Background and Aims: The management of duodenal trauma remains controversial. This retrospective audit of a prospectively maintained database was intended to clarify the operative management of duodenal injury at our institution and to assess the risk factors for leak following primary duodenal repair. Materials and Methods: This was a retrospective study undertaken at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa. Operative techniques used for duodenal repair were recorded. Our primary outcome was duodenal leak in the postoperative period. Patients from January 2012 to December 2016 were included. All duodenal injuries were graded according to the American Association for the Surgery of Trauma (AAST) grading. Only patients who had a primary repair were included in the final analysis. Results: During the five-year data collection period, a total of 562 patients underwent a trauma laparotomy; of which 94 patients sustained a duodenal injury. A primary pyloric exclusion and gastro-jejunostomy (PEG) was performed in three patients. These three were then excluded from further analysis. Of the 91 primary duodenal repairs, seven (8%) subsequently leaked. These were managed by PEG in three and by secondary repair and para-duodenal drainage in four. The two physiological parameters most associated with subsequent leak were lactate and pH level. There was a significantly higher mortality rate for those who leaked vs those who did not leak. Chi-squared test revealed a significant difference in the leak rate between AAST I (0%), AAST-II (1.6%) and AAST-3 (66.7%) grade injuries (p <0.01). Conclusion: The trend towards primary repair of duodenal injuries appears to be justified. However duodenal leak remains a significant risk in certain high risk patients and strategies to manage injuries in this subset requires further work.

Introduction This study is a five-year follow-up of previously published review of the trauma workload at our institution. It aims to provide evidence about the quality of trauma care delivered by a major academic trauma service in South Africa to provide a temporal analysis of trauma trends in the city of Pietermaritzburg. Materials and methods All trauma patients admitted by the Pietermaritzburg Metropolitan Trauma Service (PMTS) for the period December 2012-April 2018 were retrieved from the Hybrid Electronic Medical Registry (HEMR) for analysis.Results Over the five-year period, a total of 8722 trauma patients were admitted to Grey's Hospital. There were 7242 (83.0%) males. The average age was 29.66 years. A total of 1719 (19.7%) patients less than 19 years of age, 377 (4.3%) older than 60 years of age and 1480 (17.0%) female patients were admitted following trauma. Table 3 breaks down the mechanism of trauma. A total of 5027 patients sustained blunt trauma (57.6%), and 3334 (38.5%) sustained penetrating trauma. A total of 4808 patients sustained intentional trauma implying that 55.1% of all trauma was secondary to grievous bodily harm or assault either in the form of a stab wound or GSW or of an assault. There was a total of 2232 road traffic-related incidents, of which 37.9% (845) were pedestrian victims. The mortality rate for all trauma admissions was 4.5% (396). Of these 396 deaths, 64 (16.2%) were classified at the morbidity and mortality conference as being avoidable.Conclusions The HEMR has allowed us to track the burden of trauma presenting to our institution over a five-year period. This confirms previous studies over shorter time periods from our institution. The pattern of trauma has remained consistent, and the previously described high levels show no sign of decreasing. Interventions to try and reduce this burden are urgently required.

Introduction This audit focused on patients who sustained enteric injury following blunt abdominal trauma. Methods Our prospectively maintained electronic registry was interrogated retrospectively, and all patients who had sustained blunt abdominal trauma between December 2011 and January 2016 were identified. Results Overall, 2,045 patients had sustained blunt abdominal trauma during the period under review. Seventy per cent were male. The median age was 28 years. Sixty patients (2.9%) sustained a small bowel injury (SBI). Thirty-five of these were peritonitic on presentation. All patients with a SBI had a chest x-ray and free air was present in seven. In 18 patients with a SBI, computed tomography (CT) was performed, which revealed isolated free fluid in 12 and free intraperitoneal air in 5. In five cases, the CT was normal. A total of 32 patients (1.5%) sustained blunt duodenal trauma (BDT). All patients with BDT had a chest x-ray on presentation. Free intraperitoneal air was not present in any. CT was performed on 17 patients with BDT. This revealed isolated free fluid or retroperitoneal air in 12. The median delay between injury and presentation for these enteric injures was 15.5 hours (interquartile range [IQR]: 8-25 hours) while between presentation at hospital and operation, the median delay was 6 hours (IQR: 3-13 hours). Conclusions Blunt trauma related enteric hollow visceral injury remains associated with delayed diagnosis and significant morbidity. It can be caused by a disparate array of mechanisms and is difficult to diagnose even with modern imaging strategies.

SNOM is applicable to a well-defined subset of patients with isolated penetrating cervical venous trauma to the IJV and SCV identified on CTA.

Background qSOFA has been proposed as a prognostic tool in patients with sepsis. This study set out to assess the sensitivity of several scores, namely: the pre‐ICU qSOFA, the qSOFA with lactate (qSOFA L), SIRS score, qSOFA + SIRS score (qSIRS) and qSIRS with lactate (qSIRS L) in predicting in‐hospital mortality in patients with surgical sepsis as well as the sensitivity of these scores in predicting high‐grade sepsis. The secondary aim was to determine which of these scores is best suited to predict high‐grade surgical sepsis. Methods This was a retrospective cohort study that was conducted between December 2012 and August 2017 in a public metropolitan surgical service. Data from patients aged > 13 years, who were admitted to the hospital and who had an emergency surgical procedure for source control were retrieved from a prospectively maintained hybrid electronic database. The qSOFA, qSOFA plus lactate (qSOFA L), SIRS and qSOFA + SIRS (qSIRS), as well as the qSIRS plus lactate (qSIRS L), were calculated for each patient. A lactate level that was greater than 2mmol/L was deemed to be a positive finding. Any score ≥2 was deemed to be a positive score. The outcome measure was in‐hospital mortality. The prognostic value of qSOFA, qSOFA L, SIRS, qSIRS and qSIRS L was studied. Receiver operating characteristic analyses were performed to determine the area under the curve (AUC), sensitivity, specificity and positive and negative likelihood ratios for positive qSOFA, qSOFA L, SIRS, qSIRS, and qSIRS L. Contingency tables were used to calculate the sensitivity, specificity, PPV and NPV for predicting severe or high‐grade surgical sepsis. Results There were a total number of 1884 patients in the sample group of whom 855 were female (45.4%). The median patient age was 36 years (IQR 23–56). A total of 1489 patients (79%) were deemed to have high‐grade sepsis based on an advanced EGS AAST grading, whilst 395 patients (21%) had low‐grade sepsis. A total of 71 patients died (3.8%). Of these patients who died, 67 (94.4%) had high‐grade sepsis and 4 (5.6%) had low‐grade sepsis. The mortality rate in the high‐grade sepsis group was 4.5%, whilst the mortality rate in the low‐grade sepsis group was 1%. The scores with the greatest accuracy in predicting mortality were qSIRS (AUROC 0.731, 95% CI 0.68–0.78), followed by SIRS (AUROC 0.70, 95% CI 0.65–0.75). The qSOFA and qSOFA L were the least accurate in predicting mortality (AUROC 0.684, 95% CI 0.63–0.74 for both). The addition of lactate had no significant effect on the accuracy of the five scores in predicting mortality. Patients with a qSOFA ≥ 2 have an increased risk of dying (OR 5.8), as do patients with a SIRS score ≥2 (OR 2.7). qSIRS L had the highest sensitivity (69%) in predicting the presence of high‐grade surgical sepsis, followed by qSIRS (65.5% sensitivity). qSOFA showed a very low sensitivity of only 4.5% and a high specificity of 99.2%. The addition of lactate to the score marginally improved the sensitivity. Lactate of 2mmol/L or more was also an independent...
