RESUMO
INTRODUCTION: The aim of this study was to explore whether there were any differences in consultant colorectal surgeon training and adjusted 90-day postoperative colorectal cancer mortality rates (AMR). METHODS: We undertook a retrospective analysis of outcomes data published on the Association of Coloproctology of Great Britain and Ireland (ACPGBI) website. A total of 51,562 procedures for patients in England diagnosed with large bowel cancer between 2010 and 2015, registered under 551 consultants were included. Consultants were split into two cohorts. The first group were the pre-Calman Trained Consultants (pre-CTr), who completed their training before 1998. The second group-the post-Calman Trained Consultants (post-CTr)-included those who received their Certificate of Completion of Training (CCT) under the Calman Training Principles (CTC, 1998-2007) and the Modernising Medical Careers Curriculum (MMC, 2008 and onwards). The outcome measure was an AMR. RESULTS: The pre-CTr cohort (n=84) consisted of 3.6% female colorectal consultants (n=3/84), whereas the post-CTr cohort (n=467) consisted of 14.3% female colorectal consultants (n=67/467) (p=0.006). In this cross-sectional analysis over 5 years, the average pre-CTr undertook a greater number of colorectal resections than their post-CTr peers: median procedures (interquartile range, IQR): 104 (59) vs 89 (57) respectively, p=0.008. The median AMR was significantly greater among pre-CTrs compared with post-CTrs, median AMR (IQR): 2.7% (2.0) vs 2.1% (2.9), p=0.022. CONCLUSIONS: These data indicate that the implementation of the MMC and Calman training principles for colorectal training is associated with a statistically lower AMR compared with other historical training periods. This merits further exploration.
RESUMO
INTRODUCTION: Evidence suggests that delaying an appendicectomy for up to 24 hours does not increase the risk of complicated appendicitis. Appendicoliths are a risk factor for perforation. No study has explored the temporal relationship between appendicolith presence and time to perforation. In this retrospective cohort study, we hypothesise that the presence of an appendicolith confirmed on preoperative computerised tomography scan (pCT) leads to a shorter time to complicated appendicitis. METHODS: We undertook a retrospective single-centre study of patients admitted between 2018 and 2020. Inclusion criteria included: age ≥18 years, appendicitis confirmed on histopathology following an operation and a pCT scan. Complicated appendicitis was defined intraoperatively as an appendicular abscess, gangrenous or perforated appendix. RESULTS: Some 310 patients were included in the study. Forty-five per cent presented with complicated appendicitis (n = 138). Appendicoliths were present in 79 (25.5%) patients. Multivariate logistic regression identified an appendicolith as a significant risk factor for perforation (odds ratio 3.50, 95% confidence interval [CI] 1.16-10.59; p = 0.027). Within the first 12 hours of admission, patients with an appendicolith accounted for a significantly greater proportion of those with complicated appendicitis intraoperatively compared with those without (56.7% vs 43.3%, respectively; p = 0.003). Within 12 hours of admission, those with an appendicolith were 2.05 times more likely to suffer from complicated appendicitis than those without (95% CI 1.28-3.29). CONCLUSIONS: Patients with an appendicolith appendicitis should be considered for an early appendicectomy. Future large-scale multicentre prospective studies are required to explore this further, perhaps informing future guidelines.
