Case 3
A patient after VBG. The indication for examination was weight regain and non-specific pain in the upper
abdomen. Resection lines for the conversion to RYGB were planned with regard to the 3D-CT, which
showed perfectly the positioning of the Silastic ring and the length of the vertical partition staple line
[Figure 3A-C].
Cases 4 and 5
Implants and their anatomical position can be surround-viewed from all angles and sides, due to full 360°
rotatability of the images [Figures 4 and 5].
Case 6
A patient after RYGB. Fully distended Candy Cane, visible from different angles [Figure 6A and B].
DISCUSSION
Besides the very detailed anatomical pictures, as shown above, which are invaluable as indication and
surgery planning guidance in complex revisional surgery, by far the most convincing advantage of 3D-CT
is the additional possibility of volumetry.
Weight regain is of special concern in bariatric patients and effective therapy necessitates an objective
[9]
measurement of gastric volume. Concordantly, our results and the recent results of Hanssen et al. clearly
