Abstract

A one session multipurpose intubation method for the investigation of diarrhoea and malabsorption is described. It enables tests for bacterial colonisation, infestations, and luminal cytology of the small intestine to be combined with a pancreatic exocrine function test and a jejunal biopsy during the same intubation. The technique has proved acceptable, reliable, diagnostically valuable, and convenient for use on outpatients.
