Virtual modeling in abdominal surgery: experience of application in surgery of liver, spleen and pancreas
Abstract
Computer modeling based on multispiral computer tomography (MSCT) data – a technique that allows
to combine all four phases in one 3D integral image. Systems for segmentation and pre-operative
3D-modeling with possible intraoperative navigation are actively being studied nowadays.
Purpose. То evaluate the experience of application of Avtoplan system in preoperative planning
in preparation for abdominal surgery.
Results. We examined 60 patients treated in surgical departments of Clinics of Samara State Medical University. Average reduction in operative time for all nosologies was 11.5%. There were no
deaths in postoperative period in the study group.
Conclusions. Preoperative simulation may more accurately describe anatomical relationships in
the operative area. In patients with planning spleenectomy simulation allowed to choose the optimal type of operation. For the purpose of pancreas surgery simulation can effectively visualize
vessels passing through modified topography to avoid intraoperative injury. The system allows to
make a virtual resection plan and quantify volume of resected and stored parenchyma while planning a liver resection.
