Effects of Bolus and Continuous Nasogastric Feeding on Gastric Emptying, Small Bowel Water Content, Superior Mesenteric Artery Blood Flow, and Plasma Hormone Concentrations in Healthy Adults: A Randomized Crossover Study.

Objective: We aimed to demonstrate the effect of continuous or bolus nasogastric feeding on gastric emptying, small bowel water content, and splanchnic blood flow measured by magnetic resonance imaging (MRI) in the context of changes in plasma gastrointestinal hormone secretion.

Background: Nasogastric/nasoenteral tube feeding is often complicated by diarrhea but the contribution of feeding strategy to the etiology is unclear.

Methods: Twelve healthy adult male participants who underwent nasogastric intubation before a baseline MRI scan, received 400  mL of Resource Energy (Nestle) as a bolus over 5 minutes or continuously over 4  hours via pump in this randomized crossover study.

Endovascular treatment of a Superior Mesenteric Artery Syndrome variant secondary to traumatic pseudoaneurysm.

Pseudoaneurysms related to the superior mesenteric artery (SMA) are a recognised complication of trauma to the vessel, and successful treatment with stenting has been previously described. We report the case of a patient who presented with obstruction of the fourth part of the duodenum secondary to a traumatic pseudoaneurysm, a hitherto unreported variant of superior mesenteric artery syndrome. Exclusion of the pseudoaneurysm and relief of the duodenal obstruction were simultaneously achieved by placement of a covered stent.

Prospective, randomized, controlled, single-blind trial of the costs and consequences of systematic nutrition team follow-up over 12 mo after percutaneous endoscopic gastrostomy.

Objectives: We assessed the economic and clinical implications of systematic long-term nutrition team follow-up of patients after percutaneous endoscopic gastrostomy.

Methods: We designed a prospective, randomized, controlled, single-blind trial in a large district hospital and its catchment area. All adult patients referred for a gastrostomy were eligible and randomized into two groups.

Irritable bowel syndrome: diagnosis and symptom management.

Irritable bowel syndrome (IBS) is a very common problem affecting 10% of the population at some time. Its cause and pathogenesis, however, remain poorly understood. Diagnosis is usually straightforward and detailed investigations are only required when the presentation is atypical.

Acid reflux and gastro-oesophageal reflux disease.

Gastro-oesophageal reflux disease (GORD) is a common disease that is likely to increase in prevalence as the population becomes steadily more obese. Although generally benign reflux can, if untreated, lead to severe complications. This article describes the symptoms and diagnosis of acid reflux and GORD, and reviews currently available treatments ranging from lifestyle modification to surgery.

Artificial nutrition support in intestinal failure: principles and practice of parenteral feeding.

Patients with intestinal failure are at risk for malnutrition and its associated adverse consequences. In many of these patients it is not possible to feed via the gastrointestinal tract, and nutrients must be provided directly into the bloodstream. For some patients with irreversible intestinal failure, this is a lifelong requirement.
