Mistakes in capsule endoscopy and how to avoid them
Wireless technology means capsule endoscopy is well tolerated, but it is also a drawback
Capsule endoscopy is a noninvasive technique intended for studying the small bowel and/or colon. The capsule endoscope consists of a small, wireless, pill-sized camera that can be swallowed and allows direct visualization of the gastrointestinal mucosa. The design of the capsule differs depending on the part of the gastrointestinal tract to be studied. The small-bowel capsule has one optical dome and is generally used in patients who have suspected bleeding or to identify evidence of active Crohn’s disease. By contrast, the colon capsule has two optical domes, a higher frame rate and can be considered as an alternative to conventional colonoscopy, especially for cases when the examination was incomplete. There is also a new capsule with two optical domes that is designed for the panendoscopic study of both the small bowel and colon.The main characteristic of capsule endoscopy is the wireless technology, which enables it to be very well tolerated. However, this feature is also one of its drawbacks, as the capsule cannot be directly controlled by the physician. The capsule moves through the gut depending solely on intestinal motility, and the examiner is not able to drive it back and forth or to stop it to look more carefully at any finding. Moreover, the visualization relies heavily on the adequacy of intestinal cleansing as rinsing with water and aspiration are not possible. Capsule endoscopists should be aware of these shortcomings, as they directly affect the reading and diagnosis. Here we discuss frequent errors that are made when performing capsule endoscopy, based on the published literature and more than 15 years’ experience
A not-so-black-and-white case of gastrointestinal bleeding
What's causing the black tarry stool, episode of coffee-ground emesis and epigastric pain?
A 60-year-old woman presents at the Emergency Department complaining that she has been passing black, tarry stool since yesterday and had an episode of coffee-ground emesis some hours ago. It is the first time she has noticed these kinds of symptoms. Moreover, she reports episodes of epigastric pain on and off during the past week.The patient has never undergone endoscopy. Her medical history includes diabetes mellitus, hypertension, hyperlipidaemia, gastro-oesophageal reflux disease (GORD), osteoarthritis and alcohol abuse. She admits that she occasionally uses nonsteroidal anti-inflammatory drugs (NSAIDs) to cope with episodes of pain caused by her osteoarthritis and that she took some in the past week. On physical examination she is tachycardic (92 beats per minute) and hypotensive (82/57 mm Hg), but afebrile and her oxygen saturation level is normal. Her abdomen is mildly distended, with some tenderness during deep palpation and increased bowel sounds. Her blood test results at presentation are shown in Table 1. A variceal bleed was suspected, and an emergency upper gastrointestinal endoscopy was performed (see video). Case Question 1 WHAT IS YOUR CLINICAL DIAGNOSIS? A. Oesophageal melanoma
B. Oesophageal infection (e.g. CMV, HSV, Candidiasis)

Personalised nutrition - food for thought
Developing tailored eating advice based on individual nutritional needs
‘Personalised nutrition’ represents any attempt to provide tailor-made healthy eating advice based on the nutritional needs of an individual, as dictated by their behaviour, phenotype and/or genotype and their interactions. Increasing evidence has shown the potential for integrating lifestyle habits, physiology, nutraceuticals, the gut microbiome and genetics into nutritional solutions, specific to the needs of each individual, for maintaining health and preventing disease.

Mistakes in clinical investigation of gastrointestinal motility & function
Symptoms related to abnormal motility and function are very common.
Symptoms related to abnormal gastrointestinal motility and function can occur from the moment food is swallowed to the time stool is passed into the toilet. A recent UEG survey indicated that dysphagia, heartburn, bloating, abdominal pain and changes to bowel habit are each reported by 5–15% of the general population.1 These symptoms are frequent reasons for seeking medical attention from general physicians and for referral to specialist gastroenterologists. Most patients with these symptoms do not have neoplasia, infection or inflammation on initial investigation, but rather so-called functional gastrointestinal symptoms.2,3For patients with mild symptoms, negative tests provide reassurance and simple, symptomatic management might be all that is required (e.g. acid suppression, stool regulation). However, for those with severe symptoms that persist on therapy, ruling out life-threatening disease is not sufficient, and referral to the neurogastroenterology and motility (NGM) laboratory for physiological measurements is often indicated.
Clinical investigations aim to explain the cause of symptoms and establish a diagnosis that can guide rational treatment. Until recently, it could be argued that manometry, scintigraphy, breath tests and related tests rarely provided this information. As a result, only patients with suspected major motility disorders (e.g. achalasia, severe reflux disease or faecal incontinence) were routinely referred to the NGM laboratory for tests. Technological advances, such as high-resolution manometry (HRM), now provide objective measurements not only of motility, but also of function in terms of the movement (and digestion) of ingested material within the gastrointestinal tract. Furthermore, the ability to associate events (such as bolus retention, reflux or gas production) with symptoms provides an indication of visceral sensitivity and can identify what is causing patient complaints. Here, I discuss frequent mistakes in clinical investigation of gastrointestinal motility and function based on a series of consensus documents published by members of the International Working Group for Disorders of Gastrointestinal Motility and Function.

Mistakes in the endoscopic diagnosis and management of Barrett’s oesophagus and how to avoid them
Barrett’s oesophagus is the precursor to oesophageal adenocarcinoma, which carries a poor prognosis,1 and it is likely that all endoscopists and gastroenterologists will encounter Barrett’s oesophagus in their clinical practice.Careful assessment and management of patients who have Barrett’s oesophagus with endoscopic surveillance and endoscopic endotherapy aim to reduce the risk of progression to invasive adenocarcinoma. Advances in endoscopic diagnosis and therapy should, therefore, help to reduce the risk of progression. As with all premalignant conditions and surveillance programmes,2 careful multidisciplinary management of the patient is important to reduce the risk of causing them to become unduly concerned. Here, we present some mistakes that in our experience are commonly made in the endoscopic diagnosis and management of Barrett’s oesophagus and give advice on how to avoid them.

Mistakes in short bowel and how to avoid them
Short bowel manifests as high stomal output or diarrhoea, dehydration and malnutrition.
Short bowel is a condition that occurs after single or multiple intestinal resections. The incidence of short bowel in Europe is 2 per million of the population1–3 and it carries with it lifelong morbidity and mortality. The initial recognition and management of short bowel in the adult population tends to occur in the postoperative period and in the secondary care setting, where specialist input from clinicians experienced in short bowel is often lacking.Normal small bowel length is 275–850 cm.4–7 It is accepted that when the length of small bowel is reduced to less than 200 cm it may be insufficient to enable adequate absorption of fluids and micronutrients. The symptoms of short bowel (often referred to in the literature as short bowel syndrome) are secondary to a reduction in intestinal surface area together with an increased motility of the remaining section of small bowel, with accompanying increased secretion into the lumen. These intestinal secretions vary in their electrolyte content and osmolality depending on the anatomical location, with the highest chloride and potassium loss from gastric secretions and high sodium loss from jejunal secretions.8 Clinically, short bowel manifests itself as a high stomal output or diarrhoea, dehydration and malnutrition. High stomal output or diarrhoea do not, however, necessarily equate immediately to short bowel; conversely, a small bowel longer than 200cm may be insufficient if it is diseased. Here, we discuss some of the pitfalls that are encountered in the recognition and management of short bowel and have suggested an algorithm for assessing and managing patients with a high stomal output. Although some of these pitfalls may appear obvious, they are addressed here because they are commonly encountered in clinical practice (summarised in table 1 at the end of the article).
