Several of the conditions can be diagnosed before birth and referred to the UCLH Tertiary Fetal Medicine Unit, where they will have further detailed ultrasound and MRI scans, and will be counselled by the FMU consultants and surgeons from Great Ormond Street, where appropriate. Invasive prenatal diagnosis including karyotyping and microarray of amniocentesis or chorionic villus sampling is available. Prenatal genetic counselling is also available integrated with GOSH genetics service. Dependent on the fetal diagnosis women either deliver at their booking hospital, or have an in utero transfer to UCLH for delivery eg gastroschisis, exomphalos, CDH, where neonatology consultant input is needed at birth. After delivery, these infants will then be transferred to either the surgical ward or to the Neonatal Intensive Care Units at GOSH. Other infants and children will be referred postnatally and have advanced imaging and other diagnostic methods. Children with failed primary treatments (e.g. long-gap oesophageal atresia) are also referred here for complex and/or rescue surgery. Great Ormond Street has specialist paediatric care for all aspects of care of infants and children with rare congenital and acquired gastroenterological and surgical anomalies. The Core specialities listed include Intensive Care, Radiology, Interventional Radiology, General Surgery, Gastroenterology, Dietetics, Pharmacy, Anaesthesia, Respiratory Medicine, Histopathology . In addition, other specialities are available as required, for example, neurology, oncology, metabolic, endocrine, cardiology, other surgical specialities, genetics, immunology, physiotherapy, speech and language therapy. Hence every patient has their care fully covered within the Health Care Provider's Institution, either as an in-patient or as out-patient, with only a few exceptions. There is a strong, cohesive multidisciplinary approach to care with many MDT meetings and clinics for these rare conditions. The expertise of the Health Care Provider in the area is very extensive including in advanced treatment techniques such as minimally invasive approaches , and in addition, partnership with University College London Institute of Child Health provides access to cutting edge research facilities and opportunities for translational research, including first-in-man studies within the appropriate regulatory framework. Follow-up continues long term throughout childhood and appropriate transition is arranged when the patient approaches 16-18 years of age. There are strong links to the adolescent gastroenterology unit at University College London Hospital which provides continuity of care throughout and beyond the transition process for many of these patients. There are also links with adult surgical teams and services at the Royal Free Hospital (pancreatic) and Imperial (complex oesophageal) for appropriate conditions to ensure continuity and life-long specialist care.
