Abstract
Malrotation and midgut volvulus are surgical emergencies that commonly occur within the first month of life. The classic symptom is acute bilious vomiting, while nonspecific symptoms such as recurrent abdominal pain may be present in older children. Malrotation can be associated with duodenal obstruction caused by an abnormal peritoneal fibrous band or congenital anomalies, such as an annular pancreas or a preduodenal portal vein. Volvulus can lead to bowel ischemia and a life-threatening condition, thus prompt and accurate diagnosis is crucial. Diagnosis can be made through upper gastrointestinal series, ultrasonography, and CT, with ultrasonography being preferred as a screening tool due to its rapid and accurate diagnosis, without radiation exposure, in children. This pictorial essay discusses the key imaging findings and diagnostic approaches for malrotation and midgut volvulus, as well as diagnostic pitfalls based on actual cases.

Coexisting gastrointestinal and hepatobiliary tract anomalies in omphalocele and gastroschisis: A twenty-year experience in a single tertiary medical center. Pediatr Neonatol 2022; 63:468-473. [PMID: 35641386 DOI: 10.1016/j.pedneo.2022.03.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/30/2022] [Accepted: 03/10/2022] [Indexed: 10/18/2022] Open
Abstract
BACKGROUND Omphalocele and gastroschisis are the two most common congenital abdominal wall defects; however, no previous study has focused on gastrointestinal and hepatobiliary tract malformations in these two conditions. This study aimed to investigate the demographic characteristics, coexisting congenital gastrointestinal and hepatobiliary tract anomalies, hospital course, and outcomes of patients with gastroschisis and omphalocele. METHODS This is retrospective chart review of all patients admitted to one tertiary medical center in Taiwan between January 1, 2000 and June 30, 2020 with a diagnosis of gastroschisis or omphalocele. The medical records were reviewed to obtain demographic data regarding coexisting gastrointestinal and hepatobiliary tract anomalies and outcomes. RESULTS Of the 51 patients included, 21 had gastroschisis and 30 had omphalocele. Gastroschisis was associated with a significantly younger maternal age and a higher incidence of small for gestational age. Of the 30 patients with omphalocele, twelve had associated gastrointestinal and hepatobiliary anomalies. Seven of the 21 patients with gastroschisis had gastrointestinal anomalies, and none had hepatobiliary anomalies. Among the omphalocele patients, three (10%) had documented malrotation, and one developed midgut volvulus. Among gastroschisis patients, four patients (19%) had malrotation, and two developed midgut volvulus. There were no statistically significant differences in postoperative complications or mortality rates between those with and without gastrointestinal/hepatobiliary tract anomalies. CONCLUSION The diversity of coexisting gastrointestinal and hepatobiliary tract anomalies is higher in the omphalocele than in gastroschisis. In addition, we demonstrate that patients with gastroschisis or omphalocele have a higher rate of intestinal malrotation and midgut volvulus.

Abstract
Upper gastrointestinal series is considered the gold standard imaging test to evaluate for malrotation and midgut volvulus. US has been explored for this purpose in recent years and has been shown to be a good alternative because of its relatively good accuracy, fast learning curve for sonographers and radiologists, as well as convenience for children, clinical staff and radiologists in the neonatal intensive care unit. In this article we describe our experience and review the evidence supporting the use of emergency US primarily to diagnose midgut volvulus as well as its use as a problem-solving tool for the diagnosis of malrotation. The examination technique, normal and abnormal findings are described, with emphasis on the whirlpool and superior mesenteric artery cutoff signs to diagnose midgut volvulus.

Abstract
Background Malrotation with bowel ischemia is classically thought of as a disease of infants. However, the true prevalence of malrotation in both the pediatric and adult population is unknown due to the unclear number of asymptomatic patients. Case presentation A previously healthy 84-year-old man with no prior abdominal surgeries presented with an acute abdomen and was found on CT to have small bowel located in the right hemiabdomen and an abnormal SMA-SMV relationship suggestive of intestinal malrotation, as well as pneumatosis intestinalis. He underwent an exploratory laparotomy, where he was found to have a paraduodenal space which did not contain any bowel but was the likely source of an internal hernia. His duodenojejunal flexure was located to the right of the spinal column, the cecum in the left lower quadrant, a thick congenital band at the proximal jejunum, and multiple Ladd’s bands at the level of the duodenum. The bowel appeared viable and a Ladd’s procedure was performed. The patient had an uneventful post-operative course. Conclusions There is a lack of guidelines regarding screening for and management of asymptomatic malrotation in older children and adults. However, the traditional thinking is that asymptomatic malrotation diagnosed after two years of age poses minimal risk. This case illustrates the potential risk of an internal hernia in the setting of malrotation at any time during one’s lifetime.

Prenatal diagnosis of intestinal nonrotation using magnetic resonance imaging: Is it possible? Pediatr Radiol 2021; 51:1332-1338. [PMID: 33608743 DOI: 10.1007/s00247-021-04969-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 08/30/2020] [Accepted: 01/07/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Malrotation of the bowel refers to any variation in the rotation and fixation of the gastrointestinal tract during the first trimester and is most commonly detected postnatally. Nonrotation of the bowel and incomplete rotation of the bowel are subtypes of malrotation. OBJECTIVE To determine if the nonrotation subtype of malrotation of the bowel can be detected on prenatal magnetic resonance imaging (MRI). MATERIALS AND METHODS Cases from 2012 to 2018 with nonrotation of the bowel without obstruction confirmed by imaging, surgery and/or autopsy were compared to prenatal imaging. Prenatal imaging was retrospectively reviewed to determine if prenatal diagnosis of malrotation could be made. Exclusion criteria included diaphragmatic hernia, omphalocele and gastroschisis. RESULTS Ten cases of nonrotation diagnosed postnatally by upper gastrointestinal series (upper GI)/small bowel follow-through (SBFT) or autopsy had prenatal MRI. Prenatal MR studies were performed for assessment of heterotaxy syndrome with congenital heart disease (6/10), congenital heart disease with additional anomalies (suspected VACTERL [vertebral, anorectal, cardiac, tracheoesophageal, renal, limb] and suspected lung agenesis, ventriculomegaly) (3/10) and skeletal dysplasia (1/10). Eight upper GI/SBFT cases demonstrated nonrotation of the bowel without obstruction with the small bowel completely on one side of the abdomen contralateral to the stomach and the colon ipsilateral to the stomach; four cases were confirmed by surgery. The small bowel in one upper GI/SBFT case was unilateral contralateral to the stomach with a meandering colon. One case had nonrotation diagnosed at autopsy. There were no cases of postnatal midgut volvulus. Retrospective review of the 10 cases had prenatal MRI performed between 23 and 37 weeks of gestation. The coronal plane was the most optimal plane to assess the position of the stomach, small bowel and colon in relationship to each other. The small bowel was best assessed on T2-weighted images while the colon was best assessed on T1-weighted images. A nonrotated position of the small bowel was present in all 10 fetal MRI cases mirroring postnatal findings, with the small bowel contralateral to the stomach in 9/10 cases and ipsilateral to the stomach (in the right abdomen) in 1/10 cases. The colon was visualized by prenatal MRI in 9/10 cases, with 1 case limited due to a lack of T1-weighted imaging. A nonrotated position of the colon contralateral to the small bowel was present in 7/9 cases. In 2/9 cases, the colon was wandering, positioned on both sides of the midline. Colonic position in all nine cases matched postnatal findings. No cases presented with prenatal bowel obstruction. CONCLUSION Detection of nonrotation of the bowel is possible on prenatal MRI.

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
Intestinal malrotation is a continuum of congenital anomalies due to lack of rotation or incomplete rotation of the fetal intestine around the superior mesenteric artery axis. The abnormal bowel fixation (by mesenteric bands) or absence of fixation of portions of the bowel increases the risk of bowel obstruction, acute or chronic volvulus, and bowel necrosis. The clinical presentation of patients with malrotation without, with intermittent, or with chronic volvulus can be problematic, with an important minority presenting late or having atypical or chronic symptoms, such as intermittent vomiting, abdominal pain, duodenal obstruction, or failure to thrive. The diagnosis is heavily reliant on imaging. Upper GI series remain the gold standard with the normal position of the duodenojejunal junction lateral to the left-sided pedicles of the vertebral body, at the level of the duodenal bulb on frontal views and posterior (retroperitoneal) on lateral views. However, a variety of conditions might influence the position of the duodenojejunal junction, potentially leading to a misdiagnosis of malrotation. Such conditions include improper technique, gastric over distension, splenomegaly, renal or retroperitoneal tumors, liver transplant, small bowel obstruction, the presence of properly or malpositioned enteric tubes, and scoliosis. All of these may cause the duodenojejunal junction to be displaced. We present a series of cases highlighting conditions that mimic malrotation without volvulus to increase the practicing radiologist awareness and help minimize interpretation errors.

Malrotation is not associated with adverse outcomes after cardiac surgery in patients with heterotaxy syndrome. J Pediatr Surg 2018; 53:1494-1498.

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
BACKGROUND Infants with heterotaxy syndrome (HS) have abnormal lateralization of organs along the right-left body axis. Intestinal rotation abnormalities (IRAs) are a potential source of morbidity and mortality. For this study, our objective was to prospectively observe a cohort of infants with HS and determine the incidence and natural history of IRA. METHODS Infants ≤6 months of age with HS were enrolled in this prospective observational study. Exclusion criteria were other congenital abnormalities that necessitated abdominal surgery. HS was defined as any arrangement of organs that was not situs solitus or situs inversus along with associated congenital heart disease. The investigation for IRA was at the discretion of each participating center. RESULTS Infants were recruited from January 2012 to December 2016. Thirty-eight infants from 7 institutions were included; 22 infants had right isomerism and 16 infants had left isomerism. Twenty-nine infants (76%) were evaluated for IRAs; 21 of 29 evaluations (72%) were abnormal. Eight infants were investigated because of symptoms, and 21 infants were evaluated routinely. The median age at symptom presentation was 46 days (range: 5-171 days). Seven infants had a Ladd procedure; 4 were prophylactic, with 3 as part of a combined procedure, and 3 were emergent. No child suffered acute midgut volvulus over a median follow-up of 1.6 years (range: 0.06-4.93 years). CONCLUSIONS IRAs are common in infants with HS. Infants with symptoms presented by 6 months of age. There was no failure of expectant management resulting in midgut volvulus during a median follow-up of 1.6 years.

Abstract
Background To investigate the differences in cardiovascular disease, extracardiac anomalies and outcomes between fetuses with levocardia and dextrocardia. Methods Clinical demographics, prenatal features, postnatal characteristics and the outcomes of fetuses with levocardia or dextrocardia were recorded and analyzed. Results Sixty-five fetuses with dextrocardia and thirty-eight fetuses with levocardia were enrolled. Right ventricle outlet obstruction, atrioventricular septal defect and intestinal malrotation were common in both groups. Univentricular physiology, transposition of the great arteries and esophageal atresia were more frequent in fetuses with levocardia, whereas abnormal pulmonary venous connection, double outlet of right ventricle, left ventricle outlet obstruction and brain abnormalities were more frequent in the dextrocardia group. The accuracy of evaluating cardiac malformations was high, but the sensitivity in assessing extracardiac abnormalities was low. Conclusions Although the disorders have certain overlapping features, there are several differences between fetuses with levocardia and dextrocardia. These findings might improve patient counseling and perinatal management.

Abstract
BACKGROUND Anatomical imaging findings indicating normal bowel rotation can be identified on cross-sectional imaging, including magnetic resonance imaging (MRI) performed for non-related indications. OBJECTIVE The goal of our study was to assess whether non-targeted MRI can accurately assess intestinal malrotation. MATERIALS AND METHODS Four anatomical landmarks were assessed on MRIs of the chest, spine or abdomen performed from January 2006 to June 2014, on patients who also had upper gastrointestinal series (UGI) performed within 10 years of the MRI date: 1) retroperitoneal duodenum, 2) left upper quadrant duodenojejunal junction, 3) superior mesenteric artery to the left of the superior mesenteric vein, and 4) right lower quadrant cecum. Two attending radiologists, one pediatric and one abdominal radiologist, independently reviewed the MR images. The pediatric radiologist reviewed images from UGI (considered the gold standard) to determine the intestinal rotation for each case. Validation of the criteria was performed on new patients imaged through January 2016. RESULTS The original cohort included 109 MRIs (15 chest, 41 spine and 53 abdomen) done on 109 patients (42% males, mean age: 10.2 years). If each of the 4 anatomical questions were answered "yes" (4-YES), specificity was 100% for each radiologist and malrotation was appropriately excluded. Using the 4-YES criteria, the pediatric radiologist excluded malrotation in 71 patients (65%) and the abdominal radiologist excluded it in 65 (60%), with concurrence for 57 patients. Validation of the 4-YES criteria in 23 new patients appropriately proved the 4-YES rule, with neither labeling the one new malrotation case 4-YES. CONCLUSION If a radiologist can confidently answer "yes" to the four questions evaluated in this study, then intestinal rotation can be safely considered normal. Normal bowel rotation should be commented upon in MRI reports when these four anatomical locations are imaged, thus helping patients avoid unnecessary UGI and radiation exposure.

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.

Characteristics of Hospitalizations for the Glenn Procedure in Those With Isomerism Compared to Those Without. Pediatr Cardiol 2016; 37:1409-1415.

Abstract
Isomerism, also known as heterotaxy, is a unique clinical entity in which there are mirror imaged findings in the thoracic. In the abdomen, the arrangement of organs can be random. The anatomic findings also have functional consequences. Isomerism has been known to increase morbidity and mortality in those with functionally univentricular hearts. The aim of this study was to determine the impact of isomerism on the Glenn hospitalization. Data from the 1997 to 2012 Kids' Inpatient Database were utilized for this cross-sectional study. Admissions during which a Glenn procedure was done were identified. Next, these admissions were separated into those with and without isomerism. Admission characteristics were then compared in a univariate fashion as well as by regression analysis. Length of hospitalization, cost of hospitalization, extracorporeal membrane oxygenation, and inpatient mortality were the outcomes of interest. A total of 4959 admissions with a Glenn procedure were identified. Of these, 450 were associated with isomerism. The median age at which the Glenn procedure was done was 10 and 13 months in those without and with isomerism, respectively. Neither univariate nor regression analysis demonstrated any significant difference in length of hospitalization, cost of hospitalization, need for extracorporeal membrane oxygenation, and inpatient mortality between those with and without isomerism. Isomerism does not impact the characteristics of the Glenn hospitalization. Those with isomerism did tend to be older when they underwent the Glenn procedure.

Prophylactic versus symptomatic Ladd procedures for pediatric malrotation. J Surg Res 2016; 205:327-330.

Abstract
BACKGROUND Intestinal malrotation can lead to volvulus resulting in necrosis, sepsis, and death. For symptomatic patients, treatment includes the Ladd procedure. However, debate remains regarding the timing and need for intervention for asymptomatic infants. We evaluated our experience with Ladd procedures including a clinical practice of prophylactic surgery for asymptomatic patients. MATERIALS AND METHODS A retrospective review of pediatric patients undergoing the Ladd procedure was performed. Prophylactic Ladd procedures were identified as those occurring before any malrotation-related symptoms. Results were analyzed with student t test, Mann-Whitney U, and chi-squared tests. RESULTS From 2011-2014, 42 patients (prophylactic = 19, symptomatic = 23) underwent the Ladd procedure. The median age (IQR, interquartile range) of patients was 9.6 (3.9-18) mo and 18 (2.4-52) mo for prophylactic and symptomatic patients, respectively (P = 0.38). In patients who underwent symptomatic Ladd procedures, nine (39%) had volvulus and one (4.3%) had bowel necrosis at time of surgery. No prophylactic Ladd procedure patients required reoperation, whereas six (26%) symptomatic patients required malrotation-related reoperations (P = 0.02). Median (IQR) days to full enteral feeds were 5.0 d (3.3-6.8) versus 7.4 (5.0-11; P = 0.11), whereas median days to discharge were 8.0 d (6.1-11) versus 11 d (7.5-32) until discharge (P = 0.09) for prophylactic and symptomatic patients, respectively. CONCLUSIONS Although symptomatic patients represent sicker children, the postoperative complications appear to be higher. For infants with known malrotation, prophylactic operations may be beneficial and should be considered. A larger, prospective study to demonstrate effectiveness and generalizability for prophylactic Ladd procedure is warranted.

Abstract
PURPOSE To assess the usefulness of the relative position of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in diagnosing intestinal malrotation in situs anomaly. MATERIALS AND METHODS From January 2004 to April 2015, 33 patients with situs anomalies were enrolled in this study who underwent abdominal USG, CT or MRI as well as upper gastrointestinal series (UGIS) or surgery: situs inversus (n=16), left isomerism (n=10), and right isomerism (n=7); age 21.2±23.2years (mean±standard deviation), range 0-72 years. The intestinal malrotation was confirmed with UGIS and/or operation in 16 patients. Relative positions of the SMV to the SMA were classified into four groups by reviewing abdominal USG, CT, or MRI: right sided, left sided, ventral sided, and dorsal sided. The incidence of malrotation was analyzed for each group. RESULTS In 16 patients with situs inversus, there was reversed SMA-SMV relationship: left sided (n=11) or ventral sided (n=5). One situs inversus patient with ventral sided SMV had intestinal malrotation (6.25%). 17 patients with situs ambiguus showed various SMA-SMV relationships (ventral sided, n=7; left sided, n=5; right sided, n=4; dorsal sided, n=1). Among them, 15 patients (88.2%) had intestinal malrotation. Two patients with normal rotation had either right sided or dorsal sided SMV. CONCLUSION Situs ambiguus was commonly associated with intestinal malrotation with a variable SMA-SMV relationship. Reversal of the mesenteric vascular relationship was observed in situs inversus with normal rotation, not excluding the possibility of intestinal malrotation.

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
OBJECTIVE To assess the incidence and impact of extracardiac anomalies on the prognosis of fetuses with heterotaxy syndrome. METHODS All fetuses diagnosed with heterotaxy syndrome by three experienced examiners over a period of 14 years (1999-2013) were reviewed retrospectively. RESULTS In total, 165 fetuses with heterotaxy syndrome were diagnosed in the study period. One hundred and fifty (90.9%) had cardiac defects; extracardiac anomalies that did not involve the spleen were present in 26/165 (15.8%) cases. Of the total study cohort, termination of pregnancy was performed in 49 (29.7%) cases, intrauterine death occurred in 11 (6.7%), postnatal death occurred in 38 (23.0%) and 67 (40.6%) were alive at the latest follow-up, resulting in a total perinatal and pediatric mortality of 59.4%. Among the 105 liveborn neonates, 15 (14.3%) had extracardiac anomalies with significant impact on the postnatal course: one neonate died following repair of an encephalocele, six had successful treatment for various types of intestinal malrotation and/or atresia and one underwent hiatal hernia repair; the remaining seven had biliary atresia, of which five died and the two survivors are awaiting liver transplantation. The status of the spleen was assessed in 93/105 liveborn children and was found to be abnormal in 84/93 (90.3%). There were three cases of lethal sepsis, all associated with asplenia. Of the 38 postnatal deaths, 29 (76.3%) had a cardiac cause, seven (18.4%) had an extracardiac cause and in two (5.2%) the reason was uncertain. CONCLUSIONS Although the leading causes of death in fetuses and children with heterotaxy syndrome are cardiac, a small subset of fetuses have extracardiac anomalies with significant impact on outcome. These anomalies often escape prenatal detection, and therefore neonates at risk should be monitored for bowel obstruction, biliary atresia and immune dysfunction in order to allow timely intervention through a multidisciplinary approach.

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 The management of intestinal rotational abnormalities (IRA) in heterotaxy syndrome (HS) remains inconsistent. Because of the high incidence of malrotation in HS, screening of asymptomatic patients is standard of care in some institutions. The Ladd procedure is the treatment for malrotation, and has been reported to have high complication rates in HS patients. METHODS We performed a systematic review of publications describing IRA in pediatric HS patients from January 1993 to present. The incidence of volvulus on surgical exploration was determined. Perioperative and long-term outcomes were analyzed to determine complication and mortality rates. RESULTS Eleven retrospective studies describing 649 HS patients were identified. Of all patients with HS, 27% (176/649) underwent Ladd procedure. Only 1.2% (8/649) of HS patients included had volvulus. Postoperative complications occurred in 25 patients (14%), including a 10% incidence of small bowel obstruction. Perioperative and overall mortality rates after Ladd procedure were 3% and 21%, respectively. Six studies described mesenteric width, reporting 43% to have narrow mesentery. CONCLUSION The Ladd procedure is not without significant morbidity and mortality in heterotaxy patients. Further prospective studies should investigate predictors of mesenteric width to spare the unnecessary morbidity of surgery in patients who are at low risk for volvulus.

Abstract
OBJECTIVE Patients with malrotation, or an intestinal rotation abnormality (IRA), can experience serious adverse events. Increasingly, asymptomatic patients are being diagnosed with malrotation incidentally. Patients with symptomatic malrotation require surgery in an urgent or semiurgent manner to address their symptoms. The treatment of asymptomatic or incidentally discovered malrotation remains controversial. METHODS Data were compiled from a broad search of Medline, Cochrane, Embase and Web of Science from January 1980 through January 2013 for five questions regarding asymptomatic malrotation. RESULTS There is minimal evidence to support screening asymptomatic patients. Consideration may be given to operate on asymptomatic patients who are younger in age, while observation may be appropriate in the older patient. If reliably diagnosed, atypical malrotation with a broad-based mesentery and malposition of the duodenum can be observed. Regarding diagnostic imaging, the standard of care for diagnosis remains the upper gastrointestinal contrast study (UGI), ultrasound may be useful for screening. A laparoscopic approach is safe for diagnosis and treatment of rotational abnormalities. Laparoscopy can aid in determining whether a patient has true malrotation with a narrow mesenteric stalk, has nonrotation and minimal risk for volvulus, or has atypical anatomy with malposition of the duodenum. It is reasonable to delay Ladd procedures until after palliation on patients with severe congenital heart disease. Observation can be considered with extensive education for family and caregivers and close clinical follow-up. CONCLUSIONS There is a lack of quality data to guide the management of patients with asymptomatic malrotation. Multicenter and prospective data should be collected to better assess the risk profile for this complex group of patients. A multidisciplinary approach involving surgery, cardiology, critical care and the patient's caregivers can help guide a watchful waiting management plan in individual cases.

The risk of volvulus in abdominal wall defects. J Pediatr Surg 2015; 50:570-2. [PMID: 25840065 DOI: 10.1016/j.jpedsurg.2014.12.017] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2014] [Revised: 12/22/2014] [Accepted: 12/22/2014] [Indexed: 11/21/2022]
Abstract
BACKGROUND Congenital abdominal wall defects are associated with abnormal intestinal rotation and fixation. A Ladd's procedure is not routinely performed in these patients; it is believed intestinal fixation is provided by adhesions that develop post-repair of the defects. However, patients with omphalocele may not have adequately protective postoperative adhesions because of difference in the inflammatory state of the bowel wall and in repair strategy. The aim of this study is to describe the occurrence of midgut volvulus in patients with gastroschisis or omphalocele. METHODS A retrospective chart review was performed for all patients managed in a single institution born between 1/1/2000 and 12/31/2008 with a diagnosis of gastroschisis or omphalocele. Patient charts were reviewed through 12/31/2012 for occurrence of midgut volvulus or need for second laparotomy. RESULTS Of the 206 patients identified with abdominal wall defects, 142 patients (69%) had gastroschisis and 64 patients (31%) had omphalocele. Patients' follow up ranged from 4 years to 13 years. The median gestational age was 36 weeks (26-41 weeks) and the median birth weight was 2.42 kg (0.8-4.87 kg). None of the patients with gastroschisis developed midgut volvulus, however two patients (3%) with omphalocele developed midgut volvulus. CONCLUSIONS No patients with gastroschisis developed midgut volvulus. Therefore, the current practice of not routinely performing a Ladd's procedure is a safe approach during surgical repair of gastroschisis. The two cases of volvulus in patients with omphalocele may be related to less bowel fixation. It is necessary to examine current practice in regards to the need for assessing the risk of volvulus during omphalocele closure and counseling of these patients. This assessment may be achieved via routine examination of the width of the small bowel mesenteric base, whenever feasible; however, the sample size is relatively small to draw any definitive conclusions.
