To obtain wide scanning field with high resolution and improve visualizability in ultrasonic examination
of the pancreas, a new method was developed with the aid of Potato Starch Gel.
The whole procedures are as follows: (1) Butropium bromide (4 mg) is given intramuscularly in fasting
state. (2) 300 ml of 10% Potato Starch Gel is ingested about 5 minutes after the injection. (3) Scans are mainly performed with sitting position and occasionally with right decubitus position by linear electronic equipment.
In three cases which poorly visualized the pancreas by filling stomach with water, we tried to do that by
filling stomach with Potato Starch Gel and obtained the improved visualizability. We think that Potato Starch
Gel expand the indication of a filling stomach method than the liquid like water.
In the same 37 subjects, we compared the visualization rate of this method with that of conventional
method, we found that the remarkable improvement of the visualization in this method was in the tail and
in 81% of them the head, in 97% the body and in 78% the tail were well visualized in this method. We believe
that this method sufficiently contribute to the improved visualizability of the whole pancreas, especially in
