Gillingham, Melanie B., Elizabeth M. Dahly, Hannah V. Carey, Melanee D. Clark, Karen R.. Kritsch, and Denise M. Ney. Differential jejunal and colonic adaptation due to resection and IGF-I in parenterally fed rats. Am J Physiol Gastrointest Liver Physiol 278: G700–G709, 2000.— Patients with severe short-bowel syndrome (SBS) often require long-term total parenteral nutrition (TPN) to maintain the...
A 39-year-old man was admitted to our hospital for acute epigastric pain with nausea and vomiting. Physical examination was suggestive for acute abdomen without peritoneal irritation findings. Blood tests results were as follow: alanine aminotransferase (ALT): 87 U/L, aspartate aminotransferase (AST): 55 U/L, amylase: 135 U/L, lipase: 69 U/L, total bilirubin: 11,6 mg/l, creatinine: 9 mg/l, C-re...
BACKGROUND Free jejunal interposition is a useful technique for reconstruction of the cervical esophagus. However, the distal anastomosis between the graft and the remaining thoracic esophagus or a gastric conduit can be technically challenging when located very low in the thoracic aperture. We here describe a modified technique for retrograde stapling of a jejunal graft to a failed gastric con...
During high-salt diet endogenous dopamine (DA) reduces jejunal sodium transport in young but not in adult rats. This study was designed to evaluate whether this effect is mediated, at the cellular level, by inhibition of Na+-K+-ATPase activity. Enzyme activity was determined in isolated jejunal cells by the rate of [γ-32P]ATP hydrolysis. Cells were obtained from weanling and adult rats fed eith...
Small intestine mucosa is often affected with malabsorptive, autoimmune and inflammatory pathological processes. However, morphometric data on the healthy human small intestine mucosa, especially ileum, are scarce. We aimed to obtain histoquantitative data on the healthy jejunal and ileal mucosa and assess the effects of gender and ageing on these parameters. Computer-aided morphometric analysi...
Serotonin and substance P of gastrointestinal origin have been measured by radioimmunoassay in the bowel lumen under basal and stimulated conditions. To investigate the possibility that local blood flow may be influenced by these endoluminal hormones, 26 cats were studied with exogenous serotonin and substance P infused endoluminally into isolated proximal jejunal segments in vivo. Regional blo...
INTRODUCTION Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as d...
