RESUMEN

BACKGROUND: The Global Initiative for Children's Surgery group published the Optimal Resources for Children's Surgery (OReCS) document outlining the essential criteria and strategies for children's surgical care in low-resource settings. Limited data exist on subspecialties in pediatric surgery and their contribution to global surgery efforts. The study aimed to evaluate the development of subspecialty units within Chris Hani Baragwanath Academic Hospital (CHBAH) Department of Pediatric Surgery (DPS) from January 1, 2018 to December 31, 2021 using selected OReCS strategies for the improvement of pediatric surgery. METHODS: A retrospective descriptive research design was followed. The study population consisted of CHBAH PSD records. The following data were collected: number of patients managed in PSD subspecialty unit (the units) clinics and surgeries performed, number of trainees, available structures, processes and outcome data, and research output. RESULTS: Of the 17,249 patients seen in the units' outpatient clinics, 8275 (47.9%) burns, 6443 (37.3%) colorectal, and 2531 (14.6%) urology. The number of surgeries performed were 3205, of which 1306 (40.7%) were burns, 644 (20.1%) colorectal, 483 (15.1%) urology, 341 (10.6%) hepatobiliary, and 431 (12.8%) oncology. Of the 16 selected strategies evaluated across the 5 units, 94% were available, of which 16.4% was partly provided by Surgeons for Little Lives. Outcome data in the form of morbidity and mortality reviews for all the units is available, but there is no data for timeliness of care with waiting lists. There were 77 publications and 41 congress presentations. CONCLUSION: The subspecialty units respond to the global surgical need by meeting most selected OReCS resources in the clinical service provided.

RESUMEN

BACKGROUND: The diagnosis of Hirschsprung's disease (HD) by rectal suction biopsy (RSB) has cost implications that could be reduced by ascertaining the optimal number of specimens required. The aim was to audit our experience to optimise cost-effectiveness. METHODS: Medical records of all patients who underwent an RSB between January 2018 and December 2021 were reviewed. In 2020, we transitioned from using the Solo-RBT to the rbi2 system (requiring single-use cartridges). Descriptive statistics were reported and a comparative analysis of the diagnostic efficacy of the Solo-RBT versus the rbi2 system was performed. The cost of consumables was calculated according to the number of specimens submitted. RESULTS: Of 218 RSBs, 181 were first and 37 were repeat. The mean age at biopsy was 62 days (IQR 22-65). An average of two tissue specimens were obtained per biopsy. Of the 181 first biopsies, 151 were optimal and 30 suboptimal. HD was confirmed in 19 (10.5%) of the patients. Amongst biopsies where a single specimen was obtained, 16% were inconclusive, compared to 14% with two specimens and 5% with three specimens. The cartridges for the rbi2 system cost R530. If two cartridges are used at initial biopsy the total cost is double of a single tissue specimen sent for initial biopsy, and two specimens sent for repeat biopsies. CONCLUSION: In a low-resource setting, selecting the appropriate RSB system and obtaining a single specimen is sufficient to diagnose HD. Patients with inconclusive results should undergo a repeat biopsy where two specimens are obtained.

RESUMEN

BACKGROUND: The dress code for surgeons has evolved over time from formal suit-and-tie to crisp white coat, and currently to various forms of smart-casual attire; however, there is no stipulated or rigid uniform guideline. It is important to explore and discuss the various forms of attire in relation to patients' ideals and perceptions of a surgeon. METHODS: An observational study in the form of a paper-based questionnaire was carried out at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), Chris Hani Baragwanath Academic Hospital (CHBAH) and Wits Donald Gordon Medical Centre (WDGMC). Seven questions (Q1-Q7) were posed with various dress categories to select from in each question, namely: formal, smart, smart-casual and scrubs. Descriptive analysis of the survey responses, and the determination of the association between survey responses and a) hospital, b) gender, c) age group was performed. Fisher's exact test was used where the requirements for the chi-square test could not be met. Attire groups with n < 15 were not analysed. The strength of the associations was measured by Cramer's V and the phi coefficient respectively. Data analysis was carried out using SAS v9.4 for Windows. A 5% significance level was used. RESULTS: A total of 387 questionnaires were filled out with a total of 376 fully completed and eligible samples in consenting participants of 18 years and older. In all seven questions, scrubs were the preferred attire. Overall, for Q1-Q5 and Q7, after scrubs, smart was the next most popular attire. For Q6, after scrubs, smart, smart-casual and formal were all popular, indicating some leeway on weekends and public holidays. There was a significant association between each of the responses to the question and hospital (p < 0.0001). At CHBAH, patients preferred scrubs more and smart attire less, compared to CMJAH and WDGMC. At CMJAH, preference for formal attire was greater when compared to the other two hospitals. CONCLUSION: Overall, patients preferred their surgeons to be dressed in scrubs as this attire easily identified surgeons and instilled confidence in the wearer.

RESUMEN

Background. Road traffic accidents (RTAs) are a leading cause of injury and death globally, particularly among children. Pedestrians are most often injured, especially in middle- and low-income countries. The epidemiology, patterns and severity of injuries in children involved in RTAs in our community are hard to obtain. Objectives. To evaluate the aetiological spectrum, injury characteristics and treatment outcomes of paediatric patients involved in RTAs,who presented to Chris Hani Baragwanath Academic Hospital (CHBAH), a tertiary hospital in Soweto, South Africa. Methods. Patients ≤10 years old, who were involved in RTAs and seen at CHBAH, were included in the study. Results. The study was conducted from 20 August 2017 to 31 March 2018, and included the data of 156 patients. Their ages ranged from 13 days to 10 years (65% were boys). Pedestrian vehicle accidents accounted for 78.8% of the injuries, with 60.8% of the children being unaccompanied by an adult. Motor vehicle accidents accounted for 19.2% of the injuries, with 92% of the children being unrestrained in the vehicle. Of the patients, 73.2% (n=112/153) underwent radiography and 44.4% required computed tomography (CT) scans, the majority being CT scans of the brain for suspected head injuries. Soft-tissue injuries accounted for 78.9% of cases, followed mainly by head (39.7%) and limb (16%) injuries. Only 12% of patients required surgical intervention, with 42% of the operations being for orthopaedic injuries. Conclusion. The abovementioned data demonstrate that there is a lack of use of child restraints for children travelling as passengers invehicles, and inadequate supervision of children on and around roads. This study supports other evidence, as it suggests that the paediatric population involved in RTAs is largely injured as pedestrians, and that males tend to be involved in more RTAs than females. The majority of injuries sustained involved the soft tissues, followed by head injuries

RESUMEN

BACKGROUND: South African data on paediatric patients with renal trauma that are usually managed conservatively is scarce. This study aimed to review a 7-year experience of paediatric renal trauma and management. METHODS: A retrospective review of all paediatric admissions with renal injury was conducted in the Department of Paediatric Surgery, University of the Witwatersrand, between 1 January 2012 and 31 December 2018. Data from medical records reviewed included patient age, gender, mechanism of injury, severity of injury, management and length of hospital stay. RESULTS: Thirty-one patients with renal injuries were identified, of which 30 had complete data. Of these cases, 26/30 (87%) sustained blunt renal injuries and 4/30 (13%) were penetrating. The median age at presentation was 6 years, and 60% were females. Three patients had isolated renal injuries, and 23 had concomitant injuries including hepatic (9), thoracic (8), splenic (5), head (4), facial (3) and ureteric (1). Twenty-three patients were managed non-operatively. Two required renal exploration with resultant nephrectomies and one haemodynamically unstable patient died preoperatively. Four patients required operative intervention for concomitant injuries with no renal exploration. Two patients required ureteric stenting. The median length of hospital stay was 7 days (Range: 4-11 days, IQR 7 days). CONCLUSION: Renal injuries in haemodynamically stable patients should be managed non-operatively. A 93% renal preservation rate was achieved in this cohort of patients with nephrectomy performed only in haemodynamically unstable patients with Grade V injuries, in keeping with international norms.

RESUMEN

BACKGROUND: The precise burden of paediatric surgical care in South Africa is unknown. In the absence of epidemiological data, hospital-based study is a first step to gauge the burden and profile of paediatric surgical disease. We aim to describe the profile of pathology, pattern of referrals, and complications of paediatric surgical care at Chris Hani Baragwanath Academic Hospital (CHBAH). METHODS: A 1-year retrospective record review for the period 3/1/2019 to 1/1/2020 was conducted by evaluation of the morbidity and mortality databases of the Department of Paediatric Surgery (DPS). Number of admissions, consultations, complications, and surgeries performed were analysed and classified. RESULTS: A total of 11,932 unique patient encounters occurred. Emergencies (79%, 1841/2329) accounted for the majority of admissions. Trauma accounted for 49% (896/1841) of emergency admissions. Elective surgery constituted 52% (1202/2316) and emergency surgery 48% (1114/2316) of all procedures performed. The emergency department (55%, 1271/2329), outpatients department (19%, 447/2329), and peripheral hospitals (16%, 378/2329) were the source of the majority of admissions. A complication rate of 9% (208/2316) was observed. CONCLUSION: The high-volume subspecialist environment at CHBAH presents the ideal environment for delivery of specialist paediatric surgical services and training. Injury prevention, optimal use of existing resources, and additional physical, human and financial resources are required to meet the existing and predicted future burden of paediatric surgical disease.

RESUMEN

PURPOSE: The neonatal period is the most vulnerable period for a child. There is a paucity of data on the burden of neonatal surgical disease in our setting. The aim of this study was to describe the frequency with which index neonatal surgical conditions are seen within our setting and to document the 30-day outcome of these patients. METHODS: This was a single-centre prospective observational study in which all neonates with paediatric surgical pathology referred to the paediatric surgical unit with a corrected gestational age of 28 days were included. RESULTS: Necrotising enterocolitis was the most frequent reason for referral to the paediatric surgical unit (n = 68, 34.34%). Gastroschisis was the most frequent congenital anomaly referred (n = 20, 10.10%). The overall morbidity was 57.58%. Surgical complications contributed to 18.51% of morbidities. The development of gram negative nosocomial sepsis was the most frequent cause of morbidity (n = 98, 50.78%). Mortality at 30 days was 21.74% (n = 40). Sepsis contributed to mortality in 35 patients (87.5%), 16 of which had gram negative sepsis. CONCLUSION: Gram-negative sepsis was a major contributing factor in the development of morbidity and mortality in our cohort. Prevention and improvement in infection control are imperative if we are to improve outcomes in our surgical neonates.

RESUMEN

BACKGROUND: Traumatic brain injury (TBI) in the paediatric population is a significant contributor to death and disability worldwide. In sub-Saharan Africa, death and disability from TBI are still superseded by infectious disease. Mechanisms of injury differ by region and socioeconomics, but in general, falls, road traffic collisions (RTCs), being 'struck by/against objects' and non-accidental injuries (NAIs) are responsible for most cases. OBJECTIVES: To: (i) quantify the burden of TBI in terms of demographics, causes and severity; (ii) explore resource utilisation regarding length of stay, computed tomography (CT) brain scan use and multidisciplinary participation; (iii) interrogate possible temporal patterns of injury; and (iv) thus identify potential targets for community-based prevention strategies. METHODS: In a 5-year retrospective review of all children aged <10 years admitted with TBI between September 2013 and August 2018, demographics, date of injury, mechanism of injury, severity of TBI based on the Glasgow Coma Scale, and requirement for a CT brain scan were collected for each patient. Outcomes were reported as discharge, transfer or death. Outcomes for children sustaining isolated TBI were compared with those for children sustaining TBI with polytrauma. RESULTS: A total of 2 153 patients were included, with a mean (standard deviation) age of 4.6 (2.7) years and a male/female ratio of 1.7:1. RTCs were the most frequent cause of injury at 59% (80% of these were pedestrian-vehicle collisions), followed by falls at 24%. Mild TBIs accounted for 87% of admissions, moderate injuries for 6%, and severe injuries for 7%. Polytrauma was associated with increased severity of TBI. The cohort had a 2.3% mortality. NAIs accounted for 6% of injuries and carried a 4% mortality. The median (interquartile range) duration of hospitalisation was 1 (1 - 3) days, ranging from <24 hours to 132 days. CT scans were performed on 43% of admitted patients, and 48% of patients had consultations with another medical or allied medical discipline. Injuries were more frequent during the summer months and over weekends. Infants aged <1 year were identified as a group particularly vulnerable to injury, specifically NAI. CONCLUSIONS: Paediatric TBI was demonstrated to be a resource-intensive public health concern. From the results, we identified potential primary prevention targets that could perhaps be incorporated into broader community-based intervention programmes. We also identified a need to study long-term consequences of mild TBI further in our paediatric population.

RESUMEN

The evolution of social behavior depends on genetic changes, yet, how genomic variation manifests itself in behavioral diversity is still largely unresolved. Chromosomal inversions can play a pivotal role in producing distinct behavioral phenotypes, in particular, when inversion genes are functionally associated with hormone synthesis and signaling. Male ruffs exhibit alternative reproductive tactics (ARTs) with an autosomal inversion determining two alternative morphs with clear behavioral and hormonal differences from the ancestral morph. We investigated hormonal and transcriptomic differences in the pituitary and gonads. Using a GnRH challenge, we found that the ability to synthesize testosterone in inversion carriers is severely constrained, whereas the synthesis of androstenedione, a testosterone precursor, is not. Inversion morphs were able to produce a transient increase in androstenedione following the GnRH injection, supporting the view that pituitary sensitivity to GnRH is comparable to that of the ancestral morph. We then performed gene expression analyses in a second set of untreated birds and found no evidence of alterations to pituitary sensitivity, gonadotropin production or gonad sensitivity to luteinizing hormone or follicle-stimulating hormone across morphs. Inversion morphs also showed reduced progesterone receptor expression in the pituitary. Strikingly, in the gonads, inversion morphs over-expressed STAR, a gene that is located outside of the inversion and responsible for providing the cholesterol substrate required for the synthesis of sex hormones. In conclusion, our results suggest that the gonads determine morph-specific differences in hormonal regulation.

RESUMEN

History provides wonderful insights into how society develops, providing innumerable lessons that can be used as individuals and institutions move into the future. The history of medicine provides particular value, yet it is so often overlooked by the present, society taking for granted what has often been a tremendous struggle to achieve. This overview of the history of paediatric surgery at the University of the Witwatersrand provides amazing insights into what has been achieved in a period spanning three centuries.

RESUMEN

BACKGROUND: Ten per cent of children who present with abdominal pain at an emergency department are diagnosed with acute appendicitis. The diagnosis of which relies on clinical acumen, but addition of tests such as measurement of the white cell count (WCC) and C-reactive protein (CRP) are needed to decrease the morbidity associated with inappropriate surgical management. This study evaluates the sensitivity, specificity and accuracy of the WCC and CRP separately and when used in combination and evaluates whether an increased WCC and CRP are associated with complicated appendicitis. METHOD: A retrospective record review of all paediatric patients who underwent appendicectomy between June 2010 and December 2016 was conducted. Demographic data, the WCC, CRP and histology results were reviewed. RESULTS: 763 records were reviewed. The sensitivity and specificity of the WCC were 69.6% and 43.1% respectively and of the CRP were 95.4% and 24.5% respectively. The sensitivity was higher when both the CRP and WCC were elevated (97.47%). A normal WCC and CRP had a specificity of 98%, with an odds ratio of 8.69 of a patient not having appendicitis. There was a borderline significance between the WCC and the presence of acute appendicitis (p = 0.0494). The CRP was significant in patient with acute appendicitis (p < 0.0001). The WCC and CRP between uninflamed appendix specimens, uncomplicated appendicitis and complicated appendicitis was significant. CONCLUSION: Both increasing CRP and WCC correlates with an increased likelihood of the presence of complicated appendicitis. The chance of a patient having appendicitis with both normal WCC and CRP is low.

RESUMEN

BACKGROUND: Living donor liver transplantation (LDLT) plays a crucial role in liver transplant programmes, particularly in regions with a scarcity of deceased donor organs and especially for paediatric recipients. LDLT is a complex and demanding procedure which places a healthy living donor in harm's way. Donor safety is therefore the overriding concern. This study aimed to report our standardised approach to the evaluation, technical aspects and outcomes of LDLT donor hepatectomy at Wits Donald Gordon Medical Centre. METHOD: The study population consisted of all patients undergoing LDLT donor hepatectomy since the inception of the programme in March 2013 until 2018. Sixty five living donor hepatectomies were performed. Primary outcome measures included donor demographics, operative time, peak bilirubin, aspartate and alanine transaminase levels postoperatively, length of hospital stay and postoperative complications using the Clavien-Dindo classification. RESULTS: The majority of the donors were female, most were parents with mothers being the donor almost 85% of the time. The median operative time was 374 minutes with a downward trend over time as experience was gained. The median length of hospital stay was 7 days. There was no mortality and the complication rate was 30% with the majority being minor (Grade 1). CONCLUSION: Living donor liver transplant from adult-to-child has been successfully initiated in South Africa. Living donor hepatectomy can be safely performed with acceptable outcomes for the donor. Wait-list mortality however remains unacceptably high. Expansion of LDLT as well as real change in deceased donor policy is required to address this issue.

RESUMEN

BACKGROUND: Despite the widespread use of Kasai Portoenterostomy (KPE) for biliary atresia, more than two thirds of these patients require liver transplant. Liver transplantation is not widely available in South Africa, and Wits Donald Gordon Medical Centre is one of two centres performing paediatric liver transplantation in the country, and the only centre performing living related donor transplants. METHOD: A retrospective review was performed at the centre. Demographic data were collected, and tabulated. Survival analysis was performed using the Kaplan Meier method. Complication rates were categorised into biliary, vascular and enteric, and classified as early and late. RESULTS: Sixty-seven first time liver transplants were performed for biliary atresia at WDGMC from 2005 to 2017. Sixty-nine percent were female patients and thirty-one percent were male patients. Forty-eight percent of patients under the age of 5 years had a z-score of -2 or worse for mid upper arm circumference (MUAC). One year overall survival of the cohort is 84.5%, and overall graft survival is 82.9%. Overall mortality was 22%, with infection being the most common cause of death. CONCLUSION: Early referral of all patients with biliary atresia to a paediatric liver transplant centre is essential for early assessment of indications, and medical and nutritional optimisation of patients. Primary liver transplant should be considered for a select group of patients with unique clinical indications.

RESUMEN

Background. There are no recently published data on the incidence and demographics or perforation rates of paediatric patients from our local population presenting with acute appendicitis. Objective. To show the age and gender distribution of paediatric patients presenting with acute appendicitis within our communities, as well as demonstrating the incidence of perforated acute appendicitis in our paediatric population. Method. The study is a retrospective record review of all paediatric patients who presented with acute appendicitis to the Department of Paediatric Surgery at both Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), and Chris Hani Baragwanath Academic Hospital (CHBAH) from June 2010 to September 2015. Data collected included all demographic data as well as histology results of patients who underwent appendectomies. Results. The total numbers of patients included in the study were 544; 234 at CHBAH, and 311 at CMJAH. The male-to-female ratio was 1.58:1. The mean age for presentation at both hospitals combined was 8.76 years. We found that 13.41% of paediatric patients with acute appendicitis in this cohort were under the age of 6 years. A histological review showed that 50.1% of patients in our cohort presented with complicated appendicitis, and we had a negative appendectomy rate of 8.4%. Histological results of patients under the age of 6 years revealed a higher negative appendicectomy rate of 11.4%. However, the incidence of complicated appendicitis in this age group was only 45.7%, which is lower than that reported in the literature. Three patients were found to have Enterobius vermicularis in the lumen of the appendix, and Ascaris ova were identified in one patient. Histology revealed a low-grade mucinous neoplasm in one patient. Conclusion. Acute appendicitis occurred at a median age of 8.76 years in our study population, with a male-to-female ratio of 1.58:1. We found that acute appendicitis occurred relatively more frequently in our patients under the age of 6 years compared with the incidence of acute appendicitis in this age group published elsewhere. Complicated appendicitis occurred in 50.1% of our patient population, with an increased frequency of perforated appendicitis occurring in our male population. However, complicated appendicitis occurred in only 44.7% of our patients below the age of 6 years, which is in stark contrast to published literature. Helminthic infections were rare associated pathogens in our study, and an unlikely underlying pathogen of acute appendicitis in our population

RESUMEN

BACKGROUND: Liver transplantation is the standard of care for the treatment of liver failure worldwide, yet millions of people living in sub-Saharan Africa remain without access to these services. South Africa (SA) has two liver transplant centres, one in Cape Town and the other in Johannesburg, where Wits Donald Gordon Medical Centre (WDGMC) started an adult liver transplant programme in 2004. OBJECTIVES:  To describe the outcomes of the adult liver transplant programme at WDGMC. METHODS:  This was a retrospective review of all adult orthotopic liver transplants performed at WDGMC from 16 August 2004 to 30 June 2016 with a minimum follow-up of 6 months. The primary outcome was recipient and graft survival and the effect of covariates on survival. Kaplan-Meier survival analysis included all adults who underwent their first transplant for end-stage liver disease (ESLD) (N=275). Proportional hazards regression analysis using hazard ratios (HRs) was conducted to determine which covariates were associated with a significantly increased risk of mortality. RESULTS:  A total of 297 deceased-donor liver transplants were performed during the study period; 19/297 (6.4%) were for acute liver failure (ALF) and the remainder were for ESLD. The median age of recipients was 51 years (interquartile range 41 - 59), and two-thirds were male. The most common cause of ESLD was primary sclerosing cholangitis. The median follow-up was 3.2 years, and recipient survival was characterised in the following intervals: 90 days = 87.6% (95% confidence interval (CI) 83.1 - 91.0), 1 year = 81.7% (95% CI 76.6 - 85.8), and 5 years = 71.0% (95% CI 64.5 - 76.5). Allograft survival was similar: 90 days = 85.8% (95% CI 81.1 - 89.4), 1 year = 81.0% (95% CI 75.8 - 85.2), and 5 years = 69.1% (95% CI 62.6 - 74.7). The most significant covariates that impacted on mortality were postoperative biliary leaks (HR 2.0 (95% CI 1.05 - 3.80)), recipient age >60 years at time of transplant (HR 2.06 (95% CI 1.06 - 3.99)), theatre time >8  hours (HR 3.13 (95% CI 1.79 - 5.48)), and hepatic artery thrombosis (HR 5.58 (95% CI 3.09 - 10.08)). The most common infectious cause of death was invasive fungal infection. CONCLUSIONS:  This study demonstrates that outcomes of the adult orthotopic liver transplant programme at WDGMC are comparable with international transplant centres. Management of biliary complications, early hepatic artery thrombosis and post-transplant infections needs to be improved. Access to liver transplantation services is still extremely limited, but can be improved by addressing the national shortage of deceased donors and establishing a national regulatory body for solid-organ transplantation in SA.

RESUMEN

BACKGROUND: Anorectal malformations (ARMs) represent a significant surgical load in South African (SA) paediatric surgical centres. Surgical treatment of ARMs may be associated with postoperative complications owing to the nature of surgical procedures necessary in the neonatal and infant period. HIV and its effect on the immune response compound postoperative surgical complications. The impact of HIV exposure and its effect on the child's immune status, independent of the child's HIV status, has yet to be studied in the surgical population. OBJECTIVES: To assess the incidence of complications in our population of ARM patients and to explore whether these were increased in HIV-exposed but serologically negative children compared with HIV-unexposed children. METHODS: This was a prospective study of all patients presenting with ARMs to the paediatric surgery units attached to the University of the Witwatersrand, Johannesburg, SA. Specifically, exposure to an HIV-positive mother, patient HIV status and presence of surgical complications were documented. Data were analysed for the period August 2016 - September 2017. RESULTS: A total of 50 children were included (none were excluded); 19 (38%) were HIV-exposed but none were HIV-positive, and 28 (56%) were male and 22 (44%) female. Seventy-six operative procedures were performed, with 27 operative complications. In the HIV-exposed group, 68% of patients experienced operative complications, compared with 45% in the unexposed group (p=0.1); 50% of the HIV-exposed patients who had stoma formation experienced complications, compared with 20% in the unexposed group (p=0.08). CONCLUSIONS: The incidence of postoperative infectious complications in HIV-exposed patients was higher than in HIV-unexposed patients. The incidence of postoperative complications in HIV-unexposed patients parallels that in the international literature, except in the posterior sagittal anorectoplasty groups. It remains critically important to follow stringent perioperative protocols for infection prevention and aggressively treat any infection that arises, particularly in patients born to HIV-positive mothers, regardless of the patient's HIV status.

RESUMEN

BACKGROUND: Without timely surgical intervention, most children with biliary atresia (BA) are not expected to live beyond 2 years of age. The initial intervention, the Kasai hepatoportoenterostomy (KPE), aims to achieve biliary drainage. Liver transplantation (LT) is performed if jaundice fails to clear or when biliary cirrhosis occurs. In under-resourced South African (SA) academic state hospitals, KPE procedures are the standard of care for the majority of children with BA, but LT is becoming more routinely available. OBJECTIVES: To describe the outcomes of children with BA undergoing KPE, and to identify presenting clinical, laboratory and histological features that were associated with a more favourable outcome. METHODS: All children with BA who underwent KPE between January 2009 and June 2012 at the Johannesburg academic-hospital complex were included. Clinical and laboratory parameters, including paediatric end-stage liver disease (PELD) score at the time of KPE, liver histology fibrosis score, clearance of jaundice at 6 months and 24-month survival were determined. RESULTS: Of 70 children with BA diagnosed during the study period, 43 (61.4%) underwent KPE, but only 12 (27.9%) achieved early resolution of jaundice. By 24 months, 14 (32.6%) of 43 children undergoing KPE were alive with their native liver, and 2 (4.7%) other children underwent LT. PELD score <15 and early resolution of jaundice, but not age at surgery or histological fibrosis score, predicted a favourable outcome. CONCLUSION: Children with BA undergoing KPE in SA state hospitals have a poor prognosis. The PELD score at the time of KPE best predicts 24-month survival.

RESUMEN

BACKGROUND: Portal hypertension is a common and potentially devastating condition in children. Notwithstanding advances in the nonsurgical management of portal hypertension, surgery remains an important treatment modality in select patients. We report here on our experience in the past 12 years. OBJECTIVES: To describe the profile of, indication for, and complications of shunt surgery in children with portal hypertension. METHODS: Twelve children underwent shunt surgery between 2005 and 2017. Patient records were reviewed. RESULTS: Fourteen procedures were performed on 12 patients during the study period. The median age at surgery was 6.5 (range 1 - 18) years. Six patients were male. Gastrointestinal bleeding that was not amenable to endoscopic control was the most common indication for surgery. Portal vein thrombosis was the most common cause of portal hypertension in our series (n=11). Two-thirds (8/12) of all patients had an identifiable underlying risk factor for portal vein thrombosis. One-third of all patients (4/12) underwent a meso-portal bypass procedure (Rex shunt), while 58% (7/12) were managed with a distal splenorenal shunt. All patients received postoperative thromboprophylaxis. We experienced a single mortality, 1 patient experienced shunt thrombosis that required revision shunt surgery, and 2 patients experienced anastomotic strictures, with one being managed with revision surgery and the other currently awaiting radiological venoplasty. CONCLUSIONS: Surgery is a safe and important tool in the management of children with non-cirrhotic portal hypertension and those with sufficient hepatic reserve who fail to respond to more conservative methods for the treatment of side effects of portal hypertension.
