BACKGROUND: There is a significant unmet need for children's surgical care in low- and middle-income countries (LMICs). Multidisciplinary collaboration is required to advance the surgical and anesthesia care of children's surgical conditions such as congenital conditions, cancer and injuries. Nonetheless, there are limited examples of this process from LMICs. We describe the development and 3-year outcomes following a 2015 stakeholders' meeting in Uganda to catalyze multidisciplinary and multi-institutional collaboration...

BACKGROUND: Minimally invasive surgery has been considered as an alternative to open surgery by surgeons for colorectal cancer. However, the efficacy and safety profiles of robotic and conventional laparoscopic surgery for colorectal cancer remain unclear in the literature. The primary aim of this review was to determine whether robotic-assisted laparoscopic surgery (RAS) has better clinical outcomes for colorectal cancer patients than conventional laparoscopic surgery (CLS). METHODS: All randomized clinical trials (RCTs) and observational studies were systematically searched in the databases of CENTRAL, EMBASE and PubMed from their inception until January 2018...

INTRODUCTION: Colorectal cancer (CRC) is the second leading cause of cancer mortality in the USA. We aimed to determine racial and socioeconomic disparities in the surgical management and outcomes of patients with CRC in a contemporary, national cohort. METHODS: We performed a retrospective analysis of the National Inpatient Sample for the period 2009-2015. Adult patients diagnosed with CRC and who underwent colorectal resection were included. Multivariable linear and logistic regressions were used to assess the effect of race, insurance type, and household income on patient outcomes...

Hereditary breast cancers, mainly due to BRCA1 and BRCA2 mutations, account for only 5-10% of this disease. The threshold for genetic testing is a 10% likelihood of detecting a mutation, as determined by validated models such as BOADICEA and Manchester Scoring System. A 90-95% reduction in breast cancer risk can be achieved with bilateral risk-reducing mastectomy in unaffected BRCA mutation carriers. In patients with BRCA-associated breast cancer, there is a 40% risk of contralateral breast cancer and hence risk-reducing contralateral mastectomy is recommended, which can be performed simultaneously with surgery for unilateral breast cancer...

BACKGROUND: There have been recommendations for increased non-operative management (NOM) of abdominal trauma in adults. To assess the impact of this trend and changes in the epidemiology of trauma, we examined the management of serious abdominal injuries and mortality, in Victorian major trauma patients 16 years or older, between 2007 and 2016. METHODS: Using data from the population-based Victorian Trauma Registry, characteristics of patients who underwent laparotomy, embolisation, laparotomy and embolisation, or NOM, were compared with the Chi-square test...

Resection offers the only chance of long-term survival or cure for perihilar cancer, provided R0 resection is achieved with margin-negative status of the remnant liver, bile duct, proximal hepatic artery, and portal vein. End-to-end anastomosis of the portal trunk to the left portal branch is the conventional portal reconstruction in cases of right extended hepatectomy requiring resection of the portal vein bifurcation. This mandatory reconstruction may be challenging due to (1) vessel incongruence, (2) fragility of the left portal branch wall, and more importantly, and (3) the divergent orientation of the two vessels exposing to vascular twisting/kinking...

BACKGROUND: Standard therapy for loco-regionally advanced, resectable oesophageal carcinoma is trimodality therapy (TMT) consisting of neoadjuvant chemoradiotherapy and oesophagectomy. Evidence of survival advantage of TMT over organ-preserving definitive chemoradiotherapy (dCRT) is inconclusive. The aim of this study is to compare survival between TMT and dCRT. METHODS: A systematic review and meta-analyses were conducted. Randomised controlled trials and observational studies on resectable, curatively treated, oesophageal carcinoma patients above 18 years were included...

Children's surgical care is cost-effective and can avert mortality and long-term disability in children, with ramifications throughout life not only for the patient, but for the extended family and community as well. Considering the current gaps and limited capacity for children's surgery in low- and middle-income countries (LMICs), it is clear that without expanding and scaling up the infrastructure, World Health Assembly (WHA) resolution 68/15 targets and child-related targets of Sustainable Development Goals and Universal Health Care are unlikely to be met by 2030...

BACKGROUND: Readmission after surgery is an established surrogate indicator of quality of care. We aimed to compare short-term readmission rates and patient outcomes between open, video-assisted thoracoscopic (VATS), and robotic lobectomies in the Nationwide Readmissions Database (NRD). METHODS: Adults who underwent open, VATS, or robotic lobectomy for lung cancer from 2010 to 2014 were evaluated. Propensity-matched analysis was used to assess differences in readmission characteristics, GDP-adjusted cost, and mortality...

BACKGROUND: The Hirsch index, often used to assess research impact, suffers from questionable validity within the context of General Surgery, and consequently adapted bibliometrics and altmetrics have emerged, including the r-index, m-index, g-index and i10-index. This study aimed to assess the relative value of these novel bibliometrics in a single UK Deanery General Surgical Consultant cohort. METHOD: Five indices (h, r, m, g and i10) and altmetric scores (AS) were calculated for 151 general surgical consultants in a UK Deanery...
