    Four decades of conjoined twins at Red Cross Children's Hospital - lessons learned
    (Health and Medical Publishing Group, 2006) Rode, H; Cywes, S; Lawrenson, J; Numanoglu, A; Fieggen, A G; Brown, R A; Davies, M R Q; Hewitson, J P; Hoffman, E B; Jee, L D; Mann, M D; Matthews, L S; Millar, A J W; Peter, J C; Thomas, J; Wainwright, H
    Conjoined twins represent a rare but fascinating congenital condition, the aetiology of which remains obscure. Over the past four decades, the paediatric surgeons at Red Cross Children's Hospital have been involved in the management of 46 pairs of conjoined twins, of which 33 have been symmetrical and 12 asymmetrical. Seventeen symmetrical twins have undergone separation with 22 children (65%) surviving; all of the live asymmetrical twins survived separation. We describe the important features of this unique cohort, outline our approach to management and present the results of this approach. We consider some of the ethical and moral dilemmas we have confronted, and discuss the prenatal diagnosis, obstetric implications and postnatal care of these children, including the relevant investigations and anaesthetic and surgical management. Specific aspects related to the cardiovascular system, hepatobiliary and gastrointestinal tracts, urogenital tract, central nervous system and musculoskeletal system are highlighted.

    Intracranial endoscopy
    (Health and Medical Publishing Group, 2006) Figaji, A A; Fieggen, A G; Semple, P L; Peter, J C
    In modern neurosurgery there has been a strong trend towards the use of minimally invasive techniques, one of which is intracranial endoscopy. Endoscopic third ventriculostomy (ETV) is the commonest procedure performed; it is used to treat hydrocephalus caused by an obstruction to the ventricular system anywhere distal to the mamillary bodies of the third ventricle. The obstruction is bypassed by a stoma created in the floor of the third ventricle, allowing cerebrospinal fluid (CSF) to flow freely into the subarachnoid space. Endoscopy can also be used for the fenestration of various intracranial cysts, intraventricular biopsy, the placement and retrieval of ventricular catheters, the removal of small intraventricular lesions, and improved visualisation in microsurgical operations. At Red Cross Children’s Hospital and Groote Schuur Hospital endoscopy has become an indispensable tool in the management of a wide range of neurosurgical conditions. As experience has accumulated worldwide, a better understanding of the benefits and limitations of endoscopy in diverse circumstances has emerged.

    Paediatric epilepsy surgery in a middle-income country: the red cross war memorial children's hospital experience
    (2023) Louw, Lizet; Enslin, Johannes; Wilmshurst Joanne; Fieggen, A G
    Purpose While epilepsy surgery has been shown to reduce seizure frequency and severity and even cures seizures in children with drug-resistant epilepsy, data from middle-income countries (MIC) are lacking. Method This study is a retrospective review of children with drug-resistant epilepsy who underwent surgical treatment at Red Cross War Memorial Children's Hospital (RCWMCH) between 1 January 2000 and 31 December 2021 (HREC: 140/2020). Results During the 21-year study period, 60 patients underwent epilepsy surgery for drugresistant epilepsy. The median age of the children was seven years (IQR 4.81-10.27years) at the time of surgery, with a male predominance of 33 patients. The most common surgical procedure performed was an anterior temporal lobectomy for temporal lobe epilepsy in 19 cases (31.7%), followed by peri-insular hemispherotomy in 9 cases (15.0%) and frontal lobectomy in 8 cases (13.3%). Of the 60 patients, complete records were available for 55 patients noting complications in 11 (20.0%), of which 4 cases (7.3%) had major complications. Notably, 2 patients (3.6%) had new-onset psychiatric symptoms. The long term outcomes after surgery showed 1-year seizure freedom in 32 patients (58.2%); among these, 21 patients (38.2%) could stop ASM one year after surgery, 17 patients (30.9%) had a recurrence of their seizures, and three had to restart ASM after 2-3 years. Eight patients (14.5%) required repeat surgery. The one-year-Modified Engel scoring for the study population was: 1-A in 52.7%, I-B in 3.6%, I-C in 1.8%, II-A in 15.8%, III-A in 10.9%, IV-A in 3.6% and IV-B in 10.9%. The most common histological finding in anterior temporal lobectomy (ATL) was focal cortical dysplasia (FCD), found in 11 patients (57.9%). The periinsular hemispherotomy (PIH) cases had equal numbers of FCD and Rasmussen's encephalitis in 4 patients (44.4%). The number of FCD in this series is much higher than in international data. Conclusion Epilepsy surgery is an effective and attainable intervention for drug-resistant epilepsy in the paediatric population despite limited resources and challenging aetiological profiles. Low complication rates were comparable to international data, with good seizure freedom outcomes.

    Surgical treatment for 'brain compartment syndrome' in children with severe head injury
    (Health and Medical Publishing Group, 2006) Figaji, A A; Fieggen, A G; Argent, A; Peter, J C
    OBJECTIVES: Traumatic brain injury accounts for a high percentage of deaths in children. Raised intracranial pressure (ICP) due to brain swelling within the closed compartment of the skull leads to death or severe neurological disability if not effectively treated. We report our experience with 12 children who presented with cerebral herniation due to traumatic brain swelling in whom decompressive craniectomy was used as an emergency. DESIGN: Prospective, observational. SETTING: Red Cross Children's Hospital. SUBJECTS: Children with severe traumatic brain injury and cerebral swelling. OUTCOME MEASURES: Computed tomography (CT) scanning, ICP control, clinical outcome. RESULTS: Despite the very poor clinical condition of these children preoperatively, aggressive management of the raised pressure resulted in unexpectedly good outcomes. CONCLUSION: Aggressive surgical measures to decrease ICP in the emergency situation can be of considerable benefit; the key concepts are selection of appropriate patients and early intervention.
