Push enteroscopy alters management in a majority of patients with obscure gastrointestinal bleeding.

Introduction: Although enteroscopy has been increasingly used to investigate occult or obscure bleeding, little is known about its impact on patient management. The aim of the present paper was to evaluate both the diagnostic yield and the impact of push enteroscopy on the management of patients referred to a tertiary Australian institution.

Methods: Data were collected prospectively in all patients undergoing push enteroscopy at Royal Adelaide Hospital.

Upper gastrointestinal responses to intraduodenal nutrient in type 1 diabetes mellitus.

Background: Abnormal nutrient-related small-intestinal feedback may contribute to disordered gastric motility and upper gastrointestinal symptoms in patients with diabetes.

Aim: To evaluate the motor, sensory and incretin responses to intraduodenal nutrients in patients with type 1 diabetes and in controls.

Methods: Eight type 1 diabetes patients (two with autonomic neuropathy) and nine controls were studied during euglycaemia.
