectant management of anechoic fetal ovarian cysts: open randomized controlled trial

OBJECTIVE

To assess the efficacy and safety of in-utero aspiration (IUA) of anechoic fetal ovarian cysts.

METHODS

This multicenter, prospective, randomized open trial in two parallel groups included women from nine outpatient fetal medicine departments with singleton pregnancy ≥ 28 weeks of gestation and a female fetus with an ultrasound-diagnosed simple ovarian cyst, defined as a single fully anechoic cystic structure measuring ≥ 30 mm. They were allocated randomly to IUA under ultrasound guidance or expectant management. All procedures were performed by trained senior obstetricians. Primary outcome was need for neonatal intervention, by laparoscopy, laparotomy or transabdominal aspiration. Secondary outcomes were in-utero involution of the cyst and oophorectomy at birth. Analyses were conducted according to the intention-to-treat principle.

RESULTS

Of 61 participants, 34 were allocated to IUA and 27 to expectant management. Three IUA procedures (9%) could not be performed (one due to fetal position and two due to aspirations being dry). The remaining 31 IUA procedures were uneventful. The incidence of neonatal intervention did not differ significantly between the IUA and the expectant management groups (20.6% vs 37.0%; relative risk (RR), 0.55; 95% CI, 0.24-1.27). Nonetheless, IUA was associated with increased incidence of in-utero involution of the cyst (47.1% vs 18.5%; RR, 2.54; 95% CI, 1.07-6.05) and reduced rate of oophorectomy (3.0% vs 22.0%; RR, 0.13; 95% CI, 0.02-1.03) compared with expectant management.

CONCLUSION

IUA of anechoic fetal ovarian cysts, compared with expectant management, was not associated with a reduction in overall neonatal interventions but was associated with a reduced oophorectomy rate. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Pediatric thoracoscopic repair of congenital diaphragmatic hernias

Congenital diaphragmatic hernia (CDH) is a rare congenital disease requiring neonatal surgical treatment. The traditional surgical management of CDH consists of diaphragmatic repair by laparotomy. Thoracoscopic repair techniques have been well described for CDH with late presentation. Nevertheless, its feasibility for CDH treatment in neonates emerged only the past few years because the use of thoracoscopy with carbon dioxide insufflation remains controversial in these patients more vulnerable to hypothermia and acidosis. However, we think that thoracoscopy can be safely used to repair CDH in selected patients and the major limiting factor is pulmonary hypoplasia. Some patients should be excluded based on their higher potential need for patch closure with its technical difficulty and increased operative time. The close collaboration between pediatric surgeon, anesthetist and neonatologist is essential. We discuss here the patient selection criteria, expose the pre- and post-operative management, the procedure steps; regarding to our experience we deliver some tips to achieve the safest surgical procedure for the pediatric patient.

Oesophageal replacement with stomach: A personal series and review of published experience

AIM

To describe the outcomes of oesophageal replacement using stomach in children.

METHODS

All children undergoing oesophageal replacement in a regional centre were prospectively recorded in a customised database and subjected to continual follow up. Complications within 30 days were classified as early, and all other complications were classified as late. Outcomes were related to a comprehensive analysis of published experience where studies were classified as having long-term follow up if the median duration exceeded 5 years.

RESULTS

Ten children underwent oesophageal replacement using the stomach between 1998 and 2016. Indications were oesophageal atresia (6), caustic ingestion (2), foreign body ingestion (1) and oesophageal hamartoma (1). Two children died at 2 and 7 months after gastric transposition. All survivors are under review, with a median follow up of 8.5 years (range 3-14 years). Complications occurred in every case. Among survivors, three had early complications and eight had late complications. Early complications included anastomotic leak (2) and lung compression by stomach (1). Late complications were anaemia (8), anastomotic stricture (7), oesophagitis (5), dumping syndrome (2), perforation of a jejunostomy (1), para-gastric hiatal hernia (1), gastric outlet obstruction (1), Barrett's oesophagus (1), prolonged inability to swallow (1) and recurrent lower respiratory tract infections (1). Among 57 publications, only three achieved complete long-term follow up. The incidence of reported complications was higher when follow up was complete.

CONCLUSIONS

Oesophageal replacement by gastric transposition in children leads to serious chronic morbidity. Published experience masks this because of incomplete and short follow up.

Let us save the brain with cerebral oximeter: Two case reports

In the neonates, tracheal atresia and tracheoesophageal fistula (TEF) surgery may result in hemodynamic instabilization, leading to cerebral perfusion insufficiency due to the retraction of the pulmonary vessels and truncus brachiocephalicus. We represented one male and one female neonates which were performed thoracoscopic primary repair of TEF through right thoracotomy at the 3^th and 4^th postpartum day. Anesthesia was induced using sodium thiopental (5 mg/kg), fentanyl 4 mcg, and rocuronium (0.5 mg/kg) given through intravenous route. Sevoflurane 2% and 50% O₂in air were used for the maintenance therapy. During the right lung compression to expose posterior esophagus, no value was observed on the pulse oximeter (PO) probe placed on the right hand, and radial artery was not palpated. At the same time, oxygen saturation was observed as 96%-97% on the left foot probe. As the right cerebral oximeter values (rSO₂) were rapidly decreased to 31%, the lung compression was ceased. Right pulse oximeter and right rSO₂measurements return to the baseline levels. For the second case - different from the first case -both left and right rSO₂was rapidly decreased to 40% levels and return to the baseline levels after was removed the retractors. Right PO and right and left cerebral rSO₂values returned to baseline immediately when the retractor compression was ended During the operations involving the great vessels in neonates, cerebral perfusion could be preserved using cerebral oximeter. Cerebral oximeter is more efficient than pulse oximeter for detecting cerebral tissue oxygenation and could be helpful to minimize neuronal damage in the neonates.

Risk factors for perioperative mortality and transfusion in sacrococcygeal teratoma resections

BACKGROUND

Sacrococcygeal teratomas are a common congenital tumor. Surgical resection can occur in utero, in the neonatal period, or in the postneonatal period.

AIMS

We describe patient and tumor factors associated with mortality and transfusion in this population.

METHODS

We did a retrospective chart review of patients who underwent sacrococcygeal teratoma resection between January 1998 and March 2016. Demographic data, transfusion data, and tumor characteristics were collected. Descriptive statistics were calculated, and univariate comparisons were performed with chi-square test and Fisher's exact test. Variables significant at univariate level were used in multivariate logistic regression and negative binomial regression.

RESULTS

Of the 112 cases, 6 were in utero repairs, 73 were neonatal repairs, and 33 were repairs at >30 days of life. There was 17%, 1%, and 0% intraoperative mortality and 33%, 5%, and 0% 30-day mortality in the in utero, neonatal, and >30 days of life repairs, respectively. All six patients who died within the first 30 days of life had a postmenstrual age of <32 weeks at time of surgery. All six patients who died had noncystic tumors. Patients with noncystic tumors were more likely to be born prior to 30-week gestation (23/65 vs 6/47; χ² = 7.3; P = 0.007). Gestational age >30 weeks was associated with decreased intraoperative death (0% vs 10%; modified maximum likelihood estimate of OR 0.05; 95% CI 0.002-0.96; P = 0.02). Gestational age >30 weeks (2.4% vs 13.8%; OR 0.15; 95% CI 0.03-0.89; P = 0.04) and cystic morphology (0% vs 9.2%; modified maximum likelihood estimate of OR 0.1; CI 0.01-1.75; P = 0.04) were associated with decreased 30-day mortality and emergent surgery (17.9% vs 1.2%; OR 18; 95% CI 2-162.2; P = 0.004) was associated with increased 30-day mortality. Gestational age >30 weeks (33.7% vs 62.1%; OR 0.27; 95% CI 0.09-0.79; P = 0.02) and Altman class 3-4 (12.1% vs 52.7%; OR 0.1; 95% CI 0.03-0.34; P = 0.0002) were associated with decreased need for transfusion and noncystic tumor was associated with increased transfusion volume (131.6 ml·kg^-1 [95% CI 94-184] vs 63 ml·kg^-1 [95% CI 40-100.1]; P = 0.01).

CONCLUSIONS

Prematurity is associated with increased intraoperative and 30-day mortality. Noncystic tumor morphology was the only significant factor associated with transfusion volume and all six patients who died had transfusion volumes of 240 ml·kg^-1 or greater. In these patients at high risk of mortality due to blood loss, the anesthesia team should be prepared to manage massive transfusion and coagulopathy with blood components and pharmacologic measures.

A novel approach in the treatment of neonatal gastroschisis: a review of the literature and a single-center experience

Gastroschisis is a congenital abdominal wall defect and its management remains an issue. We performed a review of the literature to summarize its evaluation, management and outcome and we describe a new type of surgical reduction performed in our center without anesthesia (GA), immediately after birth, in the delivery room. Between January 2002 and March 2013, we enrolled all live born infants with gastroschisis referred to the third-level Division of Obstetrics and Gynecology "San Camillo" of Rome. Two groups of infants were identified: group 1 in which gastroschis reduction was performed by the traditional technique and group 2 in which reduction was immediately performed after birth in the delivery room without GA. Twelve infants were enrolled in group 1, and seven infants in group 2. Statistical significance was observed between the groups regarding the hospital stay, for the duration of parenteral nutrition and full oral feeds (p = .004). Survival was similar between two groups. The reduction without GA performed immediately after birth in a delivery room encourages the relationship between the mother and her child and appears to be a safe and feasible technique in a selected group of patients with simple gastroschisis defect; for this reason, it could represent a valid alternative to traditional approach.

Monitoring Cerebral and Renal Oxygenation Status during Neonatal Digestive Surgeries Using Near Infrared Spectroscopy

BACKGROUND

Depending on the initial pathology, hypovolemia, intra-abdominal hypertension, and sepsis are often encountered in neonatal digestive surgery. Accurate newborn monitoring during and after surgery is essential to adapt resuscitation protocols. Near infrared spectroscopy (NIRS) is non-invasive and can detect hypoperfusion which indicates a low circulatory blood flow, regardless of the cause.

OBJECTIVE

Evaluating changes in cerebral and renal regional oxygen saturation during neonatal digestive surgeries, conducted according to normal practices, with commonly used monitoring parameters. Analyzing retrospectively the inter-relationships between NIRS values and mean arterial pressure (MAP) values as well as pre-ductal SpO₂.

METHODS

Prospective, descriptive, monocentric study. All neonates referred for surgery were included. NIRS allows the measurement of cerebral and renal oxygenation fluctuations, as well as calculating difference in intraoperative and postoperative values.

RESULTS

Nineteen patients were included. Cerebral regional oxygen saturation (C rSO₂) values were stable while renal regional oxygen saturation (R rSO₂) values tended to decrease with time during surgery. Indeed, 72% of rSO₂ decline episodes occurred after the first 30 min of surgery, without any significant statistical differences for the next 90 min of surgery. After surgery, the lowest average C and R rSO₂ values were evidenced during the first 6 h, with 60% of C rSO₂ and R rSO₂ anomalies occurring in that time frame. There was no significant statistical difference observed in the following 18 h. There was a significant correlation between R rSO₂ and SpO₂ values (p < 0.01), but not with C rSO₂ values. There was no correlation with the MAP either for the C rSO₂ values or R rSO₂ ones.

CONCLUSION

NIRS is a promising non-invasive bedside tool to monitor cerebral and tissue perfusion, analyzing tissue microcirculation. NIRS has its interest to guide neonatal digestive surgeries (bowel manipulation, viscera reduction) and may represent an early warning for identifying patients requiring resuscitation during or after these surgeries.

Attitudes of Parents and Health Care Workers to Major Surgery for High-Risk Preterm Infants

OBJECTIVES

To assess preferences of health care workers (HCWs) and parents of term and preterm infants to adverse health outcomes, and how perceived surgical mortality influences decision-making.

STUDY DESIGN

A total of 536 participants (157 HCWs, 201 parents of term infants, and 178 parents of preterm infants) were recruited to take part in a structured interview. Preferences related to treatment of a critically ill preterm infant with necrotizing enterocolitis were measured by health state rank permutation analysis and pivotal risk analysis. Between-group and subgroup comparisons were performed.

RESULTS

HCWs rank adverse health states less favorably than parents of preterm infants, consistently ranking 2 of the most adverse health states worse than death. Pivotal risk values of HCWs for all health states were consistently the lowest of the 3 groups. High operative mortality was associated uniformly with reduction in pivotal risks for all groups both in favorable and adverse health states. Subgroup analyses revealed significant discrepancies in preferences between fathers and mothers as well as doctors and nurses. Regular religious practice was significantly associated with increased pivotal risks in parental subgroups.

CONCLUSIONS

As discrepancies in health state preferences existed between subgroups (ie, doctors vs nurses, mothers vs fathers) and perceived operative mortality consistently biased parental and HCW health state preferences, we recommend that HCWs should first identify differences regarding patient management before interviewing the parents together. HCWs should be aware of inadvertently biasing parents when discussing the risks and outcomes of surgery in conjunction with the overall long-term prognosis of the underlying condition.

[Neonatal surgical emergencies at the Bukavu Provincial General Reference Hospital in Democratic Republic of Congo]

INTRODUCTION

This study aims to determine the prevalence of neonatal surgical emergencies and their epidemiology.

METHODS

This retrospective cohort study reports 30 cases whose data were collected in the Department of Surgery at the Bukavu Provincial General Reference Hospital over a period of 3 years, from January 2010 to December 2013.

RESULTS

Neonatal surgical emergencies account for 1.31% of surgical pathologies in general. The most frequent age of patients during medical consultation was less than 8 days. Male prevalence was noted with sex-ratio 3/2. The most frequent pathologies were gastrointestinal tract emergencies (43.3%) followed by neurological emergencies (40%). 80% of newborns underwent surgery. Mortality rate was 43.3%.

CONCLUSION

Neonatal surgical pathologies occur in our midst. Clinicians should be on alert and implement prenatal diagnostic programs and proper neonatal care management in order to save the lives of these children.

Intestinal perforation in premature neonates: The need for subsequent laparotomy after placement of peritoneal drains

AIM

In view of recent studies questioning the usefulness of peritoneal drainage (PD) in premature neonates with pneumoperitoneum, suggesting approximately 75% of those treated with PD needed delayed laparotomy, we reviewed the requirement for laparotomy after initial PD at our institution.

METHODS

Retrospective cohort of all premature infants with a diagnosis of intestinal perforation (ICD Code P78.0) from 1995 to 2012. Inclusion criteria were pneumoperitoneum on x-ray (isolated perforation or necrotising enterocolitis), birthweight <1800 g and gestational age <33 weeks.

RESULTS

Fifty patients met the criteria (38 PD, 12 primary laparotomy). Thirty-two per cent (95% CI 18-49%) received secondary laparotomy after initial PD. There was no significant difference when stratified according to isolated perforation (24%) versus necrotising enterocolitis (56%, P = 0.11). There was no significant difference between PD and primary laparotomy for time to full enteral nutrition, hazard ratio (HR) 0.99 (95% CI 0.48-2.04) or mortality, HR 2.15 (95% CI 0.48-9.63). The HR for mortality was partly confounded by birthweight, birthweight-adjusted HR 1.52 (95% CI 0.32-7.23).

CONCLUSIONS

Thirty-two per cent of neonates treated with primary PD received secondary laparotomy, with no significant difference in key outcomes. Primary PD still appears to be of benefit for those without features of necrotising enterocolitis.

Resting energy expenditure, macronutrient utilization, and body composition in term infants after corrective surgery of major congenital anomalies: A case-study

INTRODUCTION

Knowledge on the metabolic changes and nutritional needs during the postsurgical anabolic phase in infants is scarce. This analysis explores the associations of resting energy expenditure (REE) and macronutrient utilization with body composition of full-term infants, during catch-up growth after corrective surgery of major congenital anomalies.

METHODS

A cohort of full-term appropriate for-gestational-age neonates subjected to corrective surgery of major congenital anomalies were recruited after gaining weight for at least one week. REE and macronutrient utilization, measured by respiratory quotient (RQ), were assessed by indirect calorimetry using the Deltatrac II Metabolic Monitor ®. Body composition, expressed as fat-free mass (FFM), fat mass (FM) and adiposity defined as percentage of FM (% FM), was measured by air displacement plethysmography using the Pea Pod ®.

RESULTS

Four infants were included at 3 to 5 postnatal weeks. Recommended energy and macronutrient intakes for healthy term infants were provided. Through the study, the median (min-max) REE (Kcal/Kg FFM/d) was 70.8 (60.6-96.1) and RQ was 0.99 (0.72-1.20). Steady increases in both body weight and FFM were associated with initial decrease in FM and adiposity followed by their increase. Low RQ preceded decrease in adiposity.

CONCLUSION

The marked adiposity depletion, not expected during steady weight gain in the postsurgical period, prompts us to report this finding. The subsequent adiposity catch-up was associated with relatively high REE and RQ, suggesting preferential oxidation of carbohydrates and preservation of lipids for fat storage.

Theatre of paediatric surgery

In the 50 years since the first edition of this journal, operative paediatric surgery has undergone radical change. Many of the most common instruments are unchanged, both as a testament to their utility and in recognition of past surgeons remembered eponymously. Surrounding that basic core of instruments, theatre has changed radically as new tools and techniques have arisen. Surgeons have come down from their pedestals, recognising surgery as a team sport rather than a solo performance. More than half of the current paediatric surgical trainees are women, a higher proportion than in any other craft group of the Royal Australasian College of Surgeons. The appearance, and rapid development, of laparoscopy is to many observers the most notable change in surgery over the last 50 years. Placed in its context though, it is simply the most prominent example of a frameshift in surgical thinking. The patient as a whole is now the focus, rather than just the disease. Recent developments are as much about minimising harm to normal tissues as they are about extirpating pathology. As a surgical maxim, 'Primum non nocere' is even more in evidence in 2015 than it was in 1965.

Effect of sodium deficiency on growth of surgical infants: a retrospective observational study

BACKGROUND/AIM

Sodium is thought to be critical to growth. Infants who have an ileostomy may suffer from growth faltering, as sodium losses from stomas may be excessive. Urinary sodium measurements may indicate which patients could benefit from sodium supplementation; however, there is no consensus on what level of urinary sodium should be the cutoff for intervention. Our aim was to determine whether there is a relationship between urinary sodium and growth in infants undergoing ileostomy, colostomy and cystostomy.

METHODS

Following audit approval, a retrospective observational study of patient notes and chemical pathology data was carried out. All infants <1 year of age that had an ileostomy, colostomy, or cystostomy procedure between February 1997 and January 2014 were included. Patients' weights, urinary and serum sodium and potassium levels and clinical variables were recorded until discharge. Weights were converted to Z-scores for analysis.

RESULTS

Forty patients were identified whose notes were available for review and who had at least three urinary sodium measurements. During their hospital stay, 11 (28%) maintained weight within normal limits (Z-scores -2 to +2, 15 (38%) were moderately malnourished (-3 to -2) and 14 (35%) severely malnourished (<-3). Thirty patients had at least one urinary sodium <10 mmol/litre, six patients had their lowest recorded urinary sodium between 10 and 30 mmol/litre and only four patients had all their urinary sodium measurements >30 mmol litre. Electrolyte data were not normally distributed so that correlations between electrolytes and growth were tested using the non-parametric Spearman rank correlation coefficient. Urinary sodium levels positively correlated with growth (r = 0.3071, p < 0.0001), as did serum sodium levels (r = 0.2620, p = 0.0059) whereas there was no relationship between urine or serum potassium and growth.

CONCLUSIONS

Poor growth is frequent in this group of patients and appears to be linked with sodium levels. Further work is necessary to draw up guidelines for appropriate sodium supplementation.

Pediatric surgical care in Lilongwe, Malawi: outcomes and opportunities for improvement

BACKGROUND

One of the objectives of the Millennium Development Goals is to improve child health. We describe the burden of pediatric surgical disease at a tertiary hospital in Malawi.

METHODS

We conducted a retrospective analysis of a pediatric surgery database at Kamuzu Central Hospital in Malawi for the calendar year 2012. Variables included patient demographics, admission diagnosis, primary surgery and outcome.

RESULTS

A total of 1170 pediatric patients aged 0-17 years were admitted to the surgical service during the study period. The mean age was 6.9 years, and 62% were male. Trauma was the most common indication for admission (51%, n = 596), and 67% (n = 779) of all patients were managed non-operatively. Neonates and patients managed non-operatively had a significantly increased risk of mortality.

CONCLUSION

Only a third of patients admitted to the pediatric surgery service underwent surgery. More than half of patients with congenital anomalies did not undergo surgical intervention. Importantly, patients who underwent surgery had a survival advantage.

Emergency management of a congenital teratoma of the oral cavity at birth and three-year follow-up

Teratomas are congenital malformations that are rarely located in the head and neck region. We report a case of congenital teratoma of the oral cavity, which was causing an airway obstruction and was treated at the time of birth. This teratoma was discovered at 27 gestational weeks by ultrasonography. A multidisciplinary team was consulted for antenatal diagnosis; the options of therapeutic abortion or management of the birth with the prevention of respiratory distress were debated. However, preterm labour at 32 gestational weeks accelerated the parental and the medical decisions. The parents agreed to the birth. The various disciplines coordinated their work, and the predefined treatment plan for clearing the airway obstruction was applied to manage the birth. The reestablishment of patency of the airway was performed during delivery and removal of the tumour was performed immediately afterwards. The follow-up of this case over 3 years is also presented.

Fetal abdominal wall defects

The most common fetal abdominal wall defects are gastroschisis and omphalocele, both with a prevalence of about three in 10,000 births. Prenatal ultrasound has a high sensitivity for these abnormalities already at the time of the first-trimester nuchal scan. Major unrelated defects are associated with gastroschisis in about 10% of cases, whereas omphalocele is associated with chromosomal or genetic abnormalities in a much higher proportion of cases. Challenges in management of gastroschisis are related to the prevention of late intrauterine death, and the prediction and treatment of complex forms. With omphalocele, the main difficulty is the exclusion of associated conditions, not all diagnosed prenatally. An outline of the postnatal treatment of abdominal wall defects is given. Other rarer forms of abdominal wall defects are pentalogy of Cantrell, omphalocele, bladder exstrophy, imperforate anus, spina bifida complex, prune-belly syndrome, body stalk anomaly, and bladder and cloacal exstrophy; they deserve multidisciplinary counselling and management.

Postoperative decrease in plasma sodium concentration after infusion of hypotonic intravenous solutions in neonatal surgery

BACKGROUND

Hypotonic i.v. solutions can cause hyponatraemia in the context of paediatric surgery. However, this has not been demonstrated in neonatal surgery. The goal of this study was to define the relationship between infused perioperative free water and plasma sodium in neonates.

METHODS

Newborns up to 7 days old undergoing abdominal or thoracic surgery were included in this prospective, observational study. Collected data included type and duration of surgery, calculated i.v. free water intake, and pre- and postoperative plasma sodium. Statistical analyses were performed using the Pearson correlation, Mann-Whitney test, and receiver operating characteristic analysis with a 1000 time bootstrap procedure.

RESULTS

Thirty-four subjects were included. Postoperative hyponatraemia occurred in four subjects (11.9%). The difference between preoperative and postoperative plasma sodium measurements (ΔNaP) correlated with calculated free water intake during surgery (r=0.37, P=0.03), but not with preoperative free water intake. Calculated operative free water intake exceeding 6.5 ml kg(-1) h(-1) was associated with ΔNaP≥4 mM with a sensitivity and specificity [median (95% confidence interval)] of 0.7 (0.9-1) and 0.5 (0.3-0.7), respectively.

CONCLUSIONS

Hypotonic solutions and i.v. free water intake of more than 6.5 ml kg(-1) h(-1) are associated with reductions in postoperative plasma sodium measurements ≥4 mM. In the context of neonatal surgery, close monitoring of plasma sodium is mandatory. Routine use of hypotonic i.v. solutions during neonatal surgery should be questioned as they are likely to reduce plasma sodium.
