The Blunt Liver and Spleen Trauma (BLAST) audit: national survey and prospective audit of children with blunt liver and spleen trauma in major trauma centres. Eur J Trauma Emerg Surg 2023; 49:2249-2256. [PMID: 35727342 PMCID: PMC10520113 DOI: 10.1007/s00068-022-01990-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 04/24/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE To compare the reported and observed management of UK children with blunt liver or spleen injury (BLSI) to the American Pediatric Surgical Association (APSA) 2019 BLSI guidance. METHODS UK Paediatric Major Trauma Centres (pMTCs) undertook 1 year of prospective data collection on children admitted to or discussed with those centres with BLSI and an online questionnaire was distributed to all consultants who care for children with BLSI in those centres. RESULTS All 21/21 (100%) pMTCs participated; 131 patients were included and 100/152 (65%) consultants responded to the survey. ICU care was reported and observed to be primarily determined using haemodynamic status or concomitant injuries rather than injury grade, in accordance with APSA guidance. Bed rest was reported to be determined by grade of injury by 63% of survey respondents and observed in a similar proportion of patients. Contrary to APSA guidance, follow-up radiological assessment of the injured spleen or liver was undertaken in 44% of patients before discharge and 32% after discharge, the majority of whom were asymptomatic. CONCLUSIONS UK management of BLSI differs from many aspects of APSA guidance. A shift towards using clinical features to determine ICU admission and readiness for discharge is demonstrated, in line with a strong evidence base. However, routine bed rest and re-imaging after BLSI is common, contrary to APSA guidance. This disparity may exist due to concern that evidence around the incidence, presentation and natural history of complications after conservatively managed BLSI, particularly bleeding from pseudoaneurysms, is weak.

Abstract
BACKGROUND The coronavirus (COVID-19) pandemic affected the presentation of many conditions. This study analyses and describes the impact of the COVID-19 pandemic on the management of appendicitis in children and the role of laparoscopy. MATERIALS AND METHODS We performed a prospective (during the pandemic) and retrospective (historic control) review of the management of appendicitis in a tertiary paediatric surgical unit. Preoperative data, operative findings and patient outcomes were compared between groups to identify differences between the study periods and to identify any factors predictive of outcomes. RESULTS Sixty-two patients were identified in the pre-pandemic cohort, 72 in the pandemic cohort. There was no significant difference in patient demographics, length of admission or time between admission and surgery between groups. There was however a significantly longer time to presentation to hospital in the pandemic group. Clinical outcomes were comparable between the two groups, with no difference in the presence of surgical complications or histologically advanced appendicitis between the two groups. Laparoscopic surgery was safely used to manage appendicitis in the pandemic cohort through utilisation of a COVID-19 pathway that included guidance on testing, and use of personal protective equipment (PPE). Conservative management in the pandemic cohort was reserved for patients with appendicitis with the presence of mass formation. CONCLUSION Despite a delayed presentation to hospital, there was no rise in the incidence of complicated appendicitis, complications of surgery or length of stay during the COVID-19 pandemic. Laparoscopic appendicectomy was also shown to be a safe and effective standard for the management of appendicitis during the pandemic. LEVEL OF EVIDENCE III, treatment.

Delayed versus early repair of inguinal hernia in preterm infants: A systematic review and meta-analysis. J Pediatr Surg 2022; 57:527-533. [PMID: 35934526 DOI: 10.1016/j.jpedsurg.2022.07.001] [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: 10/07/2021] [Revised: 05/28/2022] [Accepted: 07/04/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To evaluate the clinical outcomes of herniotomy in preterm infants undergoing early versus delayed repair, the risk factors for complications, and to identify best timing of surgery. METHODS Medline, Embase and Central databases were searched from inception until 25 Jan 2021 to identify publications comparing the timing of neonatal inguinal hernia repair between early intervention (before discharge from first hospitalization) and delayed (after first hospitalisation discharge) intervention. Inclusion criteria was preterm infants diagnosed with inguinal hernia during neonatal intensive care unit admission. Results were analyzed using fixed and random effects meta-analysis (RevManv5.4). RESULTS Out of 721 articles found, six studies were included in the meta-analysis. Patients in the early group had lower odds of developing incarceration [odds ratio (OR) 0.43, 95% confidence interval (CI) 0.34-0.55, I2 = 0%, p < 0.001]; but higher risk of post-operative respiratory complications (OR 4.36, 95% CI 2.13-8.94, I2 = 40%, p < 0.001). No significant differences were reported in recurrence rate (OR 3.10, 95% CI 0.90-10.64, I2 = 0%, p = 0.07) and surgical complication rate (OR 0.94, 95% CI 0.18-4.83, I2 = 0%, p = 0.94) between early and delayed groups. CONCLUSION While early inguinal hernia repair in preterm infants reduces the risk of incarceration, it increases the risk of post-operative respiratory complications compared to delayed repair. Surgeons should discuss the risks and benefits of delaying inguinal hernia repair with the caregivers to make an informed decision best suited to the patient physiology and circumstances.

NIRS as a biomarker of bowel ischaemia & surgical pathology: A meta-analysis of studies in newborns. Early Hum Dev 2021; 161:105437.

Abstract
OBJECTIVE We performed a meta-analysis on Near-infrared Spectroscopy (NIRS) as a biomarker of bowel ischaemia. SUMMARY BACKGROUND DATA NIRS allows non-invasive assessment of gastrointestinal regional oxygen saturation (GrSO2). Studies to date have focused on the feasibility of NIRS in clinical practice and its reproducibility. GrSO2 can be used alone, or in conjunction with cerebral NIRS to give a Cerebral Splanchnic Oxygenation Ratio (CSOR). We assess published data on abdominal NIRS as a marker of bowel ischaemia. METHODS A literature review was conducted using the PRISMA method. Data on GrSO2 and CSOR in controls and patients with confirmed ischaemia was included in a meta-analysis, and used to identify a diagnostic threshold. RESULTS 14 studies were identified. Meta-analysis demonstrated that GrSO2 (p < 0.01) and CSOR (p < 0.01) were significantly lower in neonates with bowel pathology associated with ischaemia than controls. Area under the curve for GrSO2 was 0.80, with Youden's index highest (0.52) at a GrSO2 of 42% (specificity 91% and sensitivity 62%). For CSOR, area under the curve is 0.89, with Youden's index highest (0.69) at 0.76 (specificity of 80%, sensitivity 90%). CONCLUSIONS Splanchnic NIRS correlates with bowel ischaemia. Low GrSO2 is consistently associated with ischaemia, although a specific cut off level in each patient is hard to define. However, values below 42% correlate strongly with ischaemia while values above 52% are more suggestive of patients without bowel pathology. CSOR of below 0.76 is strongly suggestive of ischaemia. Trends within individuals are likely to be able to provide even more clinically correlatable and diagnostic data.

Abstract
Background This study analyses the impact of anaesthetic blockade and intraperitoneal local anaesthetic infiltration on paediatric laparoscopic inguinal hernia repair. Method A retrospective review of paediatric laparoscopic hernia repairs versus open repairs. Anaesthetic blockade, analgesic consumption and postoperative pain scores were compared between groups. Results 155 children underwent laparoscopic repair, 150 underwent open repairs. Median age was 7.2 months (16 days–14 years) in the laparoscopic group, 6 months (17 days–13 years) in the open group. Anaesthetic blockade varied significantly; 62.7% of open cases had caudal blockade compared to 21.6% laparoscopic (p < 0.001). A subset of laparoscopic patients had peritoneal local anaesthetic infiltration. 10.1% of laparoscopic cases required recovery analgesia, compared to 1.3% of open cases (p = 0.001). Postoperative analgesic consumption was significantly higher in the laparoscopic group. Peritoneal infiltration reduced analgesic consumption in the laparoscopic group (p = 0.038). Age < 2 was associated with use of caudal (p < 0.001), which reduced analgesic consumption. Conclusions Laparoscopy was associated with increased use of recovery analgesia. Caudal reduced the need for rescue and postoperative analgesia. Intraperitoneal infiltration of local anaesthetic is associated with reduced postoperative analgesia in laparoscopy. In suitable patients undergoing laparoscopic surgery, combination caudal and peritoneal infiltration may prove a useful adjunctive analgesic strategy.

Abstract
BACKGROUND Management of gastroschisis involves either primary or staged closure. Bowel ischemia and abdominal compartment syndrome (ACS) are possible complications that can be related to a method of treatment. NIRS monitoring has never been applied in this group of patients and may allow for earlier detection of complications. OBJECTIVE To assess near-infrared spectroscopy (NIRS) monitoring in neonates with gastroschisis for detecting changes in tissue oxygenation (rSO2) related to bowel reductions or height of bowel in the silo and for detecting tissue ischemia. METHODS Patients with gastroschisis and controls underwent continuous multi-channel assessment of oxygenation of the brain (CrSO2), kidney (RrSO2) and bowel (GrSO2) in a prospective pilot study. RESULTS Fifteen neonates were treated with primary closure (n = 3) or staged closure (n = 12); two had confirmed bowel ischemia, none developed ACS.There was no significant correlation between height of the bowel and GrSO2 at apex (p = .72) or base (p = .54) within the silo. During staged reductions there was a clinically non-significant change in RrSO2 (Δ-2.5%, p = .04), but no significant changes in CrSO2 (p = .11), and GrSO2 of apex (p = .97) and base (p = .31). Patients with confirmed ischemia had GrSO2 that were lower than controls. CONCLUSIONS Measuring GrSO2 through a silo is feasible. Staged reduction seems safe based on NIRS measurements, with minimal effect of hydrostatic pressure on bowel oxygenation. NIRS was able to detect subtle changes in intra-abdominal renal perfusion during reduction and could differentiate healthy and ischemic bowel.

Antenatally detected abdominal cyst: Does cyst size and nature determine postnatal symptoms and outcome? Early Hum Dev 2020; 147:105102.

Abstract
BACKGROUND The outcome of antenatally detected fetal intra-abdominal cysts is highly variable and challenging to predict. Antenatal ultrasound scans may be of value in predicting postnatal outcome. AIMS To report antenatal and postnatal course of fetal intra-abdominal cysts identified on antenatal ultrasound and establish the value of cyst dimensions for predicting outcome. STUDY DESIGN Retrospective observational study. SUBJECTS All intra-abdominal cysts diagnosed in a single centre between 2013 and 2019. OUTCOME MEASURES Cyst characteristics were recorded from radiological reports and postnatal diagnosis and outcomes documented. Growth characteristics were identified to distinguish different diagnosis. The maximum antenatal diameter of all cysts was identified and the best cut-off diameter to predict whether a cyst would persist postnatally or require surgery was identified. Best cut-off values were identified using Youden index. RESULTS Of the 38 cysts identified on antenatal ultrasound, 24 (63%) persisted postnatally, 8 required surgery (21%) and 4 (11%) were not considered an intra-abdominal cyst postnatally. Ovarian cyst and duplication cyst may have different growth characteristics. In the prediction of cysts persisting postnatally, the area under the ROC curve (AUC) was 0.81 (95% CI, 0.66-0.95). Two cut off values were identified, 37.5 mm (50% sensitivity, specificity 100%, Youden's index 0.50) and 28.5 mm (sensitivity 65%, specificity 85%, Youden's index 0.50). In the prediction of surgery, no optimal diameter was found; AUC was 0.57 (95% CI, 0.34-0.81). CONCLUSIONS Maximum antenatal cyst diameter is useful for the prediction of whether a cyst will persist postnatally but not for the prediction of surgery.

Role of ECMO in congenital diaphragmatic hernia. Arch Dis Child Fetal Neonatal Ed 2018; 103:F178-F181.

Abstract
Congenital diaphragmatic hernia (CDH) is typified morphologically by failure of diaphragmatic development with accompanying lung hypoplasia and persistent pulmonary hypertension of the newborn (PPHN). Patients who have labile physiology and low preductal saturations despite optimal ventilatory and inotropic support may be considered for extracorporeal membrane oxygenation (ECMO). Systematic reviews into the benefits of ECMO in CDH concluded that any benefit is unclear. Few randomised trials exist to demonstrate clear benefit and guide management. However, ECMO may have its uses in those that have reversibility of their respiratory disease. A few centres and networks have demonstrated an increase in survival rate by post hoc analysis (based on a difference in referral patterns with the availability of ECMO) in their series. One issue may be that of careful patient selection with regard to reversibility of pathophysiology. At present, there is no single test or prognostication that predicts reversibility of PPHN and criteria for referral for ECMO is undergoing continued refinement. Overall survival is similar between cannulation modes. There is no consensus on the time limit for ECMO runs. The optimal timing of surgery for patients on ECMO is difficult to definitively establish, but it seems that repair at an early stage (with careful perioperative management) is becoming less of a taboo, and may improve outcome and help with either coming off ECMO or decisions on withdrawal later. The provision of ECMO will continue to be evaluated, and prospective randomised trial are needed to help answer question of patient selection and management.

Abstract
Congenital diaphragmatic hernia (CDH) in the newborn poses challenges to the multi-disciplinary teams involved in its management. Mortality remains significantly high, despite growing understanding and treatment options. Early intubation of antenatally diagnosed cases is crucial in preventing deterioration and persistent pulmonary hypertension. Early recognition of cases not diagnosed on antenatal scan, with appreciation of differential diagnosis, requires an index of suspicion and imaging. Increasing options and modalities are available, with only modest, if any, survival advantage. Permissive hypercapnea and minimal ventilation have made the most significant impact on survival in modern era. High-frequency oscillatory ventilation (HFOV), inhaled nitric oxide (iNO), treatment of pulmonary hypertension, and ECMO are used in a somewhat stepwise manner for stabilisation. Delayed surgery has become established later in management plan. The impact of individual therapies (e.g. HFOV, iNO, ECMO) on outcome is difficult to ascertain. Little level 1 or 2 evidence exists. Randomised studies and reviews on the role of ECMO have not yet proven any long-term survival benefit. One pilot randomised study of thoracoscopic repair suggests increased acidosis; intraoperative blood gases and CO2 levels should be closely monitored. Monitoring tissue oxygenation should be considered. There is no evidence to suggest the best patch material.

Abstract
A neonate with gastroschisis had silo placement and near-infrared spectroscopy (NIRS) monitoring of intestinal haemoglobin oxygen saturation (RSO2). An ischemic loop of bowel demonstrated decreased RSO2, with reversal of clinical ischemia and RSO2 postoperatively. This demonstrates possible advantage of monitoring intestinal RSO2 in neonates at risk of ischemia, and response to intervention.

Abstract
OBJECTIVE To evaluate the 4-year results following a randomised controlled trial (RCT) comparing open (ONF) and laparoscopic (LNF) Nissen fundoplication in children. BACKGROUND It is assumed that long-term results of ONF and LNF are comparable. No randomised studies have been performed in children. METHODS A follow-up study was performed in children randomised to ONF or LNF (clinicaltrials.gov identifier NCT00259961). Recurrent gastro-oesophageal reflux (GER) was documented by upper gastrointestinal contrast study and/or 24-h pH study. Nutritional status, retching and other symptoms were investigated. A questionnaire was used to assess the quality of life before and after surgery. RESULTS Thirty-nine children were randomised to ONF (n=20) or LNF (n=19). There were 15 ONF and 16 LNF neurologically impaired children. One patient (ONF group) was lost to follow-up. Follow-up was 4.1 years (3.1-5.3) for ONF group and 4.1 years (2.6-5.1) for LNF group (p=0.9). Seven neurologically impaired children had died by the time of follow-up (3 ONF, 4 LNF). Incidence of recurrent GER was 12.5% in the ONF and 20% in the LNF (p=ns). One patient in each group underwent redo-Nissen fundoplication. Nutritional status improved in both groups, as indicated by a significant increase in weight Z-score (p<0.01). Gas bloat and dumping syndrome were present in both groups (p=ns). Incidence of retching was lower in the laparoscopic group (p=0.01). Quality of life improved in both groups (p=ns). CONCLUSIONS Open and laparoscopic Nissen provide similar control of reflux and quality of life at follow-up. LNF is associated with reduced incidence of retching persisting at 4-year follow-up. TRIAL REGISTRATION NUMBER NCT00259961.

Abstract
An 18-month-old boy was witnessed swallowing a cluster of five magnetic toy balls. He was coincidentally noted on plain x-rays to have also recently swallowed a watch battery and a small screw. Initial outpatient management with serial review and x-rays was unsuccessful, and delayed inpatient surgical care by 9 days. Although the child never manifested features of systemic or gastrointestinal upset, emergency laparotomy confirmed a resultant jejunocolic fistula. This case demonstrates how clinical assessment of children who have swallowed magnets separately from each other can be falsely reassuring, and highlights the potential dangers of outpatient management. We recommend children who have swallowed separately >1 magnetic objects (or >1 objects capable of magnetic attraction) be managed as inpatients with active observation and timely foreign body removal.

Abstract
Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has been described by a number of authors and is increasingly widely practiced. We present a technical learning point. CDH is associated with the presence of a hernia sac in around 20% of all cases. In this case the presence of a ruptured hernia sac complicated the thoracoscopic repair of a left sided CDH, as it was initially difficult to recognise. Once the anatomy was clarified the repair was satisfactorily completed and the child made a rapid postoperative recovery. This technical note is to warn other surgeons that a tunnel like appearance of the diaphragmatic defect may in fact be due to the presence of a torn hernia sac, which requires excision before closure of the defect.

Abstract
BACKGROUND Mammary duct ectasia is uncommon in children, and is usually considered to be an acquired disease in adults. However the occurrence in infants and children suggest it may be developmental. AIMS To report a case series of mammary duct ectasia, and review the published literature to ascertain the common findings and histological findings in children. STUDY DESIGN Case series report and review of the literature. RESULTS We report three cases of mammary duct ectasia, an unusual disease in children. The most common presenting features are a bloody nipple discharge; there may also be a palpable mass or general breast enlargement. Two patients in this series presented with large masses simulating other conditions. Summary of all reported cases in children found that symptoms can arise from infancy, but is most common around the age of 3 years (range 2 months to 13 years), with a 5:2 male:female ratio. Histology centres on peri-ductal inflammation and dilation. Haemosiderin laden macrophages were seen commonly in this series; and may represent a histological marker in children. The disease is often self-limiting. Patients may require surgery for persistent nipple discharge or lump. CONCLUSIONS Duct ectasia should be entertained in small infants and children presenting with both small and large peri-areolar breast masses and/or bleeding. The occurrence of the disease in infants suggests that mammary duct ectasia may represent a developmental anomaly in the paediatric population.

Abstract
Vascular tumours (haemangiomas and malformations) are common tumours of infancy and childhood. They represent a group of mostly benign conditions, which present early, can grow rapidly and be symptomatic or disfiguring. There are various management options, with different cosmetic and functional outcomes. Haemangiomas and vascular malformations have different clinical courses which dictate respective management; differentiating them is key. Haemangiomas are generally self-limiting after initial proliferation; generally management is conservative. Symptoms can call for treatment. Options include laser, steroids, chemotherapy and surgery. Propanolol, the newest modality of treatment, may have a dramatic effect in problematic lesions. Vascular malformations are a less common group of heterogenous lesions, with some overlap between entities. They do not involute. Treatment options include laser therapy, sclerotherapy, embolisation, and surgery. Emerging therapies include photodynamic therapy and angiogenesis inhibitors. This review will outline the evidence for the various modalities in managing these conditions.

Abstract
INTRODUCTION Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has been described, but its efficacy and safety have not been validated. The aim was to compare our experience of thoracoscopy with laparotomy repair. METHODS After ethics approval, we reviewed the notes of neonates with CDH operated in our institution between 2003 and 2008. Two historical groups were compared: infants who underwent laparotomy (2003-2008) or thoracoscopy (2007-2008). Data were compared by t test or Mann-Whitney tests. RESULTS Thirty-five children had open repair of CDH, and 13 had thoracoscopic repair. Groups were homogeneous for age and weight. Five (38%) neonates who had thoracoscopy were converted to open for surgical difficulties (n = 4) and O(2) desaturation (n = 1). Patch repair was used in 12 (34%) open and 6 (46%) thoracoscopic repairs. End-tidal CO(2) was significantly elevated during thoracoscopy, but this was not reflected in arterial CO(2) or pH. There were 3 (8%) recurrences after open repair and 2 (25%) after thoracoscopy (P = .19). CONCLUSION Thoracoscopic repair of CDH is feasible. Arterial blood gases should be closely monitored. Despite higher EtCO(2), conversion to open was mainly because of difficult repair. A randomized trial is necessary to assess the effect of thoracoscopy on ventilation and recurrences.

Abstract
Considerable advances have been achieved in paediatric surgery during the last two decades, which can be partly ascribed to a better understanding of the physiological response to operations and the use of that knowledge to decrease the metabolic response where appropriate. Alongside this, minimally invasive surgery is now well established for many surgical conditions in the neonate, infant and child. The metabolic response to surgery differs in neonates to that seen in adults: there is a small increase in oxygen consumption and resting energy expenditure immediately after surgery with a return to normal levels by 12-24 h. The increase in resting energy expenditure is significantly greater in infants undergoing a major operation than in those subjected to a minor procedure. The limited increase in energy expenditure may be due to diversion of energy from growth to tissue repair. There are limited data available on older children, but they appear to have a different pattern of postoperative resting energy expenditure. There is a fall in the early postoperative period, similar to data collected in adults, but no late hypermetabolism. Protein metabolism mirrors energy expenditure and contributes to the overall changes observed. Various factors affect the magnitude of the response. It seems that in children intraoperative thermoregulation and metabolism are significant drivers of many of the postoperative changes. Minimally invasive surgery may maintain preoperative metabolic processes by altering the postoperative processes on a physiological level or by maintaining thermoregulation in children. The mechanism and potential benefit of these observations need further investigation.

Abstract
The aim of this paper is to review the factors which may affect breath (13)CO(2)/(12)CO(2) natural abundance in patients undergoing surgery or intensive care. Intravenous glucose administration is a major determinant of the (13)CO(2)/(12)CO(2) of breath as intravenous glucose preparations are almost all derived from cornstarch. In addition, the oxidation of endogenous substrates can affect the (13)CO(2)/(12)CO(2) ratio. During many endoscopic procedures, such as laparoscopic surgery, carbon dioxide insufflation is used to provide a working space. As medical CO(2) is relatively depleted in (13)CO(2) compared with endogenous and exogenous metabolic CO(2) sources, breath (13)CO(2)/(12)CO(2) measurements can be used to estimate CO(2) absorption during these procedures. However, all these factors may also be affected by the bicarbonate pool, making a definitive attribution of changes in breath (13)CO(2)/(12)CO(2) to a single factor problematic.

Abstract
Monocyte class II major histocompatibility complex (MHC) expression is necessary for antigen presentation and stimulation of T-cells. The aim of this study was to correlate monocyte class II MHC response to operative stress in children and the possible influence of cytokines in the postoperative period. We studied 21 children undergoing elective abdominal surgery. Operative stress score (OSS) was calculated. Monocyte class II MHC expression was measured preoperatively, immediately after surgery, 24 and 48 h postoperatively, using flow cytometry. Class II MHC is expressed as mean fluorescence intensity (MFI) of monocytes expressing MHC (mean +/- SD). Cytokine levels (interleukins 1ra, 6, and 10, and tumor necrosis factor-alpha) were also measured. Data between time points were compared using repeated measures ANOVA. There was an immediate postoperative decrease in class II MHC expression, with lowest levels 24 h postoperatively (preoperative 50 +/- 23.6, 24 h 18.2 +/- 9.4, P < 0.0001 vs. preoperative). At 48 h there was partial recovery in class II MHC, but levels were still significantly lower than preoperative (23.9 +/- 11.1, P < 0.001). The degree of monocyte depression was related to the magnitude of operative stress. Patients who had OSS <10 displayed some recovery in expression at 48 h 25.5 +/- 11.1), whereas in patients with OSS > or = 10 (severe surgical stress), expression further decreased at 48 h (MFI 14.0 +/- 0.1). There was an elevation of interleukin-1ra in the immediate postoperative period in both groups. There was no elevation in the other cytokines. Abdominal surgery in children decreases monocyte MHC expression. Class II MHC depression was related to magnitude of surgical trauma, implying that more severe immuneparesis follows surgery of greater magnitude. This may predispose to postoperative infection.

Abstract
UNLABELLED We performed a randomized controlled trial to compare the inflammatory and immune responses to Nissen fundoplication in infants and children undergoing either open or laparoscopic surgery. METHODS Forty children undergoing Nissen fundoplication were randomized to laparoscopy or open surgery using minimization with respect to age, neurologic status, and operating surgeon. Intraoperative and postoperative analgesias were standardized. Inflammatory markers (plasma malondialdehyde, nitrate plus nitrite level, and cytokines) and monocyte class II major histocompatibility complex expression were measured preoperatively, at end of surgery, 4, 24, and 48 hours postoperatively. Postoperative changes were compared between open and laparoscopic groups. RESULTS There were no significant changes in circulating malondialdehyde, nitrates plus/ nitrite, interleukin-10, or tumor necrosis factor alpha in the postoperative period in either group. Interleukin-1 receptor antagonist (IL-1rA) and IL-6 were significantly increased in both groups, with a tendency for greater elevation of IL-1rA in the open group. Monocyte major histocompatibility complex expression fell significantly in both groups; however, this fall appeared to be slightly more marked in the open group. CONCLUSIONS The postoperative cytokine response is similar in children undergoing open and laparoscopic Nissen fundoplication. This trial indicates that laparoscopy may partly reduce postoperative immune suppression.

Abstract
BACKGROUND/PURPOSE The aim of this study was to review the management of the gastrointestinal tract in cloacal exstrophy and to assess the effect of spinal dysraphism on nutritional outcome. METHODS Twenty-two patients with cloacal exstrophy were reviewed retrospectively. Gastrointestinal and spinal anomalies were documented. The need for nutritional supplementation was recorded. Weights at 1 and 5 years of age were used to assess growth in childhood. RESULTS Ten patients were treated initially with ileostomy, 7 with colostomy, and 3 without stoma. Two patients died before surgical reconstruction. Total parenteral nutrition (TPN) was utilized in 8 infants for a median of 10 days (range, 5 to 200). Three patients had complications with colostomies requiring conversion to ileostomy. Patients with an ileostomy required more nutritional supplementation compared with patients with a colostomy (50% v 28%). High-output stoma losses were more common in patients with an ileostomy (40% v 14%). Fourteen patients (67%) with spinal dysraphism had a higher incidence of failure to thrive in the first year of life (69% v 26%) and multiple episodes of enteritis (40% v 25%). Two neonates with duodenal atresia and small bowel deletion died within the first month of life. One patient with short bowel syndrome died of TPN-associated liver disease at 6 months of age. There were no other deaths. CONCLUSIONS The gastrointestinal tract contributes significantly to the morbidity and mortality in cloacal exstrophy. Nutritional supplementation is more frequently required in patients with an ileostomy. Stoma complications were higher in those with a colostomy. Morbidity is high in patients with spinal dysraphism.

Abstract
OBJECTIVES To assess the accuracy of ultrasound diagnosis of duplex kidneys in the fetus and to identify prognostic features of antenatal sonography associated with this diagnosis. METHODS Retrospective identification of cases with an antenatal diagnosis of duplex kidney was made from computerized databases. Results of postnatal radiological investigations were obtained from the unit where delivery took place. RESULTS A total of 75% of cases seen in a multidisciplinary fetal renal clinic were correctly diagnosed as having a duplex kidney. Prognostic sonographic features are described. Detection of two separate poles or a ureterocele were strongly associated with a correct diagnosis. Accuracy was increased when two or more prognostic features were seen. CONCLUSION Accurate sonographic diagnosis of duplex kidneys in the fetus is possible in a dedicated multidisciplinary setting. Antenatal counseling and planning of postnatal care for the infant can be made with a high degree of certainty.

Abstract
UNLABELLED The absorption of carbon dioxide (CO2) used for positive pressure pneumoperitoneum may lead to an increased CO2 load. CO2 elimination during laparoscopy has not been investigated previously in paediatrics. The aim of this study was to characterise the pattern of CO2 elimination during laparoscopic surgery in infants and children. METHODS Twenty children undergoing laparoscopy and 19 children undergoing laparotomy for elective abdominal operations were studied. Pneumoperitoneum was achieved using insufflation of unheated CO2. CO2 elimination (metabolically produced + absorbed; milliliters per kilogram per minute) was measured minute by minute during the operation by indirect calorimetry. End-tidal CO2 (kPa) was recorded every 10 minutes. The above variables were assessed before CO2 insufflation, during pneumoperitoneum, and after desufflation. RESULTS Before insufflation, CO2 elimination was 4.6 +/- 0.3 ml/kg/min and increased after 15 minutes of pneumoperitoneum to 5.2 +/- 0.3 (P <.001). Post desufflation, CO2 elimination decreased toward preinsufflation values, but did not return to baseline by the end of operation (5.8 +/- 0.3; P <.001). End-tidal CO2 was 4.7 +/- 0.2 preinsufflation, peaked at 1 hour (5.3 +/- 0.2; P <.001) and subsequently decreased in response to ventilatory adjustments. The total amount of CO2 insufflated was positively correlated with patient age (r2 = 0.27; P <.01). CO2 elimination was age related, as indicated by multilevel model analysis and by negative correlations between maximum increase in CO2 elimination and both age (r2 = 0.27; P <.01) and weight (r2 = 0.29; P <.01). These data suggest that the younger or smaller the child, the larger the increase in CO2 elimination. Seven patients (35%) responded to desufflation with a sharp transient increase in CO2 elimination, which did not appear to be related to patient age, length of pneumoperitoneum, abdominal pressure, or type of operation. CONCLUSIONS During pneumoperitoneum, younger children absorb proportionately more CO2 than older individuals. The short-lived increase in CO2 elimination postdesufflation may be related to an increase in venous return from the lower limbs after release of the abdominal pressure. These findings suggest that small children warrant close monitoring during laparoscopy and during the immediate postoperative period.
