Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.

Introduction: A nonrecurrent laryngeal nerve (NRLN) is a rare anatomical variation in which the nerve enters the larynx directly off the cervical vagus nerve. Case Report: We present 2 patients who underwent thyroid surgery for benign disease. Intraoperatively, type 2a and 1 NRLN were identified. Due to the frequent association with a vascular abnormality, an ultrasound and a computed tomography were performed which showed a right aberrant subclavian artery with a retroesophageal course and a common trunk of the common carotids in both patients. Discussion and Conclusion: The presence of an NRLN is a major risk during surgical procedures and the surgeon should be aware of the possibility of its existence. NRLN may be associated with rare vascular anomalies, such as arteria lusoria and a bicarotid trunk. This paper reveals this association in 2 patients for the first time.

Introduction: The core concepts of damage control and open abdomen in trauma surgery have been expanding for emergent general surgery. Temporary closures allow ease of access to the abdominal cavity for source control. The aim of the current study was to assess the outcomes of patients who underwent open abdomen management for acute abdominal conditions and evaluate risk factors for worse outcomes and inability of fascial closure during the initial hospitalization. Methods: We conducted a retrospective analysis of 101 patients submitted to laparostomy in a single institution from January 2009 to March 2017. The evaluated outcomes were mortality, local morbidity, and rate of primary fascial closure. Results: The most common indications for open abdomen were bowel perforation, bowel ischemia, and necrotizing pancreatitis. Global in-hospital mortality rate was 62.4%. For the 37 patients discharged from the hospital, a definitive abdominal closure was attained in 28. Multivariable logistic regression analysis revealed that people older than 60 years of age and with Acute Physiology and Chronic Health Evaluation (APACHE II) scores over 18.5 had higher in-hospital mortality rates. Definitive fascial closure was statistically associated with a lower number of re-interventions and ICU stay. Conclusions: Open abdomen management may be appropriate in these critically ill patients; however, it continues to be associated with significantly high mortality, especially in elder patients and with higher APACHE II scores. Recognition of risk factors for fascia closure failure should promote the investigation for a tailored surgical approach in these patients.

Introduction: In locally advanced rectal cancers (LARC), tumour node metastasis (TNM) staging is far from optimal. The authors aimed to investigate the value of previously described circulating biomarkers as predictors of prognosis. Methods: Retrospective analysis of 245 LARC patients diagnosed between January 2010 and December 2022, who underwent neoadjuvant chemoradiotherapy and surgery at two centres. A Cox regression and Kaplan–Meier analysis were performed. Results: Post-treatment platelet-to-lymphocyte ratio (PLR) predicted pathological complete response. The neutrophil-to-lymphocyte ratio (NLR) in two timepoints of the treatment significantly predicted overall survival, whereas the platelet-neutrophil (PN) index significantly predicted disease-free survival. In pathological stage II, the PN index predicted patients with a higher risk of disease-free survival. Conclusion: Blood parameters might allow the definition of subgroups of risk beyond TNM for the application of different therapeutic strategies.
