Early Esophageal Cancer: A Gastroenterologist's Disease.

Traditionally, early esophageal cancer (i.e., cancer limited to the mucosa or superficial submucosa) was managed surgically; the gastroenterologist's role was primarily to diagnose the tumor. Over the last decade, advances in endoscopic imaging, ablation, and resection techniques have resulted in a paradigm shift-diagnosis, staging, treatment, and surveillance are within the endoscopist's domain. Yet, there are few reviews that provide a focused, evidence-based approach to early esophageal cancer, and highlight areas of controversy for practicing gastroenterologists. In this manuscript, we will discuss the following: (1) utility of novel endoscopic technologies to identify high-grade dysplasia and early esophageal cancer, (2) role of endoscopic resection and imaging to stage early esophageal cancer, (3) endoscopic therapies for early esophageal cancer, and (4) indications for surgical and multidisciplinary management.

Survey Study on the Practice Patterns of the Evaluation and Management of Incidental Pancreatic Cysts.

BACKGROUND AND AIMS: Various gastrointestinal societies have released guidelines on the evaluation of asymptomatic pancreatic cysts (PCs). These guidelines differ on several aspects, which create a conundrum for clinicians. The aim of this study was to evaluate preferences and practice patterns in the management of incidental PCs in light of these societal recommendations. METHODS: An electronic survey distributed to members of the American Society for Gastrointestinal Endoscopy (ASGE). Main outcomes included practice setting (academic vs. community), preferences for evaluation, management, and surveillance strategies for PCs. RESULTS: A total of 172 subjects completed the study (52% academic-based endoscopists). Eighty-six (50%) and 138 (80%) of the participants responded that they would recommend EUS surveillance of incidental PCs measuring less than 2 cm and 3 cm, respectively. Nearly half of the endosonographers (42.5% community and 44% academic; p = 1.0) would routinely perform FNA on PCs without any high-risk features. More academic-based endoscopists (57% academic vs. 32% community; p = 0.001) would continue incidental PC surveillance indefinitely. CONCLUSIONS: There is significant variability in the approach of incidental PCs among clinicians, with practice patterns often diverging from the various GI societal guideline recommendations. Most survey respondents would routinely recommend EUS-FNA and indefinite surveillance for incidental PCs without high-risk features. The indiscriminate use of EUS-FNA and indefinite surveillance of all incidental PCs is not cost-effective, exposes the patient to unnecessary testing, and can further perpetuate diagnostic uncertainty. Well-designed studies are needed to improve our diagnostic and risk stratification accuracy in order to formulate a consensus on the management of these incidental PCs.

The use of human albumin in patients with cirrhosis: a European survey.

BACKGROUND: The administration of human albumin (HA) in patients with decompensated cirrhosis is still debated. The European Foundation for the Study of Chronic Liver Failure (EF-CLIF) promoted an online survey to assess its use across Europe. METHODS: Hepatologists were invited to participate to an electronic questionnaire based on multiple-choice questions divided in 6 different areas. A descriptive statistical analysis was performed to analyze the responses. RESULTS: One hundred-one hepatologists (36% non-EF-CLIF member), belonging to 86 centers (25% non-academic hospitals) completed the survey. The vast majority of participants prescribe HA for the evidence-based indications supported by international guidelines, while a proportion of them consider HA administration useful for other complications currently not supported by solid scientific evidence. Participants show a good level of knowledge about the non-oncotic properties of the molecule, while HA prescription does not appear to be restricted by health authorities in most centers, at least for the evidence-based indications. CONCLUSIONS: The present survey indicates that hepatologists across Europe present adherence to international guidelines and highlights the areas where solid scientific data are awaited to achieve a more appropriate HA prescription in patients with decompensated cirrhosis.

Assessment of the spectrum of hepatic encephalopathy: A multicenter study.

Hepatic encephalopathy (HE) is a major cause of morbidity in cirrhosis. However, its severity assessment is often subjective, which needs to be studied systematically. The aim was to determine how accurately trainee and nontrainee practitioners grade and manage HE patients throughout its severity. We performed a survey study using standardized simulated patient videos at 4 US and 3 Canadian centers. Participants were trainees (gastroenterology/hepatology fellows) and nontrainees (faculty, nurse practitioners, physician assistants). We determined the accuracy of HE severity identification and management options between grades <2 or ≥2 HE and trainees/nontrainees. In total, 108 respondents (62 trainees, 46 nontrainees) were included. For patients with grades <2 versus ≥2 HE, a higher percentage of respondents were better at correctly diagnosing grades ≥2 compared with grades <2 (91% versus 64%; P < 0.001). Specialized cognitive testing was checked significantly more often in grades <2, whereas more aggressive investigation for precipitating factors was ordered in HE grades >2. Serum ammonia levels were ordered in almost a third of grade ≥2 patients. For trainees and nontrainees, HE grades were identified similarly between groups. Trainees were less likely to order serum ammonia and low-protein diets, more likely to order rifaximin, and more likely to perform a more thorough workup for precipitating factors compared with nontrainee respondents. There was excellent concordance in the classification of grade ≥2 HE between nontrainees versus trainees, but lower grades showed discordance. Important differences were seen regarding blood ammonia, specialized testing, and nutritional management between trainees and nontrainees. These results have important implications at the patient level, interpreting multicenter clinical trials, and in the education of practitioners. Liver Transplantation 24 587-594 2018 AASLD.

Albumin Use in Patients With Cirrhosis in France: Results of the "ALBU-LIVE" Survey: A Case for Better EASL Guidelines Diffusion and/or Revision.

INTRODUCTION: The use of human albumin for the management of cirrhosis has increased. Recommendations have been published for therapeutic paracentesis (TP), spontaneous bacterial peritonitis (SBP), and type 1 hepatorenal syndrome (HRS). The goal of this survey was to assess the prescription practices of French hepatogastroenterologists. METHODS: All hepatogastroenterologists were contacted. The questionnaire evaluated (1) the use of albumin in validated indications and (2) the prescription of albumin for nonvalidated clinical situations. RESULTS: Responses were analyzed from 451 (50.1%) practitioners. The mean age was 40 years (range, 24 to 67 y). Physicians practiced in a university hospital (47.7%) or a general hospital (45.8%). There were 56.7% senior practitioners. Overall 99.6% of the practitioners compensated for TP. Albumin was used by 87.8% of the physicians, with a fixed dose being used by 84.6%. For SBP, 94% of the physicians used albumin concomitantly with antibiotics. The recommended protocol was followed by 56.2% of the practitioners: more often by senior university hospital practitioners than by senior general hospital practitioners (P=0.015). About 66.5% used albumin infusion for the diagnosis of HRS: used more often by senior university hospital practitioners (P=0.0006). Albumin was used concomitantly with vasopressor treatment by 84%; the dose and the duration varied considerably. About 23.5% used albumin for severe bacterial infection, 47.9% for severe hyponatremia, 43.9% for severe hypoalbuminemia, and 65.9% for hydrothorax. CONCLUSIONS: In this large French survey, albumin is only prescribed in accordance with recommendations for TP. The schedule for SBP is followed by only 56% of the practitioners. The use of albumin for HRS is not adapted to recommendations, which are not well known, suggesting that they should be more diffused.

Diagnosis and treatment in chronic pancreatitis: an international survey and case vignette study.

BACKGROUND: The aim of the study was to evaluate the current opinion and clinical decision-making process of international pancreatologists, and to systematically identify key study questions regarding the diagnosis and treatment of chronic pancreatitis (CP) for future research. METHODS: An online survey, including questions regarding the diagnosis and treatment of CP and several controversial clinical case vignettes, was send by e-mail to members of various international pancreatic associations: IHPBA, APA, EPC, ESGE and DPSG. RESULTS: A total of 288 pancreatologists, 56% surgeons and 44% gastroenterologists, from at least 47 countries, participated in the survey. About half (48%) of the specialists used a classification tool for the diagnosis of CP, including the Mayo Clinic (28%), Mannheim (25%), or Büchler (25%) tools. Overall, CT was the preferred imaging modality for evaluation of an enlarged pancreatic head (59%), pseudocyst (55%), calcifications (75%), and peripancreatic fat infiltration (68%). MRI was preferred for assessment of main pancreatic duct (MPD) abnormalities (60%). Total pancreatectomy with auto-islet transplantation was the preferred treatment in patients with parenchymal calcifications without MPD abnormalities and in patients with refractory pain despite maximal medical, endoscopic, and surgical treatment. In patients with an enlarged pancreatic head, 58% preferred initial surgery (PPPD) versus 42% initial endoscopy. In patients with a dilated MPD and intraductal stones 56% preferred initial endoscopic ± ESWL treatment and 29% preferred initial surgical treatment. CONCLUSION: Worldwide, clinical decision-making in CP is largely based on local expertise, beliefs and disbeliefs. Further development of evidence-based guidelines based on well designed (randomized) studies is strongly encouraged.

Predictors of Use of Monitored Anesthesia Care for Outpatient Gastrointestinal Endoscopy in a Capitated Payment System.

BACKGROUND & AIMS: Use of monitored anesthesia care (MAC) for gastrointestinal endoscopy has increased in the Veterans Health Administration (VHA) as in fee-for-service environments, despite the absence of financial incentives. We investigated factors associated with use of MAC in an integrated health care delivery system with a capitated payment model. METHODS: We performed a retrospective cohort study using multilevel logistic regression, with MAC use modeled as a function of procedure year, patient- and provider-level factors, and facility effects. We collected data from 2,091,590 veterans who underwent outpatient esophagogastroduodenoscopy and/or colonoscopy during fiscal years 2000-2013 at 133 facilities. RESULTS: The adjusted rate of MAC use in the VHA increased 17% per year (odds ratio for increase, 1.17; 95% confidence interval, 1.09-1.27) from fiscal year 2000 through 2013. The most rapid increase occurred starting in 2011. VHA use of MAC was associated with patient-level factors that included obesity, obstructive sleep apnea, higher comorbidity, and use of prescription opioids and/or benzodiazepines, although the magnitude of these effects was small. Provider-level and facility factors were also associated with use of MAC, although again the magnitude of these associations was small. Unmeasured facility-level effects had the greatest effect on the trend of MAC use. CONCLUSIONS: In a retrospective study of veterans who underwent outpatient esophagogastroduodenoscopy and/or colonoscopy from fiscal year 2000 through 2013, we found that even in a capitated system, patient factors are only weakly associated with use of MAC. Facility-level effects are the most prominent factor influencing increasing use of MAC. Future studies should focus on better defining the role of MAC and facility and organizational factors that affect choice of endoscopic sedation. It will also be important to align resources and incentives to promote appropriate allocation of MAC based on clinically meaningful patient factors.

Transition of early-phase treatment for acute pancreatitis: An analysis of nationwide epidemiological survey.

Treatment of acute pancreatitis (AP) is one of the critical challenges to the field of gastroenterology because of its high mortality rate and high medical costs associated with the treatment of severe cases. Early-phase treatments for AP have been optimized in Japan, and clinical guidelines have been provided. However, changes in early-phase treatments and the relationship between treatment strategy and clinical outcome remain unclear. Retrospective analysis of nationwide epidemiological data shows that time for AP diagnosis has shortened, and the amount of initial fluid resuscitation has increased over time, indicating the compliance with guidelines. In contrast, prophylactic use of broad-spectrum antibiotics has emerged. Despite the potential benefits of early enteral nutrition, its use is still limited. The roles of continuous regional arterial infusion in the improvement of prognosis and the prevention of late complications are uncertain. Furthermore, early-phase treatments have had little impact on late-phase complications, such as walled-off necrosis, surgery requirements and late (> 4 w) AP-related death. Based on these observations, early-phase treatments for AP in Japan have approached the optimal level, but late-phase complications have become concerning issues. Early-phase treatments and the therapeutic strategy for late-phase complications both need to be optimized based on firm clinical evidence and cost-effectiveness.

Combination of corticosteroids and 5-aminosalicylates or corticosteroids alone for patients with moderate-severe active ulcerative colitis: A global survey of physicians' practice.

AIM: To examine treatment decisions of gastroenterologists regarding the choice of prescribing 5-aminosalycilates (5ASA) with corticosteroids (CS) versus corticosteroids alone for patients with active ulcerative colitis (UC). METHODS: A cross-sectional questionnaire exploring physicians' attitude toward 5ASA + CS combination therapy vs CS alone was developed and validated. The questionnaire was distributed to gastroenterology experts in twelve countries in five continents. Respondents' agreement with stated treatment choices were assessed by standardized Likert scale. Background professional characteristics of respondents were analyzed for correlation with responses. RESULTS: Six hundred and sixty-four questionnaires were distributed and 349 received (52.6% response rate). Of 340 eligible respondents, 221 (65%) would continue 5ASA in a patient hospitalized for intravenous CS treatment due to a moderate-severe UC flare, while 108 (32%) would stop the 5ASA (P < 0.001), and 11 (3%) are undecided. Similarly, 62% would continue 5ASA in an out-patient starting oral CS. However, only 140/340 (41%) would proactively start 5ASA in a hospitalized patient not receiving 5ASA before admission. Most (94%) physicians consider the safety profile of 5ASA as very good. Only 52% consider them inexpensive, 35% perceive them to be expensive and 12% are undecided. On multi-variable analysis, less years of practice and perception of a plausible additive mechanistic effect of 5ASA + CS were positively associated with the decision to continue 5ASA with CS. CONCLUSION: Despite the absence of data supporting its benefit, most gastroenterologists endorse combination of 5ASA + CS for patients with active moderate-to-severe UC. Randomized controlled trials are needed to assess if 5ASA confer any benefit for these patients.

Association of Provider Specialty and Multidisciplinary Care With Hepatocellular Carcinoma Treatment and Mortality.

BACKGROUND & AIMS: Little is known about provider and health system factors that affect receipt of active therapy and outcomes of patients with hepatocellular carcinoma (HCC). We investigated patient, provider, and health system factors associated with receipt of active HCC therapy and overall survival. METHODS: We performed a national, retrospective cohort study of all patients diagnosed with HCC from January 1, 2008 through December 31, 2010 (n = 3988) and followed through December 31 2014 who received care through the Veterans Administration (128 centers). Outcomes were receipt of active HCC therapy (liver transplantation, resection, local ablation, transarterial therapy, or sorafenib) and overall survival. RESULTS: In adjusted analyses, receiving care at an academically affiliated Veterans Administration hospital (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.60-2.41) or a multi-specialist evaluation (OR, 1.60; 95% CI, 1.15-2.21), but not review by a multidisciplinary tumor board (OR, 1.19; 95% CI, 0.98-1.46), was associated with a higher likelihood of receiving active HCC therapy. In time-varying Cox proportional hazards models, liver transplantation (hazard ratio [HR], 0.22; 95% CI, 0.16-0.31), liver resection (HR, 0.38; 95% CI, 0.28-0.52), ablative therapy (HR, 0.63; 95% CI, 0.52-0.76), and transarterial therapy (HR, 0.83; 95% CI, 0.74-0.92) were associated with reduced mortality. Subspecialist care by hepatologists (HR, 0.70; 95% CI, 0.63-0.78), medical oncologists (HR, 0.82; 95% CI, 0.74-0.91), or surgeons (HR, 0.79; 95% CI, 0.71-0.89) within 30 days of HCC diagnosis, and review by a multidisciplinary tumor board (HR, 0.83; 95% CI, 0.77-0.90), were associated with reduced mortality. CONCLUSIONS: In a retrospective cohort study of almost 4000 patients with HCC cared for at VA centers, geographic, provider, and system differences in receipt of active HCC therapy are associated with patient survival. Multidisciplinary methods of care delivery for HCC should be prospectively evaluated and standardized to improve access to HCC therapy and optimize outcomes.

Factors Associated With Shorter Colonoscopy Surveillance Intervals for Patients With Low-Risk Colorectal Adenomas and Effects on Outcome.

BACKGROUND & AIMS: Endoscopists do not routinely follow guidelines to survey individuals with low-risk adenomas (LRAs; 1-2 small tubular adenomas, < 1 cm) every 5-10 years for colorectal cancer; many recommend shorter surveillance intervals for these individuals. We aimed to identify the reasons that endoscopists recommend shorter surveillance intervals for some individuals with LRAs and determine whether timing affects outcomes at follow-up examinations. METHODS: We collected data from 1560 individuals (45-75 years old) who participated in a prospective chemoprevention trial (of vitamin D and calcium) from 2004 through 2008. Participants in the trial had at least 1 adenoma, detected at their index colonoscopy, and were recommended to receive follow-up colonoscopy examinations at 3 or 5 years after adenoma identification, as recommended by the endoscopist. For this analysis we collected data from only participants with LRAs. These data included characteristics of participants and endoscopists and findings from index and follow-up colonoscopies. Primary endpoints were frequency of recommending shorter (3-year) vs longer (5-year) surveillance intervals, factors associated with these recommendations, and effect on outcome, determined at the follow-up colonoscopy. RESULTS: A 3-year surveillance interval was recommended for 594 of the subjects (38.1%). Factors most significantly associated with recommendation of 3-year vs a 5-year surveillance interval included African American race (relative risk [RR] to white, 1.41; 95% confidence interval [CI], 1.14-1.75), Asian/Pacific Islander ethnicity (RR to white, 1.7; 95% CI, 1.22-2.43), detection of 2 adenomas at the index examination (RR vs 1 adenoma, 1.47; 95% CI, 1.27-1.71), more than 3 serrated polyps at the index examination (RR=2.16, 95% CI, 1.59-2.93), or index examination with fair or poor quality bowel preparation (RR vs excellent quality, 2.16; 95% CI, 1.66-2.83). Other factors that had a significant association with recommendation for a 3-year surveillance interval included family history of colorectal cancer and detection of 1-2 serrated polyps at the index examination. In comparisons of outcomes, we found no significant differences between the 3-year vs 5-year recommendation groups in proportions of subjects found to have 1 or more adenomas (38.8% vs 41.7% respectively; P = .27), advanced adenomas (7.7% vs 8.2%; P = .73) or clinically significant serrated polyps (10.0% vs 10.3%; P = .82) at the follow-up colonoscopy. CONCLUSIONS: Possibly influenced by patients' family history, race, quality of bowel preparation, or number or size of polyps, endoscopists frequently recommend 3-year surveillance intervals instead of guideline-recommended intervals of 5 years or longer for individuals with LRAs. However, at the follow-up colonoscopy, similar proportions of participants have 1 or more adenomas, advanced adenomas, or serrated polyps. These findings support the current guideline recommendations of performing follow-up examinations of individuals with LRAs at least 5 years after the index colonoscopy.

Enteral Access Procedures: An 18-Year Analysis of Changing Patterns of Utilization in the Medicare Population.

PURPOSE: To evaluate national trends in enteral access and maintenance procedures for Medicare beneficiaries with regard to utilization rates, specialty group roles, and sites of service. MATERIALS AND METHODS: Using Medicare Physician Supplier Procedure Summary Master Files for the period 1994-2012, claims for gastrostomy and gastrojejunostomy access and maintenance procedures were identified. Longitudinal utilization rates were calculated using annual enrollment data. Procedure volumes by site of service and medical specialty were analyzed. RESULTS: Between 1994 and 2012, de novo enteral access procedure utilization decreased from 61.6 to 42.3 per 10,000 Medicare Part B beneficiaries (-31%). Gastroenterologists and surgeons performed > 80% of procedures (unchanged over study period) with 97% in the hospital setting. Over time, relative use of an endoscopic approach (62% in 1994; 82% in 2012) increased as percutaneous (21% to 12%) and open surgical (17% to 5%) procedures declined. Existing enteral access maintenance services increased 29% (from 20.1 to 25.9 per 10,000 beneficiaries). Radiologists (from 13% to 31%) surpassed gastroenterologists (from 36% to 21%) as dominant providers of maintenance procedures. Emergency physicians (from 8% to 23%) and nonphysician providers (from 0% to 6%) have seen rapid growth as maintenance services providers as these services have transitioned increasingly to the emergency department setting (from 18% to 32%). CONCLUSIONS: Among Medicare beneficiaries, de novo enteral access procedures have declined in the last 2 decades as existing access maintenance services have increased. The latter are increasingly performed by radiologists, emergency physicians, and nonphysician providers.

Treatment Targets in Inflammatory Bowel Disease: Current Status in Daily Practice.

BACKGROUND AND AIMS: Recently, treatment goals in inflammatory bowel disease (IBD) in clinical trials have shifted from mainly symptom-based to more mucosa-driven. Real world data on treatment priorities are lacking. We aimed to investigate the current practice and most commonly used definitions of IBD treatment targets among Dutch gastroenterologists. METHODS: Dutch gastroenterologists were asked to participate in a computer-based nation-wide survey. We asked questions on demographics, opinion and current practice regarding IBD treatment targets. RESULTS: Twenty-four percent (134/556) of the respondents completed the survey. For both Crohn's disease (CD) (47.3%, 61/129) and ulcerative colitis (UC)(45%, 58/129) the main treatment goal was to achieve and maintain deep remission, defined as clinical, biochemical and endoscopic remission. Seventy-six percent of the participants use mucosal healing (MH) as a potential treatment target for IBD, whereas 22.6% use histological remission. There is no single definition for MH in IBD. The majority use Mayo score ≤ 1 in UC (52%) and 'macroscopic normal mucosa' in CD (66%). CONCLUSION: More stringent and mucosa-driven treatment targets as 'deep remission' and 'mucosal healing' have found traction in clinical practice. The most commonly used definition for MH in routine practice is endoscopic MAYO score

Real-life Perception and Practice Patterns of NAFLD/NASH in Romania: Results of a Survey Completed by 102 Board-certified Gastroenterologists.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) has an increasing incidence worldwide, reflecting the epidemics of obesity and metabolic syndrome. Data on knowledge, attitude and management by the Romanian gastroenterologists with regard to NAFLD are lacking. METHODS: We assessed current diagnostic and treatment patterns of the management of NAFLD among 102 Romanian board certified gastroenterologists using a survey developed to collect information regarding participants' clinical practice, diagnostic tools and usage of medication in patients with NAFLD. RESULTS: 71.6% of the surveyed gastroenterologists (SG) had more than 5 years of gastroenterology practice, were university affiliated and 37.3% had predominant activity in hepatology (>60%). In Romania, 60.8% of the SG would diagnose NAFLD only if all other causes of liver disease were absent. All practitioners use a noninvasive tool for staging NAFLD, 45.1% use both serum markers and transient elastography. Liver biopsy is performed by 61.8% of the SG in the presence of a discordant result in two noninvasive methods of fibrosis evaluation. The most frequently prescribed drugs are: silymarin (88.2%), vitamin E (78.4%) and ursodeoxycholic acid (77.4%). CONCLUSION: The results of this survey suggest that clinical practice patterns among Romanian gastroenterologists for the diagnosis (mainly liver biopsy) and management of NAFLD frequently diverge from published practice guidelines. Nonalcoholic steatohepatitis is probably underdiagnosed, especially in patients with normal transaminase levels and is also overtreated with drugs that are not recommended in the guidelines.

High variation in treatment strategies for gastrointestinal angiodysplasias.

OBJECTIVE: Angiodysplasias (ADs) are the second leading cause of gastrointestinal bleeding in the elderly. The impact extends from no symptoms to chronic anaemia. Treatment guidelines are lacking. The aim of this study was to assess the current practice of gastrointestinal ADs and explore possible new research areas. On the basis of existing evidence, we would like to propose a treatment algorithm. METHODS: We administered a 19-item web-based survey to gastroenterologists in the Netherlands between February and April of 2015. RESULTS: A total of 111 (response rate 28%) gastroenterologists completed the survey (mean age=47 years; 24% women). The respondents identified Von Willebrand disease (17%), chronic kidney disease (21%) and aortic stenosis (77%) as risk factors for the development of ADs. Colonoscopy (54%) and esophagogastroduodenoscopy (43%) were the preferred first tools to screen for ADs. The favoured (77%) first treatment option is endoscopic argon plasma coagulation, whereas 20% start iron supplementation or blood transfusions. Treatment strategy is mostly (65%) based on the location of the ADs. Small bowel ADs are considered the most difficult to treat, because of the need for balloon enteroscopy. Of the gastroenterologists, 13% would treat ADs as a coincident finding during endoscopy. Medical therapy is mostly started in refractory ADs, and thalidomide (40%) is preferred over octreotide (19%). Thalidomide is more preferred by gastroenterologists working in a teaching hospital. CONCLUSION: Identification of risk factors and treatment of ADs vary widely between gastroenterologists in the Netherlands. Further research is needed to create an evidence-based guideline and thereby optimize the management of symptomatic ADs.
