[Clinical significance of conventional follow-through examinations of the gastrointestinal passage in a university hospital].
OBJECTIVE
The follow-through examination (FTE) is still a widely used radiological method. Modern sectional imaging techniques (CT, MRI, sonography) are established routine examinations offering a wider range of information. In this context the study tries to answer the question of the current significance of FTE of the gastrointestinal tract.


METHODS
We retrospectively analyzed data of 300 patients, who had undergone FTE between 2001 and 2009 in a university hospital. The medical history, current anamnesis and the therapeutic consequences of the examination for each patient were evaluated based on radiological reports and electronic medical files.


RESULTS
The most frequent indication to perform the examination was an uncertain gastrointestinal passage or/and the exclusion of stenosis (70%). In 10% of all FTEs there were complications which led to examination abortion in 2% of cases. In patients who underwent surgery of the abdomen, the examination was performed 8 days (median) after surgery. In 35% of these patients, FTE was done within the first 6 days after surgery. 87% of the patients received further diagnostics before getting pharmacotherapy or surgery. None of the analyzed patients had been operated on after an FTE of the abdomen without being investigated by another diagnostic method. The average radiation exposure was 7 mSv.


CONCLUSIONS
Considering the wide availability of modern sectional imaging methods that are usually necessary for taking significant therapeutic steps, the indication for FTE examinations of the gastrointestinal tract should be very restrictive. The relatively high radiation exposure supports this suggestion.
