Abstract：Objective To explore the application and perioperative nursing value of 3D medical visualization system (IQQA?-3D
Liver assessment and treatment planning assistance system) in guiding precise resection of liver tumors. Methods The results of
preoperative CT or MRI enhancement examinations were collected from 43 hepatectomy. The IQQA?-3D Liver system was used
for simulated surgery, and the simulated liver volume was calculated and compared with the actual liver volume. In the meantime,
the perioperative care was observed with the aid of 3D visualization treatment planning assistance system technology. Results 43
patients had a simulated resected liver volume of (390.08±441.52) cm3, and the actual resected liver volume was (408.54±469.32) cm3. The
comparative difference was not statistically significant (t=0.297, P=0.693). There was a significant positive correlation between the
simulated and actual resected liver volumes with r=0.968, P<0.01. And it was significantly beneficial for postoperative rehabilitation
care. Conclusion The IQQA?-3D Liver assessment and treatment planning assistance system allows 3D classification of lesions,
liver parenchyma, and hepatic venous system, and reconstruction a single liver model. The spatial relationship between the lesion
and the hepatic venous system is demonstrated, and liver screening can be carried out by simulating the operation function, and the
volume of each part of the liver can be calculated. It has great significance to guide the accurate resection of liver lesions and tumor
masses. Meanwhile, the system can accelerate the recovery of gastrointestinal function and shorten the length of hospital stay, which
has certain guiding value.
