Abstract
BACKGROUND AND AIM Heterotaxy syndrome, being right atrial isomerism (RAI) or left atrial isomerism (LAI), often presents with Congenital Heart Disease (CHD). Intestinal abnormalities, including malrotation are common. We assessed the spectrum of gut abnormalities and their impact on medium-term outcome in a cohort of patients with fetal and postnatal diagnoses of heterotaxy syndrome. METHODS We reviewed the cardiology records of heterotaxy syndrome patients from two centres, regarding the presence of CHD, time for cardiac intervention, presence of gastrointestinal abnormalities, and type/time of surgery. A questionnaire about gastrointestinal status was sent to patients <18 years old. Kaplan-Meier curves were derived for survival data and freedom from intervention. RESULTS Data were included for 182 patients (49 RAI and 133 LAI) of 247 identified. Questionnaires were sent to 77 families and 47 replied. CHD was present in all RAI and 61.7% of LAI cases. Thirty-eight patients had abdominal surgery (20.9%), similar for RAI and LAI (20.4% versus 21%, p> 0.99): Ladd procedure in 17 (44.7%), non-Ladd in 12 (31.5%), and both procedures in 9 (23.7%). Ten-year freedom from Ladd procedure for all was 86% for the whole cohort (RAI = 87%; LAI = 85%, p = 0.98). Freedom from any gastrointestinal surgery at 10 years was 79% for the whole cohort (RAI = 77%; LAI = 80%, p = 0.54). Ten-year freedom from cardiac surgery was 31% for the whole cohort (RAI = 6%; LAI = 43%, p < 0.0001). CONCLUSIONS In our cohort, one in five patients required abdominal surgery, mostly in their first year of life, similar for RAI and LAI. Between 1 and 10 years of follow-up, the impact of gastrointestinal abnormalities on outcome was minimal. Medium term survival was related to CHD.

Abstract
OBJECTIVE The aim of the study was to evaluate whether fetal ultrasound could determine bronchial isomerism and distinguish left isomerism from right isomerism. METHODS We identified 110 healthy fetuses and 28 fetuses with isomerism. The outer angle between the tracheal midline and the inner margin of the bronchus is measured. The bronchial angles and the ratio of left/right bronchial angle were used to differentiate bronchial morphology and confirm the presence of bronchial isomerism in pathological cases. RESULTS The normal angles of the left and right bronchi were 146.98° (95% CI, 145.15-147.81°) and 167.37° (95% CI, 166.30-168.44°), separately. The cutoff bronchial angle of 156.5° was used to distinguish left bronchus from right bronchus. The bronchial isomerism could be identified in all pathological cases by autopsy and bronchial-atrial concordance occurred in 27 pathological cases (96.4%). In 21 pathological cases, the bilateral bronchial angle was <156.5 versus >156.5 differentiated left from right isomerism, respectively. The ratio of the left/right bronchial angle of >0.935 identified 92.9% (26/28) of all pathological cases, with a sensitivity of 89.7%. CONCLUSIONS Fetal ultrasound can detect the bronchial morphology and the presence of bronchial isomerism in fetuses with isomerism according to bronchial angles and the ratio of left/right bronchial angle.

Abstract
Human laterality disorders comprise a group of diseases characterized by abnormal location (situs) and orientation of thoraco-abdominal organs and vessels across the left-right axis. Situs inversus totalis is mirror image reversal of thoraco-abdominal organs/great vessels. Situs ambiguus, better known as heterotaxy, is abnormal arrangement of thoraco-abdominal organs across the left-right axis excluding situs inversus totalis. Heterotaxy, also referred to as atrial or atrial appendage isomerism, is characterized by abnormal location of left-sided or right-sided organs with loss of asymmetry of normally paired asymmetric organs. It is associated with a variety of anomalies involving the heart, great vessels, lungs and intra-abdominal organs. Right and left atrial isomerism are associated with multiple complex congenital cardiac and vascular anomalies, many of which are lethal when untreated. Isomerism may also affect the lungs, spleen, liver, gall bladder, and intestines. Innovative surgical therapy of heterotaxy/isomerism has reduced early mortality and markedly improved long-term prognosis.

Abstract
To appreciate congenital heart disease fully, a detailed understanding of the anatomical presentation, as well as the physiology, is required. This is often introduced at an advanced stage of training. Professor Anderson has been influential in the Clinical Anatomy Intercalated BSc programme at the University of Birmingham, in particular in his teaching on Sequential Segmental Analysis. This article describes the experiences of the latest cohort of students on this programme, who undertook varying research projects using the Birmingham Cardiac Archive, with the guidance of Professor Anderson. The projects outlined include various aspects of isomerism, encompassing both the cardiac and abdominal manifestations, as well as details of congenitally corrected transposition of the great arteries and prenatally diagnosed right aortic arch and double arch. These studies all aimed to increase the knowledge base of their respective cardiac malformations and provide a basis for further research.

Abstract
Situs anomalies are rare structural defects affecting 0.01% of general population. They present with multisystem structural defects mostly involving cardiovascular, respiratory and GI systems. Situs abnormality with presence of multiple spleen is termed as left atrial isomerism with anatomical and structural differences to its countertype situs ambiguous with asplenia (right atrial isomerism). In this case report, we present an adult case of situs ambiguous anomaly which was diagnosed incidentally during laparoscopic cholecystectomy. The patient had enlarged left lobe of liver, multiple splenules on right side, malrotated small and large gut, interrupted inferior vena cava with azygos continuation, and bilateral bilobed lungs. It is concluded that variations in situs ambiguous cases differ and a single description is not possible. It is crucial to reveal these variations by using imaging modalities and being aware of them prior to surgery and invasive intervention to prevents the possible risks and complications.

Abstract
Introduction Heterotaxy syndrome/ isomerism is characterized by an abnormal symmetry of the viscera that are normally dissimilar due to abnormal lateralization of thoracic and abdominal viscera and is frequently associated with complex cardiac anomalies. Isomerism may be of right or left. Materials and methods This article describes the morphological characteristics of heterotaxy and suggests an approach in evaluating the spectrum of abnormalities associated with this syndrome. This study is based on 12 cases diagnosed on antenatal ultrasound as heterotaxy syndrome. Results of the examinations were re-evaluated and compared by fetal autopsy. Result Based on the following echocardiographic criteria, a diagnosis of left isomerism was made if there was viscerocardiac heterotaxy associated with an interruption of inferior vena cava or with bilateral finger-like atrial appendages or if it was associated with heart block. If there was evidence of viscerocardiac heterotaxy with complex cardiac anomalies then it was diagnosed as right atrial isomerism or visceral heterotaxy syndrome. We diagnosed 6/12 as left isomerism and rest of the cases as right isomerism/visceral heterotaxy syndrome. In Autopsy we evaluated visceral situs and morphology of the lungs and the main bronchi, the state of the liver, spleen, bowel, and the precise anatomy of the heart and confirmed 4/12 as left isomerism 4/12 as right isomerism and two cases as visceral heterotaxy syndrome (VHS). Rest of the two cases were included in the study despite missing autopsy data, as the combination of abnormal situs with interrupted inferior vena cava, and cardiac malformation allowed a diagnosis of left isomerism with high probability. Conclusion In this study, we aimed to find common features of heterotaxy syndrome on prenatal ultrasound as well as on fetal autopsy. This syndrome should be accurately diagnosed in the prenatal period in order to allow appropriate counseling of parents.

Malrotation is not associated with adverse outcomes after cardiac surgery in patients with heterotaxy syndrome. J Pediatr Surg 2018; 53:1494-1498. [PMID: 29453132 DOI: 10.1016/j.jpedsurg.2018.01.008] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2017] [Revised: 12/18/2017] [Accepted: 01/15/2018] [Indexed: 11/21/2022]
Abstract
BACKGROUND Patients with heterotaxy syndrome (HS) often have asymptomatic malrotation. There is a lack of consensus regarding the management of these patients, particularly in patients with complex congenital heart disease (CHD). We sought to describe the prevalence of malrotation and incidence of volvulus in a population of patients with complex CHD and to identify the impact of malrotation on morbidity and mortality following cardiac surgery. METHODS We performed a retrospective review of all patients with HS and complex CHD who required cardiac surgery in the first year of life at a single center between October 1995 and September 2015. Malrotation was diagnosed by abdominal imaging or by direct inspection during abdominal surgery. Demographic data was collected along with details of hospitalization following cardiac and GI surgeries. Descriptive analysis along with appropriate hypothesis testing was conducted to evaluate the results. RESULTS We identified 49 patients with HS, 42 with single ventricle anatomy and 7 with biventricular anatomy. Of the 49 patients, 29 (59%) were diagnosed with malrotation, 6 (12%) had normal intestinal rotation, and 14 (29%) had no evaluation of intestinal rotation. The prevalence of malrotation in the population who underwent abdominal imaging was 29 out of 35 (83%). There was no difference in survival following cardiac surgery between patients with malrotation and those with unknown or normal intestinal anatomy. Comparing patients with malrotation and patients with normal or unknown intestinal rotation, there was also no difference in surrogate markers of morbidity. Of the 29 patients with known malrotation, only 2 patients (7%) underwent therapeutic Ladd procedures and 19 (65%) underwent prophylactic Ladd procedures. CONCLUSIONS We conclude that the outcomes following cardiac surgery for patients with HS are not impacted by the presence of malrotation. Furthermore, we also found that the incidence of volvulus in the studied group is low. Given these findings, and the understanding that patients with HS and significant CHD are frequently tenuous and high risk surgical candidates, we do not believe performing prophylactic Ladd procedures is warranted.

Abstract
OBJECTIVES The main aim of this systematic review was to evaluate the prevalence and type of associated anomalies in fetuses with heterotaxy diagnosed prenatally on ultrasound; the perinatal outcome of these fetuses was also studied. METHODS An electronic search of MEDLINE, EMBASE and CINAHL databases was performed. Only studies reporting the prenatal diagnosis of isomerism were included. Outcomes observed included associated cardiac and extracardiac anomalies, fetal arrhythmia, abnormal karyotype, type of surgical repair and perinatal mortality. The analysis was stratified according to the type of heterotaxy syndrome (left (LAI) or right (RAI) atrial isomerism). Meta-analyses of proportions were used to combine data. Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies. RESULTS Sixteen studies (647 fetuses) were included in the analysis. Atrioventricular septal defect was the most common associated major cardiac anomaly found both in fetuses with LAI (pooled proportion (PP), 59.3% (95% CI, 44.0-73.7%)), with obstructive lesions of the right outflow tract occurring in 35.5% of these cases, and in fetuses with RAI (PP, 72.9% (95% CI, 60.4-83.7%)). Fetal arrhythmias occurred in 36.7% (95% CI, 26.9-47.2%) of cases with LAI and were mainly represented by complete atrioventricular block, while this finding was uncommon in cases with RAI (PP, 1.3% (95% CI, 0.2-3.2%)). Abnormal stomach and liver position were found, respectively, in 59.4% (95% CI, 38.1-79.0%) and 32.5% (95% CI, 11.9-57.6%) of cases with LAI, and in 54.5% (95% CI, 38.5-70.1%) and 45.9% (95% CI, 11.3-83.0%) of cases with RAI, while intestinal malrotation was detected in 14.2% (95% CI, 2.5-33.1%) of LAI and 27.1% (95% CI, 7.9-52.0%) of RAI cases. Hydrops developed in 11.8% (95% CI, 2.9-25.6%) of fetuses diagnosed prenatally with LAI. Biventricular repair was accomplished in 78.2% (95% CI, 64.3-89.4%) of cases with LAI, while univentricular repair or palliation was needed in 17.0% (95% CI, 9.7-25.9%); death during or after surgery occurred in 26.8% (95% CI, 4.6-58.7%) of LAI cases. Most children with RAI had univentricular repair and 27.8% (95% CI, 15.5-42.1%) died during or after surgery. CONCLUSIONS Fetal heterotaxy is associated with a high prevalence of cardiac and extracardiac anomalies. Approximately one quarter of fetuses with heterotaxy died during or after surgery. Abnormal heart rhythm, especially heart block, is common in fetuses with LAI, while this finding is uncommon in RAI. Biventricular repair was common in LAI while univentricular repair was required in the majority of children affected by RAI. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE (1) Is screening of intestinal rotational anatomy obligatory in "asymptomatic" patients with heterotaxy? (2) Does detection of an anomaly warrant surgical correction? SUMMARY OF BACKGROUND DATA Heterotaxy is an abnormal arrangement of thoraco-abdominal viscera across a left-to-right axis. Intestinal rotational anomalies are frequent among patients with heterotaxy, but debate exists as to whether they are benign in nature, requiring careful observation alone, or if surgical correction is warranted to prevent obstruction or midgut volvulus. METHODS A systematic review [according to PRISMA guidelines] was conducted using CINAHL, EMBASE, Medline, and Cochrane Databases. Article quality was assessed using MINORS criteria. Conference proceedings and unpublished data were screened additionally. RESULTS Nineteen studies met the eligibility criteria but reporting was adequate for 9. All were observational studies. These included a total of 414 patients managed expectantly, that is, "asymptomatic patients" in whom no intestinal rotation screening was undertaken (group A), 191 cases in whom screening was performed routinely (group B), and 92 patients considered "symptomatic" of potential rotational anomalies and therefore underwent imaging or laparotomy (group C). In group A, 1 patient developed symptoms attributable to malrotation in whom laparotomy confirmed the diagnosis (0.24%). Among groups B and C, 151 had Ladd's operations (53%) and 14 cases of malrotation with obstruction or volvulus were described (4.9%), of which 2 "symptomatic patients" died before laparotomy. Overall surgical complication rate was 17% with 30-day mortality rate of 2.6% to 4.6%. CONCLUSION The evidence base for screening "asymptomatic" patients is weak especially considering the life-limiting comorbidities.

Single institution experience with the Ladd’s procedure in patients with heterotaxy and stage I palliated single-ventricle. World J Clin Pediatr 2016; 5:319-324. [PMID: 27610349 PMCID: PMC4978626 DOI: 10.5409/wjcp.v5.i3.319] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 04/01/2016] [Accepted: 06/03/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate and describe our current institutional management protocol for single-ventricle patients who must undergo a Ladd’s procedure.
METHODS: We retrospectively reviewed the charts of all patients from January 2005 to March 2014 who were diagnosed with heterotaxy syndrome and an associated intestinal rotation anomaly who carried a cardiac diagnosis of functional single ventricle and were status post stage I palliation. A total of 8 patients with a history of stage I single-ventricle palliation underwent Ladd’s procedure during this time period. We reviewed each patients chart to determine if significant intraoperative or post-operative morbidity or mortality occurred. We also described our protocolized management of these patients in the cardiac intensive care unit, which included pre-operative labs, echocardiography, milrinone infusion, as well as protocolized fluid administration and anticoagulation regimines. We also reviewed the literature to determine the reported morbidity and mortality associated with the Ladd’s procedure in this particular cardiac physiology and if other institutions have reported protocolized care of these patients.
RESULTS: A total of 8 patients were identified to have heterotaxy with an intestinal rotation anomaly and single-ventricle heart disease that was status post single ventricle palliation. Six of these patients were palliated with a Blaylock-Taussig shunt, one of whom underwent a Norwood procedure. The two other patients were palliated with a stent, which was placed in the ductus arteriosus. These eight patients all underwent elective Ladd’s procedure at the time of gastrostomy tube placement. Per our protocol, all patients remained on aspirin prior to surgery and had no period where they were without anticoagulation. All patients remained on milrinone during and after the procedure and received fluid administration upon arrival to the cardiac intensive care unit to account for losses. All 8 patients experienced no intraoperative or post-operative complications. All patients survived to discharge. One patient presented to the emergency room two months after discharge in cardiac arrest and died due to bowel obstruction and perforation.
CONCLUSION: Protocolized intensive care management may have contributed to favorable outcomes following Ladd’s procedure at our institution.

Abstract
OBJECTIVE To assess the role of screening and prophylactic surgery for intestinal rotational abnormalities (IRAs) in asymptomatic patients with heterotaxy. STUDY DESIGN PubMed, Embase, and Cinahl were searched electronically to determine the overall incidence of IRAs in heterotaxy; the detection rate of IRAs associated with screening; the incidence of midgut volvulus in patients without screening; and the incidence of morbidity and mortality after prophylactic and emergency Ladd procedures. Relevant data were computed with a meta-analysis of proportions. Between-study heterogeneity was assessed with the I(2) statistic. RESULTS From 276 papers identified, 24 studies with a total of 1433 patients with heterotaxy were included for systematic review. No randomized study was identified. True incidence of IRA in heterotaxy could not be ascertained through meta-analysis. In patients who underwent screening, the incidence of IRA was 58%. Acute midgut volvulus occurred in 5.8% of those who did not undergo screening. Postoperative mortality after Ladd procedure mainly was associated with cardiac insufficiency, and overall it was significantly greater in the emergency group compared with the prophylactic group (18% vs 5.6%). The complication rate also was greater in case of emergency vs prophylactic abdominal surgery (27% vs 16%); adhesional small bowel obstruction was the most common complication overall (6%). CONCLUSION The screen-detected incidences of IRA and acute midgut volvulus were significantly greater in heterotaxy than the normal population. Prophylactic Ladd procedure was associated with less morbidity and mortality compared with emergency surgery. A long-term prospective randomized trial is needed to define the indication for screening and prophylactic treatment of IRA in heterotaxy.

Abstract
We report the findings present in 49 postmortem specimens from patients with so-called heterotaxy, concentrating on those found in the extracardiac systems of organs. Also known as bodily isomerism, we suggest that it is important to segregate the syndromes into their isomeric subtypes to be able to make inferences regarding likely extracardiac and intracardiac findings to allow for proper surveillance. We demonstrate that this is best done on the basis of the atrial appendages, which were isomeric in all the hearts obtained from the specimens available for our inspection. The abdominal organs do not demonstrate isomerism, and they show variable features when compared to the isomeric atrial appendages.

Abstract
BACKGROUND The association of heterotaxy with intestinal rotation anomalies is well described. However debate exists with regard optimal management notably should 'asymptomatic' bowel rotation anomalies undergo operation? The present study therefore sought to determine: (1) the risk(s) of volvulus in patients diagnosed with heterotaxy and (2) define morbidity associated with operation for 'asymptomatic' anomalies in a fragile patient cohort with co-existent congenital heart disease. METHODS Medical case record reviews of ALL heterotaxy patients born during January 1993-December 2013 and attending a UK paediatric centre were analyzed. RESULTS Of a total of 92 patients, 16 (17.4%) cases underwent foregut imaging studies. Three examinations were performed in 'symptomatic' patients. Twelve studies reported 'abnormal anatomy' with only five patients undergoing surgical correction. No complication(s) were recorded after Ladd's operation to correct defects. A single fatality occurred within 30 days postoperatively from cardiac failure. In 87 patients in whom Ladd's operation was not undertaken, no single patient developed intestinal volvulus (median length of follow-up 27.2 months, total 446.1 person years). CONCLUSION This study strongly supports a 'watchful waiting' policy for heterotaxy patients. Many children who ultimately die from heart disease may avoid unnecessary abdominal surgery.

Abstract
BACKGROUND Heterotaxy patients' hearts may or may not be suitable for biventricular repair depending on anatomy. Even in the subset that are amenable to surgical septation, cardiac anatomy may present multiple difficulties in achieving a satisfactory repair. However, it is also well known that heterotaxy patients are not ideal candidates for univentricular repair. METHODS From 2007 until 2012, a total of 20 patients (11 male) with heterotaxy syndrome underwent biventricular repair (left atrial isomerism: 10 and right atrial isomerism: 10) in our center. Their median age at surgery was 40 (range: 3-108) months. Ten patients had dextrocardia. Eleven patients presented with bilateral superior vena cava, three with inferior vena cava (IVC) draining into left atrium, and six with IVC interruption with azygos or hemiazygos continuation. Anomalous pulmonary venous drainage was present in eight patients. One had a common atrium. Atrioventricular septal defect (AVSD) occurred in nine (complete AVSD in seven) patients. Eight patients had double outlet right ventricle (DORV), one had d-transposition of great arteries (d-TGA), and two had congenitally corrected transposition of the great arteries (CC-TGA). Prior palliative procedures included pulmonary artery banding in three patients and left modified Blalock-Taussig shunt in one patient. Complex intra-atrial baffle constructions were required in all patients to direct pulmonary and systemic venous inflow to the appropriate ventricle. Complete AVSDs were corrected using two-patch technique. Intraventricular tunnel repair was done for DORV. Combined atrial and arterial switch was required to rectify abnormal connections in a child with congenitally corrected transposition with normal pulmonary valve, while a Rastelli + Senning was needed in two children with CC-TGA with pulmonary atresia (n = 1) and double outlet of the right ventricle (n = 1). RESULTS Major early postoperative complications included intestinal gangrene in four patients for which they underwent bowel resection. Two of these patients could not be salvaged. One patient required coiling of aortopulmonary collateral for early postoperative pulmonary hemorrhage. Two patients needed a tracheostomy for prolonged mechanical ventilatory support. Five patients had a pacemaker implanted for complete heart block. There were no instances of atrial baffle stenosis. Median follow-up was 27 (range: 2-46) months. There was one late death secondary to pneumonia. CONCLUSIONS Satisfactory survival outcomes can be achieved in heterotaxy patients who undergo hemodynamically acceptable biventricular repair. Borderline ventricular hypoplasia and trivial atrioventricular valve regurgitation should not be considered as discouraging factors in anatomically suitable heterotaxy patients as it is possible to adopt a two-stage repair in such patients to achieve biventricular repair at a later stage. Anticipating a higher incidence of conduction problems and gut malrotation preemptively can help reduce the morbidity.

Abstract
BACKGROUND Children with heterotaxy syndrome and intestinal rotational anomalies (IRA) are at risk for midgut volvulus and ischemia. Controversy exists regarding risks and benefits of prophylactic Ladd procedures. The purpose of this study is to assess the impact of Ladd procedures on adverse events for children with heterotaxy and IRA. METHODS A retrospective cohort study using the Pediatric Health Information System (PHIS) database was performed. All children with heterotaxy and IRA admitted at age ≤ 30 days and discharged between 1/1/2004 and 1/1/2011 were included with a minimum 2-year follow-up period. The primary outcome was major morbidity, defined as a composite variable for intestinal obstruction/volvulus, ischemia, or resection, or inhospital mortality. Univariable and multivariable analyses were performed. RESULTS There were 325 patients who met the inclusion criteria, including 92 (28%) patients with single ventricles. Mean gestational age was 38.0 ± 2.1 weeks and birth weight was 3.1 ± 0.6 kg. Ladd procedure was performed during initial hospitalization on 188 (58%) children. In multivariable analyses, Ladd procedure on initial hospitalization was associated with a 2.2 times increased odds of adverse events on subsequent admissions (95% CI 1.3-4.0, p = 0.007). CONCLUSIONS Ladd procedure is associated with increased odds of adverse events for children with heterotaxy and IRA.

Abstract
PURPOSE OF REVIEW At present, there is a debate as to the management of malrotation in pediatric patients. This review highlights recent literature including the role of laparoscopy, and the management of asymptomatic patients with and without congenital cardiac disease. RECENT FINDINGS Symptomatic patients are still recommended to undergo open Ladd's procedure. Laparoscopic Ladd's procedure in asymptomatic patients confers a shorter time to tolerating feeds, shorter length of stay, and a decreased rate of bowel obstruction and other complications. It may, however, carry a higher risk of postoperative volvulus. Diagnostic laparoscopy is recommended in asymptomatic patients in whom the diagnosis is uncertain on upper gastrointestinal imaging. Asymptomatic patients with congenital heart disease may be managed with initial observation or operation, based upon individualized risk benefit assessment. If an elective Ladd's procedure is performed, it should take place after palliative cardiac operations have resulted in stable cardiac function. Screening upper gastrointestinal studies in heterotaxy patients may be unnecessary as the reported rates of volvulus in recent studies are low. SUMMARY Laparoscopic Ladd's procedure may be an acceptable alternative to an open procedure for asymptomatic patients. Observation of asymptomatic patients with congenital cardiac disease is a reasonable alternative in selected patients.

Abstract
Variant anatomy may be challenging at retrieval, with failure to identify variance being associated with organ damage, particularly vascular damage. On implantation, some variants demand nonstandard techniques of reconstruction or implantation. This review covers the common and less common anatomical variants of the liver, kidney and pancreas, and gives guidance as to how they may be managed during organ retrieval and implantation.

Abstract
PURPOSE Controversy remains regarding the management of the asymptomatic heterotaxy syndrome (HS) patient with suspected intestinal rotational abnormalities. We evaluated the outcomes for our HS population to identify frequency of malrotation and identify characteristics of children who might benefit from expectant management. METHODS After IRB approval, a retrospective review of all patients treated for HS at a large tertiary care children's hospital between January 2008 and June 2012 was performed. For the purpose of this paper, malrotation was defined as an operative note that described the presence of Ladd's bands and a narrow mesentery. RESULTS Thirty-eight patients with HS were identified, including 18 who underwent abdominal exploration. Left atrial isomerisation (LAI) was identified in 13 individuals, and right atrial isomerisation (RAI) was noted in 25. The rate of surgical intervention did not vary between the 2 groups (54%). Malrotation was found in 8 patients: one with LAI and 7 with RAI. This difference in incidence was statistically significant (p=0.04). CONCLUSION These data suggest that the direction of atrial isomerisation influences the likelihood of true malrotation, where RAI patients are more likely to be malrotated. Given the inherent risk of surgery on this medically fragile patient population, surgeons should consider expectant management for asymptomatic LAI patients.

Abstract
OBJECTIVE To report our experiences in the prenatal diagnosis of atrial isomerism and postnatal outcomes. METHODS A total of 80 fetuses prenatally diagnosed with atrial isomerism were retrospectively analyzed between 1999 and 2011 at a single institution. RESULTS Of 43 fetuses with prenatally diagnosed right atrial isomerism (RAI), 40 cases were analyzed. The diagnostic accuracy was 93%. The main intracardiac anomalies in RAI were atrioventricular septal defect (AVSD), abnormal pulmonary venous connection, bilateral superior vena cava (BSVC), and pulmonary atresia. Among 28 live births, three infants were lost to follow up, and the overall survival rate was 60%. Of 37 fetuses with prenatally diagnosed left atrial isomerism (LAI), 35 were evaluated. The diagnostic accuracy was 97%. The main intracardiac anomalies in LAI were ventricular septal defect, BSVC, AVSD, double outlet right ventricle, and bradyarrhythmia. Among seven patients with bradyarrhythmia, only one showed a complete atrioventricular block. All fetuses had an interrupted inferior vena cava with azygous continuation. The overall survival rate was 90%. CONCLUSION Our study confirms the previous findings of fetal atrial isomerism. We also demonstrates a much lower prevalence of AVSD and complete heart block in LAI and a better survival rate in RAI. Although the postnatal outcomes for RAI were worse than those for LAI, successful postnatal surgery with active management improved the survival rate.

Abstract
PURPOSE Abnormalities of intestinal rotation (IRA) are commonly associated with heterotaxy syndrome (HS). There is controversy whether asymptomatic infants with HS require screening for IRA and if present, whether a prophylactic Ladd procedure is indicated. The objective of this study is to determine institutional practice across North America in the management of asymptomatic infants with HS and IRA. METHODS We performed an international, multi-institutional web based survey to examine current practice and opinions in the management of IRA in HS patients. RESULTS Overall response rate was 30%. Of physicians surveyed, 84% believe that HS patients should be screened for IRA in the neonatal period. 61% of general surgeons, 50% of cardiovascular surgeons and 45% of cardiologists feel that all patients with HS and an asymptomatic IRA should have a prophylactic Ladd procedure. 55% of physicians stated they would be comfortable with conservative management for patients with HS and asymptomatic IRA. CONCLUSIONS The risk of midgut volvulus, morbidity and mortality from elective procedures and cardiovascular prognosis must be considered prior to an elective Ladd procedure on asymptomatic HS patients. There are practice variance among sub-specialists caring for these patients, a lack of expert consensus, and a paucity of evidence-based data for IRA in this population.

Abstract
Heterotaxy syndrome (HS) is a complex disorder involving thoracic and abdominal asymmetries. Congenital heart disease is often accompanied by an intestinal rotation abnormality (IRA) that may predispose to bowel ischemia and infarction. There is controversy in the literature whether asymptomatic infants with HS must be screened for IRA and, if present, whether a prophylactic Ladd procedure should be performed. We performed a retrospective chart review of all patients who underwent a Ladd procedure from January 2007 to December 2010 at Stollery Children's Hospital, Edmonton, Canada. Twenty-nine patients underwent a Ladd procedure, 22 without HS but with symptomatic malrotation and 7 with HS and asymptomatic malrotation. Asymptomatic HS patients had a complication rate of 57 % after a prophylactic Ladd procedure compared with a complication rate of 9 % in the symptomatic non-HS population. The management of asymptomatic IRA in patients with HS remains controversial. We suggest that HS patients be screened for IRA and that asymptomatic patients be managed conservatively.

Abstract
OBJECTIVE To evaluate whether dogs undergoing splenectomy had an increased risk of gastric dilatation-volvulus (GDV), compared with a control group of dogs undergoing enterotomy. DESIGN Retrospective case-control study. ANIMALS 219 dogs that underwent splenectomy for reasons other than splenic torsion (splenectomy group; n = 172) or enterotomy (control group; 47) without concurrent gastropexy. PROCEDURES Medical records were reviewed for information on signalment, date of surgery, durations of surgery and anesthesia, reason for splenectomy, histopathologic findings (if applicable), whether gastropexy was performed, duration of follow-up, and date of death (if applicable). Follow-up information, including occurrence of GDV, was obtained via medical records review and a written client questionnaire. RESULTS Reasons for splenectomy included splenic neoplasia, nonneoplastic masses, infarction, traumatic injury, and adhesions to a gossypiboma. Incidence of GDV following surgery was not significantly different between dogs of the splenectomy (14/172 [8.1 %]) and control (3/47 [6.4%]) groups. Median time to GDV for the 17 affected dogs was 352 days (range, 12 to 2,368 days) after surgery. Among dogs that underwent splenectomy, sexually intact males had a significantly higher incidence of GDV (4/16) than did castrated males and sexually intact or spayed females (10/156). Incidence of GDV among sexually intact male dogs did not differ between groups. CONCLUSIONS AND CLINICAL RELEVANCE Results did not support a recommendation for routine use of prophylactic gastropexy in dogs at the time of splenectomy. Other patient-specific risk factors should be assessed prior to recommending this procedure.

Abstract
Dextrocardia was known in the 17th century and was 1 of the first congenital malformations of the heart to be recognized. Fifty years elapsed before Matthew Baillie published his account of complete transposition in a human of the thoracic and abdominal viscera to the opposite side from what is natural. In 1858, Thomas Peacock stated that "the heart may be congenitally misplaced in various ways, occupying either an unusual position within the thorax, or being situated external to that cavity." In 1915, Maude Abbott described ectopia cordis, and Richard Paltauf's remarkable illustrations distinguished the various types of dextrocardia. In 1928, the first useful classification of the cardiac malpositions was proposed, and in 1966, Elliott et al's radiologic classification set the stage for clinical recognition. The first section of this review deals with the 3 basic cardiac malpositions in the presence of bilateral asymmetry. The second section deals with cardiac malpositions in the presence of bilateral left-sidedness or right-sidedness. Previous publications on cardiac malpositions are replete with an arcane vocabulary that confounds rather than clarifies. Even if the terms themselves are understood, inherent complexity weighs against clarity. This review was designed as a guided tour of an unfamiliar subject.

Abstract
PURPOSE Heterotaxy syndrome (HS) patients often present with congenital heart disease and intestinal malrotation. Controversy exists regarding the management of these patients. Risk of midgut volvulus, morbidity from elective operations, and overall prognosis must be weighed when considering a Ladd procedure on asymptomatic HS/intestinal malrotation patients. METHODS This is a retrospective review comparing HS and non-heterotaxy syndrome (NHS) patients undergoing a Ladd procedure at Children's Hospital Boston (Mass) from January 1997 to September 2007. RESULTS Thirty-one HS and 51 NHS patients were identified. After a Ladd procedure, HS patients remained in the hospital 12.9 days, had a 9.7% risk of small bowel obstruction, and a 9.7% in-hospital mortality. If allowed to develop abdominal symptoms, 27% of HS patients with intestinal malrotation had a midgut volvulus at surgery. Intra-HS group comparison demonstrated longer hospital stays in symptomatic patients (P = .01). Mortality was greater in the HS than NHS patients, but deaths were related to cardiac disease and not to the Ladd procedure. CONCLUSIONS Elective Ladd procedures are well tolerated by HS patients. Given the risk of midgut volvulus and in light of improved survival beyond infanthood, once identified, HS patients with asymptomatic malrotation should be offered a prophylactic Ladd procedure.

Abstract
Failure to establish normal left-right body axis (LRA) formation during embryogenesis results in heterotaxis, a multi-malformation syndrome. We report on a 20-year-old young woman who presented to the emergency room with upper abdominal pain. On chest X-ray, dextrocardia was noted. Ultrasound was inconclusive. Barium studies demonstrated non-rotation of the intestine. Magnetic resonance imaging (MRI) of the abdomen confirmed heterotaxis with abnormal arrangement of abdominal organs and vasculature. This is the first radiographic description of LRA in MRI. It provides a unique contribution to the wide morphological variety of lateralization defects in a single examination within 15 min and without the risks of ionizing radiation. In addition, a literature overview over the genetic aspects, broad morphological spectrum, and possible therapeutic consequences is given.

Abstract
Polysplenia syndrome, defined as the presence of multiple spleens of almost equal volume, is a rare condition involving congenital anomalies in multiple organ systems. We report this anomaly in a 41-year-old female who underwent a left lateral sectionectomy due to recurrent cholangitis and impacted left lateral duct stones. Polysplenia syndrome with preduodenal vein was diagnosed preoperatively by computed tomography (CT) and surgery was done safely. Although the polysplenia syndrome with preduodenal portal vein (PDPV) in adult is rarely encountered, surgeons need to understand the course of the portal vein and exercise caution in approaching the biliary tract.

Abstract
INTRODUCTION Gastric volvulus is an important cause of nonbilious emesis that must be recognized early to ensure a good outcome. We reviewed 7 cases from our institution, Children's Healthcare of Atlanta (Egleston campus). In addition, we reviewed all gastric volvulus cases in children published to date in the English literature to draw general conclusions about the presentation and treatment of this unusual disease. METHODS An electronic literature search was performed to find all published cases of pediatric gastric volvulus. The care of all children from January 2002 to December 2007 who were treated for gastric volvulus was also reviewed. RESULTS There have been 581 cases of gastric volvulus in children published in English between 1929 and 2007. Of these, 252 were acute and 329 were chronic cases. The most common presentation of acute gastric volvulus is in a child <5 years old with nonbilious emesis, epigastric distention, and abdominal pain. Acute gastric volvulus is often associated with deformities of adjacent organs. Definitive diagnosis is made with upper gastrointestinal studies, and definitive therapy requires repair of associated defects and anterior fixation of the stomach to the abdominal wall. The most common presentation of chronic volvulus is in an infant <1 year old with emesis, epigastric distention, feeding difficulties, and growth failure. Treatment may be medical or surgical depending on the underlying etiology of the volvulus. CONCLUSIONS Acute gastric volvulus is a potentially life-threatening occurrence with a good outcome when treated in a timely fashion. Chronic volvulus may be more difficult to recognize. The common features of acute and chronic gastric volvulus described in this review should assist pediatric health care providers in promptly diagnosing and treating this disease.

Abstract
OBJECTIVE Abnormalities of intestinal rotation (AIR) are seen in association with congenital heart disease and heterotaxy syndrome. The prevalence of these abnormalities and recommendations for management are unclear. Our objective was to determine the prevalence of screening for AIR by elective imaging among our group and prophylactic vs. emergent surgical intervention for AIR in patients with congenital heart disease and heterotaxy syndrome. METHODS From October 1988 through October 2000, we identified 74 patients with congenital heart disease and heterotaxy syndrome, 44 (59%) asplenia, 30 (41%) polysplenia. Abdominal imaging was performed in 34 patients (45%). Twenty-four (32%) were found to have AIR. Of 34 patients imaged, 22 (65%) were found to have AIR. Two patients not imaged were found to have AIR: one at autopsy, and the other, incidentally during other abdominal surgery. Because imaging was performed based on individual cardiologist's practice style that did not change over the period of the study and rarely secondary to symptoms, it is likely that the prevalence of AIR in the patients that were not electively imaged would be similar. RESULTS There was no statistical difference in the presence of AIR between asplenic (34%[15/44]) and polysplenic (30%[9/30]) patients. Of the 22 patients imaged with AIR, 18 underwent Ladd procedure. Five of 12 imaged patients without AIR were found to have other significant gastrointestinal pathologies requiring intervention including gastrostomy tube placement for reflux (3), duodenal web (1), and biliary atresia (1). Of the 40 patients who were not pre-emptively imaged, none suffered acute obstruction solely secondary to AIR. However, in 2 patients intestinal obstruction was suspected and subsequently discovered by imaging and/or laparotomy due to other intestinal anomalies. CONCLUSIONS AIR is common among patients with heterotaxy syndrome and congenital heart disease. We recommend that patients with congenital heart disease and heterotaxy syndrome have routine elective abdominal imaging of their gastrointestinal tract at birth as part of their evaluation.

Abstract
Gastric volvulus was first described by Berti in 1966. Whereas acute gastric volvulus is very rare, chronic gastric volvulus on the other hand is being diagnosed with increasing frequency. This is attributed to the liberal use of barium meal for the evaluation of infants and children with repeated attacks of vomiting and recurrent chest infection. This report describes our experience in the management of 36 infants and children with acute and chronic gastric volvulus. Their medical records were retrospectively reviewed for: age at diagnosis, sex, symptomatology, diagnosis, treatment and outcome. There were 22 males and 14 females. Their ages at presentation ranged from 1 week to 2.5 years (mean 6.7 months). Their symptomatology included repeated attacks of vomiting (30 patients), recurrent chest infection and asthma like symptoms (6 patients), failure to thrive (6 patients), chocking with feeds (3 patients), loose bowel motion (3 patients) and apnoea attack (1 patient). Two presented acutely with intrathoracic gastric volvulus. One of them had recurrent left diaphragmatic hernia while the other had a large paraesophageal hernia. The remaining patients had chronic intraabdominal gastric volvulus. Radiologically, all had organo-axial gastric volvulus except one who had mesenterico-axial gastric volvulus and 33 (97%) of them had demonstrable gastroesophageal reflux. Eleven were treated conservatively because their symptoms were mild to moderate and settled. The two patients with intrathoracic gastric volvulus underwent reduction of the contents, repair of the defect and anterior gastropexy. The remaining patients underwent gastropexy, both fundal and anterior. Intraoperatively, two were found to have diaphragmatic hernia, nine had mobile (non-fixed) spleen, and eight showed mobile stomach with lax ligaments. Post-operatively, all did well and showed good improvement with disappearance of their symptoms and increase in weight. Acute gastric volvulus is very rare. Prompt clinical suspicion and radiological assessment are essential to treat this life-threatening condition. Chronic gastric volvulus on the other hand is more common but under diagnosed. It should be included in the differential diagnosis of infants and children with repeated attacks of chest infection, vomiting and failure to thrive. Barium meal should form part of their investigations. The treatment of chronic gastric volvulus depends on their symptomatology. Those with mild to moderate symptoms should be treated conservatively, while those with persistent and severe symptoms should undergo anterior (to the abdominal wall) and fundal (to the diaphragm) gastropexy without fundoplication.

Abstract
Gastric volvulus is an uncommon entity that may rapidly progress to infarction and necrosis of the stomach. We herein report the case of a 67-year-old man with acute gastric volvulus in association with wandering spleen. Following a reduction of the volvulus with a nasogastric tube, laparoscopic gastropexy was performed. Pediatric cases of gastric volvulus and a concurrent wandering spleen have been described, but to the best of our knowledge, no adult cases have previously been reported.

Abstract
PURPOSE Intestinal rotation abnormalities and complex congenital heart disease associated with heterotaxia coexist. Despite the risk for midgut volvulus, performing a Ladd procedure for asymptomatic malrotation with heterotaxia remains to be controversial because the presumed risk for postoperative complications is thought to exceed the benefits of the operation. The purpose of this study was to review the incidence of complications after a Ladd procedure in asymptomatic patients with heterotaxia to guide recommendations for this patient population. METHODS The medical records of all patients with heterotaxia who underwent a Ladd procedure for asymptomatic malrotation between 1984 and 2004 were reviewed. Type of cardiac disease, postoperative complications, and survival were recorded. RESULTS Twenty-two patients (9 boys and 13 girls) with heterotaxia underwent an elective Ladd procedure after their medical stabilization or surgical correction or palliation of their cardiac anomaly. Of these patients, 19 were younger than 1 month at the time of the operation. The remaining 3 patients underwent the operation when they were between 2 and 5 months old. Three of the 22 patients (14%) developed postoperative intestinal obstruction: lysis of adhesions was performed in 1 patient; another patient required a staged bowel resection for a closed loop obstruction; and yet another patient had recurrent midgut volvulus 4 years after an incomplete initial Ladd procedure. All patients survived the initial and secondary procedures. Four deaths, all more than 1 month after the surgery, occurred as sequelae of the underlying cardiac anomaly. Length of follow-up ranged from 1 to 17 years. CONCLUSIONS We report on a 14% risk of postoperative bowel obstruction after an elective Ladd procedure, as compared with a small but significant incidence of midgut volvulus in patients with malrotation in the setting of complex congenital heart disease. Our results support the conclusion that an elective Ladd procedure at a time of relative cardiac stability for selected patients with heterotaxia has an acceptably low morbidity and should be considered to prevent midgut volvulus.

Abstract
A male infant weighting 2970 g with total situs inversus, polysplenia, malrotation, duodenal stenosis, and complex cardiac anomalies, was admitted to our hospital. At 4 days of age, he underwent surgery that revealed a blood vessel passing over the duodenum from the mesenterium to the porta hepatis. A loose overbridging duodenoduodenostomy was performed to prevent compression of the vessel. The cardiac anomalies were corrected, and he could eat unrestricted diets. At the age of 1 year and 3 months, a 3-dimensional computed tomographic scan demonstrated that the vessel on the duodenum was the superior mesenteric vein (SMV), and it formed the portal vein with the splenic vein at the porta hepatis. Further, the scan revealed no compression of the SMV at the anastomosis. Doppler ultrasonography revealed a normal portal blood flow of 118.6 mL/min. This report describes the junction between the SMV and the splenic vein in a patient who had the SMV passing over the duodenum from the mesenterium. Correctly, patients previously diagnosed with a preduodenal portal vein could have a preduodenal SMV. The loose overbridging duodenoduodenostomy had advantages not only in passage of the anastomosis but also in maintenance of the portal blood flow for the congenital duodenal obstruction with the preduodenal SMV.

Abstract
PURPOSE OF REVIEW Children with heterotaxia often have abnormalities of intestinal rotation, some of which may predispose to midgut volvulus. This review summarizes the literature and proposes an individualized approach to the patient based on symptoms and findings on gastrointestinal imaging. RECENT FINDINGS This report reviews the types of heterotaxia syndromes and the debate surrounding the optimal management of the associated intestinal rotational abnormalities. Recent publications suggest that not all rotational abnormalities predispose to volvulus and that the natural history of rotational abnormalities in asymptomatic patients with heterotaxia is relatively benign. On the basis of these findings, an algorithm for the management of intestinal rotational abnormalities is proposed. SUMMARY Malrotation and midgut volvulus is a life-threatening complication. Children with heterotaxia and symptoms suggestive of a proximal intestinal obstruction require urgent investigation and surgical treatment. Asymptomatic children require close clinical follow-up and urgent investigation of gastrointestinal symptoms.

Abstract
The looping events that establish left-right asymmetries in the vertebrate gut tube are poorly understood. Retinoic acid signaling is known to impact left-right development in multiple embryonic contexts, although its role in asymmetric digestive organ morphogenesis is unknown. Here, we show that the genes for retinaldehyde dehydrogenase (RALDH2) and a retinoic acid hydroxylase (CYP26A1) are expressed in complementary patterns in the Xenopus gut during looping. A late-stage chemical genetic assessment reveals that agonists and antagonists of retinoid signaling generate abnormal gut looping topologies, digestive organ heterotaxias, and intestinal malrotations. Accessory organ deformities commonly associated with intestinal malrotation in humans, such as annular pancreas, pancreas divisum, and extrahepatic biliary tree malformations, are also induced by distinct retinoid receptor agonists. Thus, late-stage retinoic acid signaling is likely to play a critical role in asymmetric gut tube morphogenesis and may underlie the etiology of several clinically relevant defects in the digestive system.

Abstract
OBJECTIVE To evaluate whether abnormal atrial morphology, which is well recognized in autopsy series, is detectable by fetal echocardiographic examination of the four-chamber view, and can therefore be utilized to differentiate left from right isomerism in heterotaxy syndromes. METHODS This study was a retrospective review of 30 cases with prenatally diagnosed heterotaxy syndromes. Ultrasound video recordings and still images were reviewed with respect to atrial morphology in the four-chamber view. In 25 cases the morphology of both atria was sufficiently well visualized on the recordings to be evaluated and only these were included in the study. RESULTS Two types of atrial morphology were distinguished in our cohort: a sickle-shape with the tip pointing laterally and apically, and a blunt shape resembling the usual atrial appearance in the four-chamber view. Nineteen out of the 25 cases (76%) presented with isomerism of the atria in the four-chamber view. Thirteen had bilateral sickle-shaped atrial morphology, all associated with left isomerism. Six had bilateral blunt-shaped atrial morphology, all associated with right isomerism. The atria of the remaining six cases were not isomeric, the right atrium being sickle-shaped and the left blunt-shaped. Five of the latter cases were associated with left and one with right isomerism. CONCLUSIONS The majority of prenatally diagnosed heterotaxy syndromes seem to present with isomeric atrial morphology in the four-chamber view. In these cases a differentiation between left and right isomerism can be based on the two distinct types of atrial morphology. This may further enhance the prenatal differentiation of these syndromes.

Abstract
OBJECTIVE Despite a reported association between hiatal hernia in patients with heterotaxy syndrome, the clinical significance has remained unclear. Based on large patient cohorts, this study specifically aimed at defining the implication of hiatal hernia in patients with right isomerism. METHODS From 1994 to 2002, 143 patients were identified as having right isomerism. Among them, 119 received ultrafast computed tomography (CT) to determine the presence of hiatal hernia as well as any cardiovascular anomalies. RESULTS Hiatal hernia was found in 17 patients (seven females and 10 males, 14.3%). The upper gastrointestinal (GI) series in six patients confirmed the diagnosis of hiatal hernia in all and revealed severe gastro-oesophageal reflux in four. The most common symptom of hiatal hernia was vomiting (47%), followed by recurrent bronchiolitis or pneumonia (41.2%) and upper gastrointestinal bleeding (11.8%). Three patients with hiatal hernia underwent fundoplication for medically refractory vomiting. Seven patients were found to have midgut malrotation (5.9%), and four of these had both hiatal hernia and malrotation. Pulmonary atresia was closely associated with the presence of hiatal hernia (p=0.02). One patient with hiatal hernia died suddenly at 6 mo. However, overall mortality was similar between those patients with hiatal hernia and those without. CONCLUSIONS The incidence of hiatal hernia was considerably high in patients with right isomerism, especially in those with pulmonary atresia, and it is this that may have led to vomiting and recurrent airway infections. While an association between sudden death and hiatal hernia may well exist, this does require further clarification.

Abstract
BACKGROUND Heterotaxia syndrome involves multiple anomalies, including cardiac malformations and intestinal rotation abnormalities. Most authors recommend routine radiological evaluation, with laparotomy and Ladd procedure if a rotation abnormality is found. AIMS To determine if routine radiological screening is necessary, and if there is a group of children that can safely be managed expectantly. METHODS Retrospective chart review of all children with heterotaxia syndrome from 1968 to 2002. RESULTS Complete data were available for 177 patients. Twenty five (14%) had neonatal gastrointestinal symptoms (feeding intolerance, vomiting). Eleven of these had gastrointestinal contrast studies, of which seven were abnormal and led to surgery. Of the 152 asymptomatic neonates, nine had radiological screening and six of these were abnormal. Only one was thought to have a narrow based mesentery, but did not undergo surgery due to cardiac disease. There were no intestinal complications on follow up in this group. The other 143 asymptomatic children did not undergo radiological screening and were closely followed. Four subsequently developed gastrointestinal symptoms and had contrast studies; only one of these had malrotation and underwent a Ladd procedure. Of the remaining 139 patients who remained asymptomatic, 60 (43%) died of cardiac disease and none developed intestinal symptoms or complications related to malrotation on follow up. CONCLUSION Asymptomatic children with heterotaxia syndrome have a low risk of adverse outcome related to intestinal rotation abnormalities. Routine screening may not be necessary as long as close follow up is done, and prompt investigation is performed for those that develop gastrointestinal symptomatology.

Abstract
Gastric volvulus is a rare cause of acute abdomen in children. Usually it is associated with defects such as diaphragmatic hernia, hiatal hernia, eventration, and paralysis of the diaphragm. We report an extremely rare case presenting with acute intractable vomiting and abdominal distention. Passage of a nasogastric tube relieved the symptoms. A history of the ingestion of a large bolus of chewing gum and a suboptimal contrast study were misleading, and there was a delay in diagnosis of 3 days. Later, repeat upper GI fluoroscopy with contrast medium identified mesenteroaxial volvulus of the stomach. Exploratory laparotomy additionally revealed a wandering spleen. Derotation of the stomach with anterior gastropexy was performed. To our knowledge, wandering spleen in association with gastric volvulus has been mentioned only three times before in the literature.

Abstract
Acute gastric volvulus is an infrequent entity. Management is surgical. Diagnosis frequently is delayed because of the non-specific nature of presenting symptoms. The authors report a case of acute gastric volvulus diagnosed by computed tomography in a 92 year old woman that was confirmed at surgery. The pathophysiology, classification and different presentations of this entity are briefly reviewed. CT findings suggesting gastric volvulus are reviewed as well.

Abstract
INTRODUCTION Spleen preservation by autotransplantation is indicated in cases of injuries which result with conquassation or total devascularization of this organ. MATERIAL AND METHODS Thirty dogs, experimental group, had multiple, devascularized spleen injuries and underwent splenectomy and splenic autotransplantation. The same number of animals were treated by primary splenectomy (control group). Seventy five days later, animals from both groups were exposed to pneumococcal sepsis--by intravenous inoculation of sublethal pneumococcal doses, in order to estimate the immunity of lienal implants and compare the mortality rate between these two groups. RESULTS Positive hemoculture, as well as logarithmic increase of diplococci in blood samples was established in all 60 animals. Higher mortality rate and significantly higher pneumococcal growth was established in control, compared to experimental group. CONCLUSION These results point to the important role of lienal implants in total immunity and advantage of autotransplantation compared to conventional splenectomy, in cases of most severe and nonreconstructibile spleen injuries.

Abstract
OBJECTIVE To assess the accuracy of fetal echocardiography in the prenatal diagnosis of cardiosplenic syndromes and the spectrum of associated anomalies. METHODS This was a retrospective survey of fetuses in our databases over a period of 10 years with postnatally confirmed prenatal diagnosis of cardiosplenic syndromes. RESULTS In 32 of 35 fetuses the prenatal diagnosis of cardiosplenic syndromes was confirmed postpartum. Twenty-two fetuses had left isomerism. Their main prenatal ultrasound features were interrupted inferior vena cava (n = 21), complete atrioventricular septal defect (n = 15), viscerocardiac heterotaxy (n = 15), persistent bradyarrhythmia (n = 12) and fetal hydrops or nuchal edema (n = 12). Twelve pregnancies were terminated, two fetuses were stillborn and eight infants survived. Ten fetuses had right isomerism. Their main sonographic features were juxtaposition of the descending aorta and inferior vena cava (n = 7), complete atrioventricular septal defect (n = 7), left persistent superior vena cava (n = 6) and viscerocardiac heterotaxy (n = 6). In this group there was one stillbirth, five infant deaths and four survivors. The overall survival rate and spectrum of other cardiac malformations were similar between the two groups. Prenatal diagnosis of other visceral features of cardiosplenic syndromes was inconsistent. CONCLUSION Cardiosplenic syndromes can be diagnosed with high accuracy by prenatal sonography. A diagnosis of left isomerism should be strongly suggested in the presence of a combination of at least two of the following: (1) complete atrioventricular septal defect or other structural heart disease; (2) interruption of inferior vena cava with azygos continuation; (3) early fetal heart block; (4) viscerocardiac heterotaxy. Right isomerism should be suspected in the presence of a combination of at least two of the following: (1) structural heart disease, namely complete atrioventricular septal defect; (2) juxtaposition of inferior vena cava and descending aorta; (3) viscerocardiac heterotaxy.

Abstract
BACKGROUND The Jing-Mai (variously translated as the Channel, Vessel or Meridians), as described by traditional Chinese medicine, probably exists and has represented the connections between various parts of human body during embryonic development. According to the Chinese theories, there are 14 major Jing-Mai within the human body, of which four are directly connected with the Heart. METHODS The described paths of the four Jing-Mai were compared with features of congenital syndromes involving particular types of congenital heart defects. RESULTS Specific correlation seem to exist between such four Jing-Mai and known developmental mechanisms underlying various congenital heart defects: the Kidney Jing-Mai-ectomesenchymal tissue migration abnormalities; the Spleen Jing-Mai-situs and looping defects; the Heart Jing-Mai-abnormal cell death; the Small Intestine Jing-Mai (and the Heart Jing-Mai)-extracellular matrix anomalies. CONCLUSIONS The Chinese theories seem to provide some intriguing insights into the pathogeneses of congenital heart defects. The Jing-Mai seems to distinguish from, but nevertheless have a close relationship with the blood vessels. Utilization of the Jing-Mai will probably enable a better understanding and development of new treatments for cardiovascular diseases.

Abstract
Post-mortem evaluation of a female sub-adult olive baboon (Papio cynocephalus anubis) revealed a case of ectopic spleen anomaly. Three spherical masses characterized the spleen anomaly. The splenic nodules were located on the left upper quadrant of the stomach, at the distal end of the pancreas. The anterior nodule measures 1.2 cm, the middle nodule 1.9 cm and the posterior nodule 1.3 cm in diameter. Normal spleen was not observed in this case. All the three ectopic splenic nodules showed normal histological architecture. A case of ectopic splenic nodules in baboon is important in that the spleen malformation can readily be mistaken for a pathological process.

Abstract
This report describes a 1-yr-old boy with biliary atresia (BA) and polysplenia syndrome (PS) who underwent successful living-related liver transplantation (LTx). At the time of initial hepatic portoenterostomy, he was noticed to have a preduodenal portal vein (PV), non-rotation of the intestine, and polysplenia. Because he did not achieve good bile excretion, he underwent a living-related LTx (using a left lateral segment from his mother) at the age of 14 months. Evaluation of the vascular anatomy was made by angiography, magnetic resonance imaging (MRI), computerized tomography (CT), and Doppler ultrasound. The PV was stenotic from the confluence of the superior mesenteric vein (SMV) and splenic vein (SpV) to the hepatic hilum. The retrohepatic inferior vena cava (IVC) was deficient cranially to the renal vein and was connected to the azygous vein. The supra-hepatic IVC was detected below the diaphragm and was connected to three hepatic veins. The common hepatic artery (HA) originated from the superior mesenteric artery. At LTx, the PV was dissected to the level of confluence of the SMV and the SpV, from which the venous graft was interposed using the donor's ovarian vein. Three hepatic veins were plastied into one orifice, which was anastomosed to the graft's hepatic vein under the diaphragm. The graft vascularity and function has been good for 1 yr after LTx. In the present case, sufficient pre-LTx evaluation of vascular anomalies seemed to help performance of the successful LTx.
