Hyperbilirubinaemia is a valuable marker for acute appendicitis. Patients with hyperbilirubinaemia are also more likely to have appendiceal perforation or gangrene. Bilirubin should be included in the assessment of patients with suspected appendicitis.

Although there is a reasonable anatomical and oncological basis for these techniques, there are no randomised controlled trials from which to draw confident conclusions and there is insufficient consistent high quality evidence to recommend widespread adoption of CME.

BackgroundStudies suggest that defunctioning stomas reduce the rate of anastomotic leakage and urgent reoperations after anterior resection. Although the magnitude of benefit appears to be limited, there has been a trend in recent years towards routinely creating defunctioning stomas. However, little is known about post-operative complication rates in patients with and without a defunctioning stoma. We compared overall short-term post-operative complications after low anterior resection in patients managed with a defunctioning stoma to those managed without a stoma.MethodsA retrospective cohort study of patients undergoing elective low anterior resection of the rectum for rectal cancer. The primary outcome was overall 90-day post-operative complications.ResultsTwo hundred and three patients met the inclusion criteria for low anterior resection. One hundred and forty (69%) had a primary defunctioning stoma created. 45% received neoadjuvant radiotherapy. Patients with a defunctioning stoma had significantly more complications (57.1 vs 34.9%, p = 0.003), were more likely to suffer multiple complications (17.9 vs 3.2%, p < 0.004) and had longer hospital stays (13.0 vs 6.9 days, p = 0.005) than those without a stoma. 19% experienced a stoma-related complication, 56% still had a stoma 1 year after their surgery, and 26% were left with a stoma at their last follow-up. Anastomotic leak rates were similar but there was a significantly higher reoperation rate among patients managed without a defunctioning stoma.ConclusionPatients selected to have a defunctioning stoma had an absolute increase of 22% in overall post-operative complications compared to those managed without a stoma. These findings support the more selective use of defunctioning stomas.Study registrationRegistered at www.researchregistry.com (UIN: researchregistry3412).

The latest state of the art technological innovations have led to a palpable progression in endoscopic imaging and may facilitate standardisation of practice. One of the most rapidly evolving modalities is artificial intelligence with recent studies providing real-time diagnoses and encouraging results in the first randomised trials to conventional endoscopic imaging. Advances in functional hypoxia imaging offer novel opportunities to be used to detect neoplasia and the assessment of colitis. Three-dimensional volumetric imaging provides spatial information and has shown promise in the increased detection of small polyps. Studies to date of self-propelling colonoscopes demonstrate an increased caecal intubation rate and possibly offer patients a more comfortable procedure. Further development in robotic technology has introduced ex vivo automated locomotor upper gastrointestinal and small bowel capsule devices. Eye-tracking has the potential to revolutionise endoscopic training through the identification of differences in experts and non-expert endoscopist as trainable parameters. In this review, we discuss the latest innovations of all these technologies and provide perspective into the exciting future of diagnostic luminal endoscopy.

This cohort series demonstrates that endoscopic resection of large non-polypoid lesions associated with colitis is feasible and safe using an array of resection methods supporting the role of advanced endoscopic therapeutics for the management of colitis associated dysplasia in a western tertiary endoscopic center.

Combining eastern and western practices for assessment and resection results in safe and effective organ-conserving treatment of complex colorectal lesions. Accurate assessment before and after resection using magnification chromoendoscopy and a lesion-specific approach to resection, incorporating ESD where appropriate, are important factors in achieving these results.
