RESUMO

BACKGROUND AND AIM: Evidence on the impact of frailty in patients with upper gastrointestinal bleed (UGIB) is limited. This study aims to define the role of frailty as defined by Canadian Study of Health and Aging clinical frailty scale (CSHA-CFS) in predicting mortality in UGIB. METHODS: A prospective single-center cohort study was conducted over 21 months on all consecutive patients with UGIB. Data on demographics, lab parameters, Glasgow Blatchford score, CSHA-CFS, Charlson Comorbidity Index, and AIMS65 score was recorded. The primary outcome was all-cause inpatient mortality. The secondary outcomes were all-cause 30-day mortality, 30-day rebleeding, 30-day readmission, hospital length of stay (LoS), intensive care unit (ICU) admission, need for repeat endoscopy, and need for blood transfusion. The data were evaluated using univariate and multivariate analysis. RESULTS: There were 298 eligible patients, of which 63% were males, median age was 68 years, 44% were from non-English-speaking background, and 72% had major comorbidities. The all-cause inpatient and 30-day mortality were 9.4% and 10.7%, respectively. In the multivariate analysis, CHSA-CFS was the independent predictor of all-cause inpatient mortality (OR 1.66; 95% CI 1.13-2.143; P = 0.010) and all-cause 30-day mortality (OR 1.83; 95% CI 1.26-2.67; P = 0.002). CHSA-CFS was not a significant predictor of 30-day rebleed, 30-day readmission, ICU admission, hospital LoS, or need for blood transfusion. CONCLUSION: Frailty is an important independent predictor of mortality in patients with UGIB. Frailty assessment can guide clinical decision making and allow targeting of health-care resource (Australia/New Zealand Clinical Trial Registry number: ACTRN12622000821796).

RESUMO

BACKGROUND: Colorectal cancer (CRC) is a major health problem. There is minimal consensus of the appropriate approach to manage patients with positive immunochemical fecal occult blood test (iFOBT), following a recent colonoscopy. AIM: To determine the prevalence of advanced neoplasia in patients with a positive iFOBT after a recent colonoscopy, and clinical and endoscopic predictors for advanced neoplasia. METHODS: The study recruited iFOBT positive patients who underwent colonoscopy between July 2015 to March 2020. Data collected included demographics, clinical characteristics, previous and current colonoscopy findings. Primary outcome was the prevalence of CRC and advanced neoplasia in a patient with positive iFOBT and previous colonoscopy. Secondary outcomes included identifying any clinical and endoscopic predictors for advanced neoplasia. RESULTS: The study included 1051 patients (male 53.6%; median age 63). Forty-two (4.0%) patients were diagnosed with CRC, 513 (48.8%) with adenoma/sessile serrated lesion (A-SSL) and 257 (24.5%) with advanced A-SSL (AA-SSL). A previous colonoscopy had been performed in 319 (30.3%). In this cohort, four (1.3%) were diagnosed with CRC, 146 (45.8%) with A-SSL and 56 (17.6%) with AA-SSL. Among those who had a colonoscopy within 4 years, none had CRC and 7 had AA-SSL. Of the 732 patients with no prior colonoscopy, there were 38 CRCs (5.2%). Independent predictors for advanced neoplasia were male [odds ratio (OR) = 1.80; 95% confidence interval (CI): 1.35-2.40; P < 0.001), age (OR = 1.04; 95%CI: 1.02-1.06; P < 0.001) and no previous colonoscopy (OR = 2.07; 95%CI: 1.49-2.87; P < 0.001). CONCLUSION: A previous colonoscopy, irrespective of its result, was associated with low prevalence of advanced neoplasia, and if performed within four years of a positive iFOBT result, was protective against CRC.

RESUMO

BACKGROUND: Colonoscopy remains the gold standard for detection of colonic disease. An optimal evaluation depends on adequate bowel cleansing. Patients with inflammatory bowel disease (IBD), require frequent endoscopic assessment for both activity and dysplasia assessment. Two commonly used bowel preparations in Australia are Prep Kit-C (Pc) and Moviprep (Mp). Little is known about tolerability, efficacy and safety of split protocols of Mp and Pc in both IBD and non-IBD patients. AIM: To primary aim was to compare the tolerability, efficacy and safety of split protocols of Mp and Pc in patients having a colonoscopy. The secondary aim was to compare the efficacy, tolerability and safety of either preparation in patients with or without IBD. METHODS: Patients were randomized to Pc or Mp bowel preparation. Patients completed a questionnaire to assess tolerability. Efficacy was assessed using the Ottawa Bowel Preparation Score. Serum electrolytes and renal function were collected one week prior to colonoscopy and on the day of colonoscopy. RESULTS: Of 338 patients met the inclusion criteria. Of 168 patients randomized to Mp and 170 to Pc. The efficacy of bowel preparation (mean Ottawa Bowel Preparation Score) was similar between Mp (5.4 ± 2.4) and Pc (5.1 ± 2.1) (P = 0.3). Mean tolerability scores were similar in Mp (11.84 ± 5.4) and Pc (10.99 ± 5.2; P = 0.17). 125 patients had IBD (73 had Crohn's Disease and 52 had Ulcerative colitis). Sixty-four IBD patients were allocated to Mp and 61 to Pc. In non-IBD patients, 104 were allocated to Mp and 109 to Pc. The mean tolerability score in the IBD group was lower than the non-IBD group (mean tolerability scores: IBD: 10.3 ± 5.1 and non-IBD: 12.0 ± 5.3; P = 0.01). IBD patients described more abdominal pain with Mp when compared with Pc; (Mp: 5.7 ± 4.4 vs Pc: 3.6 ± 2.6, P = 0.046). Serum magnesium level increased with Pc compared with Mp in all patients (mean increase in mmol/L: Mp: 0.03 ± 0.117 and Pc: 0.11 ± 0.106; P < 0.0001). CONCLUSION: In this study, the efficacy, tolerability and safety of Mp and Pc were similar in all patients. However, patients with IBD reported lower tolerability with both preparations. Specifically, IBD patients had more abdominal pain with Mp. These results should be considered when recommending bowel preparation especially to IBD patients.

RESUMO

Background: There is controversy about the proactive clinical application of therapeutic drug monitoring (TDM) of biologic drugs in Crohn's disease (CD). One way to practically assess this is to examine how TDM influences management decisions. We examined how knowledge of proactive and reactive antitumor necrosis factor (anti-TNF) drug levels changes management in a variety of clinical scenarios. Methods: In this retrospective cohort study, all adults with CD having trough level infliximab or adalimumab measurements at Liverpool Hospital between June 2013 and July 2016 were included. Demographics, indications for testing, anti-TNF drug levels, and treatment details were collected along with subsequent management decisions. The decision made by the treating clinician after receiving the drug level was compared to a consensus decision from a panel of 3 gastroenterologists based on the clinical, laboratory, imaging, and/or endoscopic results without the drug level. When these 2 decisions were discrepant, the anti-TNF drug level was deemed to have changed management. Results: One hundred and eighty-seven trough levels of infliximab or adalimumab from 108 patients were analyzed. Overall, assessment of anti-TNF levels affected management in 46.9% of the instances. Knowledge of the drug level was also more likely to result in management change when the test was performed for reactive TDM compared to proactive TDM (63% vs 36%, P = .001). Conclusions: The addition of TDM of anti-TNF agents to routine investigations alters management decisions in adult CD patients on anti-TNF therapy in both proactive and reactive settings.

RESUMO

BACKGROUND: Dysplasia surveillance is recognized as an integral component in the management of inflammatory bowel diseases (IBDs). The adherence to surveillance guidelines is variable, and understanding of quality indicators and predictors of behavior is currently limited. OBJECTIVE: To perform a nationwide evaluation of the quality of IBD surveillance practiced by Australian endoscopists and to determine the predictors of quality practice. DESIGN: Cross-sectional nationwide survey. SETTING: Survey distributed through the gastroenterology and colorectal surgery societies covering knowledge and practice of IBD surveillance. MAIN OUTCOME MEASUREMENTS: Adherence to indicators of high-quality surveillance and median score of IBD surveillance guideline knowledge. RESULTS: A total of 264 responses were received, comprising 240 respondents who perform surveillance screening (218 gastroenterologists, 46 colorectal surgeons). Gastroenterologists were significantly more likely to undertake surveillance (P < .001), adhere to guidelines (P = .02), use advanced imaging modalities (P = .04), and have greater surveillance knowledge than colorectal surgeons (P < .001). Knowledge score and gastroenterologists were independent predictors of dysplasia screening (odds ratio [OR] 1.66; 95% confidence interval [CI], 1.41-1.96 and OR 11.2; 95% CI, 4.53-27.87), guideline adherence (OR 1.15; 95% CI, 1.01-1.31 and OR 2.42; 95% CI, 1.11-5.30), and advanced endoscopic imaging technique use (OR 1.19; 95% CI, 1.05-1.35 and OR 2.2; 95% CI, 1.02-4.74). LIMITATIONS: Potential responder bias results appear, however, aligned with those of previous studies. CONCLUSIONS: IBD dysplasia surveillance in Australia is being performed at a high standard. Gastroenterology specialization and knowledge score have been demonstrated to be strong predictors of high-quality surveillance practice. This is the first study to determine predictors of screening behavior and quantify surveillance quality. These results further emphasize that gastroenterologists should play a key role in IBD surveillance.

RESUMO

AIM: To examine the impact of the patient's birthplace on the prevalence of colonic polyps and histopathological subtypes. METHODS: This is a retrospective audit of the colonoscopy practice of one Gastroenterologist in a tertiary-referral hospital from 2008 to 2011. Data collected include demography, birthplace, language spoken, details of the colonoscopy including indications, completion rates, complications, results including prevalence and histopathology of polyps. Statistical methods used were binary logistic regression, χ(2) and Mann-Whitney U. RESULTS: A total of 623 patients (48% male, 67% aged over 50 years) were recruited and categorised according to birthplace: Australia/New Zealand 42%, European 20%, Asian 15%, Middle Eastern/African 11%, South American 9% and Pacific Islander 3%. The median age of the cohort was 56.3 years (range: 17-91 years), median body mass index 27.3 kg/m(2) (range: 16-51 kg/m(2)), 25% were smokers, 25% had hypercholesterolemia, 20% had diabetes mellitus 16% were on aspirin and 7% were on non-steroidal anti-inflammatory drugs. A total of 651 colonoscopies were performed for standard indications. The prevalence of polyps varied according to patient's birthplace: Europe 45.1%, Australia and New Zealand 39.5%, Pacific Islands 33.3%, Asia 30.3%, Middle East and Africa 26.9% and South America 24.5% (P = 0.027, df = 6). However, multivariate analysis revealed that birthplace was not an independent predictor of developing polyps, including adenomas and advanced adenomas after correcting for age and male sex. CONCLUSION: Birthplace is not a predictor for developing colorectal neoplasia, including adenomas and advanced adenomas; hence, should not influence the recommendations for colorectal cancer screening.

RESUMO

BACKGROUND: The rapid increase in the incidence of colorectal cancer (CRC) in the Asia-Pacific region in the past decade has resulted in recommendations to implement mass CRC screening programs. However, the knowledge of screening and population screening behaviors between countries is largely lacking. OBJECTIVE: This multicenter, international study investigated the association of screening test participation with knowledge of, attitudes toward, and barriers to CRC and screening tests in different cultural and sociopolitical contexts. METHODS: Person-to-person interviews by using a standardized survey instrument were conducted with subjects from 14 Asia-Pacific countries/regions to assess the prevailing screening participation rates, knowledge of and attitudes toward and barriers to CRC and screening tests, intent to participate, and cues to action. Independent predictors of the primary endpoint, screening participation was determined from subanalyses performed for high-, medium-, and low-participation countries. RESULTS: A total of 7915 subjects (49% male, 37.8% aged 50 years and older) were recruited. Of the respondents aged 50 years and older, 809 (27%) had undergone previous CRC testing; the Philippines (69%), Australia (48%), and Japan (38%) had the highest participation rates, whereas India (1.5%), Malaysia (3%), Indonesia (3%), Pakistan (7.5%), and Brunei (13.7%) had the lowest rates. Physician recommendation and knowledge of screening tests were significant predictors of CRC test uptake. In countries with low-test participation, lower perceived access barriers and higher perceived severity were independent predictors of participation. Respondents from low-participation countries had the least knowledge of symptoms, risk factors, and tests and reported the lowest physician recommendation rates. "Intent to undergo screening" and "perceived need for screening" was positively correlated in most countries; however, this was offset by financial and access barriers. LIMITATIONS: Ethnic heterogeneity may exist in each country that was not addressed. In addition, the participation tests and physician recommendation recalls were self-reported. CONCLUSIONS: In the Asia-Pacific region, considerable differences were evident in the participation of CRC tests, physician recommendations, and knowledge of, attitudes toward, and barriers to CRC screening. Physician recommendation was the uniform predictor of screening behavior in all countries. Before implementing mass screening programs, improving awareness of CRC and promoting the physicians' role are necessary to increase the screening participation rates.

RESUMO

BACKGROUND AND AIM: Colorectal cancer (CRC) screening improves survival and requires appropriate recommendation by general practitioners (GPs). Screening practises may be influenced by barriers related to ethnicity and training. METHODS: A mail survey assessed GPs' practises and the barriers towards CRC screening. The association of screening practises and demography, including GP ethnicity, medical training and practise characteristics, were evaluated. RESULTS: Of 212 GPs (median age 54 years, 73% men, 27% Caucasian, 38% foreign graduates), 87% agreed that fecal occult blood test (FOBT) screening improved survival in the average-risk patient. Considerable variations existed in the starting age (40-49 years: 31%; 50 years: 65%) and frequency (1-2 years: 77%; 3-5 years: 22%) of screening. FOBT was used for indications other than screening: anemia (59%), altered bowel habits (54%), abdominal pain (24%), and rectal bleeding (23%), and these were significantly more frequent in Asian GPs independent of medical training. GPs were less likely to recommend screening to immigrants, and most reported that immigrants were less likely to participate. More Asian and Middle Eastern GPs reported a major barrier with FOBT inaccuracy compared with Caucasian GPs (22% vs 9%, P = 0.03; and 27% vs 9%, P = 0.03, respectively). CONCLUSIONS: Considerable differences existed in GPs' CRC screening practises. Indications for use of FOBT and the subsequent investigation of a positive FOBT also varied according to GPs' ethnicity, independent of medical training. Patient's ethnicity and associated language and cultural barriers may affect screening uptake, which may negatively affect the health of immigrants. Resources and culture-specific interventions are recommended to improve overall screening participation.

RESUMO

Positron emission tomography (PET) is a well-established and integral component of multimodality imaging in oncology. However, the expanded use of PET in oncological and also non-oncological imaging (such as in assessing inflammatory conditions) has identified more lesions or tumors at unsuspected locations, such as in the large bowel during examination of patients not known to have colorectal disease. We review the clinical significance of colon lesions that were discovered incidentally by PET imaging and management strategies for gastroenterologists.

RESUMO

BACKGROUND: Colorectal cancer (CRC) screening improves survival and its success depends on the participation of the at-risk population. Few studies have adequately assessed screening knowledge, perception and participation according to birthplace. This study assesses the knowledge and perception of CRC in an ethnically diverse population, and evaluates the association with screening participation and intention. Identification of specific predictors of screening may aid the development of interventions to improve overall CRC screening. METHODS: An interview-based survey, conducted on subjects aged 30-70 years, assessed knowledge and perception towards CRC and screening tests. Primary endpoints were screening participation and intent. Statistical methods used were Chi-square, Mann-Whitney U and logistic regression. RESULTS: A total of 543 subjects (43% males, 53% Australian-born (AB), 63% aged 50 years and above) were recruited. Compared with AB, non-Australian-born (NAB) respondents had poorer knowledge, and NAB background predicted for poorer knowledge independent of sex, education, media and familiarity with CRC patient. Compared with AB respondents aged 50 years and above, NAB respondents had lower screening participation (17.4% vs. 31.8%; P=0.01), lesser intention (75.8% vs. 90.5%; P<0.001), and had received fewer doctors' screening recommendations (16.5% vs. 27.1%; P=0.04). In multivariate analysis, doctors' recommendation, media and improved perception independently predicted screening participation; knowledge and media exposure predicted intent. CONCLUSIONS: The knowledge of CRC and screening is significantly poorer in the immigrant population. Knowledge predicts for greater screening intent. Therefore, implementing language- and culture-specific educational programs involving medical practitioners and media are necessary to improve CRC screening participation rates.

RESUMO

Sex significantly influences the clinical and pathological characteristics of colorectal cancer (CRC). These include differences in incidence and mortality rates, clinical presentations including age, emergency surgery for complications from CRC, screening participation rates, site, stage and treatment utilization, histopathology and survival. Environmental, behavioral and biological factors contribute to the differential risk. Recent advances in the molecular biology of CRC, specifically in microsatellite status, estrogen hormone and estrogen receptor beta, have led to greater understanding of the effect of estrogen in colorectal carcinogenesis. Estrogen may preferentially protect against microsatellite unstable cancers through its effect on selected molecular targets; however, the exact pathways have not been elucidated. Recognition of important sex disparities in these areas may lead to the implementation of specific measures to diminish these differences and facilitate equitable distribution of health resources. Identifying specific molecular targets on CRC that interact with estrogen may stimulate research to improve the overall outcomes of all patients with CRC.

RESUMO

BACKGROUND & AIMS: The influence of birthplace on the clinical and pathologic outcomes of colorectal cancer (CRC) in Australia is unknown. Addressing inequalities in health care provision in immigrant groups may improve the overall quality of CRC care. METHODS: The South Western Sydney Colorectal Tumour Group registry prospectively collects data on new patients with CRC from a population of 800,000. Survival data were cross-linked with the New South Wales population death registry. RESULTS: From 1997 to 2004 there were 1496 patients (55% males) who were recruited and grouped according to country of birth: Australia, 64%; Southern Europe, 19%; Asia, 12%; and the Middle East, 5%. Significant heterogeneity in CRC characteristics was found, especially in Asians. Compared with Australians, Asians were diagnosed at a younger age (median age, 64 vs 70 y; P < .001, 25.6% were younger than 50 years vs 9.5%; P < .001), had fewer poorly differentiated cancers (8.9% vs 17.7%; P = .004), and fewer metastatic cancers (12.1% vs 21.0%; P = .001). Being Asian-born was associated with improved overall survival independent of age, emergency surgery, grade, and stage (hazard ratio, 0.66; 95% confidence interval, 0.47-0.93; P = 0.02). CRC screening was especially low among Asian- and Middle Eastern-born patients. Complications and treatment were not affected by birthplace, indicating no differences in the provision or acceptance of care based on birthplace. CONCLUSIONS: Despite an equitable distribution of resources, we found significant heterogeneity in presentations and outcomes according to birthplace, with improved survival in Asian-born patients. The lower rates of screen-detected CRC in Asian- and Middle Eastern-born patients and their younger ages at diagnosis indicate that targeted screening strategies may need to be implemented.

RESUMO

BACKGROUND: Studies have reported the effect of gender in the context of assessing predictors of survival from colorectal cancer (CRC); however, few have specifically addressed the impact of gender on the clinical and pathological outcomes of CRC. Appreciation of gender disparities may assist in the implementation of measures to address these differences, and improve the overall outcomes of patients with CRC. METHODS: The South Western Sydney Colorectal Tumour Group registry, which encompasses a population in excess of 800,000, prospectively collects data on new patients with CRC. Data from 1997 to 2004 were collected, including demography, site, grade, histopathology, stage, treatment, and survival. RESULTS: In total, 2,050 consecutive patients (44% women) with CRC were analyzed. Compared to men, women were older (median 69 yr, range 27-95 yr vs 67, range 22-92 yr, P= 0.001), had more emergency surgery for CRC-related complications (18.8%vs 15.1%, P= 0.03), had more proximal cancers (42.2%vs 31.5%, P < 0.001), had more poorly differentiated cancers (16.9%vs 12.9%, P= 0.01), and had fewer radiotherapy treatments for Dukes B and C rectal cancers (36.4%vs 48.1%, P= 0.02). Young women (aged 50 yr and below) had significantly better overall survival compared to young men; in this group, female gender predicted improved overall survival independent of age, emergency surgery, site, grade, and stage (hazard ratio [HR] 0.46, 95% confidence interval [CI] 0.25-0.86, P= 0.01). Similarly, young women had significantly better cancer-specific survival (HR 0.46, 95% CI 0.25-0.85, P= 0.01). However, older women (aged over 50 yr) had worse survival independent of age, emergency surgery, site, grade, and stage (HR 1.38, 95% CI 1.14-1.68, P= 0.001). There were no gender differences in screening, histopathology, stage, or utilization of chemotherapy. CONCLUSIONS: This study demonstrated an opposing effect of gender on overall and cancer-specific survival at either side of the age of 50 yr. The protective effect of estrogen on CRC may be an important factor. Women had a greater proportion of emergency surgery, which was related to the predominance of proximal cancers in this gender. Women also had more proximal cancers, thereby limiting flexible sigmoidoscopy as a screening test.

RESUMO

BACKGROUND: Obscure GI bleeding (OGIB) accounts for about 5% of all patients with GI bleeding. There are limited data on double-balloon enteroscopy (DBE) after a positive finding on capsule endoscopy (CE) in this setting. OBJECTIVE: To determine the clinical outcomes after DBE therapy. DESIGN: Prospective single-center cohort study. SETTING: Tertiary referral university hospital. MAIN OUTCOME MEASUREMENTS: Recurrent bleeding and blood transfusion requirements. PATIENTS AND METHODS: This prospective study of 60 consecutive patients with OGIB was conducted between July 2004 and March 2006. Patients underwent CE before DBE to target the lesion for either further diagnostic evaluation or therapeutic intervention. The mean (standard deviation [SD]) duration of follow-up was 10.0 +/- 5.2 months. RESULTS: The mean (SD) age was 62 +/- 18 years, with 31 men. A total of 74 DBE procedures were performed. An abnormality was seen by DBE in 45 patients (75%). In 12 patients (20%), a diagnosis was clarified or a new diagnosis was made. Therapy at DBE was performed in 34 patients (57%): 30 diathermies and 4 polypectomies. Endoscopic tattooing for targeted surgical removal was made in 3 additional patients. Multiple logistic regression analysis identified previous blood transfusion (odds ratio 10.5, 95% confidence interval 3.1-35; P < .001) to be the only independent predictor that required endoscopic therapy at DBE. Forty-eight patients (80%) had no further bleeding, and 46 patients (77%) had a normal Hb. Blood transfusion requirements fell from 34 patients to 10, P < .001. One patient had a perforation after therapeutic diathermy. LIMITATIONS: Nonrandomized study. CONCLUSIONS: In patients with OGIB and a positive finding on CE, DBE provided a safe and ambulatory method to achieve an excellent clinical outcome with significant reductions in recurrent bleeding and blood-transfusion requirements.

RESUMO

BACKGROUND: Double-balloon enteroscopy (DBE) is a new technique, recently described by its innovator, and it is seen to be beneficial in the diagnosis and management of small-bowel disease. OBJECTIVE: To evaluate this new technique in consecutive patients with suspected small-bowel disease. DESIGN: Single-center prospective study. SETTING: Tertiary referral hospital, conducted from July to December 2004. PATIENTS: Forty consecutive patients with suspected small-bowel disease referred for DBE, mean age of 58 years (range, 14-89 years), 17 men. INTERVENTIONS: Endoscopic biopsies or therapy was performed as clinically indicated. MAIN OUTCOME MEASUREMENTS: Significant diagnostic input and therapeutic intervention based on clinical outcomes. RESULTS: Indications included obscure GI bleeding (18), iron deficiency anemia (6), anemia of chronic disease (4), acute obscure GI bleeding (4), abdominal pain with other symptoms (4), Crohn's disease (3), and abdominal pain alone (1). Nineteen patients (47.5%) had a small-bowel finding, with 30 of 40 (75%) of the patients having a significant diagnostic input. Intervention was performed in 13 (32.5%) patients with success in 10 (77%). The only variable significantly associated with therapeutic success was a previous history of blood transfusions (p < 0.01). This was the only independent predictor identified by multiple logistic regression analysis (Odds ratio 13.5: 95% confidence interval [1.5, 120]). One perforation from contact diathermy occurred. In 10 attempts at total enteroscopy, none were successful. LIMITATIONS: Nonblinded nonrandomized study. CONCLUSIONS: These early data suggest DBE to be effective in the diagnosis and the therapy of small-bowel disease, particularly those patients with a history of blood transfusion.
