Abstract
Pancake kidney is a renal fusion anomaly with only a few reported prenatal diagnoses. Other structural anomalies beyond the urogenital system may also be associated. This study describes a dual anomaly case detected prenatally, comprising of pancake kidney and jejunal atresia. A postnatal abdominal ultrasound confirmed both kidneys were fused in the midline at the aortic bifurcation level, along with a type 3b jejunal atresia. Based on the available limited evidence about pancake kidney, renal functions appear to remain largely preserved and unaffected as in our case according to 6 months of follow-up. However, further investigation is needed to explore any potential association with chromosomal and structural abnormalities in selected cases.

Abstract
BACKGROUND Maldevelopment of the fetal bowel can result in the rare condition of intestinal atresia, which results in congenital bowel obstruction. This report describes a case of prenatal diagnosis of fetal ileal atresia at 22 weeks' gestation. CASE REPORT Here, we present a 24-year old woman who was 22 weeks into her first pregnancy when she underwent routine fetal ultrasound. She was diagnosed with gestational diabetes mellitus. Her body mass index was normal and she had normal weight gain. The ultrasonographic examination performed revealed a hyperechoic bowel and a small dilatation of the bowel. The couple was counselled for possible intestinal atresia and its postnatal implications. At 33 weeks of gestation, polyhydramnios appeared, and the intestinal distension was much more pronounced, with hyperechoic debris in the intestinal lumen (succus-entericus). After birth, surgery was performed and we concluded the patient had type II atresia, which was surgically treated. CONCLUSIONS This report has highlighted the importance of antenatal ultrasound in detecting fetal abnormalities, and has shown that rare conditions such as intestinal atresia can be accurately diagnosed and successfully managed. Surgical correction, if implemented promptly after stabilizing the general condition, can have a relatively good prognosis. Coexisting fetal ileal atresia and gestational diabetes mellitus are rare occurrences, which can make each condition even more difficult to treat.

Abstract
BACKGROUND Congenital malformations of the alimentary tract constitute 5% to 6% of newborn anomalies, with congenital intestinal atresia being a common cause of alimentary tract obstruction. This study explores advanced ultrasound diagnostic possibilities, including 2D, HDlive, HDlive inversion, and HDlive silhouette imaging modes, through the analysis of 3 cases involving duodenal and intestinal obstructions. Congenital malformations of the alimentary tract often present challenges in prenatal diagnosis. The most prevalent defect is congenital intestinal atresia leading to alimentary tract obstruction, with an incidence of approximately 6 in 10 000 births. We focused on advanced ultrasound diagnostic techniques and their applications in 3 cases of duodenal and intestinal obstructions. CASE REPORT Three cases were examined using advanced ultrasound imaging modes. The first patient, diagnosed at week 35 of gestation, revealed stomach and duodenal dilatation. The second, identified at week 32, had the characteristic "double bubble" symptom. The third, at week 31, also had double bubble symptom and underwent repeated amnioreduction procedures. HDlive, HDlive inversion, and HDlive silhouette modes provided intricate visualizations of the affected organs. Prenatal diagnosis of alimentary tract obstruction relies on ultrasound examinations, with nearly 50% of cases being diagnosed before birth. CONCLUSIONS Advanced ultrasound imaging modes, particularly HDlive silhouette, play a crucial role in diagnosing fetal alimentary tract obstruction. These modes offer detailed visualizations and dynamic evaluations, providing essential insights for therapeutic decisions. The study emphasizes the importance of sustained fetal surveillance, a multidisciplinary approach, and delivery in a level III referral center to ensure specialized care for optimal outcomes.

Abstract
OBJECTIVES To investigate whether fetal duodenal tract sections can be visualized in the prenatal ultrasonographic examination. METHODS This study was designed in cross-section. Healthy singleton pregnant women who applied to the perinatology outpatient clinic for second-level ultrasound scanning between September 2020 and February 2021 were included in the study. Demographic information of the participants was obtained and an ultrasound scan was performed. The fetal duodenal tract was evaluated in three sections, including the pylorus. The fetal duodenal tract was differentiated from adjacent organs by its anatomical location, hyperechoic nature, and presence of fluid in the lumen. RESULTS A total of 278 eligible participants between 18 and 22 weeks of gestation were evaluated. While the fetal pylorus was closed in 76.6% of the participants, it was open in 23.4%. Duodenum pars superior, pars descendens, and pars inferior imaging rates were 99.3%, 98.2%, and 95.7%, respectively. It was possible to distinguish these parts from neighboring organs by 99.6%, 100%, and 100%, respectively. While the first, second, and third parts of the duodenum were observed as solid in 42.0%, 58.2%, and 52.2%, respectively, 57.9%, 41.7%, and 47.7% had fluid in the lumen. CONCLUSION The fetal duodenal tract can be viewed with prenatal ultrasonography in pregnant women who are not in a dorsoanterior position. This may make an additional contribution to the diagnosis of duodenal obstructions, which is the most common cause of intestinal atresia in prenatal screening.

Abstract
Conversion of fetal circulation to adult-type occurs immediately after birth but neonates with problems in the development of pulmonary vasculature are prone to revert back to fetal circulation. This phenomenon is known as flip-flop circulation which may be induced perioperatively and as such anesthesiologist are central to its management. We report a case of term neonate planned for repair of duodenal atresia that despite having no respiratory symptom preoperatively developed severe hypoxemia under anesthesia that was even unresponsive to 100% oxygen. The intraoperative hemodynamics of the neonate was managed along with supportive care successfully. A postoperative echocardiogram confirmed the evidence of persistent pulmonary hypertension of the newborn. Keywords: Duodenal atresia; flip flop circulation; neonates; persistent pulmonary hypertension of newborn.

Abstract
RATIONALE Rectal atresia caused by necrotizing enterocolitis (NEC) is a serious and rare complication in children. Magnetic compression anastomosis (MCA) has been effectively applied in children with congenital oesophageal atresia and biliary atresia. Herein, we reported a case of successfully application of MCA in an infant with rectal atresia following NEC. PATIENT CONCERNS A 30 weeks premature birth female fetal infant was transferred to our neonatal intensive care unit due to premature delivery, low birth weight, and neonatal respiratory distress. On postpartum day 11, the infant developed abdominal distension and mucosanguineous feces. This infant was then clinically diagnosed as NEC. She underwent anesthesia and intestinal fistula operation on postpartum day 11 because of NEC. DIAGNOSIS After 3 months, radiographic examination revealed rectal atresia and stricture. INTERVENTIONS This infant was successfully treated with MCA following a cecum-rectal anastomosis and ileocecal valve was reserved. OUTCOMES On postoperative day 9, she passed the 2 magnets per rectum. In addition, there were no difficult defecation or fecal incontinence or other short-term complications. After the 7-month follow-up, the patient had an excellent clinical outcome. LESSONS MCA is a feasible and effective method for treating rectal atresia in infants.

Abstract
Mitchell-Riley syndrome (MRS) is caused by recessive mutations in the regulatory factor X6 gene (RFX6) and is characterised by pancreatic hypoplasia and neonatal diabetes. To determine why individuals with MRS specifically lack pancreatic endocrine cells, we micro-CT imaged a 12-week-old foetus homozygous for the nonsense mutation RFX6 c.1129C>T, which revealed loss of the pancreas body and tail. From this foetus, we derived iPSCs and show that differentiation of these cells in vitro proceeds normally until generation of pancreatic endoderm, which is significantly reduced. We additionally generated an RFX6HA reporter allele by gene targeting in wild-type H9 cells to precisely define RFX6 expression and in parallel performed in situ hybridisation for RFX6 in the dorsal pancreatic bud of a Carnegie stage 14 human embryo. Both in vitro and in vivo, we find that RFX6 specifically labels a subset of PDX1-expressing pancreatic endoderm. In summary, RFX6 is essential for efficient differentiation of pancreatic endoderm, and its absence in individuals with MRS specifically impairs formation of endocrine cells of the pancreas head and tail.

Abstract
Intrauterine intussusception is a rare but evident cause of intestinal atresia and is usually detected intraoperatively. We report on a term neonate who presented to the Department of Paediatric Surgery, Sabah Women and Children's Hospital, Malaysia with delayed passage of meconium and intestinal obstruction, wherein the lower contrast showed a claw sign. This was a good clue that this neonate had intrauterine intussusception and this suspicion was confirmed upon laparotomy. We found an ileo-ileal intussusception causing ileal atresia, requiring resection and primary anastomosis.

Abstract
Duodenal atresia concomitant with type-A esophageal atresia (DA + TA-EA) is rare. A pronounced enlargement of a closed loop of the upper gastrointestinal tract serves as an early clue for its prenatal detection. We describe an atypical case of DA + TA-EA in which the dilatation of the upper gastrointestinal tract remained mild. Ultrasonographic examination at 28 weeks of gestation showed mild polyhydramnios. Subsequent detailed sonographic and magnetic resonance imaging studies revealed a mildly enlarged stomach and duodenum that resembled a "double bubble," mild ascites, and polydactyly of the right thumb. Fetal abdominal circumference measurements were within normal range. A female neonate born at 36 weeks gestation did not show abdominal distension. DA + TA-EA was diagnosed based on clinical characteristics and X-ray studies of the neonate; the diagnosis was confirmed by surgery. Duodenoduodenostomy and gastrostomy in the first week of life and esophagoesophagostomy at six months of age were performed with satisfactory results, and the infant developed well. Prominent and/or increasing C-shaped fluid collection in the upper abdomen is a highly useful diagnostic sign for DA + TA-EA, but it is not applicable for all fetuses with this disease. Physicians should bear this caveat in mind to avoid diagnostic delays and initiate prompt postnatal therapy.

Abstract
RATIONALE AND OBJECTIVES The purpose of this study was to critically appraise and compare the diagnostic performance of imaging modalities that are used for the diagnosis of upper and lower gastrointestinal (GI) tract obstruction in neonates and infants. METHODS A focused clinical question was constructed and the literature was searched using the patient, intervention, comparison, outcome method comparing radiography, upper GI contrast study, and ultrasound in the detection of upper GI tract obstruction such as duodenal atresia and stenosis, jejunal and ileal atresia, and malrotation and volvulus. The same methods were used to compare radiography and contrast enema in the detection of lower GI tract obstruction such as meconium plug syndrome, meconium ileus, Hirschsprung disease, and imperforate anus. Retrieved articles were appraised and assigned a level of evidence based on the Oxford University Centre for Evidence-Based Medicine hierarchy of validity for diagnostic studies. RESULTS There were no sensitivities/specificities available for the imaging diagnosis of duodenal atresia or stenosis, jejunal or ileal atresias, meconium plug, and meconium ileus or for the use of cross-table lateral radiography for the diagnosis of rectal pouch distance from skin in imperforate anus. The retrieved sensitivity for the detection of malrotation on upper GI contrast study is 96%, and the sensitivity for the diagnosis of midgut volvulus on upper GI contrast study is 79%. The retrieved sensitivity and specificity for the detection of malrotation with volvulus on ultrasound were 89% and 92%, respectively. The retrieved sensitivity and specificity for the detection of Hirschsprung disease on contrast enema were 70% and 83%, respectively. The retrieved sensitivity of invertogram for the diagnosis of rectal pouch distance from skin in imperforate anus is 27%. The retrieved sensitivities of perineal ultrasound and colostography for the diagnosis of rectal pouch distance from skin in imperforate anus were 86% and 100%, respectively. CONCLUSIONS There is limited evidence for the imaging diagnosis of duodenal atresia and stenosis, jejunal and ileal atresias, meconium plug, meconium ileus, and imperforate anus, with recommended practice based mainly on low-quality evidence or expert opinion. The available evidence supports the use of upper GI contrast study for the diagnosis of malrotation and volvulus, with ultrasound as an adjunct to diagnosis. Contrast enema is useful in the investigation of suspected Hirschsprung disease, but a negative study does not outrule the condition. Colostography is the investigation of choice for the work-up of infants with complex anorectal malformations before definitive surgical repair.

Abstract
BACKGROUND Gastroschisis complicates 1 in 2000 births and is readily identifiable during prenatal ultrasound scans. Outcomes in fetuses that are affected by gastroschisis vary widely from stillbirth or neonatal death to uncomplicated surgical correction, which makes prenatal counseling challenging. OBJECTIVE The goal of our study was to identify sonographic markers that are associated with perinatal death and morbidity that include significant bowel injury, necrotizing enterocolitis, and the need for bowel resection in fetuses with gastroschisis. STUDY DESIGN We identified a cohort of fetuses that were diagnosed with gastroschisis from 2003-2014. Sonographic markers that were reviewed included growth restriction, abdominal circumference, oligohydramnios, bowel dilation, and gastric bubble characteristics. We evaluated these markers both at diagnosis and near delivery. Four adverse perinatal outcomes were assessed: perinatal death, necrotizing enterocolitis, need for bowel resection, and a composite of significant bowel injury, which included a diagnosis of bowel atresia or necrosis at the time of surgical exploration. Logistic regression was performed to calculate odds ratios and 95% confidence intervals for each marker and outcome. RESULTS One hundred seventy-seven patients were identified, and 154 of these patients met inclusion criteria after exclusions for delivery <24 weeks gestation, other associated anomalies, lethal karyotype, or lost to follow-up evaluation. Markers at the time of diagnosis (median gestational age, 21 weeks [25th,75th interquartile range, 19, 24 weeks]) that were associated with perinatal death were abdominal circumference <5th percentile (odds ratio, 5.56; 95% confidence interval, 1.25-24.76), abnormal gastric bubble (odds ratio, 11.20; 95% confidence interval, 2.15-58.33), and abnormal stomach location (odds ratio, 17.1; 95% confidence interval, 2.99-97.85). An abnormal stomach location (odds ratio, 5.53; 95% confidence interval, 1.03-29.72) before delivery was associated with perinatal death. Gastric dilation before delivery (odds ratio, 4.36; 95% confidence interval, 1.10-17.34)] was associated with the need for bowel resection. CONCLUSION Early sonographic markers of increased perinatal mortality rates include abdominal circumference <5th percentile and an abnormal gastric bubble.

Abstract
OBJECTIVE The accuracy of prenatal ultrasound examination in detecting jejunal and ileal atresia has been reported in the literature to be highly variable, at 25-90%. The aim of this systematic review was to evaluate the accuracy of prenatal ultrasound in detecting non-duodenal small bowel atresia (ND-SBA). METHODS MEDLINE, EMBASE and The Cochrane Library, including The Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effects (DARE) and The Cochrane Central Register of Controlled Trials (CENTRAL), were searched electronically. The overall detection rate of jejunal or ileal atresia using ultrasound was reported. The accuracy of using polyhydramnios and dilated loops of bowel as diagnostic signs was also explored. RESULTS Sixteen studies involving 640 fetuses were included in this review. The detection rate of ND-SBA by prenatal ultrasound was highly variable, with values ranging from 10 to 100%, with an overall prediction of 50.6% (95% CI, 38.0-63.2%). When analyzed separately, the detection rates of jejunal and ileal atresia were 66.3%, (95% CI, 33.9-91.8%) and 25.9% (95% CI, 4.0-58.0%), respectively. Both dilated loops of bowel and polyhydramnios as diagnostic signs for ND-SBA provided a low overall detection rate. CONCLUSIONS The diagnostic performance of prenatal ultrasound in identifying ND-SBA is extremely variable. Large studies are needed in order to identify objective and combined criteria for the diagnosis of these anomalies.

Abstract
OBJECTIVES To estimate the association between antenatal bowel dilation and postnatal small-bowel atresia in fetal gastroschisis and to establish a threshold at which the risk of adverse neonatal outcome increases. METHODS This was a retrospective cohort study of singleton gestations with an antenatal diagnosis of gastroschisis seen in our ultrasound unit from 2001 to 2010. We reviewed stored images from the last ultrasound examination before delivery, blinded to postnatal diagnoses and outcomes. Fetal intra- and extra-abdominal bowel dilation (IABD and EABD, respectively) and bowel-wall thickness were measured. Previously published definitions of bowel dilation, including > 6, > 10, > 14 and > 18 mm, were evaluated for association with the primary outcome of bowel atresia. The optimal threshold to define fetal bowel dilation was determined by evaluating the significance of association as well as test performance characteristics. RESULTS Of 109 consecutive patients with fetal gastroschisis, there were four cases of intrauterine fetal demise and three neonatal deaths. Of the 94 live births with complete outcome data, 39 (41.5%) had measurable IABD. There were 14 (14.9%) cases of bowel atresia. Using a threshold of > 14 mm, IABD was significantly associated with an increased risk for bowel atresia (relative risk, 3.1 (95% CI, 1.2-8.2)) with a sensitivity of 57.1%, specificity of 75.0%, positive predictive value of 28.6% and negative predictive value of 90.9%. IABD > 14 mm was also associated with a significantly longer stay in neonatal intensive care unit. There was no significant association between EABD and bowel atresia at any of the thresholds evaluated. CONCLUSION IABD > 14 mm is associated with an increased risk for postnatal bowel atresia in fetal gastroschisis. This finding may be useful in counseling patients regarding the anticipated postnatal course for their neonate.

Abstract
Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly distended bowel loops and small amount of fetal ascites.

Abstract
PURPOSE To compare various gestational ages and thresholds for diagnosing bowel dilatation in fetuses with gastroschisis and to evaluate the prognostic value of bowel dilatation for predicting postnatal bowel atresia and neonatal outcomes. MATERIALS AND METHODS This was a retrospective observational study conducted from March 1997 to September 2009 that included 78 pregnancies with fetal gastroschisis. The predictive value of prenatal bowel dilatation for neonatal bowel atresia and postnatal complications was investigated in three subgroups: those with bowel dilatations ≥ 10 mm at a gestational age < 27 + 0 weeks, ≥ 10 mm at a gestational age < 30 + 0 weeks and ≥ 18 mm at a gestational age ≥ 30 weeks. RESULTS Prenatally, 6 %, 81 % and 13 % of the bowel malformations were identified in the first, second and third trimesters, respectively. There were three stillbirths and three neonatal deaths, and the mean gestational age at delivery was 35.4 weeks (range 31 + 4 to 41 + 6). Bowel atresia was significantly correlated with prenatal bowel dilatation in all three subgroups. Bowel dilatations of ≥ 10 mm before 30 + 0 gestational weeks achieved the best performance in predicting bowel atresia, with a sensitivity of 89 % (8 / 9) and a specificity of 79 % (30 / 38). A prenatal bowel diameter ≥ 10 mm through 30 completed weeks was also the best predictor of a prolonged neonatal hospital stay ≥ 8 weeks (sensitivity = 61.1, 11 / 18, p = 0.002). CONCLUSION Fetuses with isolated gastroschisis successfully underwent postnatal surgery in most cases (93.2 %), except for one termination, one intrauterine death and 3 cases of neonatal death. A fetal bowel dilatation > 10 mm before 30 + 0 weeks had the highest predictive value for postnatal bowel complications.

Abstract
PURPOSE We correlate severe bowel damage in gastroschisis to the rare intrauterine event of narrowing of the abdominal wall around the protruding intestines. We describe this "closing gastroschisis" as a distinct entity. Prenatal ultrasound findings as gastric or bowel dilation were compared to the postnatal findings in order to find markers for an early in utero diagnosis of closing gastroschisis. Early diagnosis could prompt timely delivery to save the compromised bowel and avoid short gut syndrome. MATERIALS AND METHODS We documented the pre- and postnatal course of our patients with gastroschisis from 2007 to 2009. Closing gastroschisis was suspected antenatally and confirmed postnatally. We identified 5 out of 18 patients showing closure of the abdominal wall with varying degrees of bowel damage. Prenatal ultrasound findings were correlated to the postnatally confirmed extent of intestinal damage. RESULTS We could not find consistent ultrasound markers for prenatal diagnosis of closing gastroschisis. In prenatal ultrasound three patients presented significant gastric dilation and then experienced severe courses postnatally due to segmental gut necrosis. One of these three died and the other two developed short gut syndrome. In one case progressive intraabdominal loop dilation with simultaneous shrinking of the extraabdominal loops occurred corresponding to closing gastroschisis with segmental midgut necrosis. CONCLUSION Closing gastroschisis must be seen as a special form of gastroschisis. Extended intestinal damage is often life-threatening. In longitudinal observation dynamics of fetal ultrasound findings can lead to the diagnosis of closing gastroschisis. Progressive intraabdominal loop dilation is always highly suspicious and must lead to close follow-up and timely delivery.

Abstract
OBJECTIVES To evaluate the sonographic abdominal findings in children with suspected upper gastrointestinal disease, establish indications for sonography and describe the gastrointestinal disease patterns that can be evaluated by ultrasound. DESIGN Descriptive prospective study. SETTING Kenyatta National Hospital and Department of Diagnostic Imaging and Radiation Medicine, University of Nairobi. SUBJECTS Fifty-six children who presented with vomiting and suspected upper gastrointestinal disease. Age range was from six days to 12 years with mean age of one year five months. Seventy seven percent were two years and below. RESULTS Of the 56. children, six were normal on sonography; 18 (32.1%) had intussusception, 16 (28.6%) gastroesophageal reflux, seven (12.5%) pyloric stenosis, four appendicitis, three jejunal/ileal atresia and two enteric duplication cysts. All the children with pyloric stenosis were male. The male: female ratio for intussusception and GER was 1.5:1 and 1.6:1 respectively. The most common clinical presentation in children found to have intussusception was palpable abdominal mass, and few of them presented with bloodstained stool. More than two thirds of the children with gastro-oesophageal reflux presented with complications of recurrent pneumonia and failure to thrive. The sonographic findings correlated with fluoroscopy for GER except in two children where sonography was found to be more sensitive. The sonographic findings correlated with surgical outcome for pyloric stenosis, intussusception,jejunal/ ileal atresia and enteric duplication cysts. CONCLUSION Trans-abdominal sonography has a definite role in investigating the child suspected to have upper gastrointestinal disease and should be considered as the initial imaging modality, instead of fluoroscopy, thereby avoiding or limiting the use of ionising radiation. Findings in this study confirm that ultrasound is an accurate, reliable and rapid screening method to evaluate the causes of upper gastrointestinal disease in children.
