Gastroesophageal reflux in young children treated for esophageal atresia: evaluation with pH-multichannel intraluminal impedance
2011
Objectives: Gastroesophageal reflux (GER) and dismotility occur frequently after repair of esophageal atresia (EA). GER-associated complications can manifest either early or later; then precocious diagnosis and treatment are essential. The aim of the study was to evaluate characteristics of GER and esophageal clearance in children treated for EA with distal tracheoesophageal fistula, using pH-multichannel intraluminal impedance (pH-MII). Patients and Methods: Twenty-two children (ages 3‐40 months) treated for EA at birth, and 20 normal children of similar age with suspected GER disease were included in the study. Impedance parameters were analyzed according to age and symptoms. Results: Ref…
Conventional Radiology in the Evaluation of the Small Bowel
2015
For many years, the small bowel has been considered as the “black box” of the gastrointestinal system because it could not be evaluated through endoscopy. For this reason, the conventional radiological methods, such as small bowel enteroclysis and small bowel follow-through, have been considered the standard approach for the evaluation of the small bowel in the diagnosis and management of Crohn’s disease for years. However, due to technological limits, the study of small bowel through conventional radiology has been focused mainly on its function than on its anatomy. To date, the conventional examination with the study of intestinal transit is now rarely used, if not obsolete, but it has st…
Gastric emptying, small intestinal transit and fecal output in dystrophic (mdx) mice.
2009
Duchenne muscular dystrophy (DMD), which results from deficiency in dystrophin, a sarcolemma protein of skeletal, cardiac and smooth muscle, is characterized by progressive striated muscle degeneration, but various gastrointestinal clinical manifestations have been observed. The aim was to evaluate the possible impact of the dystrophin loss on the gastrointestinal propulsion in mdx mice (animal model for DMD). The gastric emptying of a carboxymethyl cellulose/phenol red dye non-nutrient meal was not significantly different at 20 min from gavaging between wild-type and mdx mice. The intestinal transit and the fecal output were significantly decreased in mdx versus normal animals, although th…
