Researchers at U-M Health System found that disease severity in patients with ulcerative colitis can be accurately evaluated without frequent lower endoscopies. The study suggests using non-invasive indices, such as patient-reported symptoms, to monitor disease activity and spare patients the discomfort of regular endoscopies.
The American Gastroenterological Association recommends colonoscopy as the preferred screening method for colorectal cancer due to its ability to detect and remove precancerous polyps. In-office fecal occult blood tests are not recommended as a standalone screening test, but can be used in conjunction with flexible sigmoidoscopy.
A study of 43 patients found that 71% who used NSAIDs for over 90 days had visible injury to their small intestine, ranging from small erosions to severe ulcers. The study highlights the potential risks of long-term NSAID use and calls for further research on the clinical significance of these findings.
A study estimates that 41 million Americans are eligible for colorectal cancer screening, but only a fraction have received it. The capacity for screening tests like flexible sigmoidoscopy and colonoscopy is limited, with colonoscopies being the most expensive option.
CT colonography offers improved accuracy and convenience for colorectal cancer screening, but challenges remain in standardization, patient preparation, and interpretation of results. Standardization and training are necessary for widespread adoption.
A retrospective cohort study of 198 children who underwent fundoplication at Texas Children's Hospital from 1996-1999 found that fundoplication is not a long-term solution for treating GERD in children. Alternative medical treatments, such as histamine-2 receptor antagonists and proton pump inhibitors, are recommended instead.
Increased use of virtual colonoscopy is expected to lead to a decrease in traditional colonoscopies due to improved detection rates. Virtual colonoscopy without bowel preparation has been found to be as effective as traditional colonoscopy in detecting colorectal polyps, increasing patient compliance and potential screening rates.
A study found that cigarette smokers are more likely to have polyps, a greater number of polyps, and larger polyps than non-smokers. Vitamin C supplements were also associated with the absence of polyps in patients who regularly consumed them.
A new trial shows promising results for Cilansetron in treating IBS with diarrhea, improving quality of life and relieving symptoms. The medication has been shown to be well-tolerated and efficacious in both men and women.
A new study identifies 38 patients under 50 with colorectal cancer, half with family history. The research concludes that African-Americans and Hispanics should begin screening at age 40 regardless of family history.
A new study on celiac disease over a 52-year span reveals a significant shift in patient demographics and symptom presentation. Fewer patients are diagnosed with diarrhea, while more are discovered through screening, leading to an increase in silent diagnoses.
A retrospective cohort study of 24,918 patients with type 2 diabetes found those on more than three years of insulin therapy have a significantly higher risk of developing colorectal cancer. The study's lead author hopes the findings will lead to more effective cancer prevention efforts.
Virtual colonoscopy shows significant promise for colorectal cancer screening, but practical issues must be addressed before widespread use. Issues include standardization of test performance and interpretation of results, as well as the potential need for multiple procedures to detect and remove polyps.
The American College of Gastroenterology states that colonoscopy is the best and gold-standard test for colorectal cancer screening and prevention. It prevents about 80 percent of colorectal cancers from developing by removing precancerous polyps, while CT colonography has shown poor results in comparison.
Virtual colonoscopy has shown promise as a colorectal cancer screening option, with limitations in detecting flat polyps and varying results in clinical trials. Further research is needed to determine the optimal size for removing small growths and standardizing test performance.
Eosinophilic esophagitis (EE) is a rapidly rising disorder characterized by severely elevated levels of eosinophils in the esophagus, leading to vomiting and difficulty swallowing. The disease has a familial pattern suggesting genetic or environmental factors, warranting further study.
The American Gastroenterological Association disputes the validity of a recent study suggesting that too many surveillance colonoscopies are being performed. The study, published in Annals of Internal Medicine, highlights the importance of determining the clinical significance of small polyps and notes the need for further research to ...
Researchers found that consumer awareness of NSAID side effects has increased over time, but many patients still take excessive doses, putting themselves at risk for serious complications. The study emphasizes the need for education and discussion with physicians to recognize risk factors and prevent adverse reactions.
Researchers found that among patients with confirmed Crohn's disease, clinical decisions based on capsule endoscopy findings improved outcomes in 95% of patients. Capsule endoscopy was also 100 percent effective in excluding a diagnosis of Crohn's disease.
A large cohort study reveals that diabetes significantly increases the risk of developing chronic liver disease and liver cancer. Regular testing of liver enzymes is recommended for patients with diabetes to monitor for potential toxicity.
A substantial majority of people who purchased Prilosec OTC complied very well with the label instructions. The study found that frequent heartburn sufferers increased consultation with their physicians after using the medication.
A new study on virtual colonoscopy has shown remarkable improvement in diagnosis but also revealed significant discomfort for patients. Gastrointestinal specialists emphasize the need for verification of results and caution against relying solely on virtual colonoscopy.
Patients with achalasia often experience impeded digestion due to reduced muscle contraction and sphincter relaxation. Research finds that nerve cell loss may cause constipation in these patients, which persisted even after treatment for achalasia.
A study of nearly 2,000 patients found that heavy alcohol consumption was associated with a higher risk of colorectal cancer. Patients with significant spirits intake may benefit from more intensive screening, according to the American College of Gastroenterology.
Studies link fructose intolerance to IBS symptoms; patients with diet modifications show improved symptoms. Fat consumption is also linked to gastrointestinal disorders, according to a new study.

A study found that treating acid reflux significantly improved quality of life and reduced asthma symptoms in patients with moderate to severe persistent asthma. The use of a proton pump inhibitor, such as lansoprazole, was shown to offer significant benefits for these patients.
A new survey reveals that over 65% of IBS patients in the US experience debilitating symptoms, with 97% consulting healthcare professionals in the past three months. The study also shows significant economic burdens, with $258 average spend on GI disorders per month.
A study published by the American College of Gastroenterology found that wireless capsule endoscopy outperformed traditional push enteroscopy in detecting small intestine lesions causing obscure GI bleeding. The technology identified potential sources of bleeding in 70% of patients, compared to 45% with push enteroscopy.
Researchers found that smoking is an important risk factor for developing colorectal polyps, with smokers being more likely to have larger polyps and a greater potential for malignancy. The study suggests that physicians should consider performing screening colonoscopy in current smokers before age 50.
A significant number of patients use the internet as a source of medical information, with over 25% using it in the last year. Physicians should initiate dialogue early on concerning where patients should look for accurate, comprehensive and understandable online health information.
Duke University researchers conclude that physicians who achieve an 80% success rate in endoscopic retrograde cholangiopancreatography (ERCP) are adequately trained, regardless of the number of procedures performed. This finding challenges the common assumption that more procedures equal competence.
