Device Closure of Hemodynamically Significant Patent Ductus Arteriosus in Premature Infants.

The patent ductus arteriosus is a very common condition in preterm infants, and a hemodynamically significant patent ductus arteriosus increases morbidity and mortality in these vulnerable patients. However, despite numerous randomized controlled trials, there is no consensus regarding management. Medical therapy is typically offered as first-line treatment, although it yields limited success and carries the potential for severe adverse events. In recent years, there has been rapid development in transcatheter patent ductus arteriosus closure primary with the use of the Amplatzer Piccolo Occluder, and this has gained widespread acceptance as a safe and effective alternative to surgical ligation in extremely low-birth-weight infants weighing over 700 g. This article aims to provide an appraisal of the patient selection process, a step-by-step procedural guide, and a comprehensive review of the outcomes associated with this approach.

Association between SMOF lipid and parenteral nutrition-associated cholestasis compared with Intralipid in extremely low birth weight infants: A retrospective cohort study.

BACKGROUND: There is limited evidence on benefits of SMOF lipids (mixed fatty acid emulsion of 30% soybean oil, 30% medium chain triglycerides, 25% olive oil, and 15% fish oil) in reducing parenteral nutrition-associated cholestasis in extremely low birth weight infants, compared with soybean oil-based Intralipid. AIM: To compare incidence of parenteral nutrition-associated cholestasis in preterm infants who received Intralipid vs SMOF lipid. METHODS: We conducted a retrospective study on infants with birth weight <1000 g, admitted between January 2013 to December 2022, who received parenteral nutrition for >14 days and divided them into two groups based on lipid emulsion received (Intralipid, n = 187, SMOF, n = 127). Primary outcome was incidence of parenteral nutrition-associated cholestasis, defined as direct bilirubin ≥2 mg/dl. RESULTS: Baseline characteristics did not differ between the two groups. No significant difference was noted in parenteral nutrition-associated cholestasis between the two groups on logistic regression, (adjusted odds ratio: 0.71, 95% confidence interval 0.35-1.42, P value 0.33) after adjusting for gestational age, parenteral nutrition days, lipid days, and late-onset sepsis. CONCLUSION: There was no difference in the rates of parenteral nutrition-associated cholestasis between preterm infants administered SMOF lipids and those given Intralipid.

Impact of Clinical Use of Probiotics on Preterm-Related Outcomes in Infants with Extremely Low Birth Weight.

Background: Preterm birth significantly contributes to mortality and morbidities, with recent studies linking these issues to gut microbiota imbalances. Probiotic supplementation shows promise in mitigating adverse outcomes in preterm infants, but optimal timing and guidelines remain unclear. This study assesses the benefits of probiotic supplementation for preterm infants without consistent guidelines. Methods: This retrospective study examined extremely low-birth-weight (ELBW) infants in neonatal intensive care units from 2017 to 2021. Mortality and preterm-related outcomes were compared between infants receiving probiotics and those not. Subgroup analyses based on probiotic initiation timing were conducted: early (≤14 days), late (>14 days), and non-probiotic groups. Results: The study included 330 ELBW infants: 206 received probiotics (60 early, 146 late), while 124 did not. Probiotic supplementation was associated with lower overall mortality (adjusted OR 0.22, 95% CI 0.09-0.48) and decreased mortality from necrotizing enterocolitis (NEC) or late-onset sepsis (LOS) (adjusted OR 0.12, 95% CI 0.03-0.45). Early probiotics reduced overall mortality, NEC/LOS-related mortality, and NEC/LOS-unrelated mortality. Late probiotics decreased overall mortality and NEC/LOS-related mortality. Early probiotic use also expedited full enteral feeding achievement. Conclusions: Probiotic supplementation reduces mortality and improves feeding tolerance in preterm infants. Establishing guidelines for probiotic use in this population is crucial.

Anesthetic management of extremely low-birth-weight neonates for laparotomy.

Anesthetic management of extremely low-birth-weight (ELBW) neonates is always accompanied by many dilemmas and challenges. Here, we report a case in which 512 g of ELBW newborns underwent exploratory laparotomy for perforation. Anesthesia management of such ELBW infants has not been reported in the literature.

Diuresis-led volume replacement strategy in extremely low birth weight infants.

AIM: In extremely low birth weight infants, fluid overload has been associated with bronchopulmonary dysplasia and death. Excessive weight loss may increase the risk of meconium obstruction and intestinal perforation. As these infants display oliguria followed by polyuria, we embarked on a diuresis-led volume replacement strategy as of January 2020. METHODS: This single-centre analysis presents data of infants <1000 g birth weight surviving for more than 3 days admitted 2017-2019 (n = 217, daily volume increase) versus 2020-2022 (n = 2022, diuresis-led volume replacement). RESULTS: The second cohort had lower gestational age (median [interquartile range]: 253/7 [243/7-264/7] vs. 263/7 [251/7-282/7] weeks), less antenatal steroids (58% vs. 69%), more indomethacin (66% vs. 47%) and higher initial diuresis (5.6 [4.9-6.8] vs. 4.8 [4.2-5.5] mL/kg/h) but did not differ by relative weight loss at Day 7 of life. Employing binary logistic regression with gestational age, antenatal steroids and indomethacin as covariates, the cohorts did not differ by rates of patent ductus arteriosus, abdominal surgery or severe retinopathy of prematurity, while there were significant declines in sepsis (from 32% to 19%), bronchopulmonary dysplasia (from 26% to 23%) and mortality (from 13% to 7%). CONCLUSION: Diuresis-led volume replacement appears to be safe and maybe beneficial.

Perinatal risk factors of renal outcome in former extremely low birth weight neonates.

Former Extremely Low Birthweight (ELBW) neonates suffer from adverse renal and cardiovascular outcomes later in life. Less is known about additional perinatal risk factors for these adverse outcomes which we have investigated in this study. We compared renal outcome between ELBW children and controls, to find perinatal risk factors for poorer renal outcome and to unveil associations between kidney function and blood pressure. This study included 93 former ELBW children and 87 healthy controls with a mean age of 11 years at assessment. We measured cystatin C-based estimated glomerular filtration rate (eGFR) and blood pressure. Blood pressure and eGFR levels were compared between cases and controls. We subsequently investigated perinatal risk factors for adverse outcome amongst ELBW children. ELBW children have significantly higher blood pressure (mean SBP percentile 75th vs. 47th, p <0.001) and lower mean eGFR (94 vs. 107 ml/min/1.73 m2, p = 0.005) compared to the control group. Elevated blood pressure did not correlate with perinatal characteristics and none of them had microalbuminuria. ELBW children with eGFR <90 ml/min/1.73 m2 were ventilated longer (17 vs. 9 days, p = 0.006), more frequently male (OR = 3.33, p = 0.055) and tended to suffer more from intraventricular hemorrhage (40% vs. 15.8%, p = 0.056). There was no association between blood pressure and kidney dysfunction. CONCLUSIONS: Understanding risk profiles for unfavorable outcomes may help to identify children at increased risk for kidney dysfunction. Poorer eGFR was associated with longer ventilation, male sex, and intra-ventricular hemorrhage but not with blood pressure. This knowledge can lead to safer neonatal therapeutic regimens for ELBW infants, a more intensive follow-up and earlier treatment initiation for children at highest risk. WHAT IS KNOWN: • Extremely Low Birthweight (ELBW) neonates suffer later in life from adverse renal and cardiovascular outcomes. • Perinatal risk factors that further predict the individual risk for adverse outcomes are not well known. WHAT IS NEW: • Poorer eGFR in adolescence was associated with male sex, longer ventilation and intra-ventricular hemorrhage at birth but not with blood pressure. • Former ELBW infants had higher blood pressures compared to controls, but no microalbuminuria. • This knowledge can lead to potential precision medicine, safer neonatal therapeutic regimens for ELBW infants, a more intensive follow-up and earlier treatment initiation for children at highest risk.

The Usefulness of Continuous Respiratory Sound Monitoring for the Detection of Pulmonary Atelectasis in a Ventilated Extremely Low Birth Weight Infant.

The assessment of auscultation using a stethoscope is unsuitable for continuous monitoring. Therefore, we developed a novel acoustic monitoring system that continuously, objectively, and visually evaluates respiratory sounds. In this report, we assess the usefulness of our revised system in a ventilated extremely low birth weight infant (ELBWI) for the diagnosis of pulmonary atelectasis and evaluation of treatment by lung lavage. A female infant was born at 24 weeks of age with a birth weight of 636 g after emergency cesarean section. The patient received invasive mechanical ventilation immediately after birth in our neonatal (NICU). After obtaining informed consent, we monitored her respiratory status using the respiratory-sound monitoring system by attaching a sound collection sensor to the right anterior chest wall. On day 26, lung-sound spectrograms showed that the breath sounds were attenuated simultaneously as hypoxemia progressed. Finally, chest radiography confirmed the diagnosis as pulmonary atelectasis. To relieve atelectasis, surfactant lavage was performed, after which the lung-sound spectrograms returned to normal. Hypoxemia and chest radiographic findings improved significantly. On day 138, the patient was discharged from the NICU without complications. The continuous respiratory-sound monitoring system enabled the visual, quantitative, and noninvasive detection of acute regional lung abnormalities at the bedside. We, therefore, believe that this system can resolve several problems associated with neonatal respiratory management and save lives.

Extremely rare cause of hyperkalemia: ileostomy‒induced hyperkalemia in extremely low birth weight infants.

BACKGROUND: Hyperkalemia is one of the most serious electrolyte disturbances, and it can cause lethal cardiac arrhythmia. Although hyperkalemia associated with ileostomies has been reported in adults, to the best of our knowledge, it has not previously been reported in neonates. CASE: We report ileostomy‒induced hyperkalemia that persisted during the ileostomy and resolved promptly after the closure of the ileostomy in two extremely low birth weight (ELBW) infants, with birth weights of 850 g and 840 g and gestational ages of 27 weeks and 27 weeks 6 days. CONCLUSIONS: These cases highlight that disruption of intestinal integrity in ELBW infants may cause hyperkalemia. Ensuring the integrity of the gastrointestinal tract plays an important role in the treatment of electrolyte disorders such as hyperkalemia in ELBW infants with an ileostomy.

Repair of infracardiac total anomalous pulmonary venous connection in a 902-gram infant with asplenia syndrome after failed umbilical venous catheter intervention.

Ductus venosus stenting via a transumbilical approach for pulmonary venous obstruction in infracardiac total anomalous pulmonary venous connection has been described. In a 902-gram infant who was diagnosed with asplenia syndrome and infracardiac total anomalous pulmonary venous connection, ductus venosus stenting was attempted by a transumbilical approach. However, ductus venosus stenting was discontinued due to bleeding from the portal vein. The bleeding subsided in time spontaneously, and total anomalous pulmonary venous connection repair with pulmonary artery banding was performed on 21 days after birth. To our knowledge, this is the first report that describes total anomalous pulmonary venous connection repair in a neonate under 1000 g body weight. Learning objective: Ductus venosus stenting is an effective palliative option, especially in the presence of high surgical risk, such as heterotaxy syndrome and a low birth weight. However, ductus venosus stenting should carefully be evaluated by assessment of anatomical configuration of umbilical vein and ductus venosus. If ductus venosus stenting is anatomically difficult, primary surgical repair may be an option even in an extremely low birth weight infant.

Unusual Presentation of Beckwith-Wiedemann Syndrome in an Extremely Low Birth Weight Infant.

Beckwith-Wiedemann syndrome (BWS) is a genetic disorder that affects fetal growth in which those afflicted present with features pertaining to that, such as macrosomia, macroglossia, hemihypertrophy, and abdominal wall defects. This case reports the presentation of an infant diagnosed with BWS who was born with an extremely low birth weight of 980 grams, in contrast to the typical presentation of overgrowth and macrosomia. As a result, reaching a diagnosis of BWS was delayed until the patient reached eight months of age, when other clinical features of BWS, such as hemihypertrophy, became apparent on follow-up visits. Although genetic testing can be used to diagnose this condition, a clinical scoring system consisting of a patient's clinical features is sufficient, allowing for a timely and precise diagnosis, which is of great significance to allow for early screening and detection of the associated embryonal tumors with such a syndrome.

Enteral Feedings Do Not Increase the Risk of NEC in ELBW Infants Undergoing Treatment of Patent Ductus Arteriosus With Acetaminophen.

OBJECTIVE: Acetaminophen (APAP) is an alternative to indomethacin and ibuprofen for treatment of patent ductus arteriosus (PDA). The side effect profile of non-steroidal anti-inflammatory drugs (NSAIDs) presents enteral feeding safety concerns; however, the safety of enteral feeding on APAP is largely unknown. Optimal feeding strategies during pharmacological PDA treatment are unknown, leading to practice variation. This study aims to assess the incidence of adverse gastrointestinal (GI) outcomes in neonates treated with APAP for PDA closure while receiving enteral feedings. METHODS: Single-center retrospective cohort study of 59 extremely low birth weight (ELBW), premature neonates who received APAP for PDA treatment divided into Low Volume (LV; ≤ 20 mL/kg/day) and High Volume (HV; > 20 mL/kg/day) enteral feeding groups. The primary outcome was the incidence of any suspected or confirmed necrotizing enterocolitis (NEC). Timing of nutrition milestones, parenteral nutrition (PN) days, and adverse outcomes (feeding intolerance, liver dysfunction, death prior to discharge) were evaluated. RESULTS: The incidence of suspected or confirmed NEC was 19.5% in the LV group and 13.3% in the HV group (p = 0.593). The HV group reached full feeds 6 days sooner (18 vs 24 days, p = 0.024) and had fewer PN days (17 vs 23.5 days, p = 0.044) with no difference in adverse outcomes. CONCLUSIONS: Provision of > 20 mL/kg/day of enteral feeds during APAP treatment of PDA decreased time to full feeds and PN days compared to trophic feedings (≤ 20 mL/kg/day) with no difference in adverse GI outcomes. Continuing enteral feeding during APAP PDA treatment appears safe while improving achievement of nutritional milestones.

Efficacy of bowel ultrasound to diagnose necrotizing enterocolitis in extremely low birthweight infants.

BACKGROUND: Bowel ultrasound (US) is one of the methods used to enhance diagnostic accuracy of necrotizing enterocolitis (NEC) and its associated complications in premature newborns. AIM: To explore the diagnostic accuracy of bowel US in extremely low birth weight (ELBW) infants with NEC. METHODS: A single-center retrospective case-control study included 84 extremely low birth weight (ELBW) infants. The infants were divided into three groups: Group 1 -infants with NEC (n = 26); Group 2 -infants with feeding problems (n = 28); Group 3 -control group (n = 30). RESULTS: The specific bowel US findings in premature newborns with NEC (stage 3) included bowel wall thinning, complex (echogenic) ascites, and pneumoperitoneum, p < 0.05. The diagnostic effectiveness of these sonographic signs was 96.8% (sensitivity 75.0% and specificity 97.6%), p < 0.05. These findings with high specificity were associated with the need for surgical intervention, poor outcomes, or increased mortality. Stage 2 NEC which did not require surgery showed impaired differentiation of the bowel wall layers, absent or decreased bowel peristalsis, pneumatosis intestinalis, portal venous gas, or simple ascites, with a diagnostic accuracy of 82.9% (sensitivity 55.6%, specificity 91.4%, p < 0.05). CONCLUSIONS: Bowel US can be used as an adjunct to abdominal radiography to aid in the diagnosis of infants with suspected NEC by providing more detailed evaluation of the intestine.

Percutaneous Drainage for Giant Pulmonary Interstitial Emphysema in a Tiny Infant with a Birth Weight of 327 g.

Giant pulmonary cyst in extremely low birth weight (ELBW) infants has been described as one of severe pulmonary diseases. Any definitive therapy for refractory cases, where conservative methods of treatments are not effective, has not been established as a standard. Herein, we report an ELBW infant with a giant pulmonary cyst cured by percutaneous drainage without any adverse events. A female infant was born with a birth weight of 327 g. Surfactant was administered on days 1 and 2 of life to treat respiratory distress syndrome. Tracheal intubation was performed and synchronized intermittent mandatory ventilation was promptly initiated following birth. On the course, right giant pulmonary cyst developed on day 9 after birth. Although we started conservative therapy, including right lateral decubitus positioning, high-frequency oscillatory ventilation, and systemic corticosteroid administration, the diameter of the cyst had reached 34 mm, and mediastinal displacement was observed on day 28 after birth when she weighed 393 g. She recovered by percutaneous drainage followed by suction with a pressure of -10 cm H 2 O under mild sedation for 3 days. We believe that percutaneous drainage can be one of the available options for unilateral pulmonary interstitial emphysema.

Successful Atrial Septal Defect Closure Subsequent to Medical Pulmonary Preconditioning in an Infant With Severe Pulmonary Hypertension Associated With Bronchopulmonary Dysplasia.

While atrial septal defect (ASD) may contribute to right ventricular decompression in patients with severe pulmonary hypertension (PH), the pulmonary vasculature might be compromised by increased pulmonary blood flow, even though pulmonary vasodilators successfully reduce resistance. ASD closure is a treatment option that may ameliorate PH symptoms associated with bronchopulmonary dysplasia (BPD) in infants. However, the feasibility of ASD closure is obscure in patients with BPD-PH causing right-to-left shunting. Here, we present an eight-month-old girl with ASD complicated by BPD-PH, in which the pulmonary pressure exceeded the systemic pressure; the ASD was successfully closed after pulmonary preconditioning with dexamethasone and high-dose diuretics. Our patient was delivered as the third baby in triplets at a gestational age of 25 weeks, with a birth weight of 344 g. She was diagnosed with BPD at three months of age (37 weeks of postmenstrual age) with a body weight of 1.4 kg. Mild pulmonary hypertension was identified at the age of five months, and oral sildenafil was initiated. While her atrial septal defect was small at the time of PH diagnosis, it became hemodynamically significant when she grew up to 3.4 kg of body weight, at seven months after birth. Her estimated right ventricular pressure was apparently more than the systemic pressure, and oxygen saturation fluctuated between 82% and 97% under oxygen supplementation due to bidirectional interatrial shunt with predominant right-to-left shunting. Pulmonary preconditioning lowered the estimated right ventricular pressure to almost equal the systemic pressure and elevated arterial oxygen saturation while also suppressing right-to-left shunting. Cardiac catheterization after preconditioning revealed a ratio of pulmonary blood pressure to systemic blood pressure ratio (Pp/Ps) of 0.9, pulmonary resistance of 7.3 WU-m2, and a pulmonary to systemic blood flow ratio (Qp/Qs) of 1.3 (approximately 1.0 in the normal circulation without significant shunt), with the cardiac index of 2.8 L/min/m2. The acute pulmonary vasoreactivity test against the combination of 20 ppm nitric oxide and 100% oxygen was negative, although the patient had consistently high pulmonary flow with makeshift improvements after preconditioning. Despite the high pulmonary resistance even after preconditioning, aggressive ASD closure was performed so that pulmonary flow could be consistently suppressed regardless of the pulmonary condition. Her Pp/Ps under 100% oxygen with 20 ppm nitric oxide was 0.7 immediately after closure. After two years of follow-up, her estimated right ventricular pressure was less than half of the systemic pressure with the use of three pulmonary vasodilators, including sildenafil, macitentan, and beraprost. A strategy to temporarily improve PH and respiratory status aimed at ASD closure could be a treatment option for the effective use of multiple pulmonary vasodilators, by which intensive treatment of BPD can be achieved.

Outcomes of High-Dose Inhaled Nitric Oxide and Oxygen Administration for Severe Pulmonary Hypertension With Bronchopulmonary Dysplasia.

Pulmonary hypertension (PH) with bronchopulmonary dysplasia (BPD) is fraught with high infant mortality rates. However, the intervention strategy for severe PH is unclear. This case report discusses the utility of long-term high-dose inhaled nitric oxide (iNO) administration and that of oxygen therapy for the prevention of PH deterioration. A male infant weighing 864 g was delivered at a gestational age of 24 weeks and three days. The patient who had severe BPD was diagnosed with PH at a corrected gestational age (CGA) of 43 weeks. Although oxygen was administered to prevent PH, the patient still developed severe PH. Despite long-term high-dose (iNO) administration, the patient could not survive. The abovementioned treatment may exacerbate PH, and oxygen administration is less effective for the prevention of PH deterioration with BPD.

A rare case of extremely low birth weight infant with Beckwith-Wiedemann syndrome.

INTRODUCTION: Beckwith-Wiedemann syndrome (BWS) manifests distinctive features, such as macroglossia, overgrowth, and abdominal wall defects. In this report, we describe a case of BWS in an extremely low birth weight infant diagnosed at three months after birth because of the intensive care for low birth weight. PRESENTATION OF CASE: A female infant was delivered at 24 weeks and 6 days of gestation with a weight of 845 g. After birth, significant small intestinal intra-umbilical prolapse was observed, and abdominal wall closure using a sutureless method was performed on day zero. Careful neonatal management was performed; however, an episode of bloody stools led to a diagnosis of intestinal volvulus due to intestinal malrotation. At 119 days of age, the Ladd procedure was performed. Notably, during anaesthesia induction, features suggestive of BWS were observed, leading to its diagnosis. DISCUSSION: Early diagnosis of BWS is vital because of its association with tumors. However, because she was an extremely low birth weight infant who required oral intubation and supine management for respiratory control, nevus flammeus and macroglossia were not observed. Therefore, BWS was not diagnosed for approximately three months after birth. It is important to recognize that omphalocele in extremely low birth weight infants is a risk factor for delayed diagnosis of BWS. CONCLUSION: Timely diagnosis of BWS is critical because of its association with tumors and varied clinical presentations. Early screening, especially for tumors, and awareness among surgical practitioners can aid in timely interventions and improved patient outcomes.

Evaluation of Postoperative Outcomes After Enterostomy Closure in Low Body Weight Infants: A Multi-Center Retrospective Analysis.

BACKGROUND: The minimum weight for enterostomy closure (EC) in infants remains debated with the current acceptable cut-off of >2 kg. As enterostomy-related complications or high enterostomy output (>30cc/kg/d) may prohibit a premature infant from reaching 2 kg, additional data is needed to evaluate the safety of EC in infants <2 kg. The objective of this study was to evaluate postoperative outcomes in low body weight (<2 kg) infants undergoing EC compared to larger infants. METHODS: We performed a multi-center retrospective analysis from 1/1/2012-12/31/2022 of all infants (age <1 year) who were <4 kg at time of EC. Primary outcomes included postoperative complications and 30-day mortality. Non-parametric analysis was performed using the Kruskal-Wallis one-way analysis of variance and chi-square tests. Univariable logistic regression was performed to identify factors associated with postoperative complications. RESULTS: Of 92 infants, 15 infants (16.3%) underwent EC at <2 kg, 16 (17.4%) at 2-2.49 kg, 31 (33.7%) at 2.5-2.99 kg, and 30 (32.6%) at ≥3 kg. Infants <2 kg at time of EC exhibited higher rates of hyperbilirubinemia (P = .030), neurologic comorbidities (P = .030), and high enterostomy output (P = .041). There was no difference in postoperative complications (P = .460) or 30-day mortality (P = .460) between the <2 kg group and larger weight groups. Low body weight was not associated with an increased risk for developing a postoperative complication (OR: 1.001, 95% CI: 1.001-1.001; P = .032). CONCLUSION: Our findings suggest that EC in infants <2 kg may be safe with comparable postoperative outcomes to larger weight infants. Thus, the timing of EC should be based on the infant's physiologic status, in contrast to a predetermined minimum weight cut-off.

Clinical Impact of Supplementation with Pasteurized Donor Human Milk by High-Temperature Short-Time Method versus Holder Method in Extremely Low Birth Weight Infants: A Multicentre Randomized Controlled Trial.

Nosocomial infections are a frequent and serious problem in extremely low birth weight (ELBW) infants. Donor human milk (DHM) is the best alternative for feeding these babies when mother's own milk (MOM) is not available. Recently, a patented prototype of a High-Temperature Short-Time (HTST) pasteurizer adapted to a human milk bank setting showed a lesser impact on immunologic components. We designed a multicentre randomized controlled trial that investigates whether, in ELBW infants with an insufficient MOM supply, the administration of HTST pasteurized DHM reduces the incidence of confirmed catheter-associated sepsis compared to DHM pasteurized with the Holder method. From birth until 34 weeks postmenstrual age, patients included in the study received DHM, as a supplement, pasteurized by the Holder or HTST method. A total of 213 patients were randomized; 79 (HTST group) and 81 (Holder group) were included in the analysis. We found no difference in the frequency of nosocomial sepsis between the patients of the two methods-41.8% (33/79) of HTST group patients versus 45.7% (37/81) of Holder group patients, relative risk 0.91 (0.64-1.3), p = 0.62. In conclusion, when MOM is not available, supplementing during admission with DHM pasteurized by the HTST versus Holder method might not have an impact on the incidence of catheter-associated sepsis.

We Reduced the Incidence of Postoperative Complications in Neonatal Ostomy Patients by Using Simple Devices.

Background: Complications frequently occur after neonatal enterostomy. Enterostomy formation is a common outcome following an emergency neonatal laparotomy. This study investigated whether the incidence of complications after enterostomy could be decreased with a drainage device (composed of foreskin cerclage staple, a condom, and a 0-Mersilk braided nonabsorbable suture) fixed in the proximal ostomy bowel tube to improve proximal enterostomy in newborns. Methods: This study was a retrospective case note review of the incidence of emergency neonatal enterostomy incidence over a 3-year period (2/2016-2/2019) at the authors' center. A single surgeon conducted all surgeries. The incidence of intraoperative and postoperative complications was compared between modified and traditional surgery groups. Results: All 47 surgeries were successfully completed (32 boys and 15 girls; sex ratio: 2.13:1). The mean (±SD) birth weight, gestational period, and daily age were 2.64 ± 0.81 kg 35.62 ± 3.76 weeks and 3.49 ± 5.61 days, respectively. The patients were divided into modified surgery groups (20 cases) and traditional surgery groups (27 cases). The modified surgery group had significantly lower rates of total complications, unplanned reoperations, wound-related complications, and stoma-related complications than the traditional group (p <0.05). Conclusions: The preliminary observations suggested that the simple drainage device was a safe and effective operation device that reduced the risk of stoma-related complications.
