Abstract
INTRODUCTION Exomphalos is an anterior abdominal wall defect resulting in herniation of contents into the umbilical cord. Severe associated chromosomal anomalies and congenital heart disease (CHD) are known to influence mortality, but it is not clear which cardiac anomalies have the greatest impact on survival. METHODS We performed a retrospective review of the treatment and outcome of patients with exomphalos over a 30-year period (1990-2020), with a focus on those with the combination of exomphalos major and major CHD (EMCHD). RESULTS There were 123 patients with exomphalos identified, 59 (48%) had exomphalos major (ExoMaj) (defect > 5 cm or containing liver), and 64 (52%) exomphalos minor (ExoMin). In the ExoMaj group; 17% had major CHD (10/59), M:F 28:31, 29% premature (< 37 weeks, 17/59) and 14% had low birth-weight (< 2.5 kg, 8/59). In the ExoMin group; 9% had major CHD (6/64), M:F 42:22, 18% premature and 10% had low birth-weight. The 5-year survival was 20% in the EMCHD group versus 90% in the ExoMaj with minor or no CHD [p < 0.0001]. Deaths in the EMCHD had mainly right heart anomalies and all of them required mechanical ventilation (MV) for pulmonary hypoplasia prior to cardiac intervention. In contrast, survivors did not require mechanical ventilation prior to cardiac intervention. CONCLUSION EMCHD is associated with high mortality. The most significant finding was high mortality in those with right heart anomalies in combination with pulmonary hypoplasia, especially if pre-intervention mechanical ventilation is required.

Abstract
INTRODUCTION Laparoscopic pyloromyotomy is now an accepted procedure for the treatment of pyloric stenosis. However, it is clear that during the implementation period there are significantly higher incidences of mucosal perforation and incomplete pyloromyotomy. We describe how we introduced a new laparoscopic procedure without the complications associated with the learning curve. MATERIALS AND METHODS Five consultants tasked one surgeon to pilot and establish laparoscopic pyloromyotomy before mentoring the others until they were performing the procedure independently; all agreed to use exactly the same instruments and operative technique. This involved a 5mm 30-degree infra-umbilical telescope with two 3mm instruments. Data were collected prospectively. RESULTS Between 1 January 2013 and 31 December 2017, 140 laparoscopic pyloromyotomies were performed (median age 27 days, range 13-133 days, male to female ratio 121:19). Fifty-five per cent of procedures were performed by trainees. Complications were one mucosal perforation and one inadequate pyloromyotomy. There were no injuries to other organs, problems with wound dehiscence or other significant complications. The median time of discharge was one day (range one to six days). CONCLUSION Our rate of perforation and incomplete pyloromyotomy was 1.4%, which is equivalent to the best published series of either open or laparoscopic pyloromyotomy. We believe that this resulted from the coordinated implementation of the procedure using a single technique to reduce clinical variability, increase mentoring and improve training. This approach appears self-evident but is rarely described in the literature of learning curves. In this age of increased accountability, new technologies should be incorporated into routine practice without an increase in morbidity to patients.

Abstract
BACKGROUND Congenital mesoblastic nephroma is a rare disease. Treatment is surgical in the first instance. Chemotherapy has traditionally been thought not to have a role. Recent literature suggests a 50% mortality rate for recurrent/metastatic disease. MATERIALS AND METHODS This study is a retrospective case review of prospectively collected data. Demographics, histopathology, treatment, outcomes and follow up were reviewed. RESULTS Nine patients, 6 male and 3 female, were included. The median age at presentation was one month (range 0-7 months); follow-up was for a median of 21.5 months (range 16-79 months). Two patients had mixed and classical subtypes and the other five had the cellular subtype. Surgery was completed by an open procedure in eight patients and laparoscopically in one. There were three recurrences; two were local and one was pulmonary. Recurrences were treated with a combination of chemotherapy, radiotherapy and surgery. One patient with recurrent disease died from acute-on-chronic respiratory failure secondary to lung irradiation but was disease free. The other eight are disease free, alive and well with no sequelae at latest follow-up. CONCLUSIONS Surgery remains the mainstay of management with chemo- and radiotherapy reserved for unresectable tumours or adjuvant management of recurrent disease. Specimen-positive margins are not an indication for instituting chemotherapy. The tyrosine kinase pathway seems to be a potential target for future chemotherapeutic agents although it is too early to assess how that will impact on the management of congenital mesoblastic nephroma.

Abstract
INTRODUCTION The concentration of major trauma experience at Camp Bastion has allowed continuous improvements to occur in the patient pathway from the point of wounding to surgical treatment. These changes have involved clinical management as well as alterations to the physical layout of the hospital, training and decision making. Consideration of the human factors has been a major part of these improvements. METHODS We describe the Camp Bastion patient pathway with the communication template that focused decision making at various key moments during damage control resuscitation and damage control surgery (DCR-DCS). This system identifies four key stages: 'command huddle', 'snap brief', 'sit-reps' (situation reports) and 'sign-out/debrief'. The attitude of staff to communication and decision making is also evaluated. RESULTS Twenty cases admitted to Camp Bastion with battlefield injuries were studied from 6 September to 6 October 2012. Qualitative responses from 115 members of staff were collected. All patients were haemodynamically shocked with a median pH of 7.25 (range: 6.83-7.40) and a median of 18 units of mixed red cells and plasma were transfused. In 89% of instances, theatre staff were aware of what was required of them at the beginning of the case, 86% felt there were regular updates and 93% understood what was required of them as the case progressed. CONCLUSIONS The evolution of the hospital at Camp Bastion has been a unique learning experience in the field of major trauma. The Defence Medical Services have responded with continuous innovation to optimise DCR-DCS for seriously injured patients. Together with the improvements in clinical care, a communication and decision making matrix was developed. Staff evaluation showed a high degree of satisfaction with the quality of communication.

Abstract
BACKGROUND Traumatic paediatric handlebar injury (HBI) is known to occur with different vehicles, affect different body regions, and have substantial associated morbidity. However, previous handlebar injury research has focused on the specific combination of abdominal injury and bicycle riding. Our aim was to fully describe the epidemiology and resultant spectrum of injuries caused by a HBI. METHODS Retrospective data analysis of all paediatric patients (<18 years) in a prospectively identified trauma registry over a 10-year period. Primary outcome was the HBI, its location and management. The effects of patient age, vehicle type, the impact region, and Injury Severity Score (ISS) were also evaluated. HBI patients were compared against a cohort injured while riding similar vehicles, but not having sustained a HBI. RESULTS 1990 patients were admitted with a handlebar-equipped vehicle trauma; 236 (11.9%) having sustained a HBI. HBI patients were twice as likely to be aged between 6 and 14 years old compared with non-HBI patients (OR 2.2; 95% CI 1.5-3.2). 88.6% of the HBI patients sustained an isolated injury, and 45.3% had non-abdominal handlebar impact. There were no significant differences in median ISS (p=0.4) or need for operative intervention (OR 1.1; 95% CI 0.9-1.5) between HBI and non-HBI patients. HBI patients had a significantly longer LOS (1.8 days vs. 1.2 days; p=0.001), and more frequently required a major operation (OR 3.4; 95% CI 2.2-5.4). The majority of splenic, renal and hepatic injuries were managed conservatively. CONCLUSIONS Although the majority of paediatric HBI is associated with both intra-abdominal injury and bicycle riding, it produces a spectrum of potentially serious injuries and patients are more likely to undergo major surgery. Therefore these patients should always be treated with a high degree of suspicion.

Abstract
BACKGROUND The deployed Intensive Therapy Unit (ITU) in the British military field hospital in Camp Bastion, Afghanistan, admits both adults and children. The purpose of this paper is to review the paediatric workload in the deployed ITU and to describe how the unit copes with the challenge of looking after critically injured and ill children. METHODS Retrospective review of patients <16 years of age admitted to the ITU in the British military field hospital in Camp Bastion, Afghanistan, over a 1-year period from April 2011 to April 2012. RESULTS 112/811 (14%) admissions to the ITU were paediatric (median age 8 years, IQR 6-12, range 1-16). 80/112 were trauma admissions, 13 were burns, four were non-trauma admissions and 15 were readmissions. Mechanism of injury in trauma was blunt in 12, blast (improvised explosive device) in 45, blast (indirect fire) in seven and gunshot wound in 16. Median length of stay was 0.92 days (IQR 0.45-2.65). 82/112 admissions (73%) were mechanically ventilated, 16/112 (14%) required inotropic support. 12/112 (11%) died before unit discharge. Trauma scoring was available in 65 of the 80 trauma admissions. Eight had Injury Severity Score or New Injury Severity Score >60, none of whom survived. However, of the 16 patients with predicted mortality >50% by Trauma Injury Severity Score, seven survived. Seven cases required specialist advice and were discussed with the Birmingham Children's Hospital paediatric intensive care retrieval service. The mechanisms by which the Defence Medical Services support children admitted to the deployed adult ITU are described, including staff training in clinical, ethical and child protection issues, equipment, guidelines and clinical governance and rapid access to specialist advice in the UK. CONCLUSIONS With appropriate support, it is possible to provide intensive care to children in a deployed military ITU.

Abstract
Haemorrhage from severe pelvic fractures can be associated with significant mortality. Modern civilian trauma centres may manage these injuries with a combination of external pelvic fixation, extra-peritoneal packing and/or selective angiography; however, military patterns of wounding are different and deployed medical facilities may be resource constrained. We report two successful instances of pelvic packing using chitosan impregnated gauze (Celox) when conventional surgical attempts at vascular control had failed. We conclude that pelvic packing should be considered early in patients with military pelvic trauma and major haemorrhage, as part of damage control surgery and that Celox gauze may be a useful adjunct. In our cases, the Celox gauze was easily removed after 24-48 hours without significant bowel adhesions and did not leave a residual phelgmon (of exudate or gel) that may predispose to infection.

Abstract
Damage Control Resuscitation and Damage Control Surgery (DCR-DCS) is an approach to managing severely injured patients according to their physiological needs, in order to optimise outcome. Key to delivering DCR-DCS is effective communication between members of the clinical team and in particular between the surgeon and anaesthetist, in order to sequence and prioritise interventions. Although the requirement for effective communication is self-evident, the principles to achieving this can be forgotten and sub-optimal when unexpected problems arise at critical points during management of challenging cases. A system is described which builds on the 'World Health Organisation (WHO) safer surgery checklist' and formalises certain stages of communication in order to assure the effective passage of key points. We have identified 3 distinct phases: (i) The Command Huddle, once the patient has been assessed in the Emergency room; (ii) The Snap Brief, once the patient has arrived in the Operating Room but before the start of surgery; and (iii) The Sit-Reps, every 10 minutes for the entire theatre team to maintain situational awareness and allow effective anticipation and planning.

Abstract
INTRODUCTION International humanitarian law requires emergency medical support for both military personnel and civilians, including children. Here we present a detailed review of paediatric admissions with the pattern of injury and the resources they consume. METHODS All paediatric admissions to the hospital at Camp Bastion between 1 January and 29 April 2011 were analysed prospectively. Data collected included time and date of admission, patient age and weight, mechanism of injury, extent of wounding, treatment, length of hospital stay and discharge destination. RESULTS Eighty-five children (65 boys and 17 girls, median age: 8 years, median weight: 20 kg) were admitted. In 63% of cases the indication for admission was battle related trauma and in 31% non-battle trauma. Of the blast injuries, 51% were due to improvised explosive devices. Non-battle emergencies were mainly due to domestic burns (46%) and road traffic accidents (29%). The most affected anatomical area was the extremities (44% of injuries). Over 30% of patients had critical injuries. Operative intervention was required in 74% of cases. The median time to theatre for all patients was 52 minutes; 3 patients with critical injuries went straight to theatre in a median of 7 minutes. A blood transfusion was required in 27 patients; 6 patients needed a massive transfusion. Computed tomography was performed on 62% of all trauma admissions and 40% of patients went to the intensive care unit. The mean length of stay was 2 days (range: 1-26 days) and there were 7 deaths. CONCLUSIONS Paediatric admissions make up a small but significant part of admissions to the hospital at Camp Bastion. The proportion of serious injuries is very high in comparison with admissions to a UK paediatric emergency department. The concentration of major injuries means that lessons learnt in terms of teamwork, the speed of transfer to theatre and massive transfusion protocols could be applied to UK paediatric practice.

Abstract
BACKGROUND/PURPOSE Insertion of permanent central venous access (Broviac line) can be a challenge in neonates especially when sites for peripherally inserted central catheters (PICC) have been exhausted. The landmark technique (LT) has been well described for the percutaneous insertion of central lines in neonates but can be associated with significant complications including death. The use of the ultrasound-guided approach for temporary central line access has been reported but as yet there are no reports of the adaptation of the technique for Broviac line insertion in neonates. METHOD A prospective database records all procedures carried out by the vascular access team and any complications which occur; this database was reviewed from November 2004 to January 2008. RESULTS A consecutive series of 34 neonates underwent insertion of 36 Broviac lines using the ultrasound-guided percutaneous technique with a 2.7 Fr silastic line and a 3 Fr peel-apart sheath. Median gestational age was 34 weeks (range 24-40), chronological age was 102 days (14-209 days), weight 2.9 kg (0.63-4.1). Successful cannulation occurred in 100% of patients. There were no cases of arterial puncture or perioperative complications due to surgery. CONCLUSION The ultrasound-guided percutaneous approach for insertion of tunnelled permanent vascular access is safe in neonates with no surgical complications in our series. However, it is a technically demanding procedure to do in neonates and should not be attempted without significant prior experience.

Abstract
INTRODUCTION The usual indications for oesophageal replacement in childhood are intractable corrosive strictures and long-gap oesophageal atresia. Generally, paediatric surgeons attempt to preserve the native oesophagus with repeat dilatations. However, when this is not successful, an appropriate conduit must be fashioned to replace the oesophagus. The neo-oesophagus should allow normal oral feeding, not have gastro-oesophageal reflux, and be able to function well for the life-time of the patient. PATIENTS AND METHODS A Medline search for oesophageal replacement, oesophageal atresia, gastric transposition, colon transposition, gastric tube, caustic stricture was conducted. The commonest conduits including whole stomach, gastric tube, colon and jejunum are all discussed. RESULTS No randomised controlled studies exist comparing the different types of conduits available for children. The techniques used tend to be based on personal preference and local experience rather than on any discernible objective data. The biggest series with long-term outcome are reported for gastric transposition and colon replacement. Comparison of a number of studies shows no significant difference in early or late complications. Early operative complications include graft necrosis, anastomotic leaks and sepsis. Late problems include strictures, poor feeding, gastro-oesophageal reflux, tortuosity of the graft and the development of Barrett's oesophagus. The biggest series, however, seem to have lower complications than small series probably reflecting the experience, built up over years, in their respective centres. CONCLUSIONS Long-term follow-up is recommended because of the risks of late strictures, excessive tortuosity of the neo-oesophagus and the development of Barrett's oesophagus.

Abstract
We report a case of megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS), occurring in association with mydriasis, in a female infant born to consanguineous Asian parents. This association has not previously been reported and is of interest because mydriasis has been found in a murine MMIHS model produced by knockout of the genes coding for the alpha3 subunit or the beta2 and beta4 subunits of the neuronal nicotinic acetylcholine receptor. This may provide an important clue to the genetic basis of MMIHS in humans.

Abstract
BACKGROUND AND AIMS Mucin genes are expressed in a site specific manner throughout the gastrointestinal tract. Little is known about the expression pattern in the oesophagus. In this study we have investigated MUC gene expression in both the normal oesophagus and specialised intestinal metaplasia (Barrett's oesophagus). PATIENTS Archived paraffin embedded material from eight specimens of normal oesophagus, 18 Barrett's oesophagus, eight gastric metaplasia, six high grade dysplasia, and six cases of adenocarcinoma were examined for expression of the mucin genes MUC1-6. METHODS Mucin mRNA was detected by in situ hybridisation using [(35)S] dATP labelled oligonucleotide probes. Mucin core protein was detected by immunohistochemistry. RESULTS Normal oesophagus expressed MUC5B in the submucosal glands and MUC1 and MUC4 in the stratified squamous epithelium. Barrett's oesophagus strongly expressed MUC5AC and MUC3 in the superficial columnar epithelium, MUC2 in the goblet cells, and MUC6 in the glands. In high grade dysplasia and adenocarcinoma there was downregulation of MUC2, MUC3, MUC5AC, and MUC6, but upregulation of MUC1 and MUC4 in half of the specimens examined. CONCLUSIONS Normal oesophagus and Barrett's oesophagus have a novel pattern of mucin gene expression. Barrett's oesophagus expressed the mucins associated with normal gastric epithelium and normal intestinal epithelium. While most mucin genes were downregulated in severely dysplastic and neoplastic tissues, there was upregulation of the membrane bound mucins MUC1 and MUC4. This may prove useful in detecting early signs of progression to adenocarcinoma of the oesophagus.

Abstract
BACKGROUND Bone marrow transplantation (BMT) patients frequently develop life-threatening problems that have similar clinical presentations but differing aetiologies. Despite intensive investigation by haematological, biochemical, and microbiological means, accurate diagnosis is not always possible. Histological and microbiological examination of biopsies from the affected organ may be indicated to enable an accurate diagnosis to be made in these patients. Here we assess the indications, findings, and outcomes in patients who have required surgical biopsy after BMT. PROCEDURE We retrospectively reviewed all BMT patients who had surgical biopsies between February 1994 and January 1997. Twenty-six patients (1-46 years, median age 10 years) underwent 40 biopsies from the upper and lower GI tract, lung, or liver. Indications for BMT were: relapsed leukaemia = 18; other types of leukaemia = 3; aplastic anaemia=3; other diseases = 2. Type of BMT: matched related donor = 3, unrelated T-cell depleted donor = 23. RESULTS Eleven (42%) cases had a change in management; 4 (16%) patients avoided further aggressive therapy because of poor prognosis. Unexpected diagnoses were found in 7 biopsies: 1 acute colitis, 1 duodenal ulcer, 1 liver aspergilloma, 2 transfusion siderosis, 1 radiation fibrosis of the lung, and 1 cytomegalovirus infection of the lung. Three patients were noted to have complications after their procedure. CONCLUSIONS Surgical biopsies for undiagnosed problems can be of benefit in the management of very sick patients who have received bone marrow transplantations. Despite the fact that these patients are so unwell, there is a low rate of complications related to surgery and anaesthesia.

Abstract
BACKGROUND AND STUDY AIMS One reason why many surgeons do not attempt laparoscopic cholangiography is that it is considered to be technically difficult and to produce poor-quality images. PATIENTS AND METHODS A retrospective comparison was made of twenty randomly selected intraoperative cholangiograms taken during laparoscopic cholecystectomy for each year from 1991 to 1994 (n = 80) by assigning a score (0-4) on the basis of anatomical parameters and radiographic quality. Twenty randomly selected intraoperative cholangiograms taken during open cholecystectomy (OC) were used as controls. RESULTS The average score for the laparoscopic cholangiograms (LCs) was significantly lower than the average for OC cholangiograms (2.3 vs. 3.4, P< 0.001). In addition, a learning curve was demonstrated, which showed significant improvement in the quality of LCs over the years. Analysis showed that in LCs, only 34 % succeeded in demonstrating the entire biliary tree and only 49% managed to show the extrahepatic duct system. Choledocholithiasis could only be ruled out in 53 % of LC films, compared with 80 % of controls. CONCLUSIONS Despite an improvement in the quality of laparoscopic cholangiography, it remains inferior to cholangiography during open cholecystectomy. Recommendations are made regarding ways in which improvements could be achieved.

Abstract
We have tried to review the evidence for the organisation of paediatric surgical care. Difficulties arise because of the lack of published data from district general hospitals concerning paediatric surgical conditions. Hence much of the debate about the surgical management of children is based on anecdotal evidence. However, at a time when the provision of health care is being radically reorganised to an internal market based on a system of purchasers and providers it is more important than ever to understand the issues at stake. Two separate issues have been discussed: the role of the specialist paediatric centre and the provision of non-specialist paediatric surgery in district general hospitals. There are arguments for and against large regional specialist paediatric centres. The benefits of centralisation include concentration of expertise, more appropriate consultant on call commitment, development of support services, and junior doctor training. The disadvantages include children and their families having to travel long distances for care, and the loss of expertise at a local level. If specialist paediatric emergency transport is available the benefits of centralisation far outweigh the adverse effects of having to take children to a regional paediatric intensive care centre. Specialist paediatric centres are aware of the importance of treating children and their parents as a family unit as highlighted by the Platt committee; this is an important challenge and enormous improvements have occurred to provide proper accommodation for families while their children are treated in hospital. To keep these arguments of large distances and separation from the home in context, one paediatric intensive care unit in Victoria, Australia, providing a centralised service to a region larger in are than England and with a similar admission rate, has a lower mortality rate than the decentralised paediatric intensive care provided in the Trent region of the UK. There is clear evidence that all neonatal surgery and anaesthesia should be conducted only by specialists. The debate now centres around the number of complex surgical cases a unit should treat to maintain its specialist status. The NHS executive, in its guidelines on contracting for specialist services, emphasises that "Sensible contracting needs to take into account the optimum population size not only for the stability of contracted referrals but also to give sufficient 'critical mass' for clinical effectiveness." Achieving this balance has consequences, not just for the maintenance of surgical expertise, but for the essential ancilliary services. There is clear evidence in anaesthesia that anaesthetists doing small numbers of neonatal procedures had significantly worse results. The same seems to be true in the fields of oncology, radiology, pathology, and intensive care. The reasons why the results of management of certain paediatric conditions are better at specialist centres are open to speculation. Presumably greater exposure to rare complex cases, concentration of expertise, more peer review, and a trickle down effect of the multidisciplinary approach all help to keep health care workers up to date with current world practice. In addition, it allows for appropriate specialist on call rotas and dedicated junior staff. If insufficient numbers of specialist surgical cases are being treated at a centre then the whole multidisciplinary team suffers. The 1989 NCEPOD report states "that paediatricians and general surgeons must recognise that small babies differ from other patients not only in size, and that they pose quite separate problems of pathology and management." The need for large centres of paediatric surgical expertise is now accepted by the Royal College of Surgeons of England, the British Association of Paediatric Surgeons, the Senate of Surgery of Great Britain and Ireland, the Royal College of Paediatrics and Child Health, the Royal College of Anaesthetists, the Audit

Abstract
We report a case of coeliac axis thrombosis and splenic infarction presenting in a girl of 14 years who had been on the oral contraceptive pill (OCP), Marvelon (ethinyloestradiol 30 microg plus desogestrel 150 microg, Organon, Cambridge, UK), for 3 weeks. She had no other risk factors for thrombo-embolism. Diagnosis was made with duplex Doppler ultrasound and confirmed with dynamically-enhanced comput-ed tomography and magnetic resonance angiography, thus avoiding the need for percutaneous arteriography. Though mesenteric thrombo-embolic disease is recognised in association with use of the combined OCP, it has not previously been reported to affect the coeliac axis. Paediatricians and surgeons should be aware of the risks to young girls on the OCP, and consider it in their differential diagnosis of the acute abdomen.
