Clinical Analysis Of Intractable Intrauterine Pregnancy Residues Treated By Myosure Intrauterine Tissue Resection System And Hysteroscopic Electric Resection

Objective:To compare the clinical efficacy of Myo Sure intrauterine tissue resection system and Hysteroscopic electric resection in the treatment of Intractable intrauterine pregnancy residue.Method:Retrospective analysis of 70 cases of refractory intrauterine pregnancy residue treated in Jiangxi Provincial Maternal and Child Health Hospital from September 2017 to February 2018,among them 35 patients underwent the surgical resection of Myo Sure intrauterine tissue(referred to the Myo Sure group)and 35 patients treated by Hysteroscopic electric resection(referred to the Hysteroscopy group).To analyze the clinical effect of two kinds of surgical treatment for intractable intrauterine pregnancy residue.And to observe the mean time of operation,intraoperative bleeding volume,postoperative hospitalization days,correlation between intraoperative bleeding volume and CDFI blood flow of intrauterine residual pregnancy,days of recovery of menstruation after operation,changes of menstrual volume before and after operation,success rate of one operation,degree of satisfaction of patients and so on.(We set the criteria for the determination of satisfaction and dissatisfaction.Satisfaction: there was no effect on quality of life after operation and good therapeutic effect,for example: menstruation did not change significantly,and do not need to re-surgery.Dissatisfaction: refers to feeling uncomfortable after surgery and having an bad effect on the quality of life.For example: menstrual changes or even reoperation).All patients were followed up.Results:The mean operative time were(19.69±10.06)minutes in Myo Sure group and(25.51±13.21)minutes in Hysteroscopy group,The difference was statistically significant(t=2.077,p?0.05);The days of recovery of menstruation after operation were(30.94±5.11)days in Myo Sure group and(34.03±7.47)days in Hysteroscopy group,The difference was statistically significant(t=2.177,p<0.05);The intraoperative bleeding volume were(7.20±6.35)ml in Myo Sure group and(8.91±5.21)ml in Hysteroscopy group,The difference was not statistically signifcant(t=1.234,p > 0.05);The postoperative hospitalization days were(1.66±0.54)days in Myo Sure group and(1.71±0.46)days in Hysteroscopy group,The difference was not statistically significant(t=0.478,p>0.05);There were no difference in menstrual volume before and after operation between Myo Sure group and Hysteroscopy group(p>0.05);The success rate of one operation were 100% in Myo Sure group and 97.40% in Hysteroscopy group,and there was no difference between them(?2=1.401,p>0.05);The degree of patient's satisfaction were respectively 97.40% in the Myo Sure group and 91.43% in the Hysteroscopy group,and the difference was not statistically significant(?2=0.265,p>0.05);There were no difference between intraoperative blood loss and residual CDFI blood flow(r=0.103,p>0.05).Conclusions:Comparing the clinical efficacy of the two groups of surgical methods,the mean time for the surgery performed by the Myo Sure intrauterine tissue resection system was shorter than that of the Hysteroscopic resection and the menstruation was restored earlier than that of the hysteroscopic resection.And there was no significant change in the amount of menstruation before and after the operation.
