Cervical lymph node biopsy - watch the nerves!

Experience with the delayed diagnosis and severe consequences of accessory nerve injury following cervical gland lymph node biopsy prompted us to survey the practice of South African paediatric surgeons and to ascertain the incidence of accessory nerve injury. Cervical lymph gland biopsies are often performed for diagnostic and therapeutic purposes and although spinal accessory nerve (SAN) injury seldom occurs, it remains a significant injury. The operation is relatively minor and cervical glands are commonly biopsied/removed in South Africa by junior doctors, registrars and general practitioners. The operation is often performed as a day case under suboptimal circumstances, despite the fact that it is common knowledge that posterior triangle nodular biopsy carries the risk of iatrogenic damage to the accessory nerve

Button batteries in the oesophagus: A surgical emergency

We describe two cases of missed battery ingestion that led to extensive morbidity, requiring surgical management that would not have been necessary had the batteries been removed timeously

Prevention of ingestion injuries in children

Accidental caustic and foreign body ingestion by young children lead to a high number of emergency department visits, especially in lower- and middle-income countries. Some of these cause minimal tissue injury or pass spontaneously and uneventfully through the gastrointestinal tract; others may cause major morbidity, or rarely mortality. Increased primary prevention of ingestion through community awareness and vigilant childcare in addition to legislative steps to ensure a safe environment for these vulnerable members of society are needed. Secondary prevention of long-term sequelae through timely and appropriate assessment and referral for endoscopy, laparotomy or other treatments can limit morbidity where primary prevention fails. Basic guidelines for management principles are suggested. Social lobby is required to further reform commercial risks to children in addition to creating caregiver awareness of common environmental hazards, particularly in developing countries such as South Africa

Meningococcal septicaemia complications involving skin and underlying deeper tissues - management considerations and outcome

Objective: To describe surgical experience with purpura fulminans related to meningococcaemia in a single institution, and to suggest a management protocol. Methods: A retrospective review was done of patients admitted to the intensive care unit at Red Cross War Memorial Children's Hospital in Cape Town with the clinical diagnosis of purpura fulminans. Results: During a 28-year period (1977 - 2005) 112 children (average age 3.4 years) were treated for meningococcaemia with purpura fulminans. Overall mortality was 10.7%. Local treatment consisted of measures to improve circulation, infection control and healing of necrotic tissue. Demarcation of necrotic areas was evident at 5.5 days and the average area of skin necrosis was 14% total body surface area (range 2 - 85%). The lower limbs were predominantly affected. Purpura fulminans resolved in 35 children (31.2%) without skin necrosis. Skin grafting was required in 77 children (68.8%). Factors associated with a poor outcome for peripheral extremity salvage were progressive irreversible skin changes, early disappearance of distal pulses, tense cold swollen extremities and intense pain on passive movement of the affected extremity. Amputations were performed proximal to the area of necrosis, on average 27 days after injury. Conclusions: Meningococcaemia is a disease with potentially devastating consequences. Early surgical consultation is essential. Skin- and soft-tissue-releasing incisions should be considered early to reduce the incidence of extremity necrosis. Small necrotic areas usually separate spontaneously with secondary healing or can be excised and sutured. Larger necrotic areas should be excised only after demarcation has been established, and can be covered with delayed skin grafting. Amputation should be conservative but may require revision

Situs inversus abdominalis and duodenal atresia. A case report and review of the literature

Fewer than 20 patients born with situs inversus and duodenal atresia have been reported in the literature. We present a patient with this condition. A newborn baby presented shortly after birth with persistent bilious vomiting. An abdominal radiograph showed a right-sided stomach bubble and a second bubble on the left - typical of duodenal atresia but with mirror image configuration. Laparotomy confirmed the diagnosis of situs inversus abdominalis, which was also demonstrated by contrast studies and ultrasound. Duodenoduodenostomy was performed and the patient discharged on day 8 postoperatively. Situs inversus is associated with other congenital malformations including splenic malformations, left-sided liver and cardiac abnormalities; it is rarely associated with duodenal atresia. Duodenal obstruction in the presence of situs inversus has been described, including obstruction due to a web, stenosis, pre-duodenal portal vein and complete atresia. The patient presented in this paper had a duodenal web in the second part of the duodenum. Before undertaking surgery it is important to establish the presence of associated gastrointestinal and cardiac abnormalities

A practical approach to anaesthesia for paediatric liver transplantation

Anaesthesia for paediatric liver transplantation requires meticulous attention to detail, an understanding of the disease process leading up to the need for transplantation, and an awareness of the haematological, biochemical, and multi-organ consequences of this operation. In the past 20 years, significant advances in surgical techniques, organ procurement and preservation, immunosuppression, anaesthetic management and monitoring, and postoperative care in the intensive care unit have contributed to improved outcomes of both the graft and the patient. In more recent years, the use of reduced size and living related organs has increased the donor pool for infants and children. Paediatric liver transplantation in South Africa, up until the present time, has been centered at the Red Cross Children's Hospital in Cape Town, and survival rates here are comparable with international figures. This paper highlights the preoperative problems which face the anaesthetist, emphasises the importance of good planning and preparation for the intraoperative procedure, simplifies the surgical technique of the operation, and stresses the value of a multidisciplinary approach to the child requiring liver transplantation.Southern African Journal of Anaesthesia and Analgesia Vol. 12(1) 2006: 11-1

Salvageability of renal function following renal revascularisation in children with Takayasu’s arteritis-induced renal artery stenosis

Background. Renal artery revascularisation procedures are usually carried out on children with renal artery stenosis from varied causes, including Takayasu’s   arteritis. Reports on the outcome of such procedures in children usually refer to the improvement in blood pressure, with only minimal mention of effects on renal  function.Objective. Salvageability renal function in children who underw ent renal  revascularisation for Takayasu’s arteritis-induced renal artery stenosis (TARAS) was the focus of this study.Methods. We undertook a retrospective analysis of children aged ≤16 years with angiographically confirmed TARAS who underwent renal artery revascularisation procedures between 1990 and 2010. Outcomes of renal function were studied over a period of 2 years and were defined as: (i) improvement: >20% increase in estimated glomerular filtration rate (e-GFR) from presurgery value; (ii) stabilisation: e-GFR within 20% of presurgery value; and (iii) failure: >20% deterioration in e-GFR from presurgery value. The GFR was estimated using the Schwartz formula.Results. Twenty children (9 males and 11 females, age range 2 - 14 years) had 27 renal artery revascularisation procedures. Thirteen of the patients (65.0%) had bilateral renal artery stenosis. The baseline mean e-GFR was 88.6 (standard deviation (SD) 25.4) mL/min/1.73 m2 and the mean duration of follow-up was 28.80 (SD 25.62) months. All the patients had stable or improved renal function until the 2-year follow-up, when the proportion decreased to 92.3% (12/13), as failure was recorded in one child. Bilateral revascularisation was found to be significantly associated with improvement in renal function in the early postoperative period  (p=0.04).Conclusion. Renal artery revascularisation procedures are successful in salvaging renal function in children with TARA
