Global Surgery 2030: evidence and solutions for achieving health, welfare, and economic development.

Remarkable gains have been made in global health in the past 25 years, but progress has not been uniform. Mortality and morbidity from common conditions needing surgery have grown in the world’s poorest regions, both in real terms and relative to other health gains. At the same time, development of safe, essential, life-saving surgical and anesthesia care in low- and middleincome countries (LMICs) has stagnated or regressed. In the absence of surgical care, case-fatality rates are high for common, easily treatable conditions including appendicitis, hernia, fractures, obstructed labor, congenital anomalies, and breast and cervical cancer. Although the term, low- and middleincome countries (LMICs), has been used throughout the report for brevity, the Commission realizes that tremendous income diversity exists between and within this group of countries. In 2015, many LMICs are facing a multifaceted burden of infectious disease, maternal disease, neonatal disease, noncommunicable diseases, and injuries. Surgical and anesthesia care are essential for the treatment of many of these conditions and represent an integral component of a functional, responsive, and resilient health system. In view of the large projected increase in the incidence of cancer, road traffic injuries, and cardiovascular and metabolic diseases in LMICs, the need for surgical services in these regions will continue to rise substantially from now until 2030. Reduction of death and disability hinges on access to surgical and anesthesiacare,whichshouldbeavailable, affordable,timely,andsafetoensuregood coverage, uptake, and outcomes.

The global burden of injury: incidence, mortality, disability-adjusted life years and time trends from the Global Burden of Disease study 2013

Background The Global Burden of Diseases (GBD), Injuries, and Risk Factors study used the disability-adjusted life year (DALY) to quantify the burden of diseases, injuries, and risk factors. This paper provides an overview of injury estimates from the 2013 update of GBD, with detailed information on incidence, mortality, DALYs and rates of change from 1990 to 2013 for 26 causes of injury, globally, by region and by country. Methods Injury mortality was estimated using the extensive GBD mortality database, corrections for ill-defined cause of death and the cause of death ensemble modelling tool. Morbidity estimation was based on inpatient and outpatient data sets, 26 cause-of-injury and 47 nature-of-injury categories, and seven follow-up studies with patient-reported long-term outcome measures. Results In 2013, 973 million (uncertainty interval (UI) 942 to 993) people sustained injuries that warranted some type of healthcare and 4.8 million (UI 4.5 to 5.1) people died from injuries. Between 1990 and 2013 the global age-standardised injury DALY rate decreased by 31% (UI 26% to 35%). The rate of decline in DALY rates was significant for 22 cause-of-injury categories, including all the major injuries. Conclusions Injuries continue to be an important cause of morbidity and mortality in the developed and developing world. The decline in rates for almost all injuries is so prominent that it warrants a general statement that the world is becoming a safer place to live in. However, the patterns vary widely by cause, age, sex, region and time and there are still large improvements that need to be made.

History and development of trauma registry: lessons from developed to developing countries

BackgroundA trauma registry is an integral component of modern comprehensive trauma care systems. Trauma registries have not been established in most developing countries, and where they exist are often rudimentary and incomplete. This review describes the role of trauma registries in the care of the injured, and discusses how lessons from developed countries can be applied toward their design and implementation in developing countries.MethodsA detailed review of English-language articles on trauma registry was performed using MEDLINE and CINAHL. In addition, relevant articles from non-indexed journals were identified with Google Scholar.ResultsThe history and development of trauma registries and their role in modern trauma care are discussed. Drawing from past and current experience, guidelines for the design and implementation of trauma registries are given, with emphasis on technical and logistic factors peculiar to developing countries.ConclusionImprovement in trauma care depends on the establishment of functioning trauma care systems, of which a trauma registry is a crucial component. Hospitals and governments in developing countries should be encouraged to establish trauma registries using proven cost-effective strategies.

Challenges of training and delivery of pediatric surgical services in Africa

BACKGROUND The practice of pediatric surgery in Africa presents multiple challenges. This report presents an overview of problems encountered in the training of pediatric surgeons as well as the delivery of pediatric surgical services in Africa. METHODS A returned structured self-administered questionnaire sent to pediatric surgeons practicing in Africa was reviewed and analyzed using SPSS version 11.5 (SPSS, Chicago, IL). RESULTS Forty-nine (57%) of 86 questionnaires were returned from 8 countries. Great variability in the requirements and training of pediatric surgeons, even within the same country, was found. Many surgical colleges are responsible for standardization and board certification of pediatric surgeons across Africa. There were 6 (12%) centers that train middle level manpower. Twenty-six (53%) participants have 1 to 2 trainees, whereas 22 (45%) have irregular or no trainee. A pediatric surgical trainee needs 2 to 4 (median, 2) years of training in general surgery to be accepted for training in pediatric surgery, and it takes a trainee between 2 to 4 (median, 3) years to complete training as a pediatric surgeon in the countries surveyed. The number of pediatric surgeons per million populations is lowest in Malawi (0.06) and highest in Egypt (1.5). Problems facing adequate delivery of pediatric surgical services enumerated by participants included poor facilities, lack of support laboratory facilities, shortage of manpower, late presentation, and poverty. CONCLUSION The training of pediatric surgical manpower in some African countries revealed great variability in training with multiple challenges. Delivery of pediatric surgical services in Africa presents problems like severe manpower shortage, high pediatric surgeon workload, and poor facilities. Standardization of pediatric surgery training across the continent is advocated, and the problems of delivery of pediatric surgical services need to be addressed urgently, not only by health care planners in Africa but by the international community and donor agencies, if the African child is to have access to essential pediatric surgical services like his or her counterpart in other developed parts of the world.

Emergency neonatal surgery in a developing country

Abstract With better understanding of neonatal physiology and improvements in diagnostic facilities and neonatal intensive care units (NICU), the outcome of neonatal surgery has improved in developed countries. In developing countries, however, neonatal surgery is problematic, particularly in the emergency setting, but there are few reports from these countries. A retrospective analysis of 154 neonates who had emergency surgery over a 10-year period at the Ahmadu Bello University Teaching Hospital, Zaria, Nigeria, was undertaken. Emergency surgery represented 40% of surgical procedures in neonates in the hospital. The majority of the patients (94.8%) were delivered at home or in rural health centers. The median weight was 2.7 kg (range 2.0–3.7 kg). In 89 cases (58%) the indications for surgery were intestinal obstruction, anorectal malformations in 60(67%) and in 33(21%) complicated exomphalos or gastroschisis. Nine patients (6%) required surgery for ruptured neural-tube defects. A colostomy was the commonest procedure (51, 33%), 27(53%) of which were performed using a local anesthetic without adverse effects. Thirty-three abdominal-wall defects were closed by various methods (fascial closure 23, skin closure 6, improvised silo 4). Overall, 37 (24%) procedures were performed using local anesthesia. Fifty-nine patients (38%) developed postoperative complications (infections 33, respiratory insufficiency 16, colostomy complications 8, anastomotic leak 2). The mortality was 30.5%, 66% due to overwhelming infection, 28% to respiratory insufficiency, and 4.3% to multiple anomalies. Other factors considered to have contributed to morbidity and mortality were late referral and presentation and a lack of NICUs. Thus, emergency neonatal surgery is attended by high morbidity and mortality in our environment at the present time. Early referral and presentation and provision of NICUs should improve the outcome.

Typhoid ileal perforation in children: a scourge in developing countries.

Over a 10-year period, 64 children aged < or = 12 years were treated for typhoid perforation, accounting for 56% of all cases of typhoid perforation at our institution. The perforation rates in the age groups < 1, 1-4, 5-9 and 10-12 years were 4%, 1.7%, 12.4% and 29.3%, respectively, with an overall perforation rate of 10.3%. The main features were fever (93.4%) and abdominal pain and tenderness (93.4%). Thirteen children (20.3%) had associated haemorrhage, presenting as haematochezia. The incidence of perforations was 52% during the rainy season and 48% during the dry season, but the disease occurred throughout the year with a peak in October, the beginning of the dry season, which was also the time of peak occurrence of typhoid without perforation. An average of 14 h (range 5-30) was required for resuscitation. Ketamine was used for anaesthesia in most cases. Treatment was by segmental resection (67%), wedge excision (17%) and simple closure (6%). Morbidity was high (53%), and wound infection (53%) and chest infection (30%) were the most common complications. There were 25 deaths (39%), most the result of overwhelming sepsis. Late presentation at > 7 days was associated with high mortality (p < 0.05). Typhoid perforation continues to be a scourge in children in developing countries and, in addition to preventive measures such as improved sanitation and the provision of safe water supplies, public enlightenment is necessary to ensure early presentation and improved survival.

Posterior urethral valve

BackgroundPosterior urethral valve (PUV) is a significant cause of morbidity, mortality and ongoing renal damage in children. It accounts for end-stage renal disease in a proportion of children. This article aims at highlighting the current trend in the management of boys with posterior urethral valve.Data sourcesPubMed/Medline and bibliographic search for posterior urethral valve was done. Relevant literatures on presentation, pathology, evaluation, management and outcomes of PUV were reviewed.ResultsPUV which is increasingly diagnosed prenatally presents a spectrum of severity. The varied severity and degree of obstruction caused by this abnormality depend on the configuration of the obstructive membrane within the urethra. The decision to intervene prenatally is dependent on gestational age, amniotic volume, and renal function of fetal urine aspiration. Identification of the patients who may benefit from early intervention remains inconclusive. Endoscopic ablation of the valve is the gold standard of treatment but use of Mohan’s valvotome and other modalities are invaluable in developing countries where endoscopic facilities are limited. Proximal urinary diversion may result in poor bladder compliance and should be reserved for patients with persisting or increasing upper urinary tract dilatation, increasing serum creatinine or inappropriate instruments. The behavior of the bladder and its subsequent management after valve ablation may influence the long-term renal outcome in PUV patients.ConclusionsThe care of children with PUV continues to improve as a result of earlier diagnosis by ultrasound, developments in surgical technique and meticulous attention to neonatal care. The ultimate goal of management should be to maximize renal function, maintain normal bladder function, minimize morbidity and prevent iatrogenic problems.

Surgical site infection in children: prospective analysis of the burden and risk factors in a sub-Saharan African setting.

BACKGROUND Surgical site infections (SSI) add substantially to the morbidity of surgical patients. Our hypothesis was that the SSI rate is high in our setting, but there were no data regarding the prevalence and risk factors. METHODS Three hundred twenty-two children who had surgery (elective 144, emergency 178) between January, 2001 and September, 2005 were studied prospectively. All patients with clean-contaminated, contaminated, and dirty incisions received prophylactic antibiotics. Data were collected using a tool that captured demographics, diagnosis, co-morbid conditions, type of surgical incision, nature of surgery, type of anesthesia, use of perioperative antibiotics, and duration of surgery. Information also was collected postoperatively on the development of SSI, type of infection, associated signs, the day the infection was identified, the findings in cultures of swabs from infected incisions, duration of hospital stay, and outcome. The chi-square test for categorical variables was used to test for significance of association. The p value for significance was set at 0.05. RESULTS Seventy-six patients (23.6%) consisting of 40 boys and 36 girls developed SSI. The median age was nine months (range, 2 days-12 years) for those who developed SSI and 15 months (range, 1 day-13 years) for those who did not. The SSI rate was 14.3% in clean incisions, 19.3% in clean-contaminated incisions, 27.3% in contaminated incisions, and 60% in dirty incisions (p < 0.05). The infection rate was 25.8% in emergency procedures and 20.8% in elective procedures (p > 0.05). The infection rate was 31% in operations lasting >or= 2 h and 17.3% in operations lasting < 2 h (p < 0.05). Infection was detected before the eighth postoperative day in 56 of the patients (74.6%) with SSI, and bacteria were cultured from the incision in 32 patients (42.7%). The average length of stay was 26.1 days (range, 8-127 days) in patients with SSI and 18.0 days (range, 1-99 days) in those without SSI (p < 0.05). The mortality rate of patients with SSI was 10.5%, with six of the eight deaths related directly to the SSI, compared with a mortality rate of 4.1% in patients without SSI (p < 0.05). CONCLUSION The burden of SSI in this setting is high. The degree of incisional contamination and a long duration of surgery (>or= 2 h) are important risk factors.

Global Surgery 2030: evidence and solutions for achieving health, welfare, and economic development

Remarkable gains have been made in global health in the past 25 years, but progress has not been uniform. Mortality and morbidity from common conditions needing surgery have grown in the world’s poorest regions, both in real terms and relative to other health gains. At the same time, development of safe, essential, life-saving surgical and anaesthesia care in low-income and middle-income countries (LMICs) has stagnated or regressed. In the absence of surgical care, case-fatality rates are high for common, easily treatable conditions including appendicitis, hernia, fractures, obstructed labour, congenital anomalies, and breast and cervical cancer. In 2015, many LMICs are facing a multifaceted burden of infectious disease, maternal disease, neonatal disease, non-communicable diseases, and injuries. Surgical and anaesthesia care are essential for the treatment of many of these conditions and represent an integral component of a functional, responsive, and resilient health system. In view of the large projected increase in the incidence of cancer, road traffic injuries, and cardiovascular and metabolic diseases in LMICs, the need for surgical services in these regions will continue to rise substantially from now until 2030. Reduction of death and disability hinges on access to surgical and anaesthesia care, which should be available, affordable, timely, and safe to ensure good coverage, uptake, and outcomes. Despite growing need, the development and delivery of surgical and anaesthesia care in LMICs has been nearly absent from the global health discourse. Little has been written about the human and economic effect of surgical conditions, the state of surgical care, or the potential strategies for scale-up of surgical services in LMICs. To begin to address these crucial gaps in knowledge, policy, and action, the Lancet Commission on Global Surgery was launched in January, 2014. The Commission brought together an international, multi- disciplinary team of 25 commissioners, supported by advisors and collaborators in more than 110 countries and six continents. We formed four working groups that focused on thedomains of health-care delivery and management; work-force, training, and education; economics and finance; and information management. Our Commission has five key messages, a set of indicators and recommendations to improve access to safe, affordable surgical and anaesthesia care in LMICs, and a template for a national surgical plan.
