Scintigraphic Evaluation of IPAA Function in Patients With Ulcerative Colitis

Ulcerative Colitis

The aim of this study is to evaluate scintigraphic methods as objective factors for functional outcome in patients treated with ileal-pouch-anal anastomosis (IPAA). The gastrointestinal transit-time and the degree of evacuation are evaluated in relation to the functional outcome.

Predictive Factors of Endoscopic Mucosal Healing in Quiescent Ulcerative Colitis

Ulcerative Colitis

The purpose of this study is to determine whether fecal calprotectin, fecal immunochemical test, and Rome III criteria for irritable bowel syndrome (IBS) can predict mucosal healing in patients with quiescent ulcerative colitis (UC).

Digital Holographic Microscopy: Evaluation of Histological Disease Activity in Patients With Ulcerative...

ColitisUlcerative1 more

Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.

Indigo Carmine Staining and Narrow Band Imaging (NBI) of Colonic Mucosa for Detection of Dysplasia...

Ulcerative Colitis

A prospective, randomized trial to determine indigo carmine dye spraying and narrow band imaging (NBI) of colonic mucosa to detect dysplasia in ulcerative colitis (UC). Confocal laser microscopy may be beneficial in the further assessment of abnormalities identified by these methods.

This study is being done to: To attempt to increase the detection of precancerous colon tissue in patients with chronic ulcerative colitis and primary sclerosing cholangitis; To determine if an investigational scope that can look at the lining of the colon in different ways will help the doctor identify abnormal tissue in patients with chronic ulcerative colitis and concurrent primary sclerosing cholangitis; and To determine if this investigational scope can accurately detect precancerous or cancerous tissue in patients with chronic ulcerative colitis that are known to have had cancerous or precancerous tissue in the past.

Endoscopic Ultrasound Determines Disease Activity in Crohn's Disease And Ulcerative Colitis

Crohn DiseaseUlcerative Colitis

Although Crohn's disease and ulcerative colitis are the main subtypes of inflammatory bowel disease, they differ substantially in disease behavior, prognosis, and treatment paradigm. However, making an accurate diagnosis of Crohn's disease versus ulcerative colitis and assessing disease activity beyond the level of mucosal inflammation remain challenging with contemporary modalities. The objective of the study is to determine the novel role of endoscopic ultrasound in A) differentiating Crohn's colitis versus ulcerative colitis and B) monitoring disease activity in these patients.

Identify Predictors That Distinguish Between Tofacitinib Responders and Non-responders Based on...

Ulcerative Colitis

This is a prospective cohort study enrolling ulcerative colitis patients who initiate tofacitinib therapy. Investigators will collect clinical data, blood and stool samples prior to initiation of tofacitinib and, at minimum, monthly after the start of therapy. They will collect tissue from colonoscopies prior to initiation of therapy and within 6 months on therapy. Clinical characteristics and response to treatment will then be associated with genotype, blood immune profiles, stool microbiota, and cellular and molecular profiles of the biopsies to generate a treatment response model. Using predictors identified in our model, we will then attempt to validate the model and findings with the OCTAVE (Pfizer), SPARC (CCF), and RISK (CCF) data.

Subjective Near-infrared Fluorescence Guidance in Perfusion Assessment of Ileal Pouch Formation...

Ulcerative ColitisColorectal Cancer4 more

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. The intraoperative imaging findings are then analysed and correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.
