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.

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.
