Objective:To investigate the value of digital medical 3D technology versus traditional 2D technology in the diagnosis and treatment of solid abdominal tumors in children. Methods:A total of 80 children with solid abdominal tumors who received surgical treatment guided by digital medical 3D technology at Guigang People's Hospital from January 2018 to January 2022 were included in the observation group. An additional 80 children with solid abdominal tumors who received surgical treatment guided by traditional 2D technology at the same hospital from January 2014 to December 2017 were included in the control group. Clinical efficacy was compared between the two groups.Results:The surgical time, intraoperative blood loss, postoperative exhaust time, postoperative hospital stay in the observation group were (111.8 ± 28.9) minutes, (26.8 ± 25.2) mL, (2.2 ± 1.2) days, (7.5 ± 1.4) days, respectively, which were significantly shorter or less than those in the control group [(193.1 ± 66.0) minutes, (86.2 ± 47.0) mL, (3.7 ± 0.9) days, (12.2 ± 3.5) days, t = 7.00, 6.88, 5.87, 7.53, all P < 0.05]. The complete surgical resection rate in the observation group was significantly higher than that in the control group [92.5% (74/80) vs. 81.3% (65/80), χ2 = 4.44, P < 0.05]. The incidence of complications in the observation group was significantly lower than that in the control group [6.3% (5/80) vs. 16.3% (13/80), χ2 = 4.00, P < 0.05]. Conclusion:The utilization of digital medical 3D technology in the surgical treatment of solid abdominal tumors in children can markedly decrease surgical time, reduce intraoperative blood loss, promote postoperative recovery, achieve a high surgical resection rate, and minimize postoperative complications.
