Three-dimensional visualization technique in endoscopic breast-conserving surgery and pedicled omentum for immediate breast reconstruction.

ABSTRACT

PURPOSE: To evaluate the three-dimensional visualization technique (3DVT) in endoscopic breast-conserving surgery (EBCS) and pedicled omentum for immediate breast reconstruction. METHODS: Clinical data of 256-slice multi-detector CT scanning from 52 patients (group A) were introduced into self-developed Medical Imaging 3D Visualization Systems (MI-3DVS) for individualized segmentation, 3D reconstruction and volume calculation. The surgical process was designed according to the 3D model. Next, the EBCS and pedicled omentum breast reconstruction were performed according to the preoperative design. Finally, the operating time, blood loss, length of postoperative hospital stay, complications and cosmetic outcomes in group A were compared to 44 patients in group B, who underwent the same operation without 3DVT. RESULTS: The 3DVT can be used to analyze the location of the breast tumors and determine the excision extension of the breast precisely. Compared to group B, group A had the advantage of less bleeding, shortened operating time and earlier discharge (p < 0.05). The cosmetic results of group A were more satisfactory than those of group B (p < 0.05). After a postoperative follow-up of 6-30 months, none of the patients in either group showed any signs of recurrence. CONCLUSIONS: 3DVT can be used to design the surgical process preoperatively and results in positive therapeutic and cosmetic outcomes in EBCS and pedicled omentum for immediate breast reconstruction.
