Ulcerative colitis (UC) and Crohn’s disease (CD) are two major inflammatory disorders of the intestinal wall collectively known as inflammatory bowel disease (IBD). Colorectal carcinoma (CRC) is the most significant and grave consequence of IBD and is preceded by dysplasia in majority of the cases. In this review we aim to discuss the various types of dysplasia found in patients with CRC due to IBD. A thorough literature search was conducted in online databases such as PubMed, Google Scholar, from which all studies published in the last ten years were included in this review. The major development in diagnostic procedures and visualization modalities have aided our understanding of dysplasia, which is now known to be the strongest predictor and marker for CRC development. However, the unpredictable behavior and progression of dysplasia still warrants vigilant surveillance. Dysplasia has been classified on histological characteristics using grades of dysplasia from ‘negative for dysplasia’ to ‘high grade dysplasia’. On visibility via an endoscope from ‘visible dysplasia’ to ‘invisible dysplasia’ and macroscopic features of ‘conventional dysplasia’ and ‘non-conventional dysplasia’. No single classification can be utilized to define the stage of dysplasia and more importantly predict its progression and outcome of CRC. Using evidence-based medicine an integrated classification expanding on a management algorithm must be formulated by a panel of experts to steer management of the disease. A multidisciplinary, tailored approach with a strong emphasis on regular and timely surveillance to ensure early detection of CRC can enhance quality of life and patient outcomes.
Post-cholecystectomy syndrome is suspected when the patients complain about the persistent presence of pain in the right upper abdominal quadrant. Other symptoms might appear which are related to the gastrointestinal tract. These symptoms appear after performing cholecystectomy. The manifestations are usually similar to those experienced before the procedure. In this study, the aim to conduct a literature review to increase the knowledge and to explore facts related to the clinical patterns and causes of post-cholecystectomy syndrome. The most commonly reported cause of this syndrome is the prior development of an extra-biliary disorder, which includes many modalities as peptic ulcer, reflux esophagitis, chronic pancreatitis, irritable bowel syndrome, and biliary-related disorders. However, the etiology of postcholecystectomy is hugely variable across the different studies in the literature. Patients that develop postcholecystectomy syndrome usually present with non-specific gastrointestinal symptoms that may or may not be similar to the symptoms that were exhibited before conducting the surgery. Some of the common physiological changes that have been reported with postcholecystectomy syndrome include the disruption of cholecysto-antral reflex, the cholecystosphincter of oddi reflex, and the cholecysto-esophageal related reflexes. In addition, the development of other changes that can significantly affect the normal physiology of the gastrointestinal tract leads to the development of significant symptoms and clinical patterns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
