RESUMO
BACKGROUND AND AIMS: Primary care providers (PCPs) play a critical role in colon cancer screening by initiating referrals to gastroenterologists for colonoscopy, but little is known about their role in pre-colonoscopy bowel preparation selection and pre-colonoscopy follow-up care. This study aimed to better understand coordination of care between PCPs and gastroenterologists as well as the current availability of "open-access" screening colonoscopy. METHODS: A multiple-choice survey was developed to assess PCPs' experiences with open-access colonoscopy, their involvement in the pre-colonoscopy process, and follow-up after colonoscopy. The survey was distributed electronically to a nationally representative sample of PCPs, via the American College of Physicians (ACP) Research Center's Internal Medicine Insider Research Panel. RESULTS: Of 442 PCPs invited to participate, 210 responded (response rate, 210/442, 48%), and 29 were ineligible (spent <25% of their time on clinical care or placed no referrals to colonoscopy), yielding 181 completed surveys. A total of 39% reported that open access was "rarely" or "never" available in their practice setting. The majority reported that pre-colonoscopy care was coordinated by gastroenterologists rather than PCPs. For example, 93% reported that gastroenterologists were responsible for bowel preparation selection in their practice setting. Post-colonoscopy, 54% of PCPs reported that they were responsible for ordering subsequent colonoscopies. CONCLUSIONS: PCPs frequently coordinate follow-up care postprocedure but play a relatively minor role in the pre-colonoscopy bowel preparation process. Open access availability for screening colonoscopy remains limited in this national sample of PCPs.

OBJECTIVES: Eluxadoline is a mixed µ-opioid receptor (OR) and κ-OR agonist and δ-OR antagonist, approved for the treatment of irritable bowel syndrome with diarrhea (IBS-D). This analysis evaluated the safety and tolerability of eluxadoline 75 and 100 mg twice daily (BID) in one Phase 2 (IBS-2001) and two Phase 3 (IBS-3001 and IBS-3002) studies. METHODS: Adults with IBS-D (Rome III criteria) were randomized to placebo or eluxadoline (75 or 100 mg) BID for 12 (IBS-2001), 26 (IBS-3002), or 52 (IBS-3001) weeks. Safety data were pooled. Adverse events (AEs) were assessed, with special focus on opioid-related AEs, including suspected sphincter of Oddi spasm (SOS) events. RESULTS: 2,776 patients were included in the enrolled set; the safety set comprised 2,814 patients, based on actual treatments received. The most frequent AEs in the placebo and eluxadoline 75 and 100 mg groups were constipation (2.5, 7.4, and 8.1%, respectively) and nausea (5.0, 8.1, and 7.1%, respectively); discontinuation due to constipation was uncommon (0.3, 1.1, and 1.5%, respectively). Ten SOS events (10/1,839; 0.5%) occurred in eluxadoline-treated patients, manifesting as acute abdominal pain with elevated aminotransferases or lipase, or pancreatitis; all occurred in patients without a gallbladder. Eight of these events occurred with the higher dose of eluxadoline, within 1 week of initiation of therapy, and all resolved with eluxadoline discontinuation. There were five events independently adjudicated as pancreatitis not associated with SOS, three of which were associated with heavy alcohol use. CONCLUSIONS: Eluxadoline was well tolerated in Phase 2 and 3 trials, with constipation and nausea the most common AEs. Consistent with the known adverse effects of opioid agonists, clinically apparent SOS events were observed in eluxadoline-treated patients. All occurred in patients without a gallbladder and the majority were observed in patients on the higher dose of eluxadoline, suggesting a possible association.

BACKGROUND: Adenoma detection rate (ADR) and sessile serrated polyp detection rate (SSPDR) data in surveillance colonoscopy are limited. AIMS: Our aim was to determine surveillance ADR and SSPDR and identify associated predictors. METHODS: A retrospective review of subjects who underwent surveillance colonoscopy for adenoma and/or SSP at an academic center was performed. The following exclusion criteria were applied: prior colonoscopy ≤ 3 years, incomplete examination, or another indication for colonoscopy. Patient, endoscopist, and procedure characteristics were collected. Predictors were identified using multivariable logistic regression. RESULTS: Of 3807 colonoscopies, 2416 met inclusion criteria. Surveillance ADR was 49% and, SSPDR was 8%. Higher ADR was associated with: age per year (OR 1.03; 95% CI 1.02-1.04), male gender (OR 1.55; 95% CI 1.29-1.88), BMI per kg/m2 (OR 1.02; 95% CI 1.01-1.04), withdrawal time per minute (OR 1.09; 95% CI 1.07-1.10), and endoscopists' screening ADR (OR 1.01; 95% CI 1.00-1.03). Years since training (OR 0.99; 95% CI 0.98-0.99) was associated with lower ADR. Family history of CRC (OR 1.58; 95% CI 1.02-2.27) and endoscopists' screening ADR (OR 1.40; 95% CI 1.15-1.74) were associated with higher SSPDR. African-American race (OR 0.36; 95% CI 0.10-0.75) and diabetes (OR 0.41; 95% CI 0.21-0.76) were associated with lower SSPDR. CONCLUSIONS: For surveillance colonoscopy, nearly half of patients had an adenoma and one in twelve had an SSP. In addition to established factors, BMI, endoscopists' screening ADR, and years since training were associated with ADR, whereas African-American race and diabetes were inversely associated with SSPDR. Further studies are needed prior to integrating surveillance ADR and SSPDR into quality metrics.

BACKGROUND: Comparative effectiveness data pertaining to competing colorectal cancer (CRC) screening tests do not exist but are necessary to guide clinical decision making and policy. OBJECTIVE: To perform a comparative synthesis of clinical outcomes studies evaluating the effects of competing tests on CRC-related mortality. DESIGN: Traditional and network meta-analyses. Two reviewers identified studies evaluating the effect of guaiac-based fecal occult blood testing (gFOBT), flexible sigmoidoscopy (FS), or colonoscopy on CRC-related mortality. INTERVENTIONS: gFOBT, FS, colonoscopy. MAIN OUTCOME MEASUREMENTS: Traditional meta-analysis was performed to produce pooled estimates of the effect of each modality on CRC mortality. Bayesian network meta-analysis (NMA) was performed to indirectly compare the effectiveness of screening modalities. Multiple sensitivity analyses were performed. RESULTS: Traditional meta-analysis revealed that, compared with no intervention, colonoscopy reduced CRC-related mortality by 57% (relative risk [RR] 0.43; 95% confidence interval [CI], 0.33-0.58), whereas FS reduced CRC-related mortality by 40% (RR 0.60; 95% CI, 0.45-0.78), and gFOBT reduced CRC-related mortality by 18% (RR 0.82; 95% CI, 0.76-0.88). NMA demonstrated nonsignificant trends favoring colonoscopy over FS (RR 0.71; 95% CI, 0.45-1.11) and FS over gFOBT (RR 0.74; 95% CI, 0.51-1.09) for reducing CRC-related deaths. NMA-based simulations, however, revealed that colonoscopy has a 94% probability of being the most effective test for reducing CRC mortality and a 99% probability of being most effective when the analysis is restricted to screening studies. LIMITATIONS: Randomized trials and observational studies were combined within the same analysis. CONCLUSION: Clinical outcomes studies demonstrate that gFOBT, FS, and colonoscopy are all effective in reducing CRC-related mortality. Network meta-analysis suggests that colonoscopy is the most effective test.

OBJECTIVES: There has been no definitive synthesis of the evidence for any benefit of available pharmacological therapies in opioid-induced constipation (OIC). We conducted a systematic review and meta-analysis to address this deficit. METHODS: We searched MEDLINE, EMBASE, EMBASE Classic, and the Cochrane central register of controlled trials through to December 2012 to identify placebo-controlled trials of µ-opioid receptor antagonists, prucalopride, lubiprostone, and linaclotide in the treatment of adults with OIC. No minimum duration of therapy was required. Trials had to report a dichotomous assessment of overall response to therapy, and data were pooled using a random effects model. Effect of pharmacological therapies was reported as relative risk (RR) of failure to respond to therapy, with 95% confidence intervals (CIs). RESULTS: Fourteen eligible randomized controlled trials (RCTs) of µ-opioid receptor antagonists, containing 4,101 patients, were identified. These were superior to placebo for the treatment of OIC (RR of failure to respond to therapy=0.69; 95% CI 0.63-0.75). Methylnaltrexone (six RCTs, 1,610 patients, RR=0.66; 95% CI 0.54-0.84), naloxone (four trials, 798 patients, RR=0.64; 95% CI 0.56-0.72), and alvimopan (four RCTs, 1,693 patients, RR=0.71; 95% CI 0.65-0.78) were all superior to placebo. Total numbers of adverse events, diarrhea, and abdominal pain were significantly commoner when data from all RCTs were pooled. Reversal of analgesia did not occur more frequently with active therapy. Only one trial of prucalopride was identified, with a nonsignificant trend toward higher responder rates with active therapy. Two RCTs of lubiprostone were found, with significantly higher responder rates with lubiprostone in both, but reporting of data precluded meta-analysis. CONCLUSIONS: µ-Opioid receptor antagonists are safe and effective for the treatment of OIC. More data are required before the role of prucalopride or lubiprostone in the treatment of OIC are clear.

OBJECTIVES: In 2006, the American College of Gastroenterology (ACG)/the American Society for Gastrointestinal Endoscopy (ASGE) Taskforce on Quality in Endoscopy published quality indicators for the major gastrointestinal procedures. Our primary aim was to use the published literature to assess current endoscopic retrograde cholangiopancreatography (ERCP) intraprocedural performance and compare it to the targets set by the ACG/ASGE taskforce. Our secondary aim was to determine whether performance varies across different health-care settings (academic and community), study designs (prospective and retrospective), and trainee participation. METHODS: A PubMed and EMBASE literature search from 1/1/2006 to 2/1/2013 was conducted. Articles were selected based on title, abstract, full text, and reporting of success rates for the intraprocedural quality indicators. Success rates, represented as numerical proportions, were collected from each study. For each success rate, a standard error and a 95% confidence interval (CI) was calculated. A random-effects meta-analysis model was used to weight each study, and a cumulative, weighted success rate (or effect size) for each indicator was determined. Random-effects meta-regression was then used to examine the impact of study setting, design, and trainee involvement on each quality indicator. RESULTS: A total of 8,005 articles were initially retrieved. Following the application of predefined criteria, 52 articles remained. The cumulative, weighted bile duct cannulation success rate was 89.3% (95% CI 0.866-0.919); pancreatic duct cannulation was 85.0% (95% CI 0.813-0.886); precut utilization rate was 10.5% (95% CI 0.087-0.123); common bile duct stone extraction rate was 88.3% (95% CI 0.825-0.941); and the rate of successful biliary stenting below the common bile duct bifurcation was 97.5% (95% CI 0.967-0.984). Subgroup analysis with meta-regression showed no statistically significant differences between academic and community settings, prospective and retrospective study designs, and trainee participation on success across bile duct cannulation, precut utilization, and common bile duct stone extraction (insufficient observations/variance for pancreatic duct cannulation and biliary stent placement). CONCLUSIONS: ERCP intraprocedural quality is in good standing. On the basis of this analysis, the two targets that could be potentially revised are precut utilization and biliary stenting. This analysis was confined to the published literature and therefore, in general, reflects the ERCP performance of institutions, primarily academic, that are conducting clinical research. Thus, it is difficult to generalize this performance assessment to the broader ERCP community as a whole.

BACKGROUND: The impact of fair bowel preparation on endoscopists' recommendations and adenoma miss rates in average-risk patients undergoing colonoscopy is unknown. OBJECTIVE: To assess the impact of fair bowel preparation on endoscopists' interval colonoscopy recommendations and miss rates in colonoscopies performed within 3 years of the index colonoscopy in average-risk patients undergoing colorectal cancer screening. DESIGN: Retrospective chart review. SETTING: Tertiary-care center. PATIENTS: Average-risk patients undergoing index colonoscopy for colorectal cancer screening between 2004 and 2006. INTERVENTION: Colonoscopy. MAIN OUTCOME MEASUREMENTS: Endoscopists' interval recommendations, adenoma miss rates. RESULTS: A total of 16,251 colonoscopy records were reviewed over a 2-year period. Of these cases, 1943 colonoscopies were performed for the sole indication of average risk or screening. Of these, fair bowel preparation was reported in 619 patients (31.9%). A repeat colonoscopy within 5 years was recommended in 70.4% of patients. The follow-up colonoscopy compliance rate within 3 years was 55.9%. Adenoma detection rates at index and follow-up colonoscopy were 20.5% and 28.2%, respectively. Of the 39 patients with follow-up colonoscopy within 3 years, the overall adenoma miss rate was 28%. Of the patients with an adenoma identified on follow-up colonoscopy, 13.6% had normal colonoscopy results on index examination. LIMITATIONS: Retrospective design. CONCLUSION: Fair bowel preparation led to a deviation from national guidelines with early repeat colonoscopy follow-up recommendations in nearly 60% of average-risk patients with normal colonoscopy results. In patients who returned for repeat colonoscopy within 3 years, the overall adenoma miss rate was 28%. Further guidelines on timing for repeat colonoscopy for fair bowel preparation are needed.

The growing importance of colonoscopy in the prevention of colorectal cancer has stimulated an effort to identify and track quality indicators for this procedure. Several factors have been identified so far which are readily measurable and in many cases have been associated with improved patient outcomes. There is also ample evidence of variations in performance of this procedure. As a result, gathering data about quality indicators may play a vital role in the process of continuous quality improvement. Quality indicators for colonoscopy in colorectal cancer prevention are described along with the evidence that supports their use in benchmarking, quality reporting, and continuous quality improvement.
RESUMO
BACKGROUND: Randomized controlled trials (RCTs) have yielded varying estimates of the benefit of flexible sigmoidoscopy (FS) screening for colorectal cancer (CRC). Our objective was to more precisely estimate the effect of FS-based screening on the incidence and mortality of CRC by performing a meta-analysis of published RCTs. METHODS AND FINDINGS: Medline and Embase databases were searched for eligible articles published between 1966 and 28 May 2012. After screening 3,319 citations and 29 potentially relevant articles, two reviewers identified five RCTs evaluating the effect of FS screening on the incidence and mortality of CRC. The reviewers independently extracted relevant data; discrepancies were resolved by consensus. The quality of included studies was assessed using criteria set out by the Evidence-Based Gastroenterology Steering Group. Random effects meta-analysis was performed. The five RCTs meeting eligibility criteria were determined to be of high methodologic quality and enrolled 416,159 total subjects. Four European studies compared FS to no screening and one study from the United States compared FS to usual care. By intention to treat analysis, FS-based screening was associated with an 18% relative risk reduction in the incidence of CRC (0.82, 95% CI 0.73-0.91, p<0.001, number needed to screen [NNS] to prevent one case of CRC = 361), a 33% reduction in the incidence of left-sided CRC (RR 0.67, 95% CI 0.59-0.76, p<0.001, NNS = 332), and a 28% reduction in the mortality of CRC (relative risk [RR] 0.72, 95% CI 0.65-0.80, p<0.001, NNS = 850). The efficacy estimate, the amount of benefit for those who actually adhered to the recommended treatment, suggested that FS screening reduced CRC incidence by 32% (p<0.001), and CRC-related mortality by 50% (p<0.001). Limitations of this meta-analysis include heterogeneity in the design of the included trials, absence of studies from Africa, Asia, or South America, and lack of studies comparing FS with colonoscopy or stool-based testing. CONCLUSIONS: This meta-analysis of randomized controlled trials demonstrates that FS-based screening significantly reduces the incidence and mortality of colorectal cancer in average-risk patients.

BACKGROUND AND AIMS: Folate has been implicated as a potential aetiological factor for colorectal cancer. Previous research has not adequately exploited concentrations of folate in normal colonic mucosal biopsies to examine the issue. METHODS: Logistic regression models were used to estimate ORs and 95% CIs of adenoma according to the tissue concentration of folate using asymptomatic average-risk women (40-70 years) in a colorectal cancer screening study. Of the 1593 eligible women who were offered enrolment, 1483 (93%) participated. Colonoscopy was complete to the caecum in 98.7% (1463/1483) of the subjects, and normal colonic tissue biopsies were obtained from 813 (56%) of these, of whom 170 had at least one adenoma. RESULTS: A marginal reduction in risk for proximal adenomas (OR 0.56, 95% CI 0.29 to 1.09) but not distal adenomas (OR 1.01, 95% CI 0.43 to 2.37) was observed among women in the highest quintile of tissue folate concentration. A significant reduction in risk for advanced adenoma was observed for women in the highest quintile of tissue folate concentration (OR 0.24, 95% CI 0.06 to 0.93). Defining the outcome as proximal adenomatous and/or hyperplastic polyps, statistically significant inverse associations with tissue concentrations of folate were also observed (OR 0.54, 95% CI 0.31 to 0.95 for quintile 5 vs quintile 1). CONCLUSIONS: These findings are consistent with the hypothesis that folate status of colonic mucosa is an exposure that is aetiologically important in determining the risk of particular molecular subtypes of colorectal cancer.

BACKGROUND: Screening of high-risk patients for hepatocellular carcinoma (HCC) may result in early diagnosis and improved outcomes. Our aim was to assess gastroenterologists' knowledge of HCC management guidelines established by the American Association for the Study of Liver Diseases (AASLD) and usual clinical practice. METHODS: We surveyed gastroenterologists attending two gastroenterology board review courses regarding their knowledge of HCC screening guidelines and usual practice of screening for HCC. Practices were compared and adherence to the 2005 published HCC guidelines was assessed. RESULTS: The median age of gastroenterology attending physicians (n = 160) was 41 years, and 75% were men with a median of 11.5 years of practice. A total of 79% of respondents correctly identified the high-risk patients who qualify for HCC screening. Most gastroenterologists correctly identified the screening methods (88.5%) and screening interval (98%). Among those who knew guideline recommendations (i.e., correct identification and certainty of guideline recommendations), 100% reported that they followed the guideline recommendation in their own practices. Regarding the management of abnormal test, 31% of gastroenterologists did not identify that referral for liver transplantation is the recommended management strategy for small HCC in a Child B patient with cirrhosis. The number of years in clinical practice (p = 0.30) and involvement in a malpractice suit (p = 0.34) did not affect the practice patterns. CONCLUSIONS: Most gastroenterologists correctly identified the common high-risk scenarios, methods, and interval of HCC screening as recommended by AASLD. Gastroenterologists who knew the HCC guidelines applied them in their own practice. However, approximately one-quarter do not know the appropriate management of a positive result, thereby likely hampering the overall effectiveness of screening.

BACKGROUND: Eluxadoline, a United States Food and Drug Administration (FDA)-approved treatment for irritable bowel syndrome with diarrhea (IBS-D), underwent a change to its US prescribing information on 21 April 2017, contraindicating it in patients without a gallbladder due to increased risk of pancreatitis. This study aimed to elucidate the potential role of eluxadoline's label change on the number of reported spontaneous adverse events (AEs) of pancreatitis. METHODS: A pharmacovigilance database (Oracle Argus) was searched for eluxadoline use and spontaneously reported pancreatitis cases from 1 January 2016 to 30 June 2018. Pancreatitis cases were reported as a proportion of the total number of reported AE cases in the safety database. The FDA's adverse event reporting system (AERS) was also interrogated for cases of pancreatitis concomitantly reported with eluxadoline use. RESULTS: In patients who received eluxadoline, 273 reported cases of pancreatitis were recorded (total AEs n = 2191; 12.5%). When known, 28.2% of patients reporting pancreatitis had intact gallbladders (49/174). Eluxadoline was withdrawn in 97.5% of cases, with 87.1% of patients improving or recovered at time of reporting. Importantly, the reporting proportion of pancreatitis cases decreased from 14.4% to 8.9% post label change. Findings were supported by the AERS results, which demonstrated a decrease in reporting proportion from 21.2% to 12.8%. CONCLUSIONS: While cautious interpretation is warranted, post-marketing data indicate that the contraindication of eluxadoline in patients without a gallbladder led to reduced reported cases of pancreatitis, with no additional reports of moderately severe or severe cases. Eluxadoline is a safe and well-tolerated treatment option for IBS-D when used according to the label.
RESUMO
BACKGROUND & AIMS: The incidences of decompensated cirrhosis (defined by ascites, hepatic encephalopathy, or bleeding esophageal varices), hepatocellular carcinoma (HCC), and liver-related mortality among patients infected with hepatitis C virus (HCV) who achieve a sustained viral response (SVR), compared with patients who fail treatment (treatment failure), are unclear. We performed a meta-analysis to quantify the incidences of these outcomes. METHODS: This meta-analysis included observational cohort studies that followed HCV treatment failure patients; data were collected regarding the incidence of decompensated cirrhosis, HCC, or liver-related mortality and stratified by SVR status. Two investigators independently extracted data on patient populations, study methods, and results by using standardized forms. The agreement between investigators in data extraction was greater than 95%. Data analysis was performed separately for studies that enrolled only HCV patients with advanced fibrosis. RESULTS: We identified 26 appropriate studies for meta-analysis. Among treatment failure patients with advanced fibrosis, rates of liver-related mortality (2.73%/year; 95% confidence interval [CI], 1.38-4.080), HCC (3.22%/year, 95% CI, 2.02-4.42), and hepatic decompensation (2.92%/year; 95% CI, 1.61-4.22) were substantial. Patients with SVR are significantly less likely than patients who experienced treatment failure to develop liver-related mortality (relative risk [RR], 0.23; 95% CI, 0.10-0.52), HCC (RR, 0.21; 95% CI, 0.16-0.27), or hepatic decompensation (RR, 0.16; 95% CI, 0.04-0.59). CONCLUSIONS: HCV patients with advanced fibrosis who do not undergo an SVR have substantial liver-related morbidity and mortality. Achieving SVR is associated with substantially lower liver-related morbidity and mortality.
