This case report describes the use of a three-dimensional reconstruction technique to plan the abdominal incision in order to avoid incision-related complications in a 53-year-old female patient who had had a cystic mass in the liver for 16 years and had undergone four previous surgeries. The patient presented with a recurrent cyst. The surgical team used three-dimensional reconstruction to model the liver mass, the area of abdominal wall weakness due to previous surgeries, bowel adhesions, skeletal structure and whole abdominal contour. The models were superimposed upon each other to reveal the relationship between the various features so that the optimum incision point could be selected so as to avoid the area of abdominal wall weakness, bowel adhesions and vital organs. The actual surgical incision was made based on the three-dimensional reconstruction models and the surgeon was able to avoid the area of abdominal wall weakness and bowel adhesions as planned. No incisional hernia and wound infection were observed postoperatively and the incision healed well. The three-dimensional reconstruction technique for preoperative surgical incision planning on patients with a history of multiple abdominal surgeries can minimize incision-related complications and achieve good therapeutic results.

The tomographic reconstruction from multiple projections of cellular components, within a thick section, offers a way of visualizing and quantifying their three-dimensional (3D) structure. However, asymmetric objects require as many views from the widest tilt range as possible; otherwise the reconstruction may be uninterpretable. Even if not for geometric obstructions, the increasing pathway of electrons, as the tilt angle is increased, poses the ultimate upper limitation to the projection range. With the maximum tilt angle being fixed, the only way to improve the faithfulness of the reconstruction is by changing the mode of the tilting from single-axis to conical; a point within the object projected with a tilt angle of 60° and a full 360° azimuthal range is then reconstructed as a slightly elliptic (axis ratio 1.2 : 1) sphere.
