Background Identification of patients at high risk of surgical-site infections may allow surgeons to minimize associated morbidity. However, there are significant concerns regarding the methodological quality and transportability of models previously developed. The aim of this study was to develop a novel score to predict 30-day surgical-site infec...

Background Surgical site infection (SSI) is a major burden on patients and health systems. This study assessed the cost-effectiveness of routine change of sterile gloves and instruments before abdominal wall closure to prevent SSI.

BACKGROUND: The CovidSurg-Cancer Consortium aimed to explore the impact of COVID-19 in surgical patients and services for solid cancers at the start of the pandemic. The CovidSurg-Gynecologic Oncology Cancer subgroup was particularly concerned about the magnitude of adverse outcomes caused by the disrupted surgical gynecologic cancer care during th...

Background: This study assessed the potential cost-effectiveness of high (80e100%) vs low (21e35%) fraction of inspired oxygen (FiO 2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa. Methods: Decision-analytic models were constructed using best available evidence sourced from unbundled data...

Academic global surgery is a rapidly growing field that aims to improve access to safe surgical care worldwide. However, no universally accepted competencies exist to inform this developing field. A consensus-based approach, with input from a diverse group of experts, is needed to identify essential competencies that will lead to standardization in...

Background: Surgical site infection (SSI) is the most common complication of abdominal surgery, with substantial costs to patients and health systems. Heterogeneity in costing methods in existing SSI studies makes multi-country comparison challenging. The objective of the study was to assess the costs of SSI across middle-income countries. Method...

Introduction: Surgically correctable congenital anomalies are responsible for a significant burden of morbidity and mortality in children from low-and lower-middle-income countries (LMICs). Early identification through fetal and neonatal screening is critical to reducing death and disability. This study aims to identify feasible screening methods...

Biliary atresia (BA) is a rare disease characterised by biliary obstruction of unknown origin that presents in the neonatal period. It is classified into syndromic with various congenital anomalies and non-syndromic (isolated anomaly). We present a case of syndromic BA associated with polysplenia and intestinal malrotation, discovered incidentally...

Introduction: The Surgeons OverSeas Assessment of Surgical Needs (SOSAS) survey tool is used to determine the unmet surgical needs in the community and has been validated in several countries. A major weakness is the absence of an objective assessment to verify patient-reported surgically treatable conditions. The goal of this study was to determi...

Background The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning.

Cysts of the prepuce are rare, and documented reports from the English literature are mostly from Asia. Presentations in children are worrisome to the parents. We report a case of a preputial cyst occurring in a neonate who was brought to our facility due to parental anxiety. After a thorough clinical evaluation, a freehand circumcision technique w...

In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 10...

Background: Male circumcision is the most common surgical procedure worldwide and is often carried out for religious, cultural, medical and public health reasons. It is commonly performed during the neonatal period. Many studies have now shown that pain is a common intra- and post-operative complication. To ensure proper analgesia during the proce...

Background : The aim of this study is to investigate the impact that COVID-19 had on the pattern and trend of surgical volumes, urgency and reason for surgery during the first 6 months of the pandemic in sub-Saharan Africa.

Objectives: To reduce preventable deaths of newborns and children, the United Nations set a target rate per 1000 live births of 12 for neonatal mortality (NMR) and 25 for under-5 mortality (U5MR). The purpose of this paper is to define the minimum surgical workforce needed to meet these targets and evaluate the relative impact of increasing surgeo...

Objectives Paediatric cancer is a leading cause of death for children. Children in low-income and middle-income countries (LMICs) were four times more likely to die than children in high-income countries (HICs). This study aimed to test the hypothesis that the COVID-19 pandemic had affected the delivery of healthcare services worldwide, and exacerb...

Background: Over the last two decades, there has been significant improvement in the outcomes of children with Wilms' tumour (WT) in high income countries (HICs) with approximately 85% survival rate globally. This is partly attributable to a multi-disciplinary team approach to care and the evolution of more robust treatment measures. A previous re...

Background: The impact of the corona virus disease 2019 (COVID-19) pandemic on global health, has reached far beyond that caused by the disease itself. With ongoing mutations and the emergence of new strains of the virus alongside repeated waves of the pandemic, the full impact of the pandemic is still evolving and remains difficult to predict or...

Background In Nigeria, the prescription of surgical antibiotic prophylaxis for prevention of surgical site infection tends to be driven by local policy rather than by published guidelines (e.g. WHO and Sanford).

Background: Despite a decreasing global neonatal mortality, the rate in sub-Saharan Africa is still high. The contribution and the burden of surgical illness to this high mortality rate have not been fully ascertained. This study is performed to determine the overall and disease-specific mortality and morbidity rates following neonatal surgeries; a...

Background Existing emergency general surgery (EGS) guidelines rarely include evidence from low- and middle-income countries (LMICs) and may lack relevance to low-resource settings.

Background: The ultimate goal of learning is to modify the behavior of which enhanced performance is a critical aspect.

Background This study aimed to determine the impact of pulmonary complications on death after surgery both before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Methods This was a patient-level, comparative analysis of two, international prospective cohort studies: one before the pandemic (January–October 201...

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients.Since surgical patients are already at higher risk of venous thromboembolism than general populations, thisstudy aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk ofvenous thromboembolism. We...

There is little evidence around the potentially protective role of previous Bacillus Calmette-Guerin (BCG) vaccination on postoperative mortality in patients with perioperative SARS-CoV-2 vaccination. Prior BCG vaccination did not protect SARS-CoV-2 infected patients against postoperative pulmonary complications and 30-day mortality.

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which pati...

Background Surgical site infection (SSI) is the most common postoperative complication worldwide. WHO guidelines to prevent SSI recommend alcoholic chlorhexidine skin preparation and fascial closure using triclosan-coated sutures, but called for assessment of both interventions in low-resource settings. This study aimed to test both interventions i...

Background: Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction.
