Filter by:Hernia formation at sites of ostomy closure is a common complication. The investigator believes that using evidence based hernia repair techniques as a preventive measure during closure of ostomies will reduce the incidence of hernia formation. In this trial, the investigator will pilot a novel technique of monofilament bioresorbable mesh reinforcement of the abdominal wall defects that remain after closure of an ileostomy to evaluate for safety and begin to evaluate the effectiveness compared to standard techniques.
It has been reported that 62% of all people with Spinal Cord Injury (SCI) have experienced faecal incontinence and that neurogenic bowel dysfunction (NBD) is a major sequela. As an alternative to abdominal massage or the use of suppositories, the electrical stimulation (ES) of the abdominal wall has been shown to be effective in decreasing the bowel transit time as well as decreasing constipation in children with slow-transit constipation. Due to the intrinsic nature of the guts' innervation, we expect to reproduce these positive effects in people with SCI through administration of neuromuscular electrical stimulation (NMES).
The aim of this study is to discover inflammatory changes in the gastrointestinal tract in adult patients with suspicion of a chronic inflammatory bowel disease (IBD) by examining the entire bowel, including the small intestine, by using a video capsule. The study compares the video capsule endoscopy with colonoscopy with the question of inflammation and patient satisfaction with the respective examinations. The study is aimed at participants who present to a gastroenterologist because of their complaints like persistent abdominal pain or diarrhea. An infectious genesis and celiac disease must be ruled out in advance. In addition, the determination of the fecal calprotectin (fCal) is necessary for this study. Fecal calprotectin is a stool marker for the severity of an inflammation of the gastrointestinal tract, an increased fecal calprotectin can be an initial indication for the presence of a chronic inflammatory bowel disease. As mentioned above, participants will be examined in one of two ways: either with an examination of the small and large intestines using video capsule endoscopy in one examination (i.e. ,panintestinal capsule endoscopy', PICE) or a colonoscopy is performed as the standard treatment. Which of the two methods is used will be decided by lot, electronically controlled. Colon cleansing is necessary in preparation for both examinations. The advantage of being assigned to the video capsule group is, in addition to showing the entire intestine in one examination, that no sedation is necessary for this examination. In addition to the examination, participants have to fill out a questionnaire with information about their state of affairs, their well-being and their experience with the examination. After a period of six month the participants will be contact by phone to inquire about their current state of health.
In the general population, the percentage of people with at least one digestive disease is 16.7%. Among these digestive diseases, inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and patients who should benefit from digestive examinations as part of a screening oriented either by the patient's family history or following the performance of an immunological screening test ( FIT) in the stool will be studied. The aim of this project is to build a biological collection with associated clinical data for research projects.
Descriptive study, in which the haemostatic profile of ambulatory patients with IBD will be analyzed by means of ROTEM and other techniques, such as the thrombin generation test and the study of platelet function by flow cytometry.
In Latin America, inadequate treatment adherence and compliance in IBD patients is around 64% in Brazilians, 54.4% in Mexicans and 50.3% in Argentinians. In industrialised countries, it has been described that in IBD patients, features as younger age, low disease-related knowledge or low treatment adherence and compliance are negatively associated with health-related quality of life (HRQoL). The following research pursues to better understand potential factors related to IBD patients' treatment adherence and compliance as well as patients' IBD-related knowledge level in a Latin American population, and their preferences and barriers when interacting with ICTs for clinical purposes; to develop and to validate an IBD MAHS for Spanish-Speaking patients with Crohn's and ulcerative colitis.
Inflammatory bowel diseases (IBD) are chronic inflammatory disorders that can be categorized as ulcerative colitis (UC), Crohn's disease (CD) and indeterminate colitis (IC). Deep remission has been shown to improve disease outcome. There may be a lack of concordance between endoscopic and histologic remission. IBD patients with long standing colitis are at risk of developing dysplasia and colorectal cancer (CRC). However, it can be challenging to diagnose dysplasia in IBD patients during colonoscopy, as dysplasia frequently manifests as non-pedunculated lesions that present with only subtle visible changes or are even invisible due to the surrounding inflammation, scarring, pseudopolyps, or hyperplasia. Although white light endoscopy and chromoendoscopy are the current standard modality of imaging, there is still a gap to be bridged, in terms of improving endoscopic diagnosis of dysplasia and improving concordance of endoscopic and histologic remission. Raman spectroscopy is an inelastic light scattering technique provide specific fingerprints of molecular compositions and structures of biological tissues. It may be able to provide additional diagnostic information over standard endoscopy. A second-generation Raman endoscope system for improving in vivo tissue characterization and diagnosis during colonoscopy has been developed (SPECTRA IMDx system). Preliminary data suggested its utility in the diagnosis of colorectal neoplasia during colonoscopy. There is currently a lack of data concerning the application of this novel technology in the context of IBD. Specifically, whether the spectral signals generated can be used to better classify disease remission, and thus achieve higher concordance with histology when compared to standard endoscopy. It is also unclear whether this technology can be used to differentiate dysplastic mucosa from non-dysplastic mucosal in IBD patients. Hypotheses 1. Raman spectroscopy based artificial intelligence system has the potential to be used to differentiate disease remission from active mucosal inflammation and hence improve concordance between endoscopic and histologic remission, with the potential to decrease the need for random biopsies real-time during colonoscopy. 2. Raman spectroscopy based artificial intelligence system has the potential to differentiate dysplastic mucosa in IBD patients (low grade and high grade dysplasia; colorectal cancer) from non-dysplastic mucosa. real-time during colonoscopy.
In a randomized controlled study to evaluate the effect of acupressure application on opioid-related constipation, the Patient Identification Form, Defecation Diary, Visual Analog Scale and Constipation Quality of Life Scale will be applied after obtaining written informed consent from the patients. Patients in the experimental group will be given acupressure once a day for 7 consecutive days. Acupressure application will be applied by researchers who have been trained and certified on this subject. While the patients are in supine position, pressure will be applied to each acupressure point around the navel, respectively, Zhongwan (CV12), Guanyuan (CV4) and Tianshu (ST25) for 2 minutes for a total of 6 minutes. No attempt will be made to the control group. All patients will be followed for a total of 4 weeks and the Defecation Diary and Visual Comparison Scale will be applied weekly. 4. Constipation Quality of Life Scale will be applied again at the end of the week. The study was planned to examine the effect of acupressure on opioid-related constipation.
To develop and train a convolutional neural network to detect and characterize disease severity of inflammatory bowel disease during endoscopy
In this study it will be explored whether the levels of fecal biomarkers are associated with histologic inflammation of the intestinal mucosa and concomitant alteration of the mucosal permeability. The aim of the study is to assess the diagnostic accuracy of fecal biomarkers especially to detect the potential of differentiation between inflammatory and functional gastrointestinal diseases. The following biomarkers will be examined in the stool of the participants: calprotectin, lactoferrin, pmn-elastase, human beta-defensin, zonulin, alpha-antitrypsin.
