Liver transplantation for children--the Red Cross Children's Hospital experience.

UNLABELLED: Liver transplantation for infants and children has been available in South Africa at a single centre, the only established service in Sub-Saharan Africa, for more than a decade. Current concerns have shifted from an initial target of early post-transplant survival to quality of life in the long-term. MATERIALS AND METHODS: Since 1985, 225 infants and children have been assessed, with 146 accepted for transplantation. Sixty-nine have had 71 orthotopic liver transplants (OLTx). Biliary atresia was the most frequent diagnosis (54%) followed by acute liver failure (ALF) (15%). Waiting list mortality has remained high (23%), particularly for the ALF group (50%). Forty-three were reduced size transplants with donor: recipient weight ratios ranging from 2:1 to 11:1. Twenty-seven were <10 kg. RESULTS: Fifty (74%) survive 1 month-12 years post-transplant. Actuarial survival after 1996 since HBV core antibody positive donor livers were refused and prophylactic IV ganciclovir used has been >82%. Early post-OLTx mortality was low (5%), one primary non-function, one IVC thrombosis, one PV thrombosis, but late morbidity and mortality (20%) was mainly due to viral infection: de novo hepatitis B (five patients, three deaths), EBV-related post-transplantation lymphoproliferative disease (PTLPD) (eight patients, six deaths) and CMV disease (11 patients, five deaths). Tuberculosis prophylaxis, required in six cases, resulted in major morbidity in two and mortality in one. Poor compliance played a significant role in seven deaths. Hypertension requiring medication along with some compromise of renal function has been present in all but two patients. However, all those of school-going age (25) attend school normally and remain in good health and only three of the survivors have abnormal liver function tests. CONCLUSIONS: Successful liver transplantation is possible in a developing country with limited resources. Scarcity of virus-free donors (HBV and HIV) leading to waiting list mortality and infrequent re-transplantation along with long-term consequences of immunosuppression (infection, lymphoma and renal toxicity) remain problems. Intense education of the caregiver and close follow-up, particularly of those living at long distances has partly addressed the compliance problem.

The effects of war on children in Africa.

There is no doubt that the effects of war extend to the most vulnerable members of society, including children. Although armed conflicts occur throughout the world, the African continent seems to be a particular background for civil and international wars. The aim of this study was to identify causes of conflict in Africa and to evaluate the effect of war on children and their health in order to make practical recommendations to health care workers dealing with children in the setting of war. All articles written in the past 5 years concerning "war" and "children" were identified by means of a literature search and internet review. Contrary to common belief, the causes of conflict are complicated and multi-factorial. The effects of war on childhood are disastrous and include severe negative effects on general paediatric health status. Short-term recommendations for health care workers working with children in war include supply of emergency medical infrastructures, basic health care, rehabilitation and education. Long-term recommendations include orchestrating the relief and support efforts from both national governments and international non-profit organisations and speeding up of economic recovery. The causes of conflict in Africa are complex and unlikely to be resolved soon. The effects of war on children are horrendous in many ways, but can be limited by providing timely and appropriate health care.

Unusual intestinal sequelae after operations for Ascaris lumbricoides infestation.

Two children with severe bowel sequelae distal to the site of an Ascaris lumbricoides bowel obstruction are reported. It is postulated that these resulted from inflammatory reaction to toxic decomposition products of disintegrating worms. Surgery should be modified in the presence of bowel-wall injury distal to the site of ascarid worm - bolus obstruction.

The South African experience with ingestion injury in children.

INTRODUCTION: The Red Cross Children's Hospital is the only children's hospital in South Africa. It has a dedicated trauma unit for all children under the age of 13 and serves a population of approximately 2 million inhabitants. As part of the Child Accident Prevention Foundation program we have kept a database of all children treated for trauma in our hospital since 1991. Presently, we have over 88,000 entries in our database. AIM: To study our experience with ingested foreign bodies in children. MATERIALS AND METHODS: A retrospective study was performed using the CAPFSA database of a total of 3677 patients presenting with foreign bodies. The hospital folders were searched using a standardised data extraction form. Only foreign bodies aspirated or ingested were included. RESULTS: To date, 241 folders have been analysed. DEMOGRAPHICS: Both sexes were equally affected (boys 49%). Age ranged between 0 and 12 years, although there was only one child under the age of 1. At the age of 3 years there was a peak in incidence (24% of all cases). Nature of ingested object: Although the objects were from a range of materials, most were metal (40%) or plastic (23%). The most commonly ingested object was a coin (28%), a ball (20%) or bone (8%). The size ranged from 0.1 to 3 cm (as measured by virtual ring), the most common size of an ingested foreign body was 0.5 cm. Anatomical site: The most common anatomical site of impaction was the nose (41%), followed by the oesophagus (20%), the stomach (14%) and bowel (11%). Other anatomical sites included hypopharynx, nasopharynx, bronchus, larynx and oral cavity. Severity of symptoms: Only 0.4% of our cases were assessed as being severe, 14% as moderate, and 44% as mild. Forty-two percent (42%) had no symptoms. Removal: Fifty-seven percent (57%) of ingested foreign bodies were removed surgically, 19% were left in situ, 14% spontaneously dislodged and only 1% was removed by Foley catheter manipulation. CONCLUSION: A presentation with a foreign body is quite common in our patient population, representing approximately 4.2% of all our cases. The majority of ingested foreign bodies produced mild or no symptoms, needed surgical removal and had no complications.

Malrotation and volvulus in infancy and childhood.

The subject of malrotation and midgut volvulus in infancy and childhood is reviewed from the perspective of experience with 138 patients evaluated in a published series and a further 82 cases seen since. Embryology, historical aspects, clinical presentation, investigation, surgery, and outcome are discussed. The diagnosis of malrotation and volvulus should always be kept in mind when assessing any infant or child with symptoms of vomiting and pain, particularly when the vomiting is bile-stained. The diagnosis cannot be excluded if diarrhea is present, when clinical findings are bland, or even with normal abdominal radiographs. A contrast meal and follow-through should be done and, if correctly interpreted, should be diagnostic. Ultrasound examination may be helpful but is not secure enough to exclude the diagnosis. Laparotomy or laparoscopy is the only way to be sure. Malrotation with its propensity for volvulus is truly a time bomb lying within.

Evisceration through multiple abdominal wall defects following blunt abdominal injury.

We report an unusual case of a posttraumatic evisceration of small and large bowel through 2 holes in the anterior abdominal wall after a motor vehicle accident. Prompt adequate management consists of reestablishing the perfusion of the eviscerated organ if the blood supply is compromised, performing a full laparotomy to exclude intra-abdominal organ injury and meticulous cleaning of the eviscerated organs before reducing them in the abdomen and closing the abdomen in layers.

Surgical services for children in developing countries.

There is growing evidence that childhood surgical conditions, especially injuries, are common in developing countries and that poor care results in significant numbers of deaths and cases of disability. Unfortunately, however, surgical care is not considered an essential component of most child health programmes. Strategies for improving paediatric surgical care should be evidence-based and cost-effective and should aim to benefit the largest possible number of children. The most likely way of achieving policy change is to demonstrate that childhood surgical conditions are a significant public health problem. For paediatric purposes, special attention should also be given to defining a cost-effective package of surgical services, improving surgical care at the community level, and strengthening surgical education. Surgical care should be an essential component of child health programmes in developing countries.

Y-V advancement antropyloroplasty for corrosive antral strictures.

Accidental corrosive ingestion by children can result in damage to the oesophagus and stomach. With progressive scarring and fibrosis luminal obstruction occurs. Gastric fibrosis typically results from acid ingestion and occurs in the antrum because of pooling of the corrosive agents at that site. The antral stricture presents with symptoms of progressive outlet obstruction that may take up to 3 years to become clinically apparent. Surgery is necessary to bypass this obstruction. We describe three patients in whom we have successfully utilised a Y-V advancement antro-pyloroplasty as corrective surgery for corrosive antral strictures. The procedures required little dissection and two could be done early in the evolution of the stricture. Antro-duodenal patency was maintained on follow-up.

Fatal hypernatraemia after hypertonic saline irrigation of hepatic hydatid cysts.

A 7-year-old boy with hepatic hydatid cysts developed fatal hypernatraemia after surgery for cyst removal where 20% hypertonic saline (HS) was used as a scolicidal agent. Symptoms of generalised seizures, tachycardia, and hypotension developed within 6 h of surgery. Serum electrolytes confirmed hypernatraemia (170 mmol/l) and hyperchloraemia (141 mmol/l). Despite attempts at resuscitation, he died 20 h later. The literature is reviewed, emphasising the potential dangers of the use of HS and the clinical presentation and appropriate management of hypernatraemia.

Anal achalasia after pull-through operations for Hirschsprung's disease -- preliminary experience with topical nitric oxide.

INTRODUCTION: Following definitive pull-through for Hirschsprung's disease (HD), a minority of patients develop constipation, incontinence and enterocolitis. The cause for these symptoms in some of the patients is believed to be "internal sphincter achalasia" related to abnormal innervation of the sphincter, with an absent anorectal relaxation reflex. Transanal myectomy, posterior sagittal rectal myectomy, anal dilatation and even intrasphincter injection of botulinum toxin have been used to solve this problem. Nitric oxide (NO) has been identified as the chemical messenger of the intrinsic non-adrenergic, non-cholinergic pathway mediating relaxation of the normal internal anal sphincter when applied topically. BACKGROUND/PURPOSE: To evaluate the effect of topical isosorbide dinitrate (DTN) applied to the anus and its role in the management of patients with HD after pull-through who have ongoing difficulties in stool evacuation. MATERIAL AND METHODS: Four children, aged 2, 5, 7 and 13 years, who all underwent the Soave operation for Hirschsprung's disease, were assessed. Three patients had recurrent episodes of enterocolitis, and all had symptoms of difficulty in rectal/colonic evacuation. Conservative treatment of repeated anal dilatation under anaesthesia had failed to improve symptoms. A rectal myectomy and conversion of Soave to Duhamel procedure had been done in 2 without significant improvement in symptoms. In all patients, ano-rectal manometry was performed before and after application of DTN paste (1 mg/kg/day in two separate doses) which was continued for a minimum period of 3 weeks. Results. Marked symptom improvement was noted in all 4 children. On manometric assessment the median maximum pressure (pre-DTN application) was 165 mm Hg (range 96 - 250), the median sphincter length 2.7 cm (range 2.3 - 3.1) and the high-pressure zone (HPZ) median length 1.6 cm (range 1.2 - 2.1). After application of DTN paste, the maximum pressure dropped by a median of 88 mm Hg (range 46 - 90), total sphincter length shortened to a median of 2.1 cm and the HPZ by a median total length of 1.4 cm (range 0.01 - 0.9). In addition, vector volume was reduced by a median of 59 % (range 40.5 - 77). CONCLUSION: From these results, it is evident that DTN paste is not only an adjunct in the investigation, but can also be used as a temporary form of treatment of obstructive symptoms in Hirschsprung's disease patients.

Congenital solitary intestinal fibromatosis.

Neonatal intestinal obstruction due to a tumour is rare. We report a six-day-old male neonate who presented with abdominal distension and vomiting. Laparotomy revealed colonic obstruction caused by a stenosing fibrotic lesion in the proximal transverse colon. Histopathological examination of the resected specimen confirmed fibromatosis. We believe this represents the third reported case of solitary colonic fibromatosis. The literature on neonatal intestinal fibromatosis is reviewed.

Is there a need for postoperative surveillance after day case groin surgery in children?

There is increasing awareness of the value of day case paediatric surgery in fulfilling the needs of the community. Is this cost effective, are there hidden complications and is there a need for routine follow-up? Seven hundred and thirty-one children attending the Red Cross War Memorial Children's Hospital day surgery unit over a 32-month period, and undergoing 912 procedures confined to the inguinoscrotal region, were enrolled in the study. Surgical procedures performed included inguinal herniotomy, orchidopexy and circumcision. Of the 731 children, 159 consecutive children had their inguinal and perineal skin flora analysed preoperatively and in 59 of these children three skin swabs were taken from the groin area: before routine skin preparation for surgery, after the skin preparation and on completion of the operation. Staphylococcus epidermidis predominated as the normal skin flora (70%), followed by Escherichia coli (19%) and Proteus mirabilis (10%), while S. aureus was only found in 2.5% of cases. The efficacy of cleaning with 4% chlorhexidine and 2% povidone-iodine in 70% alcohol is shown by virtual complete eradication of the organisms isolated from the preoperative skin cultures. In only 2 cases (3.4%) were organisms (S. aureus and S. epidermidis respectively) isolated following skin preparation. Cultures taken at the end of operative procedures grew predominantly S. epidermidis (5 cases, 8.5%). Children were discharged from the day unit once they had taken fluids and had passed urine. The wounds were also checked for any evidence of bleeding. Follow-up was done 2 weeks later by means of a visit to the day unit where the same surgeon assessed wound healing according to the Southampton Wound Assessment Scale. Ninety-four per cent of the wounds had healed by primary intention; 4.5% had minor complications and 1.5% had septic complications. Our trial confirms that wound sepsis is an infrequent but significant complication of day case groin surgery. Routine follow-up by surgical day units of minor surgical cases is not warranted and will incur unnecessary cost. Only 1.5% of postoperative cases will require further medical attention and septic lesions in the lymphatic drainage area should be regarded as risk factors.

Pediatric surgery in sub-Saharan Africa.

Pediatric surgery in sub-Saharan Africa is disadvantaged by the large number of sick children, disease patterns specific to the region, late presentation, and advanced pathology. In addition, it is practiced in an environment of limited resources and facilities and other health priorities. Obstacles to better pediatric-surgical care (PSC) include a general lack of interest in surgical conditions affecting African children, its poorly defined role, and a lack of political commitment by governments and international agencies to see surgical care of children improve. Pediatric-surgical practice in Africa must be cognizant of the factors that limit delivery of surgical services and work toward developing cost-effective strategies that benefit the largest number of children. Demonstrating that childhood surgical conditions are a significant public health-care problem is the most likely way to change health-care policy and to ensure adequate resources for PSC. Other priorities should be to define a cost-effective package of pediatric surgical services, improve PSC at the community level, and strengthen pediatric surgical-education.

Extended hepatic resection with transplantation back-up for an "unresectable" tumour.

Liver transplantation (LT) for malignancy has had disappointing long-term results due to tumour recurrence. Ex-vivo dissection and auto-transplantation have had poor results when the tumor was obstructing bile ducts. Advances in liver surgery have made extensive liver resection safer, but cases of "unresectable" tumours due to site and size still present. A 10-year-old boy was referred with jaundice due to a 6 x 8-cm central (segment 4) tumour shown on biopsy to be a fibrolamellar hepatocellular carcinoma. Ultrasound (US) and Computed Tomography also showed dilatation of intrahepatic bile ducts in both lobes. Angiography showed a large tumour mass supplied by the left branch of the hepatic artery, a low take-off of a right branch of the hepatic artery, and a very displaced but patent portal vein. The initial surgical consensus was that the tumour was unresectable. The patient was listed for LT with the plan of first attempting resection with a liver graft-in-waiting. An extended left hepatectomy was performed under total vascular exclusion with resection of the tumour, which had extended from segment 4 into surrounding segments 1, 3, 5, and 8. Intraoperative US assisted in planning the resection. The right hepatic vein, artery, and the right branch of the portal vein could be preserved and a Roux loop was anastomosed to a markedly dilated segment 6 and 7 intrahepatic duct for bile drainage. Vascular exclusion time was 30 min. The patient made a good recovery without major complications. Jaundice and bile-duct dilatation resolved. On follow up at 5 years there was no recurrence. The liver graft-in-waiting gave the surgical team confidence to proceed with an extensive resection beyond a "point of no return" and allowed good clearance of the disease and avoidance of LT with all the long-term consequences of immunosuppression. This mandates that extensive hepatic surgery in children should be carried out in centres that have a facility for LT should the need arise.

An unusual complication of retrosternal colon interposition successfully managed by median sternotomy and revision retrosternal pull-through.

An unusual complication of a retro-sternal colonic interposition is described where the redundant retro-sternal section of the graft underwent mesentericoaxial volvulus and infarction 3.5 years after the initial procedure. Access to the graft was obtained via a median sternotomy. At a second procedure the residual distal colon was used to reconstitute the interposition graft via the retro-sternal route without a repeat sternotomy with an excellent outcome. Graft redundancy is an avoidable complication of colon interposition provided certain technical steps in the operation are adhered to. Median sternotomy afforded safe access to the retro-sternal problem with good healing and long-term outcome.
