RESUMEN

BACKGROUND: The use of cerebral oximetry monitoring in the care of extremely preterm infants is increasing. However, evidence that its use improves clinical outcomes is lacking. METHODS: In this randomized, phase 3 trial conducted at 70 sites in 17 countries, we assigned extremely preterm infants (gestational age, <28 weeks), within 6 hours after birth, to receive treatment guided by cerebral oximetry monitoring for the first 72 hours after birth or to receive usual care. The primary outcome was a composite of death or severe brain injury on cerebral ultrasonography at 36 weeks' postmenstrual age. Serious adverse events that were assessed were death, severe brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and late-onset sepsis. RESULTS: A total of 1601 infants underwent randomization and 1579 (98.6%) were evaluated for the primary outcome. At 36 weeks' postmenstrual age, death or severe brain injury had occurred in 272 of 772 infants (35.2%) in the cerebral oximetry group, as compared with 274 of 807 infants (34.0%) in the usual-care group (relative risk with cerebral oximetry, 1.03; 95% confidence interval, 0.90 to 1.18; P = 0.64). The incidence of serious adverse events did not differ between the two groups. CONCLUSIONS: In extremely preterm infants, treatment guided by cerebral oximetry monitoring for the first 72 hours after birth was not associated with a lower incidence of death or severe brain injury at 36 weeks' postmenstrual age than usual care.

RESUMEN

BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS: We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS: We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS: Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

RESUMEN

BACKGROUND: When commencing enteral feeding, patients and families will want to know the likelihood of returning to an oral diet. There is a paucity of data on the prognosis of patients with gastrostomies. We describe a large dataset of patients, which identifies factors influencing gastrostomy removal and assesses the likelihood of the patient having at home enteral nutrition. METHODS: Retrospective data was collected on patients from Sheffield Teaching Hospitals who had received a gastrostomy and had outpatient enteral feeding between January 2016 and December 2019. Demographic data, indication and outcomes were analysed. RESULTS: A total of 451 patients were assessed, median age: 67.7. 183/451(40.6%) gastrostomies were for head and neck cancer, 88/451 (19.5%) for stroke, 28/451 (6.2%) for Motor Neuron Disease, 32/451 (7.1%) for other neurodegenerative causes, 120/451 (26.6%) other. Of the 31.2% who had their gastrostomy removed within 3 years, head and neck cancer was the most common indication (58.3%) followed by stroke (10.2%), Motor Neuron Disease (7.1%) and other neurodegenerative diseases (3.1%). Gastrostomy removal was significantly influenced by age, place of residence, and having head and neck cancer (p < 0.05). There was the greatest likelihood of removal within the first year (24%). 70.5% had enteral feeding at home. CONCLUSION: This large cohort study demonstrates 31.2% of patients had their gastrostomy removed within 3 years. Head and neck cancer patients, younger age and residing at home can help positively predict removal. Most patients manage their feeding at home rather than a nursing home. This study provides new information on gastrostomy outcomes when counselling patients to provide realistic expectations.

RESUMEN

BACKGROUND AND AIMS: International endoscopy societies vary in their approach for credentialing individuals in endoscopic ultrasound (EUS) to enable independent practice; however, there is no consensus in this or its implementation. In 2019, the Joint Advisory Group on GI Endoscopy (JAG) commissioned a working group to examine the evidence relating to this process for EUS. The aim of this was to develop evidence-based recommendations for EUS training and certification in the UK. METHODS: Under the oversight of the JAG quality assurance team, a modified Delphi process was conducted which included major stakeholders from the UK and Ireland. A formal literature review was made, initial questions for study were proposed and recommendations for training and certification in EUS were formulated after a rigorous assessment using the Grading of Recommendation Assessment, Development and Evaluation tool and subjected to electronic voting to identify accepted statements. These were peer reviewed by JAG and relevant stakeholder societies before consensus on the final EUS certification pathway was achieved. RESULTS: 39 initial questions were proposed of which 33 were deemed worthy of assessment and finally formed the key recommendations. The statements covered four key domains, such as: definition of competence (13 statements), acquisition of competence (10), assessment of competence (5) and postcertification mentorship (5). Key recommendations include: (1) minimum of 250 hands-on cases before an assessment for competency can be made, (2) attendance at the JAG basic EUS course, (3) completing a minimum of one formative direct observation of procedural skills (DOPS) every 10 cases to allow the learning curve in EUS training to be adequately studied, (4) competent performance in summative DOPS assessments and (5) a period of mentorship over a 12-month period is recommended as minimum to support and mentor new service providers. CONCLUSIONS: An evidence-based certification pathway has been commissioned by JAG to support and quality assure EUS training. This will form the basis to improve quality of training and safety standards in EUS in the UK and Ireland.

RESUMEN

INTRODUCTION: There are limited studies comparing the safety and effectiveness of Radiologically Assisted Gastrostomies (RAGs) against Percutaneous Endoscopic Gastrostomies (PEGs). The Sheffield Gastrostomy Score (SGS) can be used to help predict 30-day mortality, more information is needed on its validity in RAGs. Our aim is to compare mortality between RAGs (Radiologically Inserted Gastrostomies (RIGs) and Per-oral Image Guided Gastrostomies (PIGs)) with PEGs and validate the SGS. METHOD: Data on gastrostomies newly inserted in three hospitals from 2016-2019 were retrospectively collected. Demographics, indication, insertion date, date of death, inpatient status and blood tests (albumin, CRP and eGFR) were recorded. RESULTS: 1977 gastrostomies were performed: Gastrostomy mortality at 7 days was 1.3% and at 30 days was 6%. There was a 5% 30-day mortality for PEGs, 5.5% RIGs, 7.2% PIGs (p = 0.215). Factors increasing 30 day mortality were age ≥60 years (p = 0.039), albumin <35 g/L (p = 0.005), albumin <25 g/L (p < 0.001) and CRP ≥10 mg/L (p < 0.001). For patients who died within 30 days; 0.6% had an SGS of 0, 3.7% = 1, 10.2% = 2 and 25.5% = 3, with similar trends for RAGs and PEGs. ROC curves showed the area under the curve for all gastrostomies, RAGs and PEGs as 0.743, 0.738, 0.787 respectively. DISCUSSION: There was no significant difference between 30-day mortality for PEGs, RIGs and PIGs. Factors predicting risk include age ≥60 years, albumin <35 g/L, albumin <25 g/L and CRP ≥10 mg/L. The SGS has been validated in this study for PEGs and for the first time in RAGs as well..

RESUMEN

The European Society of Gastrointestinal Endoscopy and United European Gastroenterology have defined performance measures for upper and lower gastrointestinal, pancreaticobiliary, and small-bowel endoscopy. Quality indicators to guide endoscopists in the growing field of advanced endoscopy are also underway. We propose that equal attention is given to developing the entire advanced endoscopy team and not the individual endoscopist alone.We suggest that the practice of teams intending to deliver high quality advanced endoscopy is underpinned by six crucial principles concerning: selection, acceptance, complications, reconnaissance, envelopment, and documentation (SACRED).

RESUMEN

BACKGROUND: Pancreatic exocrine insufficiency (PEI) and subsequent malnutrition can be difficult to diagnose but lead to sarcopenia and increased mortality and morbidity even in benign disease. Digital skeletal muscle analysis has been increasingly recognised as a tool to diagnose sarcopenia. OBJECTIVE: The aim of the study was to assess the prevalence of sarcopenia in patients with PEI secondary to benign disease using novel skeletal muscle recognition software. METHODS: Prospective recruitment of patients referred for endoscopic ultrasound (EUS) with suspected pancreatic pathology. Patients with suspected pancreatic cancer on initial computed tomography (CT) were excluded. The diagnosis of chronic pancreatitis (CP) was based on CT and EUS findings. PEI was assessed with faecal elastase-1. Digital measurement of skeletal muscle mass identified sarcopenia, with demographic and comorbidity data also collected. RESULTS: PEI was identified in 45.1% (46/102) of patients recruited, and 29.4% (30/102) had changes of CP. Sarcopenia was significantly more prevalent in PEI 67.4% (31/46) than no-PEI 37.5% (21/56) (37.5%), regardless of CP changes (p < 0.003). The prevalence of sarcopenia (67% vs. 35%; p = 0.02) and sarcopenic obesity (68.4% vs. 25%; p = 0.003) was significantly higher when PEI was present without a radiological diagnosis of CP. Multivariate analysis identified sarcopenia and diabetes to be independently associated with PEI (odds ratio 4.8 and 13.8, respectively, p < 0.05). CONCLUSION: Sarcopenia was strongly associated with PEI in patients undergoing assessment for suspected benign pancreatic pathology. Digital skeletal muscle assessment can be used as a tool to aid identification of sarcopenia in patients undergoing CT scan for pancreatic symptoms.

RESUMEN

While outcomes for neonates with congenital heart disease have improved, it is apparent that substantial variability exists among centers with regard to the multidisciplinary approach to care for this medically fragile patient population. We endeavored to understand the landscape of neonatal cardiac care in the United States. A survey was distributed to physicians who provide neonatal cardiac care in the United States regarding (1) collaborative efforts in care of neonates with congenital heart disease (CHD); (2) access to neonatal cardiac training; and (3) barriers to the implementation of protocols for neonatal cardiac care. Responses were collected from 10/2018 to 6/2019. We received responses from 172 of 608 physicians (28% response rate) from 89 centers. When compared to responses received from physicians at low-volume centers (< 300 annual bypass cases), those at high-volume centers reported more involvement from the neurodevelopmental teams (58% vs. 29%; P = 0.012) and a standardized transition to outpatient care (68% vs. 52%; P = 0.038). While a majority of cardiothoracic surgery and anesthesiology respondents reported multidisciplinary involvement, less than half of cardiology and neonatology supported this statement. The most commonly reported obstacles to multidisciplinary engagement were culture (61.6%) and logistics (47.1%). Having a standardized neonatal cardiac curriculum for neonatal fellows was positively associated with the perception that multidisciplinary collaboration was "always" in place (53% vs. 40%; P = 0.09). There is considerable variation among centers in regard to personnel involved in neonatal cardiac care, related education, and perceived multidisciplinary collaboration among team members. The survey findings suggest the need to establish concrete standards for neonatal cardiac surgical programs, with ongoing quality improvement processes.

RESUMEN

AIM: The aim of this study was to evaluate the effects of a carbon dioxide pneumoperitoneum on cerebral and renal oxygenation and oxygen extraction, in a cohort of infants from the neonatal intensive care unit, undergoing laparoscopic gastrostomy. METHODS: After institutional review board approval, between February 2018 and June 2019, infants 0-3 mo corrected age, undergoing laparoscopic gastrostomy tube placement, were included. Strict exclusion criteria created a homogeneous cohort. Cerebral and renal tissue oxygen saturation (rSO2) by near-infrared spectroscopy, skin surface oxygen saturation (SpO2), by pulse oximetry, and amplitude-integrated electroencephalography were measured. Monitoring was divided into preoperative, intraoperative and postoperative time periods. Cerebral and renal fractional tissue oxygen extraction was calculated using arterial (SpO2) and tissue oxygen saturation (rSO2): (SpO2-rSO2SpO2)X100. Data were averaged into one-minute epochs and significant changes from baseline during the intraoperative and postoperative periods were detected using one-way analysis of variance with repeated measures. RESULTS: This pilot study examined sixteen infants, born at a median gestational age of 34.2 wk (range: 23.0-40.6) with a median corrected age of 42.9 wk (range: 40.0-46.3) at operation. None had seizure activity or altered sleep-wake cycles. No statistically significant variations in cerebral and renal tissue oxygenation and extraction were observed. Pulse oximetry did demonstrate significant variation from baseline on analysis of variance, but post hoc analysis did not identify any one specific time point at which this difference was significant. CONCLUSIONS: During a short infant laparoscopic procedure, no significant alteration in cerebral or renal oxygenation or oxygen extraction was observed. No seizure activity or changes in infant sleep-wake cycles occurred.

RESUMEN

OBJECTIVES: The aim of this study was to document the process of achieving full enteral feeding in infants with omphalocele and to identify factors that affect feeding success. METHODS: After institutional review board approval (study no. 5100169), 123 infants with omphalocele, born between 1993 and 2011 were reviewed. Mortalities were excluded. All survivors had complete follow-up. Variables suspected to impact enteral feeding in infants with non-giant versus giant omphalocele were compared. Independent t test, Mann-Whitney, and χ test were used. Regression evaluated for variable independence. RESULTS: Of 123 infants with omphalocele, 97 (79%) survived, 62/97 (64%) had non-giant, and 35/97 (36%) giant omphalocele. For survivors, the mean gestational age was 37 ±â€Š4 weeks with median follow-up of 4.4 years (range: 1.4-7.4 years). The median time to full feeds was 4 days (range: 0-85 days) for non-giant versus 8 days (range: 1-96 days) for giant, a significant difference (P < 0.01). Breast milk significantly decreased time to full feeds independent of omphalocele size. Giant omphalocele infants had a significantly higher incidence of respiratory insufficiency at birth (P < 0.01) and sac rupture (P = 0.02), but fewer chromosomal anomalies (P = 0.04). Respiratory insufficiency at birth (P < 0.01) and gastroesophageal reflux disease (P < 0.01) independently delayed feeding in omphalocele infants. CONCLUSIONS: Infants with non-giant omphalocele can achieve full enteral feeds within the first week of life, but giant omphalocele infants require significantly more time. Breast milk independently promotes feeding success whereas gastroesophageal reflux disease and respiratory insufficiency at birth independently delay feeding in infants with omphalocele.

RESUMEN

Importance: Preterm infants must establish regular respirations at delivery. Sustained inflations may establish lung volume faster than short inflations. Objective: To determine whether a ventilation strategy including sustained inflations, compared with standard intermittent positive pressure ventilation, reduces bronchopulmonary dysplasia (BPD) or death at 36 weeks' postmenstrual age without harm in extremely preterm infants. Design, Setting, and Participants: Unmasked, randomized clinical trial (August 2014 to September 2017, with follow-up to February 15, 2018) conducted in 18 neonatal intensive care units in 9 countries. Preterm infants 23 to 26 weeks' gestational age requiring resuscitation with inadequate respiratory effort or bradycardia were enrolled. Planned enrollment was 600 infants. The trial was stopped after enrolling 426 infants, following a prespecified review of adverse outcomes. Interventions: The experimental intervention was up to 2 sustained inflations at maximal peak pressure of 25 cm H2O for 15 seconds using a T-piece and mask (n = 215); standard resuscitation was intermittent positive pressure ventilation (n = 211). Main Outcome and Measures: The primary outcome was the rate of BPD or death at 36 weeks' postmenstrual age. There were 27 prespecified secondary efficacy outcomes and 7 safety outcomes, including death at less than 48 hours. Results: Among 460 infants randomized (mean [SD] gestational age, 25.30 [0.97] weeks; 50.2% female), 426 infants (92.6%) completed the trial. In the sustained inflation group, 137 infants (63.7%) died or survived with BPD vs 125 infants (59.2%) in the standard resuscitation group (adjusted risk difference [aRD], 4.7% [95% CI, -3.8% to 13.1%]; P = .29). Death at less than 48 hours of age occurred in 16 infants (7.4%) in the sustained inflation group vs 3 infants (1.4%) in the standard resuscitation group (aRD, 5.6% [95% CI, 2.1% to 9.1%]; P = .002). Blinded adjudication detected an imbalance of rates of early death possibly attributable to resuscitation (sustained inflation: 11/16; standard resuscitation: 1/3). Of 27 secondary efficacy outcomes assessed by 36 weeks' postmenstrual age, 26 showed no significant difference between groups. Conclusions and Relevance: Among extremely preterm infants requiring resuscitation at birth, a ventilation strategy involving 2 sustained inflations, compared with standard intermittent positive pressure ventilation, did not reduce the risk of BPD or death at 36 weeks' postmenstrual age. These findings do not support the use of ventilation with sustained inflations among extremely preterm infants, although early termination of the trial limits definitive conclusions. Trial Registration: clinicaltrials.gov Identifier: NCT02139800.

RESUMEN

There are two main types of oesophageal cancer, oesophageal squamous cell carcinoma (OSCC) and oesophageal adenocarcinoma (OAC). They present in the same manner and both carry a five-year survival of only 16%. In the UK there is a 2:1 male to female ratio for oesophageal cancer. Peak incidence at presentation is in the 65-75 age group, with 95% of cases presenting in those over 50. Smoking is a major risk factor for both types and is linked to an estimated 66% of cases in the UK. OSCC is linked to alcohol, smoking, and chewing betel quid. OAC is associated with the presence of GORD, and its duration, and obesity (especially increased waist circumference). Oesophageal cancer commonly presents with dysphagia or odynophagia. This can be associated with weight loss and vomiting. All patients with recent onset dysphagia should be referred for rapid access endoscopy. Referral for urgent endoscopy should still be considered in the presence of dysphagia regardless of previous history or medication. Dysphagia is not always present so all patients with alarm symptoms should be considered for endoscopy. NICE recommends referral for urgent direct access upper GI endoscopy to assess for oesophageal cancer for patients with dysphagia or aged 55 and over with weight loss and any of the following: upper abdominal pain; reflux; dyspepsia.

RESUMEN

The common presentation of coeliac disease has shifted from the historically classical symptoms of malabsorption in childhood to non-classical symptoms in adulthood such as irritable bowel syndrome-type symptoms, anaemia, chronic fatigue, change in bowel habit, abdominal pain and osteoporosis. A combination of coeliac serology and duodenal biopsy is required to diagnose coeliac disease in adults. Testing for IgA-tissue transglutaminase antibodies should be carried out as a first-line screening test. Advise patients to eat a gluten-containing diet for six weeks before their investigations to ensure the serological and histological results are not affected. A confirmatory duodenal biopsy is mandatory to ensure that patients are correctly diagnosed with coeliac disease. A lifelong strict gluten-free diet is the only effective treatment currently available. All patients should be referred to a specialist dietitian for guidance and support. Annual follow-up can begin when the disease is stable and patients are managing well on their diet.

RESUMEN

Nitrate and nitrite are commonly thought of as inert end products of nitric oxide (NO) oxidation, possibly carcinogenic food additives, or well-water contaminants. However, recent studies have shown that nitrate and nitrite play an important role in cardiovascular and gastrointestinal homeostasis through conversion back into NO via a physiological system involving enterosalivary recirculation, bacterial nitrate reductases, and enzyme-catalyzed or acidic reduction of nitrite to NO. The diet is a key source of nitrate in adults; however, infants ingest significantly less nitrate due to low concentrations in breast milk. In the mouth, bacteria convert nitrate to nitrite, which has gastro-protective effects. However, these nitrate-reducing bacteria are relatively inactive in infants. Swallowed nitrite is reduced to NO by acid in the stomach, affecting gastric blood flow, mucus production, and the gastric microbiota. These effects are likely attenuated in the less acidic neonatal stomach. Systemically, nitrite acts as a reservoir of NO bioactivity that can protect against ischemic injury, yet plasma nitrite concentrations are markedly lower in infants than in adults. The physiological importance of the diminished nitrate→nitrite→NO axis in infants and its implications in the etiology and treatment of newborn diseases such as necrotizing enterocolitis and hypoxic/ischemic injury are yet to be determined.

RESUMEN

Gastro-oesophageal reflux disease (GORD) is defined as a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Many patients with GORD complications such as oesophagitis, and up to a third of patients with Barrett's oesophagus have no reflux or heartburn symptoms. Conversely, patients can be symptomatic even when normal reflux levels are found and there is an absence of mucosal damage. Significant GORD symptoms occur at least once a week in 8.8-26% of Europeans, with equal prevalence of symptoms in men and women. The frequency and severity of symptoms do not accurately predict the degree of oesophageal damage. If patients with GORD also describe symptoms of dyspepsia this should be considered first with H. py/oritesting or direct referral for gastroscopy if the patient is over 55 given the risk of gastric cancer in these patients. Oesophageal disease can account for up to 20% of cases of chronic cough. Symptoms of GORD occur in more than 45% of patients with asthma, and erosive oesophagitis on endoscopy has a 50% higher likelihood of a diagnosis of asthma. GORD is a risk factor for Barrett's oesophagus and oesophageal adenocarcinoma. The risk increases with duration, severity and frequency. Endoscopy should not be routinely offered at initial presentation unless the patient has dysphagia or other symptoms suggestive of upper GI cancer. Smoking cessation and weight loss are beneficial in reducing GORD symptoms. Abdominal obesity causes GORD by elevating intra-abdominal pressure, which promotes reflux and the development of hiatus hernia. GORD symptoms are increased by 70% among daily smokers who have been smoking for more than 20 years.

RESUMEN

Gastric cancer often presents late and the mortality ratio remains one of the highest compared with more common cancers. Early diagnosis improves survival in this potentially curable cancer. Men are twice as likely as women to develop gastric cancer. The vast majority (96%) of cases occur in people above the age of 55. Dysphagia, weight loss and age over 55 are significant predictors of cancer. All patients presenting with dyspepsia and either alarm features or known conditions that increase the risk of gastric cancer should be referred for urgent endoscopy. Given that the majority of gastric 0032-6518 cancer cases occur in people over 55, urgent endoscopy is also recommended in this group with new uncomplicated dyspepsia prior to treatment, even without alarm symptoms or if the symptoms respond to treatment. Upper GI endoscopy with biopsy is the recommended investigation to confirm gastric cancer. Patients deemed medically fit should undergo surgical resection to cure early gastric cancer and chemotherapy followed by surgical resection for higher stage tumours. More than half of all patients with gastric cancer present with incurable advanced disease; palliative chemotherapy has a small but significant effect on survival.

RESUMEN

BACKGROUND: The updated Shape of Training curriculum has shortened the duration of specialty training. We present the potential role of out of programme clinical fellowships. METHOD: An electronic online survey was sent to all current fellows to understand their experiences, training opportunities and motivations.Data were collected on fellows' endoscopic experiences and publications using PubMed for all previous doctors who have completed the Sheffield Fellowship Programme. RESULTS: Since 2004, 39 doctors have completed the Sheffield Fellowship.Endoscopic experience: current fellows completed a median average of 350 (IQR 150-500) gastroscopies and 150 (IQR 106-251) colonoscopies per year. Fellows with special interests completed either 428 hepato-pancreato-biliary procedures or 70 endoscopic mucosal resections per year.Medline publications: Median average 9 publications(IQR 4-17). They have also received multiple national or international awards and 91% achieved a doctoral degree.The seven current fellows in the new Shape of Training era (57% male, 29% Caucasian, aged 31-40 years) report high levels of enjoyment due to their research projects, supervisory teams and social aspects. The most cited reasons for undertaking the fellowship were to develop a subspecialty interest, take time off the on-call rota and develop endoscopic skills. The most reported drawback was a reduced income.All current fellows feel that the fellowship has enhanced their clinical confidence and prepared them to become consultants. CONCLUSION: Out of programme clinical fellowships offer the opportunity to develop the required training competencies, subspecialty expertise and research skills in a supportive environment.
