Abstract
Summary
A technic is described for sampling the contents of the intestinal tract in human subjects repeatedly and at various intestinal levels over a 1-2 week intubation period. Prolonged transintestinal intubation with polyvinyl tubing (2.1 mm OD) has been well tolerated, and sampling has been effected under conditions which closely approach the physiological state. A means of localizing the site of aspiration is described. Reproducible measurements of the length of the intestinal tract have been made in 8 adult patients.
