A series of recommendations regarding hospital perioperative preparation for the COVID-19 pandemic were compiled to inform surgeons worldwide on how to provide emergency surgery and trauma care during enduring times.The recommendations are divided into eight domains: (1) General recommendation for surgical services; (2) Emergency Surgery for critically ill COVID-19 positive or suspected patients -Preoperative planning and case selection; (3) Operating Room setup; (4) patient transport to the OR; (5) Surgical staff preparation; (6) Anesthesia considerations; (7) Surgical approach; and (8) Case Completion.The European Society of Emergency Surgery board endorsed these recommendations.

Colorectal cancer commonly presents first as an emergency and is likely to be complicated by bowel obstruction/perforation requiring more difficult procedures, with poorer outcomes. Analysis of all of the procedures performed on patients diagnosed in Wexford General Hospital, Ireland, during the period 2000 to 2006 was carried out to validate this hypothesis in our western European population. Retrospective analysis of a prospectively maintained database of patient demographics, diagnosis, procedures, and mode of presentation (elective, emergency) was undertaken. A total of 356 patients with colorectal cancer underwent 498 procedures during the years 2000 to 2006. Eighty-four emergency endoscopies and 100 emergency bowel resections were performed. Obstructive lesions were more likely to require emergency resection (P < 0.001). Median survival time for patients treated electively was 82 months vs. 59 months for patients treated on an emergency basis. Of all colonic resections, 34 percent were carried out as emergencies and were significantly more likely to be complicated by obstruction or perforation (P < 0.001). Emergency resections were associated with a significantly poorer perioperative mortality and five-year survival rate (P < 0.001). Forty-one percent of colorectal cancers diagnosed at endoscopy were first seen emergently. These data raise concerns regarding public awareness of colorectal cancer and resource allocation and reemphasize the need for a national colorectal screening program.

BACKGROUND: The management of penetrating colon injuries in civilians has evolved over the last four decades. The objectives of this meta-analysis are to evaluate the current treatment regimens available for penetrating colon injuries and assess the role of anastomosis in damage control surgery to develop a practice management guideline for surgeons. METHODS: Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, a subcommittee of the Practice Management Guidelines section of EAST conducted a systematic review using MEDLINE and EMBASE articles from 1980 through 2017. We developed three relevant problem, intervention, comparison, and outcome (PICO) questions regarding penetrating colon injuries. Outcomes of interest included mortality and infectious abdominal complications. RESULTS: Thirty-seven studies were identified for analysis, of which 16 met criteria for quantitative meta-analysis and included 705 patients considered low-risk in six prospective randomized studies. Seven hundred thirty-eight patients in 10 studies undergoing damage control laparotomy and repair or resection and anastomosis (R&A) were included in a separate meta-analysis. Meta-analysis of high-risk patients undergoing repair or R&A was not feasible due to inadequate data. CONCLUSIONS: In adult civilian patients sustaining penetrating colon injury without signs of shock, significant hemorrhage, severe contamination, or delay to surgical intervention we recommend that colon repair or R&A be performed rather than routine colostomy. In adult high-risk civilian trauma patients sustaining penetrating colon injury, we conditionally recommend that colon repair or R&A be performed rather than routine colostomy. In adult civilian trauma patients sustaining penetrating colon injury who had damage control laparotomy, we conditionally recommend that routine colostomy not be performed; instead, definitive repair or delayed R&A or anastomosis at initial operation should be performed rather than routine colostomy. LEVEL OF EVIDENCE: Systematic review/meta-analysis, level III.

Postoperative death within 1 year following hip fracture surgery is reported to be up to 27%. In the current study, we benchmarked the predictive precision and accuracy of the algorithms support vector machine (SVM), naïve Bayes classifier (NB), and random forest classifier (RF) against logistic regression (LR) in predicting 1-year postoperative mortality in hip fracture patients as well as assessed the relative importance of the variables included in the LR model. All adult patients who underwent primary emergency hip fracture surgery in Sweden, between 1 January 2008 and 31 December 2017 were included in the study. Patients with pathological fractures and non-operatively managed hip fractures, as well as those who died within 30 days after surgery, were excluded from the analysis. A LR model with an elastic net regularization were fitted and compared to NB, SVM, and RF. The relative importance of the variables in the LR model was then evaluated using the permutation importance. The LR model including all the variables demonstrated an acceptable predictive ability on both the training and test datasets for predicting one-year postoperative mortality (Area under the curve (AUC) = 0.74 and 0.74 respectively). NB, SVM, and RF tended to over-predict the mortality, particularly NB and SVM algorithms. In contrast, LR only over-predicted mortality when the predicted probability of mortality was larger than 0.7. The LR algorithm outperformed the other three algorithms in predicting 1-year postoperative mortality in hip fracture patients. The most important predictors of 1-year mortality were the presence of a metastatic carcinoma, American Society of Anesthesiologists(ASA) classification, sex, Charlson Comorbidity Index (CCI) ≤ 4, age, dementia, congestive heart failure, hypertension, surgery using pins/screws, and chronic kidney disease.
