A Study On The Application Of 3D Printing In Laparoscopic Myomectomy Of Multiple Uterine Fibroids

Objective:To explore the application value of 3D printing technique assisted laparoscopic myomectomy in the treatment of multiple uterine fibroidsMethods:20 patients undergoing laparoscopic myomectomy for multiple uterine fibroids in Jiangxi Provincial people’s Hospital from March 2018 to August 2019 were randomly divided into two groups: 3D printing group(n=10)and control group(n=10).The corresponding 3D printing models of uterus and uterine fibroids were constructed and used in auxiliary surgery,and 10 cases in the control group were examined by traditional MRI images.Through the comparative analysis of the intraoperative,postoperative and follow-up observation indexes of the two groups and the knowledge of patients and their families about uterine fibroids,this paper preliminarily explores the application value of 3D printed model in laparoscopic myomectomy in the treatment of multiple uterine fibroids.Results:All the 20 patients were followed up after discharge.The results showed that in the 3D printing group,compared with the control group,no matter the operation length(99.8±18.2)min vs.(119.9±23.0)min,the intraoperative blood loss(92.7±14.2)ml vs.(108.3±12.5)ml,the number of fibroids excluded(3.7±0.8)vs.(3.0±0.5),the number of fibroids remaining cases(2 cases/20.0%)vs.(6 cases/60.0%),the postoperative anal exhaust time was(21.2±3.5)h vs.(26.7±3.9)h,the postoperative hospitalization days were(4.4±0.5)d vs.(5.2±0.8)d,3D printing group were significantly better than those in control group(P<0.05).There was no statistically significant difference between the two groups in terms of intraoperative complications and clinical symptom improvement rate 3-6 months after surgery(P>0.05).No postoperative complications occurred in the two groups,and no recurrence of myoma was found in the follow-up of 6 months.By comparing the scores of patients and / or their family members in the two groups after preoperative doctor-patient communication,the results showed that the average score of the 3D printing group and the control group was(69.2±15.2)points vs.(53.6±17.8)points,the former was significantly higher and the difference was statistically significant(P<0.05).Conclusion:The 3D printed uterine and fibroid models provide a new anatomical perspective different from the traditional two-dimensional tomography,featuring stereoscopic,vivid and high reduction,which improves the positioning accuracy of multiple fibroids,reduces the chance of myoma residual and relapse,and contributes to the improvement of surgical efficacy,efficiency and safety.In terms of doctor-patient communication,3D printing model is relatively easy to understand,which is conducive to win the understanding,cooperation and trust of patients.
