Mistakes in paediatric IBD and how to avoid them
Better clinical outcomes are increasingly being sought in young people with IBD
Around 1 in 10 cases of inflammatory bowel disease (IBD) will present before adulthood, with the median age at presentation being 11–12 years.1 IBD in children and young people is associated with more extensive disease, increased disease activity and a higher rate of complications compared with adult-onset IBD.2 Worldwide, estimates of paediatric IBD prevalence rates are lacking, but data suggest its incidence is increasing.3
Risk factors for paediatric IBD include immigration to high prevalence regions, particularly to countries that have Westernised diets, increasing geographical latitude, and European ancestry (versus belonging to an indigenous population).4 The risk may also be higher in children of certain ethnicities (South Asian, Hispanic, and East Asian).5
While the pathophysiology and clinical presentation of paediatric IBD is well understood, the role of genetics and personalised treatment is currently the focus of a significant amount of international research. Better clinical outcomes—including optimal nutrition, improved growth, better quality of life and increased disease remission rates with decreased occurrence of complications—are increasingly being sought in children and young people with IBD.4
This article discusses mistakes commonly made when identifying, diagnosing and managing children whom are suspected or confirmed to have IBD. The mistakes and discussion are based on published evidence where possible, plus our clinical experience of looking after children with IBD.
Mistakes in tissue sampling during endoscopy and how to avoid them
Tissue acquisition is the most common manoeuvre performed during endoscopy.
Mistakes in managing H. pylori infection and how to avoid them
Careful practice can overcome declining eradication rates for H. pylori treatment.
The sequelae of Helicobacter pylori infection, a known Group 1 carcinogen, can lead to significant morbidity and mortality worldwide. Billions of people are infected with H. pylori, but the incidence of H. pylori infection is declining in many parts of Europe, with a study from the Netherlands showing a decline in seroprevalence from 48% in subjects born between 1935 and 1946 to 16% in those born between 1977 and 1987.1In recent years, however, eradication rates for H. pylori treatment have been falling, which has led to a large number of patients in the community having inadequately managed infections. Most of the problems that have led to the decline in the success of eradication treatment can be easily overcome through careful practice, supported by the robust framework provided by international guidelines. Careful practice includes the correct management of dyspepsia, the appropriate use of diagnostic tests for H. pylori, acceptable, efficacious treatments that enable good patient compliance and adequate follow up to insure eradication has been achieved in all cases. Here, we discuss the mistakes that are made when managing patients infected with H. pylori. Most of the discussion is evidence based, but where evidence is lacking the discussion is based on the authors’ clinical experience of more than 30 years in the field.
Mistakes in NAFLD and how to avoid them
Management of NAFLD requires a multidisciplinary approach.
Nonalcoholic fatty liver disease (NAFLD) is defined as the accumulation of excess fat (triglyceride) in the liver in the absence of excessive alcohol consumption. Disease severity ranges from simple steatosis (nonalcoholic fatty liver [NAFL]) to nonalcoholic steatohepatitis (NASH), fibrosis, or cirrhosis, with the potential to develop hepatocellular carcinoma (HCC) or require liver transplantation.NAFLD is believed to affect up to 25% of the Western population,1 and is fast becoming the leading reason for liver transplantation worldwide.2 It affects up to 70% of those who are obese,3 and is strongly linked to the metabolic syndrome. Management of NAFLD therefore requires a multidisciplinary approach, not only to identify those patients at risk of progressive liver disease, but also to improve long-term liver and cardiovascular morbidity and mortality. Here, we highlight some of the mistakes commonly made by medical practitioners when managing NAFLD, and give an evidence-based (where possible) or experience-based approach to management of the condition.
Mistakes in medical management of IBD and how to avoid them
The subtleties and challenges of contemporary IBD management.
The prevalence of inflammatory bowel disease (IBD) is ~0.5%–1% and rising.1 In many healthcare systems, the frequency of IBD is too rare for it to be managed solely by primary care practitioners, but still common enough to fall within the caseload of general gastroenterologists. Whilst the disease may run a relatively quiescent course, some patients face years of severe, disabling symptoms. The relatively unpredictable prognosis of IBD, combined with the ability of its extraintestinal manifestations to impact multiple organ systems, requires a nimble and individual approach to patient management. Indeed, the treating clinician must liaise closely with colleagues in other disciplines, including nursing, surgery, radiology, histopathology and numerous other medical specialties.Advances in our understanding of IBD pathogenesis and in diagnostic modalities, therapeutic options and surgical techniques for Crohn’s disease and ulcerative colitis have fundamentally altered the landscape of IBD management in the past two decades. The challenge for physicians treating IBD is to leverage these changes to improve patient outcomes, avoiding the many potential pitfalls. Here, we discuss some of the pitfalls that may await the treating clinican, drawing upon evidence when possible and on our clinical experience. If some of these pitfalls seem contradictory, this is deliberately so, to highlight the subtleties and challenges of contemporary IBD management. Many of the pitfalls may also seem somewhat obvious when taken in isolation, and yet we believe them to be relatively common, raising important questions around how we can configure and manage our services to avoid those problems that we all still encounter in practice.
Mistakes in cases on call and how to avoid them
Evaluating and managing GI cases on call is a difficult task.
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.) Here, we discuss 10 mistakes that are often seen when managing GI cases on call. Most of the proposals are based on medical evidence, but others are formed from our own clinical experience.
Mistakes in endoscopic resection and how to avoid them
Endoscopic resection is an advanced technique used to remove superficial lesions.
Endoscopic resection is a widespread, advanced endoscopic technique that can be used to remove superficial lesions in the gastrointestinal tract. Lesions present in all parts of the gastrointestinal tract, such as the oesophagus, stomach, duodenum, small intestine and, above all, colon, can be removed by endoscopic resection. Lesion detection and characterization, the use of appropriate resection devices and methods, and the management of malignant polyps are all important parts of a multistep process that requires training, experience, expertise and a multidisciplinary approach.The diagnostic and therapeutic mistakes discussed here are based on our endoscopic experience. We present the most important mistakes that are often seen in endoscopic resection in our practice and have major consequences for the patient. We propose, from our experience, a simple approach to avoid these mistakes.
Mistakes in GORD diagnosis and how to avoid them
Conditions to be aware of to avoid making an erroneous diagnosis of GORD
According to the Montreal definition, “[gastro-oesophageal reflux disease (GORD)] is a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications.”1 GORD has a negative effect on quality of life and is frequently encountered in clinical practice, with an estimated prevalence of around 24% in Europe.2 In the US, GORD-related healthcare costs account for $9 billion per year.3 A variety of symptoms are associated with GORD—heartburn and regurgitation are typical symptoms, while chest pain, cough and sore throat are considered atypical symptoms—but none is pathognomonic.In case of a typical presentation of GORD in a young patient, and in the absence of alarm signs (e.g. bleeding, dysphagia, weight loss), it is common practice to treat the GORD without investigation. In other cases, upper gastrointestinal endoscopy is usually the first-line examination, more to rule out mucosal complications than to make a positive diagnosis of GORD. Although the presence of erosive oesophagitis is specific to GORD, most patients in whom GORD is suspected based on their clinical presentation have normal endoscopy findings. In this situation, ambulatory reflux monitoring (either pH or pH-impedance monitoring) may be required to identify reflux episodes, to link them with symptom occurrence and then to confirm the clinical diagnosis of GORD. Another common clinical presentation is a patient with symptoms suggestive of GORD that persist despite proton pump inhibitor (PPI) therapy. Indeed 20–60% of patients with GORD-suggestive symptoms are not satisfied with PPI therapy.4,5 After evaluating a patient’s compliance with their treatment, complementary examinations are indicated to determine if resistance to treatment is secondary to persistent GORD, to reflux hypersensitivity or to an erroneous diagnosis of GORD.
Here, we report 10 conditions that clinicians should be aware of to avoid making an erroneous diagnosis of GORD. The discussion draws on a combination of published data and clinical experience.
Mistakes in CT for the acute abdomen and how to avoid them
There are many pitfalls to be aware of when requesting/interpreting abdominal CT scans
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.
Mistakes in the use of PPIs and how to avoid them
PPIs are frequently prescribed—being knowledgeable about them is fundamental.
Proton pump inhibitors (PPIs) inhibit gastric acid secretion by blocking the gastric hydrogen potassium ATPase (H-K-ATPase). When omeprazole, the first PPI, became available in 1988, it soon appeared to be more effective than H2 antagonists, and PPIs rapidly became one of the most prescribed drug classes worldwide.1PPIs have proven highly efficient for the management of gastro-oesophageal reflux disease (GORD), gastroduodenal ulcers and in the treatment of Helicobacter pylori infections. PPIs are, however, also commonly prescribed for chronic complaints of dyspepsia and upper abdominal discomfort, for which there is no proof that gastric acid is an underlying pathophysiological factor. Lately, the safety of long-term PPI use has been the subject of debate, because chronic use of PPIs has been linked to several complications, such as vitamin and mineral malabsorption, pneumonia, gastrointestinal infections and dementia.2 For anyone working in gastroenterology, having knowledge of one of the most prescribed drugs in this field is fundamental. As such, we address nine frequently made mistakes when it comes to the use of PPIs, and also hope to disprove some of the misconceptions about PPI use.
Mistakes in alcoholic liver disease and how to avoid them
ALD is multifaceted—its management poses many difficulties and pitfalls.
Alcohol consumption is the most prevalent aetiology for liver cirrhosis in Europe and the third leading risk factor for overall mortality.1,2 In fact, alcoholic liver cirrhosis accounts for almost half a million deaths a year worldwide, corresponding to 50% of all cases of cirrhosis, according to the World Health Organization (WHO).3 Alcoholic liver disease (ALD) is multifaceted, with several cofactors influencing its progression. Patients abusing alcohol can simultaneously have viral hepatitis B or C, or a genetic disease, such as alpha-1 antitrypsin deficiency or haemochromatosis.Alcohol consumption is usually assessed in pure grams per day and has a direct relationship with liver damage. Daily alcohol consumption of >30 g for men and >20 g for women is considered the cut-off volume at which there is a risk of developing alcohol-related liver disease.4 Besides volume, the pattern of consumption is also a significant factor, with heavy episodic drinking (HED) defined as an intake of 60 g or more of pure alcohol on at least one occasion in the past 30 days. Regarding HED, there is scarce information on the threshold to be applied to this pattern of drinking.5 Although the relationship between alcohol consumption and ALD is well defined, it must be acknowledged that severe disease only develops in a fraction of those who consume excessive amounts of alcohol. Nonetheless, the disease course is very much influenced by the pattern of drinking, with periods of abstinence or heavy drinking clearly altering its progression.5 ALD can present in different stages, ranging from steatosis to more severe disease, such as the clinical syndrome of alcoholic hepatitis, or decompensated liver cirrhosis, which is sometimes complicated by liver cancer. In the setting of alcoholic hepatitis, several scores, such as the Maddrey discriminant function, Glasgow alcoholic hepatitis score (GASH) and ABIC, may be used to evaluate disease severity, predict short-term survival, and decide on the need for specific treatment. Later on, the Lille score, which includes the reduction in serum bilirubin levels at day 7, evaluates the response to prednisolone after one week, in order to decide whether to continue or stop treatment.5 Despite being a frequent disease, the different aspects of ALD mean that its management still poses many difficulties and pitfalls. In this article we discuss frequent mistakes in ALD, based on the current guidelines and some paradigmatic real-life cases.
Mistakes in EoE and how to avoid them
EoE is the second-most frequent cause of chronic oesophagitis.
Eosinophilic oesophagitis (EoE) is a chronic immune-mediated inflammatory condition that is confined to the oesophagus. Clinically, EoE is characterized by symptoms of oesophageal dysfunction; histologically, by eosinophil-predominant inflammation.1,2 At present, EoE is the second-most frequent cause of chronic oesophagitis (gastro-oesophageal reflux disease [GORD] is the primary cause) and the foremost cause of dysphagia and food impaction in young adults and children.The first descriptions of EoE date back to the early 1990s,3,4 but at that time the condition was largely underappreciated and treated as GORD. Recognition of EoE grew with the rapid increase of paediatric and adult patients diagnosed since 2003, but so did confusion surrounding diagnostic criteria and treatment. The first consensus guidelines for the diagnosis and management of EoE were published in 2007 and were instrumental in bringing EoE to light as a distinct new condition.5 Since 2007, the diagnostic criteria for EoE have constantly and rapidly changed. New evidence for therapeutic agents has mounted, especially during the past 5 years. Here, we discuss the critical pitfalls that frequently occur in daily practice when dealing with EoE patients. The discussion is evidence based and in line with the recommendations included in the updated guidelines for diagnosis and management of EoE in children and adults.6
Mistakes in liver function test abnormalities and how to avoid them
Liver function tests (LFTs) are routinely used to screen for liver disease, but the assessment of LFTs can be challenging. The LFT itself must be clearly understood and the results interpreted in light of the specific clinical setting.
Liver function tests (LFTs) are routinely used to screen for liver disease. A correct interpretation of LFT abnormalities may suggest the cause, severity, and prognosis of an underlying disease. Once the diagnosis has been established, sequential LFT assessment can be used to assess treatment efficacy.Abnormal LFTs are frequently encountered in clinical practice, since elevation of at least one LFT occurs in more than 20% of the population.1 Many patients with abnormal LFTs, however, do not suffer from structural liver disease, since these tests can be influenced by factors unrelated to significant liver damage or liver function loss. During normal pregnancy, for example, serum albumin levels fall due to plasma volume expansion, and alkaline phosphatase (ALP) levels rise due to placental influx. Patients who have elevated transaminase levels may not suffer from liver disease, but rather from cardiac or skeletal muscle damage. Conversely, patients who suffer from advanced liver disease, such as chronic hepatitis or compensated liver cirrhosis, may have normal LFTs.
In short, the assessment of LFTs can represent a challenge for physicians. The observations above demonstrate the need for a firm understanding of the individual LFT, and the ability to interpret the results in the light of a specific clinical setting. Such an understanding is not merely a goal on its own, but may serve as a template to avoid mistakes in interpreting LFT abnormalities. In the following sections, we discuss several mistakes frequently made in the interpretation of LFTs and how to avoid them. Most of the discussion is evidence based, but where evidence is lacking the discussion is based on extensive clinical experience.
Mistakes in managing perianal disease and how to avoid them
Perianal disease is very common and can impair quality of life significantly. It is crucial to identify the serious causes of these symptoms, but also to reduce the burden of the less dangerous conditions that nevertheless can be debilitating and interfere with an individual’s work and life.
Perianal disease takes many forms, is very common and can impair quality of life significantly. The symptoms of perianal disease, including pain, bleeding, discharge and pruritus, are common to several conditions that are sometimes difficult to disentangle.
It is crucial to identify the serious causes of perianal symptoms, but also to reduce the burden of the less dangerous conditions that nevertheless can be debilitating and interfere with an individual’s work, social or intimate life. Below we discuss some of the frequent and important mistakes made in the management of perianal disease based, where possible, on evidence, and where not, on clinical experience.
Mistakes in endoscopy and how to avoid them
Diagnostic and therapeutic mistakes discussed in the context of evidence and endoscopic experience.
Upper and lower gastrointestinal endoscopy examinations are performed daily as routine diagnostic procedures in a large number of patients with nonspecific indications, such as heartburn, pain, anaemia, bleeding, workup of portal hypertension and so on.Most of the examinations will point to a classic diagnosis (e.g. peptic disease, cancer, variceal management), but sometimes we see patients who've had multiple diagnostic endoscopic procedures in the previous few months with nonconclusive findings. The diagnostic mistakes discussed here are those that sprang to mind based on our endoscopic experience and they are discussed in an evidence-based approach. For therapeutic endoscopic procedures (e.g. ERCP and resections), we present the most important mistakes that are often seen in our practice and have major consequences for the patient. We propose, from our experience, a simple approach to avoid these mistakes.
Mistakes in paediatric functional constipation diagnosis and treatment and how to avoid them
Have a look at the major mistakes that are made when diagnosing and treating children with functional constipation.
Constipation is a bothersome problem for many children. It may present as one or more of the following: infrequent bowel movements with faecal incontinence, hard and often large stools, painful defecation and abdominal pain. No organic cause of the constipation can be found in approximately 95% of children—these children suffer from functional constipation. The prevalence of functional constipation ranges between 0.7% and 29.6% and it occurs in girls more often than in boys (ratio 2.1:1).1The diagnosis of functional constipation is based on the paediatric diagnostic Rome criteria for functional gastrointestinal disorders.2,3 Additional investigations are indicated only if the diagnosis is not clear or in order to rule out an underlying organic disease, such as Hirschsprung disease.4 Education, demystification of constipation, following a reward-based toilet program and keeping a daily bowel diary form part of the nonpharmacological management process.4 Disimpaction, maintenance treatment and weaning of medication are all elements of pharmacological treatment.4 Polyethylene glycol (PEG) is the first-choice laxative for both disimpaction and maintenance treatment; however, if PEG is not available or is poorly tolerated, lactulose is recommended. Other laxatives are available as a second-line or additional treatment if treatment with PEG is insufficient. Here we discuss the major mistakes that are made when diagnosing and treating children with functional constipation. The discussion that follows is evidence based in the majority of cases, but where evidence is lacking the discussion is based on the lead author’s clinical experience of more than 20 years in the field as a paediatric gastroenterologist.
Mistakes in irritable bowel syndrome and how to avoid them
Learn more about the mistakes that can be made when diagnosing and managing IBS!
Around 11% of the worldwide population experience irritable bowel syndrome (IBS), making it one of the most frequent gastroenterological diagnoses.1 The symptoms of IBS include abdominal pain associated with unpredictable bowel habits and variable changes in the form and frequency of stool.2While all patients with IBS suffer from recurrent bouts of abdominal pain, their bowel habits are varied: around one-third suffer predominantly with diarrhoea (IBS-D), one-fifth experience predominantly constipation (IBS-C) and half have an erratic mixed pattern of both diarrhoea and constipation (IBS-M).3 This very heterogeneous condition undoubtedly has multiple causes and an individualized approach to management and treatment is required. Here I discuss the mistakes most frequently made when diagnosing and managing IBS. The mistakes and discussion that follow are based, where possible, on published data and failing that on many years of my own clinical experience.
Mistakes in the management of acute pancreatitis and how to avoid them
Critical decision-making points & pitfalls
Acute pancreatitis is a common inflammatory disorder of the pancreas and its incidence is increasing among hospitalized patients worldwide.
The main symptoms include severe upper abdominal pain (often sudden onset), nausea, vomiting, bloating and the development of ileus. In many cases jaundice will also be present. The diagnosis, as agreed by international consensus, can be established by fulfilling two of the following three criteria: upper abdominal pain of sudden onset, elevation of either serum lipase or amylase activity to greater than three times the upper limit of normal, and imaging findings consistent with inflammation of the pancreas.4–6
By far the most common risk factors for the development of acute pancreatitis are excessive alcohol consumption and gallstone disease. Several mutations have been identified that, in combination with nongenetic factors or alone, can lead to pancreatitis. Certain drugs are known to be associated with the development of pancreatitis and smoking might also increase the probability of it developing. 80–85% of patients diagnosed with the disease will have mild disease and make an uneventful recovery with little more than adequate fluid therapy and analgesia needed to support them. The remaining patients, however, will suffer from moderately severe to severe acute pancreatitis, with the development of pancreatic necrosis, severe sepsis or abdominal compartment syndrome. These patients are at immediate danger of multiorgan failure and death and require multidisciplinary intensive care, organ support and often pancreatic interventions conducted by experienced investigators. Since it is difficult to predict outcomes and complications develop during the disease course, treatment in specialized centres that have a high case load is recommended.4
Here, we discuss critical decision-making points and pitfalls frequently occurring when managing patients with acute pancreatitis. The discussion is based on the medical literature and many years of clinical experience.
In 2009, it was the most frequent diagnosis in patients discharged from GI services in the US and the fifth leading cause of in-hospital mortality.1 Because of this high disease burden, acute pancreatitis is also a substantial contributor to healthcare spending, accounting for an estimated annual spend of US$4–7 million per million inhabitants in western countries.2,3
Mistakes in endoscopic retrograde cholangiopancreatography and how to avoid them
Endoscopic retrograde cholangiopancreatography (ERCP) is a widespread technique used for the treatment of different diseases of the bile and pancreatic ducts.
Endoscopic retrograde cholangiopancreatography (ERCP) is a widespread technique used for the treatment of different diseases of the bile and pancreatic ducts. The technique is, however, associated with rare but potentially severe morbidity.Some of the adverse events associated with ERCP are directly linked to commonly made mistakes and can, therefore, be prevented. Here, we discuss 10 common and/or high-impact mistakes that are made during ERCP and how they can be avoided.
