Background: The management of Gastroschisis in LMICs continues to be a challenge and is associated with very poor outcomes in contrast with HICs where survival rates near 100%. The purpose of this work is to provide an overview of survival over the past 8 years in a high-flow tertiary centre in Africa. It also investigates the effect of transfer-time and time-to-surgery on outcome. Methods: Retrospective case note review of all GS admissions. The variables assessed were gender, gestational age, weight, type of GS, transfer time, time to surgery and type of surgery. The primary outcome was survival. Results: A total of 171 GS cases were identified: 148 simple, 23 complex. Seven died before surgery. The median age at surgical intervention was 8.5 h (range, 0–48). Closure options ranged from single-staged (primary fascial, skin, umbilical flap and sutureless closure) or a staged (silo) closure. Overall survival was 34.5%. Cases transferred under 8 h had a 46% survival. Surgery under 12 h of life had highest survival, 45%. Simple GS survived better than complex GS (40% vs 10%). Primary closure had a significantly better survival compared to staged closure (51% vs 18%). Conclusions: Transfer-time < 8 h plays a vital role in survival of GS cases. Surgical intervention within 12 h of birth showed a statistically significant improvement in outcome. Primary closure was associated with better survival rates. Level of Evidence: Level III.

Purpose: Improved perioperative care has enhanced survival in children with congenital gastrointestinal conditions and abdominal wall defects (AWD). However, epidemiological and surgical outcomes in developing nations are still scarce. Our aim was to assess the burden and mortality of common congenital gastrointestinal anomalies and AWD in Malaysia, and their influencing factors. Methods: Using the Global PaedSurg study protocol with permission, we performed a prospective cohort study on children presenting for the first time between October 2021 and April 2022 with these conditions: Esophageal atresia (EA), congenital diaphragmatic hernia (CDH), intestinal atresia, gastroschisis, exomphalos, anorectal malformation (ARM) and Hirschsprung's disease. We compared mortality and 30-day outcome data across different geographical regions in Malaysia. Results: There were 228 patients with 242 study conditions (EA n = 28, CDH n = 36, intestinal atresia n = 49, gastroschisis n = 12, exomphalos n = 8, ARM n = 77, Hirschsprung's disease n = 32). Our mortality rate was 8.8%; 60% of these were CDH patients. Factors significantly associated with mortality were CDH diagnosis, central venous access requirement, higher American Society of Anesthesiologists (ASA) score, blood transfusion and ventilation requirement. Conclusion: Diagnosis of CDH is the most important predictor for sepsis on arrival and mortality, therefore measures should be taken for early recognition and aggressive management.

Implantable biomedical patch used in treating abdominal wall defects requires antibacterial, anti‐adhesion, and pro‐healing activities to ensure surgical success and prevent postsurgical complications. However, it often encounters challenges in fulfilling these three critical properties simultaneously, as these processes can always be contradictory during treatment. Herein, to break the barriers between bactericidal activity and cytocompatibility, cell adhesion and anti‐adhesion, a bio‐inspired patch with an asymmetric Janus structure is developed. This bio‐inspired Janus patch features cicada wing‐inspired nanostructures on its top surface, enabling both mechano–bactericidal effects and promotion of fibroblast adhesion and proliferation, which stems from its inherent "selective biocidal activity" toward bacteria and mammalian cells. Subsequently, a poly‐zwitterion layer with robust nonfouling properties is grafted on the bottom surface, realizing cell adhesion and anti‐adhesion on two sides of the same patch. Compared to the commercially available polypropylene (PP) meshes, the top surface of the Janus patch, which faces the abdominal wall, demonstrates superior capabilities in preventing postoperative infection and promoting tissue repair. Simultaneously, the other side facing the viscera efficiently prevents any visceral tissue adhesion. With these prominent performances, the bio‐inspired Janus patch presents a pioneering strategy for designing next‐generation patches to treat abdominal wall defects. [ABSTRACT FROM AUTHOR]

Omphalocele and gastroschisis are the most common types of abdominal wall defects. Comprehensive local experience helps parents to make decisions on the pregnancy and foresee the disease journey. A retrospective review of abdominal wall defect patients in all three pediatric surgical centers in Hong Kong between January 2003 and February 2023 was conducted. All patients consecutively diagnosed with omphalocele and gastroschisis were included, excluding other forms. Data of demographics and short- and long-term outcome parameters were collected. A total of 99 cases were reviewed and 85 patients met the inclusion criteria. Diagnoses include omphalocele major (n = 49, 57.6%), omphalocele minor (n = 22, 25.9%) and gastroschisis (n = 14, 16.5%), with mean gestational age 37 weeks (SD 2.2) and birth weight 2.7 kg (SD 0.6). Omphalocele is most commonly associated with cardiovascular (n = 28, 39.4%) and chromosomal defects (n = 11, 15.5%). Surgical procedures including primary repair (n = 38, 53.5%), staged closure (n = 30, 42.3%) with average 8.6 days (SD 4.7) of silo reduction, and conservative management (n = 3, 4.2%) were performed. The mortality rate was 14.1% (n = 10) and the complication rate was 36.6% (n = 26). The majority of patients had normal intellectual development (92.5%) and growth (79.2%) on the latest follow-up. For gastroschisis, one patient (7.1%) had intestinal atresia. Surgical procedures included primary repair (n = 9, 64.3%) and staged closure (n = 5, 35.7%) with average 8 days (SD 3.5) of silo reduction. Complication rate was 21.4% (n = 3), with one mortality (7.1%). All patients had normal intellectual development and growth. The mean follow-up time of this series is 76.9 months (SD 62.9). Most abdominal wall defects in our series were managed surgically with a good overall survival rate and long-term outcome. This information is essential during antenatal and postnatal counseling for parents. [ABSTRACT FROM AUTHOR]

Fetal abdominal wall defects (AWDs) refer to a variety of congenital anomalies characterized by the incomplete closure or disruption of the abdominal wall in the early stages of embryonic development. Based on the 2011 European Surveillance of Congenital Anomalies (EUROCAT) report, the general prevalence of fetal abdominal wall defects is documented to be six cases per 10,000 births. AWDs pose significant challenges for prenatal diagnosis and management. Ultrasound has emerged as an indispensable tool in diagnosing and characterizing various abdominal wall defects early in pregnancy, enabling precise prenatal counseling and appropriate antenatal management strategies. This article provides a general review of the specialized literature regarding various types of abdominal wall defects, such as omphalocele, gastroschisis, pentalogy of Cantrell, bladder exstrophy, and limb body wall complex, highlighting the significant sonographic features observed during ultrasound examination. Additionally, differential diagnoses are explored, emphasizing the importance of accurately distinguishing between these conditions to ensure optimal management strategies. This article aims to enhance the understanding and familiarity of ultrasound practitioners and obstetricians with the spectrum of fetal abdominal wall defects and their prenatal sonographic appearance, thus facilitating improved prenatal care and patients’ counseling.

As an alternative for currently available hernia meshes, electrospun scaffolds represent good biocompatibility and favorable healing performance. However, they usually cannot meet the minimum mechanical requirements for a successful hernia repair. Here, a double‐faced hernia mesh comprised of electrospun polycaprolactone fibers (PCL) and chitosan nanofibers (CS) is developed to address this limitation. The privileged fibrous structure of PCL, in visceral side, can potentially guarantee the required mechanical criteria to withstand intra‐abdominal pressures and minimizing adverse adhesions. On the ventral side (facing incision), a stabilized CS layer is developed to improve cellular behavior and tissue regeneration. According to the results, PCL‐CS scaffold (thickness ≈ 500 µm) properly matches with the mechanical properties of native abdominal wall and closely meets the suggested thresholds in strength (33.3 N cm−1) and elasticity (15.26%). Superior cytocompatibility of PCL‐CS is confirmed by the in vitro studies using L929 fibroblasts and human umbilical vein endothelial cells. Full‐thickness abdominal wall defects are used to compare tissue regeneration and adverse adhesions for PCL‐CS with the polypropylene commercial mesh (Prolene) and suture groups. Gross examinations demonstrate lower rate of unfavorable adhesions in PCL‐CS compared to Prolene and suture groups. Concerning the histological analyses, PCL‐CS exhibits reduced inflammation, less fibrosis, and better tissue remodeling. [ABSTRACT FROM AUTHOR]

Beckwith-Wiedemann syndrome (BWS) is a rare and heterogeneous genetic condition characterized by overgrowth, organomegaly, and increased vulnerability to embryonal tumors. This review investigates the complex genetic and epigenetic pathways underlying Beckwith-Wiedemann syndrome, focusing on the 11p15.5 region on chromosome 11. Abnormalities in the 11p15.5 area, such as imprinting control region dysregulation and CDKN1C gene mutations, contribute to disrupted growth regulation. This content also provides an overview of the incidence and pathophysiology of this syndrome. Clinical manifestations include macrosomia, macroglossia, and abdominal wall abnormalities. The increased risk of embryonal malignancies, such as Wilms tumor and hepatoblastoma, emphasizes the importance of diligent medical observation. Early diagnosis through genetic testing is crucial for tailored management and genetic counseling. This detailed discussion of Beckwith-Wiedemann syndrome sheds light on the molecular complexities of the condition, emphasizing the significance of genetic testing, early detection, and multidisciplinary management for affected infants.

Complex gastroschisis defines cases with abdominal wall defect associated with intestinal atresia, stenosis, volvulus, necrosis, or perforation. In this work we present the clinical case of female, 37 weeks gestation. Heredofamilial history, no relevant data. Prenatal history: G1, A0, diagnosed with gastroschisis in the first trimester. Postnatal history: born via abdominal delivery, ++ meconium-stained amniotic fluid, flaccid, no respiratory effort, Silverman-Andersen 4, APGAR 6/8, weight 2,720 grams, length 48 cm, head circumference 32 cm, chest circumference 26 cm, abdominal circumference 26 cm, foot length 7 cm. Current condition: developed meconium aspiration syndrome and complex gastroschisis at birth. Diffuse infiltrates on chest X-ray. Surgical findings: colonic atresia with transmural necrosis of cecal wall, including the vermiforme cecal appendix and ileocecal valve. Thick, adherent meconium pellets in the terminal ileum. Ileostomy was performed to facilitate meconium management through enemas. At 14 days, abdominal plasty and ileocolic anastomosis were performed without complications. Oral administration of acetylcysteine resumed after 5 days and was discontinued at one month of age without complications. Complementary studies and follow-up: weat electrolytes ruled out cystic fibrosis, and neonatal screening was normal. Current follow-up at 1 year and 6 months shows. Weight within normal limits. Low height, under surveillance. Developmental delay, so she is included in an early stimulation program. Complex gastroschisis requires multiple surgeries and is associated with higher morbidity and mortality than simple gastroschisis. Timely management can change the morbidity outcome.

This research analysed early neonatal outcomes of complex and simple gastroschisis following planned elective preterm delivery in relation to prenatal ultrasound assessment of bowel conditions. A retrospective study of 61 neonates with prenatal gastroschisis diagnosis, birth, and management at a single tertiary centre from 2011 to 2021 showed a 96.72% survival rate with no intrauterine fatalities. Most cases (78.7%) were simple gastroschisis. Neonates with complex gastroschisis had longer hospital stays and time to full enteral feeding compared to those with simple gastroschisis—75.4 versus 35.1 days and 58.1 versus 24.1 days, respectively. A high concordance of 86.90% between the surgeon's and perinatologist's bowel condition assessments was achieved. The caesarean delivery protocol demonstrated safety, high survival rate, primary closure, and favourable outcomes compared to other reports. Prenatal ultrasound effectively evaluated bowel conditions and identified complex gastroschisis cases. [ABSTRACT FROM AUTHOR]

Abdominal wall defects are serious birth defects, with long periods of hospitalization and significant costs to the medical system. Nosocomial infection (NI) may be an additional risk factor that aggravates the evolution of newborns with such malformations. Methods: in order to analyze the factors that may lead to the occurrence of NI, we performed a retrospective study over a period of thirty-two years (1990–2021), in a tertiary children's hospital; 302 neonates with omphalocele and gastroschisis were eligible for the study. Results: a total of 33.7 % patients were infected with one or more of species of bacteria or fungi. These species were Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp., Staphylococcus spp., Enterococcus spp. or Candida spp., but the rate of NI showed a significant decrease between the 1990–2010 and 2011–2021 period (p = 0.04). The increase in the number of surgeries was associated with the increase in the number of NI both for omphalocele and gastroschisis; in the case of gastroschisis, the age of over 6 h at the time of surgery increased the risk of infection (p = 0.052, marginal statistical significance). Additionally, for gastroschisis, the risk of NI was 4.56 times higher in the presence of anemia (p < 0.01) and 2.17 times higher for the patients developing acute renal failure (p = 0.02), and a hospitalization period longer than 14 days was found to increase the risk of NI 3.46-fold (p < 0.01); more than 4 days of TPN was found to increase the NI risk 2.37-fold (p = 0.015). Using a logistic regression model for patients with omphalocele, we found an increased risk of NI for those in blood group 0 (OR = 3.8, p = 0.02), in patients with a length of hospitalization (LH) of ≥14 days (OR = 6.7, p < 0.01) and in the presence of anemia (OR = 2.5, p = 0.04); all three independent variables in our model contributed 38.7% to the risk of NI. Conclusion: although in the past 32 years we have seen transformational improvements in the outcome of abdominal wall defects, there are still many factors that require special attention for corrections.

BACKGROUND: Gastroschisis and omphalocele are the 2 most common congenital fetal abdominal wall defects. Both malformations are commonly associated with small-for-gestational-age neonates. However, the extent and causes of growth restriction remain controversial in both gastroschisis and omphalocele without associated malformations or aneuploidy. OBJECTIVE: This study aimed to examine the role of the placenta and the birthweight–to–placental weight ratio in fetuses with abdominal wall defects. STUDY DESIGN: This study included all cases of abdominal wall defects examined at our hospital between January 2001 and December 2020, retrieving the data from the hospital's software. Fetuses with any other combined congenital anomalies, known chromosomal abnormalities, or lost to follow-up were excluded. Overall, 28 singleton pregnancies with gastroschisis and 24 singleton pregnancies with omphalocele met the inclusion criteria. Patient characteristics and pregnancy outcomes were reviewed. The primary outcome was to investigate the association between birthweight and placental weight in pregnancies with abdominal wall defects as measured after delivery. To correct for gestational age and to compare total placental weights, ratios between the observed and expected birthweights for the given gestational age in singletons were calculated. The scaling exponent β was compared with the reference value of 0.75. Statistical analysis was performed using GraphPad Prism (version 8.2.1; GraphPad Software, San Diego, CA) and IBM SPSS Statistics. A P value of

Background: Gastroschisis (GS) and omphalocele (OC) are congenital abdominal wall defects, the main difference between is the direct exposure of intestinal loops in amniotic fluid in children with a GS. This leads to a reduced primary closure rate and a higher number of intraoperative abnormalities and post-operative complications. Aims and Objectives: We analysed abdominal wall defect patients over an 11-year period, aiming to assess the influence of meconium-contaminated amniotic fluid. This study has different objectives to show the consequence of functional outcome of abdominal wall defects (AWD) children in reliance to colour of amniotic fluid, to assess the effect of reduced bowel exposure time to meconium contaminated amniotic fluid on edematous inflammatory thickening of the bowel loops, to show an positively influence in the number of primary AWD closures, to demonstrate a reduced incidence of post-natal complications and to verify a better outcome of OC children because of failing exposure to amniotic fluid. Methods: A retrospective, observational case–control design was used to compare GS (n = 36) and OC (n = 18) children. Physical data, colour of amniotic fluid, pre- and perinatal problems, operative complications and surgical technique, post-operative complications, duration of intensive care unit (ICU) stay, mechanical ventilation, parenteral nutrition, commencement of oral feeding and total hospital stay were collected. Data were analysed with descriptive methods, t-test and non-parametric tests such as Wilcoxon and Kruskal–Wallis were performed in addition to the analysis of variance, including post hoc testing accepting a confidence interval of 95% (P < 0.05) by using IBM SPSS software, version 23 (IBM, Illinois, USA). Results: Rate of meconium-contaminated amniotic fluid is significantly higher in GS compared to OC (P < 0.001), delivery problems such as congenital infections are also significantly higher (P < 0.001), this yields in significantly more bowel loops anomalies and problems during surgery (P < 0.036) but had no significant influence on primary abdominal wall closures rate (P = 0.523). The post-surgical outcome of OC was significantly better as compared to GS. Within the GS, those with swollen intestines had significantly longer ICU stays (P = 0.045) due to extended mechanical ventilation (P = 0.007), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001. Same results were found for the duration of ICU stay (P = 0.008), mechanical ventilation (P = 0.006), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001) in secondary closures as compared to primary abdominal wall closures in the GS group. Conclusions: Worsen functional short-term outcome of GS children was directly addicted to meconium contamination of amniotic fluid due to swollen intestines and because of this more post-surgical problem including significantly extended hospital stays were observed.

The umbilicus is a site of numerous embryopathies involving vessels, urachus, mid gut herniation, anterior abdominal wall defects and congenital cysts. Owing to lack of awareness, umbilical cord hernia (HUC) is often misdiagnosed and underreported, with limited data in the literature. We report an isolated case of congenital HUC and perinatal transection of the sigmoid colon during cord ligature by a midwife in a local health center.A six-day old female neonate presented with discharge of fecal matter through the umbilicus. The clamped cord, became swollen and auto-amputated on day of life three, after which fecal discharge was from the stump was noted. On examination a visible bowel loop containing stool was seen in the umbilical cord. We proceeded with surgical intervention via a small umbilical incision, with findings of transection of the sigmoid colon, no peritoneal contamination, and primary anastomosis was performed. There was event free recovery postoperatively.HUC is poorly understood and often misdiagnosed as omphalocele minor. One should be cognizant of HUC when noting swelling at the base of the cord so as to avoid any inadvertent iatrogenic enterotomy by close umbilical clamping.

Purpose: We compared cases of anemia in gastroschisis versus omphalocele and investigated this clinical question. Methods: A multicenter study of five pediatric surgery departments in southern Japan was planned. Sixty patients were collected between 2011 and 2020, with 33 (gastroschisis: n = 19, omphalocele: n = 14) who met the selection criteria ultimately being enrolled. Anemia was evaluated before discharge and at the first outpatient visit. Results: Despite gastroschisis cases showed more frequent iron administration during hospitalization than omphalocele (p = 0.015), gastroschisis cases tended to show lower hemoglobin values at the first outpatient visit than omphalocele cases (gastroschisis: 9.9 g/dL, omphalocele: 11.2 g/dL). Gastroschisis and the gestational age at birth were significant independent predictors of anemia at the first outpatient visit, (gastroschisis: adjusted odds ratio [OR] 19.00, p = 0.036; gestational age at birth: adjusted OR 0.341, p = 0.028). A subgroup analysis for gastroschisis showed that the ratio of anemia in the 35–36 weeks group (8/10, 80.0%) and the > 37 weeks group (6/6, 100%) was more than in the < 34 weeks group (0/3, 0.0%). Conclusions: Gastroschisis may carry an increased risk of developing anemia compared with omphalocele due to the difference of direct intestinal exposure of amnion fluid in utero.

• Survivability of uncomplicated gastroschisis at two tertiary hospitals was 99.1% in the US and 45.3% in Kenya. • Decreased survival may be from increased bowel exposure to the environment, limited TPN access, and higher rates of infection and sepsis. • Future strategies include improving bowel coverage, patient transport, and access to TPN • Patients in the US can benefit from sutureless closure and early feeding intervention. Gastroschisis is a common birth defect with < 5% mortality in high income countries, but mortality in sub Saharan Africa remains high. We sought to compare gastroschisis management strategies and patient outcomes at tertiary pediatric referral centers in the United States and Kenya. This retrospective chart review examined uncomplicated gastroschisis patients treated at Riley Hospital for Children in Indianapolis, USA (n = 110), and Shoe4Africa Children's Hospital in Eldoret, Kenya (n = 75), from 2010 to 2018. Analyzed were completed using Chi square, Fisher's exact, and independent samples t tests and medians tests at the 95% significance level. Survival in the American cohort was double that of the Kenyan cohort (99.1% vs 45.3%, p < 0.001). Sterile bag use for bowel containment was lower in Kenya (81.3% vs 98.1%, p < 0.001), but silo use was comparable at both institutions (p = 0.811). Kenyan patients had earlier median enteral feeding initiation (4vs 10 days, p < 0.001) and accelerated achievement of full enteral feeding (10vs 23 days, p < 0.001), but none received TPN. Despite earlier feeding, Kenyan patients displayed a higher prevalence of wound infections (70.8% vs 17.1%, p < 0.001) and sepsis (43.9% vs 4.8%, p < 0.001). In Kenya, survivors and non survivors displayed no difference in sterile bag use, hemodynamic stability, all cause infection rates, or antibiotic free hospital days. Defect closure (p < 0.001) and enteral feeding initiation (p < 0.001) were most predictive of survival. Improving immediate response strategies for gastroschisis in Kenya could improve survival and decrease infection rates. Care strategies in the US can center on earlier enteral feeding initiation to reduce time to full feeding. Level of evidence: Level III. [ABSTRACT FROM AUTHOR]

However, patches made from polymers or bio-derived materials may not meet these requirements and lack the bionic characteristics of the abdominal wall.Materials and Methods: In this study, we report a consecutive electrospun method for preparing a double-layer structured nanofiber membrane (GO-PCL/CS-PCL) using polycaprolactone (PCL), graphene oxide (GO) and chitosan (CS). To expand the bio-functions (angiogenesis/reducing reactive oxygen species) of the patch (GO-PCL/NAC-CS-PCL), N-acetylcysteine (NAC) was loaded for the repair of full-thickness abdominal wall defects (2× 1.5cm) in rat model.Results: The double-layered patch (GO-PCL/NAC-CS-PCL) showed excellent mechanical strength and biocompatibility. After 2 months, rats treated with the patch exhibited the desired repair effect with no hernia formation, less adhesion (adhesion score: 1.50± 0.50, P< 0.001) and more collagen deposition (percentage of collagen deposition: 34.94%± 3.31%, P< 0.001).Conclusion: The double-layered nanomembranes presented in this study have good anti-hernia and anti-adhesion effects, as well as improve the microenvironment in vivo. It, therefore, holds good prospects for the repair of abdominal wall defects and provides a promising key as a postoperative anti-adhesion agent.Keywords: abdominal wall defects, graphene oxide, chitosan, N-acetylcysteine, double layer, electrospinning

Background: Pentalogy of Cantrell (PC) is an extremely rare congenital anomaly which was first described in 1985. The incidence of the PC has been reported to vary from 5.5-7.9 cases per million live births. This anomaly involves diaphragmatic pericardial defects, lower sternal defect, intracardiac anomalies, ventral abdominal wall abnormality, and anterior diaphragmatic defect. Considering the number of presented anomalies, PC is classified into three groups of certain, probable, or incomplete pentalogy. Although the etiology of PC is unknown, it has been assumed that abnormalities in intra embryonic mesodermal differentiation formation and migration at around 14-18 days after conception are responsible for the anomalies observed in PC. The prenatal diagnosis of the PC can be made via prenatal two-dimensional or three-dimensional ultrasound. Case report: This case report investigated an Iranian 2-hour-old full-term neonate who was referred to Imam Reza Hospital, Kermanshah, Iran, due to respiratory distress and abdominal wall defect. The patient was finally diagnosed with a probable PC, although his prenatal investigations were considered normal. Conclusion: Although ultrasonography is a widely available tool for prenatal diagnosis of PC, as in our case, the absence of ectopic heart and omphalocele makes the prenatal diagnosis of PC via ultrasonography less possible.

Background: Diastasis recti is a pathology that affects not only the abdominal wall but also the stability of lumbopelvic muscles, consequently altering urinary and digestive functionality. Preaponeurotic endoscopic repair (REPA) is an endoscopic alternative to tummy tuck for the treatment of diastasis. In this study, the outcomes of REPA application by a single surgeon are presented. Methods: A total of 172 patients underwent REPA for the treatment of diastasis recti between August 2017 and December 2019. One hundred twenty-four patients were followed for at least one year. Sixty-three patients responded to a survey on satisfaction and quality of life 12 months after surgery. Results: Three (2.4%) recurrences occurred, of which two occurred in the same patient. The main postoperative complications observed were 12 (9.7%) seromas, 3 (2.4%) haematomas, a single wound infection, 3 (2.4%) cases of skin fold formation, and a case of trophic skin lesion that required negative pressure therapy. Quality of life after surgery, as reported by 63 patients who responded to the survey, was satisfactory. Conclusions: REPA is a safe and effective technique for diastasis recti treatment, representing a valid alternative to abdominoplasty. Since there is no need to access the peritoneal cavity and the mesh is onlay, there are no risks of bowel damage or adhesions between the intestine and prosthesis. [ABSTRACT FROM AUTHOR]

Background: Gastroschisis (GS) and omphalocele (OC) are congenital abdominal wall defects, the main difference between is the direct exposure of intestinal loops in amniotic fluid in children with a GS. This leads to a reduced primary closure rate and a higher number of intraoperative abnormalities and post-operative complications.Aims and Objectives: We analysed abdominal wall defect patients over an 11-year period, aiming to assess the influence of meconium-contaminated amniotic fluid. This study has different objectives to show the consequence of functional outcome of abdominal wall defects (AWD) children in reliance to colour of amniotic fluid, to assess the effect of reduced bowel exposure time to meconium contaminated amniotic fluid on edematous inflammatory thickening of the bowel loops, to show an positively influence in the number of primary AWD closures, to demonstrate a reduced incidence of post-natal complications and to verify a better outcome of OC children because of failing exposure to amniotic fluid.Methods: A retrospective, observational case-control design was used to compare GS (n = 36) and OC (n = 18) children. Physical data, colour of amniotic fluid, pre- and perinatal problems, operative complications and surgical technique, post-operative complications, duration of intensive care unit (ICU) stay, mechanical ventilation, parenteral nutrition, commencement of oral feeding and total hospital stay were collected. Data were analysed with descriptive methods, t-test and non-parametric tests such as Wilcoxon and Kruskal-Wallis were performed in addition to the analysis of variance, including post hoc testing accepting a confidence interval of 95% (P < 0.05) by using IBM SPSS software, version 23 (IBM, Illinois, USA).Results: Rate of meconium-contaminated amniotic fluid is significantly higher in GS compared to OC (P < 0.001), delivery problems such as congenital infections are also significantly higher (P < 0.001), this yields in significantly more bowel loops anomalies and problems during surgery (P < 0.036) but had no significant influence on primary abdominal wall closures rate (P = 0.523). The post-surgical outcome of OC was significantly better as compared to GS. Within the GS, those with swollen intestines had significantly longer ICU stays (P = 0.045) due to extended mechanical ventilation (P = 0.007), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001. Same results were found for the duration of ICU stay (P = 0.008), mechanical ventilation (P = 0.006), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001) in secondary closures as compared to primary abdominal wall closures in the GS group.Conclusions: Worsen functional short-term outcome of GS children was directly addicted to meconium contamination of amniotic fluid due to swollen intestines and because of this more post-surgical problem including significantly extended hospital stays were observed.

Standardized protocols have been shown to improve outcomes in several pediatric surgical conditions. We implemented a multi-disciplinary gastroschisis practice bundle at our institution in 2013. We sought to evaluate its impact on closure type and early clinical outcomes. We performed a retrospective review of uncomplicated gastroschisis patients treated at our institution between 2008–2019. Patients were divided into two groups: pre- and post-protocol implementation. Multivariate logistic regression was used to compare closure location, method, and success. Neonates (pre-implementation n = 53, post-implementation n = 43) were similar across baseline variables. Successful immediate closure rates were comparable (75.5% vs. 72.1%, p = 0.71). The proportion of bedside closures increased significantly after protocol implementation (35.3% vs. 95.4%, p < 0.01), as did the proportion of sutureless closures (32.5% vs. 71.0%, p < 0.01). Median postoperative mechanical ventilation decreased significantly (4 days IQR [3, 5] vs. 2 days IQR [1, 3], p < 0.01). Postoperative complications and duration of parenteral nutrition were equivalent. After controlling for potential confounding, infants in the post-implementation group had a 44.0 times higher odds of undergoing bedside closure (95% CI: 9.0, 215.2, p < 0.01) and a 7.7 times higher odds of undergoing sutureless closure (95% CI: 2.3, 25.1, p < 0.01). Implementing a standardized gastroschisis protocol significantly increased the proportion of immediate bedside sutureless closures and decreased the duration of mechanical ventilation, without increasing postoperative complications.

Objective: Recently, achieving good cosmetic results for patients with gastroschisis has gained popularity, as since the visceral organs can be safely positioned into the abdominal cavity. We aimed to evaluate patient outcomes while focusing on the cosmetic results to contribute to the limited amount of data on this subject in the literature.Methods: From January 2005 to May 2018, patients operated on for gastroschisis in a single institution were evaluated retrospectively.Results: Twenty-two patients with gastroschisis were treated (10 females/12 males). The mean gestational age was 38.2±2.1 weeks. The mean birth weight was 2256.9±418.2 g. Eleven patients were diagnosed prenatally. Five patients had complex gastroschisis. Others presented with necrosis (n=3), perforation (n=3), volvulus (n=1) and jejunal atresia (n=1). Primary closure (n=16) and staged closure (n=6) were performed. Patients needed mechanical ventilation and total parenteral nutrition for 3.7±1.0 days and 24.3±9.7 days, respectively. Enteral feeding was started at 15.9±10.5 days. The duration of hospitalisation was 36.7±13.3 days. Three patients died from sepsis and multi-organ failure.Conclusion:We believe that performing appropriate gastroschisis surgery at the same hospital without transferring to another centre is the main factor in achieving a successful outcome. Good cosmetic results and visceral function were achieved in this study in 86.3% patients.

Purpose: The advantages offered by structured reporting have already been highlighted in the literature. However, there is still no evidence on the validity of this reporting method for the study of abdominal wall defects. This study aims to show the experience of the Trentino Hernia Team (THT) multidisciplinary group in the development and use of a structured CT scan report for the study of abdominal wall defects. Methods: A regional multidisciplinary team (THT group) used a Delphi method to identify and select the most important CT scan parameters needed to describe and stage abdominal wall defects for correct preoperative planning. Based on the selected parameters, a CT scan structured report was worked out and collectively accepted. The first 20 structured reports obtained were individually tested for compilation speed and homogeneity of the data reported by five distinct radiologists. The reports were then evaluated by five different surgeons to test the simplicity of interpretation. Results: We produced a model of a structured report for the study of the abdominal wall defects and tested it in our hospital network on the first 20 reports. The average completion time was 18 min (range 12–25). There was no heterogeneity among the reported data. The reports were analysed by five distinct surgeons to evaluate completeness and simplicity of interpretation. Each surgeon used a Likert scale from 0 to 5 to evaluate each report, producing average scores of 4.8 and 4.1 for completeness and comprehensibility respectively, with a mean combined total score of 8.9 out of 10. Conclusions: Our structured report represents a fundamental tool capable of providing the surgeon with all the measurements of the parameters necessary for correct preoperative planning. At the same time, it is of crucial help for the radiologists representing an easy and fast way to report all the needed parameters using the same standards. [ABSTRACT FROM AUTHOR]

Folic acid (FA) can reduce the risk for selected birth defects other than neural tube defects. We examined whether FA has preventive effects against fetal abdominal wall defects (AWD) in a unique intervention cohort in China. Birth outcomes of 247 831 singleton births from a population-based cohort study with detailed pre-conceptional FA intake information were collected in China in 1993–1996. Information on births at 20 complete gestational weeks, including live births, stillbirths and pregnancy terminations, and all structural birth defects regardless of gestational week were recorded. The birth prevalence of omphalocele, gastroschisis and total fetal AWD was classified by maternal FA supplementation. The prevalence of total AWD was 4·30 per 10 000 births among women who took FA compared with 13·46 per 10 000 births among those who did not take FA in northern China and 6·28 and 5·18 per 10 000 births, respectively, in southern China. The prevalence of omphalocele was 0·54 per 10 000 births among women who took FA compared with 3·74 per 10 000 births among those who did not take FA in northern China and 1·79 and 1·44 per 10 000 births, respectively, in southern China. FA supplementation significantly prevented total AWD in multivariate analysis (relative risk 0·26, 95 % CI 0·11, 0·61) in northern China, although no preventive effect of FA on AWD was observed in southern China. FA supplementation successfully reduced the prevalence of AWD in northern China. [ABSTRACT FROM AUTHOR]

Severe cases of gastroschisis require advanced and multi-staged surgical techniques to cover the abdominal wall defect enabling a secure covering of the eventrated organs. A biodegradable porcine small intestinal submucosa membrane is an attractive material that demonstrates the benefits of bioabsorbable materials. It has been used in children. There are only a few reports of severe gastroschisis treatment with this material. The aim of this work is to present a rare case of a giant upper abdominal wall defect in a newborn with Poland syndrome, treated surgically with a biodegradable membrane. The treatment protected the child from infection and enabled satisfactory healing. The use of the described material was adjusted to the severe general condition of the patient. The biodegradable porcine small intestinal submucosa membrane is a safe material to cover a largesized abdominal defect in newborns. [ABSTRACT FROM AUTHOR]

We report a very rare case of isolated thoracoschisis from the city of Campinas-São Paulo, Brazil. Early management in the NICU allowed gentle reduction of the viscera back to the abdominal cavity with no signs of ischemia or respiratory distress. Complete repair was performed four days later in the operating room, under general anesthesia, using a biocompatible collagen/polyester mesh. Postoperative course was uneventful, the child was discharged from hospital on the 24th postoperative day and outpatient follow-up shows a normal developing child. Clinical and surgical aspects of this rare malformation are discussed.

Application of synthetic or biological meshes is the main therapy for the repair and reconstruction of abdominal wall defects, a common disease in surgery. Currently, no ideal materials are available, and there is an urgent need to find appropriate ones to satisfy clinical needs. Electrospun scaffolds have drawn attention in soft tissue reconstruction. In this study, we developed a novel method to fabricate a composite electrospun scaffold using a thermoresponsive hydrogel, poly (N-isopropylacrylamide)-block-poly (ethylene glycol), and a biodegradable polymer, polylactic acid (PLA). This scaffold provided not only a high surface area/volume ratio and a three-dimensional fibrous matrix but also high biocompatibility and sufficient mechanical strength, and could simulate the native extracellular matrix and accelerate cell adhesion and proliferation. Furthermore, rat adipose-derived stem cells (ADSCs) were seeded in the composite electrospun scaffold to enhance the defect repair and regeneration by directionally inducing ADSCs into endothelial cells. In addition, we found early vascularization in the process was regulated by the hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) pathway. In our study, overexpression of HIF-1α/VEGF in ADSCs using a lentivirus system promoted early vascularization in the electrospun scaffolds. Overall, we expect our composite biomimetic scaffold method will be applicable and useful in abdominal wall defect regeneration and repair in the future.

The number of surgical procedures for abdominal wall defects is increasing, often requiring the insertion of plastic material meshes. Surveillance of patients with inserted plastic meshes requires an accurate determination of the position of the mesh. However, this is a difficult task, depending on the kind of mesh, magnetic resonance imaging (MRI) protocol or consistence of the surrounding tissue (fat, muscle, aponeurosis). The aim of our research was to develop an experimental model to test the ability of MRI to identify the exact position of surgical plastic meshes: polypropylene or polyester. To simulate the placement of a mesh in human body we developed a model built up from two pieces of tissue with dimensions of 40 cm x 20 cm, harvested from a pig with a weight of 120 kg. The meshes were situated for MRI evaluation between the two pieces: abdominal pig muscle respectively suprajacent abdominal pig wall subcutaneous fat, approximately 2 cm high. Five surgical meshes were scanned through six MRI sequences, in view of establishing an optimal MRI scanning protocol and best visible meshes. The MRI scans were evaluated by 5 radiologists with different degrees of training. Our results showed that the experimental model developed by us can be successfully used to test the ability of MRI to visualize different kind of plastic meshes. Also, our experiment has revealed that T1fl2D sequence is the best in highlighting meshes from surrounding tissue, and the best visualized Mesh was number 4, made of polyester. In conclusion, based on our experimental model, we should select a plastic mesh or MRI protocol which will allow an optimal post implantation monitoring. Modern technology of material's fabrication can help to better identify the mesh itself using MRI scanning. [ABSTRACT FROM AUTHOR]

The pathogenesis of omphalocele and gastroschisis is not obvious. Their etiology is disputed. The prevalence and the types of anomalies co‐occurring with omphalocele and gastroschisis are variable in the different series published. The aim of this study was to estimate the frequency and the types of co‐occurring anomalies in cases with gastroschisis and omphalocele. This study was performed in a well‐described population of 387,067 consecutive births between 1979 and 2007. Hundred‐one cases with omphalocele were registered (2.61 per 10,000), 75 (74.3%) had co‐occurring anomalies comprising chromosomal anomalies (28 cases, 27.7%, including 18 trisomy 18), non‐chromosomal syndromes (16 cases, 15.8%, including 3 cases with Beckwith–Wiedemann syndrome, 2 cases with the OEIS sequence, and one case with the Pentalogy of Cantrell complex), and 31 cases, 30.7% with MCA (multiple congenital anomalies). The most common MCA were musculoskeletal (23.5%), urogenital (20.4%), cardiovascular (15.1%), and central nervous (9.1%). Seventy‐one cases of gastroschisis were ascertained (1.83 per 10,000). However, the prevalence increased during the study period. The frequency was highest in the mothers 15–19 years old. Sixteen out of the 71 cases with gastroschisis, (22.5%) had co‐occurring anomalies including 11 cases of MCA and 5 cases with syndromes. To conclude, the frequency and the types of anomalies co‐occurring with omphalocele and gastroschisis are peculiar. Therefore, cases with gastroschisis and omphalocele need to be screened for co‐occurring anomalies. [ABSTRACT FROM AUTHOR]

Abstract Pentalogy of Cantrell (PC) is a rare congenital anomaly characterized by changes in the mesodermal median structures and congenital heart disease, often with a poor prognosis. In 1958, Cantrell et al2 defined the full spectrum of the syndrome with the following anomalies: defects of the anterior diaphragm, of the lower part of the sternum, of the supraumbilical region and the abdominal wall, of the diaphragmatic pericardium, and various intracardiac congenital abnormalities. The present report describes a case of ectopia cordis associated with PC and the importance of the participation of a multidisciplinary team in the treatment of this condition.

Background: Fetoscopic endoluminal tracheal occlusion (FETO) improves lung maturation in severe cases of congenital diaphragmatic hernia (CDH) but it does not ameliorate lung compression by herniated abdominal organs. Surgically opening the fetal abdomen (abdominal decompression [AD]) reduces the intrathoracic pressure by diverting the abdominal organs into the amniotic cavity-a probable causal therapy for lung hypoplasia and pulmonary hypertension in CDH. Open surgical abdominal decompression has been reported: we describe a minimally invasive approach in an ovine model of CDH as a probable fetoscopic intervention. Materials and Methods: Eight fetuses were included, 2 were kept as HEALTHY controls. A CDH (left side, liver down) was created by open fetal surgery at midgestation in 6 fetuses, 2 were taken as CDH controls. Fetoscopic abdominal decompression (fAD) was performed 21 days later in 4 animals. The fetuses were retrieved at the end of gestation and evaluated by lung stereology. Results: fAD led to a near total evacuation of the thoracic cavity in 2 of the 4 animals. Fetuses with CDH had a lower total volume and fraction of alveolar air space, a lower volume fraction of the parenchyma, and an increase of the volume fraction of the alveolar septa and atelectasis, as well as an increased mean thickness of alveolar septa compared with HEALTHY fetuses. Fetuses treated with abdominal decompression showed an improvement of stereological parameters. Conclusions: In spite of relevant limitations (pilot study, small groups, spontaneous closure of the abdominal incision) we were able to demonstrate that abdominal decompression for CDH can be performed by fetoscopy. Our results support the hypothesis of causally improving lung development by abdominal decompression, thus implying increased survival in extreme cases of CDH. A refinement of the fetoscopic techniques and direct comparison to FETO appears warranted. [ABSTRACT FROM AUTHOR]

We present the first trimester prenatal ultrasonography and pathological assessment of a case diagnosed with limb-body wall complex (LBWC) presenting both exenchephaly and a complex thoraco-abdominal wall defect. Ectopia cordis is demonstrated with a movie showing the heart beating outside the body of the fetus after its expulsion. Also, we discuss the pathogenesis and possible etiology of LBWC and associated malformations and we provide an update of the literature of this very rare anomaly. [ABSTRACT FROM AUTHOR]

Background: Pentalogy of Cantrell (PC) is an extremely rare congenital anomaly which was first described in 1985. The incidence of the PC has been reported to vary from 5.5-7.9 cases per million live births. This anomaly involves diaphragmatic pericardial defects, lower sternal defect, intracardiac anomalies, ventral abdominal wall abnormality, and anterior diaphragmatic defect. Considering the number of presented anomalies, PC is classified into three groups of certain, probable, or incomplete pentalogy. Although the etiology of PC is unknown, it has been assumed that abnormalities in intra embryonic mesodermal differentiation formation and migration at around 14-18 days after conception are responsible for the anomalies observed in PC. The prenatal diagnosis of the PC can be made via prenatal two-dimensional or three-dimensional ultrasound. Case report: This case report investigated an Iranian 2-hour-old full-term neonate who was referred to Imam Reza Hospital, Kermanshah, Iran, due to respiratory distress and abdominal wall defect. The patient was finally diagnosed with a probable PC, although his prenatal investigations were considered normal. Conclusion: Although ultrasonography is a widely available tool for prenatal diagnosis of PC, as in our case, the absence of ectopic heart and omphalocele makes the prenatal diagnosis of PC via ultrasonography less possible.

Abdominal wall defects are common clinical diseases, and mesh repair is the standard treatment method. The most commonly used polypropylene (PP) mesh in clinical practice has the advantages of good mechanical properties, stable performance, and effective tissue integration effect. However, direct contact between abdominal viscera and PP mesh can lead to severe abdominal adhesions. To prevent this, the development of a hydrogel-PP composite mesh with anti-adhesive properties may be an effective measure. Herein, biofunctional hydrogel loaded with rosmarinic acid is developed by modifying chitosan and Pluronic F127, which possesses suitable physical and chemical properties and commendable in vitro biocompatibility. In the repair of full-thickness abdominal wall defects in rats, hydrogels are injected onto the surface of PP mesh and applied to intraperitoneal repair. The results indicate that the use of hydrogel-PP composite mesh can alleviate abdominal adhesions resulting from traditional PP mesh implantation by decreasing local inflammatory response, reducing oxidative stress, and regulating the fibrinolytic system. Combined with the tissue integration ability of PP mesh, hydrogel-PP composite mesh has great potential for repairing full-thickness abdominal wall defects., (© 2024 Wiley‐VCH GmbH.)
