BACKGROUND Compared with short and long chain fatty acids, medium chain fatty acids (MCFAs) have been shown to provide the highest colonic absorption of substrate carbon. Moreover, colonic epithelial cells fulfil their basic energy requirements as easily from MCFAs as from short chain fatty acids. AIMS To further characterise octanoate as a colonic luminal substrate, we determined in vivo the...

The treatment strategy of colonic injuries is a debatable and highly controversial subject worldwide in various medical centers. The method of treatment of left and .. right colonic injuries, diversity or similarity in their management and particularly differences between the treatment of war-associated injury from other types of colonic damage are among the unsettled issues. The present s...

Gastrointestinal (GI) fistula is a well-recognized complication of acute pancreatitis (AP). However, it has been reported in limited literature. This study aimed to evaluate the incidence and outcome of GI fistulas in AP patients complicated with infected pancreatic or peripancreatic necrosis (IPN).Between 2010 and 2013 AP patients with IPN who diagnosed with GI fistula in our center were analy...

OBJECTIVES To compare three radiological scores in the study of fecal impaction in children with constipation. To investigate whether these radiological scores are useful in the assessment of fecal disimpaction therapy and if they present a relation with total colonic transit time. METHODS The Barr, Blethyn and Leech scores were measured by three observers, independently, in 123 abdominal rad...

Antibodies against Saccharomyces cerevisiae (ASCA) and Escherichia coli outer membrane porin C (anti-OmpC) are known to be detectable in the serum of patients with Crohn's disease (CD) but display a very poor sensitivity for the disease especially in forms with isolated colonic involvement. In this study we aimed at evaluating performances of these markers in supernatant of cultured colonic bio...

It is estimated that most colon cancers can be attributed to dietary causes. We have hypothesized that diet influences the health of the colonic mucosa through interaction with the microbiota and that it is the milieu interior that regulates mucosal proliferation and therefore cancer risk. To validate this further, we compared colonic contents from healthy 50- to 65-y-old people from population...

Population studies suggest that greater dietary fiber intake may lower colorectal cancer (CRC) risk, possibly through the colonic bacterial fermentative production of butyrate. Butyrylated starch delivers butyrate to the colon of humans with potential to reduce CRC risk but high doses may exacerbate risk through promoting epithelial proliferation. Here we report the effects of increasing dietar...

To determine if imaging findings on computed tomography (CT) can predict the need of surgery in patients with idiopathic mesenteric phlebosclerosis (IMP).This retrospective study included 28 patients with IMP. Abdominal CT images were reviewed to determine the extent and severity of mesenteric calcifications and the presence of findings related to colitides. We compared the number of colonic se...

Capillary blood flow in the canine colon and other organs has been assessed over a wide range of portal pressures using radio-labelled microspheres. The proximal colon received a greater proportionate flow than the distal region. At both normal and raised pressures, the mucosa received 90% of the total colonic capillary flow. A highly significant negative correlation (P less than 0.001) was fou...
