BACKGROUND Dietary protein is required to attenuate the loss of muscle mass and to support recovery during a period of hospitalization. Jejunal feeding is preferred over gastric feeding in patients who are intolerant of gastric feeding. However, the impact of gastric vs. jejunal feeding on postprandial dietary protein digestion and absorption kinetics in vivo in humans remains largely unexplore...

INTRODUCTION Jejunal diverticula are rare and are usually asymptomatic. However, they may cause chronic non-specific symptoms or rarely lead to an acute presentation. CASE PRESENTATION We report the case of an 82-year-old Caucasian woman presenting with a one-day history of generalized abdominal pain, with three episodes of vomiting. An abdominal X-ray displayed multiple dilated loops of the ...

BACKGROUND This study was conducted to elucidate if nitric oxide is released by the porcine jejunal mucosa upon selective stimulation of AT2 receptors and the possible involvement of iNOS, and to investigate the presence of jejunal AT1 and AT2 receptors. Young landrace pigs were anaesthetized with ketamine and alpha-chloralose. Jejunal luminal NO output was assessed by intraluminal tonometry an...

The role of enteral or parenteral long-chain triacylglycerol (LCT) in the complex process of intestinal adaptation is poorly defined and may involve alterations in eicosanoid synthesis. Our objective was to determine whether provision of parenteral LCT stimulates eicosanoid synthesis and resection-induced intestinal adaptation. We assessed small bowel structural adaptation, the fatty acid profi...

We examined the role of vagal innervation in lipid-stimulated increases in expression and synthesis of intestinal apolipoprotein A-IV (apoA-IV). In rats with duodenal cannulas and superior mesenteric lymph fistulas given duodenal infusions of lipid emulsion, vagotomy had no effect on either intestinal lipid transport, lymphatic apoA-IV output, or jejunal mucosal apoA-IV synthesis. In rats with ...

Vagal stimulation induced by sham feeding in 11 healthy subjects was used to examine the possibility that the autonomic nervous system might be involved in the control of human jejunal absorption. Gastric acid secretion was measured from gastric aspirates corrected for recovery, and jejunal absorption was determined using a triple lumen perfusion technique. Sham feeding induced a significant in...

Rupture of jejunal artery aneurysm is a very rare event resulting in life-threatening hemorrhage in Behcet disease (BD). We report a case of ruptured jejunal artery aneurysm in a 35-year-old patient with BD. The patient had a 1-year history of intermittent abdominal pain caused by superior mesenteric artery aneurysm with thrombosis. Anticoagulation treatment showed a good response. Past surgica...

We present a rare case of functional stenosis of the jejunal loop following left hepatectomy and hepaticojejunostomy long after pylorus-preserving pancreaticoduodenectomy (PPPD), which was successfully managed by balloon dilation. A 70-year-old Korean man had undergone PPPD 6 years before due to 1.8 cm-sized distal bile duct cancer. Sudden onset of obstructive jaundice led to diagnosis of recur...
