Inflammatory bowel disease (IBD) affects approximately 0.5% to 1% of the population, a prevalence that challenges healthcare systems where it is too rare for primary care but common enough for general gastroenterologists. While some patients experience mild symptoms, others suffer from severe, disabling symptoms and unpredictable disease progression, necessitating a coordinated, multidisciplinary approach to management. Recent advances in understanding IBD pathogenesis, diagnostics, therapies, and surgical techniques have significantly changed IBD management. This Mistakes In article explores common pitfalls in treating IBD, highlighting the complexities and challenges faced by clinicians, and draws on evidence and clinical experience to suggest improvements in patient outcomes.

Acute diverticulitis is an inflammatory complication of diverticulosis and can either be uncomplicated or complicated. Making the distinction between uncomplicated and complicated acute diverticulitis is essential because treatment strategies differ between the two. Here, we discuss 10 mistakes frequently made when managing patients with acute diverticulitis. We focus on using the correct terminology, diagnostic preference and several treatment options, such as omitting or administering antibiotics, radiological interventions and various aspects of surgery. Acute diverticulitis is an important topic because its incidence is rising worldwide and it is becoming a considerable burden on healthcare systems. Most of the discussion included here is evidence-based, supplemented with many years’ combined clinical experience where evidence is lacking.

Barrett’s oesophagus is a premalignant condition of the distal oesophagus predisposing to oesophageal adenocarcinoma. Given the potential for malignant progression and the poor prognosis of eosophageal adenocarcinoma when diagnosed at a symptomatic stage, patients with known Barrett oesophagus undergo regular endoscopic surveillance to detect neoplastic progression at an early and preferably endoscopically, treatable stage. Endoscopic management of early Barrett oesophagus neoplasia consists of a combination of endoscopic imaging, endoscopic resection and endoscopic ablation. Below we discuss a number of mistakes that are frequently made when managing Barrett oesophagus neoplasia and how to avoid them. Much of this discussion draws on existing guidelines (for background reading, check the ESGE Barrett oesophagus guideline), but in many instances the underlying evidence (even in the guideline) is missing and therefore many of our practically driven recommendations are based on common sense and our experience in this field.

It is a difficult task and a great responsibility to evaluate and manage patients with acute - and potentially life-threatening - clinical presentations. It is even more complex to achieve high standards of care for cases on call. Indeed, on-call gastroenterologists, hepatologists and endoscopists are faced with a wide and protean range of gastrointestinal, liver and pancreatic emergencies.  The decision-making process for cases on call is mainly based on information received over the phone, on medical knowledge and clinical experience, and on the resources available. As the degree of confidence in any information given on call may vary, it is of tremendous importance to note, and to document, with precise timing, what has been communicated by, proposed to, and eventually decided with, multiple caregivers (i.e. nurses, emergency physicians, intensive care physicians, surgeons, radiologists etc.)

The diagnosis and management of colorectal cancer in patients who have inflammatory bowel disease is fraught with challenges and the subject is not without controversy. Optimal management requires a thorough knowledge of both diseases as well as the benefits and limitations of colonoscopic surveillance, careful IBD control, high-quality colonoscopy, robust surveillance booking mechanisms, empathic patient education and excellent communication across the multidisciplinary team looking after the patient. Make a mistake and your patient might be subjected to unnecessary life-changing surgery or exposed to an avoidably high lifetime risk of cancer. Here I discuss the mistakes that are often made when managing patients undergoing colitis surveillance. The discussion is evidence based, but where evidence is lacking, the discussion is based on my personal experience of more than 20 years in the field.
