Background: Laparoscopic sleeve gastrectomy (LSG) has now a
surge in popularity in treatment of morbid obesity patients. Multislice computed tomography has an increasing role in management of
this patients’ group through the availability and efficiency of post
processing reconstructive facilities of MSCT software in 3D
reconstruction. The purpose of this study is to evaluate MSCT-based
volumetric assessment of stomach and gastric sleeves in patients
before and after bariatric surgery and correlation between operative
gastric volume reduction and body weight reduction.
Methods: Thirty sleeve gastrectomy-candidate patients received
abdominal MSCT immediately after oral administration of an ionic
contrast agent solution. The examination was done pre and three
months postoperatively. The gastric and sleeve volumes were
measured via 3D volume rendering and 3D masks on dedicated
workstations.
Results: The correlation between the body weight and gastric volume measured initially in the
preoperative state in the studied patients was found to be insignificant. The correlation between
body weight reduction percentage and gastric volume reduction percentage in the studied patients
was found to be also insignificant.
Conclusion: MSCT allows crucial anatomical measurements and provides helpful information
about the relation between gastric volume reduction and body weight reduction in sleeve
gastrectomy-candidate obese patients. |
