The primary objective is to obtain stool samples from subjects with symptoms of an undiagnosed gastrointestinal disorder. All subjects enrolled in the study will undergo a colonoscopy.
Rationale: Since January 2014 the Dutch screening programme for bowel cancer has been implemented. Screening will increase the demand for surveillance. Although patients in whom adenomas h...
The primary objective of this study is to obtain de-identified, clinically characterized, stool and plasma specimens for use in assessing new markers for the detection of neoplasms of the ...
The primary objective of this study is to gather stool samples from subjects with inflammatory bowel disease (IBD) to be added to a test set of stool samples that will be utilized to help ...
Computed tomography (CT) colonography has gained widespread multi-disciplinary interest as an evolving noninvasive colorectal screening examination, with the potential of improved patient ...
Forty-four-year-old male with ulcerative colitis (UC) for 11 years reported frequent relapse despite daily sulfasalazine 4 g, azathioprine 125 mg, and rectal 5-aminosalicylic acid. Repeated use of ...
To minimize the sample variability of liver biopsy, the tissue length should be at least 25 mm. Consequently, more than one biopsy pass is needed with cutting biopsy needles. We aimed to investigate...
Non-invasive detection and monitoring of inflammatory bowel disease (IBD) is an important clinical challenge. Stool calprotectin is the most popular among available options, but the necessity of stool...
Inadequate bowel preparation during screening colonoscopy necessitates repeating colonoscopy. Studies suggest inadequate bowel preparation rates of 20-60%. This increases the cost of colonoscopy for o...
Tuberculosis (TB) continues to result in high morbidity and mortality in children from resource-limited settings. Diagnostic challenges, including resource-intense sputum collection methods and insens...
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show infiltration of LYMPHOCYTES in the superficial EPITHELIUM and the underlying connective tissue (lamina propria).
A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.
