ABSTRACT
Objective To investigate the effect of laparoscopic hysterectomy and open hysterectomy on ovarian hemodynamics.Methods Selected 132 patients who underwent hysterectomy,among them,76 cases (laparoscopic group)underwent laparoscopic hysterectomy,56 cases(open group)underwent open hysterectomy.The preoperative and postoperative ovarian artery hemodynamic parameters,T cell subsets and serum hormone index of the two groups were observed.Results In the observation group and the control group postoperative 48h,the pulsatility index(PI), resistance index (RI),systolic blood flow velocity maximum (Vmax)and diastolic stage blood velocity minimum (Vmin)decreased(all P <0.05),which of postoperative 2 weeks increased(all P <0.05).The RI,Vmax and PI in the observation group postoperative 48h and 2 weeks were (1.17 ±0.16)and (1.30 ±0.14),(0.66 ±0.11)and (0.70 ±0.06),(11.80 ±3.10)m/s and (12.17 ±3.26)m/s,(3.01 ±0.19)m/s and (2.98 ±0.20)m/s,which were all higher than those in the control group(t =-10.637 and -7.609,-5.880 and -2.583,-5.084 and -3.271,-13.660 and -4.826,all P <0.05).The CD +4 and CD +3 T cells levels of the observation group and control group postoperation were increased(all P <0.05),and the CD +8 T cells levels were decreased(all P <0.05).The CD +4 and CD +3 T cells levels of the observation group postoperative 48h and 2 weeks were (43.50 ±3.50)% and (47.20 ±3.16)%, (73.50 ±6.17)% and (80.06 ±9.20)%,which were higher than those in the control group(t =-6.859 and -5.599,-5.515 and -4.853,all P <0.05),while the CD +8 T cells were (37.52 ±5.10)% and (34.10 ±3.20)%,which were lower than those in the control group(t =3.007 and 3.214,all P <0.05 ).The estradiol(E2 )levels of the observation group and control group were significantly decreased(all P <0.05),follicle stimulating hormone(FSH) levels were significantly increased(all P <0.05).The E2 levels of the observation group postoperative 1 month and 3 months were significantly lower than those of the control group(all P <0.05),FSH levels were significantly higher than those of the control group (P <0.05).Conclusion The effect of laparoscopic hysterectomy on ovarian hemodynamics, ovarian function and immune function is small,and it is worth to be popularized in clinical application.
