To explore the value of medical three-dimensional visualization technology in preoperative precise assessment for abdominal wall tumor.

The clinical data of 23 patients were analyzed retrospectively from November 2017 to April 2019 in Shanghai Ninth People's Hospital. CT scanning was performed and the data was stored in the form of DICOM. Three-dimensional reconstruction and related data analysis were performed by the Medraw software, which can accurately show the calculation of abdominal wall tumor volume, abdominal wall defect area, abdominal wall defect classification and zoning, and develop a personalized surgical plan.

Twenty three patients underwent three- dimensional reconstruction of abdominal wall tumors and designed a personalized surgical plan. Among them, there were 15 cases of primary abdominal wall tumor and 7 cases of secondary abdominal wall tumor. Preoperative three-dimensional reconstruction could accurately obtain the average volume of abdominal wall tumors (355.18±820.13) cm³, abdominal wall defect area (216.2±145.49) cm². The mean blood loss was (334.78±271.54) ml, and the average hospital stay was (21.22±8.65) days. The mean follow-up time was (12.1±6.87) months, the patient survival rate was 86.96% (20/23), the primary abdominal wall tumor recurrence rate was 13.33% (2/15), and the secondary abdominal wall tumor recurrence rate was 28.57% (2/7); the incidence of postoperative complications was 34.78% (8/23).

Three-dimensional visualization technology can be used for the accurate evaluation of patients with abdominal wall tumors before surgery and designed a personalized surgical plan.
