RESUMO

Minimally invasive surgery is a useful alternative to open repair for patients with nonruptured abdominal aortic aneurysms (AAA). We aim to compare the clinical outcomes for three different minimally invasive techniques: hand-assisted laparoscopic surgery (HALS), total laparoscopic surgery (TLS), and endovascular aneurysm repair (EVAR). The electronic databases MEDLINE, Embase, Web of Science, Google Scholar, and the Cochrane Library were searched between January and March 2023. Cohort studies and randomized controlled trials (RCTs) comparing two minimally invasive techniques were eligible for inclusion. Primary outcomes were mortality (in-hospital, 30-day, or 1-year) and reintervention rates (30-day or 1-year). Length of surgery, blood loss, transfusion volume, conversion to open surgery, major complication rates, length of hospital stay, and length of intensive care unit (ICU) stay were also evaluated. Eight cohort studies and one RCT were included comparing patients undergoing HALS (n = 500), TLS (n = 263), and EVAR (n = 438) for elective AAA repair. The TLS group had the highest rate of 30-day postoperative reinterventions (p = 0.00056), the longest surgical duration (p = 0.0311), and the highest rate of conversion to open surgery (p < 0.001). TLS was also associated with the most blood loss during surgery, the highest blood transfusion volumes, and the longest length of ICU stay, although these results did not reach statistical significance. Subgroup analysis revealed superior contemporary EVAR outcomes compared to TLS. Laparoscopic surgery (LAS) and EVAR have comparable mortality rates. However, LAS, particularly TLS, is significantly less efficacious than EVAR in terms of intraoperative conversions to open surgery and 30-day reintervention rates. Further controlled trials with larger sample sizes are needed to confirm the evidence.

RESUMO

Fracture Related Infection (FRI) represents one of the biggest challenges for Trauma and Orthopaedic surgery. A better understanding of the microbiological profile should assist with decision-making and optimising outcomes. Our primary aim was to report on the microbiological profile of FRI cases treated over a six-year period at one of Europe's busiest trauma centres. Secondarily, we sought to correlate our findings with existing anti-microbiological protocols and report on diagnostic techniques employed in our practice. All adult cases of FRI treated in our institution between 2016 and 2021 were identified, retrospectively. We recorded patient demographics, diagnostic strategies, causative organisms and antibiotic susceptibilities. There were 330 infection episodes in 294 patients. A total of 463 potentially pathogenic organisms (78 different species) were identified from cultures, of which 57.2% were gram-positive and 39.7% gram-negative. Polymicrobial cultures were found in 33.6% of cases and no causative organism was found in 17.5%. The most prevalent organisms were Staphylococcus aureus (24.4%), coagulase-negative Staphylococci (14%), Pseudomonas aeruginosa (8.2%), Enterobacter species (7.8%) and Escherichia coli (6.9%). Resistant gram-positive organisms (methicillin resistant Staphylococcus aureus or vancomycin-resistant Enterococci) were implicated in 3.3% of infection episodes and resistant gram-negatives (extended-spectrum beta-lactamase, ampC or carbapenemase-producing bacteria) in 13.6%. The organisms cultured in 96.3% of infection episodes would have been covered by our empirical systemic antibiotic choice of teicoplanin and meropenem. To our knowledge, this is the largest reported single-centre cohort of FRIs from a major trauma centre. Our results demonstrate patterns in microbiological profiles that should serve to inform the decision-making process regarding antibiotic choices for both prophylaxis and treatment.
