Evaluating the Efficacy of Fecal Immunochemical Test, Fecal Calprotectin, and Serum C-Reactive Protein in Diagnosing Patients With Chronic Lower Gastrointestinal Symptoms.

Introduction: Accurate early detection of ileocolonic lesions in patients with chronic lower gastrointestinal symptoms (LGISs) is often difficult due to the rarity of early-stage alarm signs. This study assesses the effectiveness of noninvasive blood and stool biomarkers in diagnosing ileocolonic lesions in patients with chronic LGISs undergoing colonoscopy.

Methods: We conducted a prospective study between April 2020 and July 2022 involving patients with LGISs lasting a month or more.

"MURAL" model to predict bleeding from mural-based lesions in potential small bowel bleeding may improve diagnostic capability and decrease cost.

In potential small bowel bleeding, video capsule endoscopy (VCE) is excellent to detect mucosal lesions, while mural-based lesions are better detected by computed tomography enterography (CTE). A predictive tool to identify mural-based lesions should guide selecting investigations. In this retrospective study, we developed and validated the "MURAL" model based on logistic regression to predicts bleeding from mural-based lesions.

Negative Video Capsule Endoscopy Had a High Negative Predictive Value for Small Bowel Lesions, but Diagnostic Capability May Be Lower in Young Patients with Overt Bleeding.

Background: Patients with potential small bowel bleeding (PSBB) who have negative results of video capsule endoscopy (VCE), clinical course, rate of rebleeding, and missed lesions with their predictors are essential for further management decision.

Methods: This retrospective study included patients presenting with PSBB who had negative VCE findings between January 2008 and December 2016. All patients had to have at least two years of follow-up data to be included.

Temporal trend of disease recognition, treatment paradigm, and clinical outcomes of Crohn disease in Thailand from 2000 through 2017: Is early use of thiopurines beneficial?

The prevalence of Crohn disease (CD) is increasing in Asia, but data from Southeast Asian population are scarce.The databases of 2 university-based national tertiary referral centers located in Bangkok, Thailand, were retrospectively reviewed for adult patients diagnosed with CD during January 2000 to December 2017. Disease characteristics, diagnosis, treatment, and outcomes were described and compared between the 2000 to 2009 cohort (cohort A) and the 2010 to 2017 cohort (cohort B).

Temporal trend in the natural history of ulcerative colitis in a country with a low incidence of ulcerative colitis from 2000 through 2018.

Background/aims: The incidence of ulcerative colitis (UC) in Thailand (crude incidence rate of 0.28 per 100,000 persons) is much lower than in the West. The burden of UC varies in different populations.
