Abstract
Liver and small bowel transplant is an established treatment for infants with IFALD. Despite organ reduction techniques, mortality on the waiting list remains high due to shortage of size-matched pediatric donors. Small abdominal cavity volume due to previous intestinal resection poses a significant challenge to achieve abdominal closure post-transplant. Seven children underwent tissue expansion of abdominal skin prior to multiorgan transplant. In total, 17 tissue expanders were placed subcutaneously in seven children. All seven subjects underwent re-exploration to deal with complications: hematoma, extrusion, infection, or port related. Three expanders had to be removed. Four children went on to have successful combined liver and small bowel transplant. Two children died on the waiting list of causes not related to the expander and one child died from sepsis attributed to an infected expander. Tissue expansion can generate skin to facilitate closure of abdomen post-transplant, thus allowing infants with small abdominal volumes to be considered for transplant surgery. Tissue expansion in children with end-stage liver disease and portal hypertension is associated with a very high complication rate and needs to be closely monitored during the expansion process.

Abstract
BACKGROUND AND AIM A select group of children with short bowel syndrome (SBS) and intestinal failure-associated liver disease (IFALD) fulfill the criteria for isolated liver transplantation (iLTx). Long-term results in this group of patients have not been reported. METHODS A retrospective study of the medical records of 8 survivors of 14 children who underwent iLTx for SBS and IFALD from 1998 to 2005, managed by a multidisciplinary intestinal rehabilitation team at our institution. RESULTS Median follow-up is 107.5 months (range 89-153 months). Five of 8 children were weaned from parenteral nutrition (PN) to enteral nutrition (EN) in a median of 10 months after iLTx (range 3-32 months). Three of 5 children were subsequently weaned from EN to full oral feeding in 13, 24, and 53 months after stopping PN, whereas the remaining 2 are still receiving EN 118 and 74 months after stopping PN. These 5 children maintain their weight median z scores with a median increase of 1.59 (range 1.24-1.79) compared with the pretransplant z score, whereas the height z scores show fluctuations through the years with a median change of 0.12 (range -0.29 to 0.36). The other 3 of 8 children developed progressive intestinal failure; 2 underwent isolated small bowel transplantation 112 and 84 months after iLTx and the third is receiving PN. CONCLUSIONS Children with SBS and IFALD who have the potential for adaptation in the residual bowel can undergo iLTx, but it is a treatment option to be exercised with extreme caution. These children need close follow-up with an experienced multidisciplinary team to monitor nutritional outcomes and may need consideration for transplant or nontransplant surgery in the long term.

Abstract
Following paediatric SBMT, size discrepancy between the recipient's abdomen and the graft may lead to ACS, graft dysfunction, and death. We report our experience with SAC in these patients. Between 04/1993 and 03/2009, 57 children underwent 62 SBMTs. When abdominal wall tension seemed excessive for safe PAC, SAC was performed, using a Silastic® sheet and a vacuum occlusive dressing. Transplantations with SAC (23 combined liver and small bowel [CLB]) were compared with those with PAC [14 ISB and 25 CLB]. Indications for transplantation, preoperative status (after stratification for ISB/CLB transplants), age at transplantation, donor-to-recipient weight ratio, reduction in bowel and/or liver, and incidence of wound complications were not different in both groups. Post-operative intubation, stay in intensive care unit, and hospital stay were prolonged after SAC. Two deaths were related to ACS after PAC, none after SAC. Since 2000, one-yr patient survival is 73% after ISB transplantation and 57% vs. 75% after CLB transplantation with PAC vs. SAC, respectively (NS). SAC safely reduces severe ACS after paediatric SBMT and can be combined with graft reduction for transplantation of small recipients.

Abstract
INTRODUCTION Local haemostatic agents are used for the control of surgical haemorrhage when standard techniques are inadequate, but there are few studies of these products in children. PATIENTS AND METHODS This was a prospective, open-label study in which children (aged 4 weeks to 6 years) undergoing liver resection with or without segmental liver transplantation were treated with TachoSil, a collagen patch coated with a dry layer of human fibrinogen and human thrombin, if minor (i. e., oozing) or moderate bleeding was present after primary haemostatic treatment. Time to haemostasis after TachoSil application was the primary endpoint. Safety was assessed by adverse events (AEs), including post-operative infections, symptoms of graft rejection and re-operations. RESULTS Enrolment was stopped early after 16 children had entered the study. 13 children underwent whole liver resection and transplantation and 3 patients underwent segmental resection. Satisfactory haemostasis was achieved in 13 children (81.3%; 95% CI: 61.8-100%) at 3 min and in 1 child at 8 min. Occurrence of AEs was as expected, with most being known complications of the underlying disease, surgical procedure, or use of immunosuppressive medication. No AEs were considered to be related to the use of TachoSil. CONCLUSIONS The use of TachoSil for haemostasis after primary haemostatic treatment appears to be safe and effective in children undergoing liver resection.

Abstract
A male infant was diagnosed with atypical hemolytic uremic syndrome (aHUS) at the age of 5.5 months. Sequencing of the gene (CFH) encoding complement factor H revealed a heterozygous mutation (c.3644G>A, p.Arg1215Gln). Despite maintenance plasmapheresis he developed recurrent episodes of aHUS and vascular access complications while maintaining stable renal function. At the age of 5 years he received an isolated split liver graft following a previously established protocol using pretransplant plasma exchange (PE) and intratransplant plasma infusion. Graft function, renal function and disease remission are preserved 2 years after transplantation. Preemptive liver transplantation prior to the development of end stage renal disease is a valuable option in the management of aHUS associated with CFH mutations.

Abstract
Selected livers from controlled NHBD are accepted for OLT in adults. Recent evidence has shown good medium-term outcome. The purpose of this study was to report our experience of pediatric OLT with whole and partial grafts from NHBD, analyzing complications and outcome. Retrospective review of all the recipients who underwent primary OLT between December 2005 and December 2008, using livers from NHBD. Four children (one male child) mean age was 9.5 yr (0.2-17), mean weight was 26 kg (range 2.6-48), underwent OLT using NHBD. Mean donor age was 14.2 yr, and mean WIT (systolic BP<50 mmHg to cold perfusion) 12.2 min (range 10-15). Two children received reduced grafts and two full grafts. Mean cold ischemia time was 7.18 h (range 6-8). Liver function tests one wk and nine months post-OLT confirmed a good graft function. One child was treated for two episodes of acute rejection. Post-transplant complications included two cases of mild ischemic cholangiopathy treated conservatively. Graft and patient survival was 100% with a mean follow-up of 19 months (range 8.1-43.4). Short- to medium-term follow-up suggests that liver grafts from young NHBD with short warm and cold ischemia times can be safely utilized in pediatric transplantation.

Abstract
This preliminary study reports the results obtained from a patient group in which blastocyst culture and transfer were performed, and discusses the advantages and disadvantages of introducing blastocyst transfer in a clinic. Twenty-six patients who had failed to achieve a pregnancy in previous in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatments were offered the choice of a fresh cycle with culture to the blastocyst stage. Of the 26 patients who elected to attempt blastocyst culture, 11 opted to have transfer on day 2 or day 3 due to low numbers of embryos. Of the 15 patients who proceeded to blastocyst culture, 46.2% of the embryos cultured reached the blastocyst stage or later and eight of the patients achieved a clinical pregnancy. More oocytes were collected in this patient group, hence the chances of obtaining blastocysts were higher. Offering blastocyst culture to patients with a reasonable chance of success who have had previous multiple assisted reproduction failures is an acceptable way of introducing blastocyst culture into practice.

Abstract
OBJECTIVE To identify the epidemiological characteristics of infants with biliary atresia in England and Wales, since centralisation of its management in 1999. METHODS The care of infants with biliary atresia (BA) in England and Wales is centralised to only three centres. All infants (treated from January 1999 to December 2006) were identified from a prospective national database; demographic details were ascertained from medical records and compared between two groups based on presumed aetiology (isolated biliary atresia (IBA) and developmental biliary atresia (DBA) (for example, syndromic infants, biliary atresia splenic malformation, cystic biliary atresia)). RESULTS There were 302 (133 male (44%)) infants with BA that could be divided into IBA (n = 219, 73%) and DBA (n = 76, 25%). The overall incidence was 0.58/10 000 (1 in 17,049) live births with marked regional differences along a north-west/south-east axis varying from 0.38 (north-west England) to 0.78 (south-east England)/10,000 live births (OR 2.05 (95% CI 1.26-3.41); p = 0.002). The commonest month of birth was September with December being the least common, although there was no evidence for significant seasonal variation (p = 0.2). Infants with DBA were more likely to be female (p<0.001), of white background (p = 0.01), first-born (p = 0.04) and to be formula-fed (p = 0.07). Infants of south Asian origin came to surgery at an older age (59 (IQ 45-75) versus 52 (IQ 42-65) days; p = 0.03). CONCLUSIONS There is a remarkable variation of incidence of biliary atresia within England and Wales, some of which may have been caused by factors related to a different aetiological and racial background.

Abstract
An 11-year-old boy with irreversible intestinal failure secondary to chronic intestinal pseudo-obstruction (CIPO) and intestinal failure-associated liver disease (IFALD) underwent a combined en bloc reduced liver and small bowel transplantation. He was discharged home after 9 weeks on full oral intake without requiring intravenous nutritional or fluid supplementation. The first episode of mild acute rejection, which occurred 18 months after transplantation, was successfully treated with steroids. An episode of rotavirus gastroenteritis led to severe exfoliative rejection of the bowel graft, which was resistant to steroid and Infliximab treatment but responded to OKT3. There was associated Epstein-Barr virus viremia with no evidence of posttransplant lymphoproliferative disease. Another episode of moderate to severe acute liver rejection occurred 5 months later. At the same time, multiple biliary strictures were diagnosed and treated. Persistent clinical symptoms of abdominal pain and increased stomal output as well as atrophy of the ileal mucosa on several biopsies, suggested the possibility of chronic rejection (CR). A second combined whole liver and small bowel transplant was performed. The diagnosis of CR was confirmed on histology of the explanted graft. The postoperative course was severely complicated and 71 days after the retransplantation, the boy died because of respiratory failure and multiorgan failure. In summary, intestinal transplantation can be successfully performed in children with CIPO, giving them the opportunity to be free from total parenteral nutrition. As survival following intestinal transplantation continues to improve, the problem of CR has become increasingly important and the only treatment available is retransplantation, which is associated with poor outcomes.

Abstract
INTRODUCTION Following intestinal transplant (SBT), the early diagnosis and treatment of rejection is a major management aim. The diagnosis of rejection is based on histology of stomal biopsies. Oral gentamycin (2.5 mg/kg) was used for selective decontamination of the digestive system. Our hypothesis was that gentamycin might be absorbed in the presence of graft dysfunction. AIM Our goal was to assess the correlation between serum gentamycin level and the health of the intestinal graft. SUBJECTS AND METHODS Among 33 SBT performed from 1993 to 2005, serum gentamycin levels were performed once weekly or more often when there was a suspicion of rejection. All data were analyzed retrospectively. RESULTS Adequate trough levels were achieved for only 23 patients, six of whom had histologically proven rejection and only one did not have a raised gentamycin content. Five patients with raised levels but no rejection included two with severe intestinal ischemia and three with bowel obstruction/ileus. Four of the five patients required laparotomies. CONCLUSION We concluded that in our study raised serum gentamycin levels were a good predictor of rejection or significant injury to the graft.

Abstract
UNLABELLED The 3-year survival after small bowel transplantation (SBTx) has improved to between 73% and 88%. Impaired venous access for parenteral nutrition can be an indication for SBTx in children with chronic intestinal failure. AIM To report our experience in management of children with extreme end-stage venous access. SUBJECTS The study consisted of 6 children (all boys), median age of assessment 27 months (range, 13-52 months), diagnosed with total intestinal aganglionosis (1), protracted diarrhea (1), and short bowel syndrome (4), of which gastroschisis (2) and malrotation with midgut volvulus (2) were the causes. All had a documented history of more than 10 central venous catheter insertions previously. All had venograms, and 1 child additionally had a magnetic resonance angiogram to evaluate venous access. Five of 6 presented with thrombosis of the superior vena cava (SVC) and/or inferior vena cava. METHODS Venous access was reestablished as follows: transhepatic venous catheters (5), direct intra-atrial catheter via midline sternotomy (4), azygous venous catheters (2), dilatation of left subclavian vein after passage of a guide wire and then placing a catheter to reach the right atrium (1), radiological recanalization of the SVC and placement of a central venous catheter in situ (1), and direct puncture of SVC stump(1). Complications included serous pleural effusion after direct intra-atrial line insertion, which resolved after chest drain insertion (1), displacement of transhepatic catheter needing repositioning (2), and SVC stent narrowing requiring repeated balloon dilatation. OUTCOME Four children with permanent intestinal failure on assessment were offered SBTx, 3 of which were transplanted and were established on full enteral nutrition; the family of 1 child declined the procedure. In the remaining 2 children in whom bowel adaptation was still a possibility, attempts were made to provide adequate central venous access as feeds and drug manipulations were undertaken. One of them received liver and SBTx nearly 3 years after presenting with end-stage central venous access, because attempts to achieve independence from parenteral nutrition had failed. The other child died immediately after a transhepatic venous catheter placement, possibly from a nutritional depletion syndrome as no physical cause of death was found. Direct intra-atrial catheters in transplanted children proved to be adequate for the management of uncomplicated transplantation, although the usual infusion protocol had to be modified considerably, and the lack of access would have been critical if massive blood transfusion had been required during the transplant procedure. CONCLUSION It was possible to reestablish central venous access in all cases. However, this was time consuming and difficult to assemble a skilled team consisting of one of more: surgeon, cardiologist, interventional radiologist, and transplant anesthetist. Small bowel transplantation is easier and safer with adequate central venous access, and we advocate liaison with an SBTx center at an early stage.

Abstract
Hepatic mesenchymal hamartoma is a rare benign tumour in children. It is often large and centrally located in the liver at diagnosis, making surgical resection difficult; thus non-radical resection has been proposed in the past as acceptable management. However, a literature survey and a case with recurrence associated with cytogenetic anomalies suggest that radical liver surgery (resection with a margin of normal liver parenchyma, as for malignant tumour) should be recommended for mesenchymal hamartoma.

Abstract
Rescue in-vitro fertilisation and embryo transfer (IVF-ET) has been used in high response gonadotrophin intrauterine insemination (IUI) cycles to minimise the risks of ovarian hyperstimulation and multiple gestation. Such unplanned IVF treatment increases the cost of treatment. But can this added cost and the risks associated with IVF be justified? We present our experience with this treatment using clinical pregnancy and live birth rates as the primary outcomes. Between 1998 to 2001, 40 women undergoing IUI cycles who over responded (>3 follicles measuring >15 mm in diameter on the planned day of hCG administration) to gonadotrophin were offered the choice of conversion to IVF-ET or cancel the cycle. 17/40 declined rescue IVF/ET and had their cycles cancelled. 23/40 converted to IVF/ET and underwent transvaginal oocyte retrieval. 21/23 had embryo transferred. The clinical pregnancy and live birth rates were 52% and 48%, respectively. Rescue IVF-ET offers excellent clinical pregnancy and live birth rates in high responders. However, affordability can be an obstacle in the utilization of this treatment option.

Fibroids are the most common benign tumours of the pelvis in women, with a prevalence estimated at 20-50%. They are more common towards the end of the reproductive years. There is a racial preponderance, being more common in black than white women. This may relate to the aetiology, which is still poorly understood. Generally, fibroids do not cause symptoms but some sufferers do complain about pressure symptoms, abnormal vaginal bleeding and infertility. For these reasons, myomectomy is often resorted to after failure of medical interventions on the premise that it brings about improvement/cure of symptoms and enhancement of fertility. However, the evidence for these indications for surgery is hazy. An analysis of the 109 medical records of symptomatic patients who had myomectomy over a 5-year period at a tertiary centre revealed the following. Single-symptom presentation in 41 (38%), menorrhagia in 20 (18%) being the most common. Only 52 (48%) patients had medical treatment of one form or another before myomectomy. Additional operative findings included pelvic adhesions, evidence of PID and endometriosis. Thirty-four (31%) had an estimated blood loss 500 ml and 23 of these patients needed blood transfusion. There were four cases of unscheduled hysterectomies due to uncontrollable bleeding. Pyrexia was the most common (38%) postoperative complication followed by superficial wound infection in 5%. We observed improvement of symptoms, assessed over a range of 2-24 months, in 34 cases (68%) in patients without fertility symptoms who accounted for 50 of these women. The symptomatic benefit was less (36%) in the 'infertility group'. Following an observation period of over 12-36 months, 17 patients in the 'infertility group' were lost to follow-up. Two (14%) of the 14 patients who attempted in vitro fertilisation (IVF) were successful. In the non-IVF group, 13 (46%) of the 28 achieved natural conception. These results suggest that symptomatic improvement and fertility enhancement may be possible in some patients with fibroids. In view of the risks and potential failure of treatment associated with myomectomy these results, yet again, support the fact that patients should be properly counselled before embarking on myomectomy and we strongly advocate local data to form the basis of the advice given during the consultation rather than what obtains in the literature.

Abstract
Hepatic epithelioid haemangio-endothelioma (HEHE) is an endothelium-derived tumour of low-to-medium grade malignancy. It is predominantly seen in adults and is unresponsive to chemotherapy. Liver transplantation is an accepted indication when the tumour is unresectable. Hepatic epithelioid haemangio-endothelioma is very rare in children and results after transplantation are not reported. The aim of this study is to review the experience of three European centres in the management of HEHE in children. A retrospective review of all paediatric patients with HEHE managed in three European centres is presented. Five children were identified. Four had unresectable tumours. The first had successful resection followed by chemotherapy and is alive, without disease 3 years after diagnosis. One child died of sepsis and one of tumour recurrence in the graft and lungs 2 and 5 months, respectively, after transplant. Two children who had progressive disease with ifosfamide-based chemotherapy have had a reduction in clinical symptoms and stabilisation of disease up to 18 and 24 months after the use of platinum-based chemotherapy. HEHE seems more aggressive in children than reported in adults and the curative role of transplantation must be questioned. Ifosfamide-based chemotherapy was not effective. Further studies are necessary to confirm if HEHE progression in children may be influenced by platinum-based chemotherapy.

Abstract
BACKGROUND In the last decade, numerous studies have demonstrated concern about the presence of hydrosalpinx and its management in patients undergoing IVF. We evaluated the current management of hydrosalpinx prior to IVF treatment in the UK. METHODS A total of 117 postal survey, anonymous, sealed questionnaires were sent to all IVF centres in the UK, to determine the policy for the management of hydrosalpinx in infertile women prior to IVF treatment. RESULTS There were 88 (75%) responders, of which 80 (91%) indicated that they discussed the effect of hydrosalpinx on IVF outcome. Ten (12%) units did not recommend treatment of hydrosalpinx prior to IVF treatment, while 30 (36%), 27 (33%) and 16 (19%) recommended treatment weakly, strongly and very strongly respectively. The treatment options offered by clinicians were laparoscopic salpingectomy (75%), open salpingectomy (45%), salpingostomy (40%), proximal tubal occlusion (34%), transvaginal songraphic (TVS) aspiration during oocyte collection (23%) and TVS aspiration before oocyte collection (10%). The frequency of use varied from one option of treatment to another. Only 28% of the responders had a protocol or guidelines for the management of hydrosalpinx. CONCLUSIONS More attention should be given to patients with hydrosalpinx prior to IVF treatment and patients should be counselled about the negative effect of hydrosalpinx on IVF outcome. There is a wide variation in the management of hydrosalpinx prior to IVF treatment in the UK and many treatment options may be questionable, as they are not yet based on evidence.

Abstract
Bile ducts of Luschka (also called supravesicular ducts) are small bile ducts in the gallbladder bed. Although they do not drain any liver parenchyma, they can be a source of bile leak or biliary peritonitis after cholecystectomy in both adults and children, as shown in this case report. As a reminder, variations of biliary anatomy in the gallbladder bed and cholecysto-hepatic triangle of Calot, are reviewed.
