Tissue sampling during endoscopic procedures is a fundamental aspect of investigating digestive diseases, with histological examination playing a crucial role in almost every case. Given its prevalence, the potential for mistakes is significant. Therefore, understanding the appropriate indications, techniques, and consequences of tissue sampling is essential for gastroenterologists. Key questions to consider before taking a biopsy or acquiring tissue include: Why? What for? How? How many?

This manuscript addresses these critical questions by detailing the eight most frequent and correctable mistakes in tissue acquisition during endoscopy. The recommendations provided are largely supported by existing guidelines and evidence, with some insights drawn from the authors' professional experience.

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.)

Abdominal CT (computed tomography) is among the most common imaging tests performed for the investigation of acute abdominal pathology. There are many pitfalls that clinicians and radiologists should be aware of when requesting these studies and interpreting the findings. This article covers ten mistakes frequently made with abdominal CT, focusing on gastrointestinal tract and hepatobiliary pathology. These mistakes and their discussions are based on the available literature where possible and thereafter on our clinical experience.

Inflammatory bowel disease (IBD) is a chronic relapsing gastrointestinal disease, often affecting young people during their fertile years. The chronic character of IBD means that lifelong medical treatment is often required. As such, it is not surprising that questions often arise about fertility and pregnancy in patients with IBD. The most important risk factor for adverse pregnancy outcomes in IBD patients is the presence of disease activity during pregnancy. Indeed, negative pregnancy outcomes (e.g. spontaneous abortion, preterm delivery and low birth weight) are associated with disease activity at the time of conception and during pregnancy.
