Summary

AI Generated

This material addresses nine common mistakes in screening for dysplasia and malignancy in inflammatory bowel disease patients and provides guidance on avoiding them.

Inflammatory bowel disease comprises chronic, progressive, lifelong, and currently incurable gastrointestinal disorders that may be associated with colorectal dysplasia and cancer development.
Technological improvements in disease management and malignancy screening have enabled earlier detection of precancerous lesions and timely resection of premalignant or localised malignant lesions, resulting in improved patient outcomes.
The material presents nine common mistakes encountered in screening for dysplastic and malignant lesions in IBD management, based on clinical experience and an evidence-based approach.
This content would be most relevant to clinicians managing patients with inflammatory bowel disease who perform or oversee dysplasia surveillance.

Abstract

Inflammatory bowel disease (IBD) comprises chronic, progressive, lifelong, and currently incurable disorders of the gastrointestinal tract, which may also be associated with the development of colorectal dysplasia and cancer. However, technological improvements in disease management and malignancy screening over recent decades have enabled earlier detection of precancerous lesions and timely resection of premalignant lesions or even localised malignant lesions, resulting in improved patient outcomes. Here, we discuss mistakes encountered in the screening of dysplastic and malignant lesions when managing patients with IBD. Based on our clinical experience and an evidence-based approach, we present nine common mistakes and how to avoid them.

Abstract

Peritoneal malignancies represent a complex and often misjudged clinical challenge. Historically synonymous with a terminal diagnosis, the advent of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) radically altered the prognosis for selected patients. However, progress has been jeopardised by a series of recurring and preventable errors in diagnosis, staging, and treatment selection. This article delineates the ten most critical pitfalls in managing peritoneal surface malignancies. For each pitfall, we provide evidence-based explanations, concrete clinical examples, and strategic recommendations for avoidance. We emphasise the pivotal role of early multidisciplinary discussion, precise imaging, and timely referral to high-volume expert centres to optimise patient outcomes and offer curative intent where previously there was none.

Abstract

Pancreatic exocrine insufficiency (PEI) is a common yet frequently under-recognised cause of maldigestion, malabsorption, and malnutrition. Although traditionally associated with primary pancreatic disorders such as chronic pancreatitis, cystic fibrosis, pancreatic cancer, or pancreatic surgery, it is now evident that PEI also occurs in a wide range of extra-pancreatic conditions and clinical settings. Advances in diagnostic testing and expanding clinical awareness have improved detection; however, significant misconceptions persist regarding when to suspect PEI; how to interpret diagnostic tests; and how to initiate, optimise, and monitor pancreatic enzyme replacement therapy (PERT). In everyday practice, these errors may lead to delayed diagnosis, inappropriate treatment, persistent symptoms, and preventable nutritional deficiencies. This “Mistakes in…” article highlights common pitfalls in the diagnosis and management of PEI, focusing on inappropriate reliance on faecal elastase testing, failure to recognise secondary causes, undertreatment with PERT, and inadequate nutritional assessment. By addressing these frequent mistakes, we aim to promote a more structured, patient-centred, and evidence-informed approach to PEI that improves clinical outcomes and quality of life.

Abstract

TIPS success is rarely about the procedure alone. It depends on decisions made across the entire clinical pathway.

New in the UEG "Mistakes in…" series: Ferdinande et al., present 10 common mistakes in TIPS for cirrhosis, from referral to long-term follow-up.

Key themes:

• Screen the heart first: cardiac decompensation follows TIPS in up to 20% of patients.

• Refer early: delay costs survival in refractory ascites and high-risk variceal bleeding.

• Prevent encephalopathy by design: careful selection, nutrition, rifaximin, and controlled underdilation.

• Individualise haemodynamic targets and follow up structurally.

Abstract

Abdominal distension and bloating are among the most frequently misunderstood complaints in gastroenterology. They are often used as interchangeable terms, a conceptual mistake that continues to drive diagnostic errors and ineffective treatment. According to Rome IV, bloating and distension may represent either a primary disorder of gut–brain interaction (DGBI) or occur as symptoms with other DGBIs, such as irritable bowel syndrome (IBS), functional dyspepsia (FD) or functional constipation (FC).

Abstract

Ostomy management refers to the care and maintenance of an ostomy and involves various aspects to ensure the individual’s health, comfort, and quality of life. This should involve the patient, a close support system (family and/or friends), and a healthcare team, including ostomy nurses and healthcare professionals specialising in ostomy care.
