Is early bowel resection better than medical therapy for ileocolonic Crohn's disease? A systematic review and meta-analysis.

AIM: There is emerging evidence supporting early bowel resection (EBR) for ileocaecal Crohn's disease (CD) as an alternative to conventional escalation of medical therapy (MT). Here, we present a systematic review and meta-analysis of studies comparing the outcomes of EBR with those of MT in ileocolonic CD, with a focus on ileocaecal disease. METHODOLOGY: The MEDLINE, Embase, CINAHL and Cochrane Central Register of Controlled Trials databases were searched for studies reporting the outcomes of EBR versus MT for ileocolonic CD. The Cochrane tools for assessment of risk of bias were used to assess the methodological quality of studies. RESULTS: Nine records (from 8 studies, with a total of 1867 patients) were included in the analysis. Six studies were observational and two were randomised controlled trials. There was a reduced need for drug therapy in the EBR arm. The rate of intestinal resection at 5 years was 7.8% in the EBR arm and 25.4% in the MT group with a pooled OR of 0.32 (95% CI 0.19, 0.54; p < 0.0001). The EBR group had a longer resection-free survival (HR 0.56, 95% CI 0.38, 0.83; p = 0.004). These outcomes were consistent in a subgroup analysis of patients with ileocaecal disease. Morbidity and quality of life scores were similar across the two groups. CONCLUSION: EBR is associated with a more stable remission compared to initial MT for ileocolonic Crohn's disease. There is enough evidence to support EBR as an alternative to escalation of MT in selected patients with limited ileocaecal disease.

Incorporation of Evidence-Based Surgery into the Curriculum.

Surgeons have historically learned their craft through the apprenticeship model from their mentors. Knowledge and practices acquired this way can rapidly become outdated. Providing high-quality care to patients requires surgeons to keep their knowledge up to date in line with evolving new evidence. The principles of evidence-based medicine (EBM) and its application to surgery, evidence-based surgery (EBS), are pivotal in updating and refining surgical practice. Changing from the conventional practice of surgical education to a structured evidence-based format requires a transformative process in all the levels of surgical practice encompassing trainees and trainers. Equally important is providing an optimal environment to review the evidence and deliver the surgical teaching and incorporate effective assessment tools to monitor the process. In this article, we revisit the levels of evidence and explore the different issues related to EBS such as barriers to EBS, incorporation of EBS to the surgical curriculum and discuss practical ways to implement EBS in the surgical curriculum.

Duodenal biopsies for the diagnosis of coeliac disease: are we adhering to current guidance?

BACKGROUND: The British Society of Gastroenterology guidelines recommend taking at least four duodenal biopsy specimens at the time of upper gastrointestinal (UGI) endoscopy if coeliac disease (CD) is suspected and it has been shown to increase the diagnostic yield of CD. We assessed the compliance to these guidelines within our institution. We then applied measures to improve our compliance rate and assessed the resulting impact on our diagnostic rate of CD. METHODS: We performed a retrospective audit of electronic records for all patients, with no prior diagnosis of CD, who underwent UGI endoscopy with duodenal biopsies between August 2014 and May 2015. We implemented measures to raise awareness among endoscopy users at our institution and carried out a reaudit between February and May 2016. RESULTS: 924 patients were found to be eligible in the first part of the study and 278 in the second part. The proportion of patients who had ≥4 biopsy specimens submitted increased from 21.9% to 60.8% (p<0.001). The diagnostic rate of CD increased from 3.5% in the audit group to 7.6% in the reaudit group (p=0.004). A positive serology result and suspected CD as an indication for biopsy were found to be independent predictors of the likelihood of complying with guidelines. CONCLUSIONS: Our study suggests that taking <4 duodenal biopsy specimens to assess for the presence of CD may lead to the diagnosis of CD being missed. Simple measures can improve the local compliance rate to current guidelines.
