The low FODMAP diet shows efficacy for IBS patients. The current strategy of breath testing and dietary advice provides a good basis to understand and adhere to the diet.
Resection for recurrent rectal cancer results in good survival with acceptable morbidity, unaffected by the extent of resection. Extended radical resection to obtain clear resection margins is the appropriate management of locally recurrent rectal cancer.
The liver sieve, formed by the fenestrated hepatic sinusoidal endothelium, is a dynamic biofilter separating the hepatic blood from the plasma within the space of Disse. It filters macromolecules of differing sizes, especially lipoproteins. More specifically, it acts as a barrier to the large triglyceride-rich parent chylomicrons, while permitting the smaller triglyceride-depleted but cholesterol- and retinol-rich remnants to enter the space of Disse. There the remnants contact specific receptor sites on the hepatocyte microvilli. Thus, the liver sieve is the first site of hepatic selection and consequent metabolism of dietary cholesterol and fat-soluble vitamins, as well as rejection of dietary triglycerides. Therefore, perturbations of the porosity of the sieve, whether from changes in size, number of fenestrae, or composition of the underlying extracellular matrix within the space of Disse, will have a profound influence on the metabolism of lipoproteins. This disturbance of the homeostasis of lipids, including fat-soluble vitamins and cholesterol, as well as other macromolecules, may tilt the balance between health and disease in a variety of organs and tissues, such as the liver, kidney and arteries.
Study Design: Review. Objectives: To outline the present knowledge of bowel dysfunction following spinal injury, and look at future directions of management and research. Setting: Spinal Unit and Colorectal Unit, Christchurch, New Zealand. Methodology: Review. Results: The underlying physiology of colorectal motility and defecation is reviewed, and consequences of spinal cord injury on defecation are reported. A discussion of present management techniques is undertaken and new directions in management and research are suggested. Conclusion: There is need for more intervention in regard to bowel function that could improve quality of life, but there is also a need for more research in this area.
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.
