A new technique for the 3D reconstruction of the incisional hernia: A pilot study.

Purpose: This study aimed to accurately evaluate incisional hernias with a new three-dimensional (3D) reconstruction technology, proving surgeons more information for intuitive and accurate judgments about incisional hernia to minimize the perioperative complications and recurrence rate.

Method: This was a pilot study using a new technique, 3D reconstruction, based on computed tomography (CT) scans to measure abdominal wall defect, herniary area, herniary volume, abdominal cavity volume, and the volume of transverse, oblique, and recti abdominis in three patients with incisional hernias.

Results: The 3D reconstruction technique made automated segmentation of the bony skeleton, skin, outer abdominal wall, vessel, and hernia sac. The hernia sac, abdominal muscles, and their anatomic relationship were clearly illustrated in 3D reconstruction images. Moreover, abdominal cavity volume; herniary diameter, area, and volume; and the volume of transverse, oblique, and recti muscles could be evaluated through 3D reconstruction images. Surgeons can also freely combine, rotate, scale, and move the 3D reconstruction mode, modify the name and transparency of the 3D reconstruction model, and observe the internal structure of the tissue and the size, shape, and location of the lesion from multiple angles for better and accurate judgments.

Conclusion: The herniary diameter, area, and volume and the volume of transverse, oblique, and recti abdominis can be accurately calculated through this 3D reconstruction technology. A three-dimensional vision of the abdomen through this technology can objectively and quantitatively evaluate the situation of incisional hernia, providing a more realistic means for diagnosis and treatment of incisional hernias.
